Peran MOL sebagai dasar komponen pupuk, mikroorganisme tidak hanya bermanfaat bagi tanaman juga bermanfaat sebagai agen dekomposer bahan organik, limbah pertanian, limbah rumah tangga dan industri. Penelitian ini dilatar belakangi dengan banyaknya limbah buah-buahan yang tidak termanfaatkan, limbah bonggol pisang yang dibiarkan menumpuk tanpa dilakukan pengolahan menjadi lebih bermanfaat, keong mas yang selalu dianggap sebagai hama pada tanaman dan rumen sapi yang terbuang begitu saja dan upaya mengatasi ketergantungan terhadap pupuk dan pestisida kimia dapat dilakukan dengan meningkatkan peranan mikroorganisme. Penelitian ini bertujuan untuk menghasilkan bioaktivator kompos dan mikroorganisme yang terdapat pada mol. bahan yang digunakan dalam pembuatan MOL adalah bonggol pisang, limbah buah-buahan , keong mas, rumen sapi, urin sapi, air kelapa , air cucian beras (leri), terasi, gula merah untuk MOL I sedangkan Untuk MOL II hanya dibedakan dengan menggunakan gula putih. Pembuatan bioaktivator dilaksanakan di Laboratoriuam Produksi Politeknik Pertanian Negeri Samarinda. Bioaktivator dibuat dengan cara difermentasikan. Fermentasi bahan-bahan MOL I dan MOL II pada hari ke sepuluh seluruh permukaan mol telah ditumbuhi oleh benang-benang berwarna putih, dan berbau aroma tape. Sedangkan hasil identifikasi mikroorganismen pada bioaktivator pada kombinasi MOL I terdapat 4 jenis bakteri, yaitu Clavibacter, Agrobacterium, Clostridium, Pseudomonas berfluorescens, sedangkan untuk MOL II terdapat 3 jenis bahteri yaitu Pseudomonas berfluorescens, Erwinia dan ClavibacterKata Kunci : Bioaktivator; mikroorganisme lokal; limbah buah-buahan; bonggol pisangThe role of MOL as a basic component of fertilizer, microorganisms not only beneficial to plants are also useful as decomposers agents of organic materials, agricultural waste, household waste and industry. This research is based on the amount of untreated fruit waste, the waste of banana hump which is left to accumulate without the processing becomes more useful, the golden snail which is always considered as a pest on crops and cattle rumen that just wasted and efforts to overcome the dependence on fertilizer and chemical pesticides can be done by increasing the role of microorganism. This study aims to produce bioactivators of compost and microorganisms found in moles. the ingredients used in the manufacture of MOL are banana sticks, fruit waste, golden snail, cow rumen, cow urine, coconut water, rice laundry water (lery), terrace, brown sugar for MOL I whereas For MOL II only differentiated by using sugar white. Preparation of bioactivators carried out in the Laboratory of Production Polytechnic of Agriculture State of Samarinda. Bioactivators are made by fermentation. Fermentation of MOL I and MOL II materials on the tenth day of the entire surface of the mole has been overgrown with white threads, and smells of tape. Fermentation of MOL I and MOL II materials on the tenth day of the entire surface of the mole has been overgrown with white threads, and smells of tape. While the results of microorganisms identification on bioactivator in combination of MOL I there are 4 types of bacteria, namely Clavibacter, Agrobacterium, Clostridium, Pseudomonas berfluorescens, while for MOL II there are 3 types of Pterudomonas fluorescens, Erwinia and Clavibacter

Abstract. Rusmini, Manullang RR, Daryono. 2017. Development of shrimp shells-based compost and plant-based pesticide using bioactivators from Golden Apple Snails and their effects on the kenaf plant growth and pest population. Nusantara Bioscience 9: 260-267. Kenaf (Hibiscus cannabinus L) cultivation generally uses chemical fertilizers and pesticides to increase production despite the adverse effects of those chemicals toward environmental ecosystem. Meanwhile, there are a lot of unutilized wastes produced from agriculture and fishery. This study aimed to develop the best bio-activator from Golden Apple Snails and spices to decompose the shrimp shells waste. The bioactivator was utilized for the production of plant-based pesticide to control pests in kenaf plant, and shrimps-shells-based composts to improve kenaf plant growth. This study employed a Randomized Block Design with two factorials. The first factor was the shrimp shells-based composts (K) which consist of three levels, and the second factor was the plant-based pesticide (P) which also consists of three levels. Each of experiment was repeated twice. Thus, in total there were 18 treatments. The shrimp shells-based composts had a pH value of 8.79, Potassium (K) 8.13 %, organic carbon (C) 17.45%, Nitrogen (N) 3.62%, Phosphorus (P) 2.27%; Magnesium (Mg) 0.59%, and Calcium (Ca) 7.64%; and a C/N ratio of 4.82. Kenaf plant height at 6 and 9 weeks after planting (WAP) showed significant differences upon the shrimp shells-based composts treatments. At 6 weeks after planting, kenaf plant diameter showed significant differences upon the composts treatment, while at 9 weeks after planting, the plant diameter indicated significant differences upon both the compost and plant-based pesticide applications. Pest populations that were present in kenaf plants were caterpillars, bugs, and beetles.

Golden snail is a snail which is commonly found in rice fields which can cause damage to rice plants. The golden snail is known as a pest of rice plants because it can damage thousands of hectares of rice seedlings at an early age in a short period of time but will be beneficial if it is managed as a microorganism. Local microorganisms are microorganisms used as starters in the manufacture of solid organic fertilizers and liquid fertilizers as well as fast growing decomposers in agricultural systems. The purpose of this study was to determine the quality of local microorganisms in producing bioactivators from various amounts of different ingredients in the golden snail. This research was conducted in four locations, namely the Agronomy Laboratory of the Samarinda State Agricultural Polytechnic (manufacturing bioactivators), the Production Laboratory of the Samarinda State Agricultural Polytechnic (composting), and at Sucopindo (nutrient analysis). This research used three treatments including golden snail bioactivator I (A1), golden snail bioactivator II (A2), and golden snail bioactivator III (A3). Based on the results of the study, it can be concluded that treatment A3 (Keong Mas III Bioactivator) gave the best results for the parameters of temperature, color, odor and C-organic local microorganism (MOL) for the golden snail, while treatment A1 (Bioactivator Keong Mas I) gave the best results for the parameters Ph.

One of the efforts to continuously increase lettuce production is by using hydroponic technology. Hydroponics is a way of farming without using soil media but using water or porous materials. Nutrient Film Technique (NFT) including hydroponic farming methods. In this system, some of the roots of the plants are submerged in water that contains fertilizer and some are above the surface of the water with a continuous 24 hours of circulation. The research was conducted from June to November 2020. The research was carried out on the Hydroponic Roof Top of the Red Building. Plantation Cultivation. This research method used a non-factorial randomized block design (RBD), the treatment of 1100 ppm AB Mix nutrition at the age of 1-14 days, 1300 ppm from the age of 21-28 days, 1500 ppm at the age of 29 - 35 days and B2 = Fertilizer Growmore 1100 ppm at the age of 1 - 14 and 1300 ppm from the age of 21 - 28 days, 1500 ppm at the age of 29 - 35 days Each treatment consists of 20 sample plants.The results showed a significant difference in the application of AB Mix fertilizer to Growmore fertilizer from week 1 to week IV on plant height increase, number of leaves and wet weight or yield on lettuce plants.
