Abstract

Estuaries provide valuable ecosystem services, but they are also subject to environmental pressures due to high anthropogenic activities. The diversity and abundance of Polychaete can be used as indicators of the health of the Kapuas estuary, but supporting data are currently lacking. The objective of this research is to assess the quality of the Kapuas estuary through a Polychaete community approach. The study employed a survey method by selecting ten Polychaete sampling points based on their surrounding environmental conditions. Samples were collected from each point using a Petite Ponar grab, filtered, sorted, and grouped by family. The Polychaete specimens were identified up to the genus level. The data were analyzed descriptively. A total of 108 Polychaete individuals were found, comprising nine genera and seven families. The highest abundance was observed in the genera Capitella (Capitellidae) and Sternaspis (Sternaspidae), with 778 ind.m-2and 667 ind.m-2, respectively. The diversity of Polychaete in the Kapuas estuary was classified as low, with diversity index ranging from 0.5 to 1.21. The high abundance, low diversity, and presence of indicator genera of organic pollutants such as Capitella indicate that the Kapuas estuary is affected by organic contamination

Abstract

Ikan tembakul (Boleophthalmus boddarti) ialah ikan yang seringkali dijumpai pada wilayah mangrove, ikan yang mampu berjalan di darat, serta memijah pada lubang lumpur kawasan persembunyian.  Ikan ini dimanfaatkan sebagai bahan pangan, obat tradisional maupun umpan untuk memancing, tetapi masih banyak dari sebagian masyarakat yang tidak mengetahui manfaatnya. Penurunan kualitas lingkungan di Kawasan Wisata Religi Kong Khew Pak Kung Kecamatan Sungai Pinyuh akibat penumpukan sampah diduga dapat menurunkan populasi ikan tembakul. Tujuan penelitian ini adalah untuk mengetahui karakteristik reproduksi ikan tembakul yang meliputi nisbah kelamin, faktor kondisi, Tingkat Kematangan Gonad (TKG), Indeks Kematangan Gonad (IKG), fekunditas dan diameter telur. Penelitian ini dilakukan mulai Desember 2022 hingga Februari 2023 dengan metode random sampling menggunakan alat tangkap jaring dengan panjang 10 m dan lebar mata jaring 1/1,5 inch. Data dianalisis secara deskriptif. Nisbah kelamin didapatkan 1:1 dengan dominansi ikan muda dengan Tingkat Kematangan Gonad (I-II). Indeks kematangan gonad (IKG) jantan rata-rata berkisar 0,07-1,93% dan nilai IKG betina rata-rata berkisar 0,06-5,76%. Fekunditas sebanyak 42.212-80.198 butir dengan diameter telur antara 0,15-0,60 mm dan termasuk dalam kelompok pemijahan serempak (total spawner).

Abstract

The Earless monitor (Lanthanotus borneensis Steindachner, 1878) is a rare and endemic species of lizard to the island of Borneo. Individuals of this species were often culled to supply the international pet market and have been kept in captivities, also in the northern temperate areas. This study aimed to describe the daily activities of L. borneensis at the reptile house of Museum Zoologicum Bogoriense (MZB), a live animal research facility of the former Indonesian Institute of Sciences (LIPI) - now merged into BRIN. Focal animal sampling was used to observe L. borneensis behavior for two hours per individual in the morning (09:00–11:00) and afternoon (15:15–17:15) with the assistance of surveillance cameras (CCTV), resulting in a total observation time of 16 hours per individual per two months. The observations of 10 individuals of L. borneensis showed that they were more inactive in the morning, with a tendency to be more active and feeding in the afternoon. During inactivity, lizards remained motionless in the bamboo; when active, they were moving in water and foraging.

Abstract

Taxes are one of the government's largest sources of funding. The automotive industry is one of the sectors that generates the largest amount of tax. Every vehicle and electronic product is subject to VAT, and those included in the luxury goods category will be subject to PPNBM. The focus of this study is the effect of taxes on consumer purchasing power. For this writing, Systematic Literature Review (SLR) was used; SLR reviews articles in a systematic and planned manner, increasing the depth of examination related to VAT and PPNBM. The research results show that, simultaneously, the variables VAT (X1) and PPnBM (X2) influence consumer purchasing power (Y). VAT (X1) has a significant positive effect on buyers' desire to buy a luxury good. The PPnBM variable (X2) has a significant influence on consumer purchasing power for luxury goods. When the tax imposed is higher, of course, this means that the luxury goods owner will gain social status and prestige. This shows that people have the ability and are willing to pay taxes on luxury goods so that they can be respected for having high-quality products.

Abstract

The Indonesian Banking Architecture (IBA) is a strategic policy launched by Bank Indonesia in 2004 to build a healthy, efficient, and resilient national banking system in the face of global economic dynamics. Over the past two decades, IBA has been a guideline for transforming Indonesia's banking sector. The program is designed to strengthen the national banking structure through policies, including banking consolidation, capital consolidation, technological infrastructure development, and improved governance and risk management. As a result of this policy, the quantity of banks in Indonesia has decreased, which is in line with the strengthening of capital quality, thus creating a more solid and integrated banking system. This article explores the benefits of IBA’s implementation for the banking industry in the last two decades. This study utilizes secondary data from related academic research.

