The hospitality sector is feeling the strain of the government’s ongoing austerity campaign which has sharply curtailed hotel bookings and meeting activities nationwide which has been forced to reduce the working hours of its part-time staff due to a significant decline in bookings from local government agencies their hours have been cut in half,” said Bintang Adhipradipta Workers affected include those in the hotel’s restaurant and housekeeping departments Despite its strategic location near Patimban Port -- recently launched as a major export hub particularly for the automotive industry -- the hotel has seen a dramatic drop in activity “We used to host corporate and government events regularly but those have virtually disappeared since the start of the year,” Bintang said Even during the usually busy Eid al-Fitr holidays when all 107 rooms were typically fully booked the hotel recorded an occupancy rate of only around 30 percent this year According to the Indonesian Hotel and Restaurant Association (PHRI) the national hotel occupancy rate dropped to around 20 percent last month a steep decline from 40 to 60 percent during the same period last year traditionally one of the peak periods for domestic travel -- alongside the year-end holidays -- has become a bellwether for industry performance from Bogor and Malang on Java Island to Medan in North Sumatra reported underwhelming occupancy during this year’s Eid Even popular tourist destinations like Bali and Yogyakarta saw lower-than-usual bookings the national occupancy rate stood at 37.77 percent a slight decline of 0.51 percentage points compared to the same period last year according to the Central Statistics Agency (BPS) A significant portion of hotel revenue has traditionally come from MICE (meetings particularly those sponsored by the government This vital income stream has nearly dried up following President Prabowo Subianto’s announcement of sweeping cost-cutting measures aimed at saving over Rp 300 trillion in government spending These measures include strict restrictions on non-essential travel and meetings by government officials and state agencies PHRI Chairman Hariyadi Sukamdani acknowledged earlier this month that the hotel industry is heavily reliant on government spending He noted that 40 percent of hotel revenues nationally -- and up to 70 percent on Java Island -- come from government bookings He also revealed that two hotels in Bogor had ceased operations ahead of the Eid holiday due to slumping demand Hendrik Yaputra TEMPO.CO, Jakarta - Thousands of citizens received gifts and souvenirs after attending President Prabowo Subianto’s Eid open house at the Presidential Palace in Central Jakarta on Monday was among the attendees who received a gift bag “I also got an umbrella,” he said at the Presidential Palace Complex on Monday According to the Presidential Secretariat’s Press more than 5,000 gift and souvenir bags were distributed to citizens The gift bags included food and drink items such as instant noodles while the souvenir bags contained an umbrella Herman admitted that he was disappointed because he couldn't convey his aspirations to the head of state President Prabowo only greeted and shook hands with the public at the same location namely at the Presidential Palace Courtyard hoped to convey his aspirations to President Prabowo to create disability-friendly policies "So that people with disabilities can get jobs without discrimination," he said at the Presidential Palace Complex Herman became a person with physical disabilities after contracting polio at the age of 7 The disease caused the nerves in his legs to shrink He claimed he could still do various kinds of work is that society has stereotyped that people with disabilities cannot work This perception makes Herman upset because it restricts the access of people with disabilities to work people with disabilities seeking jobs are looked down upon," he said This stereotype hinders the development of people with disabilities Herman was determined to ask Prabowo to facilitate job access for people with disabilities He wanted job opportunities for people with disabilities to be non-discriminatory I haven't had the chance to convey this," he said The same aspiration was expressed by Stella This North Jakarta resident has a 24-year-old son with autism named Justin people with autism find it more difficult to get jobs compared to other disabilities Therefore, Stella hopes that Prabowo will provide easy job access for all people with disabilities maybe they would be paid attention to," she said at the Presidential Palace Courtyard Editor's Choice: Comparison of Prabowo and Jokowi's Eid Open House at the Presidential Palace Click

