Abstract

Earthmoving work is often performed based on simple calculation and experience. This practice may work on a small project. However, for a big project in which a large excavation volume must be accomplished, managing the work become more complex. Some different equipment in various types and sizes need to be assigned. Project managers should determine the best combination of equipment with the correct amount to achieve a satisfactory result. This research was conducted to optimize the productivity-cost index in earthmoving works using a discrete event simulation (DES) analysis in four different schemes. An underpass project in Yogyakarta was used as the case study. The optimal combination of equipment was determined by the highest value of the productivity-cost index. The result shows that the highest productivity-cost index of 18.22 was achieved by the combination of four big excavators and 90 small trucks (2E4 90D1). It offered a better productivity-cost index compare to the contractor’s existing equipment combination which could only reach a productivity-cost index of 5.3.

Abstract

Bridge oftentimes become a critical components of roads because it used to determine the maximum load capacity of a passing vehicle on the roads. The bridges require maintenance activity in the shape of general maintenance or periodically replacement while this is estimated in order that the bridge may continue to function properly. The economic evaluation of the Interurban Bridge Management System (IBMS) aims to determine the priority of bridge handling. One of the calculations required in NPV and IRR calculations used in priority handling is the cost of replacing the bridge. Over time, the Interurban Bridge Management System (IBMS) system must be constantly updated to continue to use in accordance with current circumstances and use new, better methods. This study uses Life-Cycle Cost (LCC) method as an alternative method to calculate the replacement cost of 5 bridges in Daerah Istimewa Yogyakarta in 2012. The IBMS method produces a priority sequence of bridge handling with Bogo bridge, Suru bridge, Winongo bridge, Kalasan B bridge and Duren bridge in sequence. The Life-Cycke Cost (LCC) method produces a priority sequence of bridge handling with Bogo bridge, Winongo bridge, Suru bridge, Kalasan B bridge and Duren bridge. The average initial cost of bridge replacement using both methods is 23.012%. The value earned using the Life-Cycle Cost method is always greater due to the addition of inspection fees, maintenance costs, and damage costs of the bridge.

Abstract

 ABSTRACTMany factors  influence developers to determine proce of a house unit of housing. There are some additional costs must be considered for accomplishing projects which not directly related to the cost of a house units. These costs are needed to provide basic and supporting facilities, utilities and some other project overheads are then borne to prospective customers. This study observed the influence of those costs to the cost of building units of luxury housing in Yogyakarta. The survey was conducted to find the cost components from two luxury housing projects. The data was obtained through interviewing field supervisors and heads of engineering which consisted of the costs for developing public and residental facilities, expensing projects overhead, land acquition and house construction. The results showsed that in average, cost of facilities, infrastructure, utilities and project overhead of both housing affect about 29,9% of the total, it also shows that land acquittion for road construction became the highest influenced cost. Keywords: basic facilities, effect,overhead, supporting facilities, utilities  ABSTRAK Banyak faktor mempengaruhi pengembang perumahan dalam menentukan harga tiap unit rumah. Selain biaya dasar unit rumah, terdapat beberapa biaya tambahan yang tidak langsung berhubungan dengan biaya pembangunan unit rumah seperti, biaya bahan, alat dan tenaga kerja namun harus dipersiapkan untuk mendukung pelaksanaannya. Biaya-biaya tersebut seperti biaya untuk pemenuhan keberadaan prasarana, sarana, utilitas dan overhead yang pada umumnya kemudian dibebankan kepada pelanggan yang membeli setiap unit rumah. Studi ini membahas pengaruh keberadaan biaya-biaya tambahan tersebut terhadap biaya produksi unit bangunan pada perumahan mewah di Yogyakarta. Survei dilakukan pada dua perumahan mewah di Yogyakarta. data diperoleh melalui wawancara dengan supervisor lapangan dan kepala teknik yang berupa biaya pengembangan fasilitas umum dan fasilitas sosial perumahan, overhead, pengadaan lahan dan biaya bangunan. Hasil penelitian menunjukkan bahwa secara rata-rata pembiayaan fasilitas, infrastruktur, utilitas dan overhead terhadap biaya unit bangunan pada kedua perumahan berpengaruh sebesar 29,9% dari total biaya yang diperlukan, dimana biaya pengadaan tanah untuk prasarana jalan menyumbangkan kontribusi terbesar dalam pembiaayaan tersebut. Kata kunci: biaya, pengaruh, perumahan, overhead

