Abstract

The increasing development and maintenance of pavement infrastructure result in increasing demand for materials to be used, including the fillers. The use of fillers in asphalt concrete mixtures is very limited in amount but contributes to considerable effects on the performance of the mixtures. A general problem faced in the production of fillers obtained from stone crushing is that it can only produce a substantially less volume than needed; hence the efforts to find alternative sources for fillers. Bagasse ashes are one of solid residual wastes produced as the byproduct of the process of sugar cane heating. This paper presents the results of laboratory works devoted to evaluating the use of bagasse ashes as fillers in a Superpave mixture. Laboratory tests were carried out in three stages. Firstly, physical property tests were run. Secondly, a series of optimum bitumen content for mixtures with 0%, 25%, 50%, 75%, and 100% of bagasse ashes portion to the total portion of fillers were determined respectively. Lastly, Marshall Characteristics were measured and immersion tests were conducted upon the mixtures. Results showed that, in general, sampled bagasse ashes were suitable as fillers for the Superpave mixture. The greater the percentage of bagasse ashes corrensponds to the lower values of stability, VITM, VMA, and the higher values of flow, VFWA, MQ and Index of Retained Strength. Higher proportion of bagasse ashes requires higher optimum bitumen content.

Abstract

Abstract Rain water is a liquid contains dissolved materials as well as acidic salts which may results in pavement damage. This paper presents the laboratory test results on the effect of the rain water immersion on Marshall characteristic and durability of Split Mastic Asphalt mixture using two types of binder, namely Starbit E-55 and AC 60/70. Initially, laboratory tests were conducted to find the optimum bitumen content based on Bina Marga (2010) standards. Then, the Marshall and immersion tests after various immersion on rain water were run. The results showed that the longer the rain water immersion, the lower stability, Marshall Quotient, and index of retained strength, but the higher the flow of the mixture. Specimen using Starbit E-55 was found having a better strength performance and durability due to rain water immersion than that of the mixture using conventional bitumen of AC 60/70. Keywords: rain water immersion, durability, Starbit E-55, and Split Mastic Asphalt  Abstrak Air hujan merupakan cairan yang mengandung bahan-bahan terlarut maupun garam-garam yang bersifat asam sehingga dapat menyebabkan gangguan kinerja dan dapat menyebabkan kerusakan perkerasan. Paper ini menyajikan hasil pengujian laboratorium tentang pengaruh rendaman air hujan terhadap karakteristik Marshall dan durabilitas campuran Split Mastic Asphalt, dengan menggunakan dua jenis aspal sebagai bahan ikatnya, yaitu aspal Starbit E-55 dan aspal AC 60/70.

Abstract

Toll roads are one of the infrastructure development targets in Indonesia to speed up traffic and vehicle travel times. This paper analyzes the flexible pavement structure of the Yogyakarta-Bawen Toll Road. It predicts damage and residual values using elastic and viscoelastic approaches based on MDPJ Bina Marga 2017 using the KENPAVE Program. The recommended design alternative is pavement with a layer of AC-WC 40 mm, AC-BC 60 mm, Base AC 180 mm, and LPA 300 mm. This alternative is predicted to be able to serve load repetitions in the elastic approach of 432,857,828 ESAL until fatigue cracking occurs, 215,176,089 ESAL until rutting occurs, and 136,575,580 ESAL until permanent deformation occurs. Analysis using the viscoelastic approach can provide load repetitions of 153,304,378 ESAL until fatigue cracking occurs, 47,014,109 ESAL until rutting occurs, and 71,859,938 ESAL until permanent deformation occurs. Based on the elastic approach, the pavement's service life is 33 years, with initial damage in the form of permanent deformation. In comparison, the viscoelastic approach has a service life of 22.7 years, with initial damage in the form of rutting.

Abstract

The Stone Matrix Asphalt (SMA) concrete mixture generally consists of aggregates, fillers, and additives. Stone dust filler has become a scarce component in the composition of the mix. One alternative filler that can be used is geothermal waste, which contributes to environmental pollution reduction and enhances its utility. This research investigates the influence of geothermal waste content as a substitute filler on the characteristics of Stone Matrix Asphalt (SMA) mixtures. The laboratory research follows the SNI 8129:2015, examining aggregate, filler, and asphalt materials. Subsequently, test specimens are fabricated to determine the optimum asphalt content (OAC). The OAC produces test specimens for Marshall, VCA, IRS, ITS, TSR, CL, and AFD tests. These tests are conducted at each geothermal waste filler substitution level, ranging from 0%, 10%, 20%, 30%, to 40%. The analysis results indicate that using geothermal waste as a filler in SMA mixtures performs optimally at a 40% substitution level. Increasing the substitution level enhances VFWA and density while decreasing VITM and VMA, as well as flow values. The SMA mixture achieves good stone-on-stone contact, demonstrated by the VCA value. As IRS and TSR indicate, geothermal waste improves stability and indirect tensile strength, enhancing the mixture's durability. Geothermal waste enhances the overall integration and homogeneity of the mix, making it resistant to plastic deformation and high temperatures, as observed in CL results.

Abstract

A pavement management system needs to be implemented as a form of road management to ensure that roads function properly. The Markov Chain model describes future pavement conditions to produce optimal highway maintenance. The research was carried out on Suprapto Street, Ahmad Yani Street, and Yos Sudarso Street in Indramayu Regency. Based on road conditions in 2024 by PCI and SDI assessment results, predictions are made by multiplying the initial condition vector by the transition probability matrix. Once the condition of the road is known, the proposed type of maintenance can be determined based on Ministerial Regulation of Public Work No. 13/PRT/M/2011, along with the costs required based on the maintenance cost history. The Markov Chain predictions show that road conditions will deteriorate and there will be an increase in severe damage over the years if no treatment is carried out. Maintenance action patterns vary; sections that experience a high level of damage will receive more serious treatment, and in the following year maintenance will decrease and then increase again according to the level of damage. The pattern of maintenance costs also follows the handling actions taken. Costs in the initial year were the highest, while most costs were spent on Suprapto Street.

Abstract

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. Based on Indonesian Health Survey (SKI) 2023, the prevalence of pulmonary tuberculosis according to doctors’ diagnosis reached 0.3% in Indonesia and 0.4% in DKI Jakarta. This study aims to determine effective communication strategies regarding TB control in the Puskesmas Setiabudi’s assisted area in 2024. We used a two group pre- and post-test design with 42 samples. They were divided into two groups and each group received education by using poster or video as medias. Knowledge data was obtained by filling out questionnaires and characteristic data through interviews. Results most of the cadres had secondary education level (84 and 76.5%) and the average age was above 50 years (55.28 and 50.71 years). There was a greater knowledge increase in the group that received education with audiovisual media (0.59) compared to the group that received education with poster (-0.80) after receiving the education. Conclusion is the utilization of audiovisual media in education is a more effective communication strategy in increasing cadre’s knowledge related to TB prevention and control in the Puskesmas Setiabudi’s assisted area in 2024. It is recommended to modify the refresher workshop method by using audiovisual media.
