Abstract

The solid phase bioslurry (sludge) had the potential to be used as organic fertilizer. However, the NPK content in it did not meet SNI standards. This research aimed to study the effect of adding rice straw and fish meal to cow dung substrate for anaerobic processing, on the NPK content of the sludge produced and biogas production. Two digesters were used, which functioned as a control and a codigestion digester. Initially, in both digesters, starter breeding was carried out in batches. After the starter had grew well, then the substrate along with water was fed continuously at 88 mL/day in each digester, and an output of 88 mL/day was also produced. Analysis of COD, sCOD, VFA concentrations, and measurements of the pH values of feed and output were carried out every 3 days. Biogas volume measurements were carried out every day. The process was stopped when conditions were steady. At the end of the process, an analysis of the NPK content in the sludge and the methane content in the biogas were carried out. The results showed that biogas from codigestion content almost no methane. However, the sludge contained NPK within the range of SNI standard. Keywords: Biogas, Cow dung, Fish meal, Rice straw, Solid bioslurry fertilizer.

Abstract

Fruit is an important source of essential vitamins and minerals required to maintain human health. However, the relatively high cost of fruit often limits access among rural communities, particularly those with low- to middle-income levels. One practical and sustainable approach to improving household fruit availability is the cultivation of fruit plants in pots (tabulampot), which can provide a continuous supply of fresh fruit while also enhancing the aesthetic value of home environments. In Kediri Village, the availability of bioslurry, an organic fertilizer generated as a by-product of biogas digesters, offers an additional advantage for tabulampot cultivation by reducing fertilizer costs and promoting environmentally friendly agricultural practices. This community service program aimed to: (1) increase public awareness of the importance of daily fruit consumption, (2) disseminate knowledge and appropriate technology related to tabulampot cultivation, and (3) promote the utilization of bioslurry as an organic fertilizer. The program was implemented through community outreach, practical training sessions, and continuous mentoring until the plants reached the fruiting stage. The results demonstrated that the program was successfully implemented with active participation and strong enthusiasm from community members. Participants contributed labor, gardening equipment, and logistical support throughout the activities. Student involvement also provided valuable opportunities for experiential learning, knowledge transfer, community engagement, and the development of social awareness. The program outputs included the establishment of fruit and vegetable plants as pilot demonstrations for bioslurry application, the preparation of technical and financial reports, and the development of scientific manuscripts for publication. Overall, the program enhanced community capacity in sustainable fruit cultivation and promoted the productive utilization of locally available organic resources.
