PROCESSING AND FOOD SAFETY OF WHOLE CLEAN CUTTLEFISH (Sepia sp.) FROZEN WITH THE IMPLEMENTATION OF GMP AND SSOP

Pola S. T. Panjaitan — 2025-10-13

Indonesia has significant aquatic resource potential, especially in its marine waters. One of its leading fishery products is cuttlefish, which is abundant in Indonesian waters. This study aims to examine the characteristics of frozen Whole Clean Cuttlefish processed in accordance with Good Manufacturing Practices (GMP) and the Standard Sanitation Operating Procedure (SSOP). The implementation of GMP and SSOP is essential to ensure the quality and safety of fishery products, as fish-based products are highly perishable. Therefore, improving food safety standards is necessary to maintain the quality of frozen Whole Clean Cuttlefish for consumers.

THE EFFECT OF FERMENTED DUCK BONE FLOUR DOSAGE USING MIXED MICROORGANISMS ON INCREASING FEED NUTRITION AND GROWTH OF NILE FISH (Oreochromis niloticus)

Zennur Rahman Hadi — 2025-10-13

The high cost of fish feed in Indonesia, particularly in Sidenreng Rappang Regency, remains one of the main challenges in aquaculture development. This study aimed to determine the effect of different doses of mixed microorganisms in fermented duck bone meal on feed consumption, growth performance of Nile tilapia (Oreochromis niloticus), and hepatosomatic index (HSI). The research used a Completely Randomized Design (CRD) consisting of five treatments and three replications, resulting in 15 experimental units. The culture system used floating net cages measuring 2 meters in length, 1 meter in width, and 0.5 meters in height, each divided into five compartments measuring 40 × 40 cm. The treatments were as follows: A = 10% fermented duck bone meal, B = 15%, C = 20%, D = 25%, and E = 30%. Sampling was carried out weekly to monitor the weight of the fish and adjust feed allocation. Data were analyzed using analysis of variance (ANOVA), and if significant differences were found, the W-Tukey post hoc test was applied to identify the best-performing treatment. Water quality parameters, including temperature and pH, were measured daily using a digital thermometer and a pH meter. The results showed that Treatment D yielded the best proximate composition of feed with a crude protein content of 38.72%. In terms of growth and feed consumption, Treatment D also recorded the highest values, with a growth rate of 4.796±0.10 g and feed consumption of 11.73±0.13 g. However, the highest hepatosomatic index (HSI) was observed in Treatment A, with a value of 3.11±0.32.

SUSTAINABILITY ANALYSIS OF MUNDU MANGROVE ECOTOURISM, MUNDU PESISIR VILLAGE, MUNDU DISTRICT, CIREBON REGENCY

Mundu Mangrove Ecotourism is located in Mundu Pesisir Village, Mundu District, Cirebon Regency. Ecotourism is a form of tourism that is managed through a conservation approach. This study aims to analyze the sustainability status of mangrove ecotourism based on five dimensions of ecology, economy, socio-culture, infrastructure, and institutional law using the RAPFISH approach, identify critical attributes that affect sustainability, and formulate mangrove ecotourism development strategies in Mundu Pesisir Village. Data were collected through field surveys, interviews, and questionnaires to various stakeholders, then analyzed using the Multidimensional Scaling (MDS) method through RAPFISH (Rapid Appraisal Technique for Evaluating Fisheries Sustainability). The results of the sustainability analysis based on 5 dimensions, namely the ecological dimension of 48.33 (less sustainable), the economic dimension of 22.05 (unsustainable), the socio-cultural dimension of 53.13 (moderately sustainable), the infrastructure dimension of 32.14 (less sustainable), and the institutional legal dimension of 76.03 (sustainable). The results of the analysis show that there are still many things that need attention to improve the sustainability score, especially in dimensions that still get a small score.

ANALYSIS OF VEGETATION STRUCTURE IN THE MANGROVE ECOSYSTEM OF PENGARENGAN, PANGENAN, CIREBON REGENCY

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
