Abstract

This community service activity was carried out by the Chemistry Study Program of Tribuana Kalabahi University (UNTRIB) in collaboration with the Altar Youth Classis, with the aim of increasing the knowledge and skills of young people in utilizing local organic materials to make bokashi-type solid fertilizer. Alor Regency has abundant natural resource potential, but the still traditional agricultural system and dependence on inorganic fertilizers are major challenges. Through this activity, young people were trained to process organic materials such as goat manure, lamtoro leaves, banana stems and other organic materials as well as household waste with the help of effective microorganism fermentation (EM4) into environmentally friendly and economically valuable bokashi fertilizer. This activity included the delivery of materials, a question and answer session about fertilizer making, and direct mentoring by lecturers and students of the UNTRIB Chemistry Study Program. The results of this activity showed an increase in the participants' understanding and skills in the fermentation process, organic waste management, and the application of chemical principles in agricultural practices. Thus, this training is expected to encourage youth independence in the agricultural sector while strengthening collaboration between universities and the community in realizing sustainable agriculture based on local wisdom.

Abstract

The development of slow-release fertilizers (SRFs) has gained increasing attention as an efficient approach to enhance nutrient utilization while minimizing nutrient losses and environmental impacts. In this study, biochar–chitosan composites were employed as encapsulating materials for urea and Fe to produce SRF beads. The beads were synthesized through ionic gelation in NaOH solution, followed by swelling tests and structural characterization using Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The swelling analysis demonstrated that the most effective formulation was obtained from the composition containing 3 g of biochar and 3 g of urea, achieving the highest swelling capacity of  92% after 48 h. This result indicates that the biochar–chitosan matrix provides sufficient porosity and water affinity to support nutrient retention and release. FTIR spectra confirmed the presence of characteristic functional groups of biochar, chitosan, urea, and Fe, verifying the successful incorporation of all components into the composite beads. Furthermore, XRD analysis revealed a predominantly amorphous structure, as evidenced by broad peaks in the 2theta range of 20°–60°. However, sharp crystalline peaks were also observed at 2theta approximately 29.1° and 33.9°, corresponding to urea, and at 2theta approximately 40°, attributed to crystalline phases of urea and Fe. These results suggest that the structural configuration of the beads combines both amorphous and crystalline phases, which may contribute to controlled nutrient release behavior. Overall, the findings demonstrate that biochar–chitosan encapsulation is a promising strategy for developing efficient SRFs with enhanced swelling properties and structural stability, offering potential for sustainable agricultural applications.

Abstract

The Pancasila Student Profile Strengthening Program (P5) is an initiative designed to shape students' character holistically, in accordance with the noble values ​​of Pancasila, which are the foundation of national and state life. One concrete step in implementing this program is through community service activities carried out by students of the Chemistry Study Program, Tribuana Kalabahi University, at Wolwal High School. This activity not only aims to provide technical knowledge regarding ecoenzyme production, but also plays a role in strengthening the P5 dimensions which include mutual cooperation, independence, critical thinking, creativity, and global diversity. In this activity, Tribuana Kalabahi University students integrate the chemistry theory they have learned with the direct practice of making ecoenzymes from organic waste. The creation of ecoenzymes, which is an environmentally friendly solution in waste management, is an effective medium for instilling students' understanding of the importance of environmental awareness and the practical application of chemical concepts. Through this activity, students are not only involved in the technical process of ecoenzyme production but are also empowered to think critically about innovative, creative, and sustainability-based environmental solutions. They are trained to work collaboratively in groups, reflecting the spirit of mutual cooperation, while simultaneously developing independence in carrying out practical tasks. Furthermore, this activity also provides a space for students to appreciate diversity, strengthen open attitudes, and deepen their sense of responsibility towards environmental issues, which aligns with the values ​​of global diversity in P5.
