Abstract

Spinach is one of the most important needs for humans, but spinach production in Indonesia has decreased from year to year, so it needs improvement in terms of cultivation technology. The purpose of this study was to analyze the interaction between varieties of spinach and the dose of organic seaweed fertilizer on spinach production; analyzed the dose of organic seaweed fertilizer on spinach production and analyzed the effect of spinach varieties on spinach production. This study was arranged in a factorial randomized block design (RBD), which consisted of two factors, the first factor was the variety of spinach (b) which consisted of two levels, namely green spinach variety Giti Hijau (b1) and red spinach variety Giti Merah (b2), the second factor is the dose of organic fertilizer (d) which consists of 4 levels, namely control (d0), 2 mL/L water (d1), 3 mL/L water (d2), 4 mL/L water (d3). The treatment was divided into 3 blocks as repetition. Data analysis used ANOVA and follow-up test with a DMRT level of 5%. The results showed that the variety of spinach had a significant effect on plant height from 3 to 5 WAP, the number of leaves at 2 WAP and 3 WAP, and the fresh weight of spinach. Fertilizer dosage did not significantly affect plant height, number of leaves, root length, fresh weight, and dry weight of plants . There was no interaction between spinach varieties and doses of organic seaweed fertilizer on all growth parameters and production of spinach.

Abstract

This study evaluates the effectiveness of natural materials as antimicrobial agents in the treatment of freshwater fish diseases, with the aim of offering a safer and more sustainable alternative to synthetic chemicals and antibiotics. Using the literature review method, this study analyzed relevant current scientific articles. Results showed that extracts of betel leaf, neem leaf, cinnamon essential oil, basil essential oil, aloe vera, and propolis had significant antimicrobial activity against freshwater fish pathogens such as Flavobacterium columnare and Aeromonas hydrophila. Betel leaf extract and cinnamon essential oil showed inhibition rates of up to 85% and 82%, respectively. The advantages of using natural ingredients include environmental safety, reduced risk of antimicrobial resistance, and immunostimulating effects in fish. However, challenges such as ingredient availability, cost, and standardization still need to be addressed. This study suggests the development of natural ingredient-based products, standardization and quality testing, further research, and training for fish farmers. Collaboration between stakeholders is also important to reduce dependence on antibiotics. In conclusion, natural ingredients have great potential as effective and environmentally friendly antimicrobial agents in freshwater fish health management.

Abstract

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

Abstract

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.

Abstract

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.
