Abstract

Pineapple (Ananas comosus) is a nutrient-rich tropical plant often processed into various products. At the same time, its peel waste contains valuable compounds such as bromelain enzyme and ascorbic acid, which are beneficial for skin care. Based on observations by students from the KKN MBKM program at the Faculty of Agriculture UNRI, it was found that the society is very interested in programs that discuss the processing of organic waste using simple methods, in line with the potential for utilizing agricultural product waste in Ujung Batu Timur village. This activity involves utilizing pineapple peel waste as a natural additive in the production of liquid soap through a community service program in Ujung Batu Timur, Rokan Hulu, Riau Province. This community service initiative aims to raise awareness among the community about organic waste management and enhance skills in creating economically valuable products. The methods used include socialization and practical training on making liquid soap from pineapple peel extract. The community service activities are carried out in three stages: preparation, implementation, and evaluation held at the Ujung Batu Timur Village Office and involving 23 participants. Post-training survey results show that most participants felt satisfied and benefited from this activity, with a satisfaction level of 80.45%. This program is expected to contribute to the development of micro-enterprises and improve the welfare of the local community.

Abstract

Stabilitas dan sifat antarmuka emulsi pickering berperan penting dalam menentukan efektivitas edible coating untuk mengendalikan susut bobot buah pascapanen. Penelitian ini bertujuan mengembangkan emulsi Pickering berbasis kompleks selulosa nanokristalin–kitosan (CNC–kitosan) dan minyak biji kelor, serta mengevaluasi keterkaitan sifat fisikokimia emulsi terhadap penurunan susut bobot tomat selama penyimpanan. Emulsi diformulasikan dengan variasi rasio minyak:air yaitu 1:1 (NCM1), 1:2 (NCM2), dan 1:3 (NCM3) dan dikarakterisasi berdasarkan potensial zeta, sudut kontak, viskositas, indeks emulsifikasi (EI), dan indeks kriming (CI). Struktur antarmuka dianalisis menggunakan SEM. Emulsi diaplikasikan sebagai edible coating pada tomat, dan susut bobot diamati selama 15 hari. Hasil menunjukkan bahwa perbedaan komposisi emulsi secara signifikan memengaruhi stabilitas dan sifat antarmuka. Emulsi NCM2 menunjukkan performa terbaik dengan sudut kontak tertinggi (105,6°), EI stabil, CI terendah, serta lapisan antarmuka yang lebih rigid, sehingga menghasilkan susut bobot tomat terendah, yaitu sekitar 12,6% pada hari ke-15. Emulsi NCM3 juga stabil akibat viskositas dan repulsi elektrostatik yang tinggi, namun efektivitasnya sedikit lebih rendah dibanding NCM2. Temuan ini menegaskan bahwa rigiditas antarmuka lebih menentukan performa edible coating dibandingkan stabilitas koloid semata dan berpotensi memperpanjang umur simpan tomat.
