This study aimed to better understand how factors like price, taste, and location affect how much consumers want to buy Elo Pia Kediri products. The research used a quantitative method because it helps collect objective and measurable information that can be analyzed using statistics to make clear conclusions. The data came from two main places: primary and secondary sources. Primary data was gathered directly from consumers through questionnaires that asked about price, taste, location, and how much they wanted to buy the product. Secondary data was collected from books, articles, and other documents related to the topic. The study included all consumers who had bought Elo Pia Kediri products. However, since the total number of people wasn’t known and was quite large, the researcher selected a representative group. The sample size was 96 people. The method used to choose participants was accidental sampling, which means people were selected randomly or by chance as they were met at the research location and agreed to take part. The results showed that price has a big effect on how much consumers want to buy the product. This means the prices set by Elo Pia Kediri match what consumers can afford and what they think is fair, which helps them decide to buy. When prices are seen as fair, affordable, and matching the quality of the product, it encourages people to make purchases. Taste also strongly influences buying interest. When a product has a tasty and unique flavor that fits what people like, it makes them interested in buying it. Taste is an emotional factor that affects how happy consumers are with the product and makes them want to buy it again. Location also plays a big role in how much people want to buy. A location that is easy to reach and close to where people usually go out makes it easier for them to buy Elo Pia Kediri products. The F test showed that together, price, taste, and location all have a significant impact on how much consumers want to buy the product.  

This study aims to determine the influence of local Bugis cultural values specifically Lempu (honesty and integrity), Temmappasilaingeng (impartial justice), and service quality on customer loyalty through satisfaction in laundry businesses in Watampone. A quantitative approach was employed using Partial Least Square Structural Equation Modeling (PLS-SEM) through SmartPLS 4, involving 120 respondents from three major sub-districts in Bone Regency. The results reveal that Lempu culture does not have a significant effect on customer satisfaction (T = 1.498; p = 0.137) or loyalty (T = 0.542; p = 0.589). Similarly, Temmappasilaingeng does not significantly influence satisfaction (T = 0.746; p = 0.457) or loyalty (T = 1.347; p = 0.180). Service quality, however, significantly affects customer satisfaction (T = 4.984; p = 0.000), but does not directly influence loyalty (T = 0.915; p = 0.362). Meanwhile, customer satisfaction significantly impacts loyalty (T = 2.760; p = 0.007). Mediation analysis also shows that customer satisfaction significantly mediates the relationship between service quality and loyalty (T = 2.437; p = 0.016), but not between Lempu (T = 1.318; p = 0.190) or Temmappasilaingeng (T = 0.702; p = 0.484) and loyalty. In conclusion, customer satisfaction is a key factor in building loyalty, and service quality is the dominant factor driving that satisfaction. Although local culture holds essential moral values, its influence on loyalty needs to be realized in the form of tangible service experiences to be directly felt by customers.

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. In this regard, innovations in CVT components hold great potential to support the advancement of two-wheeled transportation technology in the future.

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

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.

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.

This research examines the phenomenon of Gado-Gado Boplo as a legendary eating place recognized by Kompas, Flokq, and Nibble articles. The research uses quantitative methods using questionnaires via Google Form and secondary data from the internet, journals and interviews. The sample used was 100 people who had eaten at Gado-Gado Boplo using a Likert scale. All questions were declared valid, with a calculated R value > R table, after which the data was evaluated using Cronbach's alpha for reliability and Pearson Correlation for validity. Apart from that, the Cronbach alpha data value > 0.6 shows its reliability. The data was then subjected to multiple regression analysis, classical assumption testing, and hypothesis testing (T and F tests). The Excellence variable (X3) has a partially significant influence on the Purchasing Decision variable (Y), but the Strength (X1) and Uniqueness variables (X2) do not have a partial influence on the Purchasing Decision variable (Y), according to the T test. Furthermore, jji F shows that variables X1, X2, and X3 all influence Y significantly at the same time. In conclusion, superiority has a favorable and large influence on purchasing choices, but strength and uniqueness only have a small influence. These three X factors all have a significant influence on purchasing choices (Y) at the same time.

This study aims to analyze the effect of the combination of oil viscosity and shock load on the compression characteristics of telescopic shock absorbers on motorcycles, which include depth, time, and compression speed parameters. The experiment was carried out using two levels of oil viscosity, namely 10 cSt and 15 cSt (equivalent to SAE 10W and SAE 15W), as well as two shock load variations, namely 40 kg and 50 kg, which were dropped vertically from a height of 30 cm. Compression depth measurements were carried out using a slow-motion camera at a speed of 240 fps and the results were validated using Kinovea software. Meanwhile, the compression time measurement is carried out with a stopwatch, and the compression speed is calculated from the results of the comparison between the compression depth and the compression time. The experimental data were analyzed using Minitab software with the Two-Way ANOVA method to determine the influence of each variable on response. The results of the analysis showed that oil viscosity and shock load had a significant influence on the compression depth, while the viscosity of the oil also significantly affected the compression speed. However, neither the viscosity of the oil nor the shock load exerted a significant influence on the compression time. To support the results of the experiment, a mass-spring-damper system theory model approach was used, which represents the dynamic behavior of shock absorbers. This model helps to explain the compression response to changes in fluid and load parameters theoretically. Based on the analysis of experimental results and model simulations, the optimal combination that provides the best performance is found in the use of oil viscosity of 10 cSt (SAE 10W) with a shock load of 50 kg.

Disc discs are the main component in a motorcycle braking system that functions to convert kinetic energy into heat energy through friction. The geometric design of the disc, including the diameter and number of holes, affects the effectiveness of braking as well as the heat dissipation ability. This study aims to analyze the effect of variations in diameter and number of holes on disc discs on braking distance and disc temperature. The research method used was an experimental method with three variations in disc diameter (190 mm, 220 mm, and 260 mm) and three variations in the number of holes (30, 36, and 42 holes). The test was carried out through a controlled braking procedure at an initial speed of 40 km/h on flat road surfaces with stable weather conditions. Braking distance data is measured using ultrasonic sensors, while disc temperature is recorded with a high-accuracy infrared thermometer. The results showed that the diameter of the disc disc had the most significant influence on the braking distance. The larger the diameter, the greater the braking moment resulting so that the stopping distance becomes shorter. The number of holes in the disc also plays a role in heat dissipation because the holes enlarge the heat dissipation area. However, the increase in the number of holes tends to slightly increase the braking distance due to a reduction in the area of frictional contact field. The most optimal configuration is found on a 260 mm diameter disc with 42 holes, which results in the shortest braking distance of 8.25 meters and the lowest temperature rise of 4.47°C.  Statistical analysis using Two-Way ANOVA confirmed that the diameter and number of holes had a significant effect individually, but there was no significant interaction between the two. These findings confirm that the selection of the right disc dimensions is critical to improving braking performance, thermal efficiency, and rider safety.
