Abstract

Cases of carbon monoxide (CO) poisoning inside vehicles continue to occur and often result in fatalities. This study aimed to investigate the relationship between CO gas concentration and the ventilation conditions of a cabin replica to determine the most effective power window opening width for minimizing the risk of poisoning, as well as to implement the system in a power window trainer. The research method involved designing and developing a power window trainer based on an Arduino Nano microcontroller. Experimental tests were conducted to quantitatively analyze the effects of variations in CO gas concentration and the number of ventilation openings, each with a diameter of 32 mm, on the automatic window opening width. The collected data were then analyzed using the Taguchi method. The results showed that higher CO gas concentrations resulted in wider window openings, with the maximum opening width reaching 5.8 cm at a CO concentration of 25 ppm. The number of ventilation openings also affected system performance, with the best condition achieved using one ventilation opening when the CO concentration reached 25 ppm. In addition, the fastest window-closing response was obtained when two ventilation openings were used at a CO concentration of 25 ppm

Abstract

Delays or failures in airbag system activation can have fatal consequences for driver safety, thus requiring a collision detection mechanism with a high degree of precision and reliability. This study aims to design and evaluate an experimental testbed to analyze the characteristics of impact acceleration as the primary trigger parameter in airbag activation systems. The collision dynamics simulation was represented through the implementation of the sled test method using a data acquisition system that integrates an ADXL345 accelerometer, which had undergone precision validation via a six-position tumble test on 100 reference samples, and an FC-51 infrared sensor specifically calibrated for measuring the distance and velocity of objects. Based on vehicle dynamics literature, which refers to a deceleration range of 3g to 5g at speeds of 16–24 km/h, the threshold configuration for actuation is set at an acceleration of 40 to 46 m/s². The results of the instrumentation performance tests showed good data reading stability, with an average sensor noise fluctuation level of 3.5 m/s². A comparative statistical analysis using a two-sample t-test on two impact velocity variations demonstrated a mathematically highly significant difference in acceleration, with a p-value = 0.000. The airbag simulation developed demonstrates a high level of reliability in precisely identifying impact forces in accordance with threshold parameters. This study concludes that experimental methods are highly effective for characterizing airbag activation trigger parameters, but further research is needed to comprehensively evaluate airbag response performance.

Abstract

The Kelompok Wanita Tani (KWT) Mandiri in Mojorejo Hamlet, Batu City, manages Nile tilapia biofloc culture and vegetable production in a greenhouse, but water delivery had relied on a manually moved hose. This community service program aimed to install an integrated water supply system linking a storage tank, booster pump, main pipeline, biofloc pond outlet, and greenhouse distribution line. The activity used technical assistance and technology transfer through field observation, hydraulic design, component selection, pipe fabrication, installation, functional testing, and operational guidance. The installed system successfully conveyed water from the storage tank through the pump and pipeline to the biofloc pond outlet, while the greenhouse distribution line was arranged along the planting beds. Visual testing showed a continuous water flow and confirmed the functional connection among the main components. The system simplified pond filling, organized the distribution network, and reduced the need to move hoses repeatedly. However, performance evaluation remained qualitative because pressure, discharge, head loss, and irrigation uniformity were not measured using gauges or flow meters. Therefore, follow-up monitoring is required to quantify hydraulic performance and optimize irrigation scheduling. The program demonstrates that a simple, maintainable water-supply network can support more practical management of integrated aquaculture and greenhouse activities at the community level.
