Abstract

The corrosion in the steam line pipes at the Geothermal Power Plant is caused by acidic substances present in the steam, especially H2S and CO2, originating from the geothermal reservoir. During operation, this leads to thinning of the pipe walls, affecting the pipe's thickness. The purpose of this research is to calculate the corrosion rate and compare the CO2 and H2S composition in each header using Aspen HYSYS software to determine their influence on the corrosion rate. The research findings indicate that the CO2 and H2S composition in the steam significantly affects the corrosion rate in the steam line pipes. Higher concentrations of CO2 and H2S result in a higher corrosion rate, and the higher the temperature, the corrosion rate will increase.

Abstract

The limited production of natural gas fuel derived from fossil sources, coupled with the increasing consumption demands across various household and industrial sectors, necessitates efforts to conserve fuel usage. One of the approaches that can be taken is to enhance fuel efficiency. This study aims to analyze the influence of environmental temperature on fuel consumption and efficiency. In this research, the data used is the date or duration of the measurement, including peak load time, environmental temperature and fuel consumption. The research findings indicate that higher environmental temperatures have an inverse impact on fuel efficiency while having a linear effect on fuel consumption. For instance, at an environmental temperature of 32.8 degrees Celsius, the efficiency reaches 12.04% with a consumption rate of 0.72 KG/H, whereas at a temperature of 36.8 degrees Celsius, efficiency decreases to 8.47% with a fuel consumption of 0.96 KG/H. These findings suggest that environmental temperature can influence fuel usage efficiency, and the relationship between environmental temperature and fuel consumption is linear. This research has significant implications for optimizing fuel usage in the context of changing thermal environments.

Abstract

Indonesia harbors considerable prospects for bioethanol fuel generation. Underscoring the imperative for establishing optimal fuel concentrations and appropriate burners to facilitate sustainable energy alternatives; this study endeavored to identify the optimal bioethanol concentration sourced from sago waste for application in Honai burners, evaluating the resultant flame output for domestic energy in Papuan custom houses. This analysis adopted an integration of pre-experimental frameworks along with experimental ones. In the early trial stage, concentrations of bioethanol were thoroughly examined concerning low heat value (LHV), specific gravity, viscosity, gas chromatography, and Fourier transform infrared (FTIR) analysis to identify the best fuel characteristics. Following this, the experimental phase assessed flame characteristics, encompassing temperature, fuel mass flow rate, and emissions from combustion gases within the Honai burner. Pre-experimental findings suggest that an 80 % bioethanol concentration is ideal for the Honai burner, displaying a viscosity of 1.03 cP, a density of 0.82 g·L⁻¹, a gas chromatography content of 61.04 %, an LHV of 16.166 MJ/kg, and a heat release rate of 140 kW·m⁻². The experimental phase indicates that a 14-hole burner oriented at a 45° angle yields optimal performance, achieving stable flame temperatures between 480 °C and 750 °C with a fuel flow rate of 60 mL·min⁻¹. Analysis of combustion gases indicates minimal emissions, with carbon monoxide (CO) registering at 0.01 %, carbon dioxide (CO₂) at 0.2 %, and hydrocarbons (HC) at 27 ppm. In summary, this study offers a feasible approach to addressing energy challenges, meeting demand, enhancing accessibility, ensuring availability, and promoting regional energy autonomy for Papuan households in remote locales through the utilization of bioethanol derived from sago dregs in Honai burner cooking devices.

Abstract

This study presents the design and performance evaluation of a closed-system batik fabric drying machine for small-scale industries. The system integrates a spinner for initial dewatering and a hot-air blower with thermostatic control at 60 °C. Experimental tests examined drying time, temperature stability, and fabric quality. Results showed that 2 kg of batik fabric dried in 18 minutes—about 70 % faster than traditional sun drying. The closed-loop air circulation improved thermal uniformity (±1.5 °C deviation) and reduced energy use by 25 %. No color fading or fiber damage occurred, and ultraviolet lamps prevented microbial growth. This design demonstrates that combining mechanical efficiency, thermal control, and ergonomics can enhance energy efficiency and production reliability for micro-scale batik industries.
