It is important to identify problems related to trap placement so thatthe productivity of fish resources can be optimal. This research aims to analyze thecomposition of fish species caught, length at first capture, and differences in catchrate of bottom traps based on different fishing locations. The research was carriedout from April to October 2023 in Talaga Nipa Hamlet, Waisala District, and WestSeram Regency using experimental fishing methods. The results of the research showed that there were 20 species of fish caught in the waters of Sanahuni Hamlet (Location A), with the most dominant type of fish being Pterocaesio tile, namely31.40%. Meanwhile, in the waters of Haya Pulo Hamlet (Location B), 16 species offish were caught, with the most dominant species being Scarus rubroviolaceus at22.86%. On average, caught fish such as Caesio cunning, Scarus rubroviolaceus andCaesio caerulaurea are caught before they reach maturity. The bottom trap catchrate in the waters of Sanahuni Hamlet (Location A) is higher than in the waters ofHaya Pulo Hamlet (Location B). Differences in the number and types of fish caughtin traps can be influenced by various factors, such as fish migration, foodabundance, oceanographic conditions, trap design and construction, depth ofoperation of fishing gear, and damage to coral reefs due to destructive bomb fishing

Pengaruh Pemberian Vitamin E Dengan Dosis Yang Berbeda Pada Pakan Terhadap Pemijahan Lobster Air Tawar (Cherax quadricarinatus)
Get PDFFreshwater lobster (Cherax quadricarinatus) is a type of lobster that has the potential for developed as a cultured organism. The problem that often occurs is the low number of freshwater lobster production due to the relatively long reproductive time. Vitamin E is a nutrient that plays a role in improving the spawning process in animals. This research aims to determine the effect of vitamin E to artificial feed at different doses on spawning. The test animals used were 16 female freshwater lobsters measuring 4 inches, aged 6 months, with an average weight of 30-55 grams. The research was conducted over 60 days using an experimental method with a completely randomized design (CRD) consisting of 4 treatments with 4 replications each. Treatment A was without vitamin E, Treatment B had 250 mg/kg of feed, Treatment C had 450 mg/kg of feed, and Treatment D had 650 mg/kg of feed The results showed that the levels of gonad maturity, fecundity, degree of fertilization, egg hatchability, and survival rate were not significantly different among treatments. However, Treatment C yielded the best results, with a gonad maturity level of 10.60%, fecundity of 281.53 eggs, a fertilization rate of 8.59%, a hatchability rate of 62.50%, and a survival rate of 100%. Data analysis was conducted using analysis of variance (ANOVA) at a 95% confidence level. The results indicate that the addition of vitamin E to feed at different doses does not significantly affect the spawning of freshwater lobsters

Resiliensi Mahasiswa dari Keluarga Petani Sengon dalam Menghadapi Gagal Panen Akibat Karhutla
Get PDFThis research examines the resilience of students from sengon farming families in Pulang Pisau Regency in facing crop failure due to forest and land fires (karhutla). Descriptive qualitative methods were used through interviews, observations and literature studies. The research results show that forest and land fires, which are often caused by burning land without permission, cause significant economic losses for sengon farmers and their families. Affected students adopted resilience strategies such as income diversification, utilization of scholarships, good financial management, and sustainable agricultural development. Social support from the government and local communities focuses on preventing forest and land fires, but direct economic support is still minimal. This research highlights the importance of strengthening capacity and education for sengon farming families and students to build resilience in facing forest and land fires. The resilience demonstrated by students and families of sengon farmers in Pulang Pisau District-through diversification of income sources, utilization of social networks, and small-scale agricultural innovations-indicates that strengthening social capital and adaptive capacity are key to maintaining welfare sustainability amid the ecological and economic crisis caused by forest and land fires

PENGARUH BUDAYA SUKU ARFAK (HATAM-MEYAH-MOILE-SOUGB) TERHADAP PERENCANAAN DAN PEMBANGUNAN INFRASTRUKTUR KOTA DI KABUPATEN MANOKWARI
Get PDFThe Papuan community strongly identifies with its culture and customs. What happens in Papua in general, and specifically in Manokwari Regency as the oldest city in Papua/the city where the Gospel entered the Land of Papua, a city rich in history and culture, has not fully actualized its culture into the governance framework established in the regulations of the regency government, the Regional People\u27s Representative Council (DPRD), the Papuan People\u27s Assembly (MRP), the Customary Council (DAP), NGOs, and the Customary Institutions (LMA). Law Number 21 of 2001 granted the Provinces of Papua and West Papua a special status. To this day, the uniqueness and distinctiveness of other regions in Indonesia do not guarantee that planning and development will follow and respect the culture and customs of the indigenous Papuan people, as stipulated in the Special Autonomy Law. Private sectors, state-owned enterprises, the government, and NGOs are rapidly developing their plans, but they do not incorporate the local wisdom of the community. The Papuan people are beginning to erode and neglect their culture, which serves as their symbol and identity. Therefore, the implementation of planning and development rules based on local wisdom, along with the modeling of forms, attributes, carvings, decorations, and ornaments, is a tangible manifestation of cultural preservation.Recognizing that the city of Manokwari\u27s infrastructure development cannot ignore the long-standing values and cultural aspects is crucial. This embodies the aspiration and desire of the Manokwari people to be active participants in their land and culture, not merely spectators.The Papuan community strongly identifies with its culture and customs.
