Abstract

One of the parameters that affect turbine performance is the amount and shape of the turbine blades. This study aims to determine the effect of the amount of Archimedes screw turbine blades on turbine performance. The type of turbine used in this study is the Archimedes turbine with single and double screw balde. The turbine test was carried out in the Puri Kedaton river, Pematang Gajah village, with a flow rate entering the turbine of 0.043 m3/s. The shaft load received by the turbine is varied, namely 30 kg, 40 kg, 50 kg and the tilt of the turbine is installed 30°. The test results show that the double screw turbine type produces 518 Watt turbine power with the highest efficiency of 80,5%.

Abstract

 Indonesia is an archipelagic country and is a developing country and not all of its territory has easy roads to traverse, and some parts of its territory are still swamps. Hovercraft are one solution to reach areas that are difficult to pass by this type of vehicle. In this research, before carrying out the hovercraft fabrication process, design testing was carried out in this research. Design testing was carried out using the Finite Element Method (FEM). This test aims to determine whether the hovercraft design that will be fabricated will have sufficient strength in terms of construction. On the construction side, it is hoped that the hovercraft will have a long life cycle (fatigue testing) and good material strength. Design testing was carried out with a load of 250 kg (passenger); 500 kg (machine) and type I or H aluminum construction for better force and stress propagation. The results of this research include that the hovercraft construction design is suitable for use with a 250 kg passenger load and engine load. This is shown in the discussion which includes details from von Mises stress which is lower than the yield strength of aluminum, total deformation, to damage and life cycle fatigue.

Abstract

The purpose of the study was to; (1) analyze the quality control assessment of the results of the Prakerin students' products at TEFA vocational high school, (2) analyze efforts to improve the entrepreneurial spirit of Prakerin students at TEFA vocational high school, (3) analyze how to improve the activeness of Prakerin students at teaching factory SMK and (4) provide suggestions and input to quality control so that the quality of Prakerin students' products at teaching factory SMK is in accordance with consumer orders. Qualitative research method with a case study approach, Data collection using semi-structured interviews with respondents Principal, quality control staff, teaching factory managers, teachers and Prakerin students at the teaching factory, with the aim of obtaining appropriate and accurate data. Research results; (1) the quality of te products of teaching factory internship students must be in accordance with standards, so strategies are needed; (a) preparation of student competencies, (b). planning, implementation of learning, production activities, and industrial cooperation, (c) students are required to be honest, disciplined, responsible and active, and (d) determining standard operating procedures. (2) students' entrepreneurial spirit is influential during internship at teaching factory. Entrepreneurial spirit includes the ability to think creatively, innovatively, dare to take risks, and take advantage of business opportunities. Internship at teaching factory is a place to produce young entrepreneurs, create jobs and produce graduates with technical skills. (3) efforts to improve the activeness of Internship students (4) suggestions and input from quality control.