Semeru Erupts 3 Times This Morning, Sends Ash 700 Meters High WHO: Hand Hygiene is Essential, Medical Gloves Are Not a Substitute The cost of returning home for the 2025 Eid holiday is projected to increase by up to 30 percent due to rising fuel prices and soaring transportation fares economic uncertainty and a wave of layoffs continue to loom over many workers families are expected to allocate between Rp 3 million ($181.5 million) and Rp 5 million for mudik in 2025 compared to just Rp 2.5 million to Rp 4 million in 2024," said Achmad Nur Hidayat an economist and public policy expert from UPN Veteran Jakarta Achmad said the increased costs may force lower-income workers to either cancel their trips or reduce their Eid-related expenses. Surveys show that only 146.48 million Indonesians will travel this Eid homecoming season marking a 24 percent drop from 193.6 million travelers recorded last year A decline in homecoming trips could impact local small businesses that rely on holiday travelers sectors such as transportation and tourism—key seasonal economic drivers—could also suffer The economic strain comes at a time when Ramadan and Eid typically see a surge in consumer spending making this period the peak of Indonesia's consumption cycle Achmad projected that consumer spending during Ramadan 2025 could reach Rp 1,188 trillion with growth estimated at only 5-7 percent—a slowdown compared to the 9-12 percent growth recorded in 2023 and 2024 "Recent data shows that while seasonal spending still increases the growth rate is lower than in previous years," Achmad said Indonesia’s Chamber of Commerce (Kadin) estimates Eid-related financial turnover will reach nearly Rp 138 trillion The decline is based on assumptions that the average family spends Rp 3.75 million during Eid travels Kadin Deputy Chairman Sarman Simanjorang attributed the drop to mass layoffs Many families are prioritizing savings for school expenses as the academic year approaches falls just months after the year-end holidays Indonesia merupakan negara pemilik garis pantai terpanjang kedua di dunia setelah Kanada yang dilansir memiliki panjang pantai 202.080 km2 Badan Informasi Geospasial (BIG) menyebutkan panjang garis pantai Indonesia mencapai 99.093 km2 dengan luas wilayah perairan sekitar 6.315.222 km2 FAO (Food and Agriculture Organization) di tahun 2007 menyatakan bahwa Indonesia merupakan negara terbesar yang memiliki hutan mangrove dengan luas sekitar 3 juta hektare atau 19% dari luasan hutan mangrove di dunia luas hutan mangrove Indonesia mencapai 8,2 juta hektare dengan rincian 2,5 juta hektare dalam kondisi baik dan 6,7 juta hektare dalam kondisi rusak Angka tersebut berdasarkan data dari Kementerian Lingkungan Hidup dan Direktorat  Jendral Rehabilitasi Lahan dan Perhutanan Sosial (Dirjen RLPS) bisa disimpulkan bahwa ekosistem mangrove di pesisir Indonesia sedang dalam kondisi mengkhawatirkan ekosistem mangrove memiliki peranan penting sebagai fungsi ekologi Dan akibat masifnya pembukaan lahan (deforestasi) di kawasan pesisir serta masih minimnya upaya konservasi mengakibatkan munculnya sejumlah persoalan lingkungan misalnya abrasi Tak jauh berbeda dengan wilayah pesisir di Jawa Barat menurut Dinas Kelautan dan Perikanan Provinsi Jawa Barat tahun 2008 lalu luasan hutan mangrove di tanah Pasundan sekitar 38 ribu hektare dimana 18 ribu hektare mangrove dalam keadaan rusak dan mungkin saja jumlah tersebut bisa bertambah apabila melihat kondisi lingkungan dewasa ini Ada 11 kabupaten/kota yang sebagian wilayahnya memiliki kawasan pesisir pantai diantaranya tepatnya di wilayah pesisir Pantai Utara (Pantura) ekosistem mangrove seluas kurang lebih 1000 hektare sebagian besar dalam kondisi rusak parah salah satu anggota Tim Ekpedisi pesisir Wanadri (Perhimpunan Penempuh Rimba dan Pendaki Gunung) kelompok pengiat alam bebas yang telah melakukan pengamatan selam 54 hari di Desa Mayangan Dari hasil pengamatannya menujukan bahwa rusaknya ekosistem mangrove di pesisir Pantura berpengaruh pada lingkungan sekitar di pesisir Pantura telah terjadi