Abstract

Community service is crucial in addressing local challenges and empowering communities through knowledge and practical solutions. Tuwung Village, located in Kahayan Tengah Subdistrict, Pulang Pisau Regency, Central Kalimantan, includes 1,297 hectares of village forest within a convertible production forest area. With a population of 727 people, most of whom work in the agricultural sector, the community faces challenges related to using environmentally harmful chemical fertilizers. Despite the village's rich biodiversity, applying liquid organic fertilizers remains uncommon. Purun plants, a local resource, serve as a promising raw material for liquid organic fertilizer production due to their nutrient-rich composition, which benefits sustainable agriculture. This program focused on training the Tuwung community in utilizing purun as a raw material for liquid organic fertilizer to improve agricultural productivity while reducing dependence on environmentally damaging chemical fertilizers. Evaluation through pre- and post-tests demonstrated significant increases in participants' knowledge, skills, and interest in sustainable agricultural practices, with 88% of participants expressing a strong interest in using pure-based liquid organic fertilizer in the future. The program aligns with the United Nations' Sustainable Development Goals (SDGs), particularly Goal 2 (Zero Hunger) and Goal 12 (Responsible Consumption and Production), by promoting sustainable farming practices and encouraging the responsible use of local resources.

Abstract

The fishing industry in Palangka Raya City, Central Kalimantan Province, has great potential for development. However, farmers face problems related to feed availability and prices, as well as limitations in digital marketing. This community service program aims to provide skills to the “Berkat Bersama” Business Group through training in independent fish feed production using local materials with automatic machines and digital marketing training. The activities were carried out in a participatory manner, including preparation and coordination, procurement of materials, assembly of feed printing equipment, module development, dissemination of information on the importance of quality feed and the use of local materials, and training on marketing strategies using digital media. Monitoring and evaluation were conducted through pre-tests, post-tests, and participant testimonials. The pre-test results showed that the majority of participants were in the “Poor Understanding” (75%) and “No Understanding” (12.5%) categories. After the training, there were no more participants in these two categories, while 12.5% of participants reached the “Fair Understanding” category, 25% “Understanding,” and 25% “Very Understanding.” Participant testimonials reinforce that this program is useful as a means to increase independence in feed supply, expand the marketing network for fishery products, and strengthen the competitiveness and sustainability of freshwater fish farming businesses in Palangka Raya.

Abstract

The presence of dye waste in the environment can affect ecosystems and humans. Therefore, this study aims to degrade Remazol Black B dye waste, which has been widely used as a synthetic dye in the batik and textile industries. The electrochemical degradation of RBB waste has been successfully carried out using carbon electrodes from battery waste. The influence of voltage and electrolysis time, as well as decolorization efficiency, has also been analyzed using a UV-Vis spectrophotometer. Based on the results, the optimum voltage and time for RBB degradation were obtained at 15 volts for 20 minutes with an efficiency of 100%. Meanwhile, at voltages of 5 and 10 volts, the efficiencies were 70% for 60 minutes and 100% for 30 minutes, respectively. The use of carbon electrodes from battery waste offers a new alternative for easy and efficient color waste treatment.
