Abstract

Flexible pavement utilises asphalt as a binding agent. The pavement layer transmits and distributes the weight from the road or flexible pavement uniformly onto the compacted subgrade. Damage to flexible pavement results from a confluence of multiple connected factors. The purpose of the study is to ascertain the thickness of flexible pavement layers and the various forms of flexible pavement. This research employs the 2017 Bina Marga approach, utilising predicted LHR data over the design life or LHRT, to ascertain the kind and thickness of flexible pavement layers, considering the CESA4 and CESA5 values. The 2044 LHRT value for Passenger Cars and Other Light Vehicles is 33,358.7; Class 5A is 6.2; Class 5B is 4.1; Class 6A is 17.1; Class 6B is 39.1; and Class 8 or non-motorized vehicles is 280.1. The CESA4 value derived from the LHRT value was 4021566.47, whereas the CESA5 value was 469755.421. The most preferred type and thickness of flexible pavement is asphalt with a granular foundation layer, namely AC – WC pavement type at 4 cm thickness, AC – BC at 6 cm thickness, and LFA Class A at 40 cm thickness.

Abstract

Construction work is an important part of economic growth. Procurement of construction goods and services is one of the factors for successful development. One method used in procurement of construction services is direct appointment. Based on this, the government issued Presidential Regulation No. 16 of 2021 and Presidential Regulation No. 12 of 2021 concerning procurement of construction goods and services. The purpose of this study is to determine the stages of the direct appointment process and to determine the impact of changes in presidential regulations on the process of direct appointment of construction service providers. Thus, it is hoped that it can provide policy recommendations that can increase the effectiveness of construction service procurement. The research method uses quantitative descriptive research. The sampling technique uses purposive sampling, with data taken from the Gunung Rajak Village Library Building Construction project and questionnaires distributed to service providers, service providers, and the Gung Rajak village community who understand service procurement. The data processing is descriptive and the questionnaire data processing uses a Likert Scale. The results of this study are that the process of direct appointment activities in the Gunung Rajak village library building construction project was carried out well and structured. Then the results of the questionnaire analysis with a Likert Scale showed the percentage value of the respondents' attitudes above 80%, with a small standard deviation value, namely (between 0.626 - 0.484), and an average Likert scale value of 4. These results indicate that Presidential Regulation No. 12 of 2021 is considered better in the process of direct appointment of construction service providers compared to Presidential Regulation No. 16 of 2018.