penyusutan lahan daratan yang terkikis oleh air laut Sehingga banyak sekali daratan yang habis karena terendam air rob Diduga sepajang hampir 2 km lebih garis pantai juga sudah mundur “Kami mengamati itu karena di pesisir Pantura Subang merupakan areal bermain Wanadri sudah sejak lama Sehingga kami menyadari kok setiap tahunnya hutan mangrove semakin berkurang untuk itu kami melakukan pengamatan mengenai aspek lingkungan dan sosial di kawasan Pantura,” kata Imam saat ditemui di acara “Suka Cita Pesisir Nusantara” di Museum Geologi timnya menemukan pohon–pohon mangrove banyak yang tumbang dan rusak Kemudian menemukan ubur–ubur dan brangkas (hewan endemik) yang mati akibat dari kondisi lingkungan yang tidak seimbang garis pantai terbaru dan kerusakan pantai yang terjadi sudah sedikit sekali daratan yang ada hanya air rob sehingga penyelurusan pun mesti dilakukan menggunakan perahu Kemudian kami memasang alat pemantau pasang surut air laut selama 29 hari Dan selama proses berlangsung ternyata disana sudah mengalami penurunan muka tanah,” papar Iman Dia menyebutkan banyak rumah masyarakat yang hancur akibat terkikis abrasi Bahkan sampai ada rumah warga yang hampir setiap hari tergenang banjir rob Itu menjadi permasalahan bagi masyarakat pesisir khusunya di Pantura Sudah banyak yang pindah tetapi tidak sedikit dari warga memilih bertahan dengan alasan tidak ada biaya Imam menegaskan apabila tidak ada upaya konservasi pemulihan ekosistem mangrove dapat diprediksikan 15 tahun kedepan akan seperti apa kondisinya anggota Wanadri yang meneliti sosial budaya di pesisir Pantura mengatakan ada literatur menyebutkan bahwa mangrove sangat mendukung lingkungan disekitarnya timnya mengamati tentang bagaimana kehidupan dan penghidupan masyarakat pesisir dengan kondisi mangrove yang telah rusak Dia mengungkapkan rusaknya mangrove berdampak pada 3 desa yang terancam tenggelam yaitu Desa Mayangan Jumlah penduduk ketiga desa tersebut sekitar 6.627 jiwa dengan rincian 74.1% masyarakat tergolong tidak mampu 36% tidak lulus dari Sekolah Dasar (SD) serta hanya 23% masyarakat yang memiliki MCK sendiri sebagian besar masyarakat berprofesi sebagai nelayan tradisional Nelayan ini tergolong nelayan yang hidupnya paling sulit karena keterbatasan peralatan untuk melaut “Jika Bu Susi (Menteri Kelautan dan Perikanan) mengatakan kapal yang kapasistas kecil adalah 10 ton Sementara kapal  – kapal yang ada di Pantura Subang maksimal hanya 2 ton ikan atau setengah kuintal kapasitas tangkapnya,” papar dia Akibat rusaknya mangrove di sekitar pesisir juga mengharuskan mereka melaut lebih jauh Dengan peralatan dan perahu kecil mereka pun kadang pulang dengan hasil yang kurang memuaskan Dari segala keterbatasan tersebut kehidupan nelayan disana mau tidak mau harus mendapat penghasilan dan oleh karena itu banyak yang membuka lahan tambak dengan konsekuensi menebang hutan mangrove Usamah berujar sebetulnya di daerah sana sudah banyak tokoh masyarakat yang peduli tetapi hambatan  mereka yakni belum kuat untuk mengajak masyarakat  yang lain Seharusnya yang perlu ditekankan disini bahwa masyarakat setempat adalah subjek utamanya mereka yang merasakan dan mereka juga pun yang merasakan perubahan Jadi dari perbaikan harus timbul dari masyarakat itu sendiri Tetapi tidak cukup dari kesadaran masyarakat tapi juga harus ada dari peran semua pihak termasuk pemerintah,” ucap dia banyak program – program pemerintah yang kurang tepat sasaran Program tersebut misalnya pemerintah memberikan bantuan seperti jaring baru untuk mendapatkan barang tersebut mereka bisa membeli dari hasil melaut mereka Tetapi yang dibutuhkan para nelayan di Pantura adalah pemerintah menindak oknum – oknum mengambil pukat – pukat yang merugikan masyarakat “Soal penegakan hukum dan pengawasan laut adalah urusan diluar kontrol kami pemerintah juga harus tegas soal permasalahan tadi Pola kebijakannya jangan top-down tetapi harus muncul dari kondisi yang terjadi di masyarakat,” kata dia mengaku prihatin dengan fenomena kerusakan alam yang terjadi di pesisir Indonesia Padahal sejatinya Indonesia adalah negara bahari Akan tetapi segala urusan lebih dibahas tentang daratan saja Jawa Barat dianugrahi kekayaan alam yang cukup melimpah mulai dari kawasan hulu yang subur dengan dikelilingi gunung – gunung api hingga garis pantai yang terbentang luas hingga ke Bali “Sudah seharusnya perhatian kita tidak hanya melihat daratan saja mari kita semangatkan kembali bahari kita sesuai dengan deklarasi Juanda,” kata Aat Dia juga menghimbau kepada seluruh elemen untuk peduli terhadap kelestarian lingkungan mulai dari hulu hingga ke hilir Diperlukan sinergi antara pemerintah dan masyarakat sebab urusan lingkungan merupakan urusan kehidupan serta tidak dititikberatkan pada satu kawasan saja tetapi menyeluruh   Facebook   Twitter

