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

The research was conducted in June - August 2022 in the coastal waters of Padang and Pariaman, West Sumatera. The method used in this research was a survey method. This research aims to determine the organic matter content of the sediment, the abundance of macrozoobenthos, and the relationship between sediment organic matter and the quantity of macrozoobenthos. Sampling was designed by purposive sampling by using 20x30 cm2 Ekman grab. The organic matter content of sediments in the Padang and Pariaman Coastal Waters, West Sumatra, ranged from 4.09 to 7.53%. The average abundance of macrozoobenthos at the four stations ranged from 20.37 to 90.74 ind/m2. Based on the identification results, the macrozoobenthos class found in the coastal waters of Padang and Pariaman consists of Bivalvia, Gastropods, and Malacostraca. The analysis of the sediment organic matter showed weak position relationships with macrozoobenthos abundance.

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.

Abstract

One of the tourism areas in Dumai City is Medang Kampai District, which is a coastal area with an area of ​​373.00 km2. Coastal areas are always used for human activities, one of which is coastal ecotourism which is a coastal tourism activity developed with a conservation approach and utilizing the characteristics of coastal resources as tourist destinations. Medang Kampai District has many coastal ecotourism areas, including Pulai Humpback Beach, Pesona Alam Mundam Beach, Aulia Dumai Beach, Marina Puak Beach, Koneng Beach, Acacia Indah Guntung Beach and Legenda Beach. The method used in this study is a survey method, which was set at 5 (five) research locations, namely Pesona Alam Mundam Beach (Station I), Aulia Dumai Beach (Station II), Koneng Beach (Station III), Acacia Indah Guntung Beach (Station IV), and Legenda Beach (Station V). Based on the results of data processing using DSAS software, the results showed that the coast in the Medang Kampai sub-district was dominated by abrasion with an average abrasion rate of -2.96 m/year. The highest abrasion occurred at Acacia Indah Guntung Beach, followed by Pesona Alam Mundam Beach, Legenda Beach, Aulia Dumai Beach, and Koneng Beach. The impact on the coastal ecotourism area due to abrasion is that several facilities and infrastructure have been damaged and there has been a reduction in the area of ​​coastal ecotourism which is thought to cause a reduction in the capacity of visitors while at the same time directly impacting the economy of the local community whose livelihoods depend on coastal ecotourism.

Abstract

Ovens or artificial/mechanical drying devices are tools used in educational and research activities in laboratories that function for sterilization, drying, and storing samples or processed products. This research modifies the tangkring oven with an innovative use of electricity. The background of the study is because there is no drying device and small sample storage with a small number of samples. The modification aims to make a replacement device as a dryer and sample storage in the laboratory. This study used an experimental method, and the data were analyzed descriptively. The oven that has been modified using a tangkring oven has an inner dimension of length =36 cm; width=36 cm; height =32 cm, heat source from 150-watt halogen lamps totaling two pieces, and a 12 cm diameter fan, the outer part of the tool has a length = 42.5 cm; width = 38 cm; height = 38 cm, equipped with legs and four wheels with a height = 85 cm. Temperature testing was carried out on each shelf with a thermometer as a temperature measuring instrument, with a temperature range of 30-60⁰C. The time required to reach a constant temperature is 0.5 to 20 minutes, and the temperature difference between the regulated temperature and the temperature achieved on the tool ±2ºC shows the results obtained are still within tolerance, the error value is still within tolerance ±5% indicates the results of the tool system performance is not disturbed. From the observations made, it is concluded that the modified tangkring oven can be used as a drying device and sample storage with a faster time and using limited samples for laboratory activities.
