Abstract

Beberapa tahun terakhir Indonesia sering terjadi gempa, oleh sebab itu penerapan salah satu sistem rangka untu k bangunan tahan gempa yaitu special moment frame (SMF) bisa menjadi modal alternatif demi menekan angka kerusakan pada bangunan yang terjadi. Perhitungan pada konstruksi baja dengan sistem special moment frame mengacu pada SNI 1729:2015 tentang Tata Cara Perencanaan Ketahanan Gempa untuk Struktur Bangunan Gedung, SNI 1726:2019 tentang Tata cara perencanaan ketahanan gempa untuk struktur gedung dan non gedung, dan untuk seismik menggunakan AISC 341-10. Selain penggunan sistem special moment frame (SMF) pada struktur juga bisa menggunakan base isolation system yaitu lead rubber bearing (LRB) sebagai tambahan pada stuktur bawah. Penggunaan lead rubber bearing di daerah rawan gempa sangat membantu dalam menekan kerusakan pada sebuah bangunan. Perbandingan penggunaan fixed base dibandingkan isolation base cukup terlihat dalam segi keamanan. Pada perioda struktur getar meningkat sebesar 45% dibandingkan dengan fixed base dan dapat disimpulkan bahwa dengan isolation base bisa memberikan kekakuan yang lebih baik. Jika ditinjau dari simpangan antar lantai terjadi penurunan pada kedua arah. pada arah x mengalami penuran berkisar 65% sedangkan pada arah sebaliknya yaitu y mengalami penurunan sebesar 52%.

Abstract

ABSTRACT The Government of Indonesia was committed to encouraging public-private partnership (PPP) schemes to address gaps in infrastructure development. But not all projects offered through the PPP scheme have a high degree of eligibility because the project is a long-term investment with a considerable degree of risk challenge. Efforts to improve the feasibility of investing in toll road PPP projects were made such as investment guarantees and incentives for the private sector. This study is a continuation of previous research that was an implementation of the incentive system in PPP project contract to increase investment feasibility. In this study, the authors want to obtain a general description of:(1) Existing condition of research location and land use based on Local Regulation around Bali Mandara Highway (Field Observation and Local Regulation), (2) To know the wishes of the people around Highway in a location that allows applied spatial use incentive system (Interview Method), (3) Assessing the spatial plan at the foot of the toll road regarding spatial use plan with guidance on incentives and density utilization of space on the highway (method of cropping the map). From the result of the research, it can be seen the general description of the people's desire to play a role in the utilization of space around the Nusa Dua toll, where the results of satellite image analysis and the spatial regulation on spatial planning allow the availability of land for spatial use activities around highway about 10 hectares. Keywords: highway, KPS, spatial, use of space

Abstract

Gaps Infrastructure financing in Indonesia must be sought out, one of which is to improve the performance of PPP projects to be bankable / economically viable / investment-worthy so that investors / private companies are willing / interested in investing in infrastructure projects. with Malaysia which now has more than 3000 km of toll roads. The incentive system is implemented in developed countries to improve the performance of feasibility and anticipate risks in toll road KPS projects that have long-term contract / concession time. Burris, Baker, Geiselbrecht (2014). The government needs to make a breakthrough to provide space utilization incentives as a form of controlling the use of space where investors and the public can participate by working together to increase toll revenues. The intended use of space is the management of the area around the toll road with a certain amount of area and the allocation of the management plan that has the maximum economic impact so that investors can obtain other income that can be included in the toll revenue cash flow. This study uses the AHP method with digital analysis with Expert Choice to produce the following analysis: the highest criteria for incentive for space utilization activities. The highest sub-criteria are in the physical provision of compensation from the government to the community where the land is applied to incentives for spatial use.

Abstract

Indonesia has a high earthquake risk, therefore several buildings in Indonesia are designed with seismic retention systems where the column structure is designed to be stronger than the beam. The calculation of apartment building structure in this final design is based on SNI 1726:2012 and SNI 2847:2013. The method used in this calculation is the Special Moment Resisting Frame System (SMRFS) because the building area is included in the category of E seismic design which is a type of soft soil. The Special Moment Resisting Frame System is designed so that the building has more strength to withstand earthquakes, especially the column structure. This building is classified as a high-level building, therefore the analysis of seismic load is carried out by Spectrum Response Dynamic, using the SRSS (Square Root of the Sum Squares) method because the building structure has far-flung natural vibration times. In high-rise buildings, it is necessary to control the displacement between floors to reduce the large sway on each floor. The displacement between floors resulting from elastic analysis is less than the maximum allowable intersection between floors. so that the building structure is still safe against swaying.

Abstract

The success and failure of project implementation is often caused by poor planning and ineffective controls, so that project activities experience various obstacles such as the late completion of the project, the decline in the quality of work and the swelling of implementation costs. Project management is carried out to manage the project from the beginning of the project until the completion of the project properly. The case study in this study is PT. PP (Persero) Tbk. as the executing element of the construction work, it is in charge of organizing the construction of the Surabaya Caspian Tower Apartment in East Java. The CPM (Critical Path Method) method is used to find out how long a project has been completed and look for possible acceleration of project time. From the research using the CPM method, it can be seen that the normal duration of project completion is 453 days which can be optimized to 350 days. This can be done by giving special attention to activities included in the critical path and accelerating some activities by increasing the number of workers
