1 SISTEM DRAINASE BERWAWASAN LINGKUNGAN (EKO-DRAINASE) UNTUK MENDUKUNG SANITASI
Oleh: Ir. Isri Ronald Mangangka, M.Eng., Ph.D (Dosen tetap pada Fakultas Teknik Unsrat) This template can be used as a starter file for presenting training materials in a group setting. Sections Right-click on a slide to add sections. Sections can help to organize your slides or facilitate collaboration between multiple authors. Notes Use the Notes section for delivery notes or to provide additional details for the audience. View these notes in Presentation View during your presentation. Keep in mind the font size (important for accessibility, visibility, videotaping, and online production) Coordinated colors Pay particular attention to the graphs, charts, and text boxes. Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale. Graphics, tables, and graphs Keep it simple: If possible, use consistent, non-distracting styles and colors. Label all graphs and tables.

2 SISTEM DRAINASE SISTEM DRAINASE ADALAH SUATU SISTEM
YANG BERTUJUAN UNTUK MENGALIRKAN AIR HUJAN DAN LIMPASAN PERMUKAAN This is another option for an Overview slides using transitions.

3 DRAINASE KONVENSIONAL
FILOSOFI DRAINASE KONVENSIONAL EKO-DRAINASE Air hujan dan limpasan permukaan merupakan ancaman yang dapat menimbulkan banjir dan genangan Air hujan dan limpasan permukaan serta jalan air/saluran alami adalah aset yang dapat dimanfaatkan untuk berbagai tujuan (reuse, estetika, etc.)

4 DRAINASE KONVENSIONAL
KONSEP DRAINASE KONVENSIONAL EKO-DRAINASE Air hujan dan limpasan permukaan secepat-cepatnya dibuang ke badan air terdekat agar tidak menimbulkan banjir/genangan. Upaya penanganan air hujan dan limpasan permukaan secara komprehensif dengan metoda detensi, retensi dan infiltrasi

5 DRAINASE KONVENSIONAL
PENDEKATAN/ APPROACH DRAINASE KONVENSIONAL EKO-DRAINASE Mitigasi banjir Mitigasi dampak hidrologi dan dampak lingkungan

6 DRAINASE KONVENSIONAL
TUJUAN/OBJECTIVE DRAINASE KONVENSIONAL EKO-DRAINASE Hanya fokus pada penanganan kuantitas air hujan. Multi objectives: - Kuantitas - Kualitas - Landscape & Estetika - Amenity - Konservasi - Restorasi ekologi - Etc. This is another option for an Overview slides using transitions.

7 DRAINASE KONVENSIONAL
KEUNTUNGAN & KERUGIAN DRAINASE KONVENSIONAL EKO-DRAINASE Bersifat destruktif: Meningkatkan banjir di hilir Kekeringan di hulu Penurunan cadangan air tanah Ancaman bagi ekologi perairan Benefit: Air hujan diolah untuk dimanfaatkan kembali Pengisian kembali air tanah Meningkatkan kualitas ekologi dll.

8 DRAINASE KONVENSIONAL VERSUS EKO-DRAINASE
Tujuan dari Drainase Konvensional fokus pada penanganan banjir/kuantitas air hujan tapi Penanganan kuantitas air hujan Oleh Eko-Drainase jauh lebih baik

9 KUANTITAS AIR HUJAN DAN METODA DRAINASE

10 IMPLEMENTASI EKO-DRAINASE
DI AMERIKA SERIKAT – SUSTAINABLE URBAN DRAINAGES SYSTEM (SUDS) DI AUSTRALIA – WATER SENSITIVE URBAN DESIGN (WSUD) DI INDONESIA – MENGALAMI KENDALA

11 KENDALA IMPLEMENTASI EKO-DRAINASE DI INDONESIA
Limbah Dapur Limbah WC/KM Air Hujan Limbah Cucian Air Limbah Lain-lain Stormwater System Sewerage System Drainase Tercampur Kondisi Ideal

12 DUKUNGAN IMPLEMENTASI EKO-DRAINASE DI INDONESIA
PERATURAN PEMERINTAH NO. 42 TAHUN 2008 TENTANG PENGELOLAAN SUMBER DAYA AIR: JARINGAN DRAINASE HARUS TERPISAH DENGAN PENGUMPUL AIR LIMBAH PERMEN PEKERJAAN UMUM NO.12/PRT/M/2014 TENTANG PENYELENGGARAAN SISTEM DRAINASE PERKOTAAN: REKOMENDASI MEMBANGUN SISTEM DRAINASE RAMAH LINGKUNGAN

13 LEBIH JAUH TENTANG EKO-DRAINASE
METODA EKO-DRAINASE: DETENTION SYSTEM RETENTION SYSTEM INFILTRATION SYSTEM MULTI OBJECTIVES: KUANTITAS KUALITAS ESTETIKA DLL. This is another option for an Overview slides using transitions.

14 SISTEM DETENSI Detention Tank (Reservoar Detensi)
Detention Pond (Kolam Detensi) Water quality treatment through settling (pengendapan) Including particle-bound polutant: Phosphorus, heavy metal & hydrocarbon In Out In Out

15 SISTEM RETENSI Kolam Retensi In Out Infiltrasi

16 SISTEM RETENSI Kolam Retensi Danau Buatan Water quality treatment
through settling, Biochemical processes (nitrification and denitrification). Landscape aesthetic, water supply

17 SISTEM RETENSI Filter Strip Water quality treatment
through settling, filtration (penyaringan), vegetation uptake. Landscape aesthetic, sport facility

18 Water quality treatment = Filter strip
SISTEM RETENSI Grass Swale Water quality treatment = Filter strip

19 Water quality treatment = Grass swale Filtration through filter media
SISTEM RETENSI Bioretention Swale Water quality treatment = Grass swale + Filtration through filter media

20 SISTEM RETENSI Rawa buatan (Constructed Wetland)
Water quality treatment through settling, adsorption, vegetation uptake , biochemical decomposition. Landscape aesthetic, water supply

21 SISTEM RETENSI Bioretention Basin
Water quality treatment through filtration (penyaringan), vegetation uptake.

22 SISTEM INFILTRASI Sumur Resapan (Soakwell) Rainwater disposal
Groundwater recharge

23 SISTEM INFILTRASI Infiltration Trench

24 SISTEM INFILTRASI Porous Pavement Rainwater disposal
Groundwater recharge

25 SISTEM INFILTRASI Modular Pavement Rainwater disposal
Groundwater recharge