Abstract

Abstrak Permasalahan konstruksi tidak jarang menjadi indikator adanya penyimpangan perilaku pihak-pihak yang terlibat dalam suatu proyek konstruksi termasuk penyimpangan tindak pidana korupsi. Tingginya kasus korupsi pada pengadaan dan pelaksanaan proyek konstruksi menjadi latar belakang dilakukannya penelitian ini. Telaah mendalam terhadap permasalahan dan penyimpangan yang menjadi dasar putusan hakim dalam memutuskan kasus konstruksi menjadi kasus korupsi merupakan tujuan dari penelitian ini. Data yang digunakan berupa putusan-putusan kasasi kasus korupsi diperoleh dari laman repositori Mahkamah Agung. Hasil kajian menunjukan bahwa umumnya permasalahan dan penyimpangan yang terjadi pada kasus korupsi proyek konstruksi adalah berupa hasil-hasil pekerjaan yang tidak sesuai dengan kontrak, baik secara kualitas maupun kuantitas, yang pada akhirnya penyimpangan tersebut diputuskan sebagai perbuatan melawan hukum oleh hakim. Pejabat pemerintah dan/atau penyedia jasa yang menangani proyek menjadi pihak yang dianggap lalai atas terjadinya penyimpangan yang mengakibatkan kerugian negara sehingga dinyatakan telah melakukan tindak pidana korupsi meskipun bentuk umum tindak pidana korupsi tidak selalu terdapat di dalamnya. Berdasarkan kajian terhadap 18 putusan kasus korupsi, hanya terdapat empat kasus yang mengadung tindak pidana korupsi berupa tindakan suap-menyuap, pemerasan dan benturan dalam kepentingan, serta 14 putusan lainnya secara umum berupa ketidaksesuaian pekerjaan dengan kontrak yang kemudian juga dikategorikan sebagai bentuk tindak pidana korupsi. Kata-kata kunci: Permasalahan konstruksi, penyimpangan proyek, kasus korupsi, putusan Mahkamah Agung, kerugian negara. Abstract Specifications unfulfillment frequently becomes an indicator of construction project deviations, including corruption. The high number of corruption cases in the procurement and implementation of construction projects is the background for this research. To dig in-depth knowledge of the circumstance, we carried out a study to find the issues and deviation in the implementation of construction projects which wew used as the basis for the judge’s decision. We obtained data on the corruption of construction projects from cassation decisions on the Mahkamah Agung repository page. The result shows that, in general, the deviation issues occurred due to the differences between implemented works and the contract, which the judges considered them as unlawful acts. The staff of government representatives who in charge of handling the project and or person in charge of the construction providers subsequently became a party deemed negligent of such deviations and state losses. They are declared to have committed a criminal act of corruption even though there is not always any direct evidence of general forms of corruption. Study of 18 supreme court decisions, we found that there were only four cases were proven to contain corruption in the chronology of the verdicts: an act of bribery, extortion, and conflicts of interest and 14 other were generally in the form of a work inconsistencies with the contract which was later also categorized as corruption. Keywords: Construction problems, project deviation, corruption cases, supreme court decisions, state losses.

