Fabrication of inducting heating system for heating treatment in S50C materials have been done. This inducting heating system has dimensions of 350x230x200 mm, the input voltage of 12 VDC, equipped with a timer control and ampere meter as an indicator of output current. Inducting heating system testing on the material S50C was done by varying tempering process (30, 60, 90, 120 and 150 s). Hardness and microstructure test using Auto Vikers Future Tech type FV-300. The results showed that the hardness increased with increasing tempering time from 191 Hv to 572 Hv. S50C materials microstructure was transformed from ferrite and pearlite phase into martensite phase.

Judul: Rancang bangun pembangkit listrik tenaga sampah (PLTSa) di lingkungan Universitas Singaperbangsa Karawang Title: Design and build a waste power plant (WPP) at the University of Singaperbangsa KarawangSampah merupakan salah satu permasalahan yang terus dicari solusinya. Volume sampah dari hari ke hari terus meningkat dan menjadi masalah yang serius di Kota Karawang khususnya lingkungan Universitas Singaperbangsa Karawang. Salah satu pemanfaatan sampah yaitu mengubahnya menjadi energi listrik. Salah satu alternatif untuk mengolah sampah menjadi energi listrik yaitu dengan menggunakan pembangkit listrik tenaga sampah (PLTSa). Pembangkit listrik tenaga sampah terdiri dari komponen-komponen utama seperti boiler, incinerator, turbin, generator, control panel, dan juga rangka utama. Material yang dibutuhkan untuk membuat PLTSa adalah plat stainless steel, plat besi, besi behel, kuningan, besi L, besi hollow, batu bata, semen, pipa besi, dan pipa stainless steel. Dalam proses pengujian didapat data pembakaran dengan sampah heterogen atau campuran selama 180 menit didapat tekanan maksimal 5 bar, temperatur ruang bakar 162,2°C, dan menghasilkan tegangan alternator sebesar 21,9 volt. Pada pembakaran dengan kayu selama 135 menit didapat tekanan 5 bar dan temperatur ruang bakar 205,4 menghasilkan tegangan alternator 22,1 volt.Garbage is one of the issues that are still being resolved. The trash volume continues to grow and has developed into a severe issue in Karawang, particularly at the University of Singaperbangsa Karawang. Converting trash into electrical energy is one of the waste applications. Utilizing a waste power plant (WPP) is one method of converting garbage to electrical energy. The waste energy plant comprises many significant components, including boilers, incinerators, turbines, generators, control panels, and the mainframe. Stainless steel plates, iron plates, stirrup iron, brass, L iron, hollow iron, bricks, cement, iron pipes, and stainless steel pipes are the materials required to manufacture WPP. The test procedure produced a maximum pressure of 5 bar, a combustion chamber temperature of 162.2°C, and an alternator voltage of 21.9 volts using data acquired from 180 minutes of burning with heterogeneous or mixed trash. After 135 minutes of burning wood, the pressure in the combustion chamber is 5 bars, and the temperature is 205.4 degrees, producing an alternator voltage of 22.1 volts.

The clutch is a component of a mechanical system to transmit the rotational force of a motor or generating machine to the shaft which is connected to other mechanical components. In the mechanical world there are several types of couplings used in mechanical systems, namely: non-fixed couplings and fixed couplings. the clutch remains a clutch that does not allow it to be released while the engine is still running. This type of clutch is usually connected using bolts. So the stresses that occur in this coupling are usually mostly shear stresses on the bolts. This change focuses on bolts and nuts as a fixed coupling connection. Planning of nuts and bolts on flange couplings is a basic requirement that is really needed in this planning, carried out using experimental methods, by analyzing the dimensions, physical quantities of the planning components of nuts and bolts. Based on the results of calculations from the design of the flange coupling, the following data are obtained: Bolt Type = M20, Pitch Distance = 2.5 mm, Outside diameter (db) = 20 mm

Brakes are components that are used to slow down or stop the rate of engine movement by converting motion into heat and regulating the speed of decreasing the load. (Sonawan, 2015:). The design of brake components is carried out in order to get the appropriate design results. There are several factors that need to be considered when designing brakes, namely braking force, torque, braking power, wear volume, life time and materials. From the calculation results, the value of the service life is 7.35 months, the Braking Torque is 105.8 N.m, and the canvas material is Asbestos pressed hydroulically with plastic

Perkembangan teknologi yang memicu lahirnya revolusi industri salah satunya adalah ditemukannya mesin uap atau boiler. Harga bahan bakar terus merangkak naik, maka banyak perusahaan berusaha untuk menekan pemakaian bahan bakar tanpa mengganggu proses produksinya. Metode untuk menaikan efisiensinya adalah dengan memanfaatkan gas panas yang terbuang dari cerobong bila temperaturnya masih cukup tinggi (diatas 200ºC). Gas buang tersebut dapat digunakan untuk memanaskan air pengisi boiler atau memanaskan udara pembakar bahan bakar boiler (ekonomiser). Ekonomiser adalah alat penukar kalor yang memindahkan gas asap hasil pembakaran ke air pengisian boiler. Pada penelitian ini fokus kepada analisis performa alat penukar panas shell and tube. Dari data yang diperoleh hasil analisis daya penukar panas adalah 165477 W. Hasilnya hampir sama dengan output dari program HTRI yaitu 166700 W. Kualitas alat penukar kalor yang direncanakan dapat dilihat dari nilai efektivitas dan faktor pengotoran dari alat yang direncanakan. Nilai efektivitas perencanaan ini bernilai 51 % dan faktor pengotoran bernilai 0,00289 ºC.m²/W.
