Abstract

Currently, the Indonesian people are faced with various problems in terms of waste management, both organic and inorganic waste. Some of the wastes that can be used are palm waste, coffee grounds and HDPE plastic waste which can be used as alternative fuels, one of which is through the pyrolysis process. Pyrolysis is a process of chemical decomposition of a material thermally in the absence of oxygen. This pyrolysis process converts RDF-5 biomass into a liquid smoke product in the form of bio-oil. This study aims to determine the quantity of pyrolysis oil through the best variation of the composition ratio used. In this study used composition ratio variables, namely 50%:30%:20%, 40%:40%:20%, and 30%:50%:20%. The results of this study obtained the best quantity from a mixture ratio of 50% palm waste, 30% coffee grounds and 20% HDPE plastic to produce 200 ml. The composition ratio affects the quantity of pyrolysis oil results. RDF-5 from palm waste and coffee grounds with HDPE plastic waste binder produces a quantity that tends to decrease as the composition ratio of palm waste waste decreases.

Abstract

In the current era, automatic motorbikes are the most popular motorbikes and are most widely used for everyday purposes. The motorcycle population always increases by around 5 million units every year. Of this amount, around 70% are motorbikes of the matic type, aka scooters. One trick that is usually used by automatic motorbike lovers to upgrade the characteristics of their automatic motorbike is to replace a part called the CVT roller. The aims of this study were: (1) To find out the effect on fuel consumption produced by a 110cc automatic motorcycle using variations in roller weight. (2) Knowing the effect on fuel consumption produced by 110cc automatic motorbikes using variations of engine speed. (3) Knowing the effect of using roller weight variations at RPM variations on fuel consumption on 110cc automatic motorcycles. The research method used is experimental. The research data was obtained by measuring the Honda BeAT New 2018 motorcycle sample. The independent variable is roller weight Variation and Variation of engine rotation. The dependent variable is fuel consumption. The data obtained were then analyzed using quantitative descriptive techniques by describing them in the form of graphs and tables. The results of this study are: (1) The use of variations roller weight 10, 12, and 14 grams have an effect on fuel consumption. The use of a roller that is heavier or lighter than standard (12 grams) has the effect of producing a more different fuel consumption. (2) Variations in engine speed (3500, 5000 and 6500 RPM) have an influence on fuel consumption. Each increase in engine speed, the fuel consumption will also increase. This happens because the higher the engine speed, the higher the amount of fuel burned in the combustion chamber. (3) Has the effect of fuel consumption on the use of roller weight variations and variations of engine speed. This effect lies in the average fuel consumption using less standard rollers when compared to using lighter or heavier rollers. Overall, if you take the best, then the right choice is a standard 12 grams roller, because it has the lowest average fuel consumption value.
