Abstract

On national roads (arterial roads) whose LHR conditions should be the same or tend to be higher than provincial roads (collector roads) still often use slurry seals for handling to protect the asphalt layer from disintegration, cracking and reduced skid factor on the road. In fact, in its implementation on provincial roads, the lifespan of spot leveling works tends to have a much longer service life than slurry seals which tend to be damaged during the same fiscal year. This is certainly a contradictory conclusion between the two methods applied, namely on provincial roads with LHR tend to be lower than national roads using spot leveling treatment which has a longer lifespan, while on national roads it is the other way around. With the above problems, it is necessary to do further research on the factors that underlie the selection of the method, the service life of the results of the handling is compared to the construction costs incurred. The research method was carried out using LHR data to determine the condition of traffic loads on each segment of the segment, survey road conditions to determine the percentage of damage and the remaining service life of slurry seals and spot leveling, and compared with construction costs. The CESA value or traffic load characteristics affect the service life of the slurry seal, with a service life gap of 2.08 years and handling cost of Rp. 12,949.29 per square meter per year. Drainage conditions also influence the service life of the slurry seal, with a service life gap of 1.32 years and handling cost of Rp. 8,097 per square meter per year. Sidewalk conditions impact the service life of the slurry seal as well, with a service life gap of 0.52 years and handling cost of Rp. 4,688.39 per square meter per year. Based on the data on the service life gaps and handling costs, the most influential factor on the service life and duration of the slurry seal is the CESA condition on the road segment where the slurry seal is applied.

Abstract

The Kediri-Tulungagung Toll Road is an essential part of the Non-Trans Java Toll Road, which is a national strategic project aimed at facilitating economic activities in the southern part of East Java and improving connectivity to Kediri Airport. This study focuses on analyzing the economic and financial feasibility of the Kediri-Tulungagung toll road development project.The feasibility study involves assessing the project's viability, determining whether it should proceed or be delayed. The analysis includes evaluating traffic volume data, measuring road saturation levels before and after construction, and analyzing the transfer of road users to the toll road. Furthermore, an economic feasibility analysis is conducted to calculate savings in vehicle operating costs and travel time, as well as assessing metrics such as Benefit-Cost Ratio (BCR), Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PbP). Based on JICA 1 modeling and questionnaire responses, calibration values were determined for different vehicle classes. The economic feasibility analysis reveals a BCR value of 11,656 (BCR>1), an NPV of IDR 91,043,209,729,042 (NPV>0), and an IRR of 18.3811% (IRR>Interest rate). In the financial feasibility analysis using interest rates as discount rates, the BCR is 6,265 (BCR>1), the NPV is Rp 44,977,644,753,162 (NPV>0), the IRR is 11,872% (IRR>Interest rate), and the Payback Period occurs in the 24th year and 7th month after the toll road's operation. Based on these analyses, the Kediri-Tulungagung Toll Road is deemed economically and financially feasible when using interest rates as the discount rate.

Abstract

This study presents the effect of nano-silica (NS) from sandblasting waste as an additive on the mechanical properties of concrete mortar. The nano-silica was produced by using the sol-gel and mechanical grinding methods. In this research, nano silica material was added as an additive with a percentage varying from 0% to 5%. The results show that producing nano silica from sandblasting waste with a combination of sol-gel and mechanical grinding methods can produce an average size of 148.9 nm with 96.90% purities silica (SiO2). The compressive strength test also shows that adding NS can increase the compressive strength of the concrete. The highest compressive strength obtained from this research was. 29.76 MPa with the addition of 1% of nano-silica. This compressive strength is 37.5% higher than the control mixture.

Abstract

The express liner program also known in Indonesia as "Tol Laut", initiated in 2015, aimed to reduce price disparities between Java and eastern Indonesian regions by providing regular and sustainable shipping services to remote areas. However, after seven years, the program has not significantly affected price disparities in eastern Indonesia. To evaluate the program's effectiveness, this study examined port performance and economic changes resulting from Sea Toll. The study identified areas of improvement for Larantuka, Lewoleba, and Kalabahi ports, such as docks, terminals, access roads, and storage facilities. Port performance evaluation revealed that Larantuka Port had subpar utilization of docks and stacking fields, while Lewoleba Port exhibited poor dock usage. Kalabahi Port, on the other hand, demonstrated good performance in dock utilization and stacking field usage. Regarding ship services, Larantuka Port showed good waiting time performance but poor loading and unloading productivity and ship effectiveness. Lewoleba Port had unfavorable waiting time in 2021 but improved in 2022, while its loading and unloading productivity and effectiveness were poor in both years. Kalabahi Port demonstrated good waiting time and effectiveness, but its loading and unloading productivity fell short of the standard. Evaluating the economic impact, the Sea Toll program did not significantly reduce the prices of necessities. Certain commodities experienced price increases influenced by regional distances and price fluctuations in Surabaya. However, medium rice prices decreased significantly in Larantuka and Kalabahi, indicating a positive impact of the Sea Toll program in those areas.

Abstract

Indonesia was located in a seismically active region and was situated between three tectonic plates. The construction resilience that met the requirements was necessary in earthquake-prone areas. The purpose was to protect and reduce the risk of severe damage caused by significant seismic loads. However, more than 70% of buildings in developing countries like Indonesia utilized the Confined Masonry (CM) structural system. The implementation of CM systems in Indonesia often led to fatal damages during earthquakes. Due to the severity of these damages, the addition of reinforcement systems to CM became one of the options to address the shortcomings of the CM system. There were various types of materials that could be used as reinforcement, such as steel cages, polymers, polypropylene bands, bamboo meshes, and plastic materials. This study investigated the utilization of ferrocement layers as reinforcement material for CM structural system panels. The specimen panels used had a width of 2300 mm and a height of 1370 mm. The specimens in the research were numerically modeled using the ABAQUS/explicit program. The research variation focused on the influence of the wiremesh sheet orientation angle. The number of variations for the ferrocement layer was one layer with angle configurations of 0, 45, and 60 degrees. This reinforcement layer was applied to one side of the CM panel. As a comparison, results from the control specimen were included. The hysteresis curve, energy dissipation, stiffness degradation, and damage patterns were evaluated in this research.

Abstract

Indonesian houses are characterized as non-engineered and vernacular, constructed using local material, techniques, and architectural style. As a results these houses are typically built without the involvement of experts. In Indonesia, most lower class houses are unreinforced masonry (URM), masonry without structural elements. The absence of structural elements makes URM highly vulnerable to earthquakes and makes the masonry walls the main load bearers. This study analyses the performance of corner joint masonry wall with perforated plate to enhance the integrity between the perpendicular walls. This research was carried out experimentally. The results indicate that URM joint corner walls without perforated plates has the highest load capacity and ductility. Perforated plates in layers of masonry walls can decrease the lateral load capacity by 55%. The failure pattern occurred are slip failure, with cracks appearing at mortar-brick joint and mortar-perforated plate interfaces. From the test that have been carried out, it was found that perforated plate could reduce the cohesiveness of the walls rather than enhance the integrity of the perpendicular walls.
