The organic acid content in bio-oil gives bio-oil acidic properties. Bio-oil can be obtained in the pyrolysis combustion process, using a combustion tube. The number of tubes used can affect the yield characteristics of bio-oil. The purpose of this study was to determine the characteristics of bio-oil bio-oil produced by varying the number of combustion tubes in the pyrolysis process. Such as pyrolysis time, amount of bio-oil, temperature and content of bio-oil. This research method utilizes cocoa shell biomass waste to turn into bio-oil with a pyrolysis process, namely by varying the number of combustion tubes, namely one tube, two tubes and three tubes with a diameter of one tube 27.74 cm, two tubes 19.6 cm and three tubes 16 cm with the same cylinder volume of 18.7 cm3, by carrying out the prolysis process, namely putting the cocoa shell waste into the combustion tube and closing it. Then the combustion tube is inserted into the pyrolysis reactor and then closed and then burned. From the results of the research, the results of bio-oil in a single tube of raw material were 130 ml with a processing time of 113 minutes and bio-oil characteristics, a calorific value of 2177,464 cal/g, a viscosity of 1,574 CPs, and a pH of 4.77. Whereas in the second raw material tube, there were 80 ml with a processing time of 105 minutes and specifications for bio-oil, a calorific value of 2071,151 cal/g, a viscosity of 1,780 CPs and a pH of 4.96.

Furthermore, this research studies the effect of mould preheating so that the temperature inside the cavity can be maintained, especially for narrow holes. The process starts with making the engine cylinder head pattern and gating system using a three-dimensional printer with polylactic acid resin. The mould pattern and gating system are combined and coated with a layer of cement plaster, silica sand and kaolin. After the coating is dry, the mould is heated until the mould pattern evaporates and there is no residue. The casting process was carried out at pre-heating moulds of 300 0C and 350 0C and a pouring temperature of 800 0C with pouring speeds of 20, 30, and 40 rpm. The final stage of the research is manufacturing test objects and testing mechanical properties. The results showed that the higher the pouring speed, the less perfect the casting results, especially in the cylinder head fins. The best casting results occurred in the pre-heat condition of the 300 0C mould with a pouring speed of 20 rpm, with a Maximum Tensile Strength of 105 N/mm2, Hardness 53 hardness Brinell test (HBN), Density and Porosity of 2.43 gr/cm3.

In the transportation and industrial sectors, the use of fossil energy is the main energy source. This is because the fuel used in transportation and industry still relies on fossil fuels. To overcome the energy crisis in the future due to the exploitation of fossil energy, it is necessary to use alternative energy. One alternative energy that can be used is biodiesel. Biodiesel can be obtained from animal or vegetable fats. Kesambi is a plant that has the potential as a biodiesel feedstock. The kesambi plant can produce oil obtained from the seeds of the kesambi fruit through the pressing process. However, before being used and mass produced, a product testing process is required first. Tests can be carried out using the premix combustion method by varying the equivalent ratio and fuel composition. The fuel used is kesambi biodiesel with the addition of methanol. Testing produces fire characteristics. Flame characteristics yielded data on the relationship between laminer combustion rate and equivalent ratio as well as flame height and fuel composition. The test results show that the highest laminer combustion rate lies in the equivalent ratio 1 of 68,024 cm/s with a fuel composition of B90M10. Then the highest flame height at the equivalent ratio of 1.2 is 25,663 mm with a fuel composition of B100M0.","PeriodicalId":31503,"journal":{"name":"Turbo Jurnal Program Studi Teknik Mesin","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74921143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
