Abstract

The rapid development of fish farming using the Floating Net Cage (KJA) system has raised concerns about the water quality of the reservoir. This study aims to evaluate the water quality in KJA and non-KJA areas of the Jatigede Reservoir based on the physical-chemical parameters of the water. Analysis was conducted at four stations with varying levels of KJA activity. The results showed that, based on Government Regulation No. 22 of 2021, the pH and BOD parameters have exceeded the established quality standards. However, Jatigede Reservoir is still considered suitable for fisheries activities as other water quality parameters remain within the standards for Class II and III water. This study is expected to serve as a basis for the sustainable management of Jatigede Reservoir, aiming to mitigate the negative impacts of KJA on water quality while supporting its utilization as an economic livelihood resource for the local community.

Abstract

Global warming is a phenomenon of increasing the average temperature of the earth's surface. Carbon can be stored in various forms in ecosystems, one of which is the concept of blue carbon. This research aims to analyze the condition of the mangrove ecosystem and the potential for carbon storage in the mangrove forest rehabilitation area in Sebele Village, Karimun Regency, Riau Islands. This research was conducted from October 2024 to July 2025 in the mangrove forest rehabilitation area of Sebele Village, Riau Islands Province. The method used in this research is the survey method. Standing biomass data was obtained using allometric equations. The research results show that the level of tree density in the mangrove forest rehabilitation area of Sebele Village is in the Sparse category. At the tree level, it is dominated by the Xylocarpus granatum species, while at the sapling level it is dominated by the Rhizophora mucronataspecies. The highest carbon storage value is found in the Avicennia marina species with a carbon storage value of 14.44 tons/ha. And the potential carbon storage from the calculation results obtained a carbon storage value of 61.43 tons/ha. The carbon storage value is directly proportional to the standing biomass. The greater the standing biomass, the greater the carbon stored.

Abstract

Innovations to increase protein content in tortilla chips can be achieved by adding skipjack tuna flour. This study aims to analyze the percentage of skipjack tuna flour addition in the production of tortilla chips that are most preferred by panelists and to analyze the proximate composition of the most preferred tortilla chips. This study was conducted at the Fisheries Product Processing Laboratory, Faculty of Fisheries and Marine Sciences, University of Padjadjaran, and the Laboratory of PT Saraswanti Indo Genetech in February 2025. The research method used was experimental with 4 treatments and 25 semi-trained panelists as replicates. The treatments involved adding skipjack tuna flour to tortilla chips at levels of 0%, 7.5%, 10%, and 12.5%. The parameters observed were organoleptic characteristics (appearance, aroma, texture, taste) and chemical characteristics (protein content, ash content, fat content, moisture content, and carbohydrate content). The data obtained will be analyzed using the Friedman test and Bayes' equation. The study concluded that the addition of 12.5% skipjack tuna flour was the most preferred treatment, with an average score of 6.28 for appearance, 7.64 for aroma, 8.04 for texture, and 8.84 for taste. The alternative value for the treatment with 12.5% skipjack tuna flour addition was 8.21. The proximate analysis results of the most preferred tortilla chip treatment showed a protein content of 7.56%, ash content of 1.82%, fat content of 20.67%, moisture content of 4.35%, and carbohydrate content of 65.60%.

Abstract

Mangrove ecosystems play an important role in maintaining coastal biological balance, protecting land from erosion, providing habitats for various biota, and functioning as effective carbon sinks. Indonesia has the largest mangrove area in the world, covering approximately 3.3 million hectares, but this ecosystem continues to experience degradation due to land conversion, with a rate of destruction reaching 530,000 hectares per year. This degradation reduces the ecological and economic functions of mangroves, necessitating vegetation structure analysis to assess the condition of the ecosystem. This study aims to analyze the vegetation structure of mangroves in Pengarengan Village, Pangenan District, Cirebon Regency, which is one of the oldest mangrove areas in Cirebon. Data collection was carried out at three stations using the Transect Line Plot method with plot sizes of 10×10 m² for trees, 5×5 m² for stakes, and 1×1 m² for seedlings. The parameters observed included density, frequency, and dominance, which were then used to calculate the Importance Value Index (IVI). The results showed that the mangrove vegetation at the study site was dominated by the species Rhizophora mucronata and Avicennia marina. The density of tree-level vegetation was classified as moderate to dense, with the highest density found at Station II (2,433 ind/ha) and the lowest density found at Station I (1,200 ind/ha). The INP value reached 300% for each species at all stations at the tree and stump levels, indicating the dominance of one species at each station
