Abstract
Abstrak. Telah dilakukan perancangan alat ukur tekanan arus air dan analisis laju material dalam air pada sistem aliran sungai dengan metode image processing menggunakan sensor flexiforce. Metode image processing digunakan untuk mengetahui laju material dalam air. Metode pengolahan citra dibuat dengan bantuan perangkat lunak Delphi 7.0 dan dilakukan dengan tiga tahapan pengolahan yaitu, ekualisasi (kontras warna), smoothing dan thresholding. Pada penelitian ini dihasilkan alat ukur tekanan yang bagus ketika digunakan pada range beban 1,31 atm - 9,16 atm dan presentase error tekanan sebesar 5,329%. Uji pengukuran laju material dengan laju aliran air, didapat nilai error pengukuran sebesar 0,08 m/s. Abstract. It has been designed the measure of flow pressure and material system in the river analysis system used image processing method. The designing of this measurement system used to measure the flow pressure and material velocity in the river. This research used flexiforce sensor which have a function to measure the pressure of water flow. Image processing method is used to analysis the material in the water to know the sediment of material velocity. This method was done by 3 step equalization, smoothing and thresholding. Image processing application made by Delphi 7.0. The results in this research, was a pressure measurement system better to use in a range 1,31 atm to 9,16 atm and percentage of error about 5.329% pressure. For measurement of the material velocity, get an error measurement was 0.08 m/s.
