Abstract

Banyuwangi is the largest coffee plantation centre in East Java, with robusta and arabica coffee production reaching 10,518 tonnes per year. Coffee plantation waste, which is abundant, is known as coffee pulp. Coffee pulps can be converted into organic compost/fertilizer, animal feed, and eco-friendly products such as cellulose-based nata/membrane. The abundant availability of coffee pulp waste in Banyuwangi Regency has not been correctly handled or processed to prevent environmental impact. Converting coffee pulp waste into eco-friendly products will benefit the surrounding community and increase the added value of the waste. To overcome these problems, it is necessary to engage in activities involving the local community, local government, and agro-tourism actors through counseling and training on processing coffee pulp waste/bioconversion into eco-friendly products, thereby benefiting the community in Banyuwangi Regency, especially in the Glenmore area. Training participants were given a questionnaire for assessment. Based on the results of the questionnaire analysis, it is known that the participants' understanding before the activity is: 40% of participants were very poorly understood, 13% were poorly understood, 20% were quite understood, 13% understood, and 13% were very familiar with the material of processing coffee pulp waste. After receiving training, 27% of participants achieved an excellent understanding, 33% had a moderate understanding, and 33% had a somewhat understanding. Additionally, there were still participants who did not understand as much as 7%. Based on the participants' assessment, 67% felt that the benefits of this activity were excellent and should be carried out on an ongoing basis.

Abstract

Coffee production in Indonesia continues to increase each year, necessitating sustainable waste management to reduce the accumulation of coffee husk waste in the environment. This waste still contains natural carbon sources that can potentially be utilized as a fermentation medium for bacterial cellulose (BC) production, which is promising for vegan leather applications. This study aims to determine the most effective combination of molasses and ammonium sulfate (ZA) to enhance BC production and optimize the BC pretreatment process for vegan leather application. In this study, chemical composition analysis was also carried out using Fourier transform infrared (FTIR) spectroscopy analysis on samples of coffee fruit peel following the thermal delignification process to determine the optimal conditions for the process. BC production was carried out over 14 days with treatment variations of 5%, 10%, and 15% molasses and 0.3%, 0.5%, and 1% ZA. The pretreatment involved pressing and coating with a coconut oil–beeswax mixture, followed by characterization of BC through physicochemical properties, weight, and thickness. The effect of varying concentrations of molasses and ZA in the coffee husk extract medium had an effect on the weight and thickness of the cellulose membrane produced, with optimal results in treatment P3 (10% molasses and 0.3% ZA) (weight 509 g; thickness 9.69 mm). The pH value was measured before and after fermentation and showed a decrease caused by the activity of acetic acid bacteria.
