Abstract

In the development of the implementation of building construction projects, work is often delayed from the specified time, to overcome this, an implementation method is needed, one of which is using Network Planning with the Critical Path Method (CPM ). CPM is a basic method of planning and controlling a work system based on a network or network that can increase efficiency and effectiveness in allocating time and costs. The research method used is the primary research method, conducting observations or direct observations in the field and conducting face-to-face interviews on projects being implemented with a self-management system, carried out by the SMK Negeri 1 Bualemo school by forming a school construction team (P2S). The application of network planning with the CPM method in building construction can accelerate the project implementation schedule compared to the specified time and can increase the cost effectiveness of project implementation. The results of the study using CPM are known to be Critical Paths, namely Activities A – C – H – L – M – N – T – W – X – Y with the original project completion time of 175 days to 157 days, optimizing the time by 18 days, with the original Budget of Rp. 2,224,035. 000,- to Rp. 2,140,996,000 ,- cost optimization of Rp. 83,038,723.02.

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

Roads with flexible pavement use asphalt as a binding aggregate so that it is much in demand rather than rigid pavement. Road infrastructure requires ongoing maintenance. The use of plastic packaging cannot be separated in everyday life. HDPE is a high density polyethylene. Based on the problem of the amount of used plastic waste currently available, this research is needed to find out how well the pavement uses the use of HDPE plastic as a mixed plastic waste. After testing in the laboratory and analyzing it according to the General Specifications of the Highway for normal composition without a plastic mixture of 0%, the asphalt content that meets all the requirements is estimated at asphalt level between 5.6% - 6%. From the results of the study with 4 different compositions, it was found that the optimal asphalt content composition of HDPE plastic mix 0%, 4%, 8% and 12% that meet the VIM and Stability obtained optimal 8% HDPE plastic mixture with an optimal asphalt content of 4.45%. Jalan dengan perkerasan lentur menggunakan aspal sebagai pengikat agregat sehingga banyak diminati daripada perkerasan kaku. Infrastruktur jalan membutuhkan pemeliharaan bersifat berkelanjutan. Penggunaan kemasan plastik tidak bisa dipisahkan dalam kehidupan sehari-hari. HDPE adalah polietilena berdensitas tinggi. Berdasarkan masalah jumlah sampah plastik bekas yang ada sekarang, penelitian ini diperlukan untuk mengetahui seberapa baik perkerasan menggunakan penggunaan jenis plastik HDPE sebagai limbah plastik campuran. Setelah menguji di laboratorium dan menganalisanya sesuai dengan Spesifikasi Umum Jalan Raya untuk komposisi normal tanpa campuran plastik 0%, kadar aspal yang memenuhi semua persyaratan diperkirakan tingkat aspal antara 5.6% - 6%. Dari hasil penelitian dengan 4 komposisi berbeda diperoleh komposisi konten aspal optimal campuran plastik HDPE 0%, 4%, 8% dan 12% yang memenuhi VIM dan Stabilitas diperoleh campuran plastik HDPE 8% optimal dengan kadar aspal optimal 4.45%.
