Abstract

Earthquake source mechanisms are used to determine local geological characteristics and hazard mitigation. There are several approaches to determine the mechanism of earthquake. In this paper, the relative time of the rupture duration is applied to determine rupture directivity. In determining rupture directivity, the Levenberg-Marquardt (LM) method is proposed to solve the inversion problem. To test the reliability of this method, teleseismic data with an epicentral distance of 40o from the Philippine earthquake on 15 December 2019  6.8, which had a good seismic station distribution with a total of 35 stations, is used. Telesismic data from each station is filtered in the range of 0.25 to 1 Hz to obtain an accurate rupture duration. Furthermore, the rupture duration data set was inverted using the LM method to obtain the direction of earthquake rupture. The results obtained by the curve fitting using the LM method had a good agreement between the observed data and the calculated data. From the curve fitting results, the rupture propagated in the NW direction with azimuth 320.60o ± 2.30o, and this had the same results from previous studies. Therefore, from rupture directivity, the actual fault plane of this earthquake was NP1 which had a strike/dip/rake value of 321o/75o/13o, respectively. The results indicate that the Philippines earthquake of 15 December 2019 had the SE-NW fault orientation, which is part of the Cotabato fault system. The implication of this research is for a preliminary study related to the characteristics of earthquake rupture in areas that have a high level of seismicity. Thus, local residents can avoid areas where ruptures propagate when carrying out earthquake mitigation.

Abstract

Basically, polygamy in Islam is permissible. In fact, according to some scholars, the original law for marriage is polygamy, except for those who are afraid of not being fair, then they are permitted to marry one woman. However, some people in Indonesia have different views on polygamy, some consider it normal and some consider it inappropriate for someone who is good and has authority in society. The government neither agrees nor absolutely rejects people's views on polygamy, but they provide difficult conditions for anyone who wants to practice polygamy. If one pays attention to these conditions it is difficult to fulfill, making it almost impossible for a husband to legally practice polygamy according to the law. One of the conditions that is very difficult for a husband who wants to be legally polygamous is to obtain written permission from his wife. In fact, in Islamic law, a husband who wants to practice polygamy is not required to ask permission from his wife. On the other hand, the presence of Islamic sharia actually has a specific purpose. These goals have been compiled by the scholars with the term maqashid sharia. The principles of maqashid sharia are reflected in various matters in Islamic law, including the law on monogamous and polygamous marriages. With the difficulty of procedures and requirements for polygamy in Indonesia, it is feared that it will become an obstacle to achieving maqashid sharia through this polygamy sharia. The researchers are interested in conducting deeper research related to the suitability of polygamy procedures and requirements in Indonesia with the principles of maqashid sharia.

Abstract

Pengelolaan limbah organik rumah tangga masih menjadi tantangan di berbagai wilayah perdesaan Indonesia, termasuk Kabupaten Trenggalek. Rendahnya kesadaran masyarakat dan terbatasnya akses terhadap teknologi tepat guna menyebabkan limbah dapur rumah tangga belum dimanfaatkan secara optimal. Program Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan literasi lingkungan dan keterampilan pengelolaan limbah melalui inovasi komposter dua fungsi, yang mampu menghasilkan kompos padat dan pupuk cair secara simultan. Kegiatan dilaksanakan di Desa Sukorejo, Kecamatan Gandusari, dengan melibatkan 20 ibu rumah tangga dari kelompok PKK. Metode pelaksanaan menggunakan pendekatan edukatif-partisipatif berbasis model DEK SUSI dan Participatory Technology Development (PTD). Evaluasi dilakukan melalui pre–post test, angket, observasi, dan wawancara. Hasil menunjukkan peningkatan pemahaman peserta dari skor rata-rata 2,9 menjadi 3,9, dengan 95% peserta memahami fungsi kompos, 75% menyatakan alat mudah digunakan, dan 85% bersedia bergabung dalam skema penggunaan kolektif. Hambatan utama adalah keterbatasan alat, ruang, dan akses bioaktivator. Program ini terbukti efektif dalam membangun kesadaran dan keterampilan masyarakat terhadap pengelolaan limbah berbasis rumah tangga. Inovasi sederhana ini memiliki potensi untuk direplikasi secara luas guna mendorong transformasi perilaku lingkungan dan ekonomi sirkular lokal.

