Abstract

Penelitian ini bertujuan untuk mengetahui desain model inkuiri pada mata pelajaran kopling dan komponen-komponennya, serta membuktikan adanya peningkatan prestasi belajar dalam hal memperbaiki kopling setelah diterapkan model pembelajaran inkuiri pada materi kopling. Bentuk penelitian ini adalah Penelitian Tindakan kelas (PTK). Penelitian ini dilaksanakan dalam dua siklus, dengan tahapan setiap siklusnya meliputi kegiatan perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Dari hasil penelitian ini dapat diketahui persentase ketuntasan klasikal dari pre-test, siklus I, dan siklus II. Pada kegiatan pre-test, siswa yang tuntas hanya 17 siswa atau 53,125%. Selanjutnya pada siklus I, siswa yang termasuk dalam kategori tuntas meningkat menjadi 23 siswa atau 71,875%. Hal ini berarti mengalami peningkatan sebesar 18,75% dari pre-test. Kemudian pada siklus II meningkat kembali menjadi 84,375% atau 27 siswa tuntas KKM. Berarti dari siklus I ke siklus II mengalami peningkatan  sebesar 12,5%. Dari penjelasan di atas bahwa penerapan model pembelajaran inkuiri efektif untuk meningkatkan keterampilan memperbaiki kopling dan komponen-komponennya.Issues raised in this study were design an inquiry learning model on the skills of repairing clutch components, how does student achievement after implementation of inquiry learning model. This study aims to determine the design of the model of inquiry on clutch and its components subjects, as well as proving an increase learning achievement in terms of improving the clutch after the inquiry learning model applied to the clutch material. This study is a form of classroom action research (CAR). This study was conducted in two cycles, with each cycle includes the stages of planning, action, observation, and reflection. From the results of this study can be seen the classical completeness percentage of pre cycle, the first cycle and second cycle . Pre-cycle on learning activities, students who completed only 17 students or 53,125%. Furthermore, in the first cycle, students are included in the completed category increase to 23 students or 71.875%. This represented an increase of 18.75 % from pre-cycle. Then on the second cycle increased to 84.375% or 27 students completed the KKM. It means that from the first cycle to the second cycle increased by 12.5%. From the above that the implmentation of inquiry learning model to improve the skills of repairing the clutch and its components. Keywords : Inquiry, Clutch, Learning Outcomes

Abstract

The more rapid development of the times in the era of globalization and technology, the use of transportation is the best solution to support increased human mobility. It is noted that the use of land transportation has increased along with the increase in human mobility. This matter was also followed by the existence of global issues regarding the energy crisis that hit the world. The need for transportation is increasing, resulting in an increase in the energy required.This final project report entitled "Theoretical Aerodynamic Analysis and Application of Inventor and CFD Applications in the Design and Build of the Electric Car Prototype "Inkas A6" Bldc 1000 Watt With the Golf Shuttle Concept" initial design and knowing airflow in the Shuttle golf vehicle simulation process carried out on the Autodesk CFD 2019 application The results of the simulations carried out with the Autodesk CFD 2019 software and the Cd (Coefficient Drag) calculations carried out by researchers on the body of this golf shuttle vehicle obtained a value of 34.3 and the maximum and minimum pressures obtained were 102683 Pa and 1013160 Pa. And for the value of the Drag Force calculation is 2367 Pa then the maximum and minimum relative airspeed obtained is 3.52 m/s and -1.06 m/s.

Abstract

Wind energy can be utilized in wind power plants. Wind power generation is a method for generating electrical energy by rotating a wind turbine which is connected to a generator as an electricity generator, then the electrical energy produced by the generator is stored in an electrical energy storage element (battery). The most important part of a Wind Power Plant is in Wind Turbines or commonly called Propellers. The design and manufacture of this propeller uses dried palm oil fiber as a substitute for glass fiber to reduce environmental pollution and utilize waste from palm oil processing. The propellers in this wind power plant (PLTB) are designed in this thesis with the aim of capturing wind which will be converted into electricity. The design of these propellers is taken into account in various aspects, especially in the aspect of the cross-sectional area which has a width of 25 cm and a height of 25 cm. 50 cm. This size produces 68.0945 watts of power at a wind speed of 6.1 m/s.
