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.

Abstract

Geographically, Buleleng Regency in North Bali has high potential coastal resources, with a coastline length reaching 157.05 km. 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

Tilapia (Oreochromis niloticus) aquaculture has high economic value and rapid growth; however, the high cost of commercial feed necessitates the use of more economical and nutritionally adequate alternative feed ingredients, such as fermented papaya leaves (Carica papaya). This study aimed to evaluate the effect of different fermentation durations of papaya leaves in commercial feed on the growth and survival rate of tilapia and to determine the optimal fermentation time. This study employed an experimental method using a Completely Randomized Design (CRD) consisting of four treatments and three replications: treatment A (control without fermentation), treatment B (3 days fermentation), treatment C (5 days fermentation), and treatment D (7 days fermentation). Tilapia fingerlings measuring ±5–7 cm with an initial weight of ±3–4 g were reared for 30 days at a stocking density of 20 fish per tank. The observed parameters included weight gain and survival rate, while the water quality parameters measured were temperature, pH, dissolved oxygen (DO), and ammonia. The data were analyzed using a One-Way ANOVA test followed by Duncan’s multiple range test. The results showed that the addition of fermented papaya leaves had a significant effect (P < 0.05) on the weight gain of tilapia, but no significant effect (P > 0.05) on the survival rate. The best treatment was obtained at 7 days of fermentation, with an average weight gain of 19.53 g and a survival rate of 100%. Therefore, a fermentation duration of 7 days for papaya leaves in commercial feed is considered the most optimal time to enhance the growth of tilapia without affecting their survival rate.
