Abstract

RSUD Dr. Soetomo Surabaya merupakan rumah sakit kelas A dan salah satu rumah sakit terbesar di wilayah Indonesia bagian timur. Dalam pengoperasiannya, rumah sakit menghasilkan limbah cair yang dapat mencemari lingkungan dan menyebabkan penyakit berbahaya bagi makhluk hidup. Sumber limbah cair dari RSUD Dr. Soetomo yaitu berasal dari dapur, laundry, rawat jalan atau poliklinik, Gedung Pusat Diagnostik Terpadu (GPDT), Graha Amerta, ruang perawatan, ruang otopsi atau kamar mayat, Gedung Bedah Pusat Terpadu (GBPT), IGD, serta farmasi. Sistem pengelolaan limbah cair dapat mengalami kegagalan fungsi sehingga perlu dilaksanakan identifikasi potensi mode kegagalan sistem IPAL. Kajian penelitian ini dilakukan untuk mengidentifikasi dan menganalisis potensi kegagalan sistem di IPAL dengan metode fishbone dan Failure Mode and Effect Analysis (FMEA). Identifikasi potensi penyebab kegagalan dilakukan dengan menggunakan metode fishbone untuk menemukan akar permasalahan yang menjadi potensi kegagalan sistem. Akar permasalahan kemudian dihitung nilai severity (tingkat keseriusan kegagalan), occurrence (tingkat frekuensi terjadinya kegagalan), dan detection (tingkat kontrol mencegah kegagalan) dengan metode Failure Mode and Effect Analysis (FMEA). Risiko dengan nilai terbesar berdasarkan penyebab kegagalan dinyatakan dalam Risk Priority Number. Nilai RPN berasal dari hasil perkalian severity, occurrence, dan detection. Hasil dari diagram fishbone diperoleh 5 aspek yaitu sumber daya manusia, metode, pengukuran, mesin, dan lingkungan yang mencakup faktor – faktor potensial penyebab kegagalan sistem pengoperasian IPAL. Analisis selanjutnya dengan metode FMEA didapatkan 3 peringkat nilai RPN tertinggi. Nilai RPN terbesar 125 yaitu faktor waktu tinggal di bak ekualisasi dan waktu tinggal di anaerobik biofilter. Peringkat selanjutnya adalah nilai RPN sebesar 100 yaitu faktor pelatihan dan sosialisasi petugas IPAL. Nilai RPN tertinggi ketiga yaitu 80 adalah faktor MLSS pada pengolahan SBR dan MBR, serta faktor perawatan blower. Upaya minimalisasi risiko untuk nilai RPN tertinggi yaitu melakukan pengurasan endapan di bak ekualisasi secara berkala, menambah volume di anaerobik biofilter, melakukan pelatihan dan sosialisasi kepada petugas IPAL secara berkala, melakukan seeding ulang untuk SBR dan MBR serta pengurangan atau pemberhentian pembuangan lumpur untuk SBR, dan melakukan perawatan blower selama sebulan sekali

RSUD Dr. Soetomo Surabaya is a class A hospital and one of the largest hospitals in eastern Indonesia. In its operation, the hospital produces liquid waste which can pollute the environment and cause dangerous diseases for living things. Source of liquid waste from RSUD Dr. Soetomo came from the kitchen, laundry, outpatient or polyclinic, Integrated Diagnostic Center Building (GPDT), Graha Amerta, treatment room, autopsy room or mortuary, Integrated Central Surgery Building (GBPT), Emergency Room, and pharmacy. The liquid waste management system can experience a malfunction, so it is necessary to identify the potential failure modes of the WWTP system. This research study was conducted to identify and analyze potential system failures in WWTP using the fishbone method and Failure Mode and Effect Analysis (FMEA). Identification of potential causes of failure is carried out using the fishbone method to find the root causes that become potential system failures. The root of the problem is then calculated for the severity (severity of failure), occurrence (frequency level of failure), and detection (level of control preventing failure) using the Failure Mode and Effect Analysis (FMEA) method. The risk with the largest value based on the cause of failure is stated in the Risk Priority Number. The RPN value is derived from the multiplication of severity, occurrence, and detection. The results of the fishbone diagram obtained 5 aspects, namely human resources, methods, measurements, machines, and the environment which includes potential factors causing the failure of the WWTP operating system. Subsequent analysis using the FMEA method obtained 3 rankings of the highest RPN values. The largest RPN value is 125, namely the residence time factor in the equalization tank and the residence time in the anaerobic biofilter. The next rating is the RPN value of 100, namely the training and socialization factor for WWTP officers. The third highest RPN value of 80 is the MLSS factor in SBR and MBR processing, as well as the blower maintenance factor. Efforts to minimize risk for the highest RPN value are periodically draining the sediment in the equalization tank, increasing the volume in the anaerobic biofilter, conducting training and outreach to WWTP officers on a regular basis, re-seeding for SBR and MBR and reducing or stopping sludge disposal for SBR, and Perform blower maintenance once a month
