Abstract

Wastewater from the Sludge Treatment Plant (IPLT) often contains hazardous contaminants that can pollute water bodies if discharged without prior treatment. Wastewater treatment from the IPLT, especially the Oxidation Ditch outlet, can be carried out using one of the Advanced Oxidation Processes (AOPs), namely Fenton. This study aims to analyze the effectiveness of the Fotofenton method in the Oxidation Ditch outlet unit of the Keputih IPLT, Surabaya, on total coliform, COD, and TSS parameters. The total coliform removal percentage was 98%, the COD parameters were 82%, and the TSS parameters were 60% at a dose of FeSO4: H2O2 molar ratio of 1:15, UV lamp power of 20 watts, and sampling time of 60 minutes. This study demonstrates that the Fotofenton method can be an environmentally friendly solution for wastewater treatment from IPLT and can be applied as an advanced treatment stage to meet applicable quality standards.

Abstract

Population growth in Indonesia poses sanitation challenges, where Sewage Sludge Treatment Plants (IPLT) provide a solution for sewage waste treatment. However, IPLTs themselves still face obstacles in optimally removing contaminants such as ammonia, Total coliform bacteria, and COD. This study evaluates the effectiveness of advanced oxidation processes (AOPs) combining hydrogen peroxide and ultraviolet light (H2O2-UV) in degrading these three pollutants. The wastewater used in this study came from the outlet of the Final Clarifier unit. The experiments were conducted in a continuous reactor with varying concentrations of H2O2 (0.1%-0.7%) and UV light contact time (15-45 minutes). The results showed that the highest degradation efficiency was achieved at a H?O? concentration of 0.7% for 45 minutes, with a removal percentage of 99.24% for Total Coliform bacteria and 88.32% for Ammonia. However, for COD, the highest degradation efficiency was achieved at a concentration of 0.5% for 45 minutes with a removal percentage of 79.55%. These results prove that the H2O2-UV process is effective in degrading IPLT wastewater pollutant mixtures through the production of non-selective hydroxyl radicals (•OH).

Abstract

Office activities contribute to carbon dioxide (CO2) emissions through transportation, electricity consumption, waste generation, and LPG use. This study estimates CO2 emissions from a municipal government office in Kediri City using the IPCC Tier 2 methodology. Data were collected through vehicle counts, electricity consumption records, waste measurements, and interviews regarding LPG usage. The results show that electricity consumption is the dominant source of emissions, accounting for 51,120 kg CO2/year. Transportation activities contributed 882 kg CO2/year, while waste generation and LPG consumption generated 133.28 kg CO2/year and 161.17 kg CO2/year, respectively. Overall, energy use is the primary driver of emissions in office environments. These findings provide baseline data to support energy efficiency improvements and sustainable office management strategies to reduce carbon emissions .Contribution to Sustainable Development Goals (SDGs)SDG 13 – Climate ActionSDG 7 – Affordable and Clean EnergySDG 11 – Sustainable Cities and CommunitiesSDG 12 – Responsible Consumption and Production

Abstract

Industrial batik wastewater contains dyes and organic compounds at high concentrations,posing a potential threat to aquatic environments. This study aims to evaluate theeffectiveness of electrocoagulation using series and parallel monopolar electrodeconfigurations in reducing the levels of methylene blue, methyl red, and chemical oxygendemand (COD) in batik wastewater. The process was carried out in batches, withvariations in electrode configuration, voltages of 6 and 9 volts, and contact times of 30–90 minutes, using aluminium and iron electrodes. Color concentration analysis wasperformed using UV–Vis spectrophotometry, while COD was analyzed using the closedreflux method. The results showed that increasing the voltage and contact time improvedthe removal efficiency of all parameters. The parallel monopolar configuration providedthe best performance, with reduction efficiencies of 95.23% for methylene blue, 90.02%for methyl red, and 71.21% for COD. This was influenced by a more even currentdistribution and more effective coagulant formation. Parallel monopolarelectrocoagulation has the potential to be applied as an alternative method for treatingbatik wastewater.Contribution to Sustainable Development Goals (SDGs):SDG 3: Good Health and Well-BeingSDG 6: Clean Water and SanitationSDG 11: Sustainable Cities and CommunitiesSDG 14: Life Below Water

