Abstract

Belawan Ocean Fishing Port (PPS) is one of the largest fishing ports in North Sumatra. PPS Belawan aims to increase the income of fishing communities through the provision of fishing port facilities and infrastructure. The study aims to analyze the optimization of the level of utilization of basic, functional and supporting facilities at the Belawan Ocean Fishing Port and to determine the condition of these facilities. The latest conditions in the field through field surveys show that there are several facilities whose utilization levels are not optimal and whose conditions are not good, such as the port pool. The study was conducted at PPS Belawan, North Sumatra from December 15, 2024 to January 15, 2025. The method used in this study is the survey method. The data collected in the study are primary data in the form of interviews with several sources whose daily activities are related to port facilities, namely basic facilities, functional facilities, and supporting facilities. The data analysis used is descriptive which explains the condition of the port facilities and the level of utilization of port facilities from several facilities which can be calculated systematically. The results of the research show that the Belawan ocean fishing port facilities whose level of utilization can be calculated are still not optimal, even far from optimal, while the conditions of all the facilities required to be in ocean fishing ports, namely those divided into basic facilities, functional facilities and supporting facilities are in quite good condition, and can support port operations quite well.

Abstract

This study aims to determine the spawning techniques of Leptobarbus hoevenii fish at the Sungai Gelam Freshwater Aquaculture Center (BPBAT). Activities include maintaining prospective broodstock, selecting mature broodstock, injecting ovulation hormones, and the spawning process, stripping, egg handling, water quality monitoring to highlight its importance, and embryo development. Ovaprim hormone injections were administered to the female broodstock four times and once to the male broodstock to stimulate ovulation. The stripping process was carried out after ovulation and was followed by dry mixing of eggs and sperm before being spread into the hatching tank. The results showed a fertilization rate of 63,08% and a hatching rate of 9,73%, which were influenced by gamete quality and the physiological condition of the broodstock. Observations of embryogenesis showed developmental stages ranging from morula, blastula, gastrula, to organogenesis before the eggs hatch into larvae. Water quality parameters during the study were in the optimal range for spawning, namely pH 7,24–7,77, temperature 27–30,5°C, and DO 3,53–5,58 mg/L. The results of this study explain that the success of Hoven’s carp fish seeding is highly dependent on the readiness of the broodstock, the application of artificial spawning techniques, and good water quality management.

Abstract

The sea in Indonesia covers 75% of its total land area. According to data from the Ministry of Marine Affairs and Fisheries (2019), Indonesia has approximately 5.8 million km² of water area out of a total territory of 7.81 million km². The biodiversity in Indonesia's coastal areas is utilized by coastal communities in their daily lives. Coastal resources also have potential in the health sector, such as seagrass, macroalgae, and taurine, which can be used as raw materials for natural medicine. The purpose of this study is to analyze the antioxidant potential based on the IC50 value of taurine, ethanol extracts of the seagrasses Enhalus acoroides and Cymodocea rotundata, as well as the macroalgae Padina australis and Sargassum duplicatum. The method used is the antioxidant activity assay using DPPH (2,2-Diphenyl-1-picrylhydrazyl). The results of this study indicate that, after testing with DPPH, only the ethanol extract of Cymodocea rotundata had an IC50 value of < 200 µg/mL, specifically -652.95 µg/mL, whereas the IC50 values of taurine, the ethanol extract of Enhalus acoroides, and the ethanol extracts of the macroalgae Padina australis and Sargassum duplicatum were > 200 µg/mL, indicating no antioxidant activity. In conclusion, only the ethanol extract of Cymodocea rotundata has the potential to be a candidate for antioxidant raw material.
