Abstract

Perairan danau dan sungai Poso sudah lama diketahui sebagai daerah penangkapan ikan sidat. Ikan sidat termasuk famili Anguillidae merupakan ikan katadromus yaitu ikan yang hidup di perairan tawar (sungai/danau), bermigrasi ke laut untuk melakukan pemijahan dan setelah itu kembali lagi ke perairan tawar untuk melanjutkan siklus hidupnya. Benih ( glass eel/elver) sidat di aliran Sungai Poso sendiri bergerak dari Muara Poso, kemudian bermigrasi anadromus untuk sampai ke perairan tawar melewati beberapa wilayah sungai seperti Sungai Pandiri, Sulewana menuju Rawa Tentena dan kemudian berakhir di Danau Poso. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik perairan yang dilalui fase-fase ikan sidat. Penelitian karakteristik perairan ikan sidat telah dilakukan pada bulan Maret, Mei, Juli dan September 2012 dengan metode survei berstrata. Dari pengamatan diperoleh hasil bahwa karakteristik dari lima stasiun pengamatan hampir sama, dimana karakteristik dasar perairannya berbatu dan berpasir, vegetasi yang tumbuh di sekitar sungai juga sama seperti pohon-pohon besar dan alang-alang. Kondisi kualitas perairan di aliran Sungai  Poso yang dilewati oleh fase-fase ikan sidat juga masih mendukung untuk kehidupan sidat.

Abstract

Water hyacinth {Eichhornia crassipes) in Lake Limboto was covering the area about 40 to 60% in 2008. It caused a lot of problems on water transportation, fishing activities, reducing water quantity and quality. To manage the number of water hyacinth population, biological control use omnivorous species and such as grasss carp (Ctenopharingodon idella) is a promosing alternative. In this study, effect of different stocking density of grass carp on the population of water hyacinth was observed. The result showed that 200 fish was the most effective compare to other stocking density and enabled to reducing the covering area up to 10 to 20%.

Abstract

Embung or retention basin is one of the surface water sources in the form of artificial lake obtained from harvesting the rain and surface water. East Nusa Tenggara (NTT) Province has built 963 retention basins and three dams which are used mainly for irrigation, plantation, and livestock, while for fisheries it has not been developed optimally. The development of capture fisheries through the stocking of fish seeds is one of the efforts to optimize the utilization and management of water bodies. The failure of fish stockings in several water bodies in NTT is thought to be caused by lack of scientific studies before the stockings. Therefore, the purpose of this research was to determine the potential of fisheries production and the optimal number of seeds for the development of capture fisheries in the retention basins of NTT. The research was conducted in September 2016. Water samples were taken at a depth of 0.5 m from the surface using the Kemmerer water sampler. Secondary data which included fish growth parameters were obtained from literature, while seed production and morphological characteristics of water bodies were obtained from relevant institutions. The results showed that Embung Tulamalae and Oelpuah were eutrophic, while Embung Haekrit and Haliwen were oligotrophic. The average potential of fisheries production based on MEIcond ranged 41.3−68.7 kg/ha/year with an average of 52.8 kg/ha/year, while based on chlorophyll a content ranged 29.8‒55.8 kg/ha/year with an average of 43.6 kg/ha/year. Estimation of seed requirements for restocking in the context of developing capture fisheries ranged from 1,000 to 48,600 individuals/year. Based on the water quality and economic values obtained, embung at the research locations are feasible for fish stocking in the capture fisheries development.

Abstract

An anchored house, which stands above seawater, is common in North Jayapura and South Jayapura. Wooden foundations support these houses. People frequently contract waterborne diseases when they use or consume water that is contaminated with pathogenic bacteria, such as coliform bacteria from human feces. In these areas, high levels of coliform bacteria can have an impact on water quality and public health. This study looks into how anchored houses affect total coliform contamination, the number of cases of waterborne disease (WBD), and the link between demographic factors, water quality, and WBD cases. We use the Most Probable Number (MPN) method to detect total coliform bacteria in marine waters. It consists of an initial test using LBS and LBD media for prediction, followed by a second test using Brilliant Green Lactose Bile Broth (BGLBB) media for confirmation. We also use observation and interview methods to identify WBD cases in anchored housing in North Jayapura and South Jayapura districts. North Jayapura has the highest coliform bacteria contamination in marine waters, with an average of 25.7 MPN/100 mL. Similarly, the highest contamination in clean water is in North Jayapura, averaging around 347.6 MPN/100 mL. The demographic characteristics in both districts are mostly men aged 18–65 years with high school education and occupations such as housewives and fishermen. The South Jayapura sub-district has the highest incidence of WBD. Anchored houses have no significant effect on water quality or the incidence of WBD, and there is no correlation between water quality and WBD incidence.

