<![CDATA[The most common impediment to project work is a delay in implementing work activities. Even though the completion time has been calculated, there are several influencing factors, such as natural factors that cannot be predicted, late material delivery, a lack of workers that are not optimal when doing project work, and insufficient funds. In this case, the construction project of the Kampung Akuarium flats in Penjaringan area of North Jakarta was delayed from both technical and non-technical. The objective of this study is to identify the factors causing the project delays and the delay time of the project. This research was conducted by collecting data obtained and processed using Microsoft Project 2019 and the Critical Path Method (CPM) to help identify the problems. From the results that have been analyzed, critical paths include the structural work, finishing architecture 3rd floor, finishing architecture 4th floor, and finishing architecture 5th floor. If not completed immediately or delayed during implementation, the entire project schedule will be delayed. This has an effect where the initial contract plan was completed in 182 days to 259 days with a difference of 77 days or 11 weeks.]]>

<![CDATA[Concrete is a material that is widely used in the construction of structural buildings. One of the influential factors for obtaining high quality concrete is the aggregate gradation. If the aggregate gradation has a small size and varies, it can reduce the porosity of the concrete so that the concrete becomes denser which makes the quality of the concrete high. In order to use aggregates with fine gradations, this study proposes glass powder derived from glass bottle waste as a partial replacement for fine aggregates. The glass powder used is in the sizes about 0.150 mm - 0.075 mm. Then, the maximum size of 15 mm for the coarse aggregate and the fine aggregate with the gradation of zone 4 (fine sand) were used for the concrete mix. The purpose of this study is to investigate the mechanical properties of concrete i.e. the compressive and split tensile strength of concrete with glass powder as a partial substitution of fine aggregates with a percentage of 10%, 15%, and 20% at a concrete age of 28 days. This study uses the testing method that refers to ASTM standard. From the test results, it was found that the compressive strength of concrete with 20% glass powder variation (GPC 20%) increased by 11.32% with a value of 38.97MPa compared to the compressive strength of normal concrete (NC) with a value of 35.01 MPa. For the split tensile strength, the concrete with a 20% glass powder variation increased by 15% with a value of 2.71 MPa compared to the split tensile strength of normal concrete with a value of 2.36 MPa. The results showed that the use of glass powder as a partial replacement for fine aggregate in this study was reasonably good to improve its mechanical properties.]]>

<![CDATA[Karawang district was formerly known as a rice barn in West Java. But now, this area has become one of Indonesia's largest industrial districts. Its great potential increases the community’s demand for business places. Therefore, the high activity of an area must be balanced with the fulfillment of infrastructure facilities. In maintaining adequate road conditions, it is necessary to provide an integrated drainage system between the road drainage system and the drainage system of the surrounding area. This paper is objective which is to evaluate the capacity and performance of existing road drainage channel. As the land use changes, it’s crucial to evaluate the increase rainfall water runoff. By collects and evaluating recent rainfall data and hydrological analysis using the Normal, Gumbel, Log Normal, and Log Pearson III methods to determine the design rainfall in South Karawang. The results of rain data processing obtained by the selected parameters test method are the Log Pearson III with 10-years of rainfall design 141.26 mm. After conducting capacity evaluation, the results show that the existing channels that serve the area (A) of 8.37 ha with the runoff coefficient (C) of 0.89 are needs to be increases to accommodate the surface rainfall water runoff discharge of, Q = 3.26 m3/s. Thus, a precast concrete U-Ditch of 1200 x 1400 mm will provide effective 400 mm of freeboard, W, and 0.5% as channel slope (s) is designed with channel discharge (Qchannel) of 3.39 m3/s to accommodate the needs of current conditions.]]>

<![CDATA[Earthquakes frequently occur in Indonesia because it is an earthquake-prone area. Due to lateral load from an earthquake can cause a weakly constructed building to collapse. Designers often only consider tall buildings in designing earthquake-resistant building structures but ignore earthquake-resistant designing for low-rise buildings. This study focuses on the analysis of earthquake resistant structures with a case study of low-rise buildings in the form of a 3-story reinforced concrete (RC) building in the South Jakarta area. The objective of the study is to analyze the base shear and story drift of the structure due to lateral or earthquake loads. The structure is a reinforced concrete with the concrete compressive strength of  = 30 MPa and longitudinal reinforcement of  = 420 MPa and stirrups of   = 280 MPa. This study uses equivalent static analysis manually and using ETABS 20.1.0 application. The results showed that three story buildings analyzed using equivalent static analysis method and using ETABS 20.1.0 application had almost the same results on horizontal forces with manual result of 1680.97 kN and ETABS of 1648.46 kN. The elastic story deflection and inelastic story drift in this study are still within safe limits because it is below the drift limit.]]>

<![CDATA[This study deals with the modeling of prestressed concrete components and its effects on the behavior of the structure. Two cases are presented, i.e., simple vs continuous beams, and crossing of prestressed and reinforced concrete beams. Based on the findings in this study, the modeling has significant effects in prestressed concrete behavior. The effects might create serious problems on structural safety if not addressed properly in the analysis and design of prestressed concrete systems. As much as possible, it is best to design prestressed components as free-standing statically determinate systems, thereby avoiding the possibility of additional secondary stresses that may reduce the capacity of the designed member. To achieve the above goals, it is best to use a precast concrete system to build a prestressed concrete system.]]>

