Abstract

Tawangmangu District, Indonesia, is located in a highland area with a cool climate and is predominantly composed of Andisol soil types, offering great potential for the development of potato crops (Solanum tuberosum L.). This study aims to examine soil physical properties suitable for potato cultivation, analyze the distribution of these properties across different slope gradients, and identify appropriate soil management strategies for the Tawangmangu area. The research employed a descriptive-exploratory approach, utilizing land map units (LMUs) that were determined through the overlay of soil type maps, rainfall data, slope gradients, and land use. The overlay resulted in 5 LMUs and 25 sampling points. Observed soil physical parameters included texture, porosity, permeability, consistency, effective soil depth, coarse material, and drainage. The land suitability assessment showed that LMUs 1, 2, and 3 were classified as S3-oa, limited by drainage, while LMUs 4 and 5 were classified as S3-oa,rc, limited by both drainage and effective soil depth. Slope gradient significantly affected moisture content (p = 0.022), bulk density (p = 0.037), particle density (p = 0.048), porosity (p = 0.032), effective soil depth (p = 0.001), and coarse material content (p = 0.032). Recommended land management efforts include the addition of organic matter, manual tillage for shallow soils, and the application of eco-drainage techniques to improve soil physical suitability for potato cultivation in Tawangmangu.

Abstract

The Sido Dadi Farmer Group in Giripurwo Village, Girimulyo District, Kulon Progo Regency generates a large amount of cocoa pod husk waste that has merely been piled around the plantations, while farming still relies on chemical fertilizers and the group has no processed products, product identity, business legality, or marketing channels. This community service program aimed to empower the farmer group through the application of appropriate technology for processing cocoa pod husk waste into compost, liquid organic fertilizer (LOF), and bioherbicide with economic value. A participatory empowerment approach was implemented in three stages, namely awareness, capacity building, and empowerment, comprising focus group discussions, training on good agricultural practices for cocoa, production training and practice, provision of production equipment, packaging design, assistance in obtaining a Business Identification Number (NIB), development of a marketing website, and marketing strategy training. Evaluation was carried out through laboratory testing of product quality and a Likert-scale empowerment questionnaire administered to 25 group members. The results show that the partner is able to produce three products from cocoa pod husk; the compost contains 25.04–27.07% organic carbon with a C/N ratio of 14.07–16.50. The group now holds an NIB under the Indonesian Standard Industrial Classification code 20124, packaging designs for three products, and the biokao.id website as a promotional medium. The proportion of members in the empowered and highly empowered categories reached 87%, whereas initially 52% of members were in the not yet empowered and less empowered categories. The program demonstrates that appropriate technology based on local waste, combined with institutional and marketing strengthening, can foster sustainable farmer group independence.