Abstract

Abstrak Sulawesi Tengah merupakan daerah dengan tingkat seismisitas yang tinggi. Gempa bumi berkekuatan besar sering terjadi baik di daratan atau di lautan. Pada tanggal 12 April 2019 telah terjadi gempa bumi berkekuatan Mw 6,8 mengguncang Banggai Sulawesi Tengah. Penelitian ini dilakukan dengan tujuan menganalisis karakteristik rupture gempa Banggai menggunakan metode Multiple Signal Classification Back Projection. Data yang digunakan dalam penelitian ini merupakan data sekunder yang didapatkan dari IRIS WILBER 3 berupa gelombang seismik dari stasiun array AU dengan jumlah 73 sinyal. Metode yang digunakan dalam penelitian ini dengan teknik pemrosesan array AU berformat .SAC dan data tersebut diolah menggunakan program MUSICBP. Hasil analisis citra rupture beresolusi tinggi mendeskripsikan rupture gempa merambat secara unilateral sepanjang ~40 km/s dari episenter, dengan kecepatan 1,6 km/s dan durasi sebesar 25 Sekon. Hasil dari pencitraan rupture menunjukkan gempa bumi yang terjadi di Banggai pada 12 April 2019 disebabkan oleh aktivitas sesar Peleng di Pulau Sulawesi Tengah dengan rupture merambat ke arah Timur Laut dengan mekanisme Strike-Slip. Hasil akurasi MUSICBP yang didapatkan untuk mengetahui karakteristik rupture cukup akurat, yaitu dengan memvalidasi melalui IRIS WILBER 3. Ada sedikit perbedaan arah dengan penelitian terdahulu, akan tetapi lokasi penyebab nya menuju sesar yang sama, yaitu sesar Peleng.   Abstract Central Sulawesi is a region with a high level of seismicity. Large-magnitude earthquakes frequently occur both on land and at sea. On April 12, 2019, an earthquake with a magnitude of Mw 6.8 struck Banggai, Central Sulawesi. This study aims to analyze the rupture characteristics of the Banggai earthquake using the Multiple Signal Classification Back Projection (MUSICBP) method. The data used in this study are secondary data obtained from IRIS WILBER 3, consisting of seismic waveforms recorded by the AU array station, totaling 73 signals. The method employed in this research involved processing the AU array data in .SAC format, which were analyzed using the MUSICBP program. The results of the high-resolution rupture imaging describe that the rupture propagated unilaterally along approximately 40 km from the epicenter, at a speed of 1.6 km/s, with a duration of about 25 seconds. The rupture imaging results indicate that the earthquake that occurred in Banggai on April 12, 2019, was caused by the activity of the Peleng Fault in Central Sulawesi, with the rupture propagating toward the northeast and exhibiting a strike-slip mechanism. The MUSICBP analysis result were obtained to understand the characteristics of the fracture, specifically through validation using IRIS Wilber 3. There were slight differences between the direction and previous studies, but the location of the cause was the same, Fault Peleng.

Abstract

The STEAM (Science, Technology, Engineering, Arts, and Mathematics) approach is a new form of teaching that places students in real-world situations around them by following the concept of interdisciplinary teaching. STEAM is highly relevant in supporting students' 21st-century skills. As is well known, 21st-century skills encourage students' critical thinking, communication, collaboration, innovation, and creativity. In physics learning, it is not uncommon for students to have difficulty understanding the subject. Teachers, as learning facilitators, are expected to be able to integrate STEAM into physics education. Teachers must have the skills to develop learning tools. Through research using the SLR method, this study aims to investigate the importance of teachers' competencies in implementing project-based STEAM learning in physics education. Project-based learning emphasizes collaborative learning activities among heterogeneous groups of students. The analysis results show that the implementation of the STEAM approach in learning is still limited. Physics teachers are important agents in equipping students with the necessary physics knowledge and scientific investigation skills. Therefore, physics teachers need support in improving their understanding of STEAM. In learning activities involving project-based STEAM, it is known that it can increase students' creativity and innovation in problem solving.

