Abstract: This research discusses the performance analysis of supervisory consultants in road construction projects in West Sumatra Province. The objectives to be achieved with this research are to identify factors that influence the performance of supervisory consultants on road construction projects in West Sumatra province, to analyze the dominant factors that influence the performance of supervisory consultants on road construction projects in West Sumatra province, and to obtain to improve the performance of supervisory consultants on road construction projects in West Sumatra province. In this research the author used a combined research method, namely by distributing questionnaires to respondents and conducting interviews with experts. The selected respondents were owners, namely the Department of Highways. Human Settlements and Spatial Planning of West Sumatra Province, consultants and contractors involved in Periodic Road Maintenance work activities in West Sumatra Province in the 2018 to 2023 Fiscal Year. The research results showed that there were 10 factors that influenced performance supervising consultants for a road construction project in West Sumatra Province and the dominant factors influencing it. Keywords: Performance. Analysis. Supervisory Consultants. Road Construction. West Sumatra Introduction Supervisory consultants are one example of a company that offers services in the production The quality of the services offered by supervisory consultants is not always assessed from the final product, namely in the form of a supervision report, but also from the supervision process during the implementation period. Customers in this context are parties who use products, in the form of services, offered by supervisory consultants. The customer, as the party who will enjoy and pay for the final results of the supervisory consultant service process, of course has his own perspective on what will be paid later (Abas, 2. Supervising consultants have a very important role in assisting project owners, especially in terms of monitoring construction implementation, both in terms of human resources, costs, time and project quality. The project management system capability of the field supervisory consultant is largely determined by the performance of each personnel, namely Team Leader. Engineer, and Suprof, in addition to the ability to manage all activities and resources (Yoneda, 2. The problem of involving supervisory consultants is very important in the implementation of road project construction. Supervising consultants assist in controlling the implementation of work, organizing the administration of construction service providers and can establish communication links between the owner, the contractor as the construction service provider and related agencies, so that each work implementation can produce good and quality productivity. This goal will be achieved if the performance of the supervisory consultant is able to adapt to field and work conditions (Yoneda. In the Department of Highways. Human Settlements and Spatial Planning of West Sumatra Province for the 2018 to 2023 Fiscal Year, many projects were found to be experiencing delays. 2018 there were 15 periodic maintenance packages for provincial roads, of the 15 work packages there were 3 work packages which experienced delays. In 2019 there were 61 periodic maintenance packages for provincial roads, there were 11 work packages which experienced delays, in 2020 there was 1 maintenance package Provincial Road Periodic, nothing is late. In 2021 there are 9 Provincial Road Periodic Maintenance packages, of these 9 work packages there are 2 work packages that are ISSN 2599-2081 EISSN 2599-2090 Fakultas Teknik UM Sumatera Barat Vol. 8 No. 2 Juni 2025 Rang Teknik Journal http://jurnal. id/index. php/RANGTEKNIKJOURNAL The cause of the delay was due to a lack of control from the supervising consultant during the implementation of the work, one of which was planning the use of materials, many of the materials used did not comply with the contract specifications, so the work was dismantled and Meanwhile, in 2022 there will be 12 provincial road periodic maintenance work packages, of these 12 work packages there are 3 work packages that are experiencing delays. The cause of the delay is the lack of experience of the supervisory consultant in supervising the project so that when problems occur, it takes a long time to make decisions. The supervising consultant does not check all quantities and volumes of measurement results for each job that has been completed properly, which results in inaccurate measurement results. For 2023 there are 6 road maintenance packages, but all can be completed on time (Source: Department of Highways. Cipta Karya and Spatial Planning, 2. In road construction projects in the province of West Sumatra, many problems were found in the field starting from delays in completing the work, apart from that the quality of the work was still low and did not comply with contract specifications. A development project will achieve success if there is reliable supervision of the progress of the development being implemented (Abas, 2. From the results of field observations and interviews with the Head of road maintenance for the Department of Highways. Cipta Karya and Spatial Planning of West Sumatra Province, one of the causes of project delays was related to the low performance of the supervisory consultant. It can be seen from the personnel placed in the field that many do not have the experience required in the offer. So when problems occur in the field they are slow in making decisions and do not provide much input during the implementation of the work. Apart from that, the problem that is often found in the field related to the low performance of supervisory consultants is that there are several consultants who have inadequate human resources or knowledge and do not master technical specifications in the field, implementation processes in the field, and project administration from contracts to PHO. Methods In this research the author used a combined research method, namely by distributing questionnaires to respondents and conducting interviews with experts. The respondents selected were the owners, namely the Department of Highways. Human Settlements and Spatial Planning of West Sumatra Province, consultants and contractors involved in Periodic Road Maintenance work activities in West Sumatra Province in the 2018 to 2023 Fiscal Year. using a non-probability sampling method . o-random sampl. , namely a saturated sampling technique. The research population consisted of consultants, contractors and owners. The number of respondents taken was 116 people. The selection of 116 respondents was due to the fact that 19 work packages were delayed. All personnel involved in the 19 work packages were used as research respondents, and were taken based on the perceptions of the owner, contractor and supervisory consultant. Figure 1.

The test results are shown in Table 1. above the values found KMO and Bartlett's Test of Sphericity is 0. 805 is above 0. 50 with a significance of 0. 000 which is below 0. 05, thus it can be stated that the sample has met the requirements and the analysis can continue. Second Objective Data Analysis Factor Analysis Measure Of Sampling Adequacy (MSA) The results of the factor analysis carried out obtained the Measure of Sampling Adequacy (MSA) Of the 49 variables, 47 variables produced MSA values above 0. 50 and there were 2 variables 50, namely X3. 21 and Of the 47 variables, the MSA value was above 0. All variables are valid and can be tested further for analysis. Communalities The next step is communalities, this research effort is to determine whether the variables can be grouped into one or several factors. So, the 47 variables that have been obtained from the Measure of Sampling Adequacy (MSA) value in the anti image matrix table will be simplified into one or several Based on the results of the analysis that has been carried out, a summary of the results is found as shown in Table 2.
