Abstract

East Java Province is geographically close to the Eurasian and Indo-Australian Plate subduction zones, resulting in frequent earthquakes East Java Province has a high population density, so it is very risky if disaster occurs. One preventive solution to reduce this impact is estimating damage when an earthquake occurs. The purpose of this study was to determine the best modeling of damages due to earthquakes in East Java Province, using the amount of house damage as a response variable, while depth of the epicenter and the strength of the earthquake as predictor variables. It is suspected that there is a spatial dependency effect in this case, so the solution is to use regression with an area approach, namely the Spatial Durbin Model (SDM). The amount of house damage is collected from BNPB, the epicenter and the magnitude of earthquake collected from BMKG in 2021. The result shows that SDM is good at explaining the dependency relationship between response and predictor variables. The significant predictor variables are the depth of epicenter and the strength of the earthquake. It is meaning that the magnitude and the depth of the epicenter of the earthquake in an area have an impact on other adjacent areas. There is a relationship between the amount of house damage in one area and other adjacent areas. The Regency will have a high number of damaged houses if it is adjacent to a Regency that has a high number of damaged houses

Abstract

The Omnibus Law is a recently enacted legislation that has been implemented within the regulatory framework of Indonesia. This legal framework, often denoted as the Universal Sweeping Law, consolidates multiple legal norms into a singular regulation. The Omnibus law encompasses a total of 11 distinct clusters, one of which pertains specifically to labor regulations. Nevertheless, the Omnibus law has elicited diverse reactions among the Indonesian populace, particularly on the Twitter platform. The researchers employed scraping techniques to extract tweets from Twitter users. A total of 3067 data points were collected during the period from March 20, 2022 to May 20, 2022. The data were subsequently categorized into positive, negative, and neutral sentiments. They were then assigned weights and classified using the Suport Vector Machine (SVM) method. The objective was to identify the public's sentiments towards the Omnibus law and evaluate the accuracy of the Support Vector Machine (SVM) method. The accuracy of the SVM algorithm with a linear kernel is found to be 97.05% based on its classification performance. There is a greater level of public concern and attention directed towards positive responses in relation to the Omnibus law, as opposed to negative responses. The positive responses encompassed the provision of favorable legislation to assist young entrepreneurs, whereas the negative responses pertained to concerns regarding persistently low wages for workers, despite the implementation of the Omnibus Law.

Abstract

Abstract: This article discusses the implementation of marriage isbat due to polygamy after the enactment of the Supreme Court Circular (SEMA) Number 3 of 2018. In the SEMA, the Supreme Court did not permit to ratify polygamous marriage isbat, but the decision of the Mataram Religious Court Number 634/Pdt.G /2018/PA.Mtr granted the application for polygamous marriage isbat. This paper aims to determine the decidendi ratio in the acceptance of the isbat of polygamous marriages. This research applies a statutory approach in a case. This study concludes that the Panel of Judges granted the case in decision Number 634 by ignoring SEMA Number 3 of 2018. Realizing justice and benefit for Siri's wife as heirs so that she can disburse her husband's pension TASPEN fund is seen as more beneficial by the Panel of Judges. In this way, her husband's pension TASPEN funds can be used to meet the living needs of the Petitioner and his family. The implication is that the decision can be called a legal breakthrough from the point of view of progressive law because it is based on the benefit that is considered more significant than following the material law of polygamous marriage. Abstrak: Artikel ini membahas pelaksanaan isbat nikah akibat poligami setelah berlakunya Surat Edaran Mahkamah Agung (SEMA) Nomor 3 Tahun 2018. Dalam SEMA Nomor 3 Tahun 2018, Mahkamah Agung tidak lagi memberikan izin untuk pengesahan isbat nikah poligami, namun putusan No.634/Pdt.G/2018/PA.Mtr mengabulkan permohonan isbat nikah poligami. Tujuan penulisan ini untuk mengetahui ratio decidendi dalam pengabulan isbat nikah poligami, apakah putusan catat hukum atau sebagai terobosan hukum. Penelitian ini merupakan kombinasi penelitian hukum normatif dan penelitian hukum empiris dengan pendekatan perundang-undangan (Statue Approach) dan pendekatan kasus (Case Approach). Penelitian dilakukan meliputi penelitian kepustakaan dan penelitian lapangan. Hasil penulisan ini adalah putusan perkara Nomor 634/Pdt.G/2018/PA.Mtr dikabulkan oleh Majelis Hakim dengan mengesampingkan SEMA Nomor 3 Tahun 2018. Putusan tersebut termasuk sebuah terobosan hukum dengan mencerminkan hukum progesif dengan mendasarkan kemaslahatan yang lebih utama ketimbang mengikuti hukum materiil yang mengatur tentang perkawinan poligami. Merealisasikan rasa keadilan dan kemaslahatan bagi isteri siri kedua sebagai ahli waris agar dapat mencairkan dana taspen pensiunan suami dipandang lebih maslahat oleh Majelis hakim. Sebab, dana taspen pensiunan suaminya tersebut dapat digunakan untuk mencukupi kebutuhan hidup Pemohon beserta keluarganya.

