Abstract

The present study was conducted to investigate the dynamics of multiple droplets impact under various surface tensions. Here, the ethylene glycol with compositions of  0%, 5%, and 15% were injected through a nozzle into the stainless steel surface as the multiple droplets. The solid surface was heated at the temperatures of 150ºC. The dynamic of multiple droplets have been observed with frame rate of 2000 fps by a high speed camera. A technique of image processing was developed to determine the maximum droplets are spreading ratio. As the result, the surface tension contribute to the maximum spreading ratio significantly. When the droplet surface tension decreases, the maximum spreading ratio increases. The maximum spreading ratio appears when the percentage of the ethylene glycol is 15% at the temperature of 150ºC. From the visual observation, it was shown that a slower emergence of secondary droplets (droplet splashing) was carried out under low surface tension.

Abstract

The use of biogasoline from Bali wine as a fuel additive in gasoline from fossil energy sources gets a lot of severe problems, especially to make biogasoline products as an alternative fuel that is able to stand alone as the main fuel in Indonesia in the future. This article is in the making based on the results of literature studies by conducting an analysis process on various sources of pre-existing articles. This literature study is processed in various ways such as reviewing the results of previous research on the use of Balinese wine as one of the energy-friendly fossil fuel substitutes. From this literature study obtained the advantages of an engine working umjuk, namely the use of biogasoline from Balinese wine to variations in compression ratio the greater the acceleration produced is also increasing which makes the combustion of the table better, and also the use of fuel becomes more efficient. The use of biogasoline fuel additives from Bali wine against exhaust emissions in the form of carbon monoxide (CO) and carbon dioxide (CO₂) gases decreased. Then in terms of raw materials, it is feared that there is competition between the availability of food raw materials (the manufacture of brown sugar and ant sugar). One solution so that ethanol from Balinese wine in pure biogasoline that can be used as fuel is with adsorbed type treatment and immersion time and interaction are very influential on the quality of biogasoline concentration and percentage value increase in biogasoline concentration when in the dehydration process.

Abstract

This study aims to find out the effect of mixing biodiesel and additives with various kinds of mixtures on the exhaust gas opacity of a 4-stroke diesel engine. In this study, two variations of the ratio of the mixture of bio-diesel and additives were used, namely bio-diesel with a mixture ratio of 2.5%: 97.5% and a mixture ratio of 1.25%: 98.75% for additives and bio-diesel. The method used in this study uses an experimental method where the data collection process is carried out through observation and documentation. Data collection was carried out 5 times a repetition using the Opacity Smoke Meter tool. From the results of the study, the variation of the mixture of 2.5%: 97.5% resulted in the lowest average exhaust gas opacity value, where there was a decrease in exhaust gas opacity by 20.8% compared to standard conditions (without the addition of additives). From the results of this study, it can be concluded that there is an impact of adding additives to biodiesel on exhaust gas opacity where the more additives added to biodiesel will further reduce exhaust gas opacity in vehicles with diesel engines.

Abstract

Increasing global warming due to the uncontrolled use of fossil fuels has resulted in climate change which is currently a worldwide concern. Various efforts to use alternative energy have been made to overcome these problems, one of which is Pyrolysis technology to convert solid plastic waste into liquid fuel. Pyrolysis is a heating process, or the working principle is the same as distilling a raw material particle that will change shape from a solid to a gas and then passing through a condenser tube to cool down so that the steam will turn into a liquid. This process generally takes place at temperatures between 500-800°C. The pyrolysis process occurs with the help of heating from LPG gas. From the data obtained, further testing can be carried out on the physical and chemical properties of the pyrolysis oil to determine its characteristics. The physical properties tested included density and viscosity, while the chemical properties tested were the calorific value of the plastic pyrolysis process. The next step is to test the pyrolysis oil using WBT (Water Boiling Test) to determine the performance of the oil stove with pyrolysis oil as fuel. From the results of the efficiency of the stove from the pyrolysis of plastic oil, it is known that the largest input energy (Qin) is obtained in the pyrolysis oil without a catalyst in the first condenser of 2375,291 watts. The result of sensible heat (SH) of the most significant pyrolysis oil sample from pyrolysis without a catalyst in condenser one is 125.4 watts. The highest latent heat value was found in the pyrolysis of natural zeolite catalyst in condenser three at 231.752 watts, while the highest thermal efficiency value of pyrolysis using natural zeolite catalyst in condenser one was 28.39%. Natural zeolite catalysts reduce the liquid and solid products but increase gas products. The catalysts from pyrolysis oil have a darker color than without a catalyst. The cause is the reaction of the catalyst during the pyrolysis process.
