The increase in NOx levels produced by CNG-fueled engines occurs when the fuel switches from gasoline to gas fuel (CNG). The author changed the otto 4 stroke gasoline engine, into a CNG-fueled motorbike and provided additional cooling in the form of a burst of air to the cylinder block. Changes in engine block temperature are detected using a temperature sensor placed on the engine oil. Bursts of air cooling result in temperature changes in engine oil. Changes in engine oil temperature are accompanied by changes in the resulting NOx emissions. This study shows that with a decrease in engine oil temperature in the combustion engine, NOx emission levels also decrease. From the research results it can be ignored that by providing additional air bursts will be able to reduce NOx emissions by up to 18%

Each type of work has the risk of being affected by accidents or occupational diseases. These risks cannot be avoided, but can be minimized. Welding uses fire and flammable and explosive materials. Given the importance of Occupational, Safety and Health (OSH) in every workplace to increase work productivity, the implementation of OSH is the responsibility of all parties. Based on observations, many students were absent from lectures due to illness and some were exposed to gram splashes due to welding practices. Therefore, it is necessary to conduct further research on the application of Occupational health and safety culture as an effort to prevent accidents and diseases caused. The purpose of this research is to make procedure of preventive action on welding process. The research methodology consist of literature study, observation, make danger formulation and make critical assessment. The result of this research show that the highest RPN while the operator do welding.

Musculoskeletal disorder is one of the risks due to improper working position. The most common problems in UD. Jati Semi were started from woodcutting up to finishing processes were the poor material arrangement, unergonomic working position, and dust from the wood cutting process. The risk assessment was performed by HIRA (Hazard Identification, Risk Assessment) method. The results showed that there were 4 risks in the accepted category, 1 risk in the moderate category, and 3 risks in the unaccepted category. The methods for analyzing working postures were performed by RULA (Rapid Upper Limb Assessment) and OWAS (Ovako Work Posture Analysis). The RULA results showed that the first installation and the cutting processes were classified as high-risk category, the second installation and the machine sanding processes were classified as the moderate-risk category, and the engraving by machine, the manual engraving, and the staining processes were classified as small-risk category. The OWAS results showed that the first installation, the sanding by machine, the engraving by machine, and the second installation processes were classified as the moderate category, the staining process was classified as quite category, the cutting process was classified as the highest category , and the engraving process was classified as the low category.

Community Empowerment Vol 7 No 2 (2022)
Publisher : Universitas Muhammadiyah Magelang

The efficiency of the production process in the home industry 'Tahu Taqwa Bintang Al Qomar' is a major issue, particularly in the soybean milling process. According to the owner, this procedure should be carried out elsewhere. The purpose of this program is to improve the efficiency of the soybean milling process, which is the primary source of tofu. Methods of this program include: 1) design of soybean grinding machine; 2) manufacture of design for soybean grinding machine with a capacity of 10 kg; 3) machine testing; and 4) training and assistance in operating the equipment to partners. The result of this community service activity is a soybean grinding machine product as a solution to partner problems, as well as increasing partner skills, especially in operating machines. This is to support the soybean milling process independently, so as to achieve the efficiency of the soybean milling process as a raw material for tofu.

Pembersihan Combustion Chamber Deposits (CCD) atau kerak ruang bakar mesin tanpa adanya repetisi (pengulangan), belum mampu menghasilkan pembersihan yang optimal yang terukur dari hasil pengujian kinerja mesin. Penelitian ini bertujuan untuk: 1) Mengetahui pengaruh pembersihan kerak karbon ruang bakar terhadap emisi gas buang CO dan HC pada gasoline indirect injection engine; 2) Mengetahui berapa kali repetisi (pengulangan) pada proses pembersihan kerak karbon ruang bakar yang menghasilkan nilai emisi gas CO dan HC yang paling rendah; dan 3) Mengetahui berapa jeda waktu repetisi (pengulangan) pada proses pembersihan kerak karbon ruang bakar yang menghasilkan nilai emisi gas CO dan HC yang paling rendah. Metode penelitian adalah eksperimen meliputi: Pengadaan dan persiapan alat serta bahan; proses perlakukan dan pengujian; ananlisis data; dan kesimpulan. Hasil Penelitian menunjukkan bahwa : 1) Pembersihan deposit karbon dari ruang bakar mesin telah mampu menurunkan kadar emisi gas CO dan HC secara konstan dalam berbagai putaran mesin; Repetisi (pengulangan) tidak begitu berpengaruh pada hasil penurunan kadar emisi gas CO dan HC; 3)Penjedaan waktu berpengaruh pada hasil penurunan kadar emisi gas CO dan HC. Nilai paling baik diperoleh dengan data repetisi dan penjedaan selama 20 menit.

Brown sugar is one of the natural sweeteners in the community. Where the sale of brown sugar has fluctuated due to the constant demand for brown sugar. Researchers aim to increase productivity and increase interest in brown sugar, so a new product is made, namely brown sugar with a ginger flavor. Therefore, the researchers made a ginger- flavoured brown sugar machine as a souvenir drink typical of the city of Kediri with a capacity of 150 liters/hour. the method used is a design method, which includes the planning stage, calculation, manufacture or assembly, and testing the machine. Which in this section explain more on the transmission system, which cover electric. In the results of the report above, it can be concluded that the planning for the number of scar teeth obtained a cylinder length of 90 mm and a cylinder diameter of 50 mm and the distance between the teeth of the scar 1 and the teeth of the scar 2 is 3 mm and the number of teeth planned for scarring is 840 teeth of the scar. The correction factor has a value of 0.186 kW. In machine testing, the comparison results obtained that 20 liters of brown sugar requires 1.134 kg of ginger and the grating process takes 13 minutes. Using an electric motor as a power source with a size of 1/4 HP, 220 volts, 200 watts and a speed of 2800 rpm. The quality of the grated ginger produced is very soft motor dynamo, grater eye, grater cover, fiter
