Abstract

The Bengkulu City area with a large capture fishery activity is in the Sungai Serut District, precisely in the Pasar Bengkulu Village. Bubu Lipat is a fishing gear that is categorized into traps that are operated passively using bait. This research aims to analyze the technical and productivity of fishing gear used by fishermen in Pasar Bengkulu. It is expected to provide information, descriptions, and explanations about the development of traps to the government and related stakeholders for trap management in Pasar Bengkulu. The scope of the research data includes primary and secondary data, fishing gear construction, and catch productivity. Data collection was carried out through field observations, interviews, and documentation. The researchers conclude that the productivity of a trap per year is 1500 kilograms, and the productivity per trip is 30 kilograms. The catch of trap consists of two types, Keong Macan (Babylonia spirata) and Rajungan (Portunus pelagicus), and fishing vessels used by trap fishermen at the Pasar Bengkulu have two sizes, 1 and 2 GT with respective endurance of 10.5 PK and 26 PK. It is necessary to research the effectiveness of catching traps in Pasar Bengkulu to obtain more information regarding managing fishing gear in Pasar Bengkulu.

Abstract

Bakteri merupakan suatu organisme yang memiliki satu sel (uniseluler), prokariota (prokariotik), dan berukuran mikroskopik (berukuran sangat kecil) sehingga memerlukan alat bantu berupa mikroskop untuk bisa melihatnya. Bakteri terdiri atas ± 68.000 spesies, sehingga dalam identifikasi spesies bakteri juga perlu dilakukan pengamatan secara morofologi terhadap bakteri dengan berdasarkan bentuk, warna, dan jumlah koloni. Tujuan dari dilakukannya penelitian ini yaitu indentifikasi bakteri melalui pengamatan morfologi secara makroskopik dan uji biokimianya dimana hasilnya didapatkan bakteri dari genus Vibrio yang terdiri atas 3 spesies yaitu Vibrio harveyi, Vibrio palahaemolyticus, dan Vibrio alginolyticus. Kesimpulan yang dapat diambil dari penelitian ini yaitu, bakteri yang berhasil ditemukan di dalam tubuh lobster pasir (Panulirus homarus) terdiri atas 3 spesies Vibrio, yaitu Vibrio harveyi, Vibrio palahaemolyticus, dan Vibrio algynolyticus yang diidentifikasi dengan menggunakan dua metode yaitu pengamtan berdasarkan morfologinya dan melalui uji biokimia.

Abstract

AbstractRed snapper is a type of reef fish that has high value, so it is necessary to research on the growth pattern of red snapper to determine the growth pattern landed at PPI Lhok Bengkuang. This study aims to determine the growth pattern of red snapper landed by fishermen at PPI Lhok Bengkuang. In order to know the growth pattern of L. timoriensis through the long-weight relationship of the fish from the growth aspect of the fish's weight and length. The research was conducted in October–November 2022 at PPI Lhok Bengkuang, South Aceh District. The research method was proportional random sampling and then the data were analyzed using linear regression. The number of individual samples whose growth patterns were analyzed was 30 individuals with the type of species L. timoriensis. Total body length ranges from 22.4 cm-30.3 cm and body weight ranges from 161 grams-455 grams. The results of the regression analysis on L. timoriensis individuals obtained a regression value (b) of 0.0989391 with a coefficient of determination (R2) of 0.7180290 which indicates that the weight gain is 72%. The value of b = 0.0989391 means that it is smaller than the normal b value, it is called a negative allometric growth pattern, that is, the length relationship is faster than the weight of the fish. On the growth pattern of L. timoriensis, it is necessary to carry out further research with a longer time and a larger number of samples to obtain more complete data and information.

Abstract

Monitoring the quality and condition of waters is an importantactivity to carry out, especially in coastal waters which are veryeasily contaminated and prone to pollution. The waters of PasirMayang Beach are influenced by inputs from rivers and theactivities of coastal communities, which in turn affect the waterquality and aquatic organisms. The purpose of this study was todetermine the condition of water quality using seawater qualitystandards and map them spatially. Water quality parameterssurveyed included temperature, salinity, pH, oxygen level andbrightness which were measured at 17 survey locations. Thesurvey method used was direct data measurement and the datawas grouped into tabular form using Ms. Excel 2010 and theresults were compared and matched with seawater qualitystandards stipulated by the Minister of Environment RegulationNo. 51 of 2004. Spatial distribution was carried out using ArcGIS10.4 software and interpolated using the inverse distanceweighting (IDW) method. Measurement and analysis results wereobtained for temperature parameters between 30-31.6 °C.Salinity 11.3 to 21.7 ‰. pH 7.0-7.9;DO 2.1-3.6mg/L. Based onthe research results, the following conclusions can be drawn:Some of the seawater quality of Pasir Mayang Beach still meetsthe established quality standards, including temperature and pH,so that it can be further classified according to its function.However, there are several parameters that do not meet qualitystandards, namely: Salinity, DO and Clarity. For theeDOparameter, thereeareeseverallresearchhstationssthat are stillwithin or below the quality standard.

Abstract

The destruction of mangrove forests reduces forest area and mangrove plant species. Mangrove forest restoration requires seeds that have good growth and are resistant to pests and diseases. The purpose of this study was to determine the effect of the growth of mangrove seedlings on the application of fertilizer to the hydraquent garden media at the Aceh Jaya Mangrove Institute Foundation. The research was conducted in September 2022. This research was carried out experimentally which was arranged based on 5 treatments and 4 replications, which was 20 times. Each unit consists of 3 seeds, 2 of which are test plants, so the number of seeds needed is 60 seeds. The results of this study indicate that the Hydraquent Media Foundation of the Aceh Jaya Mangrove Institute has an effect on the parameters of plant height, number of leaves, root volume, root canopy ratio and seedling dry weight. There is an interaction between dose treatments on various hydraquent tampon media at the Aceh Jaya Mangrove Institute Foundation
