Abstract

Utilization of The Unmanned Aerial Vehicle (UAV) or Drone has brought revolution in digital photogrammetry. The feature matching on surface reconstruction or Digital Surface Model (DSM) are quickly finished. However, DSM doesn’t represent itself as a part of topography, that is why DSM should be converted into Digital Terrain Model (DTM). This research is to investigate the accuracy of UAV photogrammetry’s DTM  for hydraulic modeling purpose. This study has produced 4 sets of DTMs; 2 sets of DTMs with different grid resolution which are 2 cm & 40 cm, also the 2 other sets of DTM with extra fine nature algorithm and set of filtering parameters adjustment; bulge, offset, spike and standard deviation. Every DTM are validated by Ground Control Point (GCP) from Real Time Kinematic-Different Global Positioning System (RTK-DGPS) measurement. According to the validation, the adjustment of filtering parameters is the most accurate method with Root Mean Square Error (RMSE) of 6,17 cm for 2 cm resolution; and 5,22 cm for 40 cm resolution. Next, DTM UAV is used to estimate the flood water level from Synthetic Aperture Radar (SAR) Image detection with 46 flood images on Glane and Losser area, east part of Overijssel, The Netherlands, since October 2014 to December 2017, then validated with the insitu water level measurement and resulted RMSE 6,72 cm for set of UAV DTM’s 40 cm resolution with the filtering parameters adjustment. Therefore, this DTM UAV can be used as a topography parameter in hydraulic modeling, especially at the similar flat-surface terrain where this research have been conducted.  Keywords: UAV photogrammetry, SAR detection, DTM production

Abstract

Penampungan air hujan (PAH) merupakan salah satu solusi yang dapat diimplementasikan di perkotaan untuk menambah ketersediaan air baku dan mengurangi genangan banjir. Di Indonesia kajian potensi PAH pada wilayah berskala regional masih terbatas sehingga belum memberikan informasi yang cukup bagi penerapan praktis. Penelitian ini bermaksud untuk mendapatkan kurva tampungan PAH sehingga dapat menjadi acuan praktis bagi pengguna dalam memilih volume tampungan sesuai dengan luas bidang tangkap, besarnya kebutuhan air dan reliabilitas yang dikehendaki. Lokasi kajian berada di Provinsi DKI Jakarta dengan 4 wilayah administrasi yaitu Jakarta Timur, Jakarta Pusat, Jakarta Barat dan Jakarta Utara. Kajian ini menggunakan metoda Analisis Simulasi untuk menghitung volume tampungan dengan 4 variasi luasan atap, kebutuhan air dan tingkat reliabilitas. Hasil analisis kurva tampungan menunjukkan semakin besar kebutuhan air dan tingkat reliabilitas yang dikehendaki, semakin besar pula volume tampungan yang dibutuhkan. Di wilayah Jakarta dimana PAH dimanfaatkan sebagai sumber air baku alternatif, dapat dipilih tampungan dengan tingkat reliabilitas 70%. Rumah dengan luas bidang tangkap lebih dari 140 m2 disarankan menggunakan tampungan 2 m3 sedangkan rumah yang lebih kecil dapat menggunakan tampungan 1 m3. Tampungan 2 m3 dapat melayani kebutuhan air maksimal 240 L/rumah/hari sedangkan tampungan 1 m3 dapat melayani maksimal 120 L/rumah/hari.

Abstract

Floods around the Bendung River in Palembang City have caused material and non-material losses. One of the reasons was the decreasing river capacity and backwater during the Musi River flood season, which is the Bendung River's outlet. This paper discusses the impact of adding a pump system to reduce flood impact. 1-dimensional and 2-dimensional numerical model using MIKE 11 and MIKE FLOOD were made to analyze the best measures. Various alternative scenarios were implemented in the model. Based on the modeling results, using the most optimal alternative, alternative 4 with 6 pumps of 36 m3/s and normalization of the Bendung River channel by 1 meter. The inundation area was reduced by 0.74 km2. Also, the maximum inundation height for the flood decreased by 0.6 meters, and the inundation duration was reduced by 8.5 hours. These modeling results can be a reference for managers and policymakers in managing flood events.Keywords: River channel normalization, pump system, numerical model, flood control, Bendung river

Abstract

Rawapening has an area of 2,667 acres, which now ceases to exist. This natural reservoir serves to preserve water, control flood, generate electric turbine, and raw water resource. The depth of this lake decreases 42 cm annually, with the shallowing could cause flooding of the lakeside and and reducing the water supply. This study finds the additional amount of structure and dimension of sabo dam to prevent hazards at each river: at Panjang 2 (B=20m H=2m, and B=25m H=2,5 m), at Galeh 2 (each of B=8m H=2,4m), at Legi 2 (B=10m H=2m, and B=25m and H=2,5m), at Parat 1 (B=13m H=2,7m), at upstream Sraten 1 (B=15m H=2,7m), at downstream Sraten 1 (B=15m H=2,7m), and at Kedungringgis 1 (B=12m H=1,8m). Existing materials are fine and rough sand. Using WaTEM/SEDEM, saboplan guideline by processing the designed capacity, it is estimated that each river’s potential annual yield (in tonnes): Panjang 86.221,8, Galeh/Torong 45.138,24, Legi 42.404,04, Parat 28.579,32, Sraten 25.988,76, and Kedung Ringis 6.955,2. Overall, sabo dam is designed to be a closed type dam located in inlet rivers of Rawapening. Sabo dam construction holds 25% of potential sediment. Collectively, it adds a control volume of 2.885 m3, from 11.539 m3 to become approximately to become 14.424 m3. To cope with sedimentation in Rawapening, the structural approachment (sabodam) should be combined with non structural approachment such as restoring land use in the upstream area for more optimal sedimentation control.Keywords: Sedimentation, rawapening, erosion, WaTEM/SEDEM

