Abstract

Penelitian ini bertujuan mengevaluasi pengaruh pemasangan catalytic converter aftermarket berbahan stainless steel (Brand KR 49 Racing, diameter 50 mm) terhadap kadar emisi gas buang karbon monoksida (CO) dan hidrokarbon (HC) pada sepeda motor Honda Beat FI seri KZL tahun 2014. Metode yang digunakan adalah eksperimen dengan dua kondisi pengujian, yaitu knalpot standar tanpa catalytic converter dan knalpot dengan catalytic converter, pada tiga variasi putaran mesin (1600, 2500, dan 6000 rpm) dengan tiga kali pengulangan pada setiap kondisi. Emisi CO (%) dan HC (ppm) diukur menggunakan exhaust gas analyzer. Hasil menunjukkan bahwa pemasangan catalytic converter menurunkan rata-rata CO dari 5,16% menjadi 4,40% (1600 rpm), 0,93% menjadi 0,54% (2500 rpm), dan 0,51% menjadi 0,37% (6000 rpm). Rata-rata HC juga menurun dari 279 ppm menjadi 209 ppm (1600 rpm), 91 ppm menjadi 75 ppm (2500 rpm), dan 39 ppm menjadi 37 ppm (6000 rpm), dengan persentase penurunan rata-rata HC berturut-turut 25,08%, 17,58%, dan 5,12%. Temuan ini mengindikasikan bahwa catalytic converter berbahan stainless steel berpotensi menurunkan emisi CO dan HC pada konfigurasi pengujian yang digunakan. This study evaluates the effect of installing an aftermarket stainless-steel catalytic converter (Brand KR 49 Racing, 50 mm diameter) on carbon monoxide (CO) and hydrocarbon (HC) exhaust emissions of a 2014 Honda Beat FI KZL-series motorcycle. An experimental design was applied under two conditions: a standard exhaust without a catalytic converter and an exhaust equipped with the catalytic converter, tested at three engine speeds (1600, 2500, and 6000 rpm) with three repetitions per condition. CO (%) and HC (ppm) were measured using an exhaust gas analyzer. The results show that the catalytic converter reduced mean CO from 5.16% to 4.40% (1600 rpm), from 0.93% to 0.54% (2500 rpm), and from 0.51% to 0.37% (6000 rpm). Mean HC decreased from 279 ppm to 209 ppm (1600 rpm), from 91 ppm to 75 ppm (2500 rpm), and from 39 ppm to 37 ppm (6000 rpm), corresponding to mean HC reductions of 25.08%, 17.58%, and 5.12%, respectively. These findings indicate that a stainless-steel catalytic converter can reduce CO and HC emissions under the tested conditions.

Abstract

Stunting awareness campaigns conducted through the Community Service Program (Kuliah Kerja Nyata/KKN) serve as a strategic initiative to raise public awareness about the importance of balanced nutrition for child growth and development, considering that stunting resulting from chronic nutritional deficiencies can have long-term effects on children's physical and cognitive development. In this activity, students acted as agents of change by educating the community on healthy eating patterns, the importance of exclusive breastfeeding, and routine child growth monitoring. The outreach methods included counseling sessions, interactive discussions, demonstrations of nutritious food preparation, and social media campaigns to reach a broader audience. Challenges encountered included low public understanding and limited access to nutritious food. However, through participatory approaches and collaboration with healthcare professionals and local government, the activity successfully increased community awareness of the dangers of stunting and preventive measures. The implementation results showed a significant improvement in understanding the importance of family nutrition, with the potential to contribute to a reduction in stunting rates in the target area. This initiative not only produced short-term impacts but also fostered long-term awareness that supports healthy lifestyles within families. Therefore, stunting-focused KKN programs should continue to be developed and expanded to promote the emergence of a healthy and stunting-free generation.

Abstract

Abstract: The quality of vehicle body painting results is largely determined by the condition of the compressed air used during the spraying process. Compressor air containing water vapor can cause various surface defects such as blistering, pinholing, orange peel, and fisheye, which directly reduce the gloss level of the paint surface. This study aims to examine the effectiveness of using a water trap in the compressor air system on improving painting quality, measured through gloss values using a gloss meter. A quantitative experimental method was employed with two treatment groups: painting without a water trap and painting with a water trap, each tested three times. Results showed that the average gloss value without a water trap was 98 GU, while with a water trap it was 103.33 GU, representing an increase of 5.44%. An independent t-test revealed a significant difference (t = 7.99; Sig. = 0.001 0.05). It is concluded that the use of a water trap significantly improves painting quality by enhancing the atomization process through reduced moisture content in compressed air.Keywords: Water trap, Gloss meter, Painting, Compressor Air, Atomization.

Abstract

Abstract: The charging system is a vital component on motorcycles because it functions to supply electric current and recharge the battery. The 2014 Honda Supra X 125 motorcycle uses a halfwave charging system that only utilizes half the cycle of alternating current waves so that the charging current is relatively small and unstable, especially when overloaded with an LED lighting system that requires direct current. This study aims to compare the stability of current and battery voltage between halfwave and fullwave charging systems when using lighting loads, bulbs, and full LED lights. The study used an experimental quantitative approach with a pretest-posttest control group design, in which the standard charging system (halfwave) was modified to fullwave. The parameters measured include regulator voltage, battery voltage, State of Health (SOH), State of Charge (SOC), and ripple frequency at engine off and engine running conditions of 1,400 RPM. The results showed that the voltage of the fullwave regulator (13.04 V) was higher than that of the halfwave (10.84 V). In the condition of the engine running with full LED load, only the fullwave system experienced an increase in battery voltage by +1.40 V, while other combinations experienced a decrease. The SOH and SOC values in the fullwave system are more maintained, and the ripple frequency of the fullwave (maximum 45.70 Hz) is lower than that of the halfwave (maximum 84.70 Hz). It can be concluded that a fullwave charging system is more effective at maintaining current and voltage stability as well as battery life than halfwave.Keywords: Charging System, Halfwave, Fullwave, LED Light, Battery Life, Ripple