Abstract

Urgensi penelitrian ini adalah mengingat bahwa negara Indonesia Masyarakat yang pluralistic, baik suku maupun agamanya. Pluralistik  agama bisa dilihat dari agama yang diakui negara terdapat 5 yaitu agama Islam, katholik, Kristen, Hindu, Budha dan Kong huchu. Setiap agama selalu meyakini bahwa agamanya yang paling benar. Klaim kebenaran juga dimiliki agama Islam. selain klaim kebenaran, Islam memiliki Sejarah tersendiri dibandingi agama lainnya. Tidak bisa dipungkiri bahwa muslim memiliki andil besar dalam kemerdekaan Indonesia. Sehingga tidak heran Sebagian umat Islam menginginkan Indonesia menjadi negara islam (Islamic state). Fenomena di atas tentu bisa menjadi ancaman bagi persatuan bangsa Indonesia. Padahal negara Indonesia yang berasaskan Pancasila telah mengakomodasi kepentingan semua agama. Khususnya agama Islam yang telah mengakomodasi tujuan syari’ah. Sehingga harapannya dengan konsep negara hukum pencasila berbasis maqasidu shari’ah bisa meredamkan keinginan untuk mendirikan negara islam. Tujuan Penelitian ini adalah : 1) Bagaimana konsep negara hukum Pnacasila berbasis maqasidu shari’ah, 2) bagaimana moderasi beragama dalam konsep negara hukum Pancasila berbasis maqasidu Shari’ah. Metode  penelitian ini  kepustakaan dengan pendekatan kualitatif. Metode penelitian yang digunakan pada penelitian ini adalah analisis isi. Analisi isi merupakan suatu studi yang menggabungkan hasil banyak studi orisinal, sistematis, dan terencana. Metode ini dilaksanakan melalui lima tahap, yaitu (1) Pengumpulan data; (2) Pertanyaan penelitian; (3) Hipotesis yang akan diuji; (4) Penyajian data dan (5) Penarikan kesimpulan. Sumber data dalam artikel ini adalah jurnal dan buku. Luaran yang ditargetkan dalam penelitian ini adalah publikasi hasil penelitian pada jurnal internasional bereputasi yang terindek Scopus. Indonesia is a pluralistic state with various ethnic groups and religions. Even so, it cannot be denied that Muslims have a great role in claiming Indonesian independence. Thus, it is no wonder that part of the Muslim community wishes Indonesia to become an Islamic state, even though it is based on Pancasila, which accommodates the interests of all religions. This condition certainly becomes a threat to the unity of the Indonesian nation. The Pancasila legal state concept based on maqasid sharia is hoped to dampen the desire to establish an Islamic state. This research aims to: (1) analyze the Pancasila legal state concept based on maqasid sharia, and (2) analyze religious moderation in the Pancasila legal state concept, based on maqasid sharia. This was library research which employed the qualitative approach. The research method used in this study was the content analysis, which was a study which combines various original, systematic, and planned studies. Research results showed that religious moderation in Indonesian diversity is crucial. One of the reasons is that Indonesia is a plural country both in terms of ethnic groups and religions. A religious understanding that is exclusive may be directed to religious moderation. A radical religious thought regards Pancasila as violating Islamic teachings. This paper shows that the Pancasila legal state concept is according to maqasid sharia as it accommodates the protection of religion, the protection of lives, the protection of offspring, the protection of the mind, and the protection of wealth.

Abstract

The Community Service Program (Kuliah Kerja Nyata / KKN) serves as a form of student engagement aimed at contributing tangible benefits to society through various work programs tailored to local community needs. The KKN program implemented in Danawinangun Village, Klangenan Sub-district, primarily focused on enhancing literacy, as well as addressing environmental, social, and health aspects. The activity employed a participatory method, emphasizing the active involvement of the community, local government, and students throughout the stages of planning, implementation, and evaluation. Through this approach, students and community members collaboratively designed and executed several programs, including literacy activities in elementary schools, the establishment of reading corners, shared read-aloud sessions, and the creation of simple waste management facilities. In addition, students revitalized the “Clean Friday” initiative to promote a healthy and sustainable village environment. The results of the program indicate an improvement in children’s reading interest, increased community participation in maintaining cleanliness, and the establishment of positive collaboration between students, village authorities, and residents. Despite certain challenges, such as limited facilities and uneven participation, alternative solutions were implemented through persuasive approaches and the utilization of local potential. Therefore, this participatory-based KKN activity not only provided meaningful experiential learning for students but also generated a positive and sustainable impact on the community in the fields of education, environment, and social development.ABSTRAKKuliah Kerja Nyata (KKN) merupakan salah satu bentuk kegiatan pengabdian mahasiswa kepada masyarakat yang bertujuan untuk memberikan kontribusi nyata melalui berbagai program kerja sesuai dengan kebutuhan lokal. Kegiatan KKN yang dilaksanakan di Desa Danawinangun, Kecamatan Klangenan, berfokus pada peningkatan literasi, serta aspek lingkungan, sosial, dan kesehatan.
