This earthquake disaster has caused many casualties. Some casualties were injured by the light damaged to collapsed buildings and infrastructures. Based on Presidential Instruction (INPRES) No.5 of 2018, Ministry of Public Works and Housing (PWH) was assigned to carry out rehabilitations and reconstructions after the earthquake. The areas that had been affected by the earthquakes are Mataram city, North Lombok Regency, West Lombok Regency, Central Lombok Regency, East Lombok Regency, West Sumbawa Regency, and Sumbawa Regency. The Mandate of INPRES No. 5 of 2018, is that the reconstruction process must be carried out using earthquake resistant building technology and in a short time. To answer these tasks and challenges, the Ministry of PWH used the construction of Simple Healthy Instant Houses (Rumah Instan Sederhana Sehat or RISHA ), as earthquake resistant building technology that had been developed and owned by the Ministry of PWH. RISHA construction is not only an earthquake resistant building technology, but also a construction using knock down technology with precast system so that it can be constructed in a relative fast time. This paper discusses the activities of reconstructing educational facilities in Sumbawa Regency, NTB Province using RISHA construction.</p> Faiz Sulthan Copyright (c) 2020-01-19 2020-01-19 8 2 37 43 10.35139/cantilever.v8i2.11 Prediksi dan Analisis Data Gempa Bumi di Provinsi Bengkulu dengan Metode Artificial Neural Network http://cantilever.id/index.php/cantilever/article/view/5 <p>Many things that have experienced technological advancements are one of which is the continued development of software. One example of software development today is the Matlab software. Matlab is currently able to be used to predict and analyze an existing problem. A lot of research has been done with the use of matlab software. Artificial Neural Network (ANN) is one of the command languages ​​used in the matlab program which is used to predict the data entered. Besides that, Bengkulu Province is one of the earthquake and tsunami prone areas in Indonesia. This is because Bengkulu is in the subduction zone (collision) of active plate encounters in Indonesia Australia and Eurasia. Recording earthquake data must be recorded properly because this earthquake data will often be used, both for development and for the environment. The ANN method uses trial epoch until the smallest error is obtained. The smallest error results stopped at the Epoch 2000 trial. The Epoch 2000 trial produced the biggest error of 59.1% and the smallest error of 2.93%. The results of this study, obtained ANN is quite capable of calculating earthquake data predictions in the province of Bengkulu in 2018.</p> Fadhila Firdausa Copyright (c) 2020-01-19 2020-01-19 8 2 45 49 10.35139/cantilever.v8i2.5 Analisis Faktor Dominan yang Mengakibatkan Pembengkakan Biaya oleh Kontraktor pada Proyek Jalan Kabupaten Wonogiri APBD Tahun 2017 dan 2018 http://cantilever.id/index.php/cantilever/article/view/8 <p>The implementation of the road project in Wonogiri Regency was often different between the planning with has be held that making problem for contractor like as late work and cost overrun. Therefore, the purpose of this research is knowing what is cost overrun factors and also amount of cost overruns of the road project in Wonogiri Regency which used APBD 2017 and 2018 experienced by contractor. This research was conducted by asking questions to the contractor who worked on the road project in 2017 and 2018. The analysis of this research has using the SPSS program. Based on the analysis has been done, field regulation become dominant of cost overrun. The lack of provision of field support facilities and the limited size of the project area are the reasons why field regulation factors can be a major factor causing cost overruns on road projects in Wonogiri Regency. Based on the answers from respondents it can be concluded that the contractors who experienced a swelling cost of 1% -5% there were 44 respondents, then for the cost swelling of 6% -10% there were 28 respondents, and 11% -15% there were 2 respondents, and 16% -20% only 1 respondent.