Abstract

ABSTRACT  Although Andisols is the best soil type to support plant growth, overuse of Andisols soil type can degrade soil quality. Gunung Tujuh District of Kerinci Regency's Jernih Jaya Village, there is an Andisols land use location. Soil quality is negatively impacted by land management practices, which disregard land sustainability, soil, and water conservation measures. To understand the physical characteristics of Andisolss in various land uses in Jernih Jaya Village, it is vital to examine the effects of different tillages and land uses. The stages were (1) preparation of primary data (taking soil samples) and secondary data (making maps), (2) survey (preliminary survey and main survey), (3) data processing and interpretation of data resulting from analysis of soil samples and surveys. Based on an examination of various physical attributes of Andisols in different land used within Jernih Jaya Village, Gunung Tujuh District, Kerinci Regency, it could be inferred that the physical properties of Andisols were deemed favorable. The results indicated that the area was used for vegetables, plantations, secondary forests, and paddy fields, with slope classes ranging from 0-3%, 3-8%, and 8-15%, sandy loam with a crumb structure in all land used, high water content, moderate to high total pore space, low to medium volume weight, and high organic matter were all present. When compared to other land uses, paddy fields had the highest organic matter content (22.10%), highest moisture content (124.89%), highest total pore space (79.39%), and lowest bulk density (0.57 g/cm3).

Abstract

Tunas Makmur Farmers Group I of Ibru Village, Mestong District, Muaro Jambi Regency, Jambi Province has not yet made optimal use of a large amount of agricultural, plantation and industrial waste, due to farmers' lack of knowledge about biochar and its use to improve soil productivity. For this reason, the implementing team offers an easy, cheap and sustainable solution to manage and utilize abundant sources that can be used as a source of biochar. The objectives of implementing this community service activity can be achieved through: 1) counseling and training about the benefits of biochar to improve the physical and chemical properties of soil, 2) demonstration of making biochar from agricultural, plantation and industrial waste using drum pyrolysis, 3) assistance in calculating the dose given and application in the field through demonstrations on partner land on how to use biochars properly. Partners in this activity earn their main income from being food crop and plantation farmers. Agricultural, plantation and industrial waste is usually piled up on land and wasted because farmers do not yet have knowledge about the benefits of this waste. After conducting socialization and education through counseling and demonstrations about making biochar from agricultural and industrial waste, farmers have the motivation to use this waste as a source of soil carbon and as a soil conditioner.
