Abstract
This research aimed to examine the relationship between refractive index and light intensity in various fluids. This type of this research was experimental research. The measurement data obtained the refractive index values of various fluids, namely the refractive index of spirit, watered, alcohol, oil, and oil respectively 1. 3066 ± 0. 0053, 1. 319 ± 0. 0056, 1. 3422 ± 0. 0061, 1. 438 ± 0. 0054, 1. 576 ± 0. 0068. The data from the measurement of light intensity in various fluids obtained the valued of the intensity of light that passed through spirit, watered, alcohol, oil, and oil, respectively, namely 1220. 8 ± 3. 72 lux, 1219 ± 3. 9 lux, 1216. 2 ± 3, 77 lux, 1202. 6 ± 3. 88 lux, and 1180. 2 ± 4. 07 lux. The results of this research obtained a valued of r = 1 which indicates that the relationship between the refractive index and light intensity was very strong. The conclusion in this studied was that there was a relationship between refractive index and light intensity. This relationship could been seen in the refractive index, the greater the valued in the fluid would made the transmitted light intensity decrease or inversely proportional.
 Key word: fluid, light intensity, refractive index

Summary
Pada setiap tabel hasil penelitian yakni Tabel 1 sampai Tabel 5 dapat dijelaskan bahwa pada setiap fluida memiliki nilai indeks bias yang berbeda. Pada data nilai intensitas cahaya didapatkan dengan menggunakan alat bantu berupa luxmeter untuk mendapatkan intensitas cahaya awal (I0) dan intensitas cahaya yang dipantulkan (I1). Setelah mendapatkan data tersebut nilai intensitas cahaya yang terbaca pada luxmeter akan dibandingkan dengan nilai intensitas cahaya dari perhitungan matematis. Masing-masing tabel hasil penelitian tersebut juga disajikan dalam bentuk grafik hubungan antara indeks bias fluida (n2) dengan intensitas cahaya yang melewati fluida (I1) sebagaimana yang dapat ditunjukkan dalam Gambar 1 sampai Gambar 5 berikut ini. Berdasarkan hasil yang telah didapatkan maka dapat ditinjau fluida dengan urutan indeks bias terkecil sampai terbesar mengalami penurunan nilai intensitas cahaya yang diteruskan atau ditransmisikan. Pada saat pengukuran intensitas cahaya, sumber cahaya yang digunakan adalah sinar laser berwarna merah
