<![CDATA[Meningkatnya kebutuhan manusia dalam bidang transportasi, pemakaian bahan bakar minyak juga semakin meningkat. Apabila hal ini dibiarkan secara terus menerus maka masyarakat akan kesulitan memenuhi kebutuhan pokok sehari-hari akibat dari harga bahan bakar minyak yang melambung tinggi. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh RPM dan kevakuman pada MAP (Manifold Absolute Pressure) Sensor terhadap konsumsi bahan bakar dan emisi gas buang dan untuk mengetahui MAP Sensor yang paling efisien konsumsi bahan bakarnya. Metode pengujian yang dilakukan diantaranya mengatur putaran mesin dengan membuka katup gas menggunakan sekrup dan melihat pembacaan putaran pada speedometer selama proses pengujian, Mengukur volume bahan bakar yang dikonsumsi mesin oleh MAP Sensor dengan cara menyambungkan tangki bahan bakar dengan pipa plastik transparan kemudian mesin dibunyikan selama 20 detik, kemudian melihat perubahan volume pada pipa transparan dan mengukurnya menggunakan mistar baja, dan mengukur emisi gas buang yang dihasilkan mesin oleh MAP Sensor menggunakan emission gas analyzer. Terjadi perubahan konsumsi bahan bakar dan emisi gas buang yang dihasilkan akibat MAP Sensor yang berbeda. RPM dan kevakuman pada MAP (Manifold Absolute Pressure) Sensor berpengaruh terhadap konsumsi bahan bakar dan emisi gas buang. MAP yang paling irit dan ramah lingkungan adalah MAP 89420-12040.]]>

<![CDATA[Ceria Centre is one of the institutions engaged in the consultant psychologist and there are some participants who are experiencing autism. When observing the information, the autistic child requires media for the identification of the surrounding objects that are visual and audio. In this institution in the presentation of the introduction of objects for autistic children still use traditional tools, namely the form of beams. This way is considered less efficient because it often breaks or loss of the introduction beam and does not cover the possibility of human error as well. The author devised an interactive Android-based recognition application as a media helper of the introduction of objects around by loading the needs required by the autistic child, by giving a simple look that contains the introduction of alphabets, numbers, Limbs, animals, fruit and spelling of words and accompanied by audio. This application is designed using construct 2 using the waterfall development method. This research generates an Android-based object recognition application designed according to what the autistic child needs. In general this application can make it easier for children to increase their knowledge with a percentage of 70%.]]>

<![CDATA[Cases of motor vehicle theft are still common in the environment around us. The main cause is the knowledge of criminals, the dominant motorcycle security system is the same in every other motorcycle unit that uses a steering handlebar safety lock. Therefore the need for additional safety systems is felt very necessary to avoid motor vehicle theft. From the four tests conducted, the level of accuracy of location scanning by GPS experienced a difference in each test, this is due to the strength of the network received by the GPS device between the two devices, both from the researchers' GPS device and the GPS device attached to the vehicle unit, decreasing the relative accuracy between 6.8% and 17% in testing. The speed of response of the safety device is very dependent on the signal strength and the place where the vehicle or vehicle owner is owned by each provider, from the test delay calls are 3,2 seconds results,it was concluded that TELKOMSEL providers who have a more stable network.This is evidenced by the difference in the time of receipt of the response of vehicle safety devices when testing telephone delay calls and GPS testing. The advantage of this tool is that the assembling of components is quite simple compared to other electrical safety devices so that it is easy to peruse]]>
