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.

Abstract

To improve the productivity of palm oil mills, maximizing oil recovery and minimizing losses are crucial efforts. One applicable approach is optimizing the mixing of the light phase discharged from the decanter with crude oil from the crude oil tank in the continuous settling tank. This study aimed to analyze the effect of the light phase on the final quality of the produced oil and to determine the optimal mixing ratio that yields the best oil quality. Experiments were conducted with four mixing variations between crude oil and light phase: 90%:10%, 80%:20%, 70%:30%, and 60%:40%. After mixing, laboratory analyses were performed to determine the oil content, free fatty acid (FFA) level, moisture content, and impurities of the resulting oil. The results showed that higher proportions of light phase in the mixture led to increased oil content. The FFA level initially decreased to a minimum at 23.8% light phase due to the dilution effect of crude oil by the light phase, which had higher oil content, but then increased at higher proportions because of the higher FFA contribution from the light phase and potential hydrolysis reactions. Moisture and impurity levels from the light phase did not significantly affect the quality of the mixed oil because their differences compared to crude oil were relatively small. The optimal composition was achieved at 23.8% light phase, yielding 65.07% oil content, 2.0367% FFA, 0.367% moisture, and 0.0189% impurities. These findings indicate that an appropriate mixing strategy can improve oil utilization efficiency and reduce losses, thus supporting productivity enhancement and the sustainability of the palm oil industry without compromising CPO quality standards.
