Abstract

The Sutami Reservoir, located in Malang Regency, East Java, has moderate to severe levels of pollution. This pollution problem can reduce the water quality of the Sutami Reservoir, so it requires coordination from the agencies concerned to formulate water pollution control policies. The management agency for the Sutami Reservoir is the ‘Perum Jasa Tirta 1’ (PJT 1). The institutional analysis applied is the Interpretative Structural Modeling (ISM) method, to find out which agencies are key elements/factors. There are eleven agencies analyzed. Agencies that are included in the ‘Dependent’ sector are the Water Resources Public Works Office, the Tourism and Culture Office, the Livestock and Animal Health Office, the Population Control and Family Planning Office, and the rice farmer groups. Institutions in the ‘Linkage’ sector are the Food Crops, Horticulture, and Plantations Office and the Industry and Trade Office. Institutions in the ‘Independent’ sector that play a key role are the Environment Office, the Fisheries Office, Balai Besar Wilayah Sungai Brantas, and the floating net cage fish farmer group. These four agencies are the key elements that have a big driving power so that more in-depth coordination needs to be carried out for the formulation of policies and regulations for water quality control.

Abstract

Anaerobic Baffled Reactor (ABR) systems have only been utilized to reduce pollutant compounds in wastewater. Anaerobic conditions in ABR can double as an anode chamber in Microbial Fuel Cells (MFCs) which require anaerobic conditions. This study aims to test the ability of COD and TSS removal in tofu wastewater and the potential electricity generated from a combination unit of ABR and MFCs. The experiment was conducted on a laboratory scale using a continuous system for 96 hours. ABR reactor was made consisting of 5 compartments, where the second compartment was installed anode for MFCs. The cathode chamber of the MFCs system was made separate from the ABR reactor and filled with electrolyte solution. The anode chamber in the ABR and the cathode chamber are connected by a salt bridge. Electrodes used in MFCs are zinc as anode and copper as cathode. The removal of pollutants in tofu wastewater reached 55.85% for COD and 88.68% for TSS. The electrical potential of MFCs increases along with the increase of organic matter removal in wastewater. The electric voltage generated reached 0.94 V and electric current 0.40 mA. The power density generated in this MFCs system reached 94 mW/m².

Abstract

Canteen wastewater is a type of domestic effluent generated from cooking and dishwashing activities, typically containing high levels of organic matter such as fats, oils, food residues, and key pollutants like Total Suspended Solids (TSS) also Chemical Oxygen Demand (COD). This study evaluates the effectiveness of sweet orange peel (Citrus sinensis)-based bio-coagulant in removing TSS also COD from canteen wastewater. Orange peel was selected due to its bioactive compounds like a pectin, flavonoids, also organic acids, that contain hydroxyl and carboxyl functional groups vital for coagulation-flocculation processes. Treatment was conducted using the jar test method with variations in pH, dosage, and settling time. The results showed that the optimum condition was achieved at pH 3, a dosage of 2 g/L, also a settling time of 45 minutes, resulting in TSS removal efficiency of 30.48% and COD removal of 29.29%. These findings confirm the potential of orange peel as an eco-friendly natural coagulant for canteen wastewater treatment.

Abstract

This study aims to evaluate the potential of the aquatic plant Salvinia molesta in absorbing heavy metal nickel (Ni) from wastewater through phytoremediation. The process was assessed using Bioconcentration Factor (BCF) and Translocation Factor (TF) parameters. The experimental method was conducted by applying variations in leaf density and surface coverage of the plant in reactors containing nickel solution. Results showed that Salvinia molesta reduced Ni concentration by up to 85.50%, with the highest metal accumulation found in the roots. The maximum BCF value reached 1.68, and the TF was 0.905, indicating that the plant effectively absorbed Ni from water into roots, but only partially translocated it to the upper parts. Therefore, Salvinia molesta demonstrates potential as a phytoremediator for Ni-contaminated water, with root accumulation being the dominant mechanism.

