Abstract

Abstract Land transportation traffic accidents in Indonesia were affected by the Covid-19 pandemic. During the Covid-19 pandemic, several transportation policies were implemented. An absolute must for implementing transportation safety. During the Covid pandemic in 2019 and 2020, the average number of traffic accidents was 25%, the number of fatalities was 24%, the number of injured victims was 21% and the number of accidents was 25%. In 2021, Indonesian people will begin to face new normal conditions, where all activities run normally in line with the presence of the Covid 19 virus. So that in 2021 and 2022 there will be another increase in the number of traffic accidents, deaths, injuries and accidents. The average figures for 2021 and 2022 for the number of traffic accidents are 26%, the number of fatalities is 26%, the number of injured victims is 23% and the number of accidents is 28%. With the presence of Regulation Number 21 of 2020 concerning PSBB, the number of accidents in Indonesia can be reduced, but the reduction in the accident rate has not occurred significantly. In 2019 the accident rate was 31% and in the year the PSBB policy was implemented the accident rate was 23%, the reduction in the accident rate was only 8%.

Abstract

Jalan merupakan prasarana transportasi yang penting dalam pertumbuhan pembagunan social dan ekonomi. Karena keterbatasan dana, maka perlu menentukan prioritas perbaikan jalan. Agar penanganan jalan berjalan optimal, diperlukan kriteria yang menjadi prioritas utama untuk dipertimbangkan dengan seksama.Pemilihan kriteria yang tepat merupakan aspek yang perlu dikaji karena kondisi dan kebutuhan setiap daerah akan prioritas perbaikan dan peningkatan jalan akan berbeda. Pendekatan analisa yang digunakan pada penelitian ini adalah Multi-Criteria Decision Making (MCDM) dengan mengunakan expert choice. Dalam penelitian ini, hirarki AHP yang digunakan adalah hirarki fungsional yang terdiri dari 3 level yaitu tujuan (level 1), kriteria (level 2) dan sub kriteria (level 3).Kuesioner disebarkan pada 19 responden untuk menemukan bobot kriteria dan subkriteria yang menjadi prioritas pemeliharaan ruas jalan di Kabupaten Pasaman, Provinsi Sumatera Barat. Dari 6 kriteria dan 23 sub kriteria, setelah dilakukan analisis dengan mengunakan Expert Choice, terdapat 5 kriteria dan 19 sub-kriteria yang memenuhi persyaratan nilai CR 0,1. Dalam menetapkan urutan kegiatan pemeliharaan jalan di Kabupaten Pasaman, bobot diberikan pada beberapa faktor, seperti kerusakan jalan (30,90%), aspek ekonomi (19,70%), kebijakan (18,10%), lalu lintas (16,00%), dan tata guna lahan (9,60%). Hasil dari model ini selanjutnya di aplikasikan kepada 12 ruas jalan yang membutuhkan pemeliharan.

Abstract

Abstract The construction industry, as a major sector employing a significant portion of the workforce, contributes approximately 8% to global GDP but faces a high fatality rate of 30–40% in workplace accidents. While numerous studies have explored factors influencing construction safety performance and conducted systematic literature reviews, reviews specifically focusing on strategies to enhance safety performance remain limited. This study aims to address this gap by performing a systematic literature review using the PRISMA protocol to identify strategies for improving construction safety performance. Based on the review, five key strategies that can reduce workplace accidents include proactive safety management, emphasizing project management commitment and safety management systems; comprehensive safety training, focusing on priorities, methods, and facilities; systematic safety inspections, covering frequency, procedures, and outcomes; systematic safety budget allocation, addressing incentives, equipment procurement and maintenance, and safety personnel salaries; and prevention through safetyoriented construction design. The study also provides recommendations for future research. Keywords: Safety performance, strategies, construction industry, systematic literature review, PRISMA

