Abstract

To fulfill the needs for clean water in Pekanbaru City and Kampar Regency Riau, Perusahaan Daerah Air Minum(PDAM)/Drinking Water Regional Enterprise (DWRE) in collaboration with an investor company is building piping network infrastructure known as the Pekanbaru – Riau Sistem Penyediaan Air Minum (SPAM)/Drinking Water Supply System (DWSS). This SPAM/DWSS has an important role in fulfilling the needs for clean water in the community. However, its operational sustainability is highly dependent on the ability of potential customers to pay for the services (willingness to connect). This study aims to analyze factors influencing the willingness to connect for prospective customers of SPAM/DWSS Pekanbaru – Kampar by using the binary logistic regression method. The independent variables analyzed include economic, social, and demographic factors, such as age, occupation, household income, education level, and customer perception of water tariffs. The data were collected through a survey conducted by RH Consultants to 2,000 respondents of domestic customers and 1,500 respondents of commercial and industrial customers to determine the most significant factors influencing the willingness to connect. The results showed that household income has a significant influence on the willingness to connect for potential customers. These findings provide insights for SPAM/DWSS managers and local governments in designing more equitable and sustainable tariffs and policies.

Abstract

The acquisition process in the construction industry requires careful evaluation of potential targets, particularly regarding financial performance. Data-driven segmentation has become a strategic method to group companies based on financial characteristics, enabling objective acquisition decisions. This study applies the K-Means Clustering algorithm to segment construction companies using key financial indicators, including P/E ratio, Price-to-Book Value (Price to BV), D/E ratio, ROA, ROE, and NPM. Secondary data from financial statements of construction companies listed on the Indonesia Stock Exchange (IDX) during 2023–2024 were analyzed. Five clusters were identified, reflecting varying levels of financial performance and risk. Among the 23 companies studied, 18 experienced a decline in performance. Notably, PT Totalindo Eka Persada Tbk showed the most significant decline, with a high D/E ratio and negative NPM, suggesting it as a potential acquisition target at a lower price. Post-acquisition, financial and operational restructuring, governance improvements, project diversification, and cost-efficiency measures are recommended. Each cluster presents distinct characteristics relevant for acquisition strategy; for example, high-profitability but low-solvency clusters may attract high-risk investors. This study demonstrates how data mining techniques support corporate due diligence and strategic decision-making, offering a structured approach to identify companies with differing financial strengths and weaknesses. The findings contribute to advancing quantitative approaches in acquisition planning, highlighting how clustering techniques can enhance objective evaluation and strategic alignment in mergers and acquisitions.

Abstract

This study is intended to analyze the influence of quality, quantity, continuity, and service of Sistem Penyediaan Air Minum (SPAM)/Drinking Water Supply System (DWSS) products on customer satisfaction, which has an impact on the amount of piped water absorption. This study uses a quantitative approach with a survey method and Structural Equation Modeling–Partial Least Squares (SEM-PLS). Data were obtained through the distribution of questionnaires by the company’s QHSE Bureau to SPAM/DWSS customers, namely Perusahaan Daerah Air Minum (PDAM)/Drinking Water Regional Enterprise (DWRE). The respondents are PDAM/DWRE entities that have become partners of the company and cooperate in operating the water supply business. The variables studied include water quality (color, taste, odor, and pH), quantity (water capacity fulfillment and distribution), continuity (the ability to provide water at the required capacity and maintain its distribution processes), and service (ease of communication and responsiveness to the instructions given). The results of the study show that the X1 variable of product quality has a positive and significant influence on customer satisfaction, which also has a significant effect on the amount of piped water absorption. Product quality is the most dominant factor influencing satisfaction, and it increases the amount of piped water absorption. This indicates that customer considerations in SPAM/DWSS services are not only related to the quantity of water received and the consistency of distribution but also to the quality of the water consumed.
