Abstract

Depok City is an area undergoing significant changes in land cover due to rapid urban development. Additionally, population growth is contributing to these land cover changes. These factors exert pressure on land use changes, with implications for land cover. Therefore, it is necessary to conduct a spatial analysis of land cover changes in Depok City. This research employs Geographic Information System (GIS) methods and spatial analysis to examine land cover changes in Depok from 2017 to 2022. The objectives of this study are to identify the land cover conditions in Depok from 2017 to 2022 and analyze the changes in land cover during this period. The data source used is Landsat 8 satellite imagery. These satellite images were interpreted to produce land cover maps for the years 2017 and 2022. Subsequently, these two maps were overlaid to assess changes in land use. The research results revealed seven land cover classes in 2017, with the largest in terms of area being Residential/Built-up Areas (12,383.43 hectares), Green Open Spaces (3,479.66 hectares), Dryland Agriculture (2,218.65 hectares), Services/Industry (885.41 hectares), Paddy Fields (414.59 hectares), Open Land (373.66 hectares), and Water Bodies (239.23 hectares). Spatial analysis indicated a decrease in land cover for Green Open Spaces (238.84 hectares), Dryland Agriculture (122.67 hectares), and Paddy Fields (31.89 hectares). Conversely, an increase in land cover was observed for Residential/Built-up Areas (266.01 hectares), Services/Industry (91.84 hectares), and Open Land (35.55 hectares).

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

Landfill in road projects requires a stable condition before it can be continued on further work. The stability factor of the landfill depends on the bearing capacity of the subgrade, the shear strength of the soil, the planned elevation, and the angle of inclination of the landfill. This research is located on one side of the Jagorawi Toll road and the Bogor Outer Ring Road, near the South Sentul Toll exit gate. The results of the soil investigation obtained a clay type soil classification at a depth of 0 – 13 m (N-SPT value 3-5). Initial analysis shows the need for landfill height, varies along the road (ranging 4.9 m - 2.4 m). The purpose of this research is to compare the stability of the landfill in the following 2 conditions, 1st condition from STA 1+789 – STA 1+850 (4.9 m height of landfill) using Corrugated Concrete Sheet Pile (CCSP) reinforcement on the left and right of the road side with a 2 m deep geotextile layer, and 2nd condition from STA 1+850 – STA 1 +950 (2.4 m height of landfill) does not use any reinforce. The research approach uses quantitative descriptive, research data including other soil classifications, bor logs, N-SPT values, soil properties from samples (C, Ø, γ, etc.) taken from the site. Apart from that, data on the geotextile and CCSP parameters that will be used is also needed. Analysis was carried out using the Finite Element approach and Plaxis 2D V22 software. The results show that in 1st condition, the safety factor value is 3.7, where the reinforcement system provided is able to withstand 3.7x the working load (vehicles and active soil). Meanwhile, on the 2nd condition produces a safety factor value of 5.2. The analysis results show that these 2 areas have a safety factor that exceeds the existing literature requirements, namely 1.5.

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

Sustainable buildings generally demonstrate a friendly environment, save energy and reduce operational costs, thus opening up significant investment opportunities in green buildings of the office property type. It is a shame that currently there are still very few office building developers who apply the green building concept, meanwhile the green building concept provides 31% greater profits than conventional buildings. This study aims to analyze the financial feasibility of four office buildings which are divided into two categories, namely category one (building 1 and Building 3) with a grade A building type and category two (building 2 and building 4) with a grade B building type. Building 1 and building 2 has received green building certification issued by GBCI. Building 2 and building 4 are buildings with a conventional concept. Calculation analysis is carried out using the Net Present Value (NPV), Internal Rate of Return (IRR) and Payback Period (PP) methods. Based on the results of the analysis, from the two categories of building types, the results showed that the NPV of each building was said to be financially feasible with an NPV ratio of 294% (category 1) and 162% (category 2). The IRR obtained exceeds the MARR value, with a comparison of 54% (category 1) and 21% (category 2). The payback period is less than the project investment period, namely 20 years, with a difference of 5 years (category 1) and 3 years (category 2). The office buildings with the highest and best NPV are Building 1 and Building 3 (category 1), so that even though the construction costs and green building design planning costs incurred are higher, in the research object of each building there are quite significant differences in NPV and IRR and It is hoped that all new construction and renovation work carried out by developers can apply the green building concept.

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.
