Abstract

ABSTRAK Biaya energi total PT. Air Minum Bandarmasih Kota Banjarmasin melebihi rata-rata biaya energi nasional pada tahun 2022. Biaya energi yang tinggi disebabkan oleh kondisi topografi di Kota Banjarmasin yang relatif rendah dengan parameter kemiringan tanah hanya sekitar 0,13%. Kondisi tersebut menyebabkan pemanfaatan energi potensial (gravitasi) menjadi kurang optimal dalam proses distribusi air. Salah satu upaya dalam menurunkan biaya energi adalah dengan mengoptimalkan operasional pompa menjadi efisien. Tujuan penelitian ini adalah mengetahui efisiensi penggunaan energi dengan metode perbandingan variasi operasional pompa. Metode penelitian yang digunakan meliputi pengukuran parameter kelistrikan, debit dan tekanan pada pompa distribusi zona BTBS; analisis efisiensi pompa; dan analisis potensi penghematan yang dapat dilakukan. Fokus penelitian dilakukan pada jam operasional pompa pada periode minimum pemakaian air (pukul 23.00 – 05.00). Hasil penelitian menunjukkan biaya listrik dengan operasional menggunakan 2 pompa lebih hemat (sebesar Rp 18.493.621,41 per bulan) dibandingkan operasional menggunakan 1 pompa. Operasional menggunakan 2 pompa memberikan efisiensi pompa rata-rata sebesar 55%, dibandingkan dengan operasional 1 pompa (18,93%). Bahkan potensi penghematan masih bisa dilakukan dengan meningkatkan frekuensi putaran pompa pada suatu batasan tertentu atau dengan menambah 1 unit pompa kapasitas 500 m3/jam. Kata kunci: biaya energi, efisiensi pompa, operasional pompa  ABSTRACT The total energy cost of PT Air Minum Bandarmasih Banjarmasin City exceeds the average national energy cost in 2022. High energy costs are caused by the relatively low topographic conditions in Banjarmasin City with a land slope parameter of only about 0.13%. This condition causes the utilisation of potential energy (gravity) to be less than optimal in the water distribution process. One approach to reducing energy costs is by optimizing the operational efficiency of the pumps. This study aims to assess the energy efficiency by comparing variations in pump operations. The research methodology includes the measurement of electrical parameters, flow rate, and pressure in the BTBS zone distribution pumps; pump efficiency analysis; and potential savings analysis. The study focuses on the operational hours of the pumps during periods of minimal water usage (from 23:00 to 05:00). The results indicate that using two pumps is more cost-effective (saving Rp 18,493,621.41 per month) compared to operating with one pump. The two-pump operation yields an average pump efficiency of 55%, compared to 18.93% for the one-pump operation. Furthermore, there is still potential for savings by increasing the pump rotation frequency within certain limits or by adding an additional pump with a capacity of 500 m3/hour. Keywords:  energy cost, pump operation, pump efficiency

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

Biaya energi PT. Air Minum Bandarmasih pada tahun 2022 adalah sebesar Rp 532/m3 atau sekitar 39% dari total biaya operasional. Biaya energi tersebut lebih tinggi dibandingkan rata-rata biaya energi nasional (Rp 356,34/m3). Kondisi topografi tanah di Kota Banjarmasin yang relatif datar menyebabkan pemanfaatan energi potensial (gravitasi) menjadi kurang optimal dalam proses distribusi air minum. Salah satu upaya dalam menurunkan biaya energi adalah dengan penerapan elevated reservoir. Tujuan penelitian ini untuk mengetahui efisiensi energi penerapan elevated reservoir. Metode penelitian yang digunakan meliputi pengumpulan data primer dan sekunder; pengukuran parameter kelistrikan, debit dan tekanan untuk mengetahui efisiensi pompa; analisis penggunaan energi pada jaringan perpipaan eksisting; serta analisis penggunaan energi dan teknis pada jaringan perpipaan menggunakan elevated reservoir. Fokus penelitian adalah penerapan elevated reservoir yang beroperasi pada saat jam puncak tarif listrik atau waktu beban puncak (WBP) yaitu pada pukul 17.00-22.00 WITA. Hasil penelitian menunjukkan bahwa penggunaan listrik saat operasional menggunakan elevated reservoir lebih hemat sebesar Rp 434.883.265,-/ tahun dibandingkan dengan operasional menggunakan sistem pemompaan penuh. Ditinjau dari aspek teknis, tekanan air pada titik terjauh distribusi atau kritis masih memenuhi standar yang berlaku yaitu minimal 0,73 bar. Rata-rata tekanan terendah pada saat elevated reservoir beroperasi adalah sebesar 1,04 bar.

