Abstract

Desa Batur Tengah adalah salah satu daerah penghasil kopi Arabika terbesar di Kecamatan Kintamani, Kabupaten Bangli. Limbah kulit kopi Arabika di Desa Batur Tengah saat ini masih belum dimanfaatkan secara optimal, hanya digunakan sebagai bahan tambahan pupuk, sedangkan sisanya hanya dibuang begitu saja. Oleh karena itu, tujuan kegiatan ini adalah untuk meningkatkan pengetahuan dan ketrampilan Kelompok Tani Harapan Maju melalui edukasi dan pelatihan mengolah limbah kulit kopi Arabika menjadi Cascara sebagai minuman kesehatan, sehingga bernilai ekonomis. Metode pelaksanaan kegiatan ini dengan menggunakan penyuluhan, demonstrasi, pelatihan produksi Cascara, strategi pemasaran produk, dan manajemen bidang hukum, hingga pendampingan. Tim pelaksana pengabdian juga melakukan upgrading teknologi dengan memberikan bantuan berupa mesin dehydrator. Mitra dalam kegiatan ini adalah Kelompok Tani Harapan Maju sebanyak 13 orang, dan untuk mengetahui keberhasilan program dilakukan pre-test dan post-test lalu dianalisis secara deskriptif kuantitatif. Hasil kegiatan menunjukkan bahwa terjadinya peningkatan pengetahuan mitra dalam pengolahan limbah kulit kopi Arabika dari tidak mengetahui menjadi sebesar 92,31% mengetahui. Mitra dapat menggunakan media pemasaran online, dan hukum tentang izin usaha.

Abstract

Biocomposite foam offers an environmentally friendly solution to replace synthetic polymer-based packaging that is difficult to degrade. This study aimed to investigate the effect of taro leaf powder (Colocasia esculenta (L.) Schott) concentration on the characteristics of tapioca-and chitosan-based biocomposite foam, as well as to determine the optimal concentration for producing the best-performing foam. The research employed a Randomized Block Design (RBD) with five levels of taro leaf powder concentration: 1%, 1.5%, 2%, 2.5% and 3%, tested across four blocks based on biocomposite foam production time. The observed variables included tensile strength, tear strength, density, elongation at break, compression set, thickness, swelling, and biodegradation. Data were analyzed using ANOVA followed by the Least Significant Difference (LSD) test. The results showed that variations in taro leaf powder concentration produced the best foam properties, with a tensile strength of 2.04 N/cm2, tear strength of 1.46 N/cm2, density of 0.22 g/mL, elongation at break of 2.77%, compression set of 17.28%, thickness of 12.78 mm, swelling of 0.84%, and a biodegradation time of 15.75 days.

Abstract

Salak pondoh is one type of salak that is very popular because it has a sweet and crunchy taste even though it is picked before it enters its harvest age. The increasing public awareness of the importance of consuming healthy food amidst the lack of time constraints in serving encourages opportunities for peeled salak processing. In the peeled state, salak will deteriorate faster due to the loss of the skin layer. One of the efforts that can be done to inhibit the process is the application of edible coating. This study aims to determine the effect of taro-carrageenan starch combination and glycerol addition on the characteristics of salak pondoh fruit and to determine the right combination of taro-carrageenan starch and glycerol addition on the characteristics of salak pondoh fruit during storage. This study used a factorial Randomized Group Design (RAK) with two treatment factors. The first factor is the combination of taro starch-carrageenan consisting of 3 levels namely P1 (25:75), P2 (50:50), P3 (75:25), and the second factor is the addition of glycerol consisting of 3 levels namely G1 (1g), G2 (2g), and G3 (3g). Each treatment was repeated 2 times with a storage period of 9 days. The parameters observed in this study were weight loss, total soluble solids, vitamin C, total acid and organoleptic. The results showed that the combination of taro starch-carrageenan and glycerol addition had no significant effect on weight loss, total soluble solids, vitamin C, and total acid of salak pondoh during 9 days of storage. Based on the organoleptic test, the variation of taro starch-carrageenan 50:50 and the addition of 1g glycerol is the treatment that gives the best coating results for 6 days of storage with a taste value of 3.20, color 3.73, aroma 3.47 and hedonic value 5.13.
