Abstract

The chassis is the main part of a vehicle that functions to hold all components and passengers and must be able to withstand the loads that occur without experiencing excessive deflection or deformation. Off-road cars are designed to be able to pass on unpaved roads or terrain or rocky surfaces. With such terrain, it will put an excessive burden on the car, especially on the frame. The frame will be subjected to greater bending and torsional loads if the car is used on an uneven surface. For that we need a frame that is strong and rigid so that it is safe for the driver and other car components. In this study, an analysis of the stress that occurs on the frame of the TM D3 Off-Road Car was carried out to determine its strength. The analysis was carried out numerically using the finite element method using SolidWorks software. The results of the analysis show that under a static load of 3000 N, the frame is still in a safe condition because the stress that occurs in the frame is below the yield stress value of the material used, while at a torsional loading of 500 N.m, the frame is in an unsafe condition because the stress that occurs exceeds the value the yield stress of the material used. After modifying the frame, the simulation results with 500 N.m torsional loading show that the stress that occurs in the frame is in a safe condition.

Abstract

Pada motor matic dipengaruhi oleh beberapa faktor salah satunya yaitu bergeraknya sliding sheave yang ditekan oleh pemberat atau roller berdasarkan putaran mesin, jika pemberat atau roller semakin ringan maka menyebabkan puli lebih melebar. Maka perlu dilakukan penyesuaian berat roller dengan tujuan agar mendapatkan tenaga yang optimal sehingga mampu melakukan akselerasi yang lebih tinggi. Motor yang akselerasinya tinggi membutuhkan lebih banyak bahan bakar untuk menghasilkan tenaga yang lebih besar. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh berat roller CVT terhadap torsi, daya dan konsumsi bahan bakar spesifik. Untuk pengujian torsi dan daya dilakukan dengan alat dinojet 250i pengujian dilakukan pada rpm 5500 rpm, 6000 rpm, 6500 rpm dan 7000 rpm. Untuk pengujian konsumsi bakar spesifik alat yang digunakan adalah burret, pengujian dilakukan dengan cara melihat pengurangan bahan bakar pada burret selama 30 detik dilakukan pada rpm 5500 rpm, 6000 rpm, 6500 rpm dan 7000 rpm. Dari data pengujian torsi dan daya menunjukkan bahwa masing-masing roller akan mengalami peningkatan grafik data pengujian torsi dan daya disetiap rpm dan dari data pengujian konsumsi bahan bakar spesifik menunjukkan bahwa masing-masing roller akan mengalami penurunan grafik data pengujian konsumsi bahan bakar spesifik di setiap rpm.

Abstract

To design a transmission shaft requires quite complicated calculations, the calculation time is also quite long and the calculations must be careful because they are done manually, as has been done so far. The calculation results must also be accurate because the size of the shaft that does not meet the requirements can result in failure. To meet these needs, calculations in shaft design can be done with a tool, namely a software application that is run on a computer. The purpose of this study is to produce a software application or machine element calculator for shaft planning using the Matlab GUI, and to increase the efficiency of shaft planning in terms of time. This machine element calculator is designed by selecting the Matlab GUI menus according to the calculation formulas for the torsional load shaft diameter, namely Edit Text, Static Text, Panel and Push Button. Then arrange and edit the GUI menus through the Property Inspector and create a program (Matlab Code) for calculating the shaft diameter through the Callback menu. With this calculator, calculations in transmission shaft planning can be accelerated, which is an average of 24.8 minutes faster than manual calculations, which is an average of 34.8 minutes.

Abstract

Waste is a significant problem that needs to be urgently addressed. If waste is left untreated and disposed of improperly, it can become contaminated by bacteria, viruses, and other toxins that pose serious risks to humans. In this study, researchers designed and created a portable incinerator that utilizes used oil fuel. The study aimed to determine the highest temperature that can be achieved when incinerating wet and dry waste at weights of 5000 grams, 3000 grams, and 1000 grams. Additionally, performance of portable incinerator was evaluated based on the combustion rate and fuel consumption. The result show that the maximum temperature generated by both dry and wet waste is 450 degrees Celcius. The maximum volume of waste that can be loaded into the combustion chamber is 5000 grams. The results show that the maximum combustion rate of the portable incinerator for dry waste weighing 1000 grams is 196.85 gr/s.The maximum burning rate for wet waste weighing 1000 grams is 165.56 gr/s. The minimum fuel consumption produced from dry waste weighing 1000 grams is 300 ml of used oil. And the maximum fuel consumption is produced from wet waste weighing 5000 grams, namely 1000 ml of used oil.

Abstract

At-Tajdid salah satu pondok pesantren (ponpes) modern yang menyiapkan Muslim Berkemajuan sebagai kader persyarikatan maupun kader bangsa yang berintegritas, sebagai penyelenggara pendidikan di dalam pondok pesantren tentunya terdapat fasilitas pendukung proses belajar mengajar santri/santriwati yang saat ini berjumlah 215 orang. Untuk akses masuk-keluar lingkungan ponpes terdapat gerbang terbuka karena belum/tidak ada pintu yang membatasi akses ke dan dari lingkungan pondok pesantren. Selama ini, siapapun bebas masuk/keluar lingkungan ponpes, baik siang maupun malam. Dengan kondisi seperti itu, maka permasalahan yang dihadapi mitra adalah kerawanan lingkungan terhadap terjadinya kejahatan, utamanya kasus pencurian di lingkungan pondok pesantren. Hal ini disebabkan tidak adanya kendali akses di pintu gerbang. Berdasarkan situasi dan kondisi yang dihadapi mitra tersebut, maka solusi dan target luaran yang ditawarkan dalam program PkM ini yaitu Mitra dibuatkan pintu atau portal yang dipasang pada gerbang pondok dengan sistem buka-tutup pintu atau portal dibuat semi-otomatis bertenaga surya guna membatasi akses masuk/keluar lingkungan pondok pesantren. Dengan adanya pembatasan tersebut, dapat memberikan rasa aman dan nyaman bagi seluruh penghuni di lingkungan pondok pesantren, sehingga konsentrasi proses belajar mengajar meningkat.

Abstract

Cooling media is one of the factors that affect the quality of welding results. One indicator of the quality of welding results is the tensile strength test. This test is carried out to ensure the maximum tensile strength or stress that can be sustained by the material and its ability to withstand certain mechanical loads. This study was conducted to determine the effect of several types of cooling media, namely free air, distilled water, and SAE 40 oil on the tensile strength of SCH 40 carbon steel pipe material after being welded with SMAW welding. The conclusion obtained from the test data regarding the effect of cooling media on SMAW welding of SCH 40 carbon steel pipe material shows that cooling media with SAE 40 oil has the highest tensile strength and strain values of 714.38 N/mm2 and 6.19%, while the lowest tensile strength value is produced in distilled water cooling media, namely 592.44 N/mm2 and 4.33%.
