Abstract

Sadu District is located in East Tanjung Jabung Regency and consists of 9 villages, one of which is Sungai Jambat Village which is characterized by turbid, wavy, muddy, and sandy waters. The majority of fishermen in Sungai Jambat Village use bottom gillnet fishing gear with a mesh size of 3.5 inches and 4 inches. The purpose of this study was to compare the catches of bottom gillnet with mesh sizes of 3.5 inches and 4 inches in the waters of Sungai Jambat Village. The method used in this research is the experimental fishing method. The data collected includes environmental parameters, catch per species (head), and number of catches (head), weight per species (kg), and the total weight of catch (kg). The data analysis used is the descriptive analysis of an independent sample t-test. The results showed that the 3.5-inch mesh treatment was significantly higher than the 4-inch mesh treatment (p<0.05) in terms of the number and weight of bottom gillnet catches. In the 3.5-inch mesh size, the catch was 3,067 individuals with a weight of 248.40 kg, and the number of catches in the 4-inch mesh size was 2,820 individuals with a weight of 234.60 kg. The highest number of catches was leaftail croaker found in a 3.5-inch mesh size of 1,393 individuals, and mantis shrimp was the heaviest catch in a 3.5-inch mesh size weighing 69 kg. Pomfret is the lowest catch in terms of quantity and weight. The conclusion of this study in terms of the number and weight of catches with a 3.5-inch mesh size is higher than the 4-inch mesh size.

Abstract

Community structure is a concept that studies the composition of species and abundance in a community. This research was conducted in April 2022 in the waters of Tidung Island, Seribu Islands Regency. The purpose by conducting this study was to determine the structure of the bivalve community which includes species, density, relative density, diversity, uniformity, dominance, distribution pattern and index of similarity. The research method used in this study is survey method, were carried out at 3 stations, station determination using purposive sampling method taking into account the anthropogenic conditions in the study area. Based on results, types of bivalves found consisted of 6 species of bivalve. The species most commonly found is Atrina pectinata. The abundance of bivalve obtained ranged from 2.67 – 5.47 ind/m2. The results of the ANOVA test between observation stations obtained the value of sig. <0.05, so it can be concluded that the density of Bivalvia between stations was significantly different, except for stations I and III. The distribution pattern of bivalves in the waters of Tidung Island is in groups. The value of the Diversity Index in the study area is classified as moderate (2.06 – 2.12). The uniformity index value during ranged from 0.80 – 0.82 wich is included in the balanced category. The dominance index between stations is different with a value range of 0.25 – 0.28 which means that no species dominates at each station.

Abstract

This research was conducted in March 2022 at the estuary of the Kambang River, Pesisir Selatan Regency, West Sumatra. This study aims to analyze the structure of the zooplankton community based on depth. The method used is a survey method by determining the sampling location by purposive sampling and zooplankton sampling points by stratified sampling. Sampling of zooplankton utilizing a water pump and filtered using plankton net no. 25, then brought to the laboratory to be identified and the community structure calculated. Sampling was accompanied by water quality pH, temperature, salinity, brightness, current velocity and DO measurements. Four zooplankton species were found in the Kambang River Estuary: Aetideus armatus, Macrosetella sp., Oithona sp., and Cyclops sp. The average value of zooplankton abundance during the day ranged from 1,938.61 - 2,492.50 ind/L, and in the afternoon 1,938.61 - 2,769.45 ind/L, the diversity index during the day was 1.28 - 1.55 and in the afternoon 1.28 - 1.36, the index of uniformity during the day was 0.72 - 0.98 and in the afternoon 0.86 - 0.98, while the index of dominance during the day was 0.40 - 0.53 and in the afternoon 0.40 - 0.52. The one-way ANOVA test results obtained an average value of 0.010 during the day and 0.029 in the afternoon, meaning there was a significant difference in zooplankton abundance between research depths

Abstract

This research aims to understand the supply chain of marine catches from fishermen to consumers in the Wonorejo village area. Data was collected through in-depth interviews with three fishermen and two collectors in the area. The findings indicate that the limited number of collectors can significantly impact the distribution of marine catch and, subsequently, the fishermen's income. Moreover, variations in the type of fish caught play a pivotal role in influencing the distribution dynamics within the market. While there's an apparent need for interventions to enhance the supply chain's efficiency and promote a more equitable distribution of income, it's vital to note that this study's limitations, including sample size and geographic scope, necessitate its results to be viewed as preliminary. Future research in a broader setting must confirm and expand upon these findings.

Abstract

The quality of the catch can be seen from the fish storage container used to maintain its temperature. An insulated storage area can maintain ice resistance during the operation of fishing gear, as well as during the transportation of the catch to the fish landing site. Generally, fishermen use fish storage containers made of fiber with insulation in the form of polyurethane. Some fish storage containers are made from polystyrene-insulated styrofoam. This research aims to determine how optimal cooling is using coconut fiber and sugar cane bagasse insulation. The method used in this research was an experimental method using a Completely Randomized Design (CRD) with one control (Styrofoam cooler box), two treatments (Coconut fiber insulated cooler box and sugarcane bagasse), and three repetitions. The dimensions of the coolbox are the same as those on the market, namely 42 cm x 26 cm x 23 cm and a thickness of 2 cm. The lowest temperature of the coolbox made from coconut fiber insulation, 17.7 °C, was reached after the 70th minute. The bagasse was only able to reach the lowest temperature of 19.4°C, achieved in the 60th minute. Temperature stability in the coconut fiber coolbox reached 2 hours 10 minutes (130 minutes) from 80-200 minutes, while the bagasse coolbox reached 3 hours 40 minutes (220 minutes) from 70-280 minutes.

Abstract

The purpose of the study was to analyze hydrolysate astaxanthin as an inhibitor of the enzyme alf glucosidase. The method used is an experimental method by applying a Complete Random Design (RAL) The treatment used is a concentration of different papain enzymes, consisting of 3 treatment levels namely t1 (3%), t2 (6%), and t3 (9%). Observations made are 1) proximal analysis; 2) analysis of hydrolysate astaxanthin and its antioxidant activity; 3) analysis of the inhibition test of the enzyme alpha glucosidase and its inhibitory mechanism. The results showed that the proxmat of vanname shrimp skin flour is; water content (9.20% bb), ash (31.46% bk), fat (1.64% bk), protein (37.60% bk), and carbohydrates (29.29% bk) (by different) with a yield of 36.22%. The highest astaxanthin content at the 3% papain enzyme concentration of 3.57 μg/g with the best antioxidant activity has the smallest IC50 value of 88,793 ppm and astaxanthin shows inhibition activity of alpha glucoside enzyme by 49.38% - 58.87% and astaxanthin has a competitive enzyme inhibition mechanism resulting in a decrease in postrandial blood glucose levels.
