Since 2012, the significant reduction of onion production was up to 19%. One of the farmers group facing the reduction is Sumber Makmur III with total of reduction is up to 61.69%. The culture technique has done by farmers using conventional lamp and net which have many weaknesses from its implementation. Based on this problem, innovative technology MOAT (Moth Attractor Technology) has created as portable moth attractor. It is the innovative solution using lamp, box and glue completed by RTC (Real Time Clock) and having special glue to intensify the effectiveness and efficiency in exterminating the moths. Following methods have done are (1) literature study and observation, (2) designing product, (3) production, (4) device trials, (5) product’s socialization and implementation, and also (6) monitoring and evaluation. The result is MOAT which can effectively attract up to 770 months in a week. It can help the farmers reduce the damage of onion and increase the production up to 11.07 quintal in 180 m 2 area. Furthermore, it can also increase the income of onion farmers.","PeriodicalId":16315,"journal":{"name":"Journal of Mechanical Engineering Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47407848","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 mould that is commonly used is sand moulding. Binder which commonly used in sand casting process is bentonite. Bentonite is kind of mineral which can be run out if it is used continuously. The background of this study was to analyse the other binder that could reduce the use of bentonite by utilizing eggshell. This study aimed to analyse the hardness, microstructure, macrostructure, and fluidity of the cast which yielded by using variations of eggshell. The method that used was experimental method with a model of one-shot case study with descriptive analysis. The study result showed that the highest value of fluidity test was found at variation of 7% eggshell and 3% bentonite with hardness value of 180.86 HV. There were found several defects, casting result with variation of 4% eggshell and 3% bentonite found that there were ± 28 pinhole defects and ± 20 open grain defects. There were found ± 65 pinhole defects and ± 30 open grain structure defects in the casting result with variation 7% eggshell and 3% bentonite.

The metal forming process can be executed in 2 ways, namely by hot working and cold working. During these two types of mechanical working process, the metal undergoes plastic deformation. In hot working, the required deformation force is relatively low, and changes in mechanical properties are also insignificant. In cold working, a higher force is required, but the strength of the metal will increase significantly. The use of simulation has become increasingly widespread to predict and describe process mechanisms and optimize the pre-forming process. The study was conducted using a three-dimensional (3D) simulation to predict the effect of variations in time, material and temperature on the damage of pre-forming blocks. The simulation results showed that the greatest damage occurred after 0.006 s and at 25 °C to the specimen 1 (Aluminium 1xxx) with the highest damage value of 0.011833 which occurred.
