Abstract

The development of construction planning, especially in the construction of building structures, calculates unit prices using a tool called Construction Cost Analysis (ABK), where until now the method often used by contractors and consultants is the BOW (Burgerlijke Openbare Werken) guideline. However, as time went by, it was realized that the BOW guidelines were only segmentally suitable for projects in the form of labor-intensive work that utilized conventional equipment and less professional workforce, which resulted in very expensive planning costs if this approach was still used purely. The 2008 Indonesian National Standard (SNI) analysis method is an update of the 1921 BOW (Burgerlijke Openbare Werken) analysis during the Dutch government, in other words, the SNI analysis is an updated BOW analysis. This SNI analysis was issued by the Center for Settlement Research and Development. The cost preparation system using SNI analysis is almost the same as the calculation system using BOW analysis. The basic principle of the SNI method is that a list of coefficients for materials and labor costs has been determined to analyze the price or costs required to make a unit price for building work. From these two coefficients we will get a calculation of the materials needed and a calculation of the wages of those doing the work. The comparative composition and arrangement of materials and labor for one job has been determined, which is then multiplied by the price of materials and wages prevailing in the market.

Abstract

The Sunut Bridge is a bridge that crosses the Jragung River which connects Semarang Regency and Demak Regency. The initial planning for the Sunut Bridge used a prestressed concrete structure with a total length of the main bridge of 60 meters. This bridge is divided into 4 parts. From the author's assessment, the use of prestressed concrete structures with many pillars is considered to cause design waste and give the impression of stiffness to the bridge. Apart from that, seeing that the condition of the river during floods often brings flooding, thereby reducing the effective linear waterway of the river, a bridge construction was re-planned with minimal pillars using an arch structure. In this planning, the Sunut Bridge was re-planned to use a steel arch structure type A Half Through Arch Bridge. From the planning results, the vechile floor plat tickness was 23 cm. The longitudinal girder profile used is WF 800x300x16x30 and the cross girder profile WF 900x300x16x28. The next stage of calculating the primary and secondary structures is carried out by calculating the working loads which refer to SNI 1725:2016 and RSNI T-02-2005 regulations to obtain a box prifile for the main structure of the arch bridge.

Abstract

Many people still use private vehicles, making BRT's function as a solution to overcome congestion not optimally realized. The aims of this study were: 1) to determine the supporting and inhibiting factors for the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor); 2) determine the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor). This research uses a quantitative approach. Data collection techniques are observation, interviews, and documentation. Data analysis technique is descriptive statistics. The research results show that the supporting factors for the BRT Trans Semarang service are the dominant flat and wide roads, so that large buses can be used. The inhibiting factors in BRT Trans Semarang services are the absence of a special lane for BRT Trans Semarang, so waiting times and fleet intervals are still very dependent on existing traffic conditions. How to overcome the inhibiting factors in BRT Trans Semarang services, namely planning a special route for the Jrakah intersection to the Pedurungan intersection with a length of 12.8 km to improve service and reduce passenger waiting time, as well as improve fleet intervals. While the effectiveness of BRT Trans Semarang service corridor I Mangkang-Penggaron obtained a total average percentage value of 84% in the very good category. The results of the one sample t-test that have been carried out obtained a sig 2-tailed value of 0.000 0.05, indicating that Ho was rejected, so the average value of the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service corridor I Mangkang-Penggaron is not the same with 80. It can be concluded that the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor) has been running effectively.

