Indonesian society is currently experiencing a huge backlog in livable house. The backlog tends to grow in line with the conditions of insufficient supply and growing demand. In accordance with the government's program increasing the production of livable housing, human resources in the field of housing industry should be prepared well. One of the important human resources is the expert in the execution of housing constructions. The experts should have competences needed so that the construction can be executed efficiently and effectively. The objective of this study was to determine the sequence of critical competencies that should be mastered by the expert in execution of housing construction. This result is useful for improving the quality of education and training of human resources in the field of housing construction to overcome the backlog of livable house in Indonesia. The research method involves two main steps: the data collection and data processing methods. The competences and the important level were collected from the housing developers through interviews and questionnaires. The interview is intended to determine the types of competencies while questionnaire intended to determine the level of importance. The importance was validated with Kendal-W (Kendall's Coefficient of Concordance). The result shows two groups of competencies that should be mastered by the experts in execution of housing construction: 1. pre-construction phase, and 2. construction phase. In the pre-construction phase, the expert should master in: shop drawing, site plan for construction, budgeting/scheduling, workforce planning, mapping, health and safety issues, and the contract. While at the construction phase, the expert should master in methods of: scaffolding/formwork, reinforcement, roof framing, concreting, time/quality control, electrical/plumbing work, and material/equipment management.
For construction of million houses needed by Indonesians, material efficiency should be prioritized. This is because so many wasted materials in the process. For example, much mortar is wested on a masonry work. To minimize the waste, a mortar mold should be used. The objective of this study was to determine the efficiency that could be got by using a mortar mold in a masonry work. The reseach method was experiments. The result was determined by comparing the mortar needs between the two ways, i.e. with and without the masonry mold tool. Twenty-one experiments have been conducted for each way. The results of this study indicate that using of the tool could save about 23% of mortar or 23% of the material cost.
Eco-settlement infrastructure planning is a concept that puts the balance of the ecosystem at a settlement. This concept is urged to apply to residential areas, especially in the area of the catchment. Huntap as a settlement area also need to apply the concept of eco-settlement. After the eruption of Merapi, Huntap development is mostly done in the area of Cangkringan which is the catchment area that supplies water in the city of Jogjakarta. The purpose of this study was to report the results of the application of eco-settlement planning on huntap in Cangkringan area. The method used in this research are: 1) Identification of the condition of settlement infrastructure that had been built 2) comparative analysis of results of this identification with the concept of eco-settlement, 3) to formulate the results of the analysis. From the analysis, we can conclude that the development of infrastructure in the dwelling in accordance with the concept of eco-settlement.
Cost estimate is very important for all parties involved in a construction, such as owners, contractors, consultants, investors. A method for calculation of cost estimate is Budget Plan (RAB). However, the calculation requires some competencies and time. The objective of this study is to develop a easier method to calculate the cost estimation, i.e. by developing formulations of RAB based on the price of some materials. This research was carried out on simple house projects, which was built in 2014 in regions of Magelang, Bantul, Sleman and Yogyakarta. The data were collected by observation and interviews in the fields. The interviews were conducted to collect information of material prices and labor costs used as the independent variables. While, the observation aimed to calculate the value of RAB used as the dependent variable. Analysis of data used the correlation and regression techniques. Based on the analysis, the variables with strong correlation with RAB is prices of the brick (0.907), while the correlation between employee wage and RAB is quite low. The regression analysis resulted that the cost of house construction can be predicted by equations: RAB = 66,823 X1 - 1.277.771 or RAB = 53,244 X1+ 26,423 X2 -1.826.152, with X1 is the price of standard brick per hundred pieces expressed in rupiah and X2 is a prices of floor covering material per square meter stated in rupiah. Based on the validation, the accuracy of the formulations is over 97%. Estimasi biaya memiliki fungsi yang sangat penting dalam dunia konstruksi bagi semua pihak yang terlibat di dalam konstruksi seperti owner dan investor. Salah satu cara membuat estimasi harga tersebut adalah dengan menggunakan Rencana Anggaran Biaya (RAB). Bagaimanapun, cara perhitungan tersebut memerlukan kompetensi, ketelitian dan membutuhkan waktu yang cukup lama. Penelitian ini bertujuan mencari cara yang lebih mudah dan cepat untuk menghitung estimasi biaya, yaitu dengan mencari formulasi yang bisa digunakan untuk menghitung nilai RAB dengan variabel bebas harga bahan dan upah tenaga kerja. Penelitian ini dilakukan pada proyek-proyek rumah sederhana tipe 45, yang dibangun pada tahun 2014 di komplek perumahan yang ada di Kabupaten Magelang, Kabupaten Bantul, Kabupaten Sleman dan kota Yogyakarta. Pengumpulan data dilakukan dengan cara observasi dan wawancara langsung di lapangan. Wawancara dilakukan untuk mendapatkkan informasi harga bahan dan upah tenaga kerja yang digunakan sebagai variabel bebas. Sedangkan observasi dilakukan untuk menghitung nilai RAB yang digunakan sebagai variabel terikat. Analisis data penelitian menggunakan teknik korelasi dan regresi. Dari hasil analisis korelasi dan regresi, variabel yang memiliki hubungan paling tinggi dengan nilai rencana anggaran biaya bata merah dengan nilai koefisien korelasi 0,907 yang berarti variabel bebas tersebut memiliki korelasi yang sangat kuat terhadap variabel terikat. Sementara itu korelasi upah tenaga kerja dan RAB cukup rendah. Dari hasil analisis regresi untuk semua variabel bebas didapat persamaan yang dapat digunakan untuk menghitung nilai RAB yaitu, RAB = 66,823 X1 - 1.277.771 atau RAB = 53,244 X1+ 26,423 X2 -1.826.152, dengan X1 adalah harga batu bata ukuran 22 x 11 x 5,5 per seratus buah yang dinyatakan dalam rupiah dan X2 adalah harga material penutup lantai per meter persegi yang dinyatakan dalam rupiah. Formulasi tersebut memberikan tingkat akurasi yang cukup baik, yaitu diatas 97 %.

