Abstract

The outbreak of the Covid 19 disease has caused disaster to the people. The emergence of this disease’s outbreak encourages the importance clean lifestyle. In order not to easily contracted the Covid 19 disease, it is necessary to make automatic handwashing equipment to prevent people from having direct contact with the equipment. In this research the design and testing of an automatic handwashing equipment based on solar energy were carried out. The purpose of this research was to determine the capacity of the sun's intensity to provide electrical energy through the solar module to the battery which will be used to supply electrical energy of solar energy-based automatic handwashing equipment. The method used in this research was the Palh and Beitz method approach and the experimental method which started with the design, material selection, assembly and testing. The design produced equipment specifications for a solar module framework with a height of 100 cm, a width of 80 cm, a length of 100 cm, while for a sink frame with a height of 90 cm, a width of 45 cm, and a length of 55 cm. The test was carried out in three phases, phase one was testing the module input power. The module input power in the test produced a power of 2461 Watts with a solar radiation intensity of 3237 W / m2. The peak intensity and power of the sun was shown at 13.00 WIB. The second phase of the test was the length of time needed to charge the battery took 2.5 hours. The third phase of the test was the power needed for sensors and pumps of 358 Watts. The power requirement of 358 Watts could be supplied by a 100 Wp solar panel, since the power released from a 100 Wp solar panel is 400 Watts.

Abstract

Coffee Roaster Machine with Temperature Controller and Timer Capacity 1 Kg is designed to optimize heat from the heater and has a cheaper price than the machines on the market. The goal  in the design of Coffee Roasting Machine with Temperature and Timer is to design, manufacture, perform function tests and test the results of the machine. In the manufacture of this machine the author uses the design method approach of James H. Earle, image software using Solidworks 2017 and working drawings using ISO standards. From the methods that the authors do, obtained the results of the evaluation of the concept of draft decisions are Source pemerers using a DC electric motor with a 12 volt voltage, heat source using a heater with 1500 watts of power, and the total cost used to make this machine of  Rp. 4.296.912,32.

Abstract

Sistem pemindah tenaga merupakan bagian yang tidak terpisahkan dari sebuah unit kendaraan, komponen ini berfungsi sebagai penerus daya dari mesin, memperbesar momen yang dihasilkan mesin sesuai kebutuhan beban dan kondisi jalan serta membalikan putaran. Jenis Seiring usia pakai dari kendaraan maka transmisi yang digunakannya akan mengalami kerusakan atau bahkan gagal fungsi, sebagian besar transmisi otomatis mulai bermasalah setelah kendaraan digunakan diatas 100.000 km atau pada kendaraan yang tidak digunakan sesuai dengan ketentuan serta tidak melaksanakan prosedur perawatan  dengan baik maka kerusakan transmisi otomatis bisa datang lebih cepat. Berdasarkan penerapan metode Failures Mode Effects Analysis (FMEA) yang digunakan untuk mengevaluasi komponen pada suatu sistem dengan cara meneliti potensi model kegagalannya untuk menentukan dampak yang akan terjadi pada komponen atau sistem kerja ditemukan nilai Risk Piority Number (RPN) yang paling tinggi terdapat pada komponen Seal Piston Matic Sebesar 450, Multiple Clutch/Clutch Pack 360, Selenoid Valve 324. Setiap potensi dari model kegagalan diklasifikasikan berdasarkan dampak yang dapat ditimbulkan pada keberhasilan sistem tersebut ataupun pada keselamatan pengguna dengan pembagian katagori menggunakan  Logic Tree Analysis (LTA) dengan hasil sebagian besar komponen transmisi otomatis termasuk dalam kerusakan tipe B (Outage Poblem) dimana komponen tersebut mengakibatkan kegagalan pada seluruh atau sebagian sistem. Berdasarkan nilai RPN maka pemeliharaan yang tepat adalah Pemeliharaan Prediktif.
