Abstract

The purpose of this research was to identify heavy metals in Jembrana waters and analyze water quality to determine water fertility. This study used direct observation and quantitative descriptive. Primary production, biological chemical physical parameters, and heavy metal data were collected in this study. The results showed that Jembrana waters had the highest primary productivity value of 1051.01 mgC/m3/day and the lowest value of 112.61 mgC/m3/day. Water quality in Jembrana is considered quite good. The results of this study showed that the water conditions at the observation site remained stable and within the tolerance limits for marine biota. This is due to the fact that during the sampling period, there was no significant activity from fishermen and local residents. Observations of heavy metals lead and cadmium at the study site showed that some stations exhibited values that exceeded the threshold, but these values were still acceptable for the waters. The heavy metal levels at the stations exceeded the threshold due to sewage effluents from companies and ships in the local harbor.

Bondalem Village is in Tejakula District, Buleleng Regency, in the northern part of the Island of the Gods. The condition of the coral reefs in the Bondalem Waters area is categorized as very good, with coral reef cover percentages ranging from 65.93% to 81.33%. Besides having potential for diving tourism, Bondalem Village also boasts cultural attractions and local artistic wisdom. The purpose of this research is to identify the minatourism potential in Bondalem Village from the social aspect of the community. This research uses a descriptive quantitative method. The research process begins with the preparation of a proposal and the drafting of a questionnaire, followed by data collection, data processing, and data testing before drawing conclusions from the research activities. Based on research conducted on the potential of minatourism from the social aspect of the community in Bondalem Village, Buleleng, Bali, it is concluded that Bondalem Village in North Bali, specifically in Buleleng Regency, has minatourism potential that can be developed based on cultural, economic, and environmental assessments. The analysis of cultural, economic, and environmental aspects influencing minatourism potential, based on interviews with respondents, yielded scores of 3.253, 3.256, and 3.220, respectively, indicating that respondents support the development of minatourism potential in Bondalem Village from these aspects. This research is expected to provide useful input for various parties, especially the government, the Bondalem Village authorities, and researchers, to jointly support sustainable minatourism development.

Abstract

Food safety is a crucial aspect of vannamei shrimp (Litopenaeus vannamei) aquaculture, particularly regarding the use of chemicals that may leave harmful residues. This study aims to analyze the compliance of chemical usage in vannamei shrimp farming in Tuban Regency with food safety standards. Data were collected through interviews with farmers and fish health analysts, as well as laboratory testing of shrimp samples from several pond locations. The analysis results showed that all samples from the tested sites were compliant, meaning they met the permitted residue limits. Therefore, it can be concluded that shrimp farming practices in this region have been carried out responsibly and in accordance with prevailing safety standards. This study may serve as a reference for the development of guidance and monitoring efforts toward sustainable shrimp farming in other regions.

Abstract

Padina australis is known to contain various bioactive compounds. This study examines the potential of Padina australis from Sumberkima Village, which has not been widely explored. The main objective of this research is to conduct phytochemical screening to identify the secondary metabolite profile and determine the level of antioxidant activity through the determination of the IC50 value, in order to provide a scientific data foundation for developing the potential of this seaweed, especially in the aquaculture sector. Sample extraction was performed using the maceration method with distilled water as the solvent and heating on a hot plate. The analyzed parameters were phytochemical content, which included quantitative tests for phenols, flavonoids, and tannins, and qualitative tests for saponins, alkaloids, and terpenoids, as well as antioxidant activity using the DPPH method. Data analysis was conducted descriptively to classify the strength of the antioxidant activity and the presence of phytochemical compounds. The quantitative phytochemical test results showed that the P. australis extract contained total phenols of 176.98 mg/100g, flavonoids of 101.49 mg/100g, and tannins of 5.31 mg/100g. Meanwhile, the qualitative tests showed negative results for saponins, alkaloids, and terpenoids. The antioxidant activity test results showed a very high IC50 value of 6213.2823 ppm, indicating that the antioxidant activity level of this extract is classified as very weak or inactive. This low antioxidant activity is suspected to be due to the combination of using distilled water as a solvent and an extraction method that is less effective in optimally extracting potent bioactive compounds. Therefore, further research with solvent variations or the application of modern extraction techniques is recommended.

Abstract

Sumberkima Village, Gerokgak District, Buleleng Regency has fishery cultivation potential in the form of floating net cages (KJA) as well as coastal ecosystems that support minatourism development. This study aims to determine the fishery cultivation potential that can be developed into a minatourism object and to design a sustainable fishery cultivation development model to support minatourism in Sumberkima Village. The study used a Research and Development (R&D) approach with the ADDIE model, involving 77 respondents determined using the Slovin Formula, consisting of aquaculture business actors, local minatourism managers, village officials, and tourists. Data were analyzed using multiple linear regression and SWOT (IFAS-EFAS) analysis. The results showed that fishery cultivation potential (X1) and community participation (X3) had a positive and significant effect on minatourism development (Y), while supporting facilities (X2) had no significant effect, with a coefficient of determination (R2) of 0.761. The SWOT analysis placed Sumberkima Village in Quadrant I with coordinate point (0.85 ; 1.05), indicating that an aggressive (SO) strategy is the most appropriate strategy to apply. The recommended development model integrates local potential, supporting facilities, and community participation, while still considering environmental, economic, and social sustainability aspects. Minatourism; Sumberkima Village; SWOT