The requirement of project management in construction is needed to be able to set priority aspects of implementation from the beginning to the end, to make it succeed and happen as a plan. Self-management is one of the managements to the owner and some scope is to universities that have resources qualified as self-management. Success factor analysis of self-management aims to determine the priority success factors and characteristics of buildings that can be used for self-management. The analytical method used in this research is Analytical Hierarchy Project or AHP. Based on the results of the study, it was obtained 4 respondents who met the criteria for self-management and 10 factors of success, namely quality with 21.33%, leadership / managerial 16.94%, cost 16.89%, 15.68% customer satisfaction, administration 8%, human resources 7.40%, and the other factors such as time with 4.79%, suppliers 3.24%, labor 3.17%, and place characteristics 1.99%. The characteristics of buildings can be done independently, namely; having location or place of development that is owned by the community in a certain area, possessing the development that empowers human resources belonging to mass organizations and community groups, and owning a team of consultants and supervisors to improve planning, scheduling, and increased supervision.
Procurement of residential buildings or houses in a region requires a standard calculation method. In reality, such planning for housing in Indonesia has not been calculated based on a standard. With such standard, the development stage can be carried out with measurable resource requirements. The purpose of this research is to develop a method for calculating housing needs for an area so that this method can be used as a basis for procurement of housing in regions in Indonesia. The methodology used in this research is drafting the concept, trial and error based on the concept, discussing with experts and validating the results. The result of this research indicated that this calculation method could be used at various levels of the regions in Indonesia.Keywords: planning, procurement, housing, region
In construction procurement in Indonesia there are still deviations in the tender process. The deviation is caused by an opportunity during the construction bidding process. The service providers are mutually looking for opportunities to seek personal or group benefits or from the working group that makes these deviations. This causes state losses due to deviations in the construction bidding process. This research was conducted by collecting data from institutions that have the authority to decide whether or not deviations occur in the auction process. The institution authorized to decide whether or not a deviation occurs is the Commission for the Supervision of Business Competition of the Republic of Indonesia (KPPU RI). This study uses a questionnaire to find out how much the causes and impacts on state losses are caused by deviations in the auction process and uses the Probability and Impact Matrix method to determine the level of implication values of the causes and impacts of deviations in each case using a case base analysis approach. The results obtained based on the decision are as many as 12 types of deviation based on the case decision. The impact of deviations that occur in construction procurement is material and immaterial losses. The causes of deviation in construction procurement are caused by four factors, namely the factor of wanting to obtain personal or group benefits, opportunities, pressure and business climate. The most contributing factor to the occurrence of deviation is the combined conspiracy and vertical conspiracy resulting in a value of 11.38%.
Irrigation construction project work is a type of project that has a relatively high risk potential compared to other project work. The development of construction projects in Indonesia can be seen from the use of new methods and technologies as well as the increasing number of parties involved. Rehabilitation of the Progomanggis irrigation network is more complicated than other rehabilitation works because it covers a large area and is located in a place with difficult access. Therefore, this work is vulnerable to the risks that will arise. Based on the results of the analysis carried out, it can be concluded that the schedule for opening and closing river water in the Progomanggis Irrigation Network Rehabilitation Project has a very high risk of project performance. The impact of risk on the project is the delay in work time. Other risks are: weather conditions; changes in work methods; shunt materials; and cropping patterns of water-using communities. Risk control on the project is carried out by conducting regular coordination meetings with stakeholders and making adjustments to work methods.Â Â Â
