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.

Abstract

This study explores the fabrication of a cellulose/HKUST-1 composite derived from purun (Lepironia articulata), a wetland biomass abundant in cellulose and promising as an eco-friendly feedstock for advanced materials. HKUST‑1, a copper-based metal-organic framework known for its high porosity, suffers from reduced stability in humid environments. To address this limitation, a composite integrating purun-derived cellulose with HKUST‑1 was synthesized and subsequently characterized using Fourier Transform Infrared (FTIR) spectroscopy. Cellulose was isolated via alkaline delignification and peroxide bleaching with a yield of 26.68%. HKUST-1 was synthesized using a solvothermal method, producing a turquoise-blue material with a yield of 70.96%. The composite was prepared using an ex-situ method, resulting in a green-colored product with a yield of 85.90%. FTIR analysis confirmed HKUST-1 formation through the disappearance of the C=O band (~1719 cm⁻¹) and the appearance of COO⁻ bands (~1560-1600 and ~1450 cm⁻¹), along with Cu-O vibration (~725 cm⁻¹). FTIR analysis of the composite revealed the presence of diagnostic peaks attributable to both cellulose and HKUST‑1, confirming successful incorporation without compromising structural integrity. Notably, the O‑H stretching band appeared broadened and slightly shifted, indicating hydrogen-bond interactions between cellulose and HKUST-1. These results demonstrate that purun-derived cellulose is a sustainable matrix for HKUST-1 with potential in adsorption applications.