Abstract

This study examines the production of gluten-free gyoza wrappers from rice flour and mocaf with the addition of kappa carrageenan. Mocaf has a high amylopectin starch , causing the resulting product to have a sticky texture. Rice flour has a higher amylose than Mocaf, a property that correlates strongly with the ability of gluten-free dough to form a more stable and viscoelastic structure. Kappa carrageenan has the ability to form strong gels through the formation of double helix structures that associate with each other, thereby increasing the viscoelastic properties of food systems. In combination with starch, carrageenan interacts through hydrogen bonds and physical associations, producing a more stable composite gel network that is able to retain water and increase the flexibility and integrity of the dough structure. The purpose of this study was to determine the effect of rice flour and mocaf proportions with the addition of kappa carrageenan on the physicochemical and organoleptic characteristics of gluten-free gyoza wrappers, as well as the best treatment that produces gluten-free gyoza wrappers with organoleptic qualities that are close to or equal to commercial gyoza wrappers. This study used a completely randomized design (CRD) with a factorial pattern and three replicates. The first factor was the proportion of rice flour: mocaf (40:60; 50:50; and 60:40), while the second factor was the addition of kappa carrageenan (8, 10, and 12%). The data were analyzed using ANOVA and DMRT post-hoc test at a 5% confidence level. The best treatment was found in the rice flour: mocaf ratio (40:60) with 8% carrageenan addition, which produced a moisture of 53.72%; ash of 1.67%; starch of 41.97%; amylose of 9.46%; amylopectin of 32.51%; color of 2.56 (same as bone white with R); aroma of 3.04 (same as neutral with R) and texture of 4.04 (slightly more elastic than R).Contribution to Sustainable Development Goals (SDGs):SDG 6: Zero HungerSDG 3: Good Health and Well-being SDG 9: Industry, Innovation and InfrastructureSDG 11: Sustainable Cities and Communities

Abstract

Analogue nori is produced through cooking, molding, and drying processes using non- seaweed materials. This study utilized genjer leaves (Limnocharis flava) as the primary raw material due to their physical resemblance to commercial nori, with carrageenan added as a gelling agent to improve structural compactness and glycerol as a plasticizer to enhance moisture retention and flexibility. The objective was to determine the optimal carrageenan–glycerol proportion to obtain the best physicochemical qualities. A two-factor Completely Randomised Design with two replications was applied, consisting of carrageenan (1%, 1.5%, and 3%) and glycerol (1%, 1.5%, and 2%) concentrations. The optimal treatment (3% carrageenan and 2% glycerol) produced analogue nori with 14.44% moisture, 12.03% ash, 17.22% fat, 5.31% crude fiber, 5.74% dietary fiber, 40.57% antioxidant activity, 0.45 mg/kg lead, and a tensile strength of 0.0148 N/mm², indicating its potential as a functional nori alternative Contribution to Sustainable Development Goals (SDGs): SDG 2: Zero HungerSDG 3: Good Health and Well-BeingSDG 12 : Responsible Consumption and ProductionSDG 14 : Life Below Water

Abstract

Industrial batik wastewater contains total chromium, a heavy metal that can pollute aquatic environments. This study aims to evaluate the performance of a fixed-bed adsorption reactor in reducing total chromium concentrations in batik wastewater using coconut shell, corn cob, and zeolite adsorbents. The batik wastewater was obtained from Jemursari, Surabaya, with an initial total chromium concentration of 2.349-2.374 mg/L and a pH of 8. The bioadsorbents were prepared through carbonization at 500–600 °C, followed by chemical activation using 3 M H?PO?. The adsorption process was conducted continuously in a 5 L laboratory-scale fixed-bed reactor, with sampling times at 10, 40, 70, and 100 minutes. The results showed that total chromium removal efficiency increased significantly within the first 40 minutes for all adsorbents. The highest removal efficiency was achieved using zeolite at 87.8%, followed by coconut shell at 81.9% and corn cob at 73.1%. The superior performance of zeolite was attributed to its ion-exchange mechanism and physical properties, which are well-suited to continuous-flow systems.
