Abstract

Telah dilakukan penelitian tentang penentuan dan analisis nilai resistivitas thin film dengan identifikasi ukuran sampel menggunakan metode image processing. Penelitian ini berupa perancangan, pengembangan, percobaan, dan analisis data percobaan. Analisis data percobaan dilakukan untuk melihat tingkat akurasi pada alat ini. Sampel yang diukur adalah thin film berbahan dasar Nikel Kobalt. Dari hasil percobaan, didapatkan bahwa alat ini bekerja dengan baik, walaupun digunakan untuk pengukuran sampel ukuran kecil. Alat juga memberikan data resistivitas yang akurat, dengan deviasi data yang kecil dibandingkan dengan data pengukuran secara manual. Pola yang dihasilkan dari hasil pengukuran alat ini dapat memberikan kesimpulan tentang pengaruh resistivitas terhadap variasi komposisi bahan dasar thin film.

Abstract

Total Dissolved Solids (TDS) and turbidity of water are parameters to determine the quality of water. In this research, instruments development and study of accuracy level for TDS meter and turbidimeter have been made. Instruments were made using TDS sensor and turbidity sensor that were inexpensive and available on the market. The samples used for instruments examination were water with dye (Rhodamine B) and powder of coffee as impurities. The results showed that the sensors worked properly and provided a better accuracy in measuring water samples with coffee impurities than dye impurities. The inaccuracy on the determination of water samples with dye impurities due to dye particles which have soluble properties on water and microscopic size than particles of coffee.
