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

The demand for fuel oil is increasing day by day, resulting in the depletion of oil and gas reserves in Indonesia. Rice husk waste biomass and low-density polyethylene plastic are wastes that can be utilized as alternative fuel sources by pyrolysis method. Pyrolysis is the process of burning organic and synthetic materials in conditions of little or no oxygen by utilizing heat from high temperature combustion. Pyrolysis method processing requires a heater to burn the material during the process. Efforts that can be made are the use of biomass stoves as the right solution because of the availability of abundant and cheap raw materials, biomass stoves can also provide solutions to reduce the impact of environmental pollution smoke. The purpose of this study was to determine the temperature produced by the biomass stove and the effect of the comparison of the composition of the biomass mixture of rice husk waste and low density polyethylene plastic waste on the quantity of pyrolysis oil. This research uses experimental method with quantitative descriptive analysis technique. This research was conducted by pyrolyzing a mixture of rice husk biomass waste and low density polyethylene plastic waste with variations in composition ratio of 0%:100%, 25%:75%, 50%:50%, 75%:25%, and 100%:0%. The pyrolyzed oil was then filtered and tested for quantity. The test results show that the biomass stove can be used as a heater in a pyrolysis device with a capacity of 4 kg of coconut shell briquettes. The use of coconut shell briquettes as fuel has the advantage of being able to produce higher heat and last longer than charcoal. The biomass stove can produce the highest pyrolysis temperature reaching 665.5°C at the bottom, 541°C in the middle, and 430.3°C at the top. There is an effect of variation in the composition of the mixture of rice husk waste and low-density polyethylene plastic waste on the quantity of pyrolysis oil. The composition of more rice husk waste compared to low density polyethylene plastic waste produces less quantity of pyrolysis oil, while the comparison of the composition of more low density polyethylene plastic waste compared to rice husk waste produces pyrolysis oil with more quantity. This can be seen from the quantity of pyrolysis oil produced ranging from 265 ml to 853.3 ml.

Abstract

The main purpose of this study was to determine the effect of variations in gamma ray dose on the physical and mechanical properties of natural fiber reinforced polymer blend composites. The method used in this research is experimental. This research was conducted on polymer blend composites, namely recycled High Density Polyethylene (rHDPE) and recycled Polypropylene (rPP) with bamboo fiber reinforcement with variations in gamma ray doses of 0 kGy, 25 kGy, 50 kGy, and 75 kGy. Bamboo is processed using a crusher into fibers with a size of 40 mesh and treated with 5% NaOH alkali for 10 minutes then dried using oven for 24 hour at a temperature of 105 °C to remove lignin contained in bamboo fibers. The composite was made using two machines, namely an extrusion machine with a heater temperature of 175 °C, 180 ºC, 185 ºC, and 190 ºC with a screw speed of 25 rpm. Then the injection molding machine with a temperature of 220 ºC with a specimen mold temperature of 90 ºC and an injection pressure of about 45 bar for 20 minutes. Gamma ray treatment was carried out after making the specimen before testing. Where a gamma cell irradiator is used and as a source of gamma rays, cobalt-60 (Co-60) is used. Tensile and water absorption tests are used to determine the physical and mechanical properties of the composite material according to ASTM D638 type V and ASTM D570-98 standards. The test results showed that the higher the dose used, the lower the physical and mechanical properties of the composite. The highest tensile strength was found at the 25 kGy dose treatment of 13.68 MPa and the lowest at the 75 kGy dose treatment. The lowest water content absorption and thickness expansion after 144 hours of immersion were at a 50 kGy gamma dose of 3.43% and 1.27%, respectively. Meanwhile, the highest condition was found at the 75 kGy gamma ray dose of 3.79% and 1.42%, respectively.

Abstract

The need for energy progressively increase, meanwhile fossil fuel reserves gradually decrease since it is nonrenewable resourses. Coffee grounds and polypropylene plastic waste can be used as alternative fuels. One of the ways to use coffee grounds and plastic waste as fuel is through the pyrolysis process. Pyrolysis is a chemical decomposition process of a material thermally in the absence of oxygen which converts RDF-4 into a liquid smoke product in the form of oil. The purpose of this study was to determine the effect of the comparison of the composition of the mixture of coffee grounds and polypropylene plastic waste on the quantity of pyrolysis oil. This study uses an experimental method with quantitative descriptive analysis techniques. This research was carried out by means of a pyrolysis process on RDF-4 a mixture of coffee grounds biomass waste and polypropylene plastic waste with various composition ratios of 0%:100%, 25%:75%, 50%:50%, 75%:25%, and 100%:0%. The pyrolysis oil is then filtered, for later testing the quantity. The test shows that there is an effect of variations in the ratio of the composition of the biomass mixture to the quantity of pyrolysis oil. RDF-4 from coffee grounds waste mixed with polypropyelene plastic waste produces a quantity that tends to decrease as the ratio of coffee grounds composition decreases. RDF-4 which is not mixed with coffee grounds or has a composition ratio of coffee grounds less than the composition ratio of polypropylene plastic waste produces pyrolysis oil with more quantity and quality that tends to be better than the ratio of other RDF-4 compositions. The quantity of pyrolysis oil produced ranged from 219.33 ml to. 1026.67 ml. RDF-4 from 100% polypropylene plastic waste produces pyrolysis oil with the highest quantity of 1026.67 ml with the highest pyrolysis temperature achieved 391°C at T1, 345.5 °C at T2, and 367.75 °C at T3.
