Modified Asphalt Mix Performance with the Addition of Human Hair Waste

The development of road infrastructure in Indonesia is currently increasing, starting with new road construction projects to road improvement projects. To prevent premature damage to road pavements due to loading and the influence of water, it is to improve the quality of asphalt as a binder material from aggregate in the composition of road pavements. especially for the Asphalt Concrete-Binder Course (AC-BC) mixture, the addition of human hair waste can be used as an added material to minimize the use of asphalt and overcome the weaknesses of asphalt and waste utilization.The objectives of the study were: (1) to analyze the characteristics of the modified asphalt mixture with the addition of human hair waste. (2) Analyzing the performance of modified asphalt mixture with the addition of human hair waste.The results of analysis and testing in the laboratory show that the modified asphalt mixture performance with the addition of hair will increase the density value up to 2,355 gr/cc, increase the stability value up to 1886,2 kg, increase the value of the asphalt filled cavity (VFB) up to 82.8% and increase the Marshall value. Quotient (MQ) up to 653.3 kg/mm, but will reduce the value of the melt (flow) up to 2.9 mm, reduce the value of voids between mineral aggregates (VMA) up to 15.8% and reduce the value of mixed air voids (VIM) up to 2.7% but still within the threshold of meeting specification

Faktor-Faktor yang Mempengaruhi Mutu Pelaksanaan Proyek Peningkatan Jalan Tedubara-Pising Kabupaten Bombana

This study aims to analyze the factors that influence the quality of the implementation of improving the Tedubara-Pising street in Bombana Regency. This study uses quantitative data analysis techniques with a sample size of 30 respondents. The results showed that the factors affecting the quality of the Tedubara Pising road improvement in Bombana Regency were financial indicators (X3) 21.97%, followed by Human Resources indicators (X1) 20.14%, location indicators (X5) 19.68 %, material indicator (X2) 19.22%, and the lowest is equipment indicator (X4) 18.99%. Factors related to the quality of road improvement, namely the human resources variable with a value of 0.855 and material with a value of 0.853. This shows a very strong relationshi

Cost Analysis of Occupational Health and Safety (K3) on the Road Preservation (Case Study : Road in Kendari City – Kendari City Boundary)

The purpose of this study was to determine how much the application of K3 and to analyze the cost of K3 on the road preservation project within Kendari City - Kendari City boundary. The results showed that the level of use of PPE in road preservation work in the city of Kendari did not meet the standards for the level of use of PPE / included in the less category. This is because the average value of the level of use of PPE in road shoulder work, asphalt Ac-Wc and Talud is 60%. The cost required for the implementation of Occupational Safety and Health (K3) on the Road Preservation project. The required K3 cost based on the unit price of the regulation is IDR 266,645,950.00 or around 2.17%, while the cost based on field prices is IDR 257,953,950 or about 2.10%. The percentage of K3 costs at the regulation price is greater than the percentage of K3 costs at field prices with a difference of 0.07% or Rp. 8,692,000.00

Analisis Kinerja Alat Berat pada Proyek Normalisasi dan Perkuatan Tebing Sungai

The purpose of this study was to analyze the performance of heavy equipment and the duration of time required to complete the Windo River Cliff Normalization and Reinforcement Project, Pamandati Village, Laeya District, South Konawe Regency. The results showed that the excavator's performance in excavation work (mechanical) was 38.68 m3/hour, dump truck 2.99 m3/hour. As for the embankment work imported from outside, the performance of the excavator is 98.53 m3/hour and the dump truck is 3.05 m3/hour. Where the duration of time required to complete the excavation work (mechanical) with an excavator is 12 days and for embankment work imported from outside is 2 days.
