Raw materials for compost making, local microorganisms (MOL), and biochar are widely available in the District of Ingin Jaya. So far, municipal waste, agricultural waste, and household waste have not been managed properly, are seen as worthless products, and cause environmental and aesthetic problems. These wastes can be converted into economically viable products such as compost, MOL and biochar. However, the community's mastery of science and technology is still very limited to converting these materials into products of economic value. Therefore, PKMBP activities were carried out through a participatory approach which was followed by field schools. The goal is to improve the capabilities and skills of the partner group consisting of members of farmer groups, PPL, PPL self-supporting in mastering the science and technology of composting, and MOL and Biochar making. The result achieved was that the PKMBP activity could increase the community's capacity in mastering the concepts, manufacturing, and application techniques of compost, MOL, and Biochar using simple technology. The community can use these products as environmentally friendly fertilizers, increase land productivity and farm efficiency. This activity can also improve the quality of waste into products of economic value, increase community turnover and overcome health problems and environmental aesthetic values.

Abstrak. Tanah adalah mekanisme karakteristik untuk pengembangan tanaman. Tanah memberi unsur-unsur hara sebagai makanan tanaman untuk perkembangannya. Tanah terbentuk dari bahan berupa mineral dan bahan organik, air dan udara yang tersusun dalam ruangan yang membentuk tubuh tanah. Hasil jalannya proses perkembangan pembentukan tanah, maka terbentuklah perbedaan sifat kimia tanah, fisik, biologi dan morfologi tanah (Hakim,et all, 1986). Tanah yang diusahakan untuk bidang pertanian memiliki tingkat kesuburan yang berbeda-beda.Adapun tujuan dari penelitian ini adalah untuk mengevaluasi kandungan hara pada dua lokasi budidaya tanaman serewangi yang menyebabkan perbedaan pertumbuhan di dua lokasi tersebut. Pengelolaan tanah secara tepat merupakan faktor penting dalam menentukan pertumbuhan dan hasil tanaman yang akan diusahakan. Penentuan ketersediaan hara tanah diawali dengan survey pendahuluan, pengambilan sampel tanah dilapangan dan selanjutnya dilakukan analisis sampel tanah dilaboratorium dan terakhir dilakukan pengolahan data dengan mengacu pada tabel kriteria interpretasi sifat-sifat kimia tanah menurut puslittanak (2003). Berdasarkan hasil analisis laboratorium, menunjukkan bahwa kandungan hara di dua lokasi budidaya tanaman serewangi tidak menunjukkan perbedaan yang jauh berbeda, relatif hampir sama dengan kandungan hara yang rendah. Perbedaan pertumbuhan tanaman serewangi pada dua lokasi budidaya disebabkan oleh perbedaan topografi lahan yang agak berbeda serta cara pengelolaannya, yang menyebabkan perbedaan pertumbuhan tanaman di dua lokasi tersebut.Evaluation of Nutrient Availability in Two Locations of Serewangi Cultivation in Lamteuba, Seulimuem District, Aceh BesarAbstract. Soil is a characteristic mechanism for plant development. Soil provides nutrients as plant food for its development. Soil is formed from materials in the form of minerals and organic matter, water and air which are arranged in a room that forms the body of the soil. As a result of the development process of soil formation, differences in soil chemical, physical, biological and morphological properties of soil are formed (Hakim, et all, 1986). Soil cultivated for agriculture has different levels of fertility. The purpose of this study was to evaluate the nutrient content of the two locations of Serewangi cultivation that caused differences in growth in the two locations. Proper soil management is an important factor in determining the growth and yield of plants to be cultivated. Determination of soil nutrient availability begins with a preliminary survey, taking soil samples in the field and then analyzing soil samples in the laboratory and finally processing data by referring to the table of interpretation criteria for soil chemical properties according to Research Center for Research and Development (2003). Based on the results of laboratory analysis, it was shown that the nutrient content in the two locations of Serewangi cultivation did not show much difference, relatively close to the same with low nutrient content. The difference in the growth of the serewangi plants at the two cultivation locations was caused by the slightly different topography of the land and the way of management, which caused differences in plant growth in the two locations.

Application of Some Sources of Organic Fertilizer on The Growth and Production of Soybean (Glycine Max L.) in UltisolAbstract. Ultisols are poor soil types with low nutrient and organic matter content. Organic matter plays an important role in increasing and maintaining soil fertility and will determine crop productivity. In this study, several sources of organic fertilizer will be applied, namely organic fertilizer from trembesi compost, cow manure, kirinyu green manure, and kirinyu compost with the indicator plant being soybean (Glycine max L.). This study aims to determine the application of several kinds of organic fertilizers on the growth and production of soybean (Glycine max L.) in Ultisol. This study used a non-factorial Randomized Block Design (RAK) consisting of four sources of organic fertilizer with 2 (two) doses of 10 tons ha-1and 20 tons ha-1 with various combinations of treatments. So there are 8 treatment combinations. The results of this study indicate that the application of several sources of organic fertilizer can increase the availability of nutrients in Ultisol and can also increase the growth and yield of soybeans. Based on the results of the final analysis of the chemical properties of the soil after being given organic fertilizer treatment, it showed that the application of organic fertilizer had a very significant effect on the increase in soil organic C, P-available soil and also had a significant effect on the yield of stem seed weight. But it does not show a significant difference in the other parameter observations. The application of organic fertilizer doses that gave a significant effect in increasing the Ultisol nutrient content and soybean yield was in the combination of cow manure treatment at a dose of 20 tons ha-1.