Abstract

Biogas is a potential renewable energy source, but the content of impurity gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) reduces its quality and efficiency as a fuel. This study aims to analyze the effectiveness of the adsorption method using a combination of coconut shell activated carbon and natural zeolite in increasing methane (CH4) levels in biogas. The biogas used was produced from a cattle farm in Carangwulung Village. The variables tested included variations in the composition of activated carbon (C) and zeolite (Z) adsorbents with biogas flow rates (0.2; 0.4; and 0.6 L/min). The test was carried out with an adsorbent mass of 300 grams activated by KOH and the resulting pressure ranged from 9–13 mbar. The results showed that the adsorbent composition of 50C:50Z with a flow rate of 0.2 L/min gave the best performance. Under these conditions, CH4 levels could increase from 45% to 87%, where there was an increase in methane by 48%. The adsorption process at low flow rates provides optimal contact time between gas and adsorbent, thus increasing the efficiency of increasing CH4 levels. Thus, the combination of coconut shell activated carbon and natural zeolite at low flow rates is effective in improving biogas quality through the adsorption process.

Abstract

With the potential of the agricultural sector, Bojonegoro Regency certainly requires an abundant supply of clean water. To overcome this problem, the Bojonegoro Regency Government built reservoirs to protect clean water supply in several areas in Bojonegoro Regency. The utilization of existing embung in Bojonegoro is not limited to agriculture only, but also as a tourist spot. To date, there has been no research assessing the quality of water in reservoirs. Consequently, this study aimed to evaluate the water quality in three reservoirs located in Bojonegoro. This study employs qualitative analysis derived from the environmental laboratory water quality assessments conducted by Dinas Lingkungan Hidup Kabupaten Bojonegoro. The findings from the water analyses of Embung Bendo, Embung Mayangkawis, and Embung Babo reveal distinct conditions among the three locations. These variations are attributed to differing environmental factors that influence each site uniquely.

Abstract

The rising trend of working from anywhere has increased activity in cafeterias, which produce wastewater with high levels of organic matter and suspended solids. If discharged without treatment, this wastewater can pollute the environment and disrupt ecosystem balance. This study aims to evaluate the effectiveness of plant quantity and retention time in a constructed wetland system of the sub-surface flow type, using the emergent macrophyte wetland method with amazon sword plant (Echinodorus palaefolius) plants to reduce Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS) in cafeteria wastewater. Variations in plant quantity (12, 14, and 16 stems) were tested over a 16-day retention period. The results showed BOD removal efficiency ranging from 94.62% to 97.85%, while TSS reduction ranged from 73.3% to 97.8%, depending on the sampling time. In the best-case scenario (on day 4), the system reduced BOD from 185.9 mg/L to 6 mg/L and TSS from 150 mg/L to 3 mg/L, meeting the effluent quality standards for restaurant wastewater. This high efficiency is attributed to physical filtration through roots and substrate, as well as rhizospheric microbial activity supported by the roots of the Amazon sword plant (Echinodorus palaefolius).

Abstract

Penggunaan boiler memiliki peran yang sangat penting dalam menunjang proses produksi pada berbagai industri salah satunya industri kayu. Boiler dapat menghasilkan panas yang berasal dari perebusan air yang nantinya akan menghasilan uap panas. Uap panas yang dihasilkan nantinya akan dialirkan ke dalam berbagai unit produksi yang membutuhkan energi panas. Penelitian ini menganalisis emisi gas buang dari pembakaran limbah kayu pada boiler di salah satu industri pengolahan kayu di Gresik, Jawa Timur, dengan pendekatan perhitungan stoikiometrik. Kayu bakar yang digunakan memiliki komposisi kimia dominan berupa karbon (43,43%), oksigen (48,21%), dan hidrogen (6,58%). Proses pembakaran dianalisis berdasarkan neraca massa dan kebutuhan oksigen, untuk memperkirakan laju alir mol dan konsentrasi emisi yang dihasilkan. Hasil penelitian menunjukkan bahwa emisi yang dihasilkan, seperti partikulat (124,258 mg/Nm³), SO₂ (87,712 mg/Nm³), dan NO₂ (160,109 mg/Nm³), masih berada jauh dibawah ambang batas yang ditetapkan dalam Permen LH No. 7 Tahun 2007. Dengan demikian, proses pembakaran limbah kayu pada boiler ini dapat dikategorikan aman bagi lingkungan. Kata kunci: Boiler, Emisi, Stoikiometri
