Abstract

Collusion in the construction services industry has proven to be detrimental to business competition. Collusive practices in the tender process hinder fair competition and result in significant economic losses. Companies involved in such collusion cooperate to manipulate bidding prices, avoid genuine competition, and influence tender outcomes to their advantage. As a consequence, companies not engaged in the collusion lose opportunities to secure contracts, while project costs escalate. Collusive tendering also has negative impacts on the quality of construction work. When companies collude to win tenders, they may disregard necessary quality and safety standards. This can lead to lower quality, unsafe projects, and increased infrastructure failure risks. Furthermore, collusive tendering creates an unfair environment for small and new companies attempting to enter the construction market. They often struggle to compete with large companies involved in the collusion, which have advantages in resources and experience. As a result, innovation and healthy competition in the construction services industry are hindered, and the market becomes dominated by a few major players. To combat collusive tendering, crucial steps need to be taken. Governments and procurement agencies should enforce strict and effective regulations to prevent and penalize dishonest practices. Transparency in the tendering process, rigorous scrutiny of collusive practices, and severe sanctions for violations must be implemented. Additionally, awareness and active participation from all stakeholders, including construction companies, governments, and the public, are essential in addressing collusive tendering. By eliminating collusive tendering, the construction services industry can foster fair competition, encourage innovation, improve the quality of work, and provide equal opportunities for all participating companies in the market.

Abstract

Public transportation plays a crucial role in urban mobility, especially in Jakarta, which faces various challenges such as traffic congestion and air pollution. TransJakarta, as a Bus Rapid Transit (BRT) system, is expected to be a solution for improving public transportation efficiency. However, passenger satisfaction with TransJakarta services is still influenced by the quality of bus stop facilities. This study aims to evaluate the impact of bus stop facilities on passenger satisfaction at three locations: Dukuh Atas 1 Bus Stop, Kampung Rambutan Bus Stop, and CSW Bus Stop. This research employs a quantitative approach with a descriptive method. Data were collected through questionnaires distributed to 185 respondents using a purposive sampling technique. The analyzed variables include accessibility, facilities, comfort, and security of bus stops. Data analysis was conducted using SPSS software with linear regression techniques to identify the relationship between bus stop facilities and passenger satisfaction. The research results indicate that the level of passenger satisfaction with TransJakarta shelter facilities at Dukuh Atas 1, Kampung Rambutan, and CSW shelters is generally in the fairly good category. Although some facilities have met passenger needs, several aspects, such as waiting area comfort, seat availability, and supporting facilities, still need improvement. Regression test results show that shelter facilities (X2) with a regression coefficient of 0.494 (t-value 5.687; significance 0.000) and shelter security (X3) with a regression coefficient of 0.473 (t-value 5.404; significance 0.000) have a significant impact on passenger satisfaction. Meanwhile, shelter accessibility (X1) and shelter comfort (X4) do not have a significant effect, with significance values of 0.569 and 0.780, respectively. To improve satisfaction, it is recommended to enhance shelter facilities such as ergonomic seating and real-time digital information boards, strengthen security systems with CCTV and optimal lighting, and conduct regular facility maintenance.