Limbah cair yang dihasilkan berupa Palm oil mill Effluent (POME) air buangan kondensat (8-12%) dan air hasil pengolahan (13-23%). Dalam1 ton hasil kelapa sawit dapa tmengeluarkan limbah yang tidak bisa di pakai atau beracun mencapai 600-700 kg limbah cair. Meningkatnya kualitas tanah dan sifat-sifat Ultisol seperti sifat fisik, biologi dan kimia tanah memerlukan suatu pengelolaan tanah dengan memberikan bahan organic seperti limbah cair kelapa sawit (sludge) yang tepat dan efisien sehingga dapat meningkatkan produktifitas tanah, karena bahan organic yang terkandung dalam limbah cair pabrik kelapa sawit baik untuk sifat kimia tanah dan dapat dipergunakan sebagai pengganti pupuk kimia untuk pupuk bibit kelapa sawit. Dalam penelitian ini menggunakan pendekatan penelitian kuantitatif dan didapatkan bahwa Pemberian limbah cair kelapa sawit dapat mempengaruhi sifat kimia tanah Ultisol dengan adanya peningkatan beberapa parameter kimia tanah baik dari pH dari 4,94 menjadi 5,26 setelah pemberian limbah cair kelapa sawit dengan pemberian 2400 ml per polibag (L4) dan Adapun parameter lainnya.Effect of Palm Oil Mill Liquid Waste Use on Changes in Chemical Properties of Ultisols and Growth of Oil Palm Seeds (Elaeis guineensis Jacq)Abstract. Oil palm (Elaeisguineensis Jacq.) is one of the most important vegetable oil-producing plants. Palm oil production per hectare is the highest production compared to all other vegetable oil producing plants. The industry in the palm oil sector emits a lot of fiber and residues from processing such as liquid waste and solid waste. The liquid waste produced is in the form of Palm oil mill Effluent (POME), condensate waste water (8-12%) and treated water (13-23%). In 1 ton of palm oil products can produce waste that can not be used or toxic up to 600-700 kg of liquid waste. Improving soil quality and Ultisol properties such as soil physical, biological and chemical properties requires a soil management by providing appropriate and efficient organic matter such as palm oil waste (sludge) so as to increase soil productivity, because of the organic matter contained in liquid waste. Palm oil mills are good for the chemical properties of the soil and can be used as a substitute for chemical fertilizers for fertilizers for oil palm seeds. In this study using a quantitative research approach and it was found that the application of palm oil effluent can affect the chemical properties of Ultisol soil with an increase in several soil chemical parameters, both from pH from 4.94 to 5.26 after administration of palm oil effluent by giving 2400 ml per polybag (L4) and other parameters.

Abstrak. Biochar merupakan padatan berupa arang yang kaya karbon (C) melalui proses pembakaran tidak sempurna dengan minimum oksigen (pyrolisis). Penambahan bahan organik dapat mempercepat proses pemulihan kualitas lahan serta meningkatkan kekuatan tanah memegang air sehingga kandungan unsur hara juga meningkat. Pemanfaatan kompos berpengaruh terhadap pasokan hara tanah, perubahan sifat fisik, biologi, dan kimia tanah, karena syarat tanah sebagai media tumbuh tanaman membutuhkan kondisi fisik dan kimia yang baik. Aplikasi biochar dan kompos dilakukan untuk meningkatkan kesuburan dan ketersediaan air tanah untuk memenuhi kebutuhan tanaman.Pada penelitian ini digunakan tanaman jagung (Zea mays L) sebagai indikator tanaman. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan pola Non Faktorial terdiri dari kombinasi biochar dan kompos limbah pertanian dengan 9 perlakuandan 3 kali ulangan, maka didapatkan 27 bedengan percobaan. Hasil di lapangan didapatkan pemberian biochar dan kompos limbah pertanian tidak berpengaruh terhadap perbaikan sifat fisika tanah pada lahan kering diduga karena sifat fisika yang sulit berubahdalam waktu yang singkat, namun pemberian biochar dan kompos limbah pertanian dapat meningkatkan atau berpengaruh terhadap pertumbuhan serta hasil tanaman jagung yang mana nilai tertinggi terdapat pada perlakuan A8 (15 ton ha -1 biochar dan 20 ton ha -1 kompos imbah pertanian) hal ini diduga pada dosis tersebut pemberian kompos menyumbangkan unsur hara yang cukup bagi tanaman.Utilization of Biochar and Agricultural Waste Compost to Improve Soil Physical Properties, Growth and Yield of Corn on Dry LandAbstract. Biochar is a solid in the form of charcoal rich in carbon (C) through an incomplete combustion process with a minimum of oxygen (pyrolysis). The addition of organic matter can accelerate the process of restoring land quality and increase the strength of the soil to hold water so that the nutrient content also increases. The use of compost affects the supply of soil nutrients, changes in the physical, biological, and chemical properties of the soil, because the soil requirements as a medium for plant growth require good physical and chemical conditions. Applications of biochar and compost are carried out to increase fertility and availability of groundwater to meet plant needs. In this study, maize (Zea mays L) was used as plant indicator. This study used a Randomized Block Design (RBK) with a non-factorial pattern consisting of a combination of biochar and agricultural waste compost with 9 treatments and 3 replications, so 27 experimental beds were obtained. The results in the field showed that the application of biochar and agricultural waste compost did not affect the improvement of the physical properties of the soil on dry land, presumably due to the physical properties that were difficult to change in a short time, but the application of biochar and agricultural waste compost could increase or affect the growth and yield of maize plants. where the highest value was found in the A 8 treatment (15 tons ha -1 biochar and 20 tons ha -1 agricultural waste compost).
