Abstract

The reduction of the unit hydrograph from the observed flood hydrograph is an important factor in water construction planning. However, it is difficult to obtain observational flood hydrograph data in the form of AWRL (Automatic Water Level Recorder) and ARR (Automatic Rainfall Recorder) data. Hence, the hydrograph reduction known as synthetic unit hydrograph (SUH) is developed. One of the synthetic hydrographs developed in Indonesia is SUHof ITB-1 and ITB-2. Based on this rationale, this study aimed to analyze the SUH of ITB-1 and ITB-2 in the Bionga Kayubulan sub-watershed. The Straight Line Method was employed to separate the base flow from the run-off in order to obtain a direct run-off hydrograph. In analyzing the effective rain, the study utilized the Φ index equation. Further, the direct run-off and effective rain hydrograph were reduced to the observation unit hydrograph using the Collins method. Additionally, Microsoft Excel-Solver software was used to optimize the SUH of ITB-1 and ITB-2 coefficients on the hydrograph of the observation unit. The hydrograph of the observation unit in the Bionga Kayubulan sub-watershed attained 4.5 hours peak time (Tp) with 2.81 /s peak discharge (Qp). The ITB-1 synthetic hydrograph in the site area attained 5.97 hours peak time (Tp) with 1.96 /s peak discharge (Qp), while the ITB-2 synthetic hydrograph attained 5.97 hours peak time (Tp) with 2.45 /s peak discharge (Qp). The calibration results of ITB-1 synthetic unit hydrograph with changed coefficient parameters showed the time coefficient (Ct) of 0.73, the peak coefficient (Cp) of 1.07, and alpha (α) of 1.60. Further, for the SUH of ITB-2, the results showed a time coefficient (Ct) of 0.73, a peak coefficient (Cp) of 0.96, alpha (α) of 2.50, and beta (β) of 0.95.

Abstract

Limited water resources in coastal areas is a problem often encountered, with high rainfall intensity being one of the most potent factors to solve it. Pelehu Village is one of regions located in Gorontalo District, a coastal area that was experiencing said problem. Rain intensity is one of the parameters used in calculating the discharge, in wich a proper analysis method based on Bubaa Drainage Basin at Paguayamn Pantai is necessary. The quality of the rainwater that will be used should also be qualified by the water characteristics based on the quality standards, in wich water samples to test the parameters of Chemistry, Physic, and Bacteriology are required. Rainwater harvesting installation system also requires planning and budget planning; therefore, this research aimed to analyze rainwater potential, water characteristics, and rainwater harvesting installation budget plan in Pelehu Village. The inhabitants’ needs for water were calculated based on the projected population growth from 2021 to 2025. Rainfall intesity was analyzed uaing Normal, Log-Normal, Log Pearson III, and Gumbel distributions, while the method used to analyze the rainfall intensity was Mononobe. The rainfall data were retrieved from Bubaa Drainage Basin at Paguyaman Beach for the last seven years. The tested characteristics of rainwater are mandatory Physical, mandatory Chemical, and Bacteriology parmeters based on the quality standard im Permenkes No. 32 of 2017. Budget plan was calculated based on the planning of rainwater harvesting instalation in Pelehu Village Office. The analysis of population growth from 2021 to 2025 is 833, 853, 874, 895, and 917 people, with 66.624, 68.247, 71.611, 73.355 liters/day of water needs amount. The value of Cv, Cs, and Ck of rainfall intensity analysis result of the statistical parameters were 0,84, 3, and 0,2, respectively; hence, the most compatible distribution pattern was the Log Pearson III. The highest precipitation intensity occured in five minutes for return periods of 100 years, wich was 197,75 mm/h. Water discharge was calculated with the rational method of 0,8420 m3/ sec ≈ 824,027 liters/sec. The rainwater potential in the village is 2966,4975 m3/h ≈ 2.966.498 liters/hour. The rainwater characteristics have met the quality standards for the parameters of Chemistry, Physics, and Bacteriology based of Permenkes No. 32, 2017.