Abstract

Batam City is the economic center of Riau Province with a predicted population of 1.8 million people in 2025. To support economic development, Batam City needs a reliable supply of raw water. Mukakuning and Duriangkang reservoirs, which are cascade reservoirs, are the largest contributors to raw water supply in Batam City. This study aims to determine the maximum capacity of the two reservoirs to meet current and future raw water demand. Discharge in the watershed is calculated using daily HEC-HMS model calibrated using Duriangkang Reservoir water level data. The storage of Mukakuning and Duriangkang Reservoir are 6.3 and 106.1 million m3 respectively, equivalent to 39% and 77% of the runoff volume of each watershed, classifying the two reservoirs in the multi-year category. Using current operation, the two reservoirs can supply up to 3.24 m3/s at 100% reliability, compared to existing capacity of 3.1 m3/s. The water loss is dominated by evaporation which reaches 32.6 million m3/year while spilled water is only 8.3 million m3/year. At 95% reliability, the reservoirs are almost at maximum capacity and able to supply 4.03 m3/s of raw water with the spilled water is only 0.4 million m3/year. Efforts to increase capacity by increasing normal water levels are not effective and lead to dam overtopping in PMF condition. More effective way to increase water supply can be obtained by changing operating patterns. If the reservoir is in dry condition, determined by predicted SPI, the water supply is limited so that the discharge can be utilized for a longer period.

Abstract

Degradasi di lahan rawa gambut umumnya diakibatkan oleh alih fungsi lahan dan pemilihan komoditas yang tidak tepat. Alih fungsi lahan yang disertai dengan pembuatan drainase tanpa perencanaan yang matang menyebabkan lahan menjadi kering, mudah terbakar, subsiden, banjir, emisi CO2 dan permasalahan sosial-ekonomi.Penelitian ini dilakukan melalui studi literatur terkait persoalan dan solusi pemulihan lahan gambut terdegradasi melalui restorasi hidrologi dengan metode rewetting (sekat/canal blocking) dan penanaman jenis tanaman yang tidak membutuhkan drainase (paludikultur).Terdapat empat tipe sekat yang biasa digunakan,  yaitu sekat papan, sekat isi, sekat plastik, dan sekat geser. Pemilihan tipe sekat sangat tergantung kepada kondisi bio-fisik, dimensi kanal, topografi gambut, ketersediaan material dan aksesibilitas ke lokasi penabatan. Dari penelitian ini diketahui adanya korelasi yang kuat antara keberadaan sekat terhadap penambahan ketinggian muka air tanah, dimana sekat bermanfaat untuk menaikkan muka air tanah dan melembabkan tanah.Selanjutnya, dalam penerapan paludikultur, diketahui bahwa komoditas tertentu lebih tahan terhadap genangan namun tetap memiliki nilai ekonomi seperti: Metroxylon spp, Nypa fruticans Wurmb, Alseodaphne spp. dan Nothaphoebe spp., dan Shorea spp. Agar dapat bertahan hidup jenis-jenis tanaman tersebut harus dipilih dan disesuaikan dengan ketinggian air yang terdapat di lahan gambut. Kata kunci: Gambut, paludikultur, sekat kanal, restorasi, muka air tanahIn general, degradation on peatlands is mainly caused by excessive conversion and selection of commodities that cannot grow in wet condition. Conversion of peatlands and extreme canalization have become major threats to peatlands which leads to peat fire, subsidence, flooding, green house emission, as well as economic and social problems.This study was obtained from literature study on current problems and solutions of degraded peatlands through peatland hydrology restoration by rewetting method (canal blocking) and cultivation of species that do not require drainage. There are four types of dams that are often used to control water flows, plank dam, composite dam, plastic dam, and sluice. The selection of dam is highly dependent on bio-physical condition, dimensions of canals, peat-topography, availability and accessibility of transportation to the dam site. This research shows that there is strong correlation between canal blocking and the increasing of ground water level, where canal blocking is useful for raising the water table and moisturizing the soil.In the implementation of paludiculture, the certain species / commodities can survive  to wet condition, and also have economic value such as: Metroxylon spp, Nypa fruticans Wurmb, Alseodaphne spp. dan Nothaphoebe spp), dan Shorea spp. In order to survive the type of plants has to be selected and adjusted to the condition of peatlands water level. Keywords : Peatlands, paludikultur, canal blocking, restoration, ground water level
