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.

Low feed quality in fish culture reduces fish digestibility; therefore, the feed quality needs improvement. An effort to increase the nutritional value of feed is by adding probiotics. However, on the one hand, feed residues that form organic and inorganic compounds can affect water quality in the cultivation medium; on the other hand, suitable water quality plays a vital role in fish farming. Adding probiotics containing microorganisms, such as EM4 probiotics, can benefit aquaculture businesses. Probiotic EM4 (Effective Microorganisms), one of the probiotics given in fish farming, is a brown liquid with a sweet and aromatic taste, containing a mixed culture of fermentative microorganisms, namely lactic acid bacteria (Lactobacillus casei) and yeast (Saccharomyces cerevisiae). This research is a literature review with data from various relevant articles assembled from Google Scholar, accredited journals, textbooks, and theses. In conclusion, it can be presumed that using EM4 probiotics in aquaculture has beneficial effects, including improving the quality of aquaculture water, increasing the growth rate of fish, suppressing pathogenicity, and reducing feed conversion. ABSTRAK Kualitas pakan yang rendah dalam akuakultur menyebabkan daya cerna ikan menjadi kurang optimal. Oleh karena itu, kualitas nutrisi pakan yang lebih baik perlu ditingkatkan. Upaya yang dapat dilakukan untuk meningkatkan nilai gizi pakan adalah dengan menambahkan probiotik. Namun di satu sisi, residu pakan yang membentuk senyawa organik dan anorganik dapat mempengaruhi kualitas air pada media budidaya; di sisi lain, kualitas air adalah salah satu faktor penting yang berperan dalam budidaya ikan. Penambahan probiotik yang mengandung mikroorganisme, seperti probiotik EM4, dapat menguntungkan usaha perikanan budidaya. Probiotik EM4 (Effective Microorganisms), salah satu probiotik yang diberikan dalam usaha budidaya ikan, merupakan cairan berwarna coklat dengan rasa manis dan aromatik, yang mengandung kultur campuran mikroorganisme fermentatif yaitu bakteri asam laktat (Lactobacillus casei) dan ragi (Saccharomyces cerevisiae). Penelitian ini merupakan literature review (kajian literatur) dengan data yang bersumber dari berbagai artikel relevan yang diperoleh dari google schoolar, jurnal terakreditasi, text book, skripsi, dan lain-lain. Berdasarkan hasil kajian, dapat dikatakan bahwa penggunaan probiotik EM4 dalam perikanan budidaya memberikan dampak menguntungkan, antara lain: memperbaiki kualitas air akuakultur, meningkatkan laju pertumbuhan ikan, menekan patogenitas, dan memperkecil konversi pakan. Kata Kunci: Akuakultur, konversi pakan, laju pertumbuhan ikan, probiotik, probiotik EM4

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.

Cultivation of silk worms (Tubifex sp.) is one of the important components in supporting the aquaculture sector, especially as a natural food for larval and fry fish. This study aims to assess the differences in the growth of silk worms fed with feed made from organic waste in the form of papaya residue and fermented feed made from tofu pulp, bran, sugar, brown sugar, and EM4. The study used an experimental method with a complete randomized design (CRD) consisting of two treatments, each with three replicates. Parameters observed included silk worm biomass growth, feed conversion efficiency, survival rate, and feed residue left in the media. The results showed that feeding papaya waste provided faster growth and body division of silk worms compared to fermented feed. In addition, the media fed with papaya feed showed lower levels of feed residue, resulting in a more stable culture medium with low ammonia levels. In contrast, the fermented feed left white granules that were difficult to decompose and became a source of ammonia accumulation. Thus, papaya waste feed is more recommended in the environmentally friendly and efficient cultivation of silk worms.
