Abstract

Masalah sampah, khususnya sampah plastik, merupakan isu global yang mendesak dan berdampak signifikan terhadap lingkungan dan kesehatan masyarakat. Di SMKN 4 Kerinci, Kabupaten Kerinci, Provinsi Jambi, sampah plastik dari kemasan makanan dan minuman serta sisa-sisa makanan organik menjadi masalah utama. Plastik yang sulit terurai dapat berubah menjadi mikroplastik, yang berpotensi menjadi racun bagi manusia. Kurangnya kesadaran siswa mengenai dampak sampah, ditambah dengan kebiasaan membuang sampah sembarangan, memperburuk kondisi tersebut. Meskipun ada upaya pengolahan seperti pembuatan kerajinan dari plastik, solusi ini masih terbatas. Penggunaan ecobrick menjadi salah satu solusi potensial. Melalui kegiatan pengabdian ini, diharapkan masalah sampah di sekolah dan masyarakat dapat diatasi, lingkungan menjadi lebih bersih, serta kesadaran dan partisipasi dalam pengelolaan sampah meningkat. Hasil dari kegiatan pengabdian ini dapat dilihat dari respon peserta yang sangat positif serta antusiasme dan keaktifan peserta yang tinggi dalam mengikuti pelatihan. Peserta juga dapat mengatasi dan meminimalisir serta memiliki niatan dalam mengoptimalkan sampah plastik yang ada dilingkungan sekolah dan masyarakat untuk didaur ulang menjadi produk yang memiliki nilai guna.

Abstract

Peat water, commonly found in peatland regions, often poses a challenge as a water source due to its high content of iron and natural organic matter (NOM). This research investigated the development and application of bentonite–chitosan nanocomposites as an effective adsorbent for reducing iron metal and NOM concentrations in peat water. Chitosan was synthesized from tilapia fish scales through demineralization, deproteinization, and deacetylation processes, then characterized for moisture content (7.4%), ash content (5.4%), and functional groups using FTIR spectroscopy. Bentonite was thermally and chemically activated with sulfuric acid to increase its adsorption capacity. Nanocomposites were prepared with varied bentonite-to-chitosan ratios (90:10, 70:30, 50:50) using sodium tripolyphosphate (STPP) as a crosslinker. FTIR and XRD analyses confirmed the formation of nanocomposites and revealed structural changes post-adsorption, including reduced crystallinity and increased particle size. Adsorption studies showed that the 90%Bt-10%Ch3 formulation achieved the highest iron removal efficiency (68.6%) with an adsorption capacity of 0.084 mg/g. Meanwhile, the 50%Bt-50%Ch3 formulation demonstrated the highest NOM removal efficiency (36.8%) with a capacity of 36.80 mg/g. The results indicate that bentonite is more effective for iron adsorption, while chitosan plays a key role in removing NOM due to its amine and hydroxyl functional groups. This study highlights the potential of utilizing fishery waste and natural minerals to produce low-cost, eco-friendly nanocomposites for improving water quality in peatland environments.
