Abstract

Waste biomass is increasingly growingly and will be environmental pollution if not used wisely, this waste can be processed into fuel alternatives, in addition to the smoke from burning waste can be used as liquid smoke, as fertilizers and preservatives, both textile and food. This study aimed to determine the effect of time and temperature of the liquid smoke results from nut shells. Total sampel of research as 1500gr using pyrolysis method. Pyrolysis process is carried out at a temperature pyrolysis reactor 150-450oC. The production of liquid smoke from shell nut 1500gr by the method of pyrolysis produces liquid smoke grade 3 with the results of the best liquid at a temperature of 450oC and the optimum time of 2,5 hours at a yield of 32,66%. From the analysis using GC-MC spectrophotometer produces major chemical component of phenols(36,310%), acid(12,9475%) and carbonyl(16,715%).

Abstract

A thermoelectric generator (TEG) is a device that can convert heat energy into electrical energy through the Seebeck effect. This study aims to analyze the performance of a TEG as a power generator in a portable stove by utilizing the waste heat generated during the combustion process. Tests were conducted with varying temperature differences between the hot and cold sides of the TEG, as well as measuring the output power and energy conversion efficiency. The results show that the performance of a TEG is greatly influenced by the given temperature difference, where increasing the temperature on the hot side and optimal cooling on the cold side can increase the electrical power generated. Although the conversion efficiency is still relatively low, this system has potential as an alternative power source for small devices in off-grid environments. This study is expected to be a reference in the development of thermoelectric technology for portable and renewable energy applications.