<![CDATA[This study presents a comparative seismic performance analysis of a 10-story commercial building in North Jakarta, an area characterized by high seismicity and challenging geotechnical conditions. Two identical structural models were analyzed using ETABS v2022: one using a lightweight precast concrete panel system (JOE Green X3) and the other using a conventional Autoclaved Aerated Concrete (AAC) lightweight brick system. The aim is to compare the seismic structural performance of the analysis, based on the response spectrum method in accordance with SNI 1726:2019, revealed that the precast concrete panel system, was 14.4% lighter than the AAC lightweight bricks system when accounting for its full installed weight, including plaster and bracing columns. It resulted in a shorter fundamental period (0.412 s) compared to 0.453 s of the AAC lightweight brick system. However, the seismic base shear forces are nearly identical due to compensating effects in the site-specific response spectrum. Although both systems meet the deflection limits mandated by regulations, their performance is direction-dependent. This study concludes that the substantial reduction in total mass of the precast panel system provides a shorter vibration period but comparable seismic performance to the AAC lightweight brick system.]]>

<![CDATA[Malang sand has small and rough grains with a sharp surface, it can easily absorb water and adhere to cement. It is very suitable for use as fine aggregate in concrete to improve the quality and durability of concrete. As sand from a volcano, Malang sand has similar characteristics to sand from cold lava resulting from volcanic eruptions. In another study, concrete with sand from cold lava of Sinabung volcano was reported to have the highest compressive strength in a mixture variation of 60-70% of Sinabung sand at the age of 14 days. This study focuses on investigating the compressive strength of concrete with the addition of Malang sand as partly replacement of 50-70% of the fine aggregate material. The concrete design method uses practical guidelines for designing concrete mixes according to Indonesian standard (SNI), and for testing the compressive strength of concrete using ASTM C-39. The percentage of sand used in this study is 50%, 60%, and 70% as a substitute for fine aggregate with a concrete age of 28 days. Based on the study results, the maximum average compressive strength is achieved for the concrete with Malang sand of 70% (MSC 70%) with a compressive strength of 31.89 MPa or an increase 4.32% compared to normal concrete. In this study indicated that the trend of compressive strength is increase with the increase of Malang sand content in the concrete.]]>

<![CDATA[In the construction of the Pegadaian Tower project, the delays experienced were evidenced by the project implementation not being in accordance with the plans that had been designed before the construction process began. The project planning made by the contractor is planned for the topping off process or final floor casting of the superstructure construction phase to be carried out in September 2022 or in the 18th month of the total 25 months of work on this project. Efforts made to adjust the implementation of the plan were to accelerate this project, where the acceleration was carried out using the What/If method by adding working hours (overtime) and the number of workers at the research object who worked on the Mezzanine floor to the 5th floor at the superstructure stage. Apart from the What/If method as an acceleration solution, initial efforts were made by evaluating the project schedule using the Precedence Diagramming Method (DPM) network planning method with the help of Microsoft Project software. The analysis carried out resulted in good acceleration where the acceleration analysis using the What/If method can speed up the completion of superstructure construction so that it can help achieve the topping off target in September according to what has been planned in the schedule. Meanwhile, adding labor and working time to these three important activities can speed up the duration of the project so that the project avoids contract loss penalties with the owner.]]>

<![CDATA[Concrete material has moderately strong compressive strength, but relatively weak tensile strength. To overcome this problem, three kinds of systems can be applied, namely reinforced concrete system, composite concrete system, and prestressed concrete system. In a prestressed concrete system, a compressive force is applied to annihilate the tension region in the concrete section. Compared to reinforced concrete, prestressed concrete requires a smaller section of concrete, since the whole cross section is in compression and active. However, prestressing concrete needs the use of high strength steel wire which is extremely costly. The use of prestressing concrete may be carried out using minimization on the use of such expensive high strength steel. In this research, two methods of minimization of the use of high strength steel, which are the shifting of the support of the beam to get the smaller field moment. The other method is to reshape the concrete section to have a higher moment of inertia. It is found out that the two methods perform well in the minimization process of construction cost of the prestressing concrete beam.]]>

<![CDATA[KRL is a public transportation system is in the great interest of the Indonesian because it is considered effective and efficient for the community and can be a solution to streamline the mobility of the population, especially for the populace in the Jabodetabek region. As the number of passengers increases every year, it is important to know the services and facilities provided by the operator. This research aims to determine the quality of services and facilities of this transportation mode, both at the station and during the trip. The study examines the KRL Commuter Line service between Cikarang and Sudirman, with Sudirman Station selected as a representative sample for analysis. The analysis is made in accordance with Regulation of the Minister of Transportation No. 63 of 2019, and the level of customer satisfaction is analyzed using the Important Performance Analysis/IPA method and Customer Satisfaction Index/CSI. The research indicates that the services at Sudirman Station comply with most of the minimum standards outlined in the regulation, however some facilities need to be provided such as full platform roof, customer work desk and elevator or lift for disable. While on the train, CCTV and first aid kit need to be installed. According to the IPA method, there are attributes of service that need to be enhanced on the primary priority scale: (1) the height/width difference of the station platform floor and the railroad floor; (2) seating facilities in the waiting room; (3) passenger service facilities such as work desks; (4) a special elevator (lift) for passengers using wheelchairs; (5) availability of a first aid kit in each train set; (6) space capacity to carry standing maximum of 1 m2Â for 6 people; (7) availability of CCTV in the train; and (8) punctuality of departure or arrival time. In addition, the CSI score for KRL Sudirman station's quality of service performance is 71.60%, indicating that customers are satisfied with the quality of service provided.]]>
