Abstract

Kendaraan bermotor di Indonesia yang menjadi sumber emisi gas buang terbesar adalah sepeda motor. Ini merupakan kurangnya perhatian pengguna kendaraan bermotor dengan perbandingan kompresi mesin kendaraan yang tinggi cenderung memilih mengisi bahan bakar sepeda motornya dengan premium yang harganya lebih murah namun memiliki angka oktan yang rendah. Hal ini tentu akan menimbulkan masalah terhadap pembakaran yang tidak sempurna. Efek yang ditimbulkan adalah menyebabkan meningkatnya polutan pencemaran udara. Untuk mengatasi permasalahan diatas adalah dengan cara menggunakan Hydrocarbon Crack System (HCS), HCS bekerja untuk menyempurnakan proses pembakaran, sehingga dapat menurunkan kadar emisi gas buang kendaraan. Tujuan dari penelitian ini melihat pengaruh penggunaan Hydrocarbon Crack System (HCS) terhadap performa dan kandungan emisi gas buang yang dihasilkan. Berdasarkan hasil penelitian diperoleh bahwa penggunaan HCS pada sepeda motor Honda Supra X 125 dapat menurunkan emisi gas CO sebesar 40 %. Untuk emisi gas HC penggunaan HCS dapat menurunkan emisi gas HC sebesar 37%,sedangkan untuk emisi gas buang CO2 penggunaan HCS dapat meningkatkan emisi gas CO2 sebesar 12.98%. Motor vehicles in Indonesia which are the largest source of exhaust emissions are motorbikes. This is the lack of attention of motorized vehicle users with high engine compression ratios, which tend to choose to refuel their motorbikes with premium which is cheaper but has a low octane number. This of course will cause problems with incomplete combustion. The resulting effect is to increase air pollutants. To overcome the above problems is by using the Hydrocarbon Crack System (HCS), HCS works to improve the combustion process, so that it can reduce the levels of vehicle exhaust emissions. The purpose of this study is to see the effect of the use of the Hydrocarbon Crack System (HCS) on the performance and content of the resulting exhaust emissions. Based on the research results, it was found that the use of HCS on a Honda Supra X 125 motorcycle could reduce CO gas emissions by 40%. For HC gas emissions, the use of HCS can reduce HC gas emissions by 37%, while for CO2 exhaust emissions, the use of HCS can increase CO2 emissions by 12.98%.

Abstract

The safety of a motorcycle is very important for vehicle owners. Until now, most motorbikes still rely only on the key to contact the vehicle itself. In the case of vehicle theft, it is very easy for the perpetrator of the theft to use the letter "T" key. Therefore an additional vehicle safety is required which is difficult to break apart from the ignition key. The purpose of this research is to design and implement motorcycle safety using Arduino-based Radio Frequency Identification (RFID) as additional vehicle safety. The author uses an RFID card / tag to add security to the vehicle starting system with a card / tag reading distance that can be read by an RFID reader. The ID code on the RFID Card must be inputted into the Arduino so that the RFID reader can read the ID Card that has been inputted into the Arduino. Based on the results of the tests that have been done, it is found that the reading distance of the RFID Card / Tag ranges from 1 cm to 3.5 cm. If the correct ID code is inputted, the electrical system is active and vice versa if the ID code entered is wrong, the buzzer will sound and the electrical system in the vehicle is not active / does not turn

Abstract

Palm Oil Mill PT. Surya Intisari Raya, Sei Lukut is a plantation company engaged in the commodity palm oil FFB (Fresh Fruit Bunches), with output in the form of CPO (Crude Palm Oil) and Palm Kernel (PK). There are 13 processing stations at PKS that have high noise levels, one of which is a sterilizer station which can disrupt operator psychology, namely Sleep Disturbance. In the field survey, it was found that operators experienced concentration problems such as drowsiness, and not all of them used ear protection in the form of earplugs/earmuffs. Therefore, it is necessary to identify the noise level at the sterilizer station and to analyze its effect on the operator's sleep quality using an observational analytic cross-sectional approach. Noise in the workplace was measured using a sound level meter and the sleep quality of workers was measured using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Based on the results of noise level measurements, 4 processes have noise above the Threshold Limit Value, namely Deaeration of 89.824 dB, Containment of 92.548 dB, Peak BlowDown by 2 of 96.45 dB, and Final of 102.77 dB. Based on the results of the Pittsburgh Sleep Quality Index (PSQI) questionnaire, 100% of Morning Shift and Night Shift workers have poor sleep quality. To overcome this problem, several suggestions were made, namely to carry out periodic health checks for operators, ensure that operators who are exposed to noise always wear an earplug/earmuff, and minimize exposure to noise above the NAB to operators by keeping noise points away from the operator's premises.
