Abstract

Ketersediaan air baku masih menjadi salah satu masalah di Kota Balikpapan. Kota Balikpapan yang hanya memiliki waduk dan aliran sungai kecil, harus mencari alternatif-alternatif dalam memenuhi kebutuhan air minum. Pemenuhan kebutuhan air minum pada masyarakat selama ini bergantung pada waduk, aliran sungai kecil dan sumur bor dalam. Namun kualitas air baku yang paling memungkinkan untuk diolah menjadi air minum berasal dari waduk. Sebagian besar waduk yang digunakan bergantung pada musim hujan. IPA Teritip merupakan satu-satunya yang menggunakan sumber air baku dari Waduk Teritip dan baru beroperasi tahun 2019 sebagai pemenuhan penyediaan air minum untuk sebagian besar wilayah Kecamatan Balikpapan Timur. Sehingga untuk mengatasi ketersediaan air baku yang tidak menentu yaitu dengan melakukan daur ulang dari air buangan pada proses pengolahan Instalasi Pengolahan Air (IPA) Teritip.
Perencanaan pengembangan ini menggunakan metode penyesuaian dengan prinsip dan kriteria perencanaan SPAM. Analisis dilakukan secara mendalam pada penggunaan air dalam unit proses, debit air buangan proses dan membandingkan efisiensi pengolahan untuk memaksimalkan air produksi. Sebelum menentukan sistem daur ulang air buangan, dilakukan pengumpulan data primer dan data sekunder. Data primer didapatkan secara langsung pada survey lapangan dan analisis air buangan di laboratorium. Data sekunder dihimpun melalui database PDAM dan penelitian terdahulu. Setelah itu dilakukan pengolahan data dan perencanaan sistem daur ulang berdasarkan kriteria desain dan prinsip pengolahan air minum.
Hasil dari pengolahan data dan perencanaan sistem daur ulang berupa jumlah debit air buangan yang dapat digunakan kembali sebesar 574,67 m3/hari, Detail Engineering Design (DED) yang meliputi perhitungan desain dan gambar detail unit ekualisasi (5,3 m x 5,3 x 2 m), unit sedimentasi (8,8 m x 2,2 m x 3 m) dan Sludge Drying Bed (5,3 m x 2,6 m x 1,5 m) dengan volume Bill of Quantity (BOQ) sejumlah 843 m3, Rencana Anggaran Biaya (RAB) sebesar Rp 405.970.000 dan biaya pengoperasian dan pemeliharaan sistem pengolahan daur ulang air buangan sebesar Rp. 56.834.064/tahun serta analisis kondisi eksisting pengolahan air minum terhadap pengolahan air buangan kembali yang dilakukan pada unit cascade aerator, unit koagulasi dan flokulasi, unit sedimentasi dan unit filtrasi IPA Teritip. Sistem daur ulang air buangan proses ini akan memberi dampak positif dengan menjadikan Waduk Teritip lebih sustain pasokan air baku terhadap musim kemarau.

The availability of raw water is still one of the problems in Balikpapan City. The city of Balikpapan, which only has reservoirs and small rivers, must look for alternatives to meet drinking water needs. The fulfillment of drinking water needs in the community so far depends on reservoirs, small streams and deep bore wells. However, the quality of raw water that is most likely to be processed into drinking water comes from reservoirs. Most of the reservoirs used depend on the rainy season. The erratic trend of changing rainy seasons causes the availability of raw water to be uncertain. IPA Teritip is the only one that uses raw water sources from the Teritip Reservoir and only started operating in 2019 to fulfill drinking water supply for most of the East Balikpapan District. IPA Teritip treatment system managed by PDAM Balikpapan City serves the distribution of drinking water for Teritip Village, Manggar Village, Manggar Baru Village, and Sepinggan Village. So to overcome the uncertainty of the availability of raw water, namely by recycling the waste water in the processing of the Teritip Water Treatment Plant (WTP).
This development plan uses an adjustment method with the principles and criteria of SPAM planning. An in-depth analysis was carried out on the use of water in the process unit, the discharge of the process wastewater and comparing the efficiency of the treatment to maximize the production water. Before determining the waste water recycling system, primary and secondary data were collected. Primary data obtained directly in the field survey and analysis of wastewater in the laboratory. Secondary data were collected through the PDAM database and previous research. After that, data processing and recycling system planning were carried out based on design criteria and drinking water treatment principles.
The result of data processing and planning of the recycling system is the amount of wastewater discharge that can be reused at 574,67 m3/day, Detail Engineering Design (DED) which includes design calculations and detailed drawings of equalization unit (5,3 m x 5,3 m x 2 m), sedimentation unit (8,8 m x 2,2 m x 3 m) and Sludge Drying Bed (5,3 m x 2,6 m x 1,5 m) with Bill of Quantity (BOQ) by 843 m3, the Budget Plan (RAB) of Rp. 405.970.000 and the operating costs and maintenance of waste water recycling treatment system of Rp. 56,834,064/year until the analysis of the existing condition of drinking water treatment on wastewater treatment again which is carried out at the cascade aerator unit, coagulation and flocculation unit, sedimentation unit and filtration unit IPA Teritip. The waste water recycling system of this process will have a positive impact by making the Teritip Reservoir more sustainable in the supply of raw water during the dry season. Another benefit of this process wastewater recycling system is that it reduces the potential for contamination of water bodies and also provides economic benefits.
