Abstract

Saklar manual yang dipakai pada sebuah gedung memiliki kekuranganyaitu pada selepas jam kerja petugas khusus harus jalan berkelilinguntuk mengecek apakah ada lampu yang belum dipadamkan. Tujuanpenelitian ini adalah untuk mengembangkan sebuah alat untukpenyaklaran lampu secara terpusat, yang dapat digunakan untukmenghidupkan atau mematikan lampu dan memonitornya dari jarakjauh berbasis sistem mikrokontroler dan personal computer (PC). Sistemberbasis mikrokontroler digunakan untuk mengukur besarnya arusyang mengalir kemudian mengirimkannya ke PC dan menghasilkanperintah untuk menghidupkan atau mematikan lampu. PC yang berisiprogram aplikasi mempunyai fungsi untuk menampilkan konsumsidaya berdasarkan arus yang diterima dari sistem mikrokontrolersecara real time dan mempunyai fasilitas saklar dan tombol virtualyang bisa digunakan untuk menghidupkan atau mematikan lampu.Pengujian dilakukan dengan dua tahap: pengujian per blok danpengujian keseluruhan. Hasil pencatatan daya pada PC dicocokkandengan perhitungan secara teoritis untuk rentang waktu sekitar 3minggu pengamatan secara kontinyu untuk mengecek akurasinya. Hasilpengujian menunjukkan lampu bisa dihidupkan dan dipadamkandengan menggunakan tombol program aplikasi. Tampilan daya di PCmempunyai kecocokan dibandingkan dengan perhitungan secarateoritis.

Abstract

Range extender engine is one of the main components of the range-extended electric vehicle (REEV) and together with a generator to extend the mileage of the electric vehicle. The main component of REEV is an electric motor, battery, and generator set that consist of generator and engine. In this study, we compared two models of REEV performance with two different types of the engine by simulation. Single cylinder 499 cc gasoline engine and single cylinder 667 cc diesel engine are chosen as the object of this research especially relating to the utilization of the fuel consumption and CO2 emissions when fitted to an electric vehicle. The simulation was conducted by using AVL Cruise software and performed by entering the data, both experiment and simulation data, on all the main components of REEV. This simulation was performed in Japan 08 driving cycle. Based on the simulation, fuel consumption is reduced up to 35.59% for REEV with single cylinder diesel engine 667 cc compared to REEV with single cylinder gasoline engine 499 cc. The reduction of CO2 emissions from REEV with single cylinder 499 cc gasoline engine compared to REEV with single cylinder 667 cc diesel engine up to 30.47%.

Abstract

Efforts to find alternative fuels and reduce emissions of CI engines have been conducted, one of which is the use of diesel hydrogen dual fuel. One of the goals of using hydrogen in dual-fuel combustion systems is to reduce particulate emissions and increase engine power. This study investigates the thermal efficiency and emission characteristics of a diesel-hydrogen dual fuel CI engine at various loads condition. The hydrogen was used as a secondary fuel in a single cylinder 667 cm3 diesel engine. The hydrogen was supplied to intake manifold by fumigation method, and diesel was injected directly into the combustion chamber. The results show that the performance test yielding an increase around 10% in the value of thermal efficiency of diesel engines with the addition of hydrogen either at 2000 or 2500 rpm. Meanwhile, emission analyses show that the addition of hydrogen at 2000 and 2500 rpm lead to the decrease of NOx value up to 43%. Furthermore, the smokeless emissions around 0% per kWh were occurred by hydrogen addition at 2000 and 2500 rpm of engine speeds with load operation under 20 Nm.

Abstract

This research was implementing vehicle networking using WIFI connection and computer vision to measure the distance of vehicles in front of a driver. In particular, this works aimed to improve a safe driving environment thus supporting the current technology concept being developed for inter-vehicular networking, VANET, especially in its safety application such as Overtaking Assistance System. Moreover, it can wirelessly share useful visual information such as hazard area of a road accident. In accordance with Vehicle-to-Vehicle (V2V) concept, a vehicle required to be able to conduct networking via a wireless connection. Useful data and video were the objects to be sent over the network established. The distance of a vehicle to other vehicles towards it is measured and sent via WIFI together with a video stream of the scenery experienced by the front vehicle. Haar Cascade Classifier is chosen to perform the detection. For distance estimation, at least three methods have been compared in this research and found evidence that, for measuring 5 meters, the iterative methods shows 5.80. This method performs well up to 15 meters. For measuring 20 meters, P3P method shows a better result with only 0.71 meters to the ground truth. To provide a physical implementation for both the detection and distance estimation mechanism, those methods were applied in a compact small-sized vehicle-friendly computer device the Raspberry Pi. The performance of the built system then analyzed in terms of streaming latency and accuracy of distance estimation and shows a good result in measuring distance up to 20 meters.
