Abstract

This study aims to evaluate the effect of varying yeast concentrations on the sensory quality of cassava tapai (Manihot esculenta) and black glutinous rice tapai (Oryza sativa var. glutinosa). The yeast concentrations used were 0.25%, 0.5%, 0.75%, 1%, and 1.5% based on the substrate weight. The parameters observed included taste, texture, aroma, and color, which were assessed organoleptically on the first and second days of fermentation. The results showed that yeast concentrations of 0.5% to 0.75% produced the best quality tapai in both cassava and black glutinous rice, characterized by a balanced sweet-sour taste, soft texture, and the distinctive aroma of tapai. At low yeast concentration (0.25%), fermentation was not optimal, while at higher concentrations (≥1%), over-fermentation occurred, marked by a bitter taste, excessively soft texture, and unpleasant odor. This study highlights the importance of using the appropriate yeast concentration in the tapai fermentation process to achieve optimal sensory quality.

Abstract

Final Disposal Sites (landfills) serve as the endpoint in the municipal solid waste management system, functioning as the final destination for our daily waste. Currently, Indonesia is experiencing a waste crisis due to the continuously increasing volume of waste generation, which leads to the rapid overfilling of landfill sites. One of the potential solutions for utilizing landfill waste is the production of Refuse-Derived Fuel (RDF), an alternative fuel derived from solid waste. However, waste that has been buried in landfills generally contains high moisture content, rendering it unsuitable for immediate RDF application. The calorific value of RDF depends greatly on its moisture content, with higher moisture levels resulting in lower energy output. Therefore, a pre-treatment process in the form of drying is necessary to reduce moisture content and optimize the fuel quality of RDF. This study applies the Solar Greenhouse Biodrying (SGB) method as a waste drying technology that combines heat from solar radiation with biological heat generated during aerobic degradation. This method was selected due to its suitability to Indonesia’s tropical climate and its potential for large-scale application without requiring high external energy input. The waste material used in this study was obtained from landfill waste excavated at a depth of 3 meters, with an estimated age of approximately 9 years. In this study, a mixture of fresh waste and excavated landfill waste was dried using various composition ratios: 1:0 (control), 1:1, 1:2, 1:3, and 1:4. The results show that the SGB method effectively reduced moisture content by 27–62.2% and increased the calorific value to a range of 7.5–14 MJ/kg. The waste composition ratio significantly influenced moisture reduction, with the most optimal result found at a 1:2 ratio, which provided the best balance between drying efficiency and energy enhancement. These findings indicate that the SGB method is an effective alternative for waste drying prior to further utilization as RDF.
