Abstract

Fusarium species are destructive plant pathogens responsible for severe crop losses thereby posing a critical threat to global food security. Sustainable strategies to control Fusarium-induced diseases are urgently needed due to limitations of synthetic fungicides. This study investigated the interaction of phytochemicals from potato (Solanum tuberosum), cassava (Manihot esculenta), and purple yam (Dioscorea alata) with three Fusarium proteins: LaeA, Pep2, and VeA. Protein structures were modeled and validated using stereochemical analyses, followed by molecular docking with representative metabolites, including pyrogallol, cyclogallipharaol, scopoletin, linamarin, cyanidin-3-glucoside, and peonidin-3-glucoside. Docking results showed that potato metabolites exhibited moderate binding activity, cassava metabolites displayed broader inhibitory potential, and purple yam anthocyanins demonstrated the strongest affinities (–6.7 to –7.4 kcal/mol) through multiple hydrogen bonds, hydrophobic contacts, and electrostatic interactions. Among the targets, Pep2 showed consistently stable interactions, while LaeA and VeA exhibited greater flexibility but remained responsive to anthocyanins. These findings highlight the potential of edible crop-derived phytochemicals, particularly anthocyanins and scopoletin, as eco-friendly antifungal agents. The structural basis provided here supports future experimental validation and the development of sustainable crop protection strategies.

Abstract

Warga binaan Lembaga Pemasyarakatan Kelas II B Kota Tasikmalaya memerlukan pembekalan berupa pengetahuan dan keterampilan praktis tentang budidaya pertanian berbasis vertikultur sebagai bekal menghadapi tantangan ekonomi pasca-lapas. Kegiatan pengabdian ini bertujuan meningkatkan pengetahuan dan keterampilan warga binaan melalui penerapan teknik budidaya vertikultur, penyuluhan pengolahan hasil sayuran dan pelatihan digital marketing. Kegiatan dilakukan melalui penyuluhan, pelatihan, dan pembuatan demplot dengan tahapan persiapan pra pelaksanaan program berupa koordinasi dan penyediaan sarana dan prasarana, sosialisasi, pelatihan dan penerapan teknologi serta pendampingan, evaluasi dan keberlanjutan program. Hasil program menunjukkan peningkatan pemahaman anggota kelompok sekitar 18,46% serta tersedianya produk sayuran berupa cabai, pakcoy dan selada. Respon para warga binaan sangat positif dibuktikan dengan hasil evaluasi kegiatan yang mencakup rata-rata kepuasan terhadap kegiatan berkisar puas-sangat puas. Program ini efektif mendorong para warga binaan untuk mendapatkan keterampilan yang bisa digunakan pasca keluar dari lapas.
