Abstract

Inkubator Bisnis (Inbis) Permata Bunda merupakan suatu kompleks bangunan kewirausahaan bagi penyandang disabilitas di kota Bontang, Kalimantan Timur. Inbis Permata Bunda ini mempunyai sistem IPAL domestik sendiri untuk mengolah limbah domestik yang dihasilkan dari kompleks bangunan tersebut. Proyek IPAL Inbis Permata Bunda ini dirancang dan bekerja sama dengan PT. Pupuk Kaltim dalam program kerja CSR untuk perbaikan lingkungan. IPAL pada Inbis Permata Bunda ini baru selesai dibuat pada tahun 2019, dan mengalami redesain pada tahun 2020 dan baru difungsikan kembali selama sekitar dua bulan. IPAL Inbis Permata Bunda ini mempunyai 6 unit pengolahan. Unit pertama yaitu unit filtrasi. Saringan ini terdiri dari pasir, ijuk, batu, dan arang. Unit kedua merupakan bak pengendap awal. Unit ketiga adalah unit reaktor biofilter anaerob. Unit keempat adalah unit reaktor biofilter aerob yang dilengkapi dengan proses areasi menggunakan blower udara. Unit kelima bak pengendapan, berfungsi untuk memisahkan atau mengendapkan kotoran padatan tersuspensi (TSS) yang ada di dalam air limbah agar air olahan IPAL menjadi jernih. Unit keenam merupakan bak pembuangan untuk menampung limbah sebelum dibuang ke badan air. Karena IPAL ini masih baru berjalan setelah mengalami redesain, maka diadakan evaluasi untuk mengetahui kinerja IPAL ini. Maka dari itu dirasa perlu untuk dilakukan pengujian efisiensi dari IPAL tersebut agar memastikan kinerja IPAL ini kembali optimal dan sesuai dengan standar. Tujuan penelitian kali ini untuk menginventarisasi air limbah, mengevaluasi kinerja IPAL, dan melakukan review desain untuk memberikan rekomendasi IPAL Inbis Permata Bunda. Metode penelitian yang digunakan adalah metode penelitian evaluatif formatif. Penelitian dilakukan pada bulan November 2020 hingga februari 2021. Evaluasi kinerja IPAL didasarkan pada inventarisasi sumber air limbah, evaluasi proses pengolahan, dan evaluasi outlet air limbah. Sampling dilakukan dengan metode grab sampling. Uji laboratorium dilakukan untuk memperoleh data dan selanjutnya akan dilakukan perhitungan kinerja untuk mengevaluasi IPAL tersebut. Perhitungan kinerja akan dibandingkan dengan referensi standar desain tiap unit. Parameter yang dijadikan acuan adalah pH, BOD, COD, TSS. Fe, dan Pb Hasil penelitian diperoleh debit inlet rata-rata 1,65 m3/hari dan debit puncak 2 m3/dt. Bak Filtrasi dengan efisiensi removal BOD 13,8%, COD dengan nilai efisiensi removal 77%, TSS 34%, Fe 52%, dan Pb 0%. Bak pengendap pertama dengan efisiensi removal BOD -5%, COD -4%, TSS 28%, Fe 7,4%, dan Pb 0%. Bak biofilter anaerobic dengan efisiensi removal BOD 4%, COD 10%, TSS -6%, Fe 21%, Pb 0%. Bak aerasi dengan efisiensi removal BOD 56%, COD 70%, TSS 81%, Fe 0,6%, Pb 0%. Bak pengendap 2 dengan efisiensi removal BOD 61%, COD 72%, TSS 69%, Fe 33%, Pb 0%. Outlet air limbah yang dihasilkan dari IPAL Inbis Permata Bunda sesuai dengan baku mutu Permen LH No. 68 tahun 2016. Secara keseluruhan kinerja IPAL masih berjalan dengan baik namun secara efisiensi waktu pengolahan masih terlalu lama akibat debit yang terlalu kecil. Selain daripada itu, masih ada kebocoran pada beberapa bak pengolahan.

English Abstract

Permata Bunda Business Incubator (Inbis) is an entrepreneurial building complex for people with disabilities in the city of Bontang, East Kalimantan. Inbis Permata Bunda has its own domestic IPAL system to treat domestic waste generated from the building complex. The IPAL Inbis Permata Bunda project was designed and collaborated with PT. Pupuk Kaltim in its CSR work program for environmental improvement. The IPAL at Inbis Permata Bunda was only completed in 2019, and undergoes throguh redesign in 2020. IPAL Inbis Permata Bunda has 6 processing units. The first unit is the filtration unit. This filter consists of sand, palm fiber, stone and charcoal. The second unit is the initial settling basin. The third unit is an anaerobic biofilter reactor unit. The fourth unit is an aerobic biofilter reactor unit which is equipped with an acreation process using an air blower. The fifth unit of the settling basin functions to separate or settle suspended solids (TSS) in the waste water so that the IPAL processed water becomes clear. The sixth unit is a disposal basin to collect waste before it is discharged into water bodies. This WWTP has just been through redesigning, as the first design of the WWTP is not working properly and the effluent when tested by the lab is still not in accordance with the predetermined quality standards. Therefore, it is necessary to test the efficiency of the newly redesigned WWTP in order to ensure that this new WWTP's performance is back to optimal and in accordance with the standards. The aim of this research is to inventorized wastewater source, evaluate the performance of the WWTP, and conduct a design review to provide recommendations for the Inbis Permata Bunda WWTP. The research method used is a formative evaluative research method. The research was conducted from November 2020 to February 2021. The performance evaluation of WWTP is based on an inventory of wastewater sources, evaluation of treatment processes, and evaluation of wastewater outlets. Grab Sampling method is used to obtain water sample in the WWTP. Laboratory tests are carried out to obtain data and then the performance calculations will be carried out to evaluate the WWTP. Performance calculations will be compared with reference design standards for each unit. The parameters used as references are pH, BOD, COD, TSS. Fe, and Pb. The results showed that the average inlet discharge was 1.65 m3 / day and the peak discharge was 2 m3 / day. Filtration bath with removal efficiency of 13.8% BOD, COD with 77% removal efficiency, 34% TSS, 52% Fe, and 0% Pb. The first settling basin with removal efficiency of -5% BOD, -4% COD, 28% TSS, 7.4% Fe, and 0% Pb. Anaerobic biofilter tank with removal efficiency of 4% BOD, 10% COD, -6% TSS, 21% Fe, 0% Pb. Aeration bath with removal efficiency of 56% BOD, 70% COD, 81% TSS, 0.6% Fe, 0% Pb.Settling bath 2 with removal efficiency of 61% BOD, 72% COD, 69% TSS, 33% Fe, 0% Pb. The waste water outlet produced from IPAL Inbis Permata Bunda is in accordance with the quality standards of the Permen LH No. 68 of 2016. Overall the performance of WWTP is still running well but in terms of efficiency, processing time is still too long due to too small discharge. Apart from that, there are still leaks in several processing tanks.
