Abstract

Access to capital is very important in the development of small fishery businesses. This study aims to analyze the access to the capital of small fishermen in Bandar Lampung City Gudang Lelang. The research method uses a qualitative approach with a case study method. Data was obtained by in-depth interviews, participant observation, and document analysis; Furthermore, it was analyzed to explain the access to capital of small fishermen. The results of the study show that most small fishermen have difficulties accessing capital through banks. Most of them access non-formal capital, such as mobile lending, a door-to-door system known as bank keliling, loan sharks, Madani Mekaar National Capital, Syariah National Retirement Savings Bank, and Amartha. In addition, fishermen were used to borrowing money from skippers, subscription stalls, or their families to meet their needs at sea. They need the government’s support and mentoring in accessing bank capital to develop their businesses. Capital difficulties for fishermen’s businesses should be evaluated by banks to provide a more flexible system that is easily accessible.

Abstract

The decline in mangrove land cover is a serious concern, because it can increase the possibility of sea water intrusion in coastal areas. This research aims to assess the relationship between surface water quality and mangrove density on Pasaran Island. The data obtained were analyzed using the multiple linear regression method to evaluate the simultaneous influence of mangrove density and sampling zone on various water quality parameters, including salinity, dissolved oxygen, electrical conductivity, total dissolved solids, and pH. The research results show that the denser the mangrove density, the lower the salinity level, but the density does not affect other water quality parameters, such as: dissolved oxygen, electrical conductivity, total dissolved solids, pH. The sampling zone also influences several water quality parameters, where zones closer to the coastline show higher parameter values ​​than transition zones or those further from the coast. External factors such as sea water intrusion and domestic waste pollution play a greater role in influencing water quality. The government should make efforts to conserve and rehabilitate forests and mangrove lands, especially in urban areas.

Abstract

Gelasa Island has a coral reef ecosystem as a habitat for biota including coral reef fish, turtles, and others. The coral reef has been damaged due to anthropogenic activities. The purpose of the study was to determine the percentage of coral reef cover and the abundance of coral reef fish. The study was conducted in March 2024 in the waters of Gelasa Island. The method used was UPT (Underwater Photo Transect) for coral reefs and UVC (Underwater Visual Census) for coral reef fish, and the PAST 4.03 application to determine the diversity, uniformity, and dominance index. The results of the study showed that the percentage of coral reef cover in the waters of Gelasa Island was in the good category with an average of 52.42%. The abundance of coral reef fish was 49,114 ind/ha in the very rare category. The highest abundance of coral reef fish species was Neopomacentrus anabatoides, Pomacentrus alexanderae, and Caesio cunning. Based on the category, major fish have the highest abundance. The diversity value is in the moderate category, the uniformity value indicates an unstable community, and the dominance value is in the low category.

Abstract

Industri perikanan budidaya laut menghadapi tantangan besar dalam pengendalian penyakit yang disebabkan oleh bakteri patogen. Salah satu patogen yang sering menyerang ikan budidaya adalah Vibrio parahaemolyticus, yang dapat menyebabkan vibriosis pada ikan laut. Penelitian ini bertujuan untuk mengetahui karakter bakteri patogen Vibrio parahaemolyticus yang ditemukan pada ikan Bawal Bintang (Trachinotus blochii) di perairan Teluk Hurun, Lampung, serta menguji potensi antibakterinya. Karakterisasi bakteri V. parahaemolyticus meliputi uji media selektif CHROMagar Vibrio (CV), konfirmasi gen toxR dengan metode PCR, aktivitas hemolitik pada medium blood agar plate (BAP)  uji biokimia dengan metode API 20E, uji patogenisitas secara in vio pada bawal bintang, dan uji sensitivitas terhadap antibiotik dan bahan antimikrobia. Hasil penelitian menunjukkan bakteri V. parahaemolyticus tumbuh pada media CAV dengan warna biru kemerahan, teramplifikasi gen toxR, hemolitik positif, morfologi koloni berwarna krem dengan tepi bergelombang, mampu memfermentasi beberapa karbohidrat, termasuk glukosa, mannitol, dan sukrosa. Uji patogenisitas in vivo pada ikan bawal bintang menunjukkan gejala klinis berupa lesu, peradangan pada sirip, dan perdarahan, yang menandakan bahwa Vibrio parahaemolyticus merupakan patogen penyebab vibriosis pada ikan. Uji antibakteri menunjukkan bahwa enrofloxacin adalah antibiotik yang paling efektif, diikuti oleh tetrasiklin dan oksitetrasiklin. Ekstrak jintan hitam menunjukkan hasil yang lebih bervariasi, meskipun tetap menunjukkan potensi antibakteri alami. Penelitian ini diharapkan dapat memberikan dasar yang lebih kuat untuk pengendalian vibriosis di perikanan budidaya serta mendorong pengembangan alternatif antibakteri alami.
