Abstract

Papua Island is at the eastern end of Indonesia, with massive potential of natural resources. However, the human resource growth of this province is low. In 2020, the Human Development Index reached 60.62 and the poverty rate was 27.38 %. The lack of energy at isolated areas is the reason for these facts. So, there is a need of research to utilize the local potential, such as sago waste as bioethanol alternative fuel. This research consist of pre-experimental and experimental process. The pre-experimental purpose is to analyze sago pulp material using Scanning Electron Microscope (SEM), where the Carbon Value (CK) is 76 %, proximate 82.4 % carbohydrate content is very feasible in the process as a bioethanol fuel. The experimental process shows bioethanol sago pulp 70 % is very viable as a fuel, in research applications laminar jet flame bioethanol atmospheric at a fuel mass flow rate of 60 mL min^-1, with a temperature of at least 327 °C up to a maximum temperature of 729 °C. The results of bioethanol diffusion laminar jet flame temperature testing are very feasible to use in household furnace combustion applications in isolated areas in the Papua region.
