Abstract

Wilayah terluas sebagai penghasil beras di Pulau Jawa adalah Kabupaten Indramayu. Sebagian besar Kabupaten Indramayu berada di daerah pesisir, airtanah menjadi sumberdaya yang sangat dibutuhkan untuk irigasi pertanian. Eksploitasi yang berlangsung secara terus menerus dan volum yang semakin meningkat dari waktu ke waktu menyebabkan terbentuknya ruang kosong di lapisan akuifer sehingga ruang kosong pada tanah kemudian diisi oleh air laut. Pada penelitian ini Jaringan Saraf Tiruan (JST) digunakan untuk memprediksi intrusi air. Tujuan penelitian untuk menentukan peta zonasi intrusi berdasarkan kualitas airtanah, yaitu total dissolved solid (TDS) ,dan daya hantar listrik (DHL). Penelitian dilakukan di 33 kecamatan dengan 83 titik sampling pada bulan Februari 2017. Luas sawah di Kabupaten Indramayu sekitar 57,94%, dengan kontur berupa dataran rendah dengan daerah endapan di timur laut. Pasokan air permukaan Kabupaten Indramayu berasal dari DAS Cimanuk, Cipunegara, dan Cipanas. Pada musim kemarau air tanah Kabupaten Indramayu sudah dieksploitasi berlebihan untuk sumur bor sebagai irigasi. Akuifer bebas terletak 3 - 30 meter di bawah permukaan tanah, dengan tebal sekitar 15 - 20 meter, mengalir dari selatan ke utara. Topografi Kabupaten Indramayu berada pada ketinggian 0 - 100 meter di atas permukaan air laut dengan kemiringan rata-rata 0 - 2%. Hal inilah yang menyebabkan Kabupaten Indramayu tergenang air saat curah hujan tinggi. Nilai kualitas airtanah didapat bahwa bagian utara dan timur lebih besar dari selatan dikarenakan batas pantai terletak di bagian utara dan timur.Keywords: EC, Indramayu District, intrusion, TDS

Abstract

The approach to calculating evaporation and evapotranspiration, both potential and actual, varies widely. The models used to estimate the amount of evapotranspiration, particularly at the Maros Climatology Station, Maros Regency, South Sulawesi. Evaporation models use the Penman, Priestley, Bruin, and Valiantzas models while evapotranspiration models use the Penman, Hargreaves, Jensen-Haise, Penman-Monteith, Radiation, Turc, and Makkink models, where all of these methods use climate data, such as are the minimum temperature (Tn), maximum temperature (Tx), air temperature (Ta), average humidity (RH), rainfall (R), duration of sun exposure (SS), and maximum wind speed (U) in calculations using Visual basic program in Microsoft Excel in the form of code. Thus, it is necessary to conduct an analysis of the suitability of the model to the results of the observations in order to find out which model is suitable according to the results of the largest coefficient of determination (R2). Based on the results of the model suitability analysis, a selected model was obtained, namely the Valiantzas model with a value of 0.980 in the evaporation calculation and the Jensen-Haise model, namely 0.889.

Abstract

A review of air temperature in the Palembang city by reviewing data from the National Agency for Meteorology, Climatology, and Geophysics/BMKG (Kenten Climatology Station and the SMB II Meteorological Station) shows a difference in air temperature can indicate the occurrence of Urban Heat Island (UHI). The difference in air temperature affects the evapotranspiration rate (ET) because air temperature very influencing water evaporation. ET rate estimation with air temperature data is the first step to prove this hypothesis. Hargreaves and Samani, Blaney and Criddle, Linacre, and Kharuffa models is the ET model that using air temperature as the variable was used to estimate the ET rate. Air temperature data used in the period 2011-2020 by reviewing data from the Kenten Climatology Station and the SMB II Meteorological Station. The results of this study of air temperature data from the Kenten Climatology Station and the SMB II Meteorology Station showed a difference in air temperature with the minimum ∆T of 0.42 oC, the maximum of 0.43 oC, and the daily average of 0.41 oC. This difference in air temperature has an impact on the difference in the ET rate with the average ∆ET of the Hargreaves and Samani model of 0.05 mm/day, the Blaney and Criddle model of 0.05 mm/day, the Linacre model of 0.06 mm/day, and the Kharuffa model of 0.14 mm/day. The results of this study predicted that an increase in air temperature causes an increase in the ET rate of ± 10-30%.
