Abstract

Construction projects have a very high risk of work accidents. Work accidents will disrupt all project activities that can cause death and loss to the project. A work accident is an undesirable and unexpected incident which could result in loss of life and property. Based on Law No.1 of 1970 concerning work safety, work accident is an unexpected and undesirable event that disrupts the regulated process of an activity and can cause harm to both human victims and property. For this reason, it is necessary to have a construction safety management system using methods Hazard Identification Risk Determining Control (HIRADC). HIRADC will be implemented if there is support from management for occupational safety and health (OSH) in the form of policies, organizational structure and budget. From the studies conducted, the most common hazards are falling, punctured, scratched, tripped, bumped, inhaled dust, electric shock, exposed to concrete splashes with extreme risk of risk of injury, disability and even death. For this reason, there is a need for handling control in the form of mandating the use of PPE, administrative control such as making work instructions, SOP, must have SIO and SILO, installing signs, and doing engineering such as work methods, shopdrawing, providing regular training.

Abstract

Biaya bekisting/perancah termasuk komponen biaya terbesar pada pekerjaan struktur bertingkat. Dari total biaya konstruksi, perkiraan biaya bekisting adalah 10% dan berkisar 40 s/d 60 persen dari biaya beton bertulang. Oleh sebab itu biaya bekisting membutuhkan perhatian khusus, jika kurag tepat dapat menimbulkan pembengkakan biaya dan keterlambatan penyelesaian proyek. Mengingat pekerjaan selanjutnya yaitu pembesian dan pengecoran beton tergantung pada pekerjaan bekising ini. Penelitian ini dilakukan pada Proyek Apartment Arandra Residence Jakarta untuk pekerjaan bekisting balok dan pelat lantai. Disini akan dibandingkan 2 jenis bekisting yaitu bekisting aluma dan scaffolding. Tinjauan dilakukan untuk 15 lantai, dimana balok dan pelat lantainya menggunakan beton fc’ 35. Dari hasil penelitian, diperoleh waktu pelaksanaan pekerjaan bekisting scaffolding 270 hari sedangkan bekisting aluma system 210 hari. Biaya penggunaan bekisting scaffolding sebesar Rp. 5.079.575.760,00 sedangkan bekisting aluma system sebesar Rp. 6.857.471.478,00Penggunaan bekisting aluma system lebih cepat 60 hari dan lebih murah 16,96% dibandingkan bekisting scaffolding.

Abstract

The use of the building is to support activities or as infrastructure for building owners or building users in optimally carrying out their daily activities. The building is expected to be flexible following the flow of changes that occur in the activities of building owners or users later. This is what underlies the need for building maintenance activities. In the LPMP Dormitory building, maintenance activities have not been managed properly. In order for maintenance activities to be better, a maintenance management plan is made on the architectural and utility components for the building. Starting from listing the components that are maintained, then making maintenance classifications of these components, namely preventive maintenance and corrective maintenance. Next, make standard operating procedures for each of these components, complete with a flow chart and checklist form. Scheduling is also an important point in maintenance activities, starting from scheduling daily, weekly, monthly, and yearly components. The total preventive maintenance cost for architectural and utility components in the building is Rp. 303,648,000. This fee is the maintenance fee for one year.

Abstract

Dinding bangunan umumnya terbuat dari bata yang mempunyai beberapa kelemahan diantaranya berat dan getas. Akibat beratnya yang cukup besar maka akan menaikkan beban mati struktur sehingga beban gempa juga akan naik. Hal ini disebabkan karena beban gempa akan meningkat secara linier terhadap berat struktur bangunan tersebut. Sedangkan akibat dari sifatnya yang getas maka pada tingkat perubahan bentuk (deformation) yang relatif rendah retak-retak tidak dapat dihindari (Satiawan, 2016). Salah satu metode perkuatan dinding terhadap keruntuhan adalah dengan metode kawat strimin. Nusantoro, A. 2012, Pemasangan kawat dstrimin dilakukan di sepanjang tulangan, di sebelah luar dan dalam dengan lebar minimal 45 cm. Kemudian kawat strimin diikat (luar dan dalam) dengan menggunakan 2 utas kawat D2 mm, terakahir ditutup dengan mortar. Dengan teknologi ini, masyarakat dapat memperkuat dinding rumah tinggal mereka terhadap gempa dengan biaya yang murah, material mudah didapat dan waktu pelaksanaan yang singkat serta pengerjaan yang tidak rumit. Tujuan yang ingin dicapai dari kegiatan pengabdian ini adalah dapat memberikan wawasan, meningkatkan ketrampilan/skill bagi masyarakat Kampani dalam memperbaiki rumah tinggal agar mempunyai perkuatan terhadap gempa dengan metode kawat strimin. Metode yang diterapkan pada kegiatan ini dengan melakukan penyuluhan, sosialisasi, diskusi dengan pemuka masyarakat dan memberikan palatihan pemasangan kawat strimin untuk mencegah keruntuhan getas.

Abstract

In general, the seismic design provisions around the world present different criteria for local soil conditions depending on soil and rock properties to determine the design spectra representing seismic design. On the other hand, site-specific analysis results not only show the main characteristics of soil-rock profiles but also local soil characteristics where detailed studies are needed to review the earth response to earthquakes. In this study conducted Site Specific Response Analysis (SSRA) is to analyze the earthquake wave propagation from the bedrock to the surface layer. The data needed are ground stratification data and shear wave velocity parameters obtained from empirical correlation to N-SPT test drilling data. In addition, the required data is ground motion synthetic at baserocks used for the earthquake wave propagation obtained by Probabilistic Seismic Hazard Analysis (PSHA) 3-dimensional earthquake source referring from the results of previous research. SSRA is based on the theory of single-dimensional wave propagation in time domain using NERA (Non-linear Earthquake Response Analysis) program. Various inputs of earthquake movement are taken by considering suitable for Padang area. The results of this analysis are shown in the form of historical time acceleration graph and peak acceleration from each bore point location which is then processed to obtain amplification and response spectra design factors for the re-quake period of 475 years and 2475 years.

Abstract

This research is motivated by the frequent occurrence of work accidents in construction projects during 2017-2018, this gives a meaning that there is still a lack of attention to aspects of occupational health and safety (OHS). Therefore a plan is made which, if implemented in a project, can minimize the occurrence of work accidents called the construction safety plan. The purpose of this research is to make a construction safety plan by identifying any risks that can cause work accidents in construction projects. This research is based on direct observation methods on construction projects and literature studies related to risk and OHS. This research begins by identifying risks based on the Minister of Public Works Regulation PERMENPU NUMBER: 05 / PRT / M / 2014 where there will be hazards that can cause workplace accidents and how to control them, then a construction safety plan consisting of work safety policies, targets and work safety programs, and implementation of workplace safety activities in the field. The results of this study are that there are 36 risk variables that can cause work accidents, consisting of 7 variables with high risk, 21 variables with moderate risk and 8 variables with low risk. The targets made were the achievement of zero accidents with safety induction programs, safety precautions, safety talk, safety meetings, safety patrols and the use of personal protective equipment. Then the implementation plan of work safety in the field includes evacuation route planning, building protection planning, planning to work at height, etc.