Abstract

The Indonesian Ministry of Industry stated that the production of batik cloth in 2017 reached an average of 500 million meters/year, which is equivalent to 25 million m3/year of water. With a large water demand in the production process, the batik industry can cause water pollution in waterbodies. The Dual-Chamber Microbial Fuel Cell (DCMFC) system can reduce organic pollutant levels in wastewater and produce electrical energy simultaneously. The purpose of this research was to study the effect of the addition of septage sludge and EM4 consortium on the power density produced by the DCMFC system and to study the effect of pH differences in the DCMFC system on the removal of COD. The effect of variations in the addition of sewage treatment plant sludge and EM4 on the production of electrical energy obtained results that are too large a difference. This result was attributed to several factors, including electric current, electric voltage, microorganism growth, and pH. The maximum power density in the EM4 variation was 297.61 mW/m2, the power density in the septage sludge variation was 287,26 mW/m2, and the control reactor power density was 185.99 mW/m2. The optimal pH for septage sludge and EM4 to degrade COD is about 7. In the DCMFC systems with EM4, MLSS values increased steadily from 1500 mg/L to 1800 mg/L regardless of pH. In the systems with septage sludge showed pH-dependent effects on MLSS (in the range of 1250-2400 mg/L), with pH 7 being detrimental. Biofilm formation on the anode increased over time in EM4 systems across all pH conditions, with notable growth in septage sludge systems observed at pH 6. The COD removal of the septage sludge and EM4 was highest at 33.83 and 40.76%, respectively.

Abstract

Modified membranes have gained significant attention due to their ability to enhance performance. Although membranes modified with TiO₂ nanoparticles have been studied, no research has specifically addressed their effectiveness in removing paracetamol contaminants, despite the widespread use of paracetamol and its potential contribution to increased waste production. Therefore, in this study, polyvinylidene fluoride (PVDF) membranes were modified with TiO₂ nanoparticles, providing new insights into the use of PVDF-TiO₂ specifically for paracetamol wastewater treatment. The results showed that TiO₂ nanoparticle-modified membranes exhibited better performance than unmodified membranes. The unmodified membrane had a lower performance rate (69.18%) compared to membranes modified with titanium isopropoxide (TTIP) at concentrations of 1 M (93.35%) and 0.5 M (90.05%). These results were supported by Scanning Electron Microscopy (SEM) analysis, which revealed that the unmodified membrane had an average pore size of 0.998 μm, whereas the membranes modified with TTIP at 1 M and 0.5 M had average pore sizes of 0.615 μm and 0.791 μm, respectively. The larger pores in the unmodified membrane allowed larger particles to pass through, reducing its filtration efficiency. These findings underscore the potential of TiO₂ nanoparticle-modified membranes for significantly enhancing water purification processes, particularly in the removal of pharmaceutical contaminants like paracetamol. Ultimately, this research could contribute to the development of more effective strategies for managing pharmaceutical waste in water sources, leading to improved environmental protection and public health.

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

Chromium ions is notably a hazardous heavy metal due to its toxic and carcinogenic nature, particularly in its hexavalent form, Cr(VI). One of the major Cr(VI) pollution source is from electroplating industry effluent, which may contain high concentrations that pose a risk of contamination of aquatic and soil ecosystems if not treated carefully. One of the alternative method known to be able to treat Cr(VI) wastewater is by using microbial fuel cell (MFC). This research focused on on the removal of Cr(VI) from synthetic electroplating wastewater using a 4L dual-chamber MFC under fed-batch condition, as well as investigating the impact of mixed liquor suspended solids (MLSS) and chemical oxygen demand (COD) concentrations to its performance. Observed parameters include the efficiency of Cr(VI) removal and power density. Septage sludge and acetate were both used as biomass and substrate source respectively. Based on this research, it can be concluded that the highest Cr(VI) removal efficiency and power density were achieved using specific MLSS and COD concentration that resulting in F/M ratio of 0,459 to 0,489 gCOD/gMLSS. From initial Cr(VI) concentration of 50 mg/L, the highest removal was obtained by MFC running with initial MLSS and COD concentrations of 3.500 and 1.500 mg/L respectively, achieving 62,17% over 312 hours. This setup also produced the highest power density of 48,22 mW/m².

Abstract

This study presents a comparative analysis of electrocoagulation for industrial wastewater treatment, evaluating the performance of aluminum (Al) and iron (Fe) electrodes. The research combines a systematic literature review with experimental trials on a pilot-scale system. Experimental data for Al electrodes revealed inconsistent performance, showing a significant COD reduction at high pollutant concentrations but a paradoxical increase at low concentrations. This increase is attributed to the formation of soluble organic complexes. Conversely, experimental trials with Fe electrodes demonstrated consistent COD reduction across a range of influent concentrations. Fe electrodes successfully reduced COD by 1010 mg/L (from 2660 mg/L) and 790 mg/L (from 3220 mg/L) on two separate days, confirming their superior stability. These findings validate the theoretical advantages of Fe over Al electrodes and underscore the importance of selecting electrodes based on wastewater characteristics. The study concludes that Fe electrodes provide a more reliable and stable solution for treating fluctuating industrial wastewater.
