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.

Abstract

The condition of the nest greatly determines the success of turtle egg hatching. The success of turtle egg hatching, both naturally and artificially, is influenced by several factors such as the location of the nest, the depth of the nest, vegetation conditions, environmental temperature, humidity and the surrounding environment. This study aims to see the effect of shade on the length of the incubation period and the success of green turtle egg hatching in semi-natural nests. This study was conducted at Pangumbahan Nesting Beach, Sukabumi. This study used an experimental method with the treatment of semi-natural nests placed in exposed areas and shaded areas with different depths, namely 68 (control), 30, 50, 70 and 90 cm. Measurements and observations of environmental conditions were carried out during the incubation period. Observations of hatching of hatchlings began on the 55th day of incubation and the dismantling of the entire nest was carried out on the 68th day of incubation. The results showed that in exposed areas there was no significant difference given the level of treatment on the length of the incubation period, while in sheltered or protected areas there was at least one difference in the level of treatment that had a different effect on the length of the incubation period. The fastest incubation period in exposed areas was at a depth of 30 cm and in sheltered areas was at a depth of 90 cm. Key words: incubation period, the green turtle, the success of hatching.

Abstract

Filter net is a traditional fishing gear designed as a conical bag with small-mesh netting. It operates as a passive tool, intercepting and trapping fish by leveraging the velocity of tidal currents. This study investigates the diversity and comparison of catch yields between daytime and nighttime in Pangkalan Jambi Village, Bengkalis Regency, Riau Province. Data collection consisted of fishermen's catch records. The research employed a survey method with direct field observations. The results revealed that the catch composition of the filter net in Pangkalan Jambi Village comprised 32 species. Daytime catches totalled 5,695 individuals, while nighttime catches amounted to 6,414 individuals. Commonly caught species during both daytime and nighttime included kedukang fish, lomek fish, biang fish, spiny shrimp, red shrimp, and jerbung shrimp. T-test results indicated no significant difference in catch quantities between daytime and nighttime (P > 0.05). The study concluded that the diversity index for daytime and nighttime catches was moderate, the evenness index was high, and the dominance index was low. The frequency of occurrence of the primary catch species during daytime and nighttime exceeded 50%.

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

Mangroves are well-known for their diverse benefits, with all plant parts containing beneficial bioactive compounds. This study aims to evaluate the antioxidant activity of the methanolic extract of Rhizophora apiculata mangrove leaves. Mature mangrove leaves were extracted using 70% methanol through a maceration method, and antioxidant activity was assessed using the DPPH radical scavenging assay. The results indicated that the extract exhibited inhibition percentages ranging from 56% to 91% at concentrations of 50–1000 ppm, with an IC₅₀ value of 30.86 µg/mL. These findings suggest that the methanolic extract of mature R. apiculata leaves possesses powerful antioxidant potential (IC₅₀ < 50 µg/mL).
