Citronella oil is one type of essential oil that has been studied for its potential as a fuel bio additive because of its volatility and ability to dissolve into fuel. The purpose of using this bioadditive is to increase engine performance. This research was conducted using an experimental method, some of the samples tested consisted of pertalite fuel, bioethanol then the development was carried out by adding the Bioadditive element citronella oil to the fuel with a ratio of 2,0 : 1000 ml, 3,0 : 1000 ml, and 3,5 : 1000 ml. The sample test was aimed to measure engine performance using a dynamometer. The results of this study show that the use of citronella bioadditives can improve motorcycle performance, the maximum power increases by 55% at a ratio of 2,0 : 1000 ml, and the optimum torque is achieved by 39% at a ratio of 2,0 : 1000 ml. In addition to these tests, measurement of fuel consumption is also carried out by producing a savings of 10%, using a ratio of 2,0 : 1000 ml.","PeriodicalId":102197,"journal":{"name":"JOURNAL OF MECHANICAL ENGINEERING MANUFACTURES MATERIALS AND ENERGY","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125187230","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}

The results of the analysis using the FTIR spectrum showed that the vibration mode correlated with the vibrations of the octahedral units of NiO6 and LiO6 in the wave number zone of 400 - 700 cm−1. Thus, the peak around 433 cm−1 is caused by the Li–O asymmetric strain vibration of LiO6 and the NiO6 bending vibration, namely [(Ni–O–Li)], occurring at 551-603 cm−1. The results of the observation of the microstructure with SEM showed the size of the micron with an uneven and homogeneous surface. The elemental compositions of Li and Ni metals were analyzed by EDXS showing that the metal content of Li and Ni decreased as the calcination temperature increased. The results of the crystal structure test using an X-ray diffractometer showed that with the increase in the calcination temperature, the average diameter of the crystallites decreased, but the average dislocation density increased and the mean micro-lattice strain also increased ( 0.4817% to 15.8079%) and in the Miller hkl index plane.

Failure of these electronic components may result in improper preparation of the fuel mixture. This also affects driving safety. The impact of individual errors can have a negative impact on traffic safety and can also have a negative impact on other participants. The subject of this study was to investigate the impact of failure of electronic components on selected operating characteristics. This article is to determine the failure rate of electronic mechanical components and can affect the operation of road vehicles. Eight electronic system faults are simulated with specific vehicles and use fuel assemblies in gasoline fuel. Measurements were made based on laboratory conditions that gave to change the characteristics of the vehicle handling between damage and corruption. Making the vehicle power parameters and the selected exhaust emission components are determined for the selected vehicle characteristics. The results show that the engine failure of the electronic system has a great impact on the operating characteristics, and at the same time there are situations in the normal operating state of the vehicle in which some of these defects are unknown to the vehicle operator ricefield. The results of the publication can be used in the fields of written law, production and operation of road vehicles, and mathematical modeling of gas emission production from road transportation.","PeriodicalId":102197,"journal":{"name":"JOURNAL OF MECHANICAL ENGINEERING MANUFACTURES MATERIALS AND ENERGY","volume":"31 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116212452","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}

In this study, simulations were carried out with simscale software to analyze the temperature, pressure and gas velocity in the pyrolysis pipe as the length of the pipe increases. The material used is stainless steel AISI 304. This research begins by determining the dimensions and materials of the pyrolysis pipe, the length of the pipe and the input temperature. The length of the pipe was varied by 1.5 m, 1.75 m and 2 m, with initial temperature variations of 450°C and 550°C, respectively. From the simulation result, Increasing of the pipa’s length then the heat transfer will be close to the optimum condition. So that the output temperature, pressure and velocity will be lower. This happens because the length and diameter of the pipe affect the output. From the simulation results, pipe lengths of 1.5 m, 1.75 m, 2 m with input temperatures of 450°C and 550°C obtained the best results for a pipe length of 2 m with an input temperature of 450°C.","PeriodicalId":102197,"journal":{"name":"JOURNAL OF MECHANICAL ENGINEERING MANUFACTURES MATERIALS AND ENERGY","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128298051","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}

This is due to the presence of iron impurities (Fe) forming an intermetallic phase which is dissolved into the Zn-Al alloy which can be seen in its microstructure. So that problems arise that will result in defects in the castings and reduce the mechanical properties of the castings. This study aims to determine the effect of adding Al-5TiB modifier as a grain refiner in changing the morphology of the intermetallic phase of the alloy. This research was conducted at the Department of Metallurgy and Materials, FTUI, Depok and the objects were Zinc-Aluminum Zamak 3 and several other supporting metals. This study uses an experimental method. The results of the investigation show that the effect of impurities through the addition of iron (Fe) 0.04% and 0.19% can lead to an increase in the intermetallic phase fraction at the grain boundaries which causes a decrease in tensile strength, impact, and fluidity in Zinc - Aluminum alloys. The addition of 0.5% and 1% Al-5TiB grain refiner to the Zamak 3 master alloy with 0.19% iron (Fe) content resulted in an increase in the mechanical properties and fluidity values of the alloy. This is due to the formation of an intermetallic phase which is more uniformly distributed over the finer grain boundaries.","PeriodicalId":102197,"journal":{"name":"JOURNAL OF MECHANICAL ENGINEERING MANUFACTURES MATERIALS AND ENERGY","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115255658","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}
