Abstract

Improving teacher competency is essential for enhancing the overall quality of education. Teachers play a strategic role in implementing effective learning processes. To support this, a training program was held from October 5th to 7th, 2024, at the Manise Hotel, Ambon City, Maluku Province. The training aimed to develop research, writing, and publication skills among teachers and educational personnel. The event was attended by 50 participants, including two education personnel and members of the Maluku Province Teacher Mobilization Team. The instructors for this training were Mr. La Mansur, Mr. Deni Hadiana, Mr. Misbah Fikrianto, Mrs. Rini Anita Putri, and Mr. Alfi Hasan. This initiative was supported by the Maluku Provincial Teacher Mobilization Centre, which mobilized the Mobilizing Action Community (KORA-KORA), known for its strong commitment to improving educational services, strengthening quality, and implementing various programs. The training used a combination of methods, including lectures, group discussions, collaborative learning, and project development. The goal was to make research enjoyable, encourage creative writing, and support participants in publishing their work. According to post-training observations, around 95% of the participants expressed satisfaction with the training and felt it was appropriate for their needs. Participants also hoped that similar activities would continue in the future. This continuous development of competencies ensures that teachers and educational personnel can sustain improvements in their professional capabilities.

Abstract

This study aims to examine the mechanical properties, surface morphology, and biodegradability of polyvinyl alcohol-potato starch biocomposites with lemon peel powder as a filler. The biocomposites were produced by solution casting with 1%, 2%, and 3% fillers of lemon peel powder. Mechanical properties were tested to determine tensile strength in accordance with ASTM D882. The addition of lemon peel powder increased tensile strength as the percentage content increased. The highest tensile strength was 4.82 MPa in polyvinyl alcohol-potato starch biocomposites containing 3% lemon peel powder. This indicates that lemon peel powder effectively improves bonding with the matrix and produces stronger interfacial bonds. However, the flexibility of the biocomposites decreased with increasing lemon peel powder content, as indicated by a decrease in elongation. Furthermore, the biodegradation of the biocomposites showed that the biocomposite with the highest lemon peel powder content (3%) exhibited the fastest degradation rate, reaching 65.22% after 15 days of testing. These results indicate that the presence of lemon peel powder improves the mechanical properties of the biocomposite without reducing its biodegradability. These findings indicate that biocomposites made from polyvinyl alcohol and potato starch with lemon peel powder are a promising sustainable plastic alternative, combining strength, flexibility, and degradability.
