Abstract

The escalation of crude oil exploitation poses significant risks of leakage and oil spills in the oceans. Therefore, this research aims to synthesize superhydrophobic sponges utilizing lignin derived from Oil Palm Empty Fruit Bunch (OPEFB) waste. Lignin was isolated from OPEFB with the addition of 15% NaOH, followed by neutralization and purification using H₂SO₄, which yielded a recovery of 30.3%. Subsequently, melamine sponges were modified via a facile dip-coating technique using a mixture of lignin, Polydimethylsiloxane (PDMS), and (3-aminopropyl)triethoxysilane (APTES). The physicochemical properties and material performance were characterized using 1H-NMR, FTIR, and Water Contact Angle (WCA) measurements. 1H-NMR analysis confirmed the successful isolation of the lignin structure, while FTIR spectra verified the effective deposition of the silane-lignin layer on the sponge skeleton. Contact angle analysis results indicated a significant surface transformation, where the sponge shifted from a superhydrophilic nature 0° to a highly superhydrophobic state (170.91°). With such performance, this material holds great potential as an effective, eco-friendly adsorbent for oil spill remediation in aquatic environments.

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.
