Abstract

Abstrak Hidroponik adalah metode penanaman tanaman tanpa menggunakan tanah, yang menggunakan media air sebagai pengganti. Dalam penanaman hidroponik, pengukuran pH (tingkat keasaman) dan TDS (Total Dissolved Solids atau jumlah padatan terlarut) dalam larutan nutrisi sangat penting untuk memonitor kondisi lingkungan pertumbuhan tanaman. Kedua sensor ini terlebih dahulu dikalibrasi dan dikarakterisasi untuk mengetahui fungsi kerja dan tingkat korelasinya. Kalibrasi sensor pH dan TDS dilakukan dengan menggunakan larutan standar dengan tingkat pH dan TDS yang diketahui, serta alat ukur berupa pH Meter dan TDS Meter sebagai pembanding standarnya. Data kalibrasi digunakan untuk mengoreksi hasil pengukuran sensor dan memastikan akurasi yang tinggi. Selanjutnya, dilakukan karakterisasi sensor pH dan TDS dengan menguji responnya terhadap variasi konsentrasi larutan nutrisi. Hasil karakterisasi digunakan untuk memahami kinerja sensor dalam mengukur pH dan TDS dalam berbagai kondisi. Didapatkan persamaan kalibrasi untuk sensor TDS yaitu y=2.6345x-414.72 dengan korelasi sebesar 0.9265 sedangkan untuk sensor pH memiliki persamaan y= 0.0169x+0.2745 dengan korelasi sebesar 0.9311. Kata-kata kunci: Sensor, pH, TDS, kalibrasi. Abstract Hydroponics is a method of growing plants without using soil, which uses water as a substitute medium. In hydroponic planting, measuring pH (acidity level) and TDS (Total Dissolved Solids or the amount of dissolved solids) in a nutrient solution is very important to monitor environmental conditions for plant growth. These two sensors are first calibrated and characterized to determine their work function and degree of correlation. Calibration of pH and TDS sensors is carried out using standard solutions with known pH and TDS levels, as well as measuring instruments in the form of pH meters and TDS meters as standard comparisons. Calibration data is used to correct sensor measurement results and ensure high accuracy. Next, the characterization of the pH and TDS sensors was carried out by examining their response to variations in the concentration of nutrient solutions. The characterization results are used to understand the performance of the sensor in measuring pH and TDS under various conditions. The calibration equation for the TDS sensor is y=2.6345x-414.72 with a correlation of 0.9265 while for the pH sensor it has the equation y= 0.0169x+0.2745 with a correlation of 0.9311. Keywords: Sensor, pH, TDS, calibration.
