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

Waste in the construction sector can be interpreted as loss or loss of various resources, namely material, time (related to labor and equipment), and capital, which is caused by activities that require direct or indirect costs but do not add value to the final product for service users This study was conducted on 64 respondents of building construction projects to determine the magnitude of losses due to ready mix concrete and its causes. Research using a questionnaire distributed through the online system. Of the 64 respondents produced 9.06 % which is the loss of ready mix concrete. The loss of Ready Mix concrete is 9.06% of the profit of Ready Mix Concrete. The validity test and reliability test produced 18 causative factors that caused the loss of ready mix concrete material waste. The biggest factors causing the loss of ready mix concrete are: lost due to being stolen, design changes, detailed drawing details and material orders that are not according to specifications and scattered when transported/moved.

Abstract

Change Order is a change that occurs in a construction project and cannot be avoided. Analysis of change orders on 10 West Java road construction projects examines how causes of change orders vary between upgrade projects versus maintenance projects, and types of construction (e.g. asphalt works, drainage, structures, and widening of road shoulders and grained pavements, restoration of conditions and minor works and daily work). This study also examines the risks posed by change orders by measuring the frequency and average percentage changes in project costs for various types of change orders. The research methodology is by looking for real data on road construction projects from 2014-2018. The result is that the main causes of change orders are consistently terminated contracts, owner-induced increases, and swelling of contract items, and contract negligence. The risk of a change order is the highest in the work: Hot Asphalt Mixture, Class S Upper, Laston Wear, Stonework, Class B Upper Base, Cement Concrete Pavement, Low quality f'c 15 MPa Concrete, Stone Pairs with Mortar, Embankment Choice, Thermoplastic Road Markings.
