Abstract

Companies often encounter several problems, one of which is the uncertainty in market conditions that can lead to company failure. All actions taken in each activity are initiated and determined by humans who are members of the company. Employee performance is one of the most dominant factors in improving company performance which many factors can influence. The effect produced by each factor will certainly be different for each individual. Therefore, this study was conducted to determine how much influence several variables have on employee performance. The population in this study were employees who had or are currently working on a BUMN construction project with a sample of 122 respondents. To test the established hypothesis, this study will use the Structural Equation Modeling (SEM) method with a software program to input data from the questionnaire results, and then it will be calculated to see how fit the proposed model is. There is one relationship path that has no significant effect, namely the relationship between work environment variables and work motivation variables.

Abstract

This paper presents a numerical parametric study of Concrete Encased Steel Column (CESC) due to centrically and eccentrically axial load. To model the confining pressure of rebar and steel profile, modified Mander’s equations was used. The non-linear sectional analysis was performed using an in-house NL-Column program using the fiber-based method. The CESC section was discretized using Netgen 2D meshing algorithm. The developed CESC model was validated using the available test results in the literature. After model was validated, parametric studies were carried out to investigate the behaviors of CESC with different concrete compression strength, confinement bar diameter, and confining space. The parametric studies found that the column with higher concrete compression strength tend to have higher axial and flexural capacity but reduce the overall ductility. Increasing the confinement bar diameter slightly increases the axial and flexural capacity and ductility on the other hand, utilizing tighter confinement space resulted in higher ductility but with small increase in axial and flexural capacity.

Abstract

Concrete-filled tubes (CFT) are gaining popularity due to their excellent performance under compression. Various materials have been used to produce CFTs. Their behaviour varied significantly due to the properties of the materials. In this study, numerous articles related to CFT were reviewed. The effects of carbon steel, stainless steel, fibre-reinforced polymers (FRP), plastic materials, and various kinds of concrete on CFT were observed. The fundamental principles governing the behaviour of CFT were then determined. The confinement effect of the tube was the key to the outstanding performance of CFT. CFT performed well when the tube had high compressive strength, elastic modulus, tensile strength, ultimate strain, and corrosion resistance. The concrete with high compressive strength and ultimate strain, as well as low elastic modulus and shrinkage, experienced greater strength enhancement under confinement. Nevertheless, confinement effectiveness was greatly affected by the slenderness ratio. Short CFT subjected primarily to axial loads was preferred.

Abstract

The hospital is one type of land use utilization which could cause vehicle attraction. It is estimated that the existence of the new Ar-Rozy Hospital would become a trip attraction. For this reason, it is necessary to conduct research to anticipate the magnitude of the movement attraction which would occur in the future due to the existence of the new Ar-Rozy Hospital. This study uses trip generation analysis at 3 existing hospitals located around downtown Probolinggo. The primary data used is a survey of vehicles entering and leaving the hospital, and the secondary one is data consisting of the number of polys, the number of practicing doctors, the number of medical staff, land area, number of rooms, number of beds. The result shows that all independent variables affect the occurrence of vehicle attraction. The best model suitable for representing the conditions of the hospital vehicle attraction is chosen based on the results of a significant regression model and consideration of the highest R2,  multicollinearity, and normality test, the best model is : Y = 91.754 + 0.623 medical staff R2 = 0.991.

Abstract

Steady road conditions determine the smooth running of land transportation to support economic activity. To achieve steady road conditions requires a good road management program. The government, through the agencies appointed as road administrators, needs funds to maintain the stability of the road itself. The process of budgeting funds for the implementation of the road through a process of proposals, discussions and determination of the budget. Determining the priority of the proposal requires a long discussion. The Provincial Government of East Java through the Department of Public Works of Highways has an important role in the process of handling provincial roads. Budget limitations, both Regular APBD funds and special allocation funds and other funds, create a distinct challenge for road administrators in determining an effective and optimal road management program. Based on previous research studies, priority determination of road handling can be carried out using Multi Criteria Analysis (MCA). Priority determination criteria used in this study are technical criteria which include: existing traffic conditions, road stability conditions, degree of saturation, travel speed, and travel time; financial and economic criteria which include: BOK, Time Value, BCR, and NPV. In this study it will be seen based on the results of prioritized maintenance handling found at Link 176 Kediri - Blitar City Boundary for LHR technical criteria has a difference in value of 3,190 cur/hour, with an average road condition of 27.12%, difference in degree of saturation of 0.346, the difference in travel speed is 3.409 km/hour, the difference in travel time is 3.661 minutes and for economic criteria BOK has a difference in value of Rp. 8,662,656,168, the difference in the BCR value is 0.60 and the difference in the NPV value is -Rp. 8,382,143,904.

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.
