Aquaculture plays a vital role in meeting the global demand for animal protein, yet the dependency on expensive imported feed ingredients remains a significant challenge. Optimizing the use of local feed ingredients is a strategic approach to enhance sustainability and cost-efficiency in fish farming. This research aims to optimize the composition of local feed ingredients to achieve 30% protein content in farmed fish feed. The formulation involves rice bran, corn bran, fish meal, and tofu dregs, selected based on local availability and protein content. The methodology includes analysis of the protein content of raw materials, formulation testing, and physical evaluation of feed. The results show that the pellets produced have nutritional quality that meets the target, good physical stability, and cost efficiency of up to 40% compared to commercial feed. This research makes a significant contribution in supporting the sustainability of the fish farming industry and reducing dependence on imported raw materials.

The pace of global environmental change and the intensification of human activities have put significant pressure on marine ecosystems, threatening the sustainability of many species that are important both for ecosystems and the economies of coastal communities. In this context, this study aims to evaluate the application of genetic technologies in the conservation of endangered marine species, focusing on environmental DNA (eDNA) monitoring, CRISPR genetic engineering techniques and population genetic analysis. The method used was a literature review that examined current academic sources related to genetic technologies and their implementation in conservation. Findings show that eDNA is a highly effective tool in species and habitat monitoring, and has been successful in specific cases such as Napoleon fish and green turtles in Raja Ampat. In contrast, CRISPR techniques offer the potential to improve the genetic resilience of species, despite significant regulatory and ethical challenges. The implications of this study emphasize the need for strong policy support and international collaboration to address these challenges and optimize the use of genetic technologies in more effective conservation strategies in the future.

This research was conducted at Malaga Beach, Siwalu Banua II Village, Gunungsitoli Idanoi District, Gunungsitoli City, North Sumatra Province, with the aim of determining the feasibility of beach tourism objects from the limiting factors of the Tourism Suitability Index Value (IKW). This research was carried out for 1 month, namely from the beginning of March to the beginning of April 2021. The method used in this research was the purposive sampling method. The analysis parameters used are depth, beach type, beach width, bottom water material, current speed, beach slope, water brightness and beach land cover. Based on the results of observations, it shows that the Malaga Beach tourist attraction has good potential because it has a wide sand beach and has not big waves. The research results show that the Tourism Suitability Index (IKW) value is 58.16% and is classified as S3 (Conditionally Suitable) level of suitability. This value provides information that the tourist attraction is in the appropriate category conditionally for the feasibility of its development. The condition for the development in question is the appropriate use of potential, namely the potential width or breadth of the beach as well as the presence of shady pine and palm trees by creating comfortable shelters such as tourist tents, gazebos, children's toys. Thus, Malaga Beach, Siwalu Banua II Village, Gunungsitoli Idanoi District, Gunungsitoli City, North Sumatra has good potential to be developed into a recreational tourism and children's play location, but is not suitable for swimming tourism.

Silkworms (Tubifex sp.) are one of the leading natural feeds that are rich in protein, essential amino acids, and fats, and have a body size suitable for consumption by fish larvae. However, its limited availability and fluctuating quality are challenges in fish hatchery activities. This study aims to optimize the direct cultivation of silk worms in tarpaulin ponds with a field experiment approach, in order to increase the quantity as natural feed. The research was conducted at Ceria Group, Tugalagawu Village, Sirombu Sub-district, West Nias Regency, from May 27 to June 15, 2025. The methods used included the use of mud media enriched with organic materials such as bran and tofu pulp, and fermentation with EM4 to increase nutrient availability. Environmental parameters such as temperature (26-28°C) and pH (6.8-7.2) were controlled during the rearing period. The results showed that organic fermentation media was able to increase worm biomass to 80-120 g/m² with a harvest efficiency of 75%. The worms produced had visual quality and nutritional content suitable as larval feed, with potential protein content of 55-60% and fat content of 13-15%. This study concludes that local fermentation-based cultivation techniques can increase the efficiency of silk worm production while supporting natural food self-sufficiency at the coastal community level.

Indonesia is the world's largest archipelagic country, providing abundant biodiversity potential. The rapid development of chemistry, phytochemistry, and pharmacology has increased the research and application of various plants in the health sector. Phytopharmaca is a standardized herbal medicine that has proven its efficacy through clinical trials. Various types of marine biota that are easy to find have been proven to contain bioactive compounds that can potentially develop phytopharmaceuticals based on biological resources. The development of phytopharmaceuticals made from marine plant raw materials has yet to be widely developed. Limiting factors often found are references to pharmaceutical standardization and the required research funding. However, this does not rule out the possibility of realizing phytopharmaceutical products from marine plants that meet standards and clinical trials. Therefore, the aim of the explanation regarding research, types, and potential of marine biological resources in phytopharmaceuticals is to provide information and learning media.
