Abstract

Washing is an activity that is done every day by housewives, young people, and is done by anyone, so it takes time to do washing activities, especially housewives who have so many jobs at home that washing is quite a heavy job for housewives. ladder. The design of the application of the CVT Vario 110 on a mechanical driving washing machine with a maximum capacity of 7 kg is expected to be a solution to the problems of housewives in washing. The method used in this research is by design, Design Analysis and continued with the fabrication process of the design results, and testing the washing machine that has been made. The results of the calculation of washing and drying rotations at the front sprocket are 91.6 rpm, the rear sprocket is 436.3 rpm, and the tube rotation is 127.1 rpm. Then tested using a tachometer with the results of testing the front sprocket 86.3 rpm, rear sprocket 294.6 rpm, primary pulley (CVT) 294.6 rpm, secondary pulley (CVT) 145.5 rpm, and tube (tube) 127, 1 rpm. Based on the test results, this washing machine is capable of washing up to a capacity of 7 kg so it is suitable for use in helping housewives wash their jobs.

Abstract

Heat treatment of ST37 steel which is heated from the 1st temperature of 300 ℃, the 2nd temperature of 500 ℃ to 900 ℃ results in a hardness value that is relatively increasing, by using a method of quenching with water rapidly. The hardness value that was obtained before heat treatment averaged 52.62 VHN while after the heat treatment of ST37 steel obtained a hardness value of 85.56 VHN, the results of the impact test on ST37 steel averaged 52.73 Joules, this indicates that heat treatment of ST37 steel can increase the mechanical characteristics of the material with heating up to 900 ℃.

Abstract

Energi matahari adalah energi yang saat ini menjadi energi alternative yang bisa dikonversi menjadi energi listrik, hanya saja pemanfaatan efetivitas pengkonversian energi nya menjadi daya listrik perlu di perhatikan dengan baik, teknologi solar tracking menjadi salah satu teknologi tebaik dalam memanfaatan efesiensi penyerapan energi matahari menjadi energi listrik, penelitian ini lebih difokuskan untuk merancang dan malakukan fabrikasi dari system mekatronika solar panel yang sifatnya portable, dimana dalam desainnya menggunakan beberapa perangkat mechanical serta electronica, yang terdiri dari desain konstruksi berupa besi hollow 4x4x1 dan bearing serta motor DC gearbox, sedangankan untuk desain electronica nya menggunakan beberapa perangkar seperti, Sensor LDR, Sensor proximity infra red, Real Time Clock, Driver motor L298, sensor arus ACS 712. Desain perangkat mechanical dan electronica tersebut di proses secara fabrikasi dan assembling satu sama lain sehingga menjadi alat solar panel portable untuk skala rumah tangga yang di pasang diatas atap rumah dengan berbagai kondisi   atap rumah searah sumbu X ataupun sumbu Y dari arah matahari terbit. Desain yang di teruskan kedalam proses fabrikasi dan menjadi bentuk alat portable solar panel setelah itu dilakukan pengujian dan ditampilkan data pengujian secara random pada jam 08 00 Wib, 12 00 Wib dan 15 00 wib dan menghasilkan beberapa data pengujian yaitu, pada jam 08 00 didapat arus sebesar 4,00 A, tegangan 15,86 V, intensitas ahaya 12958 Lux, serta sudut kemiringan solar panel 480. Pada   jam 12 00   didapat arus sebesar 4,62 A, tegangan 15,53 V, intensitas ahaya 17033 Lux, serta sudut kemiringan solar panel 900 . sedangkan pengujian jam 15 00 didapat arus sebesar 3,66 A, tegangan 15,06 V, intensitas ahaya 9308 Lux, serta sudut kemiringan solar panel 1290.
