<![CDATA[This research will discuss about contractors with concrete suppliers and formwork suppliers. The research is conducted to look for ranking criteria and sub-criteria used by contractors to selecting and evaluating concrete and formwork suppliers. The criteria and sub-criteria are refer to Ho et al., (2007) and three new sub-criteria are added, which are a guarantee, lowest price guarantee, and payment term. The contractor classification is divided into four namely general classification, NPK classification consisting of non-classification; individual; small business, medium business classification, and big business classification. Ranking for criteria and sub-criteria are sought based on the mean value for each classification material both in the context of selection and evaluation. After finding the ranking, it is sought whether there is a difference of importance between the NPK classification, middle, and large of the priority sub-criteria in general classification using the Kruskal Wallis test.]]>

<![CDATA[Today, concrete quality prediction can be performed with the help of artificial intelligence (AI) to solve existing problems. However, determining the best AI method for predicting concrete compressive strength remains an open question. Therefore, this research evaluates the most accurate AI modeling for predicting various kinds of concrete mixtures. AI methods used in this study are artificial neural networks (ANN), support vector machines (SVM), classification and regression trees (CART), and linear regression (LR). Furthermore, these four AI methods are run with several parameters and tested with 4 different kinds of concrete dataset. Four error indicators and 1 normalization indicator are used to evaluate AI and determine the best AI method. From the Obtained results, indicate that ANN has the best performance when compared with 3 other AI methods. It can be seen that from ANN produced smaller error values when compared to the other three AI methods.]]>

<![CDATA[The slowing of economic growth in Indonesia could cause financial distress for companies in property, construction and real estate sectors as these companies has enormous amount of GDP contributions in Indonesia. These difficulties are related to companies being able to accomplish all its responsibilities in short nor long terms. In assessing financial status of a company, discriminant analysis could be of use to see financial ratio such as liquidity ratio, profitability, activity and solvability. This research consists of comparative and sample pulling technique towards 81 population in multiple sectors such as property, construction and real estate. Data collection method by documentation. Discriminant analysis results depicts that liquidity ratio(CA/CL), profitability (EBIT/TA and NI/SALES), activity (SALES/TA), and solvability (BV/TL and TL/EQUITY) could be used to distinguish which company are experiencing financial distress and which are not.]]>

<![CDATA[The importance level of risk throughout the construction progress is apparently inherit tendermous impact on the ultimate project performance and client satisfaction. Such determination level of risk in terms of frequency, time risk as well as cost effect to be perceived from two perspectives, owner and contractor, is inventably crucial to be researched, primarily for housing construction in Surabaya. This study was conducted by applying a survey through some questionnaires to observe 30 risks that have been identified from the previous literature. Total respondents involved were 69 respondents consisting of 29 respondents representing the owner / developer and 40 respondents representing the contractor. The results of this research, as from owners’ perspective, shows bad weather was the most common risk, followed by contractors’ financial difficulties which has the utmost impact on time and increasing material price takes major part on costs respectively. Whereas according to the contractor, design changes from consultants / owners are the most frequent risks, design changes from consultants / owners have prominent impact on time and lastly worker productivity also siginificantly reinforces expense factor.]]>

<![CDATA[Global warming has been increasing since last 5th years. This problem emerged because of the development of highrise building these days. In a building, air conditioning system has the largest percentage of building’s energy consumption, 55-65% of total building’s energy consumption. An efficient and economic air-conditioning system is needed to save energy and operational cost as much as possible. Life cycle cost analysis is conducted to evaluate the air conditioning system by comparing some alternatives system. The datas are retrieved from building management and some supplier, also mechanical and electrical contractors. This research is conducted by calculating the investment cost (C), operational cost (O), maintenance and replacement cost (R), and salvage value (S). Before calculating life cycle cost, all cost is converted with annual worth method. Life cycle cost evaluation is capable to save operational cost up to 34%.]]>

<![CDATA[This paper discusses the prefabricated construction method by taking a case study of Dian Sukolilo Regency housing construction, Surabaya. Prefabricated construction methods are able to provide faster construction times and better quality. Stages of research will be carried out by processing real data with a simulation calculation approach to obtain the calculation of the budget plan and estimated time of construction using the prefabrication method. The main variables that influence this prefabricated construction method are four namely cost, time, quality and number of units. The increasing number of units will reduce the cost of construction of the construction unit using the prefabrication method. The results of each research calculation will guide the interview to find out the response of the housing developer to the prefabricated construction method whose results will be the conclusion of the study.]]>

<![CDATA[Banyak penelitian yang telah dilakukan untuk mempelajari faktor keterlambatan di proyek konstruksi jalan di Kota Ambon. PT X sering mengalami keterlambatan dalam menyelesaikan pekerjaan. Penelitian bertujuan meminimalkan rIsiko dan dampak keterlambatan yang dialami PT X. Penelitian ini menggunakan metode FMEA karena dapat memprioritaskan risiko proyek menggunakan item pekerjaannya. Prioritas item pekerjaan di pilih yang memiliki RPN di atas 125 Pengambilan data dilakukan dua kali wawancara dan teknik 5 Whys digunakan mencari akar permasalahan. Hasil selama wawancara adalah mendapatkan faktor risiko yang menyebabkan keterlambatan, nilai RPN dengan pedoman tabel SOD, menganalisis risiko, memberikan solusi dan memastikan nilai RPN lebih kecil dari 125. Dari hasil penelitian ditemukan kemiripan faktor risiko yang menyebabkan keterlambatan antara proyek 1 dan proyek 2, dengan proses pengerjaan di tahun yang bebeda. Faktor-faktor risiko tersebut terjadi karena penerapan sistem di perusahaan yang kurang diperhatikan. Implentasi metode FMEA untuk proyek konstruksi dapat digunakan meskipun item pekerjaannya banyak.]]>

<![CDATA[Makalah ini membahas tentang metode konstruksi prefabrikasi dengan mengambil studi kasus pembangunan perumahan Dian Sukolilo Regency, Surabaya. Metode konstruksi prefabrikasi mampu memberikan waktu konstruksi yang lebih cepat dan kualitas yang lebih baik. Tahapan penelitian akan dilakukan dengan mengolah data dengan pendekatan perhitungan simulasi untuk memperoleh perhitungan rencana anggaran biaya dan estimasi waktu konstruksi dengan metode prefabrikasi. Variabel utama yang mempengaruhi metode konstruksi prefabrikasi ini ada empat yaitu biaya, waktu, kualitas dan jumlah unit. Jumlah unit yang semakin banyak akan memberikan penurunan biaya konstruksi satuan unit pembangunan dengan metode prefabrikasi. Hasil dari perhitungan penelitian masing- masing akan menjadi pedoman wawancara untuk mengetahui respon dari pihak pengembang perumahan terhadap metode konstruksi prefabrikasi yang hasilnya akan menjadi kesimpulan penelitian.]]>