Abstract

The increasingly high development in Indonesia has spurred the number of construction service companies to increase. On the other hand, the increase in the growth of construction service companies has not been accompanied by a good atmosphere of construction implementation. As a result, delays in completing work have become commonplace in construction projects in Indonesia, the eastern part, and especially Papua. This research investigated the factors causing delays in completing construction work in Papua Province, especially in Merauke Regency. Questionnaires were distributed to contractors registered as members of GAPEKSINDO and domiciled in the Merauke district. The purposive sampling technique took the number of samples. The data analysis in this research used a Non-Parametric Statistical Test with Kendall's W analysis using SPSS 25.0 for the Windows program. The seven main factors that cause construction project delays are related to consultants. The test results show that the main factor of delay in construction projects in the Merauke Regency is the labor factor, with a mean rank value of 2.56. Factors that do not affect construction delays are other factors with a mean rank value of 5.28.

Abstract

Building Information Modeling (BIM) and Geographic Information systems (GIS) are two digital system innovations advantageously applied in the Architecture, Engineering, Construction, and Operations (AECO) sectors. GIS and BIM integration development is indispensable in building and infrastructure management. This integration promises several benefits for the operational phase of buildings and infrastructures. However, it faces challenges in data transformation and collaboration. This study proposes a framework and model for a web-based building management platform. The framework is developed by transforming BIM data into the GIS environment using the latest technology from ArcGIS. It allows data-sharing and collaboration among stakeholders, help build management, and is valuable for decision-making. The stakeholders, who do not need a BIM-GIS expert, could virtually see the report and updates of this building model every time.

Abstract

The increasing population growth rate causes a city to face the problem of limited land for residential development. Housing is a fundamental demand of the community that must be fulfilled, especially for low-income people. Through the construction of flats named Rusunawa, the government tries to fulfill the demand for decent housing and anticipates the emergence of slum settlements. In its development, there are Rusunawa whose management is not optimal in maintenance which results in unkempt conditions and causes residents to not get satisfaction and convenience in occupying housing. This study aims to analyze the level of satisfaction, the convenience of residents, and the management of Rusunawa. It is based on the income level of residents and identifies strategies for service improvement of Rusunawa management. This study uses primary data to obtain the level of satisfaction, comfort, and management of flats based on income levels. The data collected is preliminary data consisting of data from questionnaires to the residents of the apartments and data from interviews with the Rusunawa management agency. The method in this study uses a mixed method based on qualitative methods with interview techniques and quantitative methods with survey techniques (questionnaires). The results show that there is a significant difference in the level of building convenience based on the income level of the residents of the Rusunawa. The management of the Rusunawa has not reached its maximum goals related to implementing the Rusunawa regulation. Runaway development programs are required, such as providing counseling, participating in social activities regarding environmental care, and conducting socialization with residents, especially the priority aspects of unique flats for low-income communities.

Abstract

The success of the construction sector is inseparable from cost and quality, it is reported that identified quality failures reach 5-20% of the project contract value. To reduce quality failures and failure costs in the implementation of construction projects, it is necessary to provide cost of quality (COQ) assistance. In this research, reinforced concrete construction was chosen as the object of COQ assistance because it is a critical part of the structure. The purpose of this research is to categorize the COQ from internal and external factors and analyze the potential costs incurred for these failure factors. Analysis of the cost of quality failure was carried out based on the weighting of the results of the pairwise comparison matrix to obtain consistency index (CI) and Consistency ratio (CR) values and using the Kruskal Wallis test as a non-parametric test approach. The results of this research indicate that COQ greatly influences profitability, where the failure of the highest internal quality is the work method factor which affects the failure of the final concrete result in the form of structural and visual defects, while the highest external quality failure is the product selection factor at the client's request which causes the resulting construction products are not in accordance with the specifications or not in accordance with the expected function. Based on the causal factors of the quality failure, the implementation control process affects the result of product quality to the point of causing clients to demand, replace, and repair during the warranty period. Failure costs that affect the highest contract value amounted to 7.26% of internal failures and 6.40% of external failures.
