Abstract

The Penimbangan is one of the potential locations for underwater tourism in the Regency Buleleng, by unique dive spot. Planning and sustainable coastal development are essential for the continuity ecosystem, sea, and economy. Fish and coral studies in Penimbangan, District Buleleng, occurred from December 2022 to February 2023. Location observation shared four sites of data retrieval. The determination sites study uses purposive sampling based on the spread of coral naturally. Data was collected by Underwater Photo Transect (UPT) for coral and Underwater Visual Census (UVC) for fish. Transect area coral 50m long with quadratic transect (58cmx44cm), and classified categories using CPCe software. Transect area fish of 350 m2 (length 70 m, limit right and left 2.5 m), identified fish to level species. The most studied habitat associations in coral reefs are coral (HC) and fish in coral assemblages. Percentage composition substrate basis in Penimbangan, namely dead coral with algae (106.74), coral (90.27), and sand (70). Lifeform coral is found in as many as ten types; the most are CM (39.00), CE (23.20), and ACS (10.07). A total of 17 families with 70 reef fish species were recorded in this study. The family with the most species is Pomacentridae (25), followed by Chaetodontidae (9) and Labridae (8). The composition of fish will vary according to the type of habitat. Different coral habitats covered by benthic influence the abundance of certain trophic levels of reef fish in an area of water.

Abstract

This study aims to evaluate the effect of carrageenan addition on the physicochemical properties of fruit slice jam made from Sonneratia caseolaris. This mangrove fruit contains 0.32% pectin, making it a potential raw material for jam production. However, conventional jam has limitations in practicality, leading to the development of fruit slice jam, which has a compact, non-sticky, and plastic-like texture. The study employed a Completely Randomized Design (CRD) with four treatments: P0 (control, 2% pectin), P1 (1.25% carrageenan), P2 (1.50% carrageenan), and P3 (1.75% carrageenan), each replicated five times. The physical parameters analyzed included hardness, cohesiveness, adhesiveness, and springiness, while the chemical parameters consisted of moisture content, ash content, reducing sugar, and pH. Data were analyzed using one-way ANOVA at a 95% confidence level, followed by Duncan's Multiple Range Test (DMRT). The results indicated that increasing carrageenan concentration significantly (P<0.05) decreased adhesiveness, springiness, and moisture content, while hardness, cohesiveness, ash content, reducing sugar, and pH increased. Thus, carrageenan addition significantly influences the physicochemical properties of fruit slice jam made from S. caseolaris, offering a promising innovation for fruit-based jam products

Abstract

Marine debris is a solid material that is intentionally or unintentionally left in the waters and can directly threaten the condition and productivity of water areas. Tirta Ayu Beach and Balongan Beach are tourist destinations that are threatened by marine debris. The presence of tourists on the beach is very beneficial for increasing regional and community income, but it can also result in an increase in the generation of waste generated so that a lot of this waste accumulates and is distributed to various places and has a negative impact on the waters. This study aims to determine the species composition, weight, density, and distribution of marine debris at Tirta Ayu Beach and Balongan Beach. Sampling was conducted at 8 research stations, then classified and analyzed based on UNEP and KLHK provisions. The results showed that the types of marine debris found on Tirta Ayu Beach and Balongan Beach included plastic, plastic foam, rubber, paper and cardboard, wood, glass, cloth, and other materials. Plastic is a type of marine debris dominating Balongan Beach (89%) and Tirta Ayu Beach (81%). The highest density value of marine debris based on quantity and weight was found on Tirta Ayu Beach with a value of (5.0 ± 1.9 items/m2) and a weight of 25.8 ± 16.3 gram/m2.

Abstract

The mangrove apple (Sonneratia caseolarisi) has potential as an alternative food source due to its high nutritional and antioxidant content. This study aims to analyze the effect of storage duration on mangrove apple-based fruit slices' microbiological and chemical quality by adding rosella extract, focusing on Total Plate Count (TPC) value, antioxidant activity, and proximate analysis. The slices were made by adding 50% rosella extract based on the weight of the fruit pulp and were tested during storage at 0, 7, 14, 21, and 28 days. The research methods included TPC testing to count microorganisms, antioxidant activity testing using the DPPH method, and proximate analysis to determine moisture, fat, protein, ash, and carbohydrate content. The results showed that TPC values increased significantly with longer storage time, with the highest increase in the fourth week. Antioxidant activity also decreased over time, indicating the degradation of antioxidant compounds due to oxidation. Proximate testing revealed increased moisture and fat content, while protein, ash, and carbohydrate levels decreased as storage duration increased.
