Abstract

The problem that occurred in the ABC Flats Construction Project in Banjarbaru was that the project land was quite narrow. So if there is a large scale accumulation of material waste and lack of material management it can result in delays in the construction process, especially the mobilization and demobilization of tools. The aim of this research is to determine materials that cause large waste costs and the factors that cause them, as well as possible strategies to minimize waste. The analysis method is carried out using Pareto, waste cost and fishbone analysis. Collecting data by means of observation and interviews or brainstorming on several similar projects. The results of the Pareto analysis (80/20) show that there are two materials that contribute large costs, namely iron and concrete. The material that has the potential to generate large waste costs in the ABC Kalimantan Flats Construction Project as of the 21st week is ready mix concrete. The contribution of waste value per square meter is 0.073 m3 with a waste cost of 0.003% of the contract value. Based on the fishbone analysis, it was found thst the factors causing waste are a narrow location, stacking of moving materials, workers placing material carelessly, length of reinforcement that is not uniform, simplification of the shape of the pile cap structure, use of tools that do not match their function, number of orders that do not match, the rest of the concrete in the mixer, workers fatigue. Strategies to minimize waste of iron-concrete and ready-mix concrete materials are providing guidance to blacksmiths and workers, making access to tool distribution, using tools according to their functions, utilizing residual concrete, analyzing linear programs or barbending schedules. These results become considerations and suggestions in reducing the project budget due to the impact of material waste.

Abstract

Kota Depok, located in the western part of West Java Province, has experienced rapid growth over the past few decades. This growth occurred alongside intense urbanization, industrial development, and population increase. Apart from the positive impact of economic growth and infrastructure development, this rapid development causes environmental damage and loss of green open land. This can impact air, water, and soil quality and threaten environmental sustainability. This paper systematically tries to inventory the factors involved in urban green spaces' sustainability with a structural approach using Cross-Impact Matric Multiplication Applied to Classification (MICMAC) software. Of the 12 factors analyzed, five have a strong level of influence and low dependence, and 3 have a strong influence but have high reliance. These factors are 1) LU policy, 2) law enforcement, 3) environmental education, 4) stakeholder integrity, and 5) community involvement and participation, while 1) biodiversity conservation, 2) land value, and 3 ) environmental maintenance and protection is a factor that has a strong influence but is also highly dependent. Stakeholders can use the results of identifying these key factors as considerations for making decisions.

Abstract

High-density concrete (HDC) has been extensively employed as radiation shielding owing to its high density and capacity to absorb gamma rays and neutrons. The optimal average density of HDC for protecting against various types of radiation generally ranges from 2.2 g/cm³ to 3.5 g/cm³. This density may vary depending on the type of aggregate used, such as serpentine, barite, siderite, magnesite, and others. The study analyzes the use of high density concrete as a radiation protector using systematic literature review. The research method uses the PRISMA methodology with data search using the Publish or Perish (PoP) application with the keywords "High-Density Concrete," "Materials," and "Radiation Shielding" on the Scopus database. Bibliometric analysis using VOSviewer visualizes relationships between key terms in research. The results show that the average optimal density on high density concrete for radiation protectors varies, depending on the type of aggregate used.The selection of aggregates has a significant impact on the performance of concrete in radiation protectors. Aggregates such as barite, hematite, magnetite, and industrial waste (such as CRT glass and EAF barrel) are effective in enhancing radiation protection performance. Overall, the compressive strength of high-density concrete is an important factor in ensuring structural stability and effectiveness as a radiation shield. This study provides an in-depth perspective on the development of high-density concrete as radiation shielding and offers directions for future research in this field.

Abstract

As an area develops, developments in all areas of construction become increasingly widespread, including the construction/improvement of road construction. In the implementation of construction projects, problems often occur, one of which is that there is still a lot of remaining material that is wasted and will cause waste (Lestari, 2022). This research aims to identify and categorize the types of materials that cause waste in road construction, as well as evaluate the percentage, causes and impact of waste on project losses. Quantitative methods are used to obtain the percentage of waste on projects using data on material type, installation volume, purchase volume and total material costs. Then the data is processed using multiple regression analysis which will be simulated in SPSS. The analysis results indicate that the types of materials most frequently contributing to waste in rigid pavement road construction/improvement projects are as follows: X1 ready-mix concrete 10.99%, X2 wiremesh iron 6.73%, X3 dowel iron 11.81%, and X4 plastic 5.11%. The sources causing the generation of waste materials include design, implementation, material procurement/handling, and residuals. Assessing the impact of waste materials on losses in road construction projects using SPSS multiple linear regression, the project loss variable is derived as Y = -711.522 + 0.749 X1 + 60.096 X3. This implies that the materials significantly affecting project losses are X1 ready-mix concrete and X3 dowel iron. The magnitude of the influence of independent variables (ready-mix concrete and dowel iron) on project losses is 58.80%. The results of this research have implications in preventing losses from road construction projects in DKI Jakarta.