Abstract

Abstract Unpredictable climate change makes high intensity rainfall infiltration possible in the future. This can cause slope collapse due to rainfall infiltration. Indonesia has areas that are very susceptible to slope collapse due to rainfall. The purpose of this study was to determine the characteristics of the pore water pressure distribution and slope stability during rainfall on the original slope through numerical modeling. The groundwater characteristic curve was measured using high-suction polymer sensors (HSPS). Volume changes in the soil were obtained using a 3D scanner. Numerical modeling was carried out with the help of GeoStudio. Seepage analysis was carried out using SEEP/W to obtain changes in the pore water pressure distribution due to rainfall infiltration. Slope stability was carried out using SLOPE/W to determine the slope safety factor due to rainwater infiltration. The results showed that the intensity and duration of rainfall had a significant effect on slope stability. The longer the duration of rainfall and with high intensity can cause a greater decrease in the safety factor. This is because the suction power of the soil has decreased and causes the shear strength of the soil to be lower so that it can cause slope failure. Keywords: Unsaturated soil, SWCC, rainfall infiltration, slope stability

Abstract

Abstract Constructing a hotel have to include various facility. One of the many may a jogging track. We take the Aruss Hotel in Semarang, Central Java, as the case to be studied. The Hotel planned to use Ironwood as the material for the track due to its solid and resistant characteristics. However, using the wood material collectively adds more pressure to the rainforest. Therefore we propose to replace the Ironwood with andesite stone. The andesite material also has solid and resistant characteristics. We argue that materials usage should consider the sustainability aspect of materials and the Value for Money factor. Therefore, the objective of this article is to provide a perspective for decision-makers that includes the sustainability perspective and the VFM principle. We conducted two activities during the Research: (1) comparing the cost of both materials and (2) comparing the time consumed installing both materials. The analysis results are as follows: The cost of using andesite is 73% cheaper than Ironwood. We replaced the Ironwood with an andesite, which is proven to save IDR 307,031,041. Moreover, using the andesite only takes 13 working days, while Ironwood takes 36 days. We conclude that using andesite as the alternative to Ironwood has two advantages: (1) reducing the pressure on the natural forest, and (2) saving the construction cost.

Abstract

Abstract Liquefaction is phenomenon of the loss of shear strength of saturated sandy soil. Liquefaction has become one of the primary concerns for Indonesia and the world, especially after the occurrence of liquefaction in Palu due to Palu-Donggala earthquake. Learning from the liquefaction phenomena after the Palu-Donggala earthquake event on 28 September 2018, many researchers have conducted liquefaction and flow slide study. In order to complete the study of the liquefaction phenomenon, an experimental study using shake table, chamber, and piezocone is conducted to evaluate the behaviour and viscosity of liquefied silty sand material. Based on the observation during liquefied condition, the silty sand material will experience an increase in excess pore pressure and a decrease in tip resistance. In addition, it is also known that sleeve resistance, speed of penetration of the piezocone, and zone of influence due to piezocone penetration are the main keys in determining the viscosity of the silty sand material during liquefied condition Keywords: Liquefaction, viscosity, silty sand, piezocone

Abstract

Abstract The water mass exchange process between a bay and an open sea can flush effluents or pollutants that enter the bay. This paper describes a two-dimensional numerical modelling study on thermal water dispersion due to hydrodynamic processes in The Bontang Bay and the bay flushing capability. The numerical model used is Delft3D. Model input data was including bathymetry, water elevation, discharge of seawater intake and outfall, wind speed, and temperature of the thermal water effluent discharged into Bontang Bay. The modelling results were verified with observation data. Verification results shows that error of water elevation is 0.07 m, while current speed error is 0.26 m/s. Dispersion modeling results indicate that 40°C thermal water discharged at a rate of 24.6 m³/s into Bontang Bay has increased the water temperature in the bay by 1°C to 2°C. This increase in temperature potentially has a negative impact on aquatic ecosystems. An increase in water temperature of 1°C and 2°C covers areas of 19.32 km² and 7.26 km² in the bay, respectively. The residence time of thermal water in Bontang Bay is 3 days and 12 hours before flushing. Keywords: Thermal dispersion, exchange process, residence time, flushing time

