Abstract
Rumah Sakit ABC merupakan salah satu fasilitas pelayanan kesehatan yang menggunakan air dalam jumlah besar. Rumah Sakit ABC menghasilkan limbah cair yang mengandung pathogen berbahaya seperti bakteri, virus dan jamur yang apabila tidak diolah dengan benar dapat mengakibatkan penyakit dan infeksi pada pasien, staf rumah sakit, dan masyarakat umum.
Pengolahan air limbah di Instalasi Pengolahan Air Limbah Rumah Sakit ABC menggunakan dua sistem IPAL yaitu IPAL sistem biofilter dan IPAL sistem lumpur aktif.
Dalam proses pengolahan air limbah tentunya tidak terlepas dari risiko kegagalan yang tentunya dapat menimbulkan kerugian bagi aktivitas rumah sakit, Masyarakat sekitar dan
lingkungan. Kajian penelitian ini dilakukan untuk mengidentifikasi dan menganalisis potensi kegagalan dalam proses pengolahan limbah cair Rumah Sakit ABC menggunakan
metode fishbone dan Failure Mode and Effect Analysis (FMEA). Identifikasi penyebab kegagalan dilakukan dengan menggunakan metode fishbone untuk menemukan akar penyebab permasalahan yang menjadi potensi kegagalan sistem. Selanjutnya dilakukan
perhitungan Risk Priority Number (RPN) untuk potensi kegagalan berdasarkan nilai severity (tingkat keseriusan kegagalan), occurrence (tingkat frekuensi terjadinya kegagalan), dan detection (tingkat kontrol mencegah kegagalan) dengan metode Failure Mode and Effect Analysis (FMEA).
Berdasarkan hasil perhitungan nilai RPN, didapatkan nilai RPN tertinggi terdapat pada koefisien resirkulasi lumpur aktif, rasio F/M dan hasil uji laboratorium. Secara keseluruhan, nilai RPN tertinggi terdapat pada koefisien resirkulasi lumpur aktif dengan nilai 125, dimana pada IPAL Lumpur Aktif Rumah Sakit ABC tidak dilakukan resirkulasi lumpur. Dampak kegagalan tersebut adalah penurunan efisiensi pengolahan. Upaya meminimalisasi risiko kegagalan yang dapat dilakukan yaitu melakukan pemantauan debit air limbah yang masuk ke setiap unit pengolahan, mengevaluasi desain bangunan IPAL agar sesuai dengan kriteria desain, melakukan evaluasi dan perbaikan untuk hasil uji laboratirium secara rutin, dan membuat pipa resirkulasi untuk lumpur aktif.
============================================================
The ABC Hospital is one of the health care facilities that uses large amounts of water. The ABC Hospital produces wastewater containing dangerous pathogens such as bacteria,
viruses and fungi which if not treated properly can cause disease and infection in patients, hospital staff, and the public. Wastewater treatment at the ABC Hospital Wastewater Treatment Plant (WWTP) uses two systems, namely the biofilter system and the activated sludge system. In the
wastewater treatment process, of course, it is inseparable from the risk of failure which can certainly cause losses to hospital activities, the surrounding community and the environment. This research study was conducted to identify and analyze potential failures in the ABC Hospital wastewater treatment process using the fishbone method and Failure Mode and Effect Analysis (FMEA). Identification of the causes of failure is carried out using the fishbone method to find the root causes of problems that are potential system failures. Furthermore, the Risk Priority Number (RPN) calculation is carried out for potential failures based on the severity value (the level of seriousness of failure), occurrence (the level of frequency of failure), and detection (the level of control to prevent
failure) using the Failure Mode and Effect Analysis (FMEA) method.
Based on the results of the RPN value calculation, it was found that the highest RPN value was found in the activated sludge recirculation coefficient, F/M ratio and laboratory
test results. Overall, the highest RPN value is found in the activated sludge recirculation coefficient with a value of 125, where in the ABC Hospital Activated Sludge WWTP no
sludge recirculation is carried out. The impact of the failure is a decrease in processing efficiency. Efforts to minimize the risk of failure that can be done are monitoring the wastewater discharge into each treatment unit, evaluating the WWTP building design so that it is in accordance with the design criteria, evaluating and improving laboratory test results regularly, and making recirculation pipes for activated sludge.
