The potential of fisheries resources in Indonesia is 9,931 million tons per year, with the highest potential being in WPP 718 of 1,992 million tons / year (20%), in WPP of 1,228 million / year (12%) and in WPP 711 of 1,143 million tons / year (12%). Bigeye Tuna (Thunnus obesus) is one of the leading commodities from the fisheries sub-sector which is commonly consumed both locally and export. Cilacap Ocean Fishery Port (PPS), Cilacap Regency, is one of the Bigeye Tuna (Thunnus obesus) fish landings caught from the Indian Ocean. This study aims to find out information on the long-term weight ties of Bigeye Tuna (Thunnus obesus) captured from the Indian Ocean and landed at PPS Cilacap, Central Java. According to Cilacap PPS (2014), Bigeye Tuna (Thunnus obesus) fish is one of the large pelagic fish species with the most catches after skipjack fish from all landed fish. The results of the analysis of the relationship between weight weights show that the growth pattern of big eye tuna (Thunnus obesus) is allometric negative (b <3). In fisheries biology, this long-weight relationship of fish is one of the information that needs to be known in terms of fisheries resource management.

Pineapple plants are one of the leading fruits that have high economic potential in Indonesia, but often pineapple cultivation is not optimal, especially in terms of land management. The implementation of this PKM aims to provide socialization on correct soil processing to pineapple farmers in Harum Manis, Kubu Raya Regency. Pineapple farmers in that location still don't understand how to cultivate the land properly and just plant like that. Moreover, there are many obstacles currently faced by farmers, such as land shortages and extreme climate change. The method used in implementing this PKM is direct socialization followed by questions and answers. The activity went very well as shown by the enthusiasm of the farmers participating in this activity. It is hoped that after this PKM activity is completed, pineapple farmers can carry out proper soil processing to increase optimal pineapple growth and production.

Jatigede Reservoir receives water masses and materials from the Cimanuk River, such as nutrients, sediments, and waste, including microplastics. This study aims to analyze the presence of microplastics in the digestive tract of caught fish in Jatigede Reservoir. Fish samples were obtained from fishermen, fish collectors, and fish farmers. Microplastic observations were carried out in the stomach and intestines of fish through the stages of observing fish eating habits, extraction, followed by FTIR analysis to determine the presence, abundance, and type of polymer. Carnivorous fish have the highest amount of microplastics. There is a marked difference between the amount of microplastics and the origin of fish intake. The shorter the fish's gut, the greater the amount of microplastics found. Based on their shape, the type of microplastic is dominated by fibers with a blue color. The most common polymer found is nylon. The digestive tract of fish in Jatigede Reservoir already contains microplastics of various types and colors, with varying amounts, according to the nature of eating fish.

Keberadaan situ memiliki peran ekologis dan hidrologis yang penting, di antaranya sebagai penyimpan air hujan, pengendali banjir lokal, sumber air untuk irigasi, habitat biota air tawar, serta penunjang keanekaragaman hayati. Batimetri merupakan ilmu yang mempelajari topografi dasar perairan, baik perairan laut maupun perairan darat seperti danau, waduk, dan sungai. Dalam konteks perairan darat di Indonesia terkhusus di perairan situ di Kabupaten Bogor belum banyak yang memuat informasi peta batimetri situ. Studi batimetri ini memiliki peran penting untuk memahami bentuk dasar perairan, volume air, serta distribusi kedalaman yang memengaruhi sirkulasi air, sebaran organisme, dan proses ekologis lainnya. Teknik interpolasi menggunakan metode Kriging pada ArcGIS 10.8, diperoleh gambaran kontur kedalaman yang jelas, dengan distribusi titik pengukuran yang berbeda pada tiap situ, yaitu 377 titik di Situ Cilala, 1032 titik di Situ Gede, dan 107 titik di Situ Salabenda. Situ Cilala memiliki luas perairan terbesar (108.697,56 m²) dengan kedalaman maksimum ±5 meter, terutama pada bagian utara dan tengah situ. Situ Gede, dengan luas 59.222,20 m², memiliki kedalaman maksimum ±2 meter yang terkonsentrasi di bagian tengah. Kedangkalan pada bagian selatan (kurang dari 1 meter). Sementara itu, Situ Salabenda memiliki luas terkecil (32.291,00 m²) dengan kedalaman maksimum ±4 meter di tengah danau. Secara umum, pola kedalaman ketiga situ memperlihatkan bahwa zona terdalam cenderung berada di tengah atau utara perairan, sedangkan zona dangkal berada di bagian selatan.

Lemukutan Island is a marine conservation area in Bengkayang Regency, West Kalimantan, with high marine resource potential. Besides supporting tourism activities such as diving and snorkeling, its waters host ecologically important giant clams (Tridacnidae), which function as natural biofilters in reef ecosystems. However, information regarding the biodiversity and population status of giant clams in this area remains limited. This study aimed to assess the density and distribution patterns of giant clams in the waters of Lemukutan Island. Field data were collected in July 2025 at four observation stations representing the eastern and western parts of the island using the belt transect method (50m x 5 m). Data analysis included calculations of density, relative abundance, and distribution patterns using the Morisita Index. A total of 329 individuals belonging to three species were recorded: Tridacna crocea, T. maxima, and T. squamosa. T. crocea was the most dominant species at all stations, with the highest average density (0.231 ind/m²) and relative abundance (14.732%). In contrast, T. squamosa showed the lowest average density (0.067 ind/m²). Station 2 exhibited the highest overall density (0.254 ind/m²) and relative abundance (16.241%) compared to other stations. The distribution pattern of giant clams was predominantly clumped. However, a more uniform distribution of T. crocea and T. maxima was observed at Stations 3 and 4. Variations in density and distribution were closely associated with coral reef availability and water quality conditions. These findings provide baseline data to support sustainable conservation and management of giant clams in Lemukutan Island waters.

Lemukutan and Penata Besar Islands located in Bengkayang Regency, are characterized by coral reef formations and relatively clear waters that meet the ecological requirements for the natural habitat of the lola snail, Trochus niloticus. This study aimed to analyze the size–frequency distribution and spatial distribution pattern of T. niloticus in the waters of Lemukutan and Penata Besar Islands. Sampling was conducted using the belt transect method (50 m × 4 m) at four stations: Tanjung Jati, Penata Besar, Tanjung Batu Bedaon, and Melanau Timur (Batu Kapal). A total of 67 individuals were recorded during the study, consisting of 12 individuals (17.91%) at Tanjung Jati, 15 individuals (22.39%) at Penata Besar, 27 individuals (40.30%) at Tanjung Batu Bedaon, and 13 individuals (19.40%) at Melanau Timur (Batu Kapal). The population was dominated by individuals in the size classes of 8.5–9.1 cm and 9.1–9.7 cm, representing 34% of the total observations, indicating a predominance of medium-sized individuals. Spatial distribution analysis using the Morisita Index revealed a clumped distribution pattern (Id > 1) at Penata Besar, Tanjung Batu Bedaon, and Melanau Timur (Batu Kapal). In contrast, the population at Tanjung Jati exhibited a random distribution pattern (Id = 0.86). These findings provide baseline ecological information to support sustainable management and conservation strategies for T. niloticus in the study area.
