Abstract

Reconstruction of the road section uses the flexible pavement method where aggregate material is the main component of the structure. Choosing the right aggregate gradation and meeting the specification requirements will greatly determine the quality of the road. This research aims to determine the characteristics of aggregate gradation sourced from stock files and compare the results of aggregate gradation analysis of job mix design planning consultants. The method uses laboratory testing. Aggregate wear test results 2-3 = 5.36%, 1-2 = 6.14%. The absorption value of aggregate 2-3 = 0.87%, 1-2 = 1.79%, 0.5 - 1 = 1.80% and stone ash = 2.27%. Values of dry specific gravity, SSD specific gravity, and apparent specific gravity of aggregate 2-3 = 2.73, 2.69, 2.66, 1-2 = 2.72, 2.64, 2.62 0.5- 1 = 2.70, 2.62, 2.58, rock ash = 2, 53, 2.59, 2.69. These values meet the requirements of the 2018 Bina Marga specifications, 2nd revision. The comparison of the results of the field aggregate gradation test analysis with the results of the job mix design analysis is the same because the aggregates tested come from the same stock file. The results of the sieve analysis test showed that the coarse aggregate fineness modulus of 2-3, 1-2, and 0.5 - 1 did not meet the specification standards, while the fine aggregate for stone ash did. The value that does not meet is caused by not paying attention to the additional note that the coarse aggregate retained on the 1" sieve is ±6%.

Abstract

PT. Eastern Pearl Flour Mills – City Side Makassar affects land use changes that have an impact on changes in traffic movement, so traffic impacts analysis is needed. The purpose of this study is to identify the performance of affected roads and intersections in the present and in the next 5 years, to handle traffic problems and conflicts by simulating models without handling (Do Nothing) and with handling (Do Something), analyzing time delays on the U-turns and modeling the origin-destination matrix using the Furness Method. This study uses qualitative and quantitative analysis methods that refer to the Manual Kapasitas Jalan Indonesia (MKJI, 1997) and The Furness method. The results of the analysis of the level of service on the Jl. The archipelago is in fairly good condition with LoS values A to B and DS 0.11 – 0.40 with a speed of 26.60 – 50.00 km/hour, the road performance that has the worst impact occurs at the Tol Reformasi – Jl. Nusantara with a projection for the next 5 years in 2027, where road performance has a LoS E and DS value of 0.88 with a delay time of 19 seconds/pcu. U-turn facility on Jl. Nusantara has an average delay time of 6.16 – 7.82 seconds for one rotating vehicle with a value of < 1 so that there is no queue. The results of the trip distribution analysis using The Furness model obtained the same value of generation and attraction in the second iteration, which means that it is still close to ideal conditions.

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.