Abstract

Karakteristik penggunaan lahan dan tanah merupakan sifat-sifat fisik DAS yang mempunyai pengaruh dalam menentukan aliran, yang dinyatakan dalam suatu indeks berupa Curve Number (CN). Sungai Sogitia yang terletak di Desa Sogitia, Kecamatan Bone, Kabupaten Bone Bolango, Provinsi Gorontalo memiliki sumber air yang dapat mecukupi kebutuhan air baku di sekitaran Desa Sogitia. DAS Sogitia memiliki luas DAS 15, 39 km², dengan panjang sungai utama 4,69 km. Proses terbentuknya aliran air sungai (debit) sebagai fungsi parameter komponen sistem DAS dan input presipitasi hujan dapat dinalisis melalui suatu teknik pemodelan hidrologi menggunakan Model HEC-HMS. Nilai Curve Number ditentukan dengan melihat peta tata guna lahan dan peta jenis tanah, serta time lag dihitung menggunakan Persamaan Kirpich. Berdasarkan hasil Penelitian kondisi penggunaan lahan di DAS Sogitia didominasi oleh hutan dengan luas 7,73 km², serta jenis tanah yaitu mediteran merah kuning yang termasuk dalam jenis tanah alfisol dengan tekstur lempung pasir berliat. Parameter yang didapat berupa Curve Number (CN = 69,31), Initial abration (Ia = 22,49 mm), dan Time Lag (TL = 9 menit). Hasil dari pemodelan HEC-HMS pada DAS Sogitia tahun 2009 sampai 2019 dengan debit puncak terjadi pada 21 Mei 2014 dengan nilai besaran debit 30,2 m³/s. Perhitungan debit andalan sungai untuk memperoleh nilai debit yang terpenuhi sepanjang waktu dilakukan dengan menggunakan metode flow duration curve (FDC). Keperluan irigasi dibutuhkan probabilitas 80% dengan nilai 1,3 m³/s. Lokasi penelitian tidak terdapat daerah irigasi, sehingga probabilitas 80% tidak digunakan. Untuk keperluan air baku dan industri debit andalan untuk probabilitas 90% yaitu sebesar 1,1 m³/s.

Abstract

The primary problem in a region with limited water resources is the use of irrigation water and this limited water resource is associated with water volume losses in the irrigation channel, particularly in the primary, secondary, and tertiary channels through evapotranspiration, infiltration, and seepage. Therefore, the irrigation channel reguires effective and efficient management. The objective of this study is to evaluate the efficiency of Lomaya Irrigation Area to denote water use and to maximize the water use for agriculture. This study is conducted by applying field data in the primary channel of Lomaya Irrigation Area and data from the climatology of Bolango Bone Tumbihe Watershed. The data collected are a wet cross-sectional area of channel and flow speed in several vertical points. The average daily evaporation rate and water losses in the primary channel of Lomaya Irrigation Area are determined by employing Penman evaporation method. In addition, the efficiency value is obtained by comparing inflow and outflow debit in the irrigation channel. The result of water losses value analysis in the Lodelombongo irrigation channel due to evaporation is 5,14 m³/sec, and the value is not too influential for the water losses in the channel compared to the water losses due to leakage in the channel. In the meantime, the average efficiency value in the Lodelombongo irrigation channel is 61%, where it is no longer in compliance with the predetermined provision in the irrigation planning criteria. The greatest efficiency value in primary channel BLI-BL2 is 92,42%, whereas the smallest value in the primary channel BL3-BL.BI is 49,35Y%, the greatest efficiency value in secondary channel BL.B3-BL.B4 is 72,64%, whereas the smallest value in the secondary channel BL.BS-BL.B6 is 43,89%. The efficiency value is affected by water volume, which losses on its way where the water losses in the irrigation channel encompass water losses components through evapotranspiration, percolation, seepage, and leakage.

Abstract

The location and number of rain stations in a watershed area are the main components in ensuring the availability of rainfall data. Evaluation of the rain station network density is needed to determine the condition of the distribution of rain stations and new rain stations recommendation. The research was conducted in the Bolango Bone watershed with 10 existing rain stations. Rainfall observation data in 7 years (2013-2019). The location and number of rain stations were analyzed using the Kagan-Rodda method based on the standards set by the WMO (World Meteorological Organization) of 100-250 km2/station. The result of the Kagan Method is the optimal number and pattern of placement of rain stations. The evaluation results from 10 stations in the Bolango Bone watershed showed that there were 3 stations, namely Pangi, Pinogu, and Sukamakmur, which did not meet the density of rain stations suggested by WMO. The correlation coefficient for monthly rainfall ranged from 0.4238-0.8351. This correlation value was the average of all rain stations in the Bolango Bone watershed. Based on the results of the Kagan-Rodda analysis, two recommendations were obtained. The first recommendation is to maintain the existing 10 stations with an average error Z1 = 4.12%, interpolation error Z2 = 9.24%, and the distance between stations l = 14.58 km, repositioning the rain stations to each vertex of the Kagan-Rodda triangle. The second recommendation is to add 4 new rain stations without repositioning the existing 10 rain stations with an average error Z1 = 3.45%, interpolation error Z2 = 8.93%, and distance between stations l = 12.32 km.
