Abstract
Efforts to monitor the fertility of waters from nutrients that have harmful effects on the activities of creatures have been developed. The manufacture of ion selective electrodes as a nitrate detection sensor is one of them. However, in reality the tools and materials as well as the high enough price to obtain them are necessary. Graphite pencils are thought to be able to replace carbon glass in the polypyrrole coating Cycle and use Arabic Gum as an emulsifier for the manufacture of nitrate sensors. The research was conducted using potentiometric methods, selectivity tests and validation tests for sensor performance. The results of this study prove that the graphite pencil nitrate sensor works well in the optimal treatment of 0.5 M polypyrrole coating with the addition of 0.5% Arabic Gum in a variation of 13 Cycles. The sensor being tested was also able to check the nitrate content without being purchased by ion intruders as indicated by the validation test results that were not significantly different from the UV-Vis spectrophotometer. Keywords: Arabic Gum, Nitrate Sensor, Graphite Pencil, Polypyrrole, Potentiometry Upaya monitoring kesuburan perairan dari zat hara yang berpotensi menimbulkan dampak berbahaya bagi aktivitas makhluk hidup telah banyak dikembangkan. Pembuatan Elektroda Selektif Ion sebagai sensor pendeteksi nitrat salah satunya. Akan tetapi ketersediaan alat dan bahan serta harga yang cukup tinggi untuk memperolehnya perlu dipertimbangkan. Grafit pensil diduga mampu untuk mengganti carbon glass pada siklus pelapisan polypyrrole serta menggunakan Arabic Gum sebagai pengemulsi untuk pembuatan sensor nitrat. Penelitian dilakukan dengan metode potensiometri, uji selektivitas dan uji validasi untuk mengetahui performa sensor. Hasil penelitian ini membuktikan bahwa sensor nitrat berbahan grafit pensil bekerja dengan baik pada perlakuan optimum pelapisan polypyrrole 0,5 M dengan penambahan Arabic Gum 0,5%, dalam variasi 13 Cycle. Sensor yang diuji juga mampu mendeteksi kandungan nitrat tanpa terpengaruh oleh ion pengganggu ditunjukkan dengan hasil uji validasi yang tidak berbeda signifikan dengan spektrofotometer UV-Vis. Kata kunci : Arabic Gum, Sensor Nitrat, Grafit pensil, Polypyrrole, Potensiometri
