<![CDATA[Optimasi topologi dari struktur rangka batang baja memberikan hasil yang lebih optimal dibandingkan optimasi ukuran penampang karena batang dan nodes yang tidak berguna pada struktur dapat dihilangkan. Fungsi objektif dari algoritma metaheuristik adalah untuk meminimalkan massa struktur rangka batang baja terhadap constraints statis dan dinamis berdasarkan studi kasus dan spesifikasi bangunan baja struktural Indonesia, SNI 1729:2015. Empat algoritma yang digunakan pada studi ini adalah: Particle Swarm Optimization, Differential Evolution, Teaching-Learning-Based Optimization, dan Symbiotic Organisms Search. Keempat algoritma tersebut diuji pada studi kasus 24-bar truss. Performa dari algoritma diukur dari lima kriteria massa, yaitu: massa terbaik, terburuk, rata-rata, standar deviasi, dan median dari struktur rangka batang baja. Hasil penelitian menunjukkan SOS menunjukkan performa terbaik pada studi kasus 24-bar truss.]]>

<![CDATA[Dalam mendesain suatu gedung apartemen yang ekonomis dan efisien, analisis life cycle cost dibutuhkan untuk mendapatkan desain yang paling efisien selama umur pakai bangunan. Berdasarkan penelitian sebelumnya, telah didapatkan bahwa biaya energi merupakan komponen biaya terbesar dalam life cycle cost suatu gedung. Data pada penelitian ini berasal dari manajemen pengelola gedung dan beberapa supplier produk dan peralatan yang di teliti. Analisis penelitian ini dilakukan dengan menjumlahkan biaya awal (C), biaya perawatan (M), biaya operasional (O), biaya penggantian (R) dari tiap produk dan peralatan. Sebelum dijumlahkan semua biaya dikonversikan dengan metode annual cost. Penelitian ini menunjukan bahwa penggunaan metode LCC pada saat menentukan peralatan mekanikal dan elektrikal yang digunakan pada suatu gedung apartemen dapat menghasilkan penghematan pada biaya pengelolaan gedung. Selain itu penelitian ini menunjukan bahawa sumber pendanaan awal yang berasal dari pinjaman bank tidak memberikan pengaruh terhadap pengambilan keputusan untuk pemilihan suatu produk dan peralatan yang berkaitan dengan energi In designing an apartment building that is economical and efficient, life cycle cost analysis is needed to obtain the most efficient design for service life of the building. Based on previous studies, it has been found that the energy cost is the largest cost component in the life cycle cost of a building. The data in this study came from the building management and from multiple suppliers of products and equipment. The analysis is done by summing the initial cost (C), the cost of maintenance (M), operating costs (O), the cost of replacement (R) of each product and equipment. Before all of the costs being added, these costs converted to annual cost method. This study shows that the use of the LCC method when determining the mechanical and electrical equipment used in an apartment building can result in savings on the building operational cost. In addition, these studies show that the source of initial funding from bank loans does not give effect to the decision making for the selection of a product and equipment related to energy.]]>

<![CDATA[ABSTRAK: Penjadwalan merupakan suatu hal yang sangat penting karena akan menentukan sebuah proyek selesai pada waktu yang ditentukan atau malah melebihi dari yang ditentukan, apabila melebihi dari yang ditentukan maka akan terkena sanksi. Penelitian ini dilakukan studi kasus pada proyek apartemen yang berlokasi di Surabaya bagian barat dimana metode yang dilakukan adalah dengan menggunakan takt time planning pada pekerjaan finishing dan MEP. Data-Data yang dibutuhkan didapatkan dengan cara meminta kepada chief engineering dan setelah data tersebut didapatkan maka diolah menjadi suatu perencanaan baru dengan menggunakan metode takt time planning. Dalam pengolahannya dibutuhkan koordinasi dengan orang-orang dilapangan supaya tidak terjadi kendala pada saat pelaksanaan nya sehingga dapat menghasilkan hasil yang diharapkan. Hasil dari penelitian ini didapatkan bahwa perencanaan dengan menggunakan metode takt time yaitu terjadinya keselarasan dalam tiap-tiap pekerjaan selain itu juga dapat mempercepat durasi proyek sebesar 1 minggu dari perencaan awal.]]>

<![CDATA[Nowadays, the minimization of project time and cost is an important issue. However, time and cost problems are difficult to solve. They are affected by the uncertain factor. Then, the construction project always fails to achieve the effectiveness of time and cost performance. It causes delays and cost overrun. In this research, SOS-NN-LSTM is required to establish the estimate schedule to completion (ESTC) and estimate cost to completion (ECTC) prediction model based on time now performance. Then, the prediction model will be integrated with MOSOS to obtain the optimal prediction value. The integration is needed because there is no direct equation to calculate the ESTC and ECTC. The Pareto curve identified based on the prediction values of MOSOS. The Pareto curve is used to determine the optimal trade-off between project duration and project cost. Then, the indifference curve is used to solve the trade-off problem between estimate schedule at completion (ESAC) dan estimate cost at completion (ECAC) which give the decision-maker preference.]]>

<![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.]]>
