Abstract

Pattern of interaction that occurs between the City of Surabaya and the City of Semarang is not only limited to economic factors but more than that the pattern of interaction takes place in all aspects of human life. People who are outside the Semarang City area will try to choose the fastest route from several routes that connect between the zones of origin to Semarang City. This research was conducted based on the factors that influence the process of selecting travel routes from the city of Surabaya to the city of Semarang using the inter-city inter-provincial bus (AKAP) public transportation. This study uses a gradual loading method because this method can be used to determine the relationship between traffic flow and vehicle travel time, not depending on the assumptions of road users and the characteristics of the road network. The results of simple linear regression analysis, obtained a flow-cost relationship model on route A (Terminal Purabaya - Nganjuk - Ngawi - Solo - Ungaran - Terminal Terboyo) the form of the equation is YA = 48.937 + 0.022X. While the flow-cost relationship model on route B (Terminal Purabaya - Gresik - Lamongan - Tuban - Rembang - Kudus - Terminal Terboyo) the form of the equation is YB = 36,822 + 0.034X. The coefficient of determination (R2) on route A is 0.6 and on route B the result is 0.4. The final result of loading the travel route with a uniform loading fraction of 5% obtained a Wardrop balance convergence value of 0.003. Keywords: simple linear regression analysis, stepwise loading method, travel route selection.

Abstract

Highways can have an impact on the social and economic development of the surrounding community as well as progress in the industrial sector. Road safety is an important aspect that must be considered. The main problem that often occurs in these accidents apart from human factors can also be caused by road infrastructure. Along Porong Arterial Road – Roadway Purwosari STA 30+00 – 61+400 in certain locations along the road there are inadequate road completeness facilities such as PJU lights that do not turn on or PJU distances that are too far away, pavement damage and road markings less clear. Based on these field conditions, it is necessary to evaluate traffic safety based on the main attributes that must be repaired using the Importance Performance Analysis method, namely the street lights are on well, damaged roads have been replaced/repaired and roads are free from damage such as waves, potholes. and puddles. According to the weighting with the EAN (Equivalent Accident Number) method based on data from the Police Resort of Sidoarjo Regency and Pasuruan Regency in 2016 - 2020 it was 486, located at STA 38+00 – 39+00 with a total of 590 cases. The blackspot point is located at the Apolo Roundabout with (R analysis) > (R Existing) = 30 m > 18.03 concluded that it does not meet the standards and the value of side freedom and (E analysis) < (E existing) = 5m < 7 m is concluded to have met the standard.

Abstract

Passenger Car Equivalent (PCE) is a conversion factor of various types of vehicles compared to passenger cars or other light vehicles concerning their impact on traffic behavior. The PCE value used in calculating the performance of urban roads refers to Manual Kapasitas Jalan Indonesia (MKJI 1997) as an Indonesian Highway Capacity Manual. There have been many changes in traffic behavior nowadays compared to in 1997. The calculation of the PCE MC value using the average time headway method does not match the actual conditions. Therefore, modifications are needed by calculating the vehicle dimension factors to obtain the PCE value. The result of the PCE MC calculation using the modified average time headway method shows 0.17. This value is smaller than the value of the PCE MC set by the MKJI 1997, which shows 0.25. Based on the analysis of traffic conditions for ten years, the DS value using the PCE MC according to the MKJI 1997 obtains DS>1. Meanwhile, the DS value calculated based on the corrected PCE MC has DS<1. The difference in the value of PCE MC has implications for road performance. As a result, it affects traffic maintenance management in the form of maintenance costs and decision-making.