Basin is a tertiary sedimentary basin located in southern Central Java 2-D seismic reflection methods cannot provide a good estimation of the sediment thickness and the subsurface geology structure in this area the passive seismic tomography (PST) method was applied to image the 3-D subsurface Vp We used 70 seismograph borehole stations with a recording duration of 177 days 368 S phases were used as input for tomographic inversion 400-meter deep exploration well (Jati-1) located within the seismic network were used to constrain the shallow crustal layer of the initial 1-D velocity model The model resolution of the tomographic inversions was assessed using the checkerboard resolution test (CRT) we were able to sharpen details of the geological structures within the basin from previous geological studies and a fault could be well-imaged at a depth of 4 km We interpreted this as the main dextral strike-slip fault that controls the pull apart process of the Banyumas Basin We found prominent features of the velocity contrast that aligned very well with the boundary between the Halang and Rambatan formations as observed in the Jati-1 well data which is a potential structural trap for the petroleum system in the Banyumas Basin This was made possible due to the dense borehole seismographic stations which were deployed in the study area Based on the sedimentary basin map of Indonesia (Indonesia Geology Agency, 2009) there are at least 13 sedimentary basins on Java Island; eight of these are categorized as intermontane arc basins and are located in the southern part of Java Island are covered by Paleogene to recent volcaniclastic sediments; the presence of volcaniclastics causes poor quality data in the 2-D seismic reflection method which is used to determine the subvolcanic sediment FIGURE 1. Map of the regional geological structure and the Banyumas Basin boundary (modified from the Geology Agency., 2009; Muchsin et al., 2002; Armandita et al., 2009; Satyana, 2015; Lunt et al., 2009; Hidayat et al., 2020) the Citanduy Subbasin in the southwestern part of the anticline structure which is aligned in a NW–SE direction This has led to the growing popularity of PST for use as a method of hydrocarbon exploration According to the checkshot data from the Jati-1 well the Halang Formation has the most significant velocity contrast (around 9.4%) which was deposited below the Halang Formation Based on the velocity contrast of these two formations we attempt to delineate the subsurface geological structure of our study area FIGURE 2. (A) Regional geological map of the study area (modified from Budhitrisna, 1986; Supriatna et al., 1992; Kastowo, 1975; Simandjuntak and Surono, 1992; Djuri et al., 1996; Asikin et al., 1992) and (B) distribution of PST stations shown by red-colored inverted triangle The result of travel time tomography inversion is expected to image the condition of the geological structures related to the generation of the pull apart basin as well as the trapping mechanism for the petroleum system in this study area FIGURE 3. Comparison of top 20 km regional 1-D velocity (Koulakov et al., 2007) and local 1-D velocity using Jati-1 well checkshot data to specify a layered model or a 3-D velocity model. Jati-1 well checkshot data give a more detailed velocity contrast on the shallow crust. We used 1.74 as initial Vp/Vs ratio value for tomography inversion. The complete 1-D initial velocity model which we used in this study is shown in Supplementary Table S1 and D–D′ which show a comparison of the initial synthetic velocity model of the checkerboard test and the results of its recovery Based on these three resolution test methods we conclude that the entire regions of our study area from both horizontal and vertical cross sections can still be well resolved This resolved area will be further interpreted in relation to the geological structure identified from the cross sections We expect to reveal the regional geological structures strike-slip