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.

Abstract

Lemon (Citrus limon L.) is a high-value horticultural commodity with growing demand, yet national production cannot meet domestic demand. Andrau Nursery, a Micro, Small, and Medium Enterprise (MSME) in Palangka Raya, has the potential to develop lemon-based products but faces challenges such as unstable sales of fresh fruit, spoilage due to the short shelf life, and suboptimal utilization of low-grade lemons. The proposed solution is to apply dehydrator technology to create value-added products such as dried lemon slices, powder, and herbal tea, which have a longer shelf life and a broader market. Community service activities were conducted through surveys, training, and mentoring on using the dehydrator. The results showed a significant increase in participants' understanding and skills, with 90% becoming familiar with the dehydrator and 100% stating the technology was more efficient than traditional methods. The processed products were more hygienic, higher in quality, and helped reduce lemon waste. Thus, the application of the dehydrator at Andrau Nursery MSME reduces harvest waste, expands product diversification, and strengthens the competitiveness of the local horticulture-based business.

Abstract

Tumbang Nusa Village, Pulang Pisau Regency, Central Kalimantan, has natural resource potential in the form of purun (Lepironia articulata), which grows abundantly in peatlands, swamps, and along riverbanks. Purun has long been utilized by the local community as raw material for handicrafts such as mats, bags, wallets, and eco-friendly straws. However, the purun-flattening process, which is still carried out manually, creates several challenges, including lengthy production times, inconsistent fiber quality, and heavy physical burdens on artisans. This community service activity aimed to provide training on the use of purun-flattening technology for the "Nusa Sehati" Joint Business Group to improve efficiency, quality, and production capacity. The implementation method included a pre-test, socialization, training, practical tool use, and a post-test to measure the activity's effectiveness. A total of 20 participants were involved, the majority of whom were women of productive age. The results indicated significant improvements in ease of use, time efficiency, product quality, and fatigue reduction. In the pre-test, only 40% of participants found manual flattening easy; after using the tool, this increased to 95% in the post-test. All participants (100%) stated that the tool saved production time and reduced fatigue, while 90% rated the fiber quality as very good. Regarding acceptance, 85% of participants stated they would definitely continue using the tool. Thus, training in the application of purun-flattening technology proved effective in enhancing artisans' skills, productivity, and competitiveness. This activity also contributes to strengthening the local economy by leveraging regional potential in a sustainable, environmentally friendly manner.
