Abstract

The current reliance on chemical fertilizers has caused many problems in agricultural practices, such as the decline in soil quality and crop resistance to environmental stress. Farmers are encouraged to use chemical fertilizers, due to the lack of efficiency of nutrient absorption in plants which results in a lack of productivity of agricultural products. This research aims to review in depth the role of Mycorrhizal fungi in increasing the efficiency of nutrient uptake by plants. The research method used is the literature review method to explore more deeply the role of mycorrhizal fungi in increasing the efficiency of plant nutrient uptake. The results stated that mycorrhizal fungi have great potential as microorganism partners in increasing plant nutrient uptake. With its ability to expand the root absorption area, and enhance plant growth, improve soil structure and reduce pollution, mycorrhiza can contribute significantly to agricultural sustainability.

Abstract

Agriculture is a strategic sector that has the ability to overcome world problems, such as natural climate transition and land degradation. The use of Plant Growth-Promoting Rhizobacteria (PGPR), such as Bacillus and Pseudomonas, is one promising solution. These bacteria play a role in increasing nutrient uptake, controlling pathogens, and stimulating the development of cultivated products. Based on the results of previous research, it is explained that Bacillus spp. are able to produce bioactive metabolites that increase plant tolerance to stress, while Pseudomonas spp. play a role in increasing systemic plant immunity. The combination of the two is proven to have a synergistic effect, increasing plant productivity by up to 25%, and improving rhizosphere health. However, challenges such as lack of technology adoption and supportive policies still hinder the widespread implementation of PGPR. This research highlights the great potential of Bacillus and Pseudomonas as biological agents in supporting sustainable agriculture.

Abstract

Character is an important aspect that influences the development of an individual's personality in the campus environment. As a place for intellectual, social, and emotional growth, the campus plays a strategic role in shaping students' character. Good character not only supports academic success but also shapes students' attitudes and behaviors in their social lives. In the campus environment, students are faced with various challenges that test their morals and ethics, such as plagiarism, substance abuse, and violations of rules. Therefore, it is important to develop a strong and positive character through integrated character education in campus activities. Character enhancement can be achieved through both formal and non-formal learning, as well as an environment that supports the formation of such character. With good character, students will be able to face life's challenges wisely and contribute positively to society.

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