Abstract

This study elucidates the factors that have driven the emergence of Salafism in rural Java, including the individual actors, the global Salafi movement, and the connections established amongst Islamic organizations since the fall of the New Order. This study emphasizes that the Salafi movement has not been purely religious in rural Java, but rather served to provide members with economic and political salvation. Diverse economic and political contestations have occurred within the Salafi movement as actors within the movement have established connections with individuals who share their vision and political ideology. This article concludes that the Salafi movement may be considered a form of political Islam, wherein individuals contest public spaces through public piety, economic activities, and political approaches. Data for this study were collected through field research, interviews with informants, and a review of the literature. A political sociology approach was used to analyze the connections between village actors, the spread of Salafism, and the political and economic issues faced by religious organizations.

Abstract

Penelitian ini bertujuan untuk memetakan persebaran ikan pirik secara spasial dan temporal serta menganalisis faktor-faktor yang memengaruhi persebarannya pada sungai-sungai di DAS Maros dan di DAS Walanae Cenranae. Pengambilan sampel dilakukan dari bulan Mei 2018 hingga April 2019. Penelitian dilakukan di 19 stasiun pengambilan sampel, terdiri atas 6 stasiun di DAS Maros dan 13 Stasiun di DAS Walanae Cenranae, Provinsi Sulawesi Selatan. Penangkapan ikan pirik menggunakan electric shocker (12 V, 9 A) dan jaring lempar. Ikan contoh diawetkan dalam larutan formalin 10% dan alkohol 70 %.  Pengukuran parameter fisik kimiawi perairan meliputi kedalaman, arus, suhu, pH, oksigen terlarut, padatan tersuspensi total (TSS), padatan terlarut total (TDS) dan konduktivitas. Hasil penelitian menujukkan persebaran spasial ikan pirik pada sungai-sungai di DAS Maros terdiri atas empat stasiun yaitu M1 (S. Pattunuang), M2 (S. Bantimurung), M3 (S. Pucak), M4 (S. Batu Bassi) dan pada sungai-sungai di DAS Walanae Cenranae terdiri atas  delapan stasiun yaitu W1 (S. Camba), W2 (S. Sanrego), W4 (S. Batu-Batu), W5 (S. Sawae), W6 (S. Pising), W7 (S. Mutiara), W8 (S. Assanae) dan W10 (S. Ompo). Persebaran temporal ikan pirik terdiri atas tiga kategori persebaran yaitu ikan pirik yang ditemukan pada semua musim, ikan pirik hanya ditemukan ketika musim tertentu, dan ikan pirik yang tidak ditemukan pada semua musim. Jumlah ikan pirik ditemukan terbanyak pada musim penghujan, diikuti awal musim penghujan, kemudian awal musim kemarau dan terendah pada musim kemarau.  Jumlah ikan pirik yang tertangkap dipengaruhi oleh karakteristik fisik kimiawi perairan yaitu kecerahan, oksigen terlarut dan arus.

Abstract

The phenomenon of mosque fundraising on highways represents an established social practice in Indonesian society, particularly in Bangkalan Regency. This practice creates a unique dynamic between religious legitimacy and social norms that warrants comprehensive examination. This study aims to analyze the practice of mosque fundraising on Bangkalan Regency highways from the perspective of Islamic legal sociology, focusing on the interaction between religious and social norms that shape this practice. Employing a qualitative approach with field research methods, data were collected through in-depth interviews, observation, and documentation. The findings indicate that mosque fundraising practices on highways receive support from local religious leaders despite contradicting the Indonesian Ulema Council (MUI) fatwa. This support creates strong social acceptance, making it an integral part of local tradition that is difficult to modify. However, this practice raises challenges related to road user safety and trustworthy fund management. It can be concluded that the practice of mosque fundraising on Bangkalan Regency highways is formed through complex interactions between religious and social norms that mutually legitimize each other. Better management is needed to avoid negative impacts on society and increase awareness of public safety.

