Abstract

The pre-composting process of inked waste paper serves to reduce Pb levels in compost raw materials in the form of inked waste paper by using Pb (lead) degradation agents in the form of corn cob charcoal, activated charcoal, PGPR and cow rumen liquor. This study intends to ensure the quality of waste compost materials in the form of inked waste paper after being given pb degradation agents. Pb test using AAS (Atomic Absorbtion Spectrophotometer) method and cellulolytic bacteria test using pour plate method. The data were statistically tested with Anova and LSD advanced tests. From the results of observations, it was known that the provision of Pb degradations agents in the form of activated charcoal and PGPR has a significant effect on Pb levels and has met SNI 19-7030-2004. Meanwhile, the highest number of cellulolytic bacteria was found in the treatment of giving cow rumen liquor followed by PGPR treatment

Abstract

Traditional food is one of the cultural products that was created to meet primary human needs by involving local wisdom. Various types of traditional food are processed from plants taken from the surrounding environment and other places. Local communities have specific interactions and perceptions of plants as ingredients for their traditional foods. The goal was to determine the diversity, the categories of utilization, the organs used, the preparation methods, and the Cultural Significance Index (ICS) of plants in traditional Tuban food ingredients. This research was conducted by surveying 117 respondents from 20 sub-districts in Tuban Regency, followed by in-depth interviews with 20 traditional food makers in Tuban. The data obtained is in the form of qualitative data in the form of local knowledge of the Tuban people regarding plants in their traditional food ingredients, while quantitative data is in the form of the Cultural Significance Index (ICS). The results showed that there were 15 families consisting of 10 species of plants in traditional Tuban food, all of which were cultivated plants, the most used category of plants as spices and the organs most used were seeds and the highest ICS value was Oryza sativa L.
