Abstract

Data Badan Pusat Statistik (BPS) menunjukkan jumlah pengangguran di Kabupaten Kapuas menduduki peringkat pertama dengan jumlah pengangguran terbanyak di Kalimantan Tengah pada tahun 2023. Cara yang dapat dilakukan untuk mengatasi permasalahan tersebut adalah dengan menggiatkan kegiatan kewirausahaan ekonomi hijau. Di banyak negara, konsep kewirausahaan ekonomi hijau telah diintegrasikan ke dalam kurikulum sekolah dalam upaya meningkatkan wawasan berwirausaha siswa. Oleh karena itu kegiatan Pengabdian Kepada Masyarakat melalui pendampingan kewirausahaan ekonomi hijau produk hidrogel aromaterapi berbahan miyak atsiri dari tumbuhan, dilaksanakan di SMAN 1 Kuala Kapuas berdasarkan metode community-based approach. Kegiatan pengabdian melalui 4 tahapan utama, yaitu Identifikasi masalah, Perencanaan, Pelaksanaan pelatihan dan evaluasi. Data hasil evaluasi kegiatan menunjukkan bahwa setelah siswa dan siswi SMAN 1 Kuala Kapuas mengikuti kegiatan, mereka mampu melakukan ekstrasi minyak atsiri, membuat produk hidrogel aromaterapi dan memahami konsep kewirausahaan ekonomi hijau yang dapat diaplikasikan dalam kehidupan sehari-hari.

Abstract

Tropical peat forests of Kalimantan harbor diverse wood-decaying fungi with strong ligninolytic potential, yet their functional enzymatic characteristics remain poorly documented. This study prospectively examined the physiological expression of laccase production in native fungi isolated from the Universitas Palangka Raya peat swamp forest, Central Kalimantan. Three stable pure cultures were obtained: MIPA 2 (Ganoderma sp.), MIPA 4 (Trametes sp. 1), and MIPA 8 (Trametes sp. 3). All isolates produced extracellular laccase but showed clear differences in growth and enzyme productivity. Growth analysis revealed distinct radial expansion rates, with MIPA 2 exhibiting the fastest mycelial growth (13.64 mm/day). The faster radial growth of MIPA 2 suggests higher metabolic activity and biomass formation, which may contribute to its superior laccase production compared to the other isolates. Qualitative screening on syringaldazine-amended PDA also confirmed extracellular laccase activity in all isolates, with activity levels ranging from weak (+) to strong (+++). Quantitative assays in potato dextrose broth and modified glucose–peptone medium revealed strong nutrient-dependent regulation of laccase biosynthesis, with MIPA 2 reaching 93.71 U/L on day 21. The pronounced stimulation by organic nitrogen indicates ecological adaptation to acidic, nutrient-limited peat environments and distinguishes these isolates from many previously reported Ganoderma and Trametes strains that typically require external inducers for high activity. These findings demonstrate that peat swamp ecosystems represent not only a geographic source but also a reservoir of fungi with distinct ligninolytic expression profiles and potential biotechnological relevance.
