Abstract

Energy consumption in Indonesia is increasing every year, the fulfillment of the energy needed must be overcome. Energy is something that is really needed by anyone, from humans or animals to be able to do something or work. This energy is also abstract, its existence can be felt, but it is difficult to prove. Electricity needs of the community today are a basic need. Electricity usage is almost 24 hours nonstop. To cope with the increasing demand for electricity, it is necessary to utilize natural resources that can be used as new energy resources. The floating hydro power plant simulator is a hydroelectric power plant that utilizes the flow of water from a pump to drive a waterwheel, a device designed to make it easier for students to learn basic electrical engineering and fluid mechanics. The purpose of this design is to design and build a floating hydro power plant and test the tool. The design method used the VDI 2222 method approach, which includes planning, conceptualizing, designing, finishing. The results of the design were according to the method used, namely in the form of a waterwheel simulator design for power plants. The estimated production process time for the manufacture of a floating hydro simulator for cutting 3.9 hours; process of gurdi 3.08 hours; lathe process 1.3 hours; 1.58 hours assembly process; finishing process 2.75 hours = 1.2 days (1 day = 8 hours). The total cost of making the machine was Rp. 2.605,740.00. The driven pulley test results in 65.4 rpm and the driven pulley produced 304 rpm and the output was 12.3 volts.

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

Penanganan limbah saat ini terutama limbah plastik, oli bekas, styrofoam bisa dimanfaatkan menjadi batako ataupun batu bata. Dengan proses sederhana, limbah plastik, oli bekas, styrofoam dapat diubah menjadi produk yang lebih bermanfaat dengan harga bersaing dengan batako biasa. Namun pengujian sifat-sifat fisik batako limbah plastik, oli bekas, styrofoam sebagai bahan bangunan konstruksi masih belum banyak dilakukan. Melalui penelitian ini diharapkan kita dapat mengetahui keunggulan ataupun kelemahan karakteristik batako komposit sebagai bahan bangunan dibandingkan batako biasa.  Tujuan penelitian ini adalah untuk membandingkan karakteristik kuat tekan batako komposit pada beberapa variasi komposisi komposit. Campuran limbah plastik, oli bekas, styrofoam yang dikompositkan dalam batako adalah sebesar 20,26% volume. Campuran oli bekas, plastik, Styrofoam  dan pasir yang dikompositkan dalam batako adalah sebesar 20,26% volume. Cetakan dibuat dari plat baja tebal 3mm dibuat dalam bentuk balok ber alur lebar 150 mm sepanjang 500 mm sebanyak alur 2 buah. Hasil pemeriksaan kuat tekan dibandingkan berat batako oli bekas, plastik, Styrofoam  dan pasir komposisi cetakan III lebih ringan dari cetakan II meskipun voume komposit pada masing-masing cetakan tersebut sama. Hal ini disebabkan karena campuran penekanan pada cetakan II lebih padat daripada campuran pada cetakan III.

Abstract

Electric bike is environmentally friendly vehicle because it doesn’t cause air pollution and it can uses electric from renewable energy sources to charge battery. Here is a lot of studies about electric bike in Indonesa, but only a few topic about electric bike for uphill climbing. In this study, electric bike will be designed for a load of 80 kgs to overcomes the uphill road at 21° of elevation. The design process contains activity such as calculation and selection of electric motor, drafting and manfacturing the frame, and riding test on flat road and uphill road at 21° of elevation. The results of design, electric bike uses 2000 watt BLDC motor, 48V 20Ah of battery, 13 teeth at front sprocket and 48 teeth of rear sprocket. From the riding test results, the bike’s maximum speed is 35 km/h reached on 5 seconds on flat road. While on uphill road with elevation of 21°, the bike’s maximum speed is 10 km/h reached on 10 seconds. The conclusion from this study that the electric bike are able to meet the needs to overcome uphill road.
