Almost all activities require clean water, both for the metabolism of living things, agriculture and industry and is a major need. So that the availability of clean water sources needs to be maintained and looking for new sources. One source of clean water is atmospheric air which is very abundant. By using a water generator from stable atmospheric air, where the air enters the PAWG system in which there is a thermoelectric which can form a temperature difference in order to convert water into water vapor which then becomes condensate. The PAWG performance tested here is the inlet air velocity with variations of 0.27 m/s, 0.52 m/s and 0.97 m/s. The results show that the inlet air velocity affects the volume of condensate water and the performance of the Psys and COP systems. The higher the air velocity, the greater the volume of condensate water generated and the higher the Psys. But the results are different for COP, where the highest COP occurs at an inlet air speed of 0.52 m/s followed by a speed of 0.27 m/s and the smallest is 0.97 m/s.","PeriodicalId":153724,"journal":{"name":"ARMATUR : Artikel Teknik Mesin & Manufaktur","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133114485","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 design stage was to carry out the construction design process, material selection, and fabrication process. While the performance test stage aims to determine the ability of the machine to carry out the betel nut drying process. The results of the design of the rotary type betel nut dryer machine consist of a heating system and a drive system.

Undamaged test with radiographic method is one of the tests to see the quality of a weld. The test results are radiograph images and evaluated by a radiographer. So this research is designed by optimizing a system to help the work of a radiography expert in identifying discontinuities by utilizing the Matlab Application. On this system uses the method of characteristic extraction and classification of neural networks (AAN). The system uses a characteristic extraction method with geometric invariant moment (GIM) algorithms and a gray level co-occurenece matrix (GLCM) as identification values used in the classification process. The calcification process uses a backpropagation-type multilayer Artificial Neural Network. The types of discontinuities used as data in this system are incompleted of penetration, crack, wormhole, and distributed porosity using a total of 800 datasets of radiograph imagery data.

Savonius turbine is a vertical axis turbine that is currently widely used as an electrical energy generator, this wind turbine is a type of drag type wind turbine that has a simple design that is in the form of a semicircular curved blade side. Therefore, the author is interested in researching the resulting performance including turbine rotational speed, power generated, and wind turbine efficiency against the variation of the blade radius. The method used is experimental, the stages of this research are in the form of literature studies, making savonius turbines, testing savonius turbines with variations in blade radius as well as data retrieval, data processing, and analysis. Based on the data obtained, the rotating speed of the turbine is influenced by variations in the radius of the blade. The larger the blade radius, the smaller the turbine rotational speed. The maximum turbine rotation speed at blade radius 63 is 173 rpm, while at blade radius, 88 is 118 rpm and at blade radius 113 is 115 rpm. So the highest turbine rotating speed at a radius of 63.","PeriodicalId":153724,"journal":{"name":"ARMATUR : Artikel Teknik Mesin & Manufaktur","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122924881","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}
