ABSTRAKTelah dilakukan penelitian pemanfaatan interferometer Michelson untuk menentukan kualitas madu bunga. Uji kemurnianÂ dilakukan berdasarkan pengukuran konstanta Kerr madu yang diperoleh dengan mengukur indeks bias bahan menggunakanÂ interferometer Michelson. Nilai konstanta Kerr Rk berbeda untuk kandungan gula pereduksi (glukosa dan fruktosa) yangÂ berbeda dari bahan (madu). Diketahui bahwa semakin besar kandungan gula pereduksi maka semakin besar nilai konstantaÂ Kerr. Nilai Rk yang besar menandakan molekul polar pada konsentrasi madu bunga tersebut lebih mendominasi dari padaÂ molekul nonpolar, dan sebaliknya untuk nilai Rk yang kecil. Pada penelitian ini menggunakan sampel madu bunga kaliandra,Â kelengkeng, kapuk dan rambutan. Rk yang besar diperoleh pada madu bunga kaliandra pada konsentrasi 10% sebesarÂ (1,33Â±0,02) Ã10-12 m2/V2 dan nilai Rk yang kecil diperoleh madu bunga kelengkeng pada konsentrasi 20% sebesar Â (3,04Â±0,07)Ã10-13 m2/V2. Semakin besar konsentrasi madu yang diberikan pada media sampel maka semakin besar nilai Rk.Â Ini disebabkan karena meningkatnya konsentrasi akan menghasilkan komposisi madu lebih banyak dari konsentrasiÂ sebelumnya, sehingga secara fisis akan meningkatkan kerapatan bahan sehingga indeks bias bahan semakin besar karenaÂ molekul madu dalam sampel semakin banyak. Pengukuran konstanta Kerr dilakukan dengan memberikan variasi medan listrikÂ pada sampel madu uji untuk melihat perubahan jumlah frinji interferensi.Kata kunci: efek Kerr, kemurnian bahan, gula pereduksi, interferometer Michelson, konstanta Kerr

Parallel plate capacitor is widely used as a sensor for many purposes. Researches which have used parallel plate capacitor were investigation of dielectric properties of soil in various temperature [1], characterization if cement’s dielectric [2], and measuring the dielectric constant of material in various thickness [3]. In the investigation the changing of dielectric constant, indirect method can be applied to get the dielectric constant number by measuring the voltage of input and output of the utilized circuit [4]. Oscilloscope is able to measure the voltage value although the common tool for that measurement is voltmeter. This research aims to investigate the accuracy of voltage measurement by using oscilloscope and voltmeter which leads to the accuracy of values of dielectric constant. The experiment is carried out by an electric circuit consisting of ceramic capacitor and sensor of parallel plate capacitor, function generator as a current source, oscilloscope, and voltmeters. Sensor of parallel plate capacitor is filled up with cooking oil in various concentrations, and the output voltage of the circuit is measured by using oscilloscope and also voltmeter as well. The resulted voltage values are then applied to the equation to get dielectric constant values. Finally the plot is made for dielectric constant values along the changing of cooking oil concentration. The results show that the plot of dielectric constant values which are gained from the voltage measurement using voltmeter have better linearity compare to the other plot in which the voltage measurement utilize the oscilloscope. In conclusion, voltmeter is considered better equipment to measure a voltage compare to the oscilloscope in term of getting dielectric constant values of parallel plate capacitance sensor.

Cement is an adhesive material that is capable of tying dense ingredients into one solid unity, cement was used as construction materials. Any materials including cement has physical properties and is largely determined by the magnitude of the internal condition of the materials. This research was conducted to find out the quality of cement by using measurements of the dielectric constant and resistivity values. The materials examined in the form of 3 brands of cement mixed with sand and water. This research method using capacitive and resistive by using an oscilloscope as a voltage reader. Note that the three cement brands have the same dielectric constant value i.e. amounting to 0.30 and resistivity value of 30.00 Ωm on day 28. The relationship between the dielectric constant value against the addition of age showed a decrease, while for values of resistivity shows an improvement. Onthe measurement of the dielectric constant shows that cement A brand more quickly achieve drying compared to brand B and brand C, as for the measurements of the resistivity shows that cement brand C more quickl yachieve drying compared to cement brand A and brand B.

Fat is a food substance that is very important to maintain the health of the human body. One source of fat is animal fat. Differences in the type of fat can be known based on the electrical properties of materials such as dielectric constant and capacitance. The purpose of this research is to know the characteristic of dielectric constant and capacitance in animal fat by giving treatment of temperature and frequency variation. This research uses parallel plate capacitor method which is connected to the source of alternating current input voltage and voltmeter as the output voltage meter. The samples studied were chicken fat and beef fat. This research uses input voltage with frequency of 1kHz up to 20kHz, while temperature that is used is varied from 45⁰C decrease to 30⁰C. The results obtained from this study show that the increasing frequency results to the decreasing values of capacitance and dielectric constant in chicken fat and cow fat. The effect of temperature on the capacitance and dielectric constant of chicken fat and cow fat shows non linear relationship
