Abstract

The construction of subsidized housing projects continues to increase every year. This development must be in line with the benefits received by developers of subsidized housing, especially regarding investment costs, which need to be analyzed for suitability based on the benefits obtained. The developers need to make a decision in allocating the amount of funds they currently have, with the aim of gaining profits and increasing that value in the future. The technical aspect determines that the developers have carried out development in accordance with the standards set by the government. Analysis of housing investment needs to be carried out, including from the technical and financial aspects, to find out how much benefit has been obtained from the housing business that has been going on so far. The review of the technical aspects includes the height of the subsidized house building, the Basic Building Coefficient (BBC), the Building Floor Coefficient (BFC) and the accessibility of the location. Furthermore, the analysis of financial aspects using the Net Present Value (NPV) and Benefit Cost of Ratio (BCR) methods. From the results obtained, the construction of Mutiara Residence II Housing in Aceh Tamiang Regency has met the requirements from the technical aspect with a building height of 15 m, BBC and BFC 30% as well as accessibility close to the city center, offices, houses of worship and health centers, with mileage less than 10 minutes. The feasibility of the financial aspect is calculated using the NPV and BCR methods with NPV 0 and BCR 1, so the cash flow for proper investment and meets to be implemented for the development of subsidized housing development. The return on investment obtained ranges from 8% to 10%. From the results of the projection for the development of subsidized housing development using sensitivity analysis, an addition of 20% was carried out on certain elements, it was found that from a financial aspect it was still adequate and feasible to add 20% with the selling price in accordance with government regulations which increased every year.

Abstract

Increasing the use of space in the multi-storey buildings is self-requirement for the owner in making the most of function of the building. The Langsa City Hospital Operating Building with structural height of +10 meters and has two floors, with the existing part of the 2nd floor not fully designed a closed room. Currently, according to the owner's request, the function of this building is being utilized to be used as a first-floor room as an operating room, while the second floor is intended as a storage room and hall. Based on that, it is necessary to estimate against the appropriate and efficient method of slab work so that to be sure the project objectives are achieved. This paper aims to analyze the comparison between the use of steel deck and conventional deck to the study sites based on cost and time. The research method used begins with collecting field data, calculating the budget plan referring to the Work Unit Price Analysis (AHSP) contained in the contract document, then estimating the implementation time using the labor coefficient according to the 2016 AHSP. The results showed that there was a difference in the budget for the two deck slabs of Rp. 28,616,000. In addition, in terms of the duration of the completion of the work, the difference between the calculation of the estimated implementation of the conventional deck work and the realization of the implementation of the steel deck is 39 working days. Based on the results obtained, the use of steel deck is cheaper and more time efficient than the use of conventional deck. So that the selection of the use of steel deck at the study site is appropriate because it can save costs and time.

Abstract

Abstract Residual construction material is defined as something that is more than what was planned, both from the results of the work and the remaining, damaged, or lost material so that it can no longer be used according to its intended purpose. From the results of observations that have been made in several subsidized housing locations in Langsa City, there are many leftover materials from architectural work, because of that it is necessary to do an analysis of the type of waste material, the causes of waste and waste prevention measures that are often carried out. The method in this study uses descriptive statistical methods using Kendall's W so that rankings are obtained for variables, types of waste material, factors that cause waste, and waste prevention actions that are often carried out. The results of this study, the type of material that has the largest quantity is sand with a total score of 97, cement with a total score of 93, and red brick with a total score of 45. The dominant factor causing the amount of remaining architectural work material in subsidized housing is external factors with a total score of 116, material management with a total score of 83, and workers with a total score of 80. Then the form of preventive action that can minimize the waste of material that is often done is checking periodically (monitoring) with a total score of 125, purchasing materials as needed with a total score of 125, and increased coordination between workers with a total score of 124.

Abstract

The construction of subsidized housing in Langsa City has increased, yet it fails to bridge the gap between housing demand and supply, especially in metropolitan areas. To ensure the development of subsidized housing benefits the community, careful attention is required. This study aimed to identify the most suitable area for subsidized housing and its requirements in Langsa City. Using the Analytical Hierarchy Process (AHP), the study assessed five criteria: accessibility, facilities and infrastructure, environmental conditions, buildings, and subsidized house prices. The AHP findings achieved a consistent index of 7%, meeting the required threshold. Results revealed that accessibility holds the highest weight (0.33), followed by facilities and infrastructure (0.20), environmental conditions (0.19), building conditions (0.17), and house prices (0.11). This highlights accessibility as a significant factor in purchasing subsidized housing in Langsa City. Langsa Barat District emerged as the best-fitted location for subsidized housing, with a weight value of 4.09. Despite increased construction efforts, addressing the housing demand and supply gap remains a challenging task in Langsa City's metropolitan areas.

Abstract

Pelaksanaan proyek konstruksi pada pembangunan Gedung Laboratorium Dasar Universitas Samudra mengalami perubahan desain karena penyesuaian kondisi dan kebutuhan lapangan sehingga terdapat deviasi jadwal pekerjaan antara rencana dan pelaksanaan pada proyek tersebut. Untuk mencapai target sesuai jadwal dan menghindari keterlambatan dapat dilakukan percepatan. Penelitian ini bertujuan untuk mengetahui waktu dan biaya yang diperlukan untuk percepatan melalui penjadwalan ulang. Pendekatan Time Cost Trade Off digunakan, dengan mempertimbangkan opsi seperti lembur dan tenaga kerja tambahan. Berdasarkan temuan penelitian dan perhitungan, penambahan jam lembur 4 jam per hari dapat mengurangi waktu penyelesaian proyek dari yang direncanakan 32 hari menjadi 23 hari dan mengalami peningkatan sebesar 7.294.194.057,00 sedangkan pada penambahan tenaga kerja sebanyak 41 orang dapat diselesaikan dalam kurun waktu 25 hari dari 32 hari rencana penyelesaian proyek dan mengeluarkan biaya lebih sedikit yaitu Rp.118.314.967,00. Sehingga pemilihan metode Time Cost Trade Off yang lebih efektif untuk penyelesaian proyek adalah penambahan tenaga kerja.
