Abstract

The development of construction methods used in construction has progressed from year to year and in planning the construction of a building it is necessary to select several construction methods. Among them are casting methods that can be done conventionally in a more modern and practical way, namely by using precast. In this research, the floor slab construction method is planned using the conventional floor slab method and the precast half slab method in the Kajen Regional Hospital construction project. The purpose of this research is to analyze the cost efficiency and construction time between the conventional floor slab method and the precast half slab method. The results of the comparison analysis of the conventional floor slab method require a cost of Rp797,269,777.81 with an implementation time of 64 days while the precast half slab method requires a cost of Rp1,470,907,469.89 with an implementation time of 72 days.

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.
