"Sebagai langkah penanganan meningkatnya pertumbuhan penduduk zona 4 Kota Bogor, PDAM Tirta Pakuan Kota Bogor menerapkan sistem uprating untuk meningkatkan kapasitas debit air olahan menjadi 1000 L/dt yang awalnya 400 L/dt. Sistem uprating juga akan dimanfaatkan untuk meningkatkan kapasitas debit yang direncanakan untuk tahun 2025 berdasarkan proyeksi penduduk dan Pengembangan Optimalisasi PDAM Tirta Pakuan menjadi 1400 L/dt. Penelitian ditujukkan untuk mengevaluasi efektifitas kinerja uprating dan unit instalasi dari segi kualitas dan kuantitas, serta mengetahui kinerja optimum dalam mengolah debit eksisting 1000 L/dt dan debit perencanaan 1400 L/dt. Metode penelitian meliputi observasi langsung di lapangan dan perbandingan data sekunder dan data primer. Dari kegiatan evaluasi diketahui unit uprating dan unit instalasi dapat bekerja optimal dalam mengolah debit 1000 L/dt dari segi kuantitas dan kualitas air produksi. Efektifitas removal instalasi setelah tahun 2005 yaitu sebesar 27,41%, bernilai lebih kecil dibandingkan efektifitas removal tahun 2005 yaitu 55,08%, namun keduanya menunjukkan air minum yang memenuhi standar. Untuk mengolah peningkatan debit 1400 L/dt, beberapa kinerja unit instalasi menurun akibat terbatasnya dimensi unit eksisting, diantaranya unit intake, flokulasi, sedimentasi, reservoar. Dengan demikian, sistem uprating dan unit instalasi WTP Dekeng I perlu dilakukan perbaikan teknis dan perbesaran dimensi pada unit-unit tersebut untuk dapat memenuhi kebutuhan air hingga tahun 2025. ......As the countermeasures of population increase in zone 4 Bogor City, PDAM Tirta Pakuan Bogor applies uprating system to increase the capacity of treated water into 1000 L/s from the foregoing capacity 400 L/s. Uprating system also will be used to increase water capacity which is planned for 2025 based on population projection and Optimization & Development of PDAM Tirta Pakuan to 1400 L/s. This research is purposed to evaluate the performance effectivity of uprating system and installation unit in terms of quality and quantity, also to discover the optimum performance in processing the existing capacity 1000 L/s and planning capacity 1400 L/s. Research methods include the field observation and the comparison between secondary and primary documents. From the evaluation output, known that uprating unit and installation can work optimally in processing water capacity 1000 L/s in terms of quantity and quality water effluent. Removal Effectivity installation in the year after 2005 is 27,41%, which is less than the removal effectiviy in 2005 55,08%; yet both of them produce the drinking water which meets the standard. To process the increase of capacity 1400 L/s, some of performances installation unit decrease due to the limited dimensions of existing units, including units of intake, flocculation, sedimentation, reservoir. Thus, the uprating system and the installation unit WTP Dekeng I needs to be done by technical improvements and dimensional enlargement on the units to be able to comply water demands until the year of 2025"

"ABSTRAKPlaza Great River Indonesia (Plaza GRI) adalah gedung perkantorandengan tipe gedung perkantoran komersial mid-rise yang terletak di kawasan bisnis Kuningan, Jakarta Selatan. Pembatasan konsumsi sumber air yang berasal dari pasokan air tanah dan harga air PDAM yang relatif mahal menjadi penyebabnya melakukan efisiensi air dengan menerapkan teknologi daur ulang limbah cair diproses di lokasi objek penelitian. Hasil analisis kualitas limbah seluler STP yang ada dengan sistem pengolahan Lumpur Aktif tipe Aerasi yang Diperpanjang pada 18 April 2012 di laboratorium diperoleh nilai BOD5 sebesar 39,12 mg/L; COD 75,63 mg/L; TSS 22 mg/L; NH3-N 32,92 mg/L; MBAS 0,11 mg/L; Minyak dan Lemak 1.22 mg/L; dan Fecal Coliform dengan nilai lebih dari 1.600 MPN/100 mL. Skor kualitas efluen telah memenuhi baku mutu pengolahan limbah cair berdasarkan Pergub DKI Jakarta No. 122 Tahun 2005 tentang Pengelolaan Air Limbah Domestik di Provinsi DKI Jakarta, kecuali parameter uji NH3-N. Pemanfaatan air olahan dari proses daur ulang dimaksudkan sebagai pengganti kebutuhan air bersih untuk kegiatan non-potable-urban reuse, meliputi: pembilasan toilet lainnya 66 m3/hari, menara pendingin 48 m3/hari, dan irigasi lanskap 6 m3/hari. Teknologi sistem pemrosesan siklus yang direkomendasikan pengerjaan ulang yang sesuai untuk diterapkan berdasarkan analisis kinerja sistem pengolahan (persentase penyisihan) dan aspek ekonomi (biaya infrastruktur dan operasional /m3) adalah filter karbon aktif (pra-perawatan), osmosis balik, dan Desinfeksi radiasi UV (pasca perawatan), dengan persentase penghapusan total parameter BOD5 94%; COD 95%; TSS 99%; NH3-N 95%;Kekeruhan 96%; dan Fecal Coliform 95% yang mengacu pada pencapaian target kualitas air kelas II berdasarkan PP No. 82 Tahun 2001.ABSTRACTPlaza Great River Indonesia (Plaza GRI) is an office buildingwith a mid-rise commercial office building type located in the Kuningan business district, South Jakarta. Restrictions on consumption of water sources originating from groundwater supplies and the relatively expensive price of PDAM water are the reasons for carrying out water efficiency by applying the technology of recycling liquid waste processed at the location of the object of research. The results of the analysis of the quality of the existing STP cellular waste with an Extended Aeration-type Active Sludge treatment system on April 18, 2012 in the laboratory obtained a BOD5 value of 39.12 mg/L; COD 75.63 mg/L; TSS 22 mg/L; NH3-N 32.92 mg/L; MBAS 0.11 mg/L; Oils and Fats 1.22 mg/L; and Fecal Coliform with a value of more than 1,600 MPN/100 mL. The score of effluent quality has met the quality standard for wastewater treatment based on Pergub DKI Jakarta No. 122 of 2005 concerning Domestic Wastewater Management in DKI Jakarta Province, except for the NH3-N test parameter. The utilization of treated water from the recycling process is intended to replace the need for clean water for non-potable-urban reuse activities, including: flushing other toilets 66 m3/day, cooling towers 48 m3/day, and landscape irrigation 6 m3/day. The recommended rework cycle processing system technology that is suitable to be applied based on the analysis of treatment system performance (percentage removal) and economic aspects (infrastructure and operational costs /m3) is activated carbon filter (pre-treatment), reverse osmosis, and UV radiation disinfection ( post-treatment), with the percentage of total deletion of parameters BOD5 94%; COD 95%; TSS 99%; NH3-N 95%; Turbidity 96%; and 95% Fecal Coliform which refers to the achievement of class II water quality targets based on PP no. 82 of 2001."
