Abstract

ABSTRAK Penelitian ini mengevaluasi kinerja sistem elektrolisis air berbasis natrium hidroksida (NaOH) untuk memproduksi gas HHO dan menilai dampaknya terhadap konsumsi bahan bakar serta emisi gas buang. Pengujian dilakukan pada variasi bentuk elektroda (spiral dan pipa) serta volume larutan (200–220 ml). Hasil menunjukkan bahwa konfigurasi elektroda spiral–220 ml menghasilkan laju produksi gas tertinggi dan menurunkan konsumsi bahan bakar spesifik (Sfc) dari 0.074 menjadi 0.049 kg/Hp·jam. Emisi CO turun dari 2.394% menjadi 0.526% dan HC dari 596.6 menjadi 299.6 ppm. Uji ANOVA mengonfirmasi perbedaan yang signifikan antarkelompok perlakuan (p < 0.05). Selain temuan eksperimental, naskah ini menyajikan tinjauan singkat potensi elektrolit alami (NaCl/air laut) dalam kerangka keberlanjutan, berikut catatan risiko evolusi klorin dan korosi serta rekomendasi praktik keselamatan. Studi ini belum menghitung neraca energi bersih dan emisi NOx; keduanya diusulkan sebagai tolok ukur lanjutan. Temuan menegaskan bahwa NaOH efektif meningkatkan efisiensi dan menurunkan emisi, sementara elektrolit alami berpotensi sebagai alternatif berbiaya rendah dengan pengendalian risiko yang tepat. Kata kunci: ANOVA, elektrolit alami, emisi, HHO, konsumsi bahan bakar spesifik, NaOH  ABSTRACT  This study evaluates the performance of a sodium hydroxide (NaOH)–based water electrolysis system for producing HHO (oxyhydrogen) gas and assesses its effects on fuel consumption and exhaust emissions. Experiments were conducted using two electrode geometries (spiral and tube) and two electrolyte volumes (200–220 mL). The spiral electrode with a 220 mL electrolyte volume yielded the highest gas production rate and reduced the specific fuel consumption (Sfc) from 0.074 to 0.049 kg/HP·h. Carbon monoxide (CO) decreased from 2.394% to 0.526%, while hydrocarbons (HC) fell from 596.6 to 299.6 ppm. ANOVA confirmed statistically significant differences among treatments (p < 0.05). In addition to the experimental findings, the manuscript presents a brief review of the potential of natural electrolytes (NaCl/seawater) in a sustainability context, including risk notes on chlorine evolution and corrosion and recommended safety practices. This study did not compute a net energy balance or measure NOx; both are proposed as future benchmarks. The results indicate that NaOH is effective in improving efficiency and reducing emissions, while natural electrolytes remain a low-cost alternative when risks are appropriately managed. Keywords:  ANOVA, emissions, HHO, NaOH, natural electrolytes, specific fuel consumption

Abstract

ABSTRAK Acid Mine Drainage (AMD) is a major environmental concern in coal mining, particularly in Indonesia where surface mining is widely practiced. The exposure of sulfide minerals to water and oxygen leads to the formation of acidic, metal-laden leachate that poses significant risks to water resources, soil quality, and human health. Conventional treatment methods are often expensive and unsustainable, highlighting the need for preventive approaches. This study aims to predict and minimize AMD formation using the Free Draining Column Leach (FDCL) test under simulated wet-dry cycles. Various configurations of Potentially Acid Forming (PAF) and Non-Acid Forming (NAF) materials were tested, with the addition of biochar and zeolite as amendment layers. Static tests, including paste pH, NAG pH, NAPP, and Acid-Base Accounting (ABA), were used to classify the acid-generating potential of the samples. X-ray Diffraction (XRD) was conducted to assess mineral composition, and leachate was analyzed for pH and Total Dissolved Solids (TDS). Results showed that Scheme 3 (PAF–NAF–PAF) had the highest acid generation potential (pH < 4), while Schemes 4 and 5, which included biochar and zeolite, maintained neutral to alkaline conditions and lower TDS. These findings demonstrate the potential of local materials to reduce AMD risks and emphasize the importance of early prevention strategies. The FDCL method offers a valuable tool for improving mine waste management in alignment with sustainable mining practices. Keywords: Acid mine drainage; FDCL test; AMD prediction; biochar; zeolite; mine waste management

