Abstract

This research is an initial research in the development of cars with compressed air engine drivers. Modifications are made to the engine of 2-stroke motorized vehicles fueled by gasoline. Pressurized actuators using selenoid valves are ordered based on the piston position obtained from the proximity sensor. When the proximity sensor detects the piston is in the TMA position, the selenoid valve is ordered to open so that pressurized air enters the combustion chamber and pushes the piston to move to the TMB and turns back to TMA. The selenoid valve will close again when the proximity sensor detects that the piston is moving from TMA to TMB. Pressurized air is given to move the piston to produce a spin on the wheel. Air pressure is given at 0.92 bar to 2.36 bar resulting in a maximum rotating speed of 1035 rpm, torque of 1.33 Nm, and maximum power of 0.71 kW based on the results of static testing. This research will continue to be developed to optimize the torque and power produced so that cars driven by compressed air engines can be produced.

Abstract

The automatic control system also able to implement using arm robot concept. In this research, 5 DOF (Degree of Freedom) arm robot control system using the close – loop control methode with the MPU 6050 Sensor which integrates the rotation of MG995 motor servo as feedback.Control of this robot using android – based aplication, the app send data of rotate angle for each servo motor which will rotate to a certain angle, afterward the data received by HC – 05 Bluetooth and the arduino UNO R3 process its data. Arduino UNO R3 microcontroller can control every rotation of each servo motor that integrated with an MPU6050 sensor with serial monitor communication to display the rotation of each servo motor. The test results obtained by the standard deviation value shows how large the sample diversity is. The result of this research show standard deviation correlation with the number of sample diversity. The higher standard deviation value will indicate more sample data spread (data diverse or varies), otherwise smaller standard deviation value will indicate homogenous sample data, and if standard deviation equals to zero it indicates sample has identical data. The highest standard deviation value from servo motor 1 is 5.20, servo motor 2 and 3 are 1.00, servo motor 4 is 2.89, and servo motor 5 is 2.9.

Abstract

In this research, the underwater robot designed is a type of mini Remotely Operated Vehicle (ROV) based on the Arduino Uno Atmega 328A microcontroller. This research was aimed to make a robot underwater or ROV and test its performance in water. This research was conducted to determine the system of tightness in the ROV by using a body that was used as a cover for each component in the ROV and tested its movement in the water. The design of mini ROVs is integrated in several design processes, namely planning the calculation of each component selection used by ROV, designing mechanical construction, designing electronic construction, and making integration of the entire design process. The results of this integration are in the form of a physical form of mini ROV, electronic systems, and graphical interface programs. The designed robot is an underwater robot that can move in water with the X, Y and Z axes. The ROV robot is made with a total dimension of 38 cm in length, 21 cm in width, and 22 cm in height. The body of the ROV is made using a base material from a PVC pipe that each gap is lined with a seal so that the ROV can be maintained properly. In the ROV movement system, use 2 propeller leaves to go forward and backward and 2 propeller leaves to drown or raise the ROV.

Abstract

Differential gears are one of the round transmission systems on cars, where the electric motor is the main activator of the electric car that has been integrated with the differential gear so the rotation of the electric motor is directly transmitted to the rear activator differential gear. In this study, an electric motor uses a 2200 W DC 60 v brushless motor, BLDC, motor, BM1424HQF-14A motor type. The maximum torque in the final gear is 600 Nm. This study focused on calculating the ratio of differential gears, tangential forces that occur on gears, calculation of gear torque. From the results and discussion on the calculation of the maximum torque in the final gear of 600 Nm, the maximum torque results in the pinion gear are obtained. When the pinion gear speed is at 1 rpm, the torque force generated is as large as it can be stated that the gears are safe to use with a motor power of 2.2 kW.

Abstract

Penelitian ini mempelajari karakteristik suspensi sadel sepeda jalan baja karbon rendah. Analisis sifat tekuk baja, nilai kekerasan, dan struktur mikro dengan menghadirkan proses annealing pada suhu 800oC. Berdasarkan hasil penelitian, pegas daun tanpa proses annealing diagonal 50 mm mengalami patah ketika pegas bengkok, pada gaya 546,28 kgf. Pada saat pegas daun tanpa proses annealing pegas daun rentan terhadap fraktur karena terdapat fase ferit dan fase perlite di mana pada sifat ini lebih banyak ferit terbentuk, bahan semakin lunak dan liat. Pengujian pegas daun yang telah dipasang di sadel sepeda jalan dengan diameter lekukan 50 mm dan diberi beban 75 kg mengalami defleksi dan menyebabkan tidak kembali ke posisi awal dibandingkan dengan pegas daun diameter lekukan 70 mm dan diberi beban 75 kg di mana diameter lekukan adalah 70 mm ketika diberi beban pegas dari lekukan 70 mm kembali ke posisi awal ketika pegas diberi beban.

Abstract

Sumber energi panas bumi di Indonesia dapat dimanfaatkan untuk pembangkit listrik. Oleh karena itu dibuatlah siklus Organic Rankine Cycle (ORC) pada alat penukar kalor tipe shell and tube dengan aliran crossflow. Pada proses penukaran kalor akan dipelajari koefisien perpindahan panas menyeluruh, beda suhu rata-rata, dan NTU-Efektifitas dengan menggunakan metode LMTD (Logarithmic Mean Temperature Difference) dan  NTU (Number of  heat Transfer Unit). Dari hasil perhitungan dan analisis, perpindahan panas yang dihasilkan sebesar 335,22 kJ/s pada ?Th 2 0C, LMTD 9,64 0C, koefisien perpindahan panas 50,25 kW/m2 0C, dan NTU-efektivitas 2,8 dan 0,83 sehingga dapat disimpulkan semakin besar perbedaan suhu masuk dan keluar maka semakin besar juga perpindahan panas. LMTD dipengaruhi besar kecilnya faktor koreksi dan suhu masuk atau keluar pada shell and tube,oleh karena itu semakin besar LMTD yang dihasilkan. Untuk NTU-efektivitas, semakin kecil perbedaan antara qaktual dan qmaks, semakin besar nilai efektivitas yang dihasilkan. Hal ini berbeda dengan NTU yang mana semakin besar perbedaan antara efektivitas dan kapasitas (C) atau ?c.Cpc/ ?h.Cph maka semakin besar juga nilai NTU yang dihasilkan.

Elemen peltier merupakan alat thermoelectric yang di dalamnya terdapat bahan semi konduktor. Thermoelectric merupakan alat yang mempunyai dwifungsi/2 fungsi penggunaan, yaitu sebagai pebangkit energi listik (TEG) dan sebaga penghasil dingin (TEC). Dan dari hasil pembelajaran tersebut penulis ingin mengaplikasikannya Pengaplikasiannya salah satunya dengan mendesain mini generator 12V  dengan menggunkan energi panas dari hasil pembakaran atau kompor biomasa. Hal ini nantinya akan bermanfaat untuk digunakan di daerah–daerah atau di pegunungan yang belum teraliri listrik.
