Abstract

Daerah aliran sungai Siak bagian hilir merupakan kawasann gambut yang luas dengan kategori gambut sangat dalam (lebih dari 4 meter). Hingga Agutus 2017, berdasarkan laporan Jaringan Kerja Penyelamat Hutan Riau (Jikalahari) jumlah hotspot pada lahan gambut di Provinsi Riau dengan kedalaman lebih dari 4 meter mencapai 397 titik. Kebakaran hutan dan lahan gambut merupakan agenda tahunan Riau, khususnya pada musim kemarau (kering). Tingkat kekeringan suatu daerah dapat diketahui dengan menghitung indeks kekeringannya. Indeks kekeringan merupakan suatu perangkat utama guna mendeteksi, memantau dan mengevaluasi kejadian kekeringan. Salah satu metode guna menghitung indeks kekeringan adalah metode Thornthwaite Mather. Metode tersebut menekankan pentingnya faktor curah hujan dan evapotranspirasi potensial. Analisis kekeringan dilakukan berdasarkan data hujan yang terukur dan tercatat pada 4 stasiun di dalam daerah aliran sungai Siak meliputi Buatan, Kandis, Petapahan Baru dan Pekanbaru. Hasil analisis menunjukan nilai total maksimum indeks kekeringan terjadi pada tahun 2014 dan Tahun 2015 dengan persentase sebagai berikut stasiun hujan Buatan 466,31%, Kandis 398,33%, Petapahan Baru 757,17% dan Pekanbaru 520,77%.

Abstract

Siak river basin now in criticial condition. This condition is due to land use changes in the upper body and cause silting in the river. The silting decreasing the capacity of the river so when heavy rain occurs, tha rivers could not accomodate it and it will cause flooding. The flood disaster which is very difficult to predict and lack of water resources at dry season made the citizens lack of preparation to deal with. A solution to anticipate that is to provide an early warning system. In order for the system to work well, it need a prediction method that could provide good quality of data, the method called SOM-ANN. SOM-ANN method consisted by two different types of algorithms, there are Self Organizing Maps (SOM) and Backpropagation. The purpose of this study was to test the reliability of SOM-ANN method in discharge predicting in Tapung Kanan River. The weighting result from SOM’s learning applied to Backpropagation’s learning, so that the pattern recognizing becomes faster and gaining more accuracy. By a comparison with ANN method, SOM-ANN method can improve a better performance and accuracy of predicting results with 1099% increase in performance and 44,74% increase in accuracy with an error value MSE = 0,001725, so that the discharge prediction modelling can be used to predict the discharge in the future.Keywords : artificial neural network, self organizing maps, discharge, prediction modelling

Abstract

Rainwater harvesting that is good and right by the needs of household clean water is one of the problems for the people in the islands in Indonesia, especially Merbau Island which is located in the Kepulauan Meranti Regency, Riau Province. The only source of clean water that can be enjoyed easily and cheaply is rainwater. Rainfall on Merbau Island ranges between 2.000 ? 4.000 mm per year which is classified as moderate. A survey of 100 randomly selected people was conducted, with a questionnaire containing components for rainwater harvesting (RWH) and other core questions. If available rainfall is used optimally, the need for clean water on the island can be met. Calculation of rainwater for cooking, drinking and washing needs is estimated to be around 15 lpcd. The data obtained is rainfall in 2016 with a total rainfall of 1,754 mm, roof storage area of 36 m2, and the type of roof used is zinc. Rain cycle V2 simulation produces a 3 m3 volume rainwater storage tank, with a construction cost of Rp. 10,365,000. This tank can meet the needs of clean water for five family members for a year.