Abstract

Construction activities in road infrastructure development are never separated from earthworks which often become obstacles due to differences in land contours due to excavation and embankment work which is closely related to geotechnical engineering. Embankment and excavation are very interesting things to study because they are closely related to slope safety factors and require special handling. In this research, we examine the use of geotextiles by comparing the handling using safes on embankment stability using PLAXIS Version 8.2 software. The results of embankment stability analysis with safes, settlement at 1 year consolidation was 5.6 cm and settlement at 10 years consolidation was 5.7 cm. in accordance with applicable criteria. The results of the analysis using 2 layers of geotextile showed that the settlement at 1 year consolidation was 4 cm and at 10 years consolidation was 4.1 cm, which is in accordance with the applicable criteria.. Meanwhile, the results of the slope safety factor using bract treatment at 1 year consolidation were 1.475 and the safety factor for 10 year consolidation was 1.478, not in accordance with the design criteria of 1.5. The results of the safety factor using 2-layer geotextile treatment at 1 year consolidation was 1.853 and the safety factor for 10 year consolidation was 1.855, which is in accordance with the design criteria of 1.5.

Abstract

The 2023 Neucentrix Expand Enhancement Development Project Pugeran Yogyakarta is planned to last 19 weeks. However, there was a delay due to the large amount of additional work and new items that were not listed in the BoQ. This research aims to identify the main factors causing project delays. The data used came from a questionnaire and then factor analysis was carried out using SPSS. A total of 11 managerial team respondents filled out the questionnaire, producing 18 valid variables that were very reliable. The results of the analysis show 5 rankings of the main factors causing delays, namely: delayed payments have an impact on project delays; changes in costs due to additional work; less than optimal labor productivity; error in basic price estimation in the Cost Budget Plan; difficulty in finding materials and/or equipment due to certain specialties; submission and request for changes to completed work from the project owner; changes in work methods by contractors; lack of adequate workforce; owner's delay in making decisions; changes to the scope of work (SOW) during implementation; and lack of workforce discipline regarding attendance and attendance, which hampers work time

Abstract

Due to the high mobility of those passing by and the presence of trains that cross the intersection between the highway and the railroad, also known as level crossings, Jalan Hasanudin experiences heavy traffic during rush hour. Additionally, because of the large volume of train traffic at the Poncol station and the proximity of this intersection to the station, there is frequently a buildup of vehicles at the level crossing on Jalan Hasanudin. As a result, researchers will determine how Jalan Hasanudin Semarang performed. After conducting research, it was discovered that the highest vehicle queue length occurred on Monday, February 27 2023 from Jalan Hasanudin - Imam Bonjol at closing time 16.45 with a queue length of 123 meters and the highest stop delay occurred on Saturday, March 4 2023 from the direction of Jalan Hasanudin - Imam Bonjol with an average stop delay duration of 372.00 seconds. Therefore, the occurrence of long lines led to fuel losses for the drivers; their total gasoline loss over the course of the three research days was IDR 886,550.7. The researchers offer recommendations based on the findings of the research analysis to control street vendors and people near railroad tracks and railroad crossings that result in side barriers and long lines during stop delays, install traffic signs like those that prohibit stopping, prohibit parking, and prohibit raising and lowering passengers on roads, and so that there is no congestion along Jalan Hasanudin and around railroad crossings.

This research aims to determine the level of service at the Penggaron terminal using the importance performance analysis (IPA) method. This research was conducted at the Penggaron type-B terminal for two weeks, the first week the questionnaires were distributed to respondents on Mondays and Sundays in the morning at 07:00-10:00 WIB and in the afternoon at 16:00-18:00 WIB. This research is included in the quantitative research with a descriptive research approach. Data collection uses primary data, namely data obtained from the answers of the respondents to the questions posed by the researcher. Secondary data from literature study in the form of documents, laws and regulations, journals, scientific papers, supporting data relating to the problem under study. Based on the results of data analysis and processing using the Importance Performance Analysis (IPA) method in the Cartesian diagram, the service facilities at the Penggaron bus terminal are dominant in quadrant 2, which shows high expectations and reality, and quadrant 4, which means expectations of low use and high reality. However, there are a small number of service facilities that are in the quadrant, which means that the expectations from users are high but the reality is low. So, based on user evaluation, the service at the Penggaron terminal is quite good.
