Abstract

Selection materials suppliers selectively are important things to be done by the contractor because it can save the cost of the project given the fact that more than half of project expenditure is for the material so we need the right management in the procurement of materials. In this study explains the factors to be considered contractor in choosing the material supplier. There are four main factors to be considered in the selection of contractors, namely material supplier quality, delivery, service, and cost which is then translated into 19 sub-variables. By using multiple linear regression obtained 3 factors that influence the decision of the contractor to buy material that is the amount of material being sent, delayed payment, and the accuracy of the information given price.

Abstract

ABSTRACT Banyuwangi Regency is one of the areas prone to natural disasters. According to data from the Regional Disaster Management Agency (BPBD) of Banyuwangi Regency, the disasters that occurred in 2022 resulted in significant damage to infrastructure and forced residents to evacuate. In response to these events, BPBD took several measures, including setting up communal kitchens and planning temporary shelters. Providing safe, durable, and easily transportable shelters is an initial step in disaster mitigation, considering the unpredictable timing and impact of disasters. Modular container units are easily transportable and modifiable, making them suitable for use as shelter buildings. However, in Banyuwangi Regency, there has been no prior use of used containers for evacuation purposes, necessitating a cost estimation. Therefore, this research aims to determine the estimated cost required for the construction of modular container shelters in Banyuwangi Regency. The use of used containers serves as an alternative solution for constructing shelters that are more effective, efficient, and sustainable, despite requiring some improvements. The methodology employed in this research involves interviews with container contractors and AHSP to estimate costs. The results of this study provide an estimated cost for the construction of container shelters. The total estimated cost for constructing modular container shelters within one evacuation area amounts to Rp2,696,817,000.00. The cost breakdown for each task is as follows: construction of container shelter work costs Rp2,377,973,350.58, container shelter transportation costs Rp288,288,000.00, preparation work costs Rp9,612,548.22, and dismantling and installation work costs Rp20,943,200.00.

Abstract

Di Indonesia, selain sampah rumah tangga, sampah terbesar juga dihasilkan dari fasilitas publik, seperti stadion. Dasar mengangkat studi kasus Jakarta International Stadium (JIS) adalah bangunan berkapasitas terbesar di Indonesia mencapai 82.000 penonton sepak bola, memiliki Tempat Pembuangan Sampah (TPS) sementara secara terpadu dengan prinsip 3R, dan telah memperoleh sertifikasi green building dengan peringkat platinum pada tahap design recognition. Dengan prinsip penilaian green building, ada empat kriteria dan tolok ukur memiliki keterkaitan dengan sistem pengelolaan sampah di JIS adalah site/tapak, material dan teknologi, interior bangunan, dan manajemen lingkungan yang dianalisis secara deskriptif dengan menggunakan metode kualitatif. Permasalahan sampah memerlukan penanganan khusus sehingga tujuan dari penelitian ini untuk memberikan wawasan tentang sistem pengelolaan sampah pada bangunan yang memiliki kapasitas besar khususnya di stadion yang masih belum banyak dilakukan. Sistem pengelolaan sampah di JIS, meliputi pewadahan, pengumpulan, dan pengangkutan secara terpadu dan memenuhi regulasi. Ada empat tipe pewadahan, pengumpulan di pick up point dengan jalur akses bukan area publik atau VIP, dan pengangkutannya dengan trash bag menggunakan lift atau tangga yang pada akhirnya sampah dari semua lantai berkumpul di parking level kemudian diangkut dengan motor sampah menuju TPS 3R yang ada di JIS. Total empat poin yang diperoleh dengan prinsip penilaian green building, yaitu pemilihan tapak; kendali asap rokok di lingkungan; dasar pengelolaan sampah; dan pengelolaan sampah tingkat lanjut. Partisipasi penonton sepak bola dalam keterkaitannya dengan sampah harus dipadukan dengan pola pikir dan perilaku bagaimana memperlakukan sampah dengan prinsip 3R.

