Abstract

When designing many variables influence the thermal conversion system for homogeneous biomass and heterogeneous biomass. The factor that can have an important influence is the higher the calorific value (HHV). Many correlation models have been developed to estimate the HHV of homogeneous and heterogeneous biomass to reduce analysis costs. Unfortunately, the correlation model for predicting biomass HHV still has shortcomings when predicting biomass data from different thermal conversion processes and different types of biomass. In this study, four new correlations based on proximate and ultimate analysis of homogeneous biomass with the hydrothermal carbonization (HTC) method used for HHV prediction are presented. The multiple linear regression method is used to produce correlations from homogeneous biomass data then compare biomass models from open literature and compare correlation accuracy for data from the literature. It was found that the correlation obtained from proximate analysis (HHV =967.171 -8.684Ash -9.299VM -9.913FC) was more accurate than that obtained from proximate.

Abstract

This community service program aims to strengthen the role of batik artisans as creative economy actors in preserving Tanjung Pasir batik as a local cultural heritage. The program was conducted in Tanjung Pasir Village by involving batik artisans as the main partners, supported by community leaders, village government, and local MSME actors. The method applied was Participatory Action Research (PAR), which emphasizes active community involvement throughout all stages of the program, including condition and potential mapping, action planning, mentoring implementation, as well as evaluation and reflection. Data were collected through participatory observation, in-depth interviews, and activity documentation. The data were analyzed qualitatively through data reduction, data presentation, and conclusion drawing. Data validity was ensured through source and technique triangulation. The results indicate that the PAR approach enhances awareness and participation of batik artisans in preserving local cultural values reflected in the production process and philosophical meaning of Tanjung Pasir batik. This program is expected to contribute to the strengthening of culture-based creative economy development.
