Utilization of Quality Organic Fertilizer at P4S Sari Sedana, Badung, Bali

ABSTRACT


Background
The village, located in Abiansemal District, Badung, has significant potential in the agricultural sector.The village is surrounded by rice fields, drylands, and plantations, covering 200 hectares, much of which remains underutilized [1].However, the use of organic waste as fertilizer is still not optimal, resulting in low agricultural productivity and a lack of community awareness regarding environmental sustainability.Through this Community Service Program (CSP), it is expected that enhancing understanding and implementation of high-quality organic fertilizer usage can boost agricultural productivity and positively impact the people of Selat Village.
This CSP activity focuses on developing simple technology for the production and utilization of high-quality organic fertilizers.In addition, it includes strengthening the business management of the P4S Sari Sedana farmer group, aiming to integrate existing natural resources more optimally [2][3].The organic fertilizers produced through this initiative are expected to increase the farmer group's income and add value to organic waste by converting it into environmentally friendly fertilizer products.This effort also supports the green economy concept, a sustainable economic development model in agriculture [4][5].
Geographically, Selat Village has extensive farmland and drylands with significant potential for organic fertilizer production.However, the P4S Sari Sedana farmer group, consisting of 20 members, although already equipped with fertilizer processing facilities, has not yet been able to produce high-quality organic fertilizer.They still employ traditional methods in fertilizer management and crop cultivation, leading to the production of raw, suboptimal fertilizer for agricultural use [6].Therefore, there is a need to enhance capacity and skills in producing high-quality organic fertilizer and in cultivating crops organically. https://doi.org/10.29165/ajarcde.v8i3.489

High-quality organic fertilizer offers substantial benefits to agriculture.It can improve the physical and chemical properties of the soil [7][8], and enhance plant growth [9][10][11][12][13].By producing and utilizing compost from organic waste through simple fermentation techniques and nutrient addition, the farmer group in Selat Village is expected to increase sustainable agricultural production.Furthermore, this activity aims to add economic value for farmers by transforming organic waste into high-value fertilizer.

Objective
Given the existing challenges, the main objectives of this CSP activity are: (1) to empower the farmer group to increase the added value of organic waste processed into high-quality organic fertilizer; (2) to transfer technology for high-quality organic fertilizer production, thereby improving the group's understanding and skills; and (3) to strengthen the farmer group through training in business management and marketing of highquality organic fertilizer products.By achieving these goals, Selat Village is expected to optimize its potential, support sustainable agricultural development, and enhance the well-being of the local community.

Place and Time of Implementation
The implementation of community service was carried out in the P4S Sari Sedana Group, Selat Village, Abiansemal District, Badung Regency, Bali Province, at an altitude of 400 m above sea level.Taking place from April to August 2024.

CSP Method
The Participatory Action and Learning System (PALS) method is used in community service activities in Selat Village.This method aims to make partner groups the object of community service activities through various forms such as education, training, counselling, as well as coaching and mentoring [14].The PALS method is implemented in several stages: awareness phase, capacity building phase, mentoring and institutionalization phase [15].
The awareness Phase is an initial activity that aims to raise awareness among the target audience of partner groups regarding the importance of formulating high-quality organic fertilizers to increase agricultural production and farmer income.The method used at this stage is the Focus Group Discussion (FGD) approach, namely discussions and questions and answers related to the manufacture of high-quality fertilizers and improving the fertility of agricultural land so that partners gain a complete understanding and awareness of the benefits of high-quality organic fertilizers to increase agricultural production.To determine the level of success of this CSP, before the FGD, questions related to the CSP topic were distributed to determine the insights of CSP participants, then at the end of the CSP activity, the same questions were given to determine the increase in understanding of CSP participants.
The Capaciting Phase is the stage of involves the active participation of partner groups in managing and developing their organic fertilizer businesses.At this stage, the preparation of tools and materials and the transfer of technology for making highquality organic fertilizers, and their application to horticultural crops (vegetables, chilies, tomatoes, onions, etc.), as well as business management and marketing practices are carried out.The process of making high-quality fertilizers: a) Materials used: organic fertilizer from chicken manure waste, NPK fertilizer, rice husk biochar, Trichoderma, and dolomite.b) Tools used: scales, measuring cups, buckets, hoes, rakes, sprayers, tarpaulins, black and silver plastic mulch.c) Making 100 kg of high-quality fertilizer.60 kg of organic fertilizer, 30 kg of rice husk biochar, 7 kg of NPK fertilizer, 1 kg of Trichoderma, and 2 kg of dolomite are required.d) High-quality organic fertilizer is ready to be packaged and applied as a planting medium for horticultural plants (vegetables, chilies, tomatoes, onions) on farmers' land to increase agricultural yields.
The mentoring phase (Scaffolding) is a mentoring activity for partners during the implementation of the program activities.At this stage, monitoring and evaluation will also be carried out related to the activities that have been carried out: a) Monitoring will be carried out by the Warmadewa University Community Service Institute.b) Evaluation is carried out by comparing the achievement of success indicators before and after the implementation of the program, analyzing deficiencies and obstacles during the program implementation process, and finding solutions to existing problems so that the program implemented is truly effective optimal, and synergistic.