Abstract

One of the strategic issues facing the City of Sungai Penuh is flooding, as indicated by the Detailed Spatial Planning (Rencana Detail Tata Ruang or RDTR) for the years 2021–2024. Despite efforts to manage the drainage, there is currently no digital-based drainage asset database in the City of Sungai Penuh. The aim of this study is to optimize the asset database used by the Geographic Information System (GIS) at the Public Works and Housing Agency (Dinas PUPR) of Sungai Penuh. The objective is to enhance the efficiency of asset management owned by the Dinas PUPR of Sungai Penuh in terms of utilization, management, and maintenance. This research employs the waterfall method for system design and part analysis to evaluate the condition of the asset database. According to this study, the drainage infrastructure asset database system still does not meet user needs from various perspectives. Several aspects require improvement. The development of a drainage infrastructure asset database through the implementation of a Geographic Information System (GIS), aligned with findings from questionnaires and analysis using the PIECES framework, has proven to meet user expectations. This is particularly evident in the aspects of delivering relevant information, data security, and the availability of adequate services. This evaluation can be substantiated through the average Satisfaction Response (RK) score, which indicates user satisfaction levels ranging from satisfied to very satisfied.

Abstract

Tanjung Setia Beach is located in the West Coast area of Lampung Province. This location is very vulnerable of disaster such as tsunami, because it is on the edge of a geologically active continent with a coastline facing the Indian Ocean and distinguished by the confluence of tectonic plates. With such conditions at any time a tsunami disaster can occur and cause damage to the area. One of the weaknesses in the Tanjung Setia coastal tourist area on, West Coast of Lampung Province, is non exist of hazard maps or KRB (Disaster Prone Vulnerability) maps made by the National Center for Volcanology and Disaster Mitigation. Modeling the propagation of tsunami waves by determining the distribution pattern of tsunami waves and implementing several planned wave height values and historical wave height is a basic step of disaster mitigation in the area. Using Delft3D 4.04.01 software based on data and scenario analysis can produce wave propagation in the area. The height and wave period of the plan are calculated using the hindcasting method and are based on the SPM 1984 standard and then used as input in Delft3D modeling software. From the calculation results, the height and wave period of the maximum plan for the 15 year is 3.01 m with a period of 8.21 s, the 25 year is 3.16 m with a period of 8.49 s and the 50 year is 3.37 m with a period of 8.87 s. In addition, historical tsunami wave heights of 3.6 m, 8 m and 15 m are also used as inputs in the Delft3D model. The results of propagation planned wave does not cause a significant tsunami disaster. As a result of wave propagation based on the historical height of tsunamis used, 3.6 m wave does not cause tsunami disasters in the area and take 35 minutes to reach coastal areas, while waves of 8 and 15 meters are able to cause tsunami disasters on land, which takes 27-34 minutes to reach the coast. All three scenarios qualify for model accuracy in shallow seas. From the results of mapping using GIS software, the maximum propagation of the scenario of high waves of 8 meters on land as far as 803 meters and waves of 15 meters as far as 872 m from the coastline.

Abstract

PT X, a company operating in the Fast Moving Consumer Goods (FMCG) sector located in East Jakarta, is expanding its Distribution Center (DC) to help increase distribution rates. Selecting the right contractor can help expedite the supply chain and shape the company's strategy. PT X faces several issues related to contractor selection with various criteria in the DC construction process. To address these issues, careful contractor selection is necessary. Multi-Criteria Analysis (MCA) methods such as Simple Additive Weighting (SAW), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), and Multi-Attribute Utility Theory (MAUT) are used in the contractor selection system. The SAW and MAUT methods have advantages in simple and easy calculations, while TOPSIS excels in detailed data processing. This study aims to compare these three methods in contractor selection for the DC construction tender. The research data were obtained through questionnaires and interviews with stakeholders and PT X management. The analysis results show that, based on Euclidean Distance (ED) and Average Error Rate (AER), the MAUT method is considered more suitable for application at PT X, with an ED value of 0.4012 and an AER of 0%.

Abstract

Walking is the simplest form of transportation and can be used by everyone. The decline in the desire to walk is associated with the reduced service functionality of sidewalk infrastructure. This study examines pedestrian perceptions regarding the service functionality of sidewalks on DR. Ratulangi, AP. Pettarani, and Gatot Subroto streets in Banggae Subdistrict, Majene Regency. The perception assessment study uses a qualitative and quantitative descriptive statistical approach, referring to the Ministry of Public Works and Housing Regulation No. 03-2014, which provides guidelines for planning, providing, and utilizing infrastructure and pedestrian network facilities in urban areas. The analysis results indicate that the use of sidewalks is mainly driven by considerations of time and safety while walking. Respondent perceptions show that the aspects of comfort, safety, and connectivity on the streets studied fall under the "fairly good" criteria. Based on the existing perceptions, respondents expressed a desire for improvements and enhancements in these variables, which are expected to increase both interest and the need for walking using sidewalk facilities.