</p> Muhammad Nur Sahid Anto Budi Listyawan Abdul Rochman Rim Dzaky Haidar Rim Copyright (c) 2020-01-28 2020-01-28 8 2 51 57 10.35139/cantilever.v8i2.8 Perencanaan Sistem Instalasi Pengolahan Air Limbah Komunal di Perumahan Grand Ville Taba Lestari Kota Lubuklinggau Provinsi Sumatera Selatan http://cantilever.id/index.php/cantilever/article/view/14 <p>The purpose of this research are to plan, design and estimate the construction cost of a communal wastewater treatment system in the Grand Ville Taba Lestari housing town of Lubuklinggau. The domestic wastewater, comes from businesses, residential activities, restaurants, offices, apartments and dormitories. The wastewater distribution system for residential area uses a shallow sewer system, namely domestic wastewater from sanitary ware (latrines, sinks, floor drain, kitchen sink, etc.) directly connected using a wastewater pipe and the wastewater distribution system in this design, uses a gravity system. Communal wastewater treatment plant is expected to prevent and reduce the occurrence of environmental pollution. From the site-plan, the maximum number of occupant are 369 persons, resulting in a wastewater debit of 40.51 m<sup>3</sup>/day. The designed dimensions of the wastewater treatment plant are based on the amount of wastewater produced, which is 9.5 m long, 3 m wide with a depth of 2 m. Piping network are 475.50 m of parcel pipe, 478.93 m of service pipe, 434.6 m of lateral pipe and 3 m of main pipe. The cost required for constructing the communal wastewater treatment plant in the Grand Ville Taba Lestari Housing is Rp. 335,500,000.00.-.</p> Okma Yendri Herpi Deska Ardinata Copyright (c) 2020-02-01 2020-02-01 8 2 59 64 10.35139/cantilever.v8i2.14 Studi Penggunaan Plastik Polypropylene pada Campuran Asphalt Concrete-Wearing Course http://cantilever.id/index.php/cantilever/article/view/13 <p>The quality of implementation, drainage, materials that do not meet the standards, and overloaded from the specified class of roads are the main causes of road damage. Thus violations and negligence both in the implementation or maintenance of the road can cause a lot of traffic accidents, damage to vehicles, and various things that can disrupt the comfort and safety of drivers or pedestrians. The purpose of this study was to evaluate the effect of polypropylene plastic as an additive in the Asphalt Concrete-Wearing Course (AC-WC) layer. The use of polypropylene waste used as an additive is around 2.5%; 3.5%; 4.5%; and 5.5% of the asphalt weight. Based on the results of the analysis it was concluded that the mixture of AC-WC with the addition of polypropylene plastic experienced increased stability and decreased melting. Polypropylene plastic which can be used based on the five Marshall test parameters with the highest value of stability and lowest melting is 4.5% of the weight of asphalt.</p> Lie Ing Tan Wildan Reza Pahlevi Copyright (c) 2020 Lie Ing Tan, Wildan Reza Pahlevi https://creativecommons.org/licenses/by-nc/4.0 2020-02-11 2020-02-11 8 2 65 71 10.35139/cantilever.v8i2.13 Kinerja Struktur Sistem Tunggal dan Ganda dengan Performance Based Design http://cantilever.id/index.php/cantilever/article/view/21 <p>The structure of a simple rental apartment building of the Sumatran Technology Institute had been modeled using the <em>Performance Based Design</em> method. The aim of this study was to obtain the base shear and maximum displacement as well as the performance level of the building structure models in resisting the combination of gravitation and lateral earthquake loads. The loads were based on the function and location of the building. The building structures had been designed as a double system, namely the beam-column frames and shear walls in the direction of the XZ and YZ axis. There were four models: the models with a double system according to the original design, the beam-column frames without XZ shear walls, the beam-column frames without YZ shear walls, and the beam-column frames without shear walls. The results of the analysis at the performance level showed that the model with a double system was able to resist the highest base shear while the frames system without shear walls was only able to resist the lowest base shear compared to other models. The inter story drift under earthquake loads in the direction of the X and Y axis showed that all models of structural system were still within the safe limit.</p> Siti Aisyah Nurjannah Hanafiah Wanda Lestari Erwin Lim Iswandi Imran Copyright (c) 2020 Siti Aisyah Nurjannah, Hanafiah, Wanda Lestari, Erwin Lim, Iswandi Imran https://creativecommons.org/licenses/by-nc/4.0 2020-03-22 2020-03-22 8 2 73 81 10.35139/cantilever.v8i2.21