faults (such as the Gabon Fault and the Karangbolong Fault) in our horizontal section we expect to reveal the anticline structure that could be a potential structure trap for the Banyumas Basin Horizontal view of recovery from ±10% initial checkerboard resolution tests for Vp and Vp/Vs ratio Figure (A–D) are recovery of the Vp checkerboard test at 0–6 km depth while figure (E–H) show recovery of the Vp/Vs checkerboard test at 0–6 km depth Blue and red colors indicate positive and negative anomalies Random noise with a 0.1 s standard deviation was added to the synthetic travel time (A) The vertical cross section of a ±10% initial model checkerboard resolution test and the recovery checkerboard resolution test of the Vp (B) and Vp/Vs ratio (C) for A–A′ Travel time tomography inversion results are presented in vertical and horizontal cross sections of the Vp structure and in horizontal cross sections of Vs structure and Vp/Vs ratio which will be covered in the following discussion Horizontal cross sections will be presented in every 2 km starting from 0 km (mean sea level) while vertical cross sections will be presented on the sections passing through the Jati-1 well and oil seepage on the surface The cross sections of A–A′ and D–D′ passed through the Jati-1 exploration well and oil seepage on the surface while the cross sections of B–B′ and C–C’ passed through oil seepage on the surface Vertical cross sections that passed through oil seepage and the Jati-1 well were further analyzed for interpretation in several geological structures that have potential as hydrocarbon traps In this study, we also used the results of other geophysical studies such as the gravity anomaly map and 2-D seismic reflection sections (Tampubolon et al., 2014) to validate the vertical cross section of our seismic tomography results The surface geology and the residual gravity anomaly map are used as validation for our horizontal cross sections we tried to investigate the geological structure in the form of anticline which can be an ideal structural trap for the Banyumas Basin petroleum system; however detailed explanations related to lithological interpretations will not be presented in this article which is comparable to the residual gravity anomaly we can still delineate some similar geological features which are shown in the horizontal Vp section at a depth of 2 km It was seen that the velocity structure Vp has good compatibility with some geological features which has a relative NW–SE orientation and some lithological distribution patterns such as the outcrop of the Gabon Formation which is characterized by a high-velocity anomaly in the southwest part of the study area FIGURE 6. Previous studies available for the study area were used for comparison with our horizontal cross section results: (A) A residual gravity anomaly (modified from Hidayat et al., 2020), (B) the regional Miocene geological structure configuration of the southern part of Central Java (modified from Muchsin et al., 2002), and (C) the complete Bouger anomaly map (modified from Hidayat et al., 2020) TABLE 1. Facies analysis based on Jati-1 well log data (Tampubolon et al., 2014) Figure 8 shows the result of Vp/Vs ratio and the Vs structure. Compared to horizontal Vp structures, our results showed high Vp, Vs, and low Vp/Vs values were imaged at depths of 0–4 km around the Jati-1 exploration well region. We consider this region as the result of the Pliocene–Pleistocene tectonic compression (Pulunggono and Martodjojo, 1994) which formed an anticline structure and separated the Majenang and the Citanduy Subbasin which were imaged at depths of 6 km around this Jati-1 exploration well region might be an accumulation of Late Cretaceous–Eocene sediment Horizontal sections Vp/Vs ratio and the Vs structure at (A) 0 km depth and perturbation of Vs anomaly at (E) 0 km depth Based on an anomaly contrast of Vp/Vs ratio at 2 and 4 km depth we assume that Pamanukan–Cilacap strike-slip fault formed an echelon structure that controls the depocenter of the Banyumas Basin FIGURE 9. Overlay of oil seepage data distribution and Jati-1 exploration well to the vertical section of the Vp, Vs, and Vp/Vs ratio based on travel time tomography inversion results around the PST network (modified from Junursyah et al., 2019) We assume that the existence of this high Vp and the low Vp/Vs value in this region (shown by the black dashed curve circle) might be a possible reason why the Jati-1 well has not found any indication of liquid-bearing at a depth of 4400 m Line A–A′ and D–D′ intersected Jati-1 well (shown by black-colored inverted triangle) with a target depth of 4 the Jati-1 well is directly above the anticline structure as shown by Vp and Vs vertical sections Vp/Vs ratio shows a low anomaly region (<1.7) FIGURE 11. The residual gravity anomaly response (Hidayat et al., 2020) and the vertical cross sections of Vp which pass through the Jati-1 well in sections A–A′, D–D′, B–B′, and C–C′. Blue line indicates geological contact between the Halang Formation and the Rambatan Formation, which is also confirmed by interpretation of Jati-1 well (Tampubolon et al., 2014) We also interpreted top of basement based on the high-velocity anomaly (>5 km/s) which is shown by red line The anticline structure was obtained at the intersection of the A–A′ and D–D′ cross sections as well as the location of the Jati-1 well drilling A similar structure was also obtained at the intersection of D–D′ and B–B′ cross sections The anticline structure is expected to be a good trapping mechanism for the Banyumas Basin The subsurface anticline pattern has the same pattern as the anticline trend that is exposed on the surface forming an elongated pattern in a NW–SE direction FIGURE 12. Directions along which the vertical tomographic sections have been compared to 2-D seismic reflection sections (Tampubolon et al., 2014) In the southwest of cross-section X–X′ we found an outcrop of the volcanic Gabon Formation which was deposited during the Oligocene–Miocene period and is also the oldest rock outcrop in the study area The high Vp and Vs anomaly at depth of 0 km (mean sea level) in the southwestern part of the X–X′ cross section is interpreted as an indication of the existence of these volcanic deposits The Cipari anticline trend separates two low anomalies; the Citanduy Subbasin The contrast of the velocity anomaly was found at both the X–X′ and the Y–Y’ cross sections at a depth of 1 which is interpreted as the geological contact between the Halang and the Rambatan formations Our PST network consisted of 70 stations with three components that were installed in the Banyumas Basin and covered 45 km × 60 km of the study area to perform a PST investigation of subvolcanic structures related to the petroleum system We managed to determine 354 events with 9370 P-phases and 9368 S-phases as our input for the tomographic inversion The application of a local 1-D velocity model succeeded in specifying the presence of a more detailed geological structure in a shallow depth We also assessed the resolution and reliability of our results using the checkerboard resolution test the area within our network is still well resolved and reliable for interpretation Application of the travel time tomography method by installing a dense seismograph station and a local 1-D velocity model using checkshot data can provide a satisfactory correlation with other geophysical methods and geologic structures related to the delineation of trapping mechanisms for the petroleum system in the Banyumas Basin Based on the results of our tomographic inversion we obtained geometries similar to geological structures in the form of fold structures with the top of the anticline found at the Jati-1 exploration well The top of the anticline is interpreted as a subsurface image of the Cipari anticline trend confirmed by the regional geology map The velocity contrast of the tomographic inversion results is interpreted as the geological contact between the Halang and Rambatan formations; this interpretation correlates with the results of the Jati-1 well interpretation Mudstone from the Halang Formation can be a caprock for the Banyumas Basin petroleum system with the anticline structure as a trap mechanism Our tomographic inversion results are highly comparable with those of previous studies Based on the comparison of the Vp horizontal cross section with the regional geological map in the study area the high-velocity anomaly shows a comparable pattern with the distribution of volcanic rocks from the Gabon Formation in the southwest part of the study area based on the comparison between the horizontal cross section and the residual gravity anomaly the high-velocity anomaly with a NW–SE orientation is