Abstract

The damage caused by earthquakes can be minimized by planning and constructing earthquake-resistant buildings. In efforts to mitigate earthquake risk, residential houses must be built with earthquake reinforcement, by adding seismic reinforcement to structural components (foundations, beams, columns) and non-structural components (walls, roofs). The addition of earthquake reinforcement features to housing only adds 5% to the total implementation cost, which is very small compared to the risks that will be faced. The earthquake reinforcement features are applied based on the Technical Guidelines for Earthquake Resistant Houses and Buildings (Directorate General of Cipta Karya and the Department of Public Works) number 5 of 2006, SNI 1726-2019 regarding Procedures for Earthquake Resistance Planning for Building Structures and Non-Building Structures, as well as SNI 1727:2020 regarding minimum design loads and related criteria for buildings and other structures. With the knowledge and skills acquired, it is hoped that the partners will be able to directly apply them to the houses they will build as an effort to mitigate earthquakes and minimize risks and losses that may occur. The objectives to be achieved from this community service activity are: partners to understand the features of earthquake reinforcement in residential homes; partners to acquire skills and training in the methods of creating earthquake-safe dwellings; partners to apply this in the housing they build. The method to be employed in this activity will include field surveys, counseling/socialization, and technical training for the application of earthquake reinforcement on structural components (foundations, beams, columns) and non-structural components (walls, roofs). This activity was attended by 13 participants, with the success identified based on the level of understanding absorbed during the socialization in the discussion session.

Abstract

Almost all regions of Indonesia are geographically vulnerable to natural disasters, earthquake. One way to implement a very long and structurally stable building design in the event of an earthquake or other circumstances is to provide a dilation system for the building. This research was conducted in a multi-storey parking building project at Airlangga University Campus B which applies a cantilever beam dilatation system and will be compared with a two-column dilatation system in terms of cost and time. Cantilever beam dilatation is a structural separation that uses a beam structure with one end having a clamp and the other end is free, while two-column dilatation is a structural separation that uses two columns side by side with a certain distance. From the results of the study, it was found that the cost of structural work with cantilever beam dilatation was Rp. 76,755,100,000, - and for two-column dilatation is Rp. 76.063.550.000,- while the total project time with cantilever beam dilatation is 451 working days, and for two-column dilatation is 447 working days. The application of two-column dilatation is 0.9% more cheaper and four days earlier than the application of the cantilever beam dilatation system.

Abstract

The success of construction project is determined by the management of cost, quality, and time. Mismatches between the initial plan and field conditions often cause delays and cost overruns. Project X with a cost of IDR 4,144,190,311.75 with a planned implementation time of 180 days, experienced a delay with a deviation of -10.09% on the 91st day. This study aims to analyze project acceleration to delays solution by implementing the evaluation variance at schedule method, earned value and time cost trade off method. The results of the study using the evaluation variance at schedule method, that the delay manajement index was 0.36, and delay production index was 0,64. This delay caused by delay of material arrivals, low labor productivity, and low skilled workers in project. With the earned value, the estimated project completion time was 215 days, its mean 35 days late with an estimated project completion cost of IDR 4,775,028,805.39. The result time cost trade off method with the addition of work shifts, add cost IDR 780,771,895.34 and total cost is IDR 4,924,962,207.09 and 180 days. With the addition of working hours (overtime), add cost IDR 836,528,250.97 and total cost is IDR 4,980,718.562.72 and 188 days. The addition of work shifts is recommended for delay solution.

Abstract

AbstrakKota Padang berada pada wilayah dengan bahaya gempa yang perlu direspons melalui peningkatan kualitas konstruksi rumah tinggal. Dinding pasangan bata pada rumah sederhana rentan mengalami retak, terlepas dari rangka, dan runtuh ketika menerima gaya lateral. Kegiatan pengabdian ini bertujuan membekali karyawan dan pekerja PT Adiwidia Cipta Amerta Padang dengan pemahaman dasar dan pengalaman praktik penerapan ferrocement layers sebagai perkuatan dinding untuk mengurangi risiko keruntuhan mendadak akibat gempa. Program dilaksanakan pada 14 Juni 2025 melalui identifikasi kebutuhan, persiapan, sosialisasi, pelatihan teknis, serta evaluasi dan tindak lanjut. Evaluasi kuantitatif menggunakan indikator proses dan luaran yang dapat diverifikasi dari daftar hadir, dokumentasi, dan catatan pelaksanaan. Kegiatan diikuti oleh sembilan peserta yang mengikuti rangkaian sosialisasi dan pelatihan teknis. Seluruh lima tahap program dan lima komponen inti demonstrasi terlaksana, masing-masing mencapai keterlaksanaan 100%. Kegiatan menghasilkan satu modul teknis dan satu segmen dinding demonstrasi atau dua dari dua luaran utama. Secara kualitatif, diskusi peserta berfokus pada fungsi angkur, posisi wire mesh, mutu mortar, ketebalan lapisan, biaya, dan pengendalian mutu. Program menyediakan dasar praktis bagi mitra untuk memasukkan detail perkuatan dinding ke dalam pengarahan pekerja dan pengawasan lapangan. Peningkatan pengetahuan peserta belum dapat dinyatakan dalam persentase karena kegiatan tidak memiliki rekaman skor tes awal dan tes akhir. Kata kunci: gempa bumi; ferrocement layers; perkuatan dinding, rumah tinggal; dan pelatihan teknis. AbstractPadang is exposed to substantial seismic hazards that require improved construction practices for residential buildings. Masonry walls in simple houses are vulnerable to cracking, separation from the frame, and sudden collapse under lateral loads. This community service program aimed to provide employees and construction workers of PT Adiwidia Cipta Amerta Padang with basic knowledge and hands-on experience in applying ferrocement layers as wall reinforcement to reduce the risk of sudden earthquake-induced collapse. The program was conducted on 14 June 2025 through needs identification, preparation, dissemination, technical training, evaluation, and follow-up planning. Quantitative evaluation used verifiable process and output indicators derived from attendance records, documentation, and implementation notes. Nine participants took part in both the dissemination session and technical training. All five program stages and five core technical demonstration components were completed, representing 100% implementation. The activity produced one technical module and one wall demonstration segment, fulfilling two of two principal outputs. Qualitative observations showed that participant discussions focused on anchor functions, wire-mesh positioning, mortar quality, layer thickness, costs, and quality control. The program provides a practical basis for the partner to incorporate wall-reinforcement details into worker briefings and site supervision. A percentage increase in participant knowledge is not claimed because no recorded pre-test and post-test scores were available. Keywords: earthquake; ferrocement layers; wall reinforcement; residential building; technical training.
