Abstract

Foodborne bacteria cause food spoilage, usually Staphylococcus aureus and Escherichia coli. Thus, synthetic preservatives are employed in food preservation to prevent food spoilage caused by microorganisms. Excessive use of synthetic preservatives can cause disease. Bio-oil has become a natural preservative because of its high phenolic content. However, bio-oil still requires purification because the initial bio-oil (grade 3) still contains carcinogenic compounds that are dangerous for consumption. Therefore, this study aims to determine the components of the bio-oil compound after purification and its effectiveness as an antibacterial. Durian shell (DS) is pyrolyzed in a heating reactor without oxygen at a temperature of 330–600ºC (flow rate 6ºC/minute) with a 2-3 cm material size. Furthermore, bio-oil purification includes stages of filtration using activated zeolite, fractional distillation at 70–200ºC (grade 2), and filtration using activated charcoal (grade 1). Bio-oil purification includes stages of filtration using active zeolite and activated charcoal (grade 2), and fractional distillation at a temperature of 150–200ºC (grade 1). Based on Gas Chromatography-Mass Spectrometry (GC-MS) analysis, grade 2 and grade 1 contain the major compounds 1,4-dimethyl-1h-imidazole and acetic acid. The research showed that bio-oil grades 1 and 2, when used at a 30% concentration, exhibit antibacterial strong effects against Staphylococcus aureus and Escherichia coli. These findings suggest that bio-oil grades 1 and 2 could be valuable natural preservatives.

Abstract

Penerapan teknologi produksi biopestisida dari limbah kulit buah kakao (KBK) menggunakan metode pirolisis merupakan solusi inovatif dalam mengelola limbah pertanian menjadi produk bernilai tambah yang ramah lingkungan. Penelitian ini bertujuan untuk mengubah limbah KBK menjadi biopestisida melalui proses pirolisis. Tahapan pengabdian ini meluputi, sosialisasi, strategi pemecahan masalah, pengenalan prototipe pengolahan KBK, dan pelatihan. Partisipasi mitra yaitu kelompok tani dan PT. Hasfarm Niaga Nusantara yang dilaksanakan di Desa Ponanggo Jaya Kecamatan Lambandia Kabupaten Kolaka Timur Provinsi Sulawesi Tenggara. Hasil produksi biopestisida KBK menunjukkan kemampuan untuk menghambat pertumbuhan jamur pada benih tanaman kakao serta selama masa penyimpanan 6 hari benih kakao memiliki daya tumbuh sebesar 60%. Hasil evaluasi menunjukkan bahwa pengembangan teknologi pirolisis untuk produksi biopestisida dari limbah KBK memiliki potensi besar untuk memberikan manfaat yang signifikan bagi pertanian dan lingkungan. Diperlukan penelitian lebih lanjut dan kerjasama antara pemerintah, industri, dan petani untuk mengembangkan teknologi ini secara lebih luas dan efektif.
