Abstract

Permasalahan pada Instalasi Booster KM. IV PDAM Tirta Musi Kota Palembang tercatat untuk rasio biaya listrik terhadap air terdistribusi mengalami kenaikan yaitu pada tahun 2021 sebesar Rp.259/m3 dan untuk laporan sampai bulan Mei 2022 sebesar Rp.308/m3. Konsumsi energi listrik instalasi tersebut mengalami kenaikan yang disebabkan umur ekonomis peralatan semakin berkurang menyebabkan penurunan kinerja pompa ditambah belum pernah dilakukan program audit energi, Perlu upaya peningkatan efisiensi energi yang dilakukan dengan menganalisis kondisi sistem distribusi eksisting kemudian dibandingkan dengan kondisi ideal untuk penghematan energi. analisis untuk pompa distribusi dilakukan dengan mengukur pemakaian energi oleh pompa dan efisiensi kinerja pompa (Aulia & Masduqi, 2021). Untuk kinerja jaringan perpipaan dianalisis dengan pengukuran sisa tekan di titik distribusi terjauh dan tertinggi. analisis hidrolis jaringan distribusi dengan melakukan pemodelan menggunakan EPANET 2.2. Hasil penelitian pada unit pelayanan KM. IV didapatkan Penurunan kinerja pompa dan tingginya konsumsi energi disebabkan oleh Pompa distribusi 1, 2, 3 dan 4 mengalami penurunan efisiensi kinerja menjadi 45-50%, sedangkan Pompa distribusi 1A, 2A, 1B dan 2B mengalami penurunan efisiensi kinerja menjadi kurang dari 40% ditambah kecepatan aliran air pada pipa distribusi utama unit pelayanan KM. IV kurang merata. Program peningkatan efisiensi energi yang dapat diterapkan dengan meningkatkan efisiensi kinerja pompa 1, 2, 3 dan 4 dengan melakukan rekondisi, perbaikan impeller, penyetelan Kembali dan penggantian pompa 1A, 2A, 1B dan 2B secara keseluruhan. Pemasangan pipa interkoneksi di daerah By pass Puntikayu meningkatkan kecepatan aliran pada pipa L28 dari 0,11 m/s menjadi 0,62 m/s.

Abstract

The increasing volume of domestic wastewater due to population growth poses significant environmental challenges, requiring effective treatment solutions. This study evaluated the effect of aeration on the efficacy of Constructed Wetland-Microbial Fuel Cell (CW-MFC) system in treating domestic wastewater using Equisetum hyemale plant. Reactors with dimensions of 50 cm × 24 cm × 20 cm with a volume of 9 liters of wastewater were tested for 18 days using 8 fed-batch reactors with gravel media and graphite electrodes, with NaCl as the electrolyte solution and KCl salt bridge. Lactobacillus plantarum was used to assess the removal efficiency of Biologycal Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and pH. The results showed the CW-MFC system significantly reduced pollutants, with the highest removal rates in reactors E7 and E8 in all treatments with BOD removal efficiences 90% and 91%, COD removal efficiencies of 93% and 91% on day 15.  TSS removal efficiency of E7 was 60% and E8 was 64%. Removal pH was 25-33%.  The highest bioelectricity production was highest in reactor E7 at 990.8 mW/m² on day 15 then gradually decreased to 520 mW/m² on day 18 due to the synergistic interaction of microbes, plant aeration, and electrochemical processes. This study concludes that CW-MFC with aeration with the addition of bacteria provides the best results and can be a sustainable solution in wastewater management and clean energy.

Abstract

Sustainable domestic wastewater treatment is urgently needed amid water scarcity and rising energy demands. The Constructed Wetland–Microbial Fuel Cell (CW-MFC) system integrates phytoremediation and bioelectricity production by electroactive microorganisms, yet previous studies rarely compared the synergistic effects of different plant species within this system, limiting its optimization. This study evaluated CW-MFC performance using three plant configurations (Pistia stratiotes, Eichhornia crassipes, and their combination) integrated with Lactobacillus plantarum at two concentrations (2×10⁸ CFU/mL and 5×10⁸ CFU/mL). The reactors were operated for 18 days under identical hydraulic conditions to assess BOD, COD, ammonia, and TSS removal efficiencies and power density generation. Results showed that Eichhornia crassipes achieved the highest pollutant removal efficiencies with COD reduction up to 82%, while the system with 2×10⁸ CFU/mL bacterial concentration produced the highest power density of approximately 1032 mW/m². Interestingly, lower bacterial concentrations yielded higher power outputs, possibly due to reduced microbial competition for electron transfer sites, enhancing electroactive bacteria performance. In conclusion, integrating Eichhornia crassipes with L. plantarum at 2×10⁸ CFU/mL optimizes both pollutant removal and bioelectricity production, confirming CW-MFC as an environmentally friendly technology with potential for sustainable wastewater treatment and renewable energy generation.

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.

Abstract

Used cooking oil underwent thermal and oxidative degradation due to repeated heating, resulting in increased peroxide levels and producing rancid odors, discoloration, and potential toxicity. In this study, the initial peroxide value of the used cooking oil was 56.42 meq O₂/kg, indicating significant oxidative degradation. The study evaluated the ability of activated sugarcane bagasse-bentonite (ASBB) and non-activated (SBB) composites to reduce peroxide values. Characterization was performed using SEM-EDX and FTIR, while adsorption efficiency was tested by varying the adsorbent dose (2–10 g) and treatment time (0–180 minutes). Peroxide reduction was analyzed using iodometric titration. The results showed that ASBB was more effective, with 10 g of ASBB and 180 minutes of treatment reducing the peroxide value by up to 82.3–84.5%.