interpreted as a subsurface image of the Cipari anticline trend that separates the Citanduy Subbasin and the Majenang Subbasin at a depth of 2 km Based on horizontal cross sections of the Vp/Vs ratio at depths of 2 and 4 km we suggested that the Pamanukan–Cilacap strike-slip Fault likely formed an echelon structure that controlled depocenter in our study area We assume this may be the possible reason why the Jati-1 well has not found any rock formations older than the Middle Miocene–aged Pemali Formation and it also explains why there are low gravity anomaly regions around Jati-1 well Based on our Vp and Vs structure results at depths of 0 and 2 km the Pamanukan–Cilacap dextral strike-slip faults structure cannot be clearly delineated; this confirms that depths of 0–2 km are still dominated by sediment deposited after this fault structure was formed (Late Miocene–Quaternary) This interpretation is validated by Jati-1 exploration well data which show the presence of Late Miocene sedimentary rocks from the Rambatan Formation up to a depth of 2 km The top basement of the Banyumas Basin was obtained from the results of vertical cross sections showing high P-wave velocity anomalies which are greater than 5,000 m/s; characterized by red line in the vertical cross sections of Vp From the resulting model of our vertical cross section we estimate that the depth of the Banyumas Basin top basement has an average depth of around 8 km Deposition of thick sedimentary rocks provides opportunities for the presence of petroleum systems in the Banyumas Basin This study has succeeded in determining several zones of geological features which are potential structural traps of the petroleum system in the Banyumas Basin although the type of stratigraphic traps in the form of reef and onlap cannot be resolved The seismic velocity tomograms presented in this study are available in the article/Supplementary Material;

integrity team to safeguard the quality of each article we publish Homecoming trips would start to peak four days before Eid al-Fitr Indonesians usually return back to their hometowns to see their families and loved ones as many as 193.6 million people are expected to travel this year This is equivalent to 71.7 percent of the country’s total population The Eid exodus is about 50 percent higher than that of last year “So [the homecoming travel] will likely begin four days before Eid We will see [people’s mobility] skyrocketing on those days,” Transport Minister Budi Karya Sumadi told reporters in Jakarta on Monday People are advised to travel at a much earlier date to avoid traffic including state-owned enterprises and the armed forces are providing free rides on buses and ships “So it’d be better to use the government’s free services,” Budi said The national police has also readied what it calls the “Ketupat Operation” in which it deploys its personnel to make sure people can travel safely This operation will run from April 4-16.  The police have also identified areas that are prone to traffic accidents the traffic accident rate is expected to decline [last year] versus 2022 But because the homecoming travel will rise this year we hopefully can keep it under control this year,” National Police Chief Listyo Sigit Prabowo said Floods following heavy rains that started on Sunday have inundated several areas in West Java on Wednesday forcing thousands of people to leave their homes and rice fields.  The Citarum and Cibeet River's overflow submerged at least 4,545 houses across 12 sub-districts in the Karawang district the second-largest rice producer in the province after Indramayu The flood submerged at least 410 hectares of rice fields according to reports from the Karawang Regional Disaster Mitigation Agency (BPBD).  The flood also forced farmers to harvest their rice ahead of time to minimize their losses.   