Abstract

Banana peel is a waste that many found in traditional markets in Indonesia. People throw it away because they feel the banana skin is no longer have benefits. Whereas the potential electricity can be generated from this banana skin waste by fermenting banana peel with tape yeast. To prove the existence of electricity that can be produced from banana peel waste, it is necessary to do this research. The method is to ferment banana peel without using yeast tape, then do the addition of tape yeast with a certain amount, then seen the effect of adding yeast tape variation to the PH value and the resulting electrical performance (voltage and duration) of electrical energy generated. The results of the research with fermentation method between banana peel with tape yeast, the addition of tape yeast cause the lower the value of PH produced, the higher the voltage and the longer time the lamp lights up during the research.

Abstract

A boiler is a device that serves to heat water to become high pressure and high temperature steam, using heat from the combustion of fuel in the combustion chamber. The growth of the domestic boiler industry will develop with research on boiler technology. One of the parameters of the steam produced is temperature and pressure. It is necessary to have the right water level in the steam production process to get saturated steam which is in accordance with the theory, which is in the range of 150-374ËšC. The results of the research show that the optimal water level is the 4th condition (60%) because it can produce saturated steam according to the pressure target with a constant state in a continuous process using diesel and gas fuel.

Abstract

Boilers are used to lower the temperature of the gas and diesel passed through the tubes, and to separate the fluid between the gas phase (water vapor) and the liquid phase (water). In the Boiler water feedback system, a controller is needed that is able to maintain the stability of the water level. The boiler used often has problems that cause less than optimal steam results. The problem that occurs is usually at the level of the water level with the fuel which causes the combustion results to be not optimal and has an impact on the steam produced to be not optimal. Therefore, this research will focus on determining the most appropriate water level with natural gas and diesel fuel so that maximum combustion results are obtained. The tube will also be installed vertically with a slope of 65ËšC with the aim of increasing heat transfer to the boiler and accelerating the evaporation of water molecules which are expected to produce more optimal steam. The parameters observed were temperature, pressure, and the temperature of the combustion flame, the aim was to determine the effect of air on fuel gas and diesel on the speed of temperature and pressure increase. The results of the research show that the optimal water level is the 5th condition (70%) because it can produce saturated steam according to the Efficiency target with a constant state in a continuous process using diesel and gas fuel.

Abstract

Surfactants are generally produced from petroleum and natural gas derivatives while petroleum reserves are depleting and cannot be renewed. This has the potential to cause an energy crisis on a global scale in the future. To solve this problem, alternative renewable raw materials are needed that can help make surfactants that are environmentally friendly, namely raw materials sourced from vegetable oil. One of the anionic surfactants that can be made from plant materials and is renewable is Methyl ester sulfonate. The purpose of this study was to determine the effect of the mole ratio, temperature and percent of the catalyst and the duration of the sulfonation reaction using NaHSO3 reactants on the resulting MES. The production process of the MES surfactant is carried out by reacting the methyl ester with the sulfonation reagent in the form of NaHSO3 and CaO catalyst in the sulfonation reactor. The results showed that MES had the best characteristics with an optimum state in the ratio of 1: 1.5 mole ratio with 1% CaO catalyst and a temperature of

Abstract

Boiler is one of energy conversion machines. The boiler function is converting water into steam by utilizing the heat from the chemical reaction between fuel and oxygen in the air which is commonly known as the combustion reaction. The research purposes are to determine the effect of the LPG fuel air ratio on the flame temperature and thermal efficiency of cross section water tube boiler, and to determine the optimum fuel air ratio which produces the highest flame temperature and thermal efficiency. The air fuel ratio that use in this research are 29.16; 29.44; 29.71; 29.99; and 30,26. Based on the research, it is known that the fuel air ratio affects both of flame temperature and thermal efficiency of the cross section water tube boiler. On the range of air fuel ration 29.16 to 30.26, it is known that the greater the fuel air ratio, the higher the flame temperature and thermal efficiency The optimum air fuel ratio in this research is 29.99 which produces 680oC flame temperature and 58.85% on steady state saturated steam production, 7010C flame temperature and 59.71% thermal efficiency on non steady state saturated steam production, and 7040C flame temperature and 59.32% on superheated steam production.

Abstract

Technological developments are increasingly showing very significant developments in order to simplify a process, one of which is drying using tools such as rotary dryers. The drying process is very important in reducing the moisture content in a material that functions to improve quality or extend shelf life. In this study, the effect of rotation speed and drying time on thermal efficiency will be tested. The results of the study show the influence of rotation speed and moisture content time. the lowest moisture content is at RPM 3 and the time of 120 minutes is 13.07% which has reached the SNI standard of 14%. Time also affects the drying rate, which can be seen at RPMs 1, 2 and 3 there is a decrease in drying rate of .614 kg/h m² to 0.547 kg/h m² at 120 minutes. The efficiency of the thermal rotary dryer is also affected by the rotation speed seen at RPM 3 and 20 minutes time of 69.39% while at RPM 1 and 20 minutes time of 60.92%.

Abstract

Purpose: This study aimed to socialize the method of processing drilled well water into clean water that is suitable for use as boiler feed water, with a focus on the use of Tray Aerator Venturi tools to improve water quality. Methodology: The method applied was socialization and application of the Tray Aerator Venturi tool using 3D visualization, which was carried out directly at PT Utama Karya Techindo. The activity begins with a site survey, followed by discussions with company management to identify problems. Results: The results of this activity showed an increase in the understanding of PT Utama Karya Techindo staff regarding the water treatment process. The use of the Tray Aerator Venturi is effective in reducing the levels of iron (Fe) and manganese (Mn) in well water, which were previously the main causes of corrosion in boiler pipes. Conclusions: Using the Tray Aerator Venturi is effective and economical for processing well water into quality boiler feed water. Apart from improving water quality, this technology also reduces the risk of corrosion in pipes. This activity succeeded in providing understanding and skills to partners to operate and maintain the water treatment systems independently. Limitations: The lack of money available to manufacture Venture Tray Aerator tools to be implemented directly in companies to be more effective in outreach. Contribution: The outreach can be used for PT Utama Karya Techindo's needs in managing boiler feed water in Tanjung Enim. This service can be used for household needs in managing clean water because the equipment is easy to make and affordable.

Abstract

Coal-fired steam power plants (PLTU) remain essential in electricity generation, especially in countries with abundant coal resources. Thermodynamic modeling based on the Rankine cycle is crucial for both educational and design purposes, but commercial software is often costly and less accessible. This study develops a low-cost simulation tool using Microsoft Excel and VBA to model the Rankine cycle in PLTU systems. Users can input operating parameters, calculate thermodynamic properties using IAPWS-IF97 formulations, and evaluate system efficiency through energy balance analysis. The user-friendly interface features real-time efficiency graphs and energy flow diagrams. Validation results show deviations of less than 5% for key parameters, making this tool effective for engineering education, preliminary feasibility studies, and local research in thermal power generation.