Abstract

Abstract Better Value for Money (VFM) is a key reason The Government opts for Public-Private Partnership (PPP) schemes in infrastructure project delivery. The Government has developed a quantitative VFM measurement methodology based on the Public Sector Comparator (PSC). A critical issue within this methodology is determining the appropriate discount rate for PSC and PPP cash flows. This paper aims to evaluate the impact of various discount rates on VFM. Four discount rates are analyzed: the project rate, the risk-free rate, the social discount rate, and a modified project rate. Two approaches are considered: applying the same discount rate and using different rates for PSC and PPP. The findings reveal that differing discount rates, even with identical cash flows, result in variations in VFM. When the same discount rate is applied to both PSC and PPP, the VFM is negative unless the discount rate equals or exceeds the project rate. Moreover, the greater the spread between PSC and PPP discount rates, the lower the VFM when the PSC rate is higher, and the higher the VFM when the PPP rate is higher. This paper recommends the development of more detailed guidelines for determining discount rates to prevent VFM miscalculations, which can result in misleading decisions.

Abstract

Abstract A study was conducted on the manufacture of polymer mortar using Polyethylene Terephthalate (PET) as a substitute for sand with a composition of 0%, 0.2%, 0.5%, 0.8%, 1.1%, 1.4% and Ethylene Vinyl Acetate (EVA) polymer composition of 0%, 2%, 4%, 6%, 8%, 10%. Sand, cement and polymer materials were weighed and molded into a size of 16 × 4 × 4 cm3 and soaked in water for 7 and 14 days. The highest flexural strength value obtained at 14 days of immersion was 6.50 MPa, porosity at 7 days of 12.20%, absorption value at 7 days of 6.65% and density at 14 days of 1.89 g/cm3 with a polymer substitution composition for sand of 10% EVA polymer: 1.4% PET. Characterization of the sample was carried out using X-ray Diffraction (XRD), X-ray fluorescence (XRF), Scanning Electron Microscope- Energy Dispersive X-ray spectroscopy (SEM-EDS), and Fourier-transform infrared spectroscopy (FTIR). XRF characterization obtained CaO of 46.95% and SiO2 of 24.45%, which is the result of CS-H formation. XRD characterization obtained calcite, quartz, corundum, hematite phases. SEM-EDS images show a cauliflower-like morphology and dominant elements of Ca and Si. FTIR functional groups are O-H, C=O, C-C, C-H, Si-O-Si, and Si-O is a portlandite group. The increasing addition of EVA and PET polymers results in high porosity and high flexural strength. Keywords: Polymer, mortar, EVA, PET, and characterization.

Abstract

This study examines the performance of asphalt concrete mixtures using foamed bitumen derived from extracted Buton natural asphalt (Asbuton) in comparison to conventional penetration asphalt (Pen 60/70). The research focuses on evaluating key parameters such as aggregate properties, Marshall stability, indirect tensile strength, and other mix characteristics, benchmarked against Indonesian national standards. Asbuton, known for its high viscosity and resistance to extreme conditions, offers an alternative binder for sustainable road infrastructure development. The results demonstrate that foamed Asbuton significantly outperforms Pen 60/70 in critical metrics. Foamed Asbuton achieved higher stability (2440.8 kg) and a superior tensile strength ratio (92.78%), reflecting its robustness under heavy loads and resistance to moisture-induced damage. In contrast, Pen 60/70 exhibited reduced stability and rigidity when subjected to the foaming process. The enhanced performance of foamed Asbuton is attributed to its dense structure and the benefits of the foaming process, which improves aggregate coating and binder distribution at lower mixing temperatures. This study highlights the potential of foamed bitumen technology, particularly when paired with high-performance binders like Asbuton, to improve the durability and sustainability of road infrastructure. Foamed Asbuton emerges as a promising material for high-stress applications and extreme environmental conditions.
