Abstract

This study aims to analyze the effect of variations in bi-LED projector power and the use of a voltage stabilizer on the luminous flux on a motorcycle. The luminous flux produced by a motorcycle lighting system plays a very important role in improving rider visibility and safety, especially at night. Therefore, this study uses a quantitative experimental method with a two-way factorial approach (Two-Way ANOVA) to test the effect of two main variables, namely the bi-LED projector power and the voltage stabilizer configuration. The power variables tested include three power levels, namely 35 W, 70 W, and 105 W, while the voltage stabilizer configuration includes three conditions, namely without a stabilizer, 14 V, and 14.5 V. Luminous flux measurements were carried out using a lux meter at a distance of five meters from the reflective surface, and the results were then combined into lumen units to facilitate comparison between power variations and stabilizers. The results showed that increasing the bi-LED projector power significantly increased the luminous flux produced. The 105 W power output produced the highest luminous flux, reaching 42,319 lumens when combined with a 14.5 V voltage stabilizer. This demonstrates that the combination of high power and proper voltage stabilizer use can improve the quality of motorcycle lighting. The very low P-value (0.000) and R² of 100% indicate that the predictive model used in this study is robust and reliable. Overall, this study emphasizes the importance of using a voltage stabilizer in motorcycle lighting systems. A voltage stabilizer is not only a complementary device but also a crucial component for improving visibility and driving safety, especially at night. Therefore, proper use of a stabilizer can improve lighting performance and provide significant safety benefits.

Abstract

The use of fossil-fueled vehicles has long been a major cause of exhaust emissions that pollute the air and exacerbate global climate change. In an effort to address this problem, Indonesia has begun developing electric vehicles as a more environmentally friendly alternative solution. Electric vehicles (EVs) are considered capable of reducing dependence on fossil fuels while simultaneously reducing air pollution levels. The Indonesian government has demonstrated its commitment to supporting electric vehicle development by issuing several strategic policies, including Presidential Regulation (Perpres) Number 55 of 2019 concerning the Acceleration of the Battery-Based Electric Motor Vehicle Program for Road Transportation, and Presidential Instruction (Inpres) Number 7 of 2022 concerning the Use of Battery-Based Electric Motor Vehicles as official vehicles for central and regional government agencies. In line with these policies, research was conducted to assess the power consumption efficiency of the Ken Dedes electric vehicle prototype, designed using a 250-watt DC motor and a mid-drive system. The main focus of this research was to analyze the effect of variations in module input voltage and gear size on the vehicle's power consumption level. The method used was an experimental approach with a quantitative approach, where a series of tests were conducted on several gear combinations and input voltage levels. The results of the study indicate that variations in these two parameters—gear size and input voltage—significantly affect motor power consumption. The most optimal combination in this study achieved a power consumption efficiency of 6 Wh/km. This figure demonstrates the most energy-efficient performance in vehicle operation and can serve as a benchmark for further development of similar electric vehicles. This research provides an important contribution to efforts to encourage the use of more efficient and sustainable electric vehicles in Indonesia.

Abstract

Consistent and efficient concrete quality in each implementation is one of the main factors in the success of construction projects. Concrete as a structural material requires strict quality control in order to meet the technical standards that have been set. One way to improve the quality of concrete is to add certain additives to the job mix formula (JMF). This research is focused on the application of SG type additives known as chemical-based additives to improve the properties of fresh concrete and hard concrete. SG additives have an important function in increasing workability, speeding up or slowing down the binding time as needed, maintaining quality stability, and strengthening concrete finishes. In this study, a comparison was made between a concrete mixture with SG additives and a concrete mixture without additives. The tests included slump parameters, initial binding time, and compressive strength at 7 and 28 days of age. The test results showed a significant difference, especially in the improvement of the consistency and compressive strength of concrete with the use of additives. The results of the discussion showed a comparison of Trial Mix 1 and Trial Mix 2 that are different in terms of material composition, cost efficiency, and compressive strength of concrete. Trial Mix 2 with the composition of cement, admixture, water, and aggregate (sand and split) showed more optimal results. The compressive strength achieved was 821,396.00 kg/cm² at the age of 28 days. In terms of cost, Trial Mix 2 requires Rp. 351,582.00 per m³, with an efficiency difference of around Rp. 32,953.00 per m³ compared to the previous mix

