Analysis based on implementation needs to be carried out with the aim of adapting the use of water transportation technology, namely ships with electric power, according to the required competencies. This research was carried out using a descriptive qualitative approach method with a literature study type of research. The research was carried out by collecting data from secondary sources such as books and journal articles related to the variables and subjects of this research. From the research results, a comparison was obtained between the abilities currently possessed by fishermen, and the abilities that fishermen must have in the future in facing developments in water transportation. It is known that, in terms of use, users need to understand the use of electric propulsion ships and K3 in their application, in terms of understanding more about the main components of the technology used, in terms of maintenance being able to repair and maintain the components, and understanding the social impacts that occur as well as the advantages and disadvantages of using them. Therefore, efforts are needed to educate the public so that they can easily receive clear information about electric propulsion ship technology, so that the results of the development of this technology can be accepted by the general public.","PeriodicalId":270564,"journal":{"name":"Accurate: Journal of Mechanical Engineering and Science","volume":"2 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141686443","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 tropical climates cassava is needed for its growth process so that this plant cannot grow at temperatures below 10 c. Cassava is a tuber or tree root that can grow on sandy to clay soil, as well as on low fertility soil. The length of cassava ranges from 15-30 cm with a relatively different diameter, which is 2-5 cm. Cassava has a skin consisting of two layers, the first layer is the outer skin while the second layer is the inner skin with white or yellowish flesh. In its production so far, cassava cutting is still using human power (manual). It would be better if the production of cassava cutting increased without ignoring the existing human aspects. Therefore, a machine is needed as a human tool in increasing the productivity of cassava cutting. Significant results or not, can later be observed from the data obtained before and after using the machine. A significant increase after the experiment was carried out means that the cassava cutting machine was able to help the existing cutting process. This can be seen later by using SPSS calculations.","PeriodicalId":270564,"journal":{"name":"Accurate: Journal of Mechanical Engineering and Science","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126938082","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 study aims to determine the effect of the blade angle of the turbine on the tip speed ratio (TSR) and power coefficient (CP) by using a Q-Blade simulation. Q-Blade software can predict the value of the power generated at the blade rotation by comparing the CP and TSR values. The type of airfoil NACA 4412, taper blade, blade's numbers (4), blade radius (0.3 m), wind speed ± 3.6 m/s were fixed variables in this study. The simulation generated a graph of the relationship between CP and TSR changed and a simulation image of the load distribution ensued in the blade geometry. The blade angle of 30 at the TSR number 5 produced the highest CP values, which was ±0.4. The low loading value in the axis/rotor region, at a variation of the blade angle of 30, balances the centrifugal force on the rotating fluid. The centrifugal force produces thrust on the turbine so that the blade rotates with a high CP value in that area.","PeriodicalId":270564,"journal":{"name":"Accurate: Journal of Mechanical Engineering and Science","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126715864","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}