rescue teams had to evacuate local residents in the Pamanukan subdistrict in Subang to a temporary shelter under a large flyover a critical link in Java's northern coastal highway (Pantura). The flood also caused congestion along the road leading to the flyover. The flood victims were in dire need of clean water Subang BPBD said the floods affected  75 villages across 11 sub-districts in the district, displacing at least 32,000 people A survey conducted by the Transportation Ministry reveals that an estimated 193.6 million people equivalent to approximately 71.7 percent of Indonesia's population are anticipated to embark on the Eid exodus this year This represents a significant increase of 56.4 percent compared to the movement observed during the 2023 Eid which was estimated at 123.8 million people The survey carried out in collaboration with the Transportation Policy Agency the Ministry of Communication and Informatics aims to provide valuable insights for coordinated efforts in handling the increased travel during the festive season both operationally and in terms of policy with ministries and agencies at the central government and the private sector," said Transportation Minister Budi Karya Sumadi on Monday The survey results have been reported to President Joko "Jokowi" Widodo and shared with relevant stakeholders Minister Budi Karya Sumadi outlined the government's commitment to implementing effective policies to anticipate an influx of homecoming travelers preventing congestion in hubs and road sections These policies include regulating the timing of homecoming offering early discounts on mass transportation fares especially in areas at risk of experiencing extraordinary congestion The survey results indicate that the most common origin for travel is East Java at 16.2 percent (31.3 million people) followed by Greater Jakarta at 14.7 percent (28.43 million people) and Central Java at 13.5 percent (26.11 million people) the most common destinations are Central Java at 31.8 percent (61.6 million people) East Java at 19.4 percent (37.6 million people) and West Java at 16.6 percent (32.1 million people) Regarding transportation choices for Eid al-Fitr the survey indicated that trains are the most favored option at 20.3 percent with a potential movement of 26.6 million people (13.7 percent) The estimated peak return day is  Sunday April 14 with a potential movement of 41 million people (21.2 percent) The government is advising travelers during the Ramadan exodus against using motorbikes when they head back to their hometowns as these two-wheelers are highly prone to accidents The Transportation Ministry predicts that 123.8 million Indonesians are traveling to their hometowns this Ramadan Indonesia will see 25.23 million motorbikes on its roads before and after Eid the biggest holiday for Indonesian Muslims that comes at the end of Ramadan According to Transportation Minister Budi Karya Sumadi travelers should go on the free homecoming trips provided by the government instead of taking the risk of using motorcycles.  “Traveling on motorbikes for your Eid trips is dangerous Motorbikes are the vehicle type that gets involved in traffic accidents the most just behind tourist buses,” Budi said on BTV’s night talk show Obrolan Malam on Tuesday.  “Imagine if you are on the road for 6-8 hours It must be really tiring. Not to mention that you are bringing your family members,” Budi said Indonesians also have many free travel options to pick from Government bodies —starting from the Transportation Ministry and state-owned enterprises to the police force— have their own free homecoming trip programs “There are ferries provided by the Transportation Ministry and the Navy that depart from Jakarta to Semarang and vice versa the vehicles on these free trips are all comfortable We even have air-conditioned buses with dinners included The ferries even play music,” Budi said the government has prepared rest areas for people who insist on traveling by motorbike Motorcyclists can make multiple stops at these rest areas during their homebound journeys Budi also advised the holidaymakers to stop by the tourist destinations along the way do not use motorcycles for your homecoming trips,” Budi said Government data shows that Central Java becomes the most popular destination this upcoming Eid with 32.75 million people expected to head back to the highly populated province, followed by East Java (24.6 million people) The Eid travelers mostly come from East Java (21.2 million people) and Central Java (18.7 million people) The Eid homecoming traffic congestion is forecast to peak on April 20-21 People can save both money and time by going on their homebound journeys a week earlier “We are encouraging people to travel on April 13-17 and trains are offering tons of discounts [for those dates] We expect this can help prevent the massive traffic congestion on April 20-21,” Budi said.
