Abstract

During the current administration, the construction sector, especially toll road infrastructure in Indonesia, has increased. This will increase the amount of cement production to meet construction needs. Even though the cement industry is one of the contributors to gas emissions. In addition, the plantation sector can be optimized as an alternative construction material. Such as palm shell waste (POFA), which contains the same content as cement. The fisheries sector can also be optimized as an alternative construction material. such as green mussel shells which have the same content as cement, which is pozzolanic. Based on these problems, the purpose of this research is to optimize palm oil shell waste and green mussel shells as cement substitution materials in CTB to reduce gas emissions. The method used is research and experimentation by partially substituting cement by 10% and 20% using POFA. 5% and 10% use green mussel shell waste which will later be compared with the CTB Job mix formula which complies with the general specifications by testing the compressive strength of concrete and analysis of CTB work unit prices per 1 m3. The results of this study revealed that the highest compressive strength of 5.5 MPa occurred in 20% POFA substituted CTB and 10% green mussel shells. This compressive strength is higher than Normal CTB. However, from the results of price analysis it can be seen that 20% POFA substitution CTB and 10% green mussel shells require a 3.7% higher cost than the Normal CTB price or a difference of Rp.19,792.22.

Abstract

Indonesia's increasing population is a crucial problem. According to the Central Bureau of Statistics (2021), Indonesia's population growth in 2020 will increase by 32.56 million people. In line with the need for housing in Indonesia, as a result the available land is decreasing, so many housing developments use partitions. However, partitions on the market still have many drawbacks. Utilization of pineapple leaf fiber as a substitute for fiber and blood clam shell waste as a substitute for cement is certainly a solution to this problem. Where pineapple leaf fiber has a carbon content such as 23.39% cellulose, 42.72% hemicellulose, and 4.03% lignin. Blood clam shells contain Sio2 of 8.252% and CaCO3 ranging from 66-98%. The purpose of this study was to determine the effect of the use of these two materials on the partition characteristics produced through physical tests and mechanical test. Samples were made in laboratory studies with variations of pineapple leaf fiber subs 0%;30%;70%;100% with the number of samples for each mold size being 3 samples. Through the results of tests that have been carried out, the best variation of pineapple leaf fiber substitution is the 70% variation. This test was also carried out by comparing several commercial partitions (gypsum, kalsiboard and GRC).

Abstract

In the Grand City Balikpapan area, a residential area is planned using a WTP (Water Treatment Plant) system for clean water supply. The project is planned to be completed in 12 weeks, but there is a delay in the project work so that it requires acceleration. The required objective is to optimize the time and cost in the implementation of the acceleration project and get a method or alternative that is in accordance with the project acceleration plan. The methods used in the acceleration of the Grand City Balikpapan WTP Area Landslide Handling Work Project in order to obtain the optimal time and cost are methods called Time Cost Trade Off and Fast Track. In Time Cost Trade Off method, there are three acceleration alternatives used, namely additional working hours, additional labor and additional heavy equipment. The acceleration time obtained based on the methods and alternatives used is 60 working days. The cost needed to complete the acceleration project by using Time Cost Trade Off method on the alternative of additional working hours (overtime) is Rp 664,593,423, while on the alternative of additional labor is Rp 644,856,028. The alternative of adding heavy equipment cannot be used in accelerating this project because the scope of the project is small for the use of a lot of heavy equipment. Then for the Fast Track method, it costs Rp 611,609,685, so the method used to accelerate the project is the Fast Track method by changing the working relationship.

Abstract

The dwindling availability of land has resulted in an increase in the price of residential houses every year, moreover cities with relatively denser populations have an increase in house prices of more than 20% each year. The design of residential houses by utilizing used containers will save material, transportation, and construction costs, so it is hoped that this alternative can be developed to become a sustainable solution. The research was conducted by designing a 2-storey container house with a building area of 172.8 m2 using the SketchUp2022 software and then calculating the estimation cost analysis. The results of the estimation costs show that conatainer house needs cost of IDR 565,476,007.90 or IDR 2,827,380.04/m2 included tax.  So that container house can savings of 19.22% - 43.45% when compared to the average price of conventional houses in Indonesia of IDR 4,500,000.00 - IDR 6,000,000.00 per m2 .

