Abstract

Argopuro Mountains, Tanah Wulan Village, Maesan District, Bondowoso Regency, East Java, Indonesia is one of the Robusta coffee-producing areas. Robusta coffee beans that are processed can produce quite a lot of by-products in the form of underutilized waste. It is known that coffee skin waste still has a lot of remaining content and it is possible to take these bioactive compounds using extraction methods. Bioactive compounds in natural materials can be done by extraction. Extraction is the process of separating substances in a sample based on different solubilities. The extraction method used is the ultrasonication method (nonconventional). Extraction of the ultrasonication method only requires a relatively shorter time with the help of an ultrasonicator. There is a lot of content in the coffee skin waste powder that needs further testing. The results of this study are expected to provide economic value to robusta coffee husk waste.

Abstract

Tofu is a source of vegetable protein that has high nutritional value for Indonesian Tofu, which is made from soybeans, produces waste from production, one of which is tofu dregs which cannot be stored for long and can pollute the environment. In general, the protein content in tofu dregs is still high, while until now its use is still relatively simple, namely only as animal feed. The content of tofu dregs which is still high in nutrition needs to be optimized for its use as an alternative functional food by processing it into tofu dregs flour, where in 100% tofu dregs flour contains 66.24% carbohydrates, 17.72% protein, 3.23% crude fiber, and 2.62% fat. However, the lack of knowledge about tofu dregs management, knowledge about nutrition and the benefits of tofu dregs, as well as the lack of innovation that can be applied from tofu dregs, causes most of the tofu manufacturing entrepreneurs to still consider the economic value of tofu dregs to be low. The solutions that have been provided include (1) Counseling on the nutritional content that is still present in tofu dregs (2) Socialization on methods that can be applied to process tofu dregs into flour and the benefits of tofu dregs flour. The result of this service activity is that partners get additional knowledge about the management of tofu dregs into high-fiber and low-fat food flour.
