Abstract

Non-revenue water is the main problem faced by Perumda Air Minum Kota Surakarta, with a water loss rate reaching 42.37% in 2022. The purpose of this study is to identify and control the physical water loss using the water balance method and infrastructure leakage index. Primary data was obtained through field visits to make direct measurements, while secondary data was obtained based on data from the Solo City Drinking Water Company. A water balance analysis was carried out to determine the physical water loss, which was then used to calculate the ILI. The results showed that the water distribution volume was 24,270,430 cubic metres and the physical water loss was 9,669,609 cubic metres. The ILI value illustrates the effectiveness of distribution network management in controlling water losses. The conclusion of this study highlights the importance of water-free control measures and reduction of physical water leakage/loss to improve the efficiency and operational quality of drinking water services in Surakarta City.

Abstract

In 2022, the energy cost of PT. Air Minum Bandarmasih Kota Banjarmasin will be Rp. 586/m3 while the national average energy cost was Rp. 363.45/m3. In 2023, IPA 2 Pramuka distributed 41,152,457 m3 at an energy cost of Rp. 479.13/m3. A key step in energy management is to conduct regular energy audits. Energy audits are conducted to assess pump efficiency and determine Specific Energy Consumption (SEC), which facilitates technical recommendations for energy management. The first results of the energy audit at the IPA 2 Pramuka distribution unit of PT. Air Minum Bandarmasih revealed a power factor (cos φ) of less than 0.85, which is detrimental to energy efficiency. The pump efficiency was 50-60%, indicating that minor pump adjustments were needed. In addition, the SEC in 2023 was slightly above 0.4 kWh/m3 (about 0.40094 kWh/m3). The proposed improvement measures were the repair of the pump and regular maintenance, as well as the installation of a capacitor bank to improve the energy efficiency of the distribution unit of IPA 2 Pramuka.

Abstract

Ciprofloxacin is an antibiotic commonly used for bacterial infections. It is found in significant concentrations in hospital outlet wastewater and the pharmaceutical industry. Nano zero-valent iron (nZVI) has strong reducing power, and MXene is known for its anti-corrosion. Achieving effective results in this adsorption process is influenced by several factors, such as pH. The point of zero charge is the pH at which the material's surface is electrically neutral.The pH pzc was measured by adding the material to a 0.01 M NaNO₃ solution with an initial pH of 2–12, shaking for 2 hours, leaving for 2 days, and measuring the final pH of each solution. The pH pzc on nZVI material is 4.25. The pHpzc of the MXene material is 2.8. The pHpzc on the nZVI-MXene material is 3.45. The pHpzc value on the nZVI-MXene material is lower than nZVI and higher than MXene. The presence of acid groups from MXene, which dominate the surface of the material, can cause the pHpzc value to be closer to the pHpzc value of MXene than nZVI but still higher than MXene due to the influence of the base group from nZVI. In addition to electrostatic interactions, other mechanisms exist during high pH reactions, such as interactions of active functional groups on the material's surface with adsorbates through chemical bonds.

Abstract

A preliminary energy audit is a crucial step in identifying potential energy savings and improving operational efficiency in pump systems within water treatment installations. This study aims to evaluate the energy efficiency of distribution pumps Q1, Q2, and Q3 at the Sunggal Water Treatment Plant (IPA Sunggal) operated by Perumda Tirtanadi, North Sumatra Province, through a preliminary audit. The methodology includes measuring flow rate, pressure, current, voltage, and power factor to calculate hydraulic power, input power, pump efficiency, and Specific Energy Consumption (SEC). Results show that pump Q1 unit 3 and pump Q2 unit 7 have efficiencies below 60%, with SEC values indicating energy inefficiency. Improvement recommendations are provided based on efficiency criteria, ranging from impeller adjustments to complete pump replacement. This audit serves as the initial step toward a comprehensive energy audit plan to support energy efficiency and sustainability in the water distribution system.
