Abstract

This study presents the effect of nano-silica (NS) from sandblasting waste as an additive on the mechanical properties of concrete mortar. Sandblasting process in shipping repair industry generate massive waste of silica sand. The silica sand produced from this process has quite fine particles and contains impurities such as residual rust, paint and other materials so it is dangerous for health if not used properly. In this research, 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 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 assess several parameters 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 a value and b value were recalibrated until they reach the appropriate values. 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

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 Express Liner. 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 Express Liner 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 Express Liner 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 moment resisting frame. The absence of those frame makes URM highly vulnerable to earthquakes and makes the masonry walls the main load bearers. This study analyses the performance of corner joint masonry walls with perforated plates 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 that occurred are slip failure, with cracks appearing at the mortar-brick joint and mortar-perforated plate interfaces. From the tests 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.

Abstract

On national roads with high or equal average daily traffic compared to provincial roads, slurry seals are commonly used to protect the asphalt layer from damage and improve skid resistance. Interestingly, when applied to provincial roads, spot leveling treatments tend to have a longer lifespan than slurry seals, which often deteriorate within the same fiscal year. This creates a contradiction: provincial roads with lower traffic tend to benefit more from spot leveling, while national roads, with higher traffic, favor slurry seals. To address this discrepancy, further research is needed to understand the factors influencing method selection and compare the longevity of these treatments to their construction costs. The study utilized average daily traffic data to assess traffic conditions, surveyed road conditions to determine damage percentages and remaining service life for slurry seals and spot leveling, and then compared these findings with construction expenses. The Cumulative Equivalent Single Axle (CESA) value, reflecting traffic load characteristics, significantly impacts the service life of slurry seals, resulting in a 2.08-year difference and a handling cost of Rp. 12,949.29 per square meter per year. Drainage conditions also affect slurry seal longevity, with a 1.32 year service life gap and handling cost of Rp. 8,097 per square meter per year. Additionally, sidewalk conditions influence slurry seal service life, leading to a 0.52-year gap and a handling cost of Rp. 4,688.39 per square meter per year. Based on the data regarding service life gaps and handling costs, it is evident that the most influential factor on the service life of slurry seals is the Cumulative Equivalent Single Axle (CESA) condition on the road segment where the slurry seal is applied.
