Abstract

Polylactid Acid (PLA) is a biodegradable polymer made from natural ingredients so it is safe to use for biomaterials. The purpose of this study was to determine the biodegradation characteristics of the addition of chitosan powder and Hydroxyapatite to PLA. There were 4 variations in this study, namely PLA 100 (pure PLA), PLA-chitosan-Hydroxyapatite 94-3-3 (Composite 1), PLA-chitosan-Hydroxyapatite 94-0-6 (Composite 2), PLA-chitosan-Hydroxyapatite 94-6-0 (Composite 3). Samples were prepared using the extrusion method to form filaments, then the filaments were injected with a temperature of 170-190°C and an injection pressure of 5-6 bar. Characterization was carried out using the Immerse Test, FTIR Test, and SEM-EDS Test. The results of the Immerse Test showed an increase in sample mass of 1.04%, 1.1%, 1.05% and 1.14% respectively. FTIR test results did not show any new functional groups in the composite. The results of the SEM test indicated the presence of Na and Cl deposits on the sample surface as evidenced by the results of the EDS test that all samples contained Na and Cl elements. So that the weight gain occurs because the three materials are not chemically mixed which easily separate and cause cavities, these cavities are filled with HBSS liquid.

Abstract

The Community Service (CS) program took place in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, approximately 100 km southwest of Malang City. The target group for this program includes small and medium enterprises (SMEs) engaged in koi fish spawning. Our partners face several challenges, primarily the reliance on aeration pumps powered by the national electricity grid (PLN) to supply oxygen to the ponds. The program aimed to install a 100 Wp solar panel system to generate clean energy for a low-voltage aeration pump, helping to maintain optimal oxygen levels in the pond and supporting healthy fish growth. The program successfully implemented this solar-powered aerator pump system in the pond area, providing an innovative, sustainable solution that empowers the community by integrating science and technology into fisheries. It is hoped that this program will inspire other fish farmers in Tulungagung and surrounding areas to adopt similar sustainable practices.
