Abstract

Pada penelitian ini telah dianalisis uji keandalan sistem pemanfaatan air hujan dan dirancang sistem pemanenan air hujan pada model green roof yang diterapkan untuk rumah tipe 45 dan 54 di Kota Pontianak agar lebih efektif dan efisien. Berdasarkan hasil analisis sistem pemanfaatan air hujan dengan menggunakan green roof dapat dikatakan handal karena memenuhi kebutuhan primer pada kedua tipe rumah. Sistem pemanfaatan air hujan yang dapat diandalkan untuk memenuhi kebutuhan penghuni rumah tipe 45 adalah 46,5 Liter/Orang/Hari, angka kebutuhan ini dapat digunakan untuk minum, memasak, mandi dan kakus, serta mencuci pakaian. Sistem pemanfaatan air hujan pada rumah tipe 54 dapat diandalkan untuk memenuhi kebutuhan air sebesar 51,5 Liter/Orang/Hari yang meliputi penggunaan air untuk keperluan minum, memasak, mandi, kakus, cuci pakaian, hingga mencuci alat dapur. Hasil perancangan sistem pemanfaatan air hujan adalah sebagai berikut: (1) Dimensi talang air hujan berdiameter 6 inchi yang dipasang di sepanjang kaki atap pada sisi depan dan belakang, kemudian dihubungkan ke tempat penampungan menggunakan pipa vertikal berdiameter 3 inchi. Sistem ini dilengkapi pemisah aliran yang dihubungkan dengan talang vertikal tersebut, sehingga air yang mengandung partikel pencemar dapat dibuang terlebih dahulu sebelum mengisi tangki; (2) Tempat penampungan dapat menampung air 8,2 m3 yang berupa dua buah tangki air polyethylene 4,1 m3; dan (3) Penyangga tempat penampungan terbuat dari kayu berdimensi 4 m x 2 m x 0,95 m. Hasil penelitian diharapkan dapat menjadi solusi komprehensif konsep pembangunan yang ramah lingkungan, relatif murah dan mudah untuk diterapkan serta mampu mengurangi air limpasan (run-off) dengan memperluas area tangkapan air yang menjadi salah satu penyebab permasalahan banjir dan ketersediaan air bersih di Kota Pontianak.

Abstract

Clean water is a fundamental necessity that plays a vital role in supporting various activities within higher education institutions, including Universitas Panca Bhakti (UPB). The availability of clean water that meets quality standards is essential to sustain academic activities, sanitation, laboratory work, and campus facility maintenance. However, the current condition shows that the existing water quality does not comply with the quality standards stipulated in the Indonesian Ministry of Health Regulation No. 2 of 2023. Therefore, a more reliable water treatment system is required. This study aims to design an adaptive and energy-efficient Clean Water Treatment Plant (CWTP) tailored to the characteristics of UPB"™s raw water sources. The methodology comprises three main stages: (1) analysis of raw water quality, (2) technical design of the treatment units, and (3) preparation of the Budget Plan (RAB). The raw water source is derived from rainwater runoff and campus catchment ponds, with an estimated annual potential supply of 88,313 m ³, which is sufficient to meet the campus"™s daily demand of 83.91 m ³. Laboratory tests indicated that the color and Total Coliform parameters exceeded the permitted limits, necessitating a treatment system that includes coagulation-flocculation, horizontal sedimentation, sand filtration, chlorine disinfection, and a clean water reservoir. The system is designed to operate at a capacity of 3.88 L/second, following the technical planning standards set in SNI 6774:2005, considering detention time, horizontal flow velocity, and filtration efficiency. The estimated construction cost for the treatment system is Rp85,900,000. This design is expected to serve as a sustainable and practical solution for clean water management on campus.

Abstract

Clean water access remains a significant challenge in Pontianak City despite high annual rainfall exceeding 3,000 mm. This study aims to design a rainwater harvesting system (RWH) as an alternative source of clean water for the Faculty of Engineering at Universitas Panca Bhakti (UPB). The research employed a mixed-method approach, including field surveys, technical analysis of roof catchment potential, water quality assessment, system design, and financial feasibility using Net Present Value (NPV) and Benefit-Cost Ratio (BCR). The results showed that the building's roof area (571 m ²) with 80% system efficiency could harvest approximately 1,281.32 m ³/year of rainwater, meeting only 18.34% of the building's clean water demand. Due to low pH and nitrate/nitrite contamination, the proposed treatment system includes sand-carbon-zeolite filtration and UV sterilization. Financially, the project resulted in a BCR of 0.76, indicating it is not yet economically viable on its own. However, the system supports UPB's Green Campus 2027 vision by contributing to flood risk reduction, groundwater conservation, and operational efficiency. Future integration with hybrid systems is recommended to enhance sustainability and water resilience on campus.
