Perubahan iklim secara signifikan mengubah komunitas mikrob tanah. Mikrob memiliki banyak peranan penting dalam tanah, khususnya dalam meningkatkan ketersediaan dan penyerapan hara. Tujuan dari penelitian ini adalah menganalisis populasi bakteri termofil dari mata air panas dan menganalisis kemampuan bakteri termofil tersebut dalam melarutkan P. Tahapan penelitian terdiri dari pengambilan sampel air dan tanah dari Desa Toya Bungkah, Kintamani, Bangli dengan teknik purposive sampling. Isolasi bakteri termofil dari sampel tanah dan air dengan dilution method. Bakteri hasil isolasi kemudian diuji patogenitas (hemolisis dan hipersensitif). Isolat bakteri yang lolos uji patogenitas diuji lebih lanjut kemampuannya dalam melarutkan P pada medium Pikovskaya cair. Berdasarkan 5 lokasi sampling tanah dan air di sekitar pemandian air panas menunjukkan populasi tertinggi didapatkan dari lokasi 2 (Tanah di sekitar pancoran air panas). Jumlah populasi bakteri pada lokasi 2 adalah 1,7 x 105 CFU/g. Jumlah isolat pada lokasi tersebut adalah sebanyak 3 isolat. Hasil uji hemolisis menunjukkan bahwa dari 13 isolat yang didapatkan empat isolat terdeteksi tidak menyebabkan hemolisis gamma, satu isolat menyebabkan hemolisis alpha dan delapan isolat menyebabkan hemolisis beta. Uji hipersensitif pada tanaman tembakau menunjukkan semua isolat memberikan reaksi negatif atau tidak adanya reaksi hipersensitif. Berdasarkan lima isolat yang diuji lebih dalam melarutkan P, hanya satu isolat yang dapat melarutkan P yaitu isolate AP1 (27,93 ppm). Kemampuan melarutkan P yang tergolong tinggi.

This Community Partnership Program (CSP) conducted in Desa Selat, Kecamatan Abiansemal, Kabupaten Badung, has achieved significant advancements in organic agricultural development. The program focused on the implementation of both hard and soft technologies. Hard technologies included the development of high-quality organic fertilizers using local waste materials such as livestock manure, biochar, Trichoderma, NPK fertilizers, and dolomite, processed with simple equipment. These innovations addressed local waste management issues and enhanced agricultural productivity. Soft technologies involved comprehensive training on production management, business operations, and marketing strategies, which empowered the P4S Sari Sedana Group with essential skills for sustainable operation. The program demonstrated high relevance to local needs, effectively transforming waste into valuable resources and introducing environmentally friendly production methods. It also fostered active community participation and generated substantial environmental and economic benefits, including increased soil fertility and reduced reliance on chemical fertilizers. The project produced several key outputs: high-quality organic fertilizer, enhanced community skills, scientific publications, intellectual property registration, and online media coverage. Future sustainability will be supported through institutional capacity building, market expansion, product innovation, and ongoing monitoring and evaluation.

This research aims to obtain the best mixture of rabbit fertilizer with manure and the response to the best chili varieties. This research is a factorial experiment, with a basic randomized block design (RAK) with 2 factors being tried. The first factor with 3 levels: K 0 = no manure, K 1 = rabbit manure + cow manure, K 2 = rabbit manure + chicken manure. Second factor with 3 chili varieties: V1= Rawita, V2= Ori 212, V3= Caliber and repeated 3 times. K1 gave the highest value for the fresh weight of harvested fruit per plant, namely 250.63 g. The Caliber V3 variety gave the highest value for the fresh weight of harvested fruit per plant, namely 252.87 g.

This applied research aims to evaluate the effectiveness of the fermentation of broiler chicken manure as a method of fly control in Selulung Village, Kintamani, Bangli, Bali. The broiler chicken manure fermentation method involves mixing chicken manure with other ingredients, including microorganisms from EM4 and cow manure that has been left for one month, and water to dissolve molasis. The mixture is then fermented for three months. The results of the service show that the fermentation of broiler chicken manure as citrus plant fertilizer can reduce the number of flies around the garden and the surrounding environment. In addition, the fermentation of broiler chicken manure can also reduce unpleasant odors and improve environmental quality. The result demonstrates that fermenting a mixture of 1 part chicken manure and husk, 1 part cow manure, 0.01 part EM4, and 0.01 part molasses, dissolved in 0.05 parts water, can be an effective and environmentally friendly method for controlling flies in Selulung Village.

Chrysanthemum (Chrysanthemum sp.) is one of the ornamental flower commodities that has high economic value. A significant problem for farmers in cultivating chrysanthemums is the presence of Thrips sp. and Aphis sp. pests. Thrips sp. is an insect pest that attacks plants, while Aphis sp. is an aphid pest. Both of these pests can cause significant losses by directly damaging leaves, reducing plant growth, and affecting flower quality. Conventional pest control methods, such as the use of chemical insecticides, can have negative impacts on the environment and human health, and can cause pest resistance to these chemicals. Several types of weeds, such as Echinochloa crus-galli, Panicum repens, Euphorbia hirta, and Ageratum conyzoides, are known to contain active compounds with insecticidal properties, including tannin content. The purpose of this study was to determine the effect of the combination of weed solution and its concentration in controlling Thrips sp. and Aphis sp. pests on chrysanthemums. The research design employed a Factorial Randomized Block Design, conducted in both the field and a greenhouse, with two factors: Factor I, which was a Combination of weed solutions, and Factor II, which was the concentration of the weed solution. The production data obtained were analyzed using Analysis of Variance, followed by the BNT or Duncan 5% distance test. The quality data of chrysanthemum flowers were compared with SNI 01-4478-1988. The variables observed included the intensity of pest attacks, stem diameter, leaf diameter, plant height, and the fresh weight of the plants.

Tangkas Village, located in Klungkung District, Bali, holds significant potential for organic waste utilization through the activities of the Satwa Winangun Livestock Farmer Group. This group processes cow manure and household waste into organic fertilizer. Despite contributing to waste management and sustainable agriculture, several challenges remain, including suboptimal fertilizer quality, limited application of appropriate technologies, and issues related to packaging, marketing, and product certification. This study aims to (1) improve the quality of organic fertilizer derived from household waste and cow manure through technology transfer and the use of local materials, and (2) enhance the product's added value through business management assistance, marketing strategies, packaging improvements, and certification facilitation. The research outcomes are expected to contribute to increased agricultural productivity, more efficient waste management, and improved competitiveness of organic fertilizer products at both local and regional levels.