Abstract

Short text topic modeling remains challenging due to data sparsity, limited word co-occurrences, and unstable clustering results, particularly for Indonesian texts. This study proposes an improved BERTopic framework that integrates IndoBERT embeddings, best match 25 (BM25)-based topic representation, and balanced iterative reducing and clustering using hierarchies (BIRCH) clustering to address these issues. IndoBERT generates contextual embeddings adapted to Indonesian linguistic features, and BM25 weighting improves keyword relevance by considering document length and term saturation. BIRCH clustering minimizes outliers by assigning most documents to valid clusters, which enhances data utilization and topic stability. Experiments on Indonesian datasets from X (formerly Twitter), Google Reviews, and YouTube demonstrate that the proposed approach consistently achieves higher topic coherence. The proposed method yields stable topic diversity values between 0.91 and 0.94, maintains embedding density from 0.60 to 0.66, and achieves intra-topic similarity between 0.39 and 0.41 across increasing dataset sizes. The proposed framework successfully reduces outlier proportions to 1-5%, which significantly outperforms standard BERTopic and K-Means. Furthermore, the model maintains stable topic counts as the data volume grows, confirming robustness and scalability for sparse short text modeling. Overall, integrating IndoBERT, BM25, and BIRCH provides a more coherent, stable, and effective solution for Indonesian short text topic modeling.

Abstract

After the Arab Spring, which was distinguished by the development of liberalism, Tunisia's personal status law became more progressive. This liberalism is exemplified by the enactment of a law permitting Muslim women to marry non-Muslim men. Tunisia's efforts to liberalize Islamic family law appear to be impeded, however, by the rejection of a proposal to change the law on inheritance equality between men and women. The purpose of this study is to examine the liberalism of Islamic family law in Tunisia. Using information media such as news, articles, and other sources, the research utilizes a descriptive-qualitative strategy with a theoretical and fact-based approach. This article argues that there are at least three reasons for Tunisia's modest liberalization of Islamic family law 1) Avoiding confrontations with secularists as much as possible. 2) Learning from the failure of the 2014 parliamentary general election, which revealed that Tunisians prefer non-religious parties. 3) The idealistic and pragmatic reasons of Ennahdha members.Pasca terjadinya Arab Spring, sistem perpolitikan di Tunisia menjadi lebih demokratis menyebabkan liberalisme pemikiran semakin menguat. Liberalisme tersebut ditunjukan dengan disahkanya undang-undang pernikahan wanita muslimah dengan laki-laki non-muslim. Namun upaya liberalisme hukum keluarga Islam Tunisia tampaknya masih terbatas dengan ditolaknya penyeruan amandemen undang-undang persamaan hukum waris antara laki-laki dan perempuan. Penelitian artikel ini adalah penelitian pustaka (library research). Metode yang penulis gunakan adalah metode deskriptif-kualitatifdengan pendekatan teoritis dan fakta melalui media informasi baik berita, artikel, maupun sumber lainya. Hasil penelitian menyimpulkan bahwa terjadinya liberalisme terbatas hukum keluarga Islam di Tunisia disebabkan tiga alasan. 1) Menghindari ketegangan dengan kaum sekuler 2) Belajar dari pengalaman kekalahan dalam pemilihan umum legislatif pada tahun 2014 yang menujukan masyarakat Tunisia cenderung memilih partai yang tidak berbasis agama, 3) Motif idealis dan pragmatis anggota partai Ennahdha].

Abstract

A wide range of data is now easily accessible via the microblogging service Twitter thanks to the rapid advancement of technology. The Bjorka controversy, one of the most talked-about topics right now, has generated numerous comments from the general public and thus has risen to the top. The Bjorka phenomenon is an obvious example of cybercrime, with a sharp uptick in incidents occurring in Indonesia during the COVID-19 pandemic. Sentiment analysis employing the Support Vector Machine technique allows for the statistical analysis of public opinion about Bjorka as it appears on the Twitter social network. Latent Dirichlet Allocation (LDA) will be used to analyze the sentiment analysis with SVM results, which have been separated into positive and negative sentiments. In this study, using LDA for sentiment analysis resulted in an accuracy of 89.5%. Dismantling government data, including personal data and government crimes, was the most positively predicted topic, with 75.2% of all predictions leaning in that direction. It is hoped that the government will be able to use the information gleaned from this study to better understand the public’s perspective and the trust deficits that need to be addressed