Abstract

Investment is a commitment to several funds or other resources carried out at this time, intending to obtain some benefits in the future. Investments can be associated with a wide variety of activities. Investing many funds in real assets (land, gold, machinery, or buildings) or financial assets (deposits, stocks, or bonds) is an investment activity that is generally carried out, especially for developers. So that before stepping into the development stage, it is necessary to conduct a feasibility study first to be able to state whether or not the development of a project is continued. This study takes a case study of RUKO (Rumah Toko) in the Sidoarjo area, namely Ruko Citra Harmoni, and in its financial analysis uses discounted cash flow analysis. From the analysis results obtained: (1) Total development costs (development costs) calculated from the cost of DC phase, I added to the DC phase II is Rp. 3,831,665,014, -. (2) Loan from 60% development cost (DC) which is Rp. 2,298,999,008,-, while the remaining 40% of Rp.1,532,666,006,- is equity. So that the Debt Service from the loan that must be paid annually is Rp. 285,075,877,-. (3) The net present value obtained is Rp. 1,389,027,781,- during 30 years. (4) Internal rate of return (IRR) = 18.47 % > discount factor (DF) 16%. (5) Payback period is 23.8 years. (6) BCR > 1, i.e. 1.29 > 1. So from the several assessments above it can be stated that the Royal Business Regency Ruko Palm Project is feasible to work on and carry out construction

Abstract

The fundamental goal of project management is to finish a facility building project on schedule and within budget while adhering to defined standards and specifications. No matter how great the construction project plan is, if frequent and timely reviews are not done throughout project execution, neither the project progress nor the plan's efficacy can be evaluated. The Earned Value Method (EVM) is one of the tools used in project management that integrates scope, cost and time or schedule measures and provide an accurate picture of current project state at the time of control. This research implements the EVM to road construction project to observe the project performance during its execution and to estimate the cost and the duration of the project completion. Based on the calculation, the project team has efficient performance in using their time and cost for week one until week three, but it decreased especially in time of execution (0,864 of SPI value). Further calculations predict the project needs to prepare Rp. 115.935.300,00 to finish with Rp. 264.828.113,00 of total cost while the TE value shows this project will be finished one week behind its initial planning if no corrective action is done.

Abstract

A toll road is one of the economic growth facilities of a country, Indonesia in the last seven years has succeeded in building 1900 km and one of them is Trans-Java. The Gempol-Pasuruan section-2 toll road project is a densely populated route and there are many intersections in the form of roads and rivers so there are many overpass or underpass structures in the project. Although the bridge structure is a sub-project of the main road, if the productivity does not perform well, it will have a significant impact on the overall progress. Therefore, this study wants to analyze the multiple impacts of one of the critical works of the bridge project, such as the pilling work on the total toll road progress through the earn value management (EVM) method. EVM is a technique that is quite popular both among practitioners and academics; however, analysis of complex projects (main projects-sub projects) has never been carried out in-depth and it will be a unique challenge in this study. There are four steps in this research, the first step is project scheduling in which the engineer can use the previous database to prepare the work breakdown structure (WBS), work sequences, and project duration. The second step is the critical path process, at this stage, a slack analysis is carried out for each activity, and setting a network diagram to generate critical paths for the toll-bridge project. Resource management is the third step that involves a lot of documents from the market and internal databases, starting with assigning resources, inputting quantity and unit prices, and doing the leveling process so that the supply chain runs well. The last step is the earn value process, at this stage, the engineer only needs to input the project progress, set the baseline, and finally get the earn value project and project performance index consisting of SPI (schedule) and CPI (cost). Finally, after going through several stages of research, it has been proven that the pilling work is on a critical path and several scenarios must be carried out to maintain its productivity. Then, the average SPI value is 0.94 < 1, while the SPI value is 1 which means that the Gempol-Pasuruan section-2 toll road project is experiencing delays and is within the project budget. In conclusion, the application of the EVM method on MS. Project 2013 is able to evaluate complex projects well and several potential technologies can also be considered in further study to improve the performance.

Abstract

The campus is critical to learning because it provides a comfortable environment. If there is a disturbance in the environment, such as noise, the teaching and learning process will be disrupted. The purpose of this study was to assess if the noise level outside the campus area next to the recreation area adheres to the calculation standards outlined in Minister of State for the Environment Decree No. 48 of 1996, with a +3 dB tolerance (A). Because the research location is close to a road and adjacent to residences, the results at point 1 meet the quality criterion, however the results at point 2 are one decibel lower. When recreational guidelines are followed, the environment's standard regulations are met.
