Abstract

This study investigates the impact of road gradient on fuel consumption, fuel rate (FR), and CO₂ emissions in freight transport vehicles with two-axle and three-axle configurations. The research was conducted on a 250-meter road segment with a 0.067 rad (~7%) gradient in front of Taman Rekreasi Datae, Sidenreng Rappang Regency, South Sulawesi, Indonesia. A quantitative mathematical model, based on vehicle technical parameters and empirical formulations from previous studies, was applied. Results show that increasing the gradient from 0 to 0.067 rad raised fuel consumption in two-axle trucks from 0.0356 L to 0.0857 L and in three-axle trucks from 0.1463 L to 0.3269 L. The FR for two-axle trucks increased from 0.0014 L/s to 0.0056 L/s, while for three-axle trucks it rose from 0.0033 L/s to 0.0124 L/s. CO₂ emissions from two-axle trucks increased from 0.0958 kg to 0.3941 kg, and from 0.2310 kg to 0.8807 kg for three-axle trucks. The relative increase was higher for two-axle trucks (311%) than for three-axle trucks (281%), due to axle load distribution, engine capacity, and transmission ratio. These findings highlight the need to consider vehicle configuration and topography in route planning to minimize fuel consumption and emissions in hilly regions.

Abstract

Transportation and logistics are strategic aspects in goods distribution, where loading and unloading activities in warehouse areas are key factors determining operational efficiency. Parepare City, as a regional logistics hub in South Sulawesi, still faces challenges such as limited facilities and long truck waiting times due to ineffective loading and unloading scheduling. This study aims to analyze warehouse characteristics, transportation modes, and measure the influence of the quantity of goods (X1), equipment and labor performance (X2), and loading and unloading time (X3) on productivity and effectiveness (Y). The method used is a descriptive quantitative approach through field observations, questionnaires, and documentation studies, with multiple linear regression analysis using SPSS version 27. The study covered six warehouses, consisting of three commercial warehouses, a steel material warehouse using forklifts, a fertilizer warehouse, and a rice warehouse using manual labor. The results show performance disparities, where the steel material warehouse using forklifts recorded the highest productivity of 51 pieces/minute with an R² value of 79.5 percent, while the rice warehouse only reached 8 sacks/minute. Simultaneous (F) and partial (t) tests confirmed that X1, X2, and X3 significantly influence Y. These findings emphasize that optimizing forklift utilization, improving labor competency, and improving loading and unloading scheduling are key factors in increasing logistics efficiency in the Parepare warehouse area.

Abstract

Exhaust emissions from motor vehicles, especially freight transportation, are one of the main causes of air pollution in cities. This research aims to develop a portable and low-cost microcontroller-based vehicle emission measurement system. The system uses Arduino Uno with MQ-7 and MQ-2 sensors to detect carbon monoxide (CO) and hydrocarbons (HC) concentrations in real-time, with the measurement results displayed on the liquid crystal displays (LCD) screen. Validation is carried out by comparing the measurement results of the tool with a calibrated gas analyzer as a standard tool. The test results showed an error rate of 0.29%–1.79% for CO and 1.85%–3.84% for HC, as well as sensor stability after about 360 seconds of heating. With its compact design, easy to operate, and low cost, this system has the potential to be an alternative vehicle emission monitoring tool for field inspection and testing activities at vehicle workshops.

Abstract

Asbuton is a promising local material that can partially replace petroleum asphalt in AC-WC hot mix asphalt. This study aims to investigate the influence of varying Asbuton B50/30 content on the performance of asphalt mixtures using the Marshall method. The optimum asphalt content (OAC) was determined to be 6.29%, followed by testing with Asbuton contents of 7%, 9%, and 11% of the total asphalt weight. The evaluated parameters included stability, flow, Marshall Quotient (MQ), and volumetric properties (VIM, VMA, and VFB), all assessed against Bina Marga technical specifications. The results indicate that 7% Asbuton content provides the best performance, yielding the highest stability (1977.70 kg) and MQ (632.35 kg/mm), while maintaining volumetric parameters within specification limits. At higher Asbuton contents (9% and 11%), stability and MQ declined, whereas flow and VFB increased, suggesting an over-binder effect that reduces structural integrity. These findings highlight the importance of proper Asbuton dosage control to balance mechanical and volumetric properties. This study contributes to the advancement of knowledge in asphalt pavement engineering by emphasizing the dual role of Asbuton as both a filler and a binder modifier, while also providing a scientific basis for utilizing local materials to support more sustainable pavement development.

Abstract

The growth of road infrastructure in Indonesia encourages the use of more efficient and sustainable pavement materials. This study aims to evaluate the effect of partial substitution of asphalt with low-grade Asbuton B5/20 (2–4%) on the mechanical performance of AC-WC mixtures. Testing was conducted using the Marshall method with parameters of stability, flow, Marshall Quotient (MQ), VIM, VMA, and VFB, and referring to the General Specifications of Bina Marga 2018 Revision 2. The results show that the addition of 2% Asbuton yields optimal performance with an MQ value of 366.18 kg/mm and all volumetric parameters meeting the specifications. An addition above 2% causes a decrease in stability and stiffness, although it's still within standard limits. These findings indicate that Asbuton B5/20 can be used as a partial substitute for asphalt binder at an optimum content of 2%, supporting the efficiency of local materials for tropical road pavements. Further studies are recommended to test the field performance and long-term durability of the mixture.
