Abstract

Introduction: Padang City Sanitation Working Group reported that 34.32% of households in Padang City use unsafe latrines with septic tanks that still do not meet the standards which potentially causes the wastewater from the septic tanks to contaminate the water of the wells. This study was conducted to analyse the effects of the septic tank condition on the microbiological quality parameters of the well-water, namely total coliform and Escherichia coli in Koto Tengah District, Padang. Methods: This study uses a quantitative research method. The data were collected by questionnaires, observation, interviews, and laboratory tests. Water sampling was collected by using the purposive sampling method where the water is taken from 20 wells originating from 10 coastal and 10 non-coastal areas. Results and Discussion: Total coliform was found in all samples, while Escherichia coli was found in two samples from coastal and five from non-coastal regions. The septic tank condition had a strong correlation with the total coliform concentration (r= -0.531) and affected the total coliform concentration in the well-water by 30.8%. However, the Escherichia coli concentration was not related and not affected by the condition of the septic tank (p>0.05). There was no significant difference in the concentration of the microbiological parameters in the coastal and non-coastal areas. Conclusion: The microbiological quality of the well-water did not comply with the quality standards to be used as water sources for the community. The total coliform concentration in the well-water was shown to have a close relationship with the septic tank's condition.

Abstract

Open defecation (OD) is a form of poor sanitation. OD can affect environmental health and public health. Community-led Total Sanitation (CLTS) is an approach that can be used to change community behavior by fostering a sense of disgust and shame towards OD practices so that the community can stop OD practices. This study is a form of CLTS triggering activity to eradicate OD in Nagari Tiku Utara. Evaluation of CLTS triggering activities was carried out to obtain community feedback after receiving triggering activities. This study was divided into several stages in the form of literature studies, procurement of triggering activity related to the eradication of OD practices, implementation of evaluation of triggering activity for the eradication of OD practices that have been carried out, and data analysis. Evaluation of the triggering activity was carried out using interviews and filling out questionnaires. The number of respondent samples taken was as many as the number of residents who attended the triggering activity related to the practice of eradicating OD in Nagari Tiku Utara, namely a sample of 30 respondents. The results of this study showed that the four components assessed after the triggering activities, namely community knowledge, community behavior, safe latrines components, and latrines observations, actually achieved achievements ranging from very good to sufficient.

Abstract

Operational activities in hospitals for providing medical services have the potential to produce wastewater containing various contaminants. These substances may pose environmental risks if not treated properly and in accordance with applicable standards. This study aims to evaluate the wastewater treatment system in a Class C Hospital in Banyuwangi by examining the effluent characteristics from the Wastewater Treatment Plant (IPAL) and the technical aspects of its treatment units. The research applied a descriptive quantitative approach through observations of the IPAL to identify wastewater sources and laboratory testing of effluent characteristics. The tested parameters included temperature, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammonia (NH₃-N), Total Suspended Solids (TSS), and oil and grease. Secondary data were obtained from regular IPAL test documentation. The effluent characteristics were compared to regulatory limits set in national regulations (Ministry of Environment and Forestry Regulation No. 68 of 2016 on Domestic Wastewater Quality Standards) and East Java Governor Regulation No. 72 of 2013 concerning Wastewater Quality Standards for Industrial and/or Other Business Activities. Most tested characteristics were within acceptable quality standards. However, the COD concentration exceeded the established limit. Observations indicated that most treatment units were in accordance with design criteria, except for the sedimentation unit. Therefore, the Class C Hospital in Banyuwangi needs to follow up and optimize the performance of its IPAL system, particularly in the sedimentation unit.Keywords :    Wastewater, evaluation; hospital, wastewater treatment; quality standard ABSTRAKAktivitas operasional rumah sakit dalam memberikan layanan medis berpotensi menghasilkan air limbah yang mengandung berbagai kontaminan. Kandungan tersebut dapat menimbulkan risiko terhadap lingkungan jika tidak dikelola dengan tepat dan sesuai standar yang berlaku. Penelitian ini bertujuan untuk mengevaluasi sistem pengolahan air limbah di salah satu Rumah Sakit Tipe C di Kabupaten Banyuwangi dengan menelaah karakteristik efluen dari Instalasi Pengolahan Air Limbah (IPAL) serta aspek teknis dari masing-masing unit pengolahannya. Metode penelitian yang digunakan adalah pendekatan kuantitatif deskriptif melalui observasi langsung terhadap IPAL guna mengidentifikasi sumber air limbah, serta pengujian laboratorium terhadap karakteristik efluen. Parameter yang diuji meliputi suhu, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Amonia (NH₃-N), Total Suspended Solids (TSS), serta minyak dan lemak. Data sekunder diperoleh dari dokumentasi hasil uji IPAL yang dilakukan secara berkala. Karakteristik efluen kemudian dibandingkan dengan ambang batas yang ditentukan dalam Peraturan Menteri Lingkungan Hidup dan Kehutanan No. 68 Tahun 2016 tentang Baku Mutu Air Limbah Domestik, serta Peraturan Gubernur Jawa Timur No. 72 Tahun 2013 tentang Baku Mutu Air Limbah Bagi Industri dan/atau Kegiatan Usaha Lainnya. Hasilnya menunjukkan bahwa sebagian besar parameter masih berada dalam batas standar, namun kadar COD tercatat melebihi ambang batas yang ditetapkan. Dari hasil observasi, sebagian besar unit pengolahan air limbah telah sesuai dengan kriteria desain, kecuali pada unit sedimentasi yang dinilai belum optimal. Oleh karena itu, Rumah Sakit Kelas C di Kabupaten Banyuwangi perlu melakukan evaluasi dan peningkatan terhadap sistem IPAL-nya, khususnya pada unit sedimentasi. Kata kunci : Air limbah,  baku mutu evaluasi,  IPAL, rumah sakit.