Abstract

ABSTRACT Technological developments in the construction industry have led to digitalization. One of them is the construction industry starting to implement Building Information Modeling (BIM). BIM is a system for managing information into building models in digital form. BIM processes input into information in the form of building modeling as an aid in the decision-making process at each stage of a construction project. In its application, BIM is still not optimal and has many obstacles. Of the 68 contractors in the city of Denpasar, only 3 contractors have used BIM in implementing their construction projects. Therefore, it is necessary to carry out a study to find out the factors that hinder the implementation of BIM among contractors in the city of Denpasar. The data collection method was carried out using a closed questionnaire which was distributed to 68 contractors in the city of Denpasar. The collected data was analyzed using Principal Component Analysis (PCA) factor analysis. The analysis carried out produced 3 factors that hindered the implementation of BIM in the city of Denpasar. These 3 factors include: difficulty in starting to implement BIM, high costs in implementing BIM, BIM is not a target for contractors. The third factor, namely that BIM is not the contractor's target, is the most dominant factor with the highest mean data value of 3.907.

Abstract

ABSTRACT In hydrological analysis, rainfall intensity data has a very important role and accurate rainfall intensity data input is needed both temporally and spatially. The constraints experienced in Melawi Sub-watershed is the lack of availability of rainfall observation stations which resulted in the lack of rainfall data and loss of data at certain stations and periods. The results of this study are an analysis of 8 (eight) rainfall observation stations in Melawi Sub-watershed, namely STG-01 Sintang, STG-16 Kota Baru, STG-03 Nanga Pinoh, Stasiun BMKG Nanga Pinoh, Stasiun BMKG Susilo, STG-12 Batu Buil, STG-02 Nanga Sepauk, STG-08 Serawai. An alternative that can be used is to fill in missing rainfall data using 5 (five) methods, namely: normal ratio method, reciprocal method, random number method, and Markov chain stochastic analysis method and another alternative is to test the filling method using the rainfall data correction equation from the validated Tropical Rainfall Measuring Mission (TRMM) satellite, namely: Y = 0.373X + 20.182 where Y is synthetic data and X is historical data. Furthermore, from each method, error testing is carried out to get the percentage error of the synthetic data results obtained. The results show that of the five methods above, the average error of the correction equation method Y = 0.373X + 20.182 is 31,96%, which is the smallest percentage value compared to the Markov chain stochastic analysis method 57,86%; Normal Ratio method 62,87%; Random Number method 74,40%; Reciprocal method 83,77%.

Abstract

Flooding is a global natural disaster that occurs frequently, including in the Landak Regency. From several studies that have been conducted in the Landak Regency area, it is known that there has been an increase in the frequency of flooding in the period 1998-2021, and flooding that occurs not only in urban areas but also in rural areas which are upstream of the Landak Sub-watershed. For this reason, information on flood-prone areas in Landak Regency is needed through geospatial maps to minimize flooding in the area. This research aims to map flood-prone areas and determine the classification of flood-prone levels in the Landak Regency. In this research, the data used are (a) data from observation and documentation in the field during floods, (b) data from Focus Group Discussion (FGD) conducted at the hall of the Landak Regency Public Works Office, which discussed flood control strategies in the Landak Subwatershed, (c) data on land slope, land elevation, soil type, land cover, rainfall, river buffer, inundation duration, and inundation height. Then, an overlay of the eight parameters was done, a zoning map of flood-prone areas was made, and the level of the flood-prone regions in Landak Regency was determined. Based on the analysis, the Landak Regency's areas of shallow, low, and moderate vulnerability to flooding are, respectively, 62,819.28 ha (7.58%), 184,504.24 ha (22.28%), 187,524.53 ha (22.64%), high, and very high (19.98%) levels of vulnerability to flooding. Landak Regency's Ngabang Sub-district (53,787.37 ha), Sebangki Sub-district (50,405.59 ha), and Mandor Sub-district (33,800.63 ha), which comprise Sebangki Village, Sungai Segah, Rantau Panjang, Kumpang Tengah, Sumsum, Sekilap, Keramas, Manggang, Amboyo Selatan, and Temiang Sawi, are among the areas with extremely high flood vulnerability.
