Abstract

The wastewater from industrial laundries has a high quantity of contaminants from the washing process, as well as chemical additives. The current study assessed the efficacy of the coagulation/occultation/sedimentation (C/F/S) method to treat laundry wastewater in relation to physicochemical parameters of water quality with the goal of treating this type of wastewater. For this purpose, an experimental design was applied to the C/F/S step using the addition of coagulant Alum, coagulant Alum plus flocculant Superfloc, and coagulant HCA. Alum coagulant has removal efficiency of 52% for COD and 37% for phosphate. The use of alum coagulant and Superfloc flocculant produces COD removal efficiency of 60% and phosphate removal efficiency of 58%. The use of HCA coagulant shows a removal efficiency of 64% for COD and 78% for phosphate. This shows that using more HCA coagulant is more effective than using alum coagulant and Superfloc flocculant in laundry wastewater treatment.

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

Hospital hazardous waste (B3) management is crucial to avoid negative impacts on health and the environment. This community engagement aimed to improve B3 waste handling capacity in a regional hospital in East Java. Activities included site observation, technical discussions, SOP development, labeling training, and digital reporting via the Festronik system. Observations revealed issues in waste labeling, characterization, and logbook documentation. Interventions successfully improved labeling according to waste properties, developed technical SOPs, and fulfilled storage requirements based on Government Regulation No. 22 of 2021 Article 419 paragraph (4). Enhancements such as emergency response tools and updated signage further supported safe and compliant waste management. This program is expected to strengthen sustainable B3 waste governance in the healthcare sector.

Abstract

Permintaan energi global hingga saat ini masih sangat bergantung pada minyak bumi sebagai sumber utama. Meskipun tren dunia menunjukkan pergeseran menuju energi terbarukan, konsumsi minyak tetap tinggi, khususnya untuk sektor transportasi, industri petrokimia, dan pembangkit listrik di negara berkembang. Produksi minyak lepas pantai merupakan solusi teknis yang banyak digunakan untuk memanfaatkan cadangan minyak dan gas di laut dalam yang tidak dapat dijangkau oleh metode konvensional. Salah satu komponen penting dalam sistem bawah laut tersebut adalah Pipeline End Manifold (PLEM), yang berfungsi sebagai penghubung utama antara pipa bawah laut dan sistem penerima di permukaan atau unit pengolahan berikutnya. Penelitian ini bertujuan menganalisis potensi dampak lingkungan dari proses produksi PLEM menggunakan metode Life Cycle Assessment (LCA) serta memberikan rekomendasi perbaikan yang dapat mengurangi dampak tersebut. Analisis dilakukan menggunakan perangkat lunak OpenLCA 11.1.0 dengan basis data Greendelta serta metode CML-IA Baseline. Data masukan yang digunakan mencakup kebutuhan bahan baku dan bahan bakar, sedangkan data keluaran berupa produk, limbah, dan emisi yang dihasilkan selama proses produksi. Hasil penelitian menunjukkan bahwa proses produksi PLEM menghasilkan dampak lingkungan sebesar 0,0360126 kg PO₄ eq untuk kategori eutrofikasi, 0,00080028 kg C₂H₄ eq untuk oksidasi fotokimia, dan 2.573,30034 kg CO₂ eq untuk pemanasan global (GWP100a). Rekomendasi perbaikan yang dapat dilakukan adalah mengurangi limbah padat dengan mendaur ulang sisa baja melalui proses Electric Arc Furnace (EAF) guna meningkatkan efisiensi material dan menurunkan dampak lingkungan.