Abstract

In a construction project, the use of partition walls can cost quite a lot due to the high cost of raw materials used in partition walls. But unfortunately in the manufacture of GRC boards still use materials that are not environmentally friendly such as fiberglass (fiber fiber). Coconut fibers were used as additives because they have high tensile strength, while bagasse ash is used as a cement substitution to reduce production costs as well as help in reducing the amount of sugar industry waste. This study aims to find out the best mixture variations, density, water absorption,bending strength, hitting firmness, and price comparison. In this study, comparing conventional GRC Board with 3 variations of coconut fiber substitution mixture of 10%, 20%, 30% and bagasse ash 2.5%, 5%, 10% with a total of 48 samples and sizes for constancy tests at 20 cm x 20 cm x 0.6 cm and for flexural strength tests with a size of 10 cm x 10 cm x 0.6 cm. Mechanical testing based on SNI-01-4449-2006. The results of the test proved that the optimal mixture is in GRC Board D (30% coconut fiber and 2.5% bagasse ash) because it can produce better flexural strength and firmness than conventional GRC Board and GRC Board with bagasse ash and coconut fiber is 18% cheaper than conventional GRC Board.

Abstract

Abstract: Despite the fact that lean construction (LC) has been shown to increase construction safety, little research has been done been carried out to investigate how LC technology can be applied to safety management. This the study aims to close this gap by developing a safety planning and control (SPC) process based on LC technology and evaluate it using a structural equation model. The process is based on the final planner system research framework (LPS) and consists of four sub-systems (ie, analysis layer, planning layer, control layer, and performance layer). Data was collected from 150 projects HSE employee at building construction in the Jakarta area. These findings will serve as a guide for construction stakeholders looking to improve efficiency safety management by incorporating some LC technology into the SPC process. And four subsystems work together to create a positive circulation system that aids long-term improvement construction safety management.

Abstract

The urban center of Batam faces recurrent water crises. The introduction of the Bengkong Sadai Wastewater Treatment Plant (WWTP) offers a potential solution, converting domestic wastewater into reusable water, thereby addressing scarcity concerns. This research provides a comprehensive SWOT analysis of the WWTP, aiming to understand its potential for ensuring sustainable water management in Batam. We identified that while the WWTP capitalizes on state-of-the-art infrastructure, making a notable contribution to water reclamation and organic fertilizer production, it also confronts challenges like community engagement and operational complexities. Based on the analysis, the study emphasizes the criticality of proactive maintenance, robust stakeholder collaboration, and the need for a forward-thinking approach. This work sheds light on Batam's endeavors and offers a blueprint for other urban locales grappling with similar challenges.

Abstract

Flood mitigation of Situ Pondok Jagung caused by it’s inadequate capacity to handle water, resulting in overflow and localized inundation, this study employed an analytical and simulation modeling approach using SWMM 5.1 software. The modeling process required input data such as Rain Gage, Subctachment, Conduit, Juction, Storage Unit, and Outfall. The analysis and modeling revealed a capacity shortfall, evident from the floodwater levels observed in Situ Pondok Jagung. The analysis and modeling results indicate an excess capacity of the storage capacity, as evidenced by the flood water elevation in Situ Pondok Jagung. Thus, the hydraulic analysis in SWMM 5.1 considers two design conditions: the existing condition with a height of 1.5m, showing a total water discharge of 103,75 m3/s, and a storage volume of 119.250 m2. For the planned condition using trial and error experiment, dredging was performed to a depth of 20cm, and an additional 50cm in height was added to the levee. As a result, the height of Situ Pondok Jagung became 2,2m, with zero overflow, and a storage volume of 174.900 m3. This represents a reduction of 40% and indicates that this planning effort could be considered as an alternative solution.

Abstract

As the construction industry in Indonesia continues to grow, it has significantly impacted the demand for building materials, particularly in the construction sector. One such material is "batako," which is used as a wall filler, along with cement as a bonding material (grout). Therefore, there is a need for a solution that provides easier workability during installation and is cost-effective. The objective of this research is to innovate and analyze the design of triangular-shaped batako with an interlocking system on each side. The methodology used involves experimental testing in a laboratory and follows the Indonesian National Standard (SNI) 03-0349-1989. The process includes material testing, specimen production, compressive strength testing, absorption testing, and a cost comparison analysis. The research resulted in the development of "trilock brick," a triangular-shaped batako measuring 36 cm in length and 9 cm in thickness. The average compressive strength at 28 days was 9,487 MPa, with an average water absorption rate of 5.344%. The installation cost per 1 m2 was Rp. 76,802, with a grout thickness of 0,5 cm. This research demonstrates that this innovation possesses compressive strength and water absorption values comparable to conventional batako. Additionally, trilock brick offers economic advantages with a cost difference of up to 13% compared to conventional batako requirements.
