Abstract

The heat treatment process using the fuel system is very numerous and the heating time is quite long. The use of induction heaters, heat treatment can be done with a shorter time and less energy. The purpose of this research are; (1) Make a plan design, (2) Measure the part of machine element, (3) Measure the estimation of time and design budget, (4) Test the result of induction heater machine. The method in this study uses experimental. The result of concept design evaluation, i.e., the use of trapezoid screw on the lifter system was 0,2 kilowatt of motor power, 12 mm of shaft diameter, and ball bearing 6201 with the age of 0,31 years which determined from the calculation of machine element on the induction heater system. The total of time for making this machine was 3.182,06 minutes and it spent Rp 5.360.700,-. The result of test shows that the hardness rate of raw material mild steel that given heat of hardening temperature of 850 0C, that endured for 45 minutes increasing being 84,3 HRB. However, after being tempered temperature of 400 0C having a decrease being 69 HRB.

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

The bending test machine for composite materials is a machine designed as material testing tool, especially composite materials. The objectives achieved are to design and manufacture a bending test machine as well as to test the composite material of epoxy resin and sugarcane powder based on the ratio of weight fractions. The machine design method uses the VDI 2222 method approach. From the method carried out, the results obtained from the design of the bending test machine using Solidwoks 2017. The design results of the bending test machine with dimensions of length 500 mm, width 500 mm, and height 1.400 mm, which consists of several main components including: frame; suppression system; and supports. The estimated time of the bending test machine production process takes 51,69 hours or 7 days. The results of the composite material test resulted in the bending strength of the 100% resin weight fraction of 67,71 Mpa and the 50% sugarcane powder weight fraction of 33,74 Mpa.
