Technological advances in motorized transportation are progressing rapidly, making motorized vehicles the main mode of transportation. The increasing number of motorized vehicles in society results in a significant increase in exhaust emissions. Combustion in vehicle engines is not always perfect, producing exhaust gases containing compounds harmful to human health, such as carbon monoxide (CO), hydrocarbons (HC), carbon dioxide (CO2), and nitrogen oxides (NOx). This study investigates the effect of variations in piston dome shape on exhaust emissions in a 100cc internal combustion engine using RON 90 fuel. The goal is to find the optimal compression ratio to produce cleaner exhaust emissions. The research data are presented in tabular form and analyzed using one-way ANOVA and graphs. The results showed a significant reduction in CO and HC emissions at all engine speeds (1000, 2000, 4000, and 5000 rpm) with variations in piston dome shape. The reduction in CO emissions ranged from 55.07% to 85.73%, while the reduction in HC emissions ranged from 54.14% to 86.10%. These results suggest that variations in piston dome shape can be an effective solution to minimize harmful exhaust emissions in internal combustion engines.

This study aims to analyze the importance of applying professional ethics in civil engineering for decision-making related to safety, health, and environmental risks (K3L). This is crucial because, like other professions, civil engineering is a complex and intricate field that requires not only engineers with good technical skills but also sound decision-making abilities. The decision-making process significantly impacts the execution of infrastructure projects. Professional ethics serve as a guideline for engineers in making decisions that consider K3L. The issue is that decision-making is not solely based on technical skills but also on other soft skills such as emotional control. This study found that emotional intelligence (EQ) can influence the decision-making process of engineers. The higher an engineer's emotional intelligence, the better their decision-making regarding K3L risks. This is also related to engineers adhering to the professional code of ethics. Furthermore, good decision-making processes are expected to promote sustainable infrastructure development.

The use of motorcycles on unstable roads, such as off-road and potholes, demands the importance of a reliable suspension system for riding comfort and safety. Conventional testing of s is often ineffective in accuracy and data recording, so this research proposes the use of an automatic measuring instrument to improve test efficiency and accuracy, allowing users to evaluate  deflection in real-time and determine the optimal comfort level. The purpose of this research is to determine the effect of load and brand of motorcycle  on deflection value and deflection time. The research method used in this study is the experimental method, which involves a series of trials to collect empirical data related to the characteristics of the . This study uses independent variables in the form of load weight (60 kg, 80 kg, 100 kg) and  brand (Aspira, Showa, Kayaba). The measured dependent variables include deflection (mm) and deflection time (s) to evaluate the performance. The results showed that load and  brand had a significant effect on deflection and deflection time. Increasing load caused deflection to increase, with Aspira showing deflection of 40-42 mm at 60 kg load and 36-38 mm at 100 kg load. Kayaba had a shorter deflection time of 178.45–180.95 seconds at 100 kg load, compared to Showa's 245.45-275.75 seconds. This shows that Kayaba is more responsive in managing loads, with lower deflection and shorter deflection times than other brands, making it a more effective choice for dealing with varied road conditions.

Published: September 2024

This study aims to compare the energy efficiency between the use of a heater band and an infrared heater on an injection molding machine type borche bi 320T. The injection molding machine is one of the main pieces of equipment in the manufacturing process of plastic products and plays an important role in shaping various consumer and industrial products. One of the critical aspects of the operation of injection molding machines is the significant energy consumption, especially related to heating. This study was conducted by measuring the energy consumption of both types of heaters under the same operational conditions. The results showed that the energy consumption of using a band heater was 46.9 kW, while the infrared heater was 38.9 kW, significantly more energy efficient by 17.1% compared to the band heater. Although the initial installation cost of the infrared heater is 87% higher than that of the band heater, the energy savings generated from the infrared heater can reduce operating costs by approximately $39 million per year. Higher energy efficiency means lower electricity costs and, thus, more efficient total production costs. The use of infrared heaters also has a positive impact on the environment. Reduced energy consumption means reduced greenhouse gas emissions from power generation. Therefore, besides the economic benefits, the use of infrared heaters is also in line with sustainability and environmentally friendly practices.

PT X produces bottles using extrusion blow molding machines that produce EL 125-ml bottles of polypropylene borealis material. In the production process, there is a process of cutting the remaining material at the mouth of the bottle, called abfal. The separation of the abfal from the bottle mouth is still done manually by the operator before the product enters the quality control camera area. This research is experimental, comparing the pressure parameters and blow pin time with the thickness of the abfal mouth using an optical profile projector measuring instrument. In the variation of pressure parameters to the thickness of the abfal mouth, the thinnest occurred in the variation of blow pin pressure fast 80 kg/cm² and blow pin pressure slow 70 kg/cm² by 0.085 mm, and the size of the thickest abfal mouth occurred in the variation of blow pin pressure fast 60 kg/cm² and blow pin pressure slow 50 kg/cm² by 0.195 mm. In the variation of time parameters to the thickness of the abfal mouth, the thinnest occurred at a blow pin time of 1.4s by 0.085 mm, and the size of the thickest abfal mouth occurred at a blow pin time of 1.2s amounting to 0.195 mm. The results showed that the thickness of the abfal mouth is thinner if the pressure and time of the blow pin are given greater, and vice versa, if the pressure and time of the blow pin are given smaller, then the size of the abfal mouth is thicker
