Abstract

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.

Abstract

The purpose of this study was to determine the effect of adding variations in substrate concentration and the effect of variations in the surface area of the electrodes (anode and cathode) on the power density, resulting in a maximum power density value for a period of 13 days. measurement. The first step is measuring voltage and current with substrate concentration without dilution process, then variation of concentration is carried out with 10 times, 8 times, 5 times, 4 times, and 2 times dilutions on ceramics with a diameter of 8 cm. . The second step is to measure the voltage and current by varying the surface area of the electrodes (cathode and anode). The measurement results showed that the maximum power density value obtained was 188.23 mW/m2 without a dilution process, namely with a concentration of 3640 ppm for the 3rd day. While the results of the measurement of the variation of the electrode surface area obtained a maximum power density value of 205.88 mW/m2 on the electrode surface area of 3.57 m2 for the third day. The more surface area of the electrode given at the time of measurement, the more bacteria that are in contact with the electrode, causing the value of the resulting power density to be greater.Keywords: waste tofu, microbial fuel cell (MFC), power density, electrode, ceramic

Abstract

The yard can provide great benefits for the community, because it can be planted with vegetables, fruits and spices such as turmeric, lemongrass, etc. The yard can also be used as a source of animal protein and an additional source of family income. Quail farming is an alternative for producing eggs which is quite productive in addition to laying hens and ducks. The advantages of quail cultivation are having a small body size and weighing about 130 grams, a short life cycle, high egg productivity (in the peak period of daily egg production it can produce about 90% of the total population in the cage), low feed intake (about 20 grams/quail/day), easy to cultivate and does not require a high investment. Quail can give results in the form of daily egg production and/or meat from rejected quail (quail that have stopped laying eggs or egg productivity that begins to decline after about 8 months of age). Quail cultivation from the yard of the house can be used to maintain approximately 25 quails. Based on these advantages, quail cultivation in the yard can provide family income and increase nutrition. Keywords: quail, yard, nutritional, income