Abstract

This study examines the evolution of political Islam in Indonesia during the presidencies of Susilo Bambang Yudhoyono (SBY) and Joko Widodo (Jokowi), focusing on the shift from accommodation to repression. During the SBY era (2004-2014), the government adopted an accommodative approach towards Islamic groups, engaging moderate organizations such as Nahdlatul Ulama and Muhammadiyah as strategic partners in maintaining social stability. However, conservative groups began to challenge the democratization agenda. In contrast, Jokowi's administration (2014-2024) has faced increasingly complex challenges due to the rise of Islamic populism and identity politics, as exemplified by Aksi Bela Islam (ABI) 212. In response, Jokowi implemented more assertive measures, such as banning the HTI and FPI, to safeguard national stability and prevent radicalization. This study employs a qualitative descriptive approach and a literature review to analyze the dynamics of political Islam's rise and transformation during these two periods. The findings reveal that SBY's accommodative policies created relative stability but compromised pluralism, while Jokowi's repressive approach exacerbated political polarization. The study concludes that the evolution of political Islam reflects a dynamic process in which the state must balance Islamic aspirations, democratic commitments, and the need for stability amidst the increasing challenges to pluralism. Understanding these shifts is essential for comprehending the complex relationship between Islam, democracy, and national stability in Indonesia

Abstract

Dewasa ini pandemi Covid-19 di Indonesia melumpuhkan berbagai sektor penting, seperti kesehatan, pariwisata, perekonomian, dan sebagainya. Kondisi tersebut dimanfaatkan oleh oknum tertentu untuk meraup keuntungan melalui sebuah aplikasi yakni VTube. Aplikasi VTube dianggap sebagai solusi yang tepat bagi sebagian kalangan masyarakat untuk mengatasi perekonomian dalam bentuk investasi. VTube dengan system money game menjalankan fungsinya dengan mengimplementasikan skema ponzi/ skema piramida yang hanya menguntungkan pihak pertama dan merugikan pihak lain. Penelitian ini dimaksudkan guna meninjau lebih jauh terkait sistem pelaksanaan dari aplikasi VTube menurut fikih Muamalah. Melalui penyebaran kuisener dan wawancara, data diperoleh dan dianalisis. Hasilnya, mekanisme sistem money game dapat merugikan pengguna baik dalam hal moril maupun materiil karena keuntungan yang lebih besar akan diperoleh perusahaan. Hal ini dapat dilihat ketika dalam sistemnya aplikasi ini terdapat ketidakjelasan, artinya dalam aplikasi VTube ditemukan unsur-unsur yang dilarang dalam Fikih Muamalah seperti maysir, gharar, ighra’ dan kadzib. Oleh karena itu, aplikasi VTube merupakan aplikasi yang dilarang karena didalamnya melanggar unsur dalam Fikih Muamalah. Hal ini selaras dengan pendapat Imam Syafii yang mengharamkan praktik jual-beli ghaib. Kata Kunci: VTube, Money Game, Fikih Muamalah Currently, the Covid-19 pandemic in Indonesia has paralyzed various important sectors, such as health, tourism, the economy, and so on. This condition is used by certain individuals to reap profits through an application, namely VTube. The VTube application is considered the right solution for some people to overcome the economy in the form of investment. VTube with a money game system performs its function by implementing a ponzi scheme/pyramid scheme that only benefits the first party and harms the other party. This study is intended to further review the implementation system of the VTube application according to Muamalah fiqh. Through the distribution of questionnaires and interviews, data was obtained and analyzed. As a result, the mechanism of the money game system can harm users both morally and materially because the company will get bigger profits. This can be seen when the system in this application is unclear, meaning that in the VTube application elements that are prohibited in Muamalah fiqh such as maysir, gharar, ighra ‘and kadzib are found. Therefore, the VTube application is an application that is prohibited because it violates elements in the Fiqh of Muamalah. This is in line with the opinion of Imam Syafii who forbids the practice of buying and selling unseen. Keywords: VTube, Money Game, Fikih Muamalah