Abstract

Seismic activity in Malang City is very high due to tectonic dynamics in the subduction zone between the Indian-Australian and Eurasian plates and the active local faultsm, including the northeast-southwest trending Watukosek Fault, and the east-west fault around the Pasuruan Fault, which have the potential to cause damaging ground shaking in Malang City. The BMKG also recorded an earthquake with a magnitude of 4.5 Mw on March 16, 2025. Based on these events, this study was conducted to analyze the vulnerability of Malang City, East Java, using the Horizontal-Vertical Spectral Ratio (HVSR) method by integrating the parameters of natural frequency (f0), amplification (Ag), soil vulnerability index (Kg), and Ground Shear-Strain (γ).  A total of 19 points were processed using Geopsy software to obtain the HVSR curve and obtain the f₀ and Ag values, while Kg and γ were obtained from processing the HVSR parameters and then mapped through spatial interpolation in ArcGIS. The results of data processing and analysis show that several points in Malang City have f0 1.448 - 9.938 Hz with amplification 1.704 - 6.639 and soil vulnerability index values 0.383 - 14.871, as well as shear strain values up to 0.009. Zones are mainly concentrated by high amplification and vulnerability are mainly concentrated in the northern part of Kedungkandang District, the eastern part of Blimbing District, and parts of Lowokwaru District, which are dominated by higher frequencies with low amplification, as well as the western part of Sukun District, indicating a high level of earthquake risk.  While previous studies primarily utilized only utilized natural frequencies and amplification, whereas this study offers HVSR-based microzonation by integrating dynamic soil parameters (f₀, Ag, Kg, and γ).

Abstract

This study investigates deep-focus intraslab deformation offshore Northern Java by analyzing two recent major earthquakes: 6 July 2020 (  6.67) and 14 April 2023 (  6.96), occurring at centroid depths of ~500–600 km. The objective is to constrain the source mechanisms and infer the prevailing deformation regime within the subducting Indo-Australian slab. We perform time-domain moment tensor (TDMT) inversion of broadband waveforms (GE/GEOFON network) using MTTime, with standard preprocessing (instrument correction and band-pass filtering) and Green’s functions computed from the 1-D ak135 velocity model. Centroid depth is refined via a grid search that maximizes waveform variance reduction (VR). The preferred solutions show good waveform agreement (VR = 82.0% for the 2020 event and 71.6% for the 2023 event) and are consistent with Global CMT solutions (Kagan angles = 7.04° and 6.31°, respectively). Both earthquakes exhibit oblique normal faulting with a persistent dextral strike-slip component, indicating a dominantly extensional stress regime at depth, likely driven by slab pull/gravitational sinking, while the consistent trench-parallel shear suggests more complex internal slab deformation. These results provide quantitative constraints on deep intraslab kinematics beneath Java and motivate expanded event sampling for a more robust regional interpretation.

Abstract

Kekerasan dalam rumah tangga (KDRT) merupakan pelanggaran hak asasi manusia yang bertentangan dengan prinsip mawaddah wa rahmah dalam pernikahan. Fenomena istri korban KDRT yang memilih bertahan demi kepentingan anak menimbulkan konflik antara perlindungan diri korban dan keutuhan keluarga. Kondisi ini memerlukan analisis kesesuaiannya dengan maqashid syari'ah, khususnya dalam penimbangan maslahah dan mafsadah. Penelitian ini bertujuan menganalisis pengalaman resiliensi istri korban KDRT yang bertahan demi anak, serta mengevaluasi pertimbangan maslahah dan mafsadah yang melatarbelakangi keputusan tersebut berdasarkan perspektif maqashid syari'ah. Penelitian ini menggunakan pendekatan kualitatif dengan metode fenomenologi yang diintegrasikan dengan analisis normatif maqashid syari'ah, data diperoleh melalui wawancara mendalam terhadap tiga informan istri korban KDRT dan satu informan anak korban yang dipilih secara purposive sampling. Hasil penelitian menunjukkan resiliensi dibangun melalui strategi koping defensif yang dibentuk oleh realitas sosial dan religius. Keputusan bertahan menimbulkan konflik antara maslahah hajiyyah zhanniyyah dengan mafsadah dharuriyyah qath'iyyah berupa kerusakan fisik-psikologis ibu dan anak termasuk gangguan attachment dan siklus kekerasan lintas generasi. Berdasarkan kaidah dar'u al-mafasid muqaddam 'ala jalbi al-masalih, maqashid syariah memprioritaskan hifz al-nafs sehingga resiliensi dalam konteks KDRT tidak dianjurkan secara normatif.
