Abstract

The inundation area is an area that inundated by water in case of the drainage channel cannot accommodate the flow of discharge, which causes the material losses and disturb the community activities. However, to solve the problem of flooding in Pekanbaru can not be done thoroughly because of the limited funds. Therefore, it is necessary to prepare the priority scale of channel rehabilitation drainage in Pekanbaru. The preparation of priority scale of drainage channel is done by using Analytic Network Process (ANP) method and assisted with Super Decisions software. The preparation of the priority scale refers to the rules minister of public works number: 12 / PRT / M / 2014. The results show there are 10 locations which ranked by the priority scale from the highest to the lowest which is the highest priority is the Tanjung Datuk street of Limapuluh subdistrict and the lowest is kota baru street of Senapelan subdistrict.Keywords : Analytic Network Process, Inundation, Drainage channel, Priority scale

Abstract

Waterwheel comprises of giant wheel equipped with bamboo buckets which rotates due to water flow to lift water from the river to the higher elevation paddy field. The waterwheel model usedin this research was the undershoot water waterwheel. The waterwheel has 55 cm of diameter, 18 blades (6 cm-long and 6 cm-wide), and 1764 kg of weight. This research was done by varying the number and dimension of the boxes to obtain the waterwheel’s optimal number of boxes. The number of boxes variation was 6, 12, 18, 24, 30, and 36 boxes. The box quantity variation was 6.67 ml, 10.5 ml, and 16 ml. The water flow rate was not varied. The result of this research shows that the rotation rate of the waterwheel was affected by the velocity of water driving theblades. The number and volume of the boxes affect the rotation rate of the waterwheel. The maximum flow rate that could be lifted by the boxes was 474.44 ml/minute, 647.78 ml/minute,and 1083.33 ml/minute for type 1, 2, and 3 boxes, respectively.Keywords: model, waterwheel, undershoot

Abstract

Rangsang Island is described as a peat island located on the east coast of Riau Province. Due to the high conversion of peatlands, the peat of Rangsang Island is degraded and continuously emits emissions. Efforts to restore degraded peatlands are implementing good water management. In assessing the condition of the peatland water system, this study will analyze the water balance in the Peat Hydrological Unit (PHU) of Rangsang Island to determine the condition and quantity of water contained in the peatland. The model used in peatland water balance modeling is the Thornthwaite & Mather Water Balance (TMWB model). The analysis and discussion will examine the condition of the peatland water balance in the Rangsang Island PHU which is calculated using the land water balance method. From the results of this study, the condition of the water balance of the peatlands in Sub PHU 3, Rangsang Island, is dominantly experiencing deficit months. The deficit months occurred in January, February, March, May, July, August, October and December. The total water deficit is -104.20 M3. While the wet months occur in April, June, September and November. The total surplus of water is 26.15 million m3. The total water deficit for a year when compared to the total surplus of water for a year there is still a big enough difference so that a good and sustainable water-compliant system is needed on peatland Sub PHU 3 Rangsang Island, especially in the Rangsang Island KHG in general in the future.Keywords: Deficit, Peat Hydrological Unit, Peat land, Surplus, Thornthwaite & Mather Water Balance

Abstract

More than 40% of Padang Island area has been concessioned by the Ministry of Forestry to PT. RAPP. The construction of large-scale canalization of peatland utilization adopted by the company’s concessions causes disruption of the water balance. Research at Peat Hydrological Unit (PHU) Padang Island isnecessary so that peatland protection and restoration become more efficient and effective. The method used in this study is Thornthwaite Mather Water Balance (TMWB). Water balance depicted in a temporal graph showing the deficit/surplus status in every month and Geographic Information System (GIS) used for spatialdata analysis at PHU Padang Island. The results of land water balance analysis in PHU at 2020, shows that the highest drought (deficit) level was in the Sub-PHU 1 on February with the 26.83 million m3. For the highest wetness (surplus) level was in the Sub-PHU 1 on November with 31.34 million m3.Keywords : deficit, Peat Hydrological Unit, surplus, Thornthwaite Mather Water Balance, water balance.

Abstract

This study examines variations in the initial time of observation based on the Hijri calendar which aims to determine the most accurate time to make observations in the field. The analysis of this research used the Admiralty method with hourly observation data for 15 days. The data uses tide data in Kotabaru waters and simulated against two hundred and forty-three time variations. The results of the data analysis show that the smallest average root mean square error (RMSE) resulting from the 15-day tide prediction is 16.68 cm, which is the prediction of the start date of the 16 Hijri calendar. So that the most appropriate time to make tidal observations in the field for tidal predictions in Kotabaru waters is on the 16th of each Hijri month or during the fourth moon phase (humpback month). The value of the formzhal number obtained is 0.66, so the tidal type in the study location is included in the semi-diurnal tide type classification.Key words: beginning time, admiralty method, RMSE.

Abstract

Peramalan pasut dapat menggunakan beberapa metode analisis, yaitu Admiralty, Least Square dan Spectrum. Penelitian sebelumnya hanya melakukan verifikasi menggunakan data pengamatan dan tidak memperhatikan tanggal dalam pengambilan datanya, karena waktu pengambilan data akan mempengaruhi nilai komponen-komponen pasut yang akan dihasilkan. Penelitian ini menggunakan metode Admiralty, karena menghasilkan tingkat kesalahan rata-rata yang lebih kecil dan dapat menggunakan data pengamatan pasut dalam jangka waktu pendek. Data pengamatan selama 15 hari dengan pengamatan tiap jam, disimulasi terhadap tiga puluh lima variasi waktu pengambilan awal data pengamatan menggunakan penanggalan Hijriah. Hasil yang diperoleh pada lokasi penelitian di Apra Harbor, Guam, Mariana Islands ini menunjukkan bahwa nilai RMSE terkecil terdapat pada variasi awal data pengamatan di sekitar tanggal 24 sampai 08 siklus bulan berikutnya pada penanggalan Hijriah, yaitu saat terjadi fase bulan sabit akhir sampai fase bulan cembung awal. Tipe pasut menunjukkan nilai F pada lokasi ini masuk pada klasifikasi tipe pasut campuran condong harian ganda (mixed tide prevailing semidiurnal), tetapi untuk setiap siklus bulan terdapat simulasi yang nilai F nya masuk pada klasifikasi tipe pasut campuran condong harian tunggal (mixed tide prevailing diurnal) yaitu dominan terjadi pada variasi data pengamatan tanggal 10 sampai 24 penanggalan Hijriah.Kata Kunci : Hijriah, Metode Admiralty, pasang surut, RMSE