Motorcycles, which initially served only as a practical means of transportation, have now evolved into a lifestyle element and a popular activity among many communities. Along with the increasing demand from consumers for performance and efficiency, the development of transmission technology, particularly the Continuously Variable Transmission (CVT) system, has become an important aspect that requires serious attention. One of the key components in the CVT system is the double clutch lining and the clutch housing, which play a vital role in transferring torque and power from the engine to the driving wheel. The performance of these components directly affects acceleration, efficiency, and engine durability. Therefore, research on the design and modification patterns of the double clutch lining and clutch housing is essential to determine an optimal configuration. This study applies an experimental method using a 110 cc motorcycle as the test object. Several modification patterns were applied to the double clutch lining and clutch housing to examine their influence on vehicle performance. The testing process was carried out using a dynotest, which enables precise measurement of torque and power across different engine speeds. The data obtained from these tests are expected to provide a clear overview of the effect of modification patterns on the transmission performance of motorcycles. The findings of this research are expected to contribute significantly to the development of more efficient and optimal designs for double clutch linings and clutch housings. Furthermore, this study may serve as a valuable reference for the automotive industry as well as motorcycle modification communities in enhancing vehicle performance while maintaining efficiency and component durability.

Abstract

. The phenomenon of a potential megathrust earthquake predicted to occur in the coming years has raised widespread concern among the Indonesian public, particularly due to the high vulnerability of existing structures. In response to this issue, this study aims to analyze the structural capacity of buildings in resisting seismic forces and lateral loads, with a specific focus on factory structures. As a civil engineering student specializing in structural engineering, the objective of this research is to examine the behavior, performance, and potential failure patterns of building structures under earthquake loads. The research method employs pushover analysis as a tool for structural assessment, while the evaluation process refers to the guidelines outlined in ATC-40. The analysis results indicate that the factory structure is capable of withstanding a lateral load of 108,587.40 kN, with a controlled roof displacement of 1.5 meters. The structural performance level is categorized under the Damage Control (DO) stage, specifically at performance level SP-2, where the structure remains standing under lateral loads but experiences damage requiring repair before reuse. Furthermore, the failure patterns observed reveal a progressive performance of structural elements, shifting from condition B (Basic), IO (Immediate Occupancy), LS (Life Safety), C (Collapse Prevention), up to E (Extreme Damage). These findings highlight the importance of proper structural design and evaluation in enhancing resilience, ensuring safety, and minimizing potential risks from future megathrust earthquake events.

Abstract

Welding is one of the most essential metal joining processes in manufacturing, construction, and industrial applications, where Shielded Metal Arc Welding (SMAW) remains widely used due to its flexibility, cost-effectiveness, and ability to be applied in various welding positions. This study aims to analyze the effect of welding position variations on the mechanical properties of SS400 steel, particularly in terms of tensile strength, bending strength, and microstructural characteristics. The experimental method was conducted using 6 mm thick SS400 steel with E6013 electrodes of 2.6 mm diameter in three welding positions: 1G, 2G, and 3G. The welded specimens were then tested through tensile testing (ASTM E8) and bending testing (ASTM E190-14), followed by microstructural analysis in the weld metal area. The results revealed that welding position significantly affects the mechanical properties of welded joints, where the 3G position produced the highest tensile strength of 188.48 kgf/mm², while the 2G position produced the lowest tensile strength of 113.70 kgf/mm². Conversely, the bending test showed that the 2G position provided the maximum bending strength of 1394 kgf/mm², followed by 3G and 1G positions. Microstructural observations demonstrated variations in the distribution of ferrite, pearlite, martensite, and cementite phases across different welding positions, with the dominance of ferrite and pearlite in the 3G specimen contributing to higher tensile strength, while the dominance of martensite and cementite in the 2G specimen enhanced hardness and bending resistance. Overall, this study confirms that welding position plays a crucial role in determining the quality of SS400 welded joints, and the findings are expected to serve as practical guidance for industry in selecting appropriate welding positions for construction needs, while encouraging further research with additional variables such as electrode type, welding current, and post-weld heat treatment to achieve a more comprehensive understanding.
