Abstract

Avicennia marina, a mangrove plant, is renowned for its medicinal properties, particularly its antibacterial potential. Phytochemical analysis of the plant revealed the presence of bioactive compounds such as alkaloids, terpenoids, and flavonoids, which are known to contribute to its antibacterial effects. This study investigates the antibacterial activity of Avicennia marina leaf extract against Staphylococcus aureus and Escherichia coli. The research employed three main methods: preparation of Nutrient Agar (NA) and Nutrient Broth (NB) as growth media, extraction of bioactive compounds from Avicennia marina leaves, and antibacterial testing at concentrations of 0.1 and 0.2 grams on each medium. The results showed that the leaf extract effectively inhibited the growth of Staphylococcus aureus when using NB, with inhibition zones measuring 6.47 mm and 12.26 mm, indicating a bacteriostatic effect. In contrast, no inhibition zones were observed when using NA, suggesting that the growth medium plays a critical role in determining antibacterial effectiveness. These findings underscore the significant potential of Avicennia marina leaf extract as a natural antibacterial agent, particularly against Staphylococcus aureus, and highlight the importance of selecting suitable media and testing methods. This study paves the way for future research into the development of Avicennia marina-based nutraceuticals and pharmaceuticals, with potential applications in healthcare and bacterial infection management.

Abstract

Tanjung Perak is a bustling port with significant shipping and loading/unloading activities, which can contribute to marine environmental pollution, including oil spills. These spills have serious impacts on the marine ecosystem, as oil spreads based on water conditions once released into the environment. Therefore, effective oil spill response measures are essential to mitigate the adverse effects of such incidents. This study aims to assess the preparedness of the Oil Spill Response (OSR) team at PT Lamong Energi Indonesia in preventing and controlling oil spills at Tanjung Perak Port. Conducted from February to April 2023, the research involved 15 members of the OSR operations team at PT Lamong Energi Indonesia as respondents. Data analysis utilized index analysis based on four key preparedness parameters: 1) knowledge and attitudes, 2) emergency response plans, 3) early warning systems, and 4) resource mobilization capacity. The results revealed that the OSR team's preparedness index was 75, indicating a "prepared" status. Notably, the team members with more than two months of service exhibited the highest preparedness level, with an index score of 86, classified as "very prepared." These findings suggest that the OSR team at PT Lamong Energi Indonesia is generally well-prepared, with longer-serving members demonstrating greater readiness in oil spill response.

Abstract

Waste from fish scales, skin and bones in the fishing industry are currently only used as fish meal or handicrafts. Fish waste is very abundant, especially in fish that are widely consumed by the public, such as little tuna or Kawakawa (Euthynnus affinis). Therefore, innovations are needed in processing fish scales, skin and bones waste, namely as ingredients in making fish glue. Fish glue is an adhesive resulting from the extraction of fish scales, skin and bones which contains collagen, which can be hydrolyzed in hot water and dilute acid to form fish glue. The aim of this research is to determine the effect of using fish skin, scales and bone waste materials on the results of glue products. The research method is by extracting bones, scales, and skin of Kawakawa using 5% CH3COOH solution in a ratio of 1: 1, then filtered to obtain fish glue. This study used two treatments: the use of raw materials of bones, scales, and fish skin (Sample-1) and fish skin and scales only (Sample-2). The results of research showed that Sample-2 showed a higher total rendement or yield than Sample-1. In addition, Sample-2 has a more intense color than Sample-1. It is necessary to demineralize the raw materials (fish waste) to increase the results of collagen extraction.

Abstract

Styrofoam waste is an inorganic material that cannot decompose and will continue to accumulate if not recycled. Styrofoam has relatively light properties, can withstand heat, and is resistant to corrosives. In coastal and marine environments, styrofoam waste can cause significant pollution and damage to marine ecosystems. However, when used in the production of paving blocks, styrofoam waste has a disadvantage: it results in a low compressive strength value. To address this, coconut fibers are used to strengthen the paving blocks because coconut fibers have tensile strength, making them durable, lightweight, and elastic. The purpose of this study was to determine the mechanical properties of paving blocks made with a mixture of styrofoam and coconut fibers (Cocofoamblocks). The method used in this study is a quantitative approach with experimental research. The results of the water absorption test show that the absorption rates of the Cocofoamblocks is in the range of 17.55% to 19.28%. This indicates that the Cocofoamblocks can be categorized as suitable for use. The results of the compressive strength test show that the average value for sample BT1 is 0.5 MPa, while samples BT2 and BT3 have values of 1.1 MPa and 2.4 MPa, respectively. Based on these results, it is evident that the compressive strength of the Cocofoamblocks can be categorized as unsuitable for use. This is because the Cocofoamblocks lack coarse aggregates, and the excessive amount of water used in the mixture during production further reduces their compressive strength. This study contributes to efforts to reduce waste pollution in coastal and marine areas, as well as to creating environmentally friendly solutions that can enhance the sustainability of development in coastal regions.

Abstract

Bawean Island, located in Gresik Regency, is highly vulnerable to the impacts of climate change due to its coastal position. One of the significant impacts is sea level rise, which increases the risk of tidal floods. Effective and timely decision-making is essential to mitigate and manage these risks. This study focuses on mapping vulnerability and assessing the level of community knowledge regarding climate change to evaluate the island's susceptibility. The objectives include identifying data, measuring community knowledge levels, and analyzing vulnerability. The findings reveal that 323 hectares fall into the vulnerable category, while 1 hectare is classified as very vulnerable. The community's knowledge level is predominantly high, with 73% of respondents scoring high and 27% moderate. Inundation predictions for the next 20 years, based on a sea level rise of 3 cm per year, estimate an inundation area of 319,398 hectares in 2024 with a sea level rise of 2.64 cm. By 2044, the highest high-water level (HHWL) of 4.00 cm could inundate an area of 442,625 hectares. These findings underscore the urgent need for adaptation strategies to mitigate the risks of tidal floods and enhance the resilience of coastal communities on Bawean Island.