Abstract

The performance assessment of the Wolo Irrigation Area (WIA) is crucial for ensuring efficient water management and sustainable agricultural productivity. This study evaluates WIA’s operational performance using the e-PAKSI or eA-AMPIS application as a digital platform designed for integrated irrigation performance monitoring. The assessment results show a performance index of 60.44%, indicating that several functional aspects require improvement. Unlike previous studies that relied solely on manual field evaluation, this research integrates digital data collection through electronic Performance Assessment and Irrigation System Information (e-PAKSI) to provide more accurate, real-time, and traceable performance indicators. The findings highlight the need for targeted management strategies focusing on infrastructure maintenance, operational efficiency, and community-based institutional strengthening. Implementing these strategies can enhance WIA’s functionality and support sustainable irrigation management in similar regional systems.

Abstract

ABSTRAK Hidrogen merupakan salah satu sumber energi potensial yang berkelanjutan dan bersih dengan kepadatan energi tinggi (140 MJ/kg). Abu berat merupakan limbah padat yang sulit larut dan menguap serta memerlukan pengolahan khusus. Pembakaran batubara di PLTU menghasilkan limbah berupa fly ash dan bottom ash dalam jumlah besar setiap tahunnya, yang berpotensi mencemari lingkungan jika tidak dimanfaatkan dengan tepat. Pada tahun 2021, Indonesia menghasilkan sekitar 9.7 juta ton limbah abu terbang (fly ash dan bottom ash). Tujuan dari penelitian ini adalah memanfaatkan kandungan 53-70 Si pada abu terbang untuk meningkatkan gas hidrogen dengan menambahkan zat pereduksi aluminium dan memvariasikan konsentrasi katalis KOH. Katalis KOH digunakan karena KOH menghasilkan lebih banyak gas hidrogen dibandingkan NaOH. Penelitian ini dilakukan dengan mereaksikan 3 sampai 6 gram aluminium: silikon dengan air suling dan katalis KOH 4,5 M - 5M dan ini dilakukan pada temperatur 50°C selama 15 menit. Dengan berat auminium:silicon 6 gran dan konsentrasi KOH 5.5 M menghasilkan produksi gas hydrogen sebesar 68%. Semakin banyak penggunaan aliminium:silikon dan semakin tinggi konsentrasi KOH yang digunakan maka gas hidrogen yang dihasilkan akan semakin banyak. Kata kunci: Aluminium, bottom ash batubara, hidrogen, silikon ABSTRACT Hydrogen is a potential sustainable and clean energy source with a high energy density (140 MJ/kg). Heavy ash is a solid waste that is difficult to dissolve and evaporate, requiring special treatment. In 2021, Indonesia produced approximately 9.7 million tons of fly ash and bottom ash. This study aims to utilize the 53–70% Si content in fly ash to enhance hydrogen gas production by adding aluminum as a reducing agent and varying the concentration of KOH catalyst. KOH was selected as the catalyst because it generates more hydrogen gas compared to NaOH. The experiment was carried out by reacting 3 to 6 grams of aluminum:silicon with distilled water and KOH catalyst at concentrations ranging from 4.5 M to 5 M, maintained at 50°C for 15 minutes. The highest hydrogen gas production of 68% was obtained with 6 grams of aluminum:silicon and a KOH concentration of 5.5 M. The results showed that increasing the amount of aluminum:silicon and the concentration of KOH led to greater hydrogen gas generation. Keywords:  Aluminum, coal bottom ash, hydrogen, silicon

Abstract

The use of Black Soldiet Fly (BSF) in processing organic waste offers numerous benefits, including significant waste volume reduction, transformation of waste into value-added products such as organic fertilizers, livestock feed, and fish feed, as well as supporting the implementation of a circular economy. However, organic waste processing practices in BSF larvae or what is more widely known as maggot with maggot houses often face challenges, particularly in terms of funding. Financial factors are crucial elements that determine the operational sustainability of such waste management systems. This study aims to analyze the financial conditions and operational feasibility of Rumah Maggot Cimincrang and Imah Maggot Bantaran. The study employs the Net Present Value (NPV) method, which calculates the present value of total net revenues after deducting costs over a specific period. NPV serves as a tool to assess the financial feasibility of an activity. If the NPV is positive, the activity is considered financially feasible and profitable. The results indicate that the operational feasibility of Rumah Maggot Cimincrang can be achieved through product diversification, such as producing maggot meal and maggot oil, alongside optimizing marketing efforts via digital platforms like e-commerce with a NPV of IDR 161,769,698. Meanwhile, Imah Maggot Bantaran, which operates on a community-based model, is already financially viable with an NPV of IDR 4,333,190,208. However, further efforts are needed to enhance operational consistency, ensuring the production of sustainable products over the long term.

