RANCANG BANGUN DAN EVALUASI KINERJA SIMULATOR SISTEM PENDINGIN ENGINE TERHADAP TIGA JENIS CAIRAN PENDINGIN
No full textThis study aims to design and develop a simulator of an automotive engine cooling system that serves both as a practical learning tool and an experimental platform to evaluate the effectiveness of three types of coolant fluids: radiator coolant, mineral water, and demineralized water. The simulator was built using an Arduino-based system equipped with temperature sensors, a heating element, a water pump, and a radiator fan. The experiment focused on three key indicators: the time needed to reach engine operating temperature, the temperature difference between radiator inlet and outlet (ΔT). Results showed that mineral and demineralized water outperformed radiator coolant in terms of thermal efficiency, particularly in heat transfer rate and temperature drop. Beyond numerical results, the simulator also enabled learners to directly observe coolant flow and the function of each component, enhancing their conceptual understanding. This study contributes to the development of accessible, practice-based automotive learning media, while also offering experimental insight into alternative coolant fluids in the context of vocational education.

PID Control System for Shaking Table and Bearing Capacity Measurement on Soil Liquefaction Simulator
Get PDFLiquefaction occurs when soil that was previously stable and solid suddenly loses its strength and stiffness within a short period. This research develops a model for testing soil liquefaction using a 1-g shaking table. The system, based on LabVIEW, is designed to measure and analyze the performance of foundations during soil liquefaction tests. It enables the evaluation of soil characteristics before, during, and after an earthquake that could induce liquefaction, while also considering foundation reinforcement. In this study, the Ziegler-Nichols PID tuning method was employed to improve control accuracy and stability during seismic vibration simulations and to measure soil bearing capacity. The results indicate that the system achieved a rise time of 8 seconds, a delay time of 13 seconds, an overshoot of 0.06%, a settling time of 13 seconds, and a steady-state error of 0.02%. Compared to the Trial Error method, the Ziegler-Nichols method achieves faster rise time, delay time, and settling time but results in higher overshoot and steady-state error. The sensor data provides detailed information about the helical pile's ability to support vertical loads, with an average bearing capacity of 3.99 kPa

PHYSICAL ACTIVITY OF ELEMENTARY SCHOOL STUDENTS IN URBAN AREAS POST COVID-19 PANDEMIC
Get PDFThe peri-urban area is an area located on the outskirts, so that students' physical activity can still be found in various places. However, the current view is different after the Covid-19 pandemic, currently students tend to do very minimal physical activity. In addition to the loss of interest in doing physical activity due to the closure of all public facilities, the impact of gadget addiction for elementary school students affects the management of students' emotional processing. This study aims to (1) examine the physical activity of elementary school students in the peri-urban area, (2) determine the physical activity of students after Covid-19 in the peri-urban area, and (3) reveal the factors that influence the physical activity of students in the peri-urban area. This study is descriptive quantitative. The population used in public elementary schools in the suburbs was 169 students. The sampling technique for this study was taken using the simple random sampling technique. The physical activity measurement instrument in this study used the Physical Activity Questionnaire–Children (PAQ-C). Data analysis used descriptive statistics expressed in the form of percentages. The results of the study showed that the physical activity of students in the peri-urban area showed that 82 students (48.52%) had good activity conditions. Meanwhile, as many as 87 students (51.47%) had poor physical activity conditions. This provides a real picture that the Covid pandemic that occurred can reduce the physical activity conditions of elementary school students. Then the physical activities that are widely carried out by students in peri-urban areas include football, walking, cycling, jogging, futsal and other physical activities. Students' physical activity after the pandemic is influenced by the Covid disaster management policy with social restrictions, changes in sedentary lifestyles during online learning activities, technological advances that cause students to prefer games that use less physical activity and the lifestyle of students' parents. The conclusion of this study is that the Covid-19 pandemic has an effect on students' physical activity which is correlated with the health conditions of students in peri-urban areas
