Abstract

Komoditas kopi merupakan salah satu komoditas andalan yang memberikan kontribusi besar bagi pendapatan nasional. Tanaman kopi selain menghasilkan produk utama berupa biji kopi juga menghasilkan limbah berupa batang dan kulit buah kopi yang memiliki potensi bahan untuk pembuatan asap cair untuk pengganti pestisida sintetik dan penggumpal lateks. Pelaksanaan kegiatan edukasi dan pelatihan pemanfaatan limbah tanaman kopi menjadi asap cair sebagai bahan pestisida sebagai bentuk pengabdian kepada masyarakat Desa Karang Tanding menjadi alternatif untuk meningkatkan pemahaman masyarakat tentang produk ekonomis yang berasal dari limbah tanaman kopi. Kegiatan ini disambut oleh 1.146 orang yang mayoritas mata pencahariannya di sektor perkebunan. Pemanfaatan limbah kopi melibatkan masyarakat dan mahasiswa termasuk penyiapan materi dan pengolahan lanjutan dengan protokol COVID-19 yang direkomendasikan. Kegiatan selanjutnya merupakan sosialisasi penggunaan alat yang diikuti ± 20 masyarakat dengan harapan masyarakat dapat mengedukasi masyarakat lain dan mengaplikasikan langsung pada perkebunan desa Karang Tanding seluas ± 400 Ha. Produk asap cair yang dihasilkan dengan pemurnian asap cair dapat menghasilkan peptisida alami yang aman bagi sektor perkebunan.

Abstract

The present study evaluates the catalytic activity of SiO2/Al2O3‒x and SiO2/Al2O3‒x‒NiMo (where x = 5, 10, 25 g of aluminium weight) synthesized using a potassium hydrogen phthalate (KHP) template-assisted route for the hydrocracking of crude palm oil (CPO) into biofuels. Increasing Al weight modified acidity, porosity, and NiMo dispersion, leading to distinct catalytic behavior. The optimal SiO2/Al2O3‒x‒NiMo catalyst (10 g Al) achieved ~94% conversion, dominated by jet fuel-range hydrocarbons (C10-C14) through synergistic hydrodeoxygenation and acid-catalyzed cracking-isomerization pathway. The enhanced performance originates from the balance between acidity and metal dispersion, highlighting that both template selection and Al loading govern the design of efficient SiO2/Al2O3‒NiMo catalysts for biofuel production.

Abstract

This study aims to determine the effect of adding black pepper (Piper nigrum L.) extract on the characteristics of a hydrogel wound dressing made from a mixture of Polyvinyl Alcohol (PVA) and Carboxymethyl Cellulose (CMC), and citric acid as a crosslinking agent. The manufacturing process was carried out by chemical crosslinking with varying concentrations of CMC (5%, 7.5%, 10% w/v) and black pepper extract (0%, 10%, 20%, 30%, 40% v/v). The analysis included FTIR, SEM, swelling degree, water solubility, tensile strength, and antibacterial activity against Staphylococcus aureus. The results showed that the addition of black pepper extract increased antibacterial activity and water absorption (swelling) up to 200–500%, in accordance with the standards for good wound dressings. However, increasing the concentration of black pepper extract tended to decrease water solubility due to its hydrophobic nature. Overall, the PVA/CMC hydrogel with the addition of black pepper extract showed potential as a biocompatible wound dressing with good mechanical properties and antibacterial activity. The gel released 23.12µg/cm²curcumin within 150 minutes.