Abstract

Obi Island in North Maluku Province, Indonesia, has undergone significant land cover changes due to the expansion of nickel mining activities, especially since official operations began in 2010; the conversion of built-up land and vegetated areas into mining and settlement zones has increased pressure on land carrying capacity and contributed to more frequent flooding during the rainy season. This study uses spatial analysis based on Landsat 5 (1995) and Landsat 8 OLI (2025) satellite imagery to map land cover changes over three decades. The results show an increase in built-up land area from 448.84 hectares to 698.67 hectares, as well as the emergence of a 4,963.67-hectare mining area in 2025, while open land, water bodies, and vegetation have significantly declined. These findings demonstrate the direct impact of mining activities on landscape dynamics and the local environment, necessitating sustainable management and mitigation measures to maintain ecological balance and reduce the risk of related disasters.Keywords: LULC, Nickel Mining, Obi island

Abstract

ABSTRAK Limbah cair laundry menjadi salah satu masalah pencemaran lingkungan karena mengandung deterjen, fosfat, surfaktan, dan bahan kimia lain yang berpotensi menurunkan kualitas perairan. Aktivitas ini dilakukan setiap hari sehingga membutuhkan pengolahan secara tepat agar dapat mengurangi beban pencemar di badan air. Salah satu pengolahan limbah cair laundry adalah dengan metode koagulasi-flokulasi menggunakan koagulan aluminium sulfat dan flokulan poliakrilamida. Tujuan penelitian ini adalah untuk mengetahui pengaruh variasi flokulan poliakrilamida dan menentukan dosis optimum flokulan terhadap persentase penyisihan kontaminan pada limbah cair laundry. Proses koagulasi-flokulasi limbah cair laundry dilakukan menggunakan metode jar test pada 1000 mL air limbah dengan pengadukan cepat 120 rpm selama 10 menit dan pengadukan lambat 30 rpm selama 20 menit. Dosis koagulan aluminium sulfat yang digunakan sebesar 4 g/L dan variasi dosis flokulan poliakrilamida yang digunakan 0.1, 0.2, 0.3, 0.4, 0.5, dan 0.6 g/L. Penambahan flokulan poliakrilamida tidak berpengaruh pada perubahan pH karena penurunan pH lebih dipengaruhi oleh penambahan koagulan aluminium sulfat. Persentase penyisihan tertinggi pada parameter TSS, COD, fosfat, dan MBAS diperoleh dengan dosis optimum flokulan sebesar 0.6 g/Ldengan masing-masing persentase penyisihan sebesar 96.52%, 45.65%, -37.23%, dan 88.36%. Kata kunci: Aluminium sulfat, flokulan, limbah cair laundry, poliakrilamida ABSTRACT Laundry wastewater is one of the environmental pollution problems because it contains detergents, phosphates, surfactants, and other chemicals that have the potential to reduce water quality. This activity is carried out every day so it requires proper processing to reduce the pollutant load in water bodies. One of the laundry wastewater treatment methods is the coagulation-flocculation method using aluminum sulfate coagulant and polyacrylamide flocculant. The purpose of this study was to determine the effect of variations in polyacrylamide flocculants and determine the optimum flocculant dosage on the percentage of contaminant removal in laundry wastewater. The coagulation-flocculation process of laundry wastewater was carried out using the jar test method on 1000 mL of wastewater with fast stirring at 120 rpm for 10 minutes and slow stirring at 30 rpm for 20 minutes. The aluminum sulfate coagulant dosage used was 4 g/L and the polyacrylamide flocculant dosage variations used were 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6 g/L. The addition of polyacrylamide flocculant did not affect the pH change because the decrease in pH was more influenced by the addition of aluminum sulfate coagulant. The highest removal percentages for TSS, COD, phosphate, and MBAS parameters were obtained with an optimum flocculant dose of 0.6 g/L with removal percentages of 96.52%, 45.65%, -37.23%, and 88.36%. Keywords: Aluminum sulfate, flocculant, laundry waste, polyacrylamide
