Abstract

Solar radiation data is useful for solar power plant (PLTS) development, the agricultural sector, renewable energy, transportation and communication, and other disciplines. This data is generally obtained from government agencies. The device used to measure solar radiation is a pyranometer. However, this equipment has limited availability and the data information is only owned by certain regions. Therefore, it is necessary to develop a simpler measuring instrument for the intensity of solar radiation. So that data information is obtained easily and the operation of tools is easy. In this study, photovoltaic panels were used to read the intensity of solar radiation. When this panel is exposed to the sun it will generate electricity and its output is proportional to its radiation. Data monitoring utilizes IoT. The measured results of measuring the intensity of solar radiation have a maximum value of 450.21 W/m2. The measured magnitude of the solar radiation value shows that the influence factors in the form of sunlight intensity, ambient temperature, and panel output power are proportional to the radiation value while environmental humidity is inversely proportional to the radiation value.

Abstract

Metal residues in the soil at shallow depths can be detected with simple detectors. Development was carried out using several equipment tests. The purpose of this research is to design a simple metal detection system by testing the coil diameter, the wire diameter, and the number of coil windings to determine their effect on the detection distance of the metal detection system. The metal detection system in this study uses the pulse induction method, which uses one coil as a transmitter and receiver. The wire used 4 types of diameter sizes. For one size of wire diameter, three variations of the number of coil windings are made, and for each variation of the number of coil windings, five variations of coil diameter are made. The test results show that the diameter of the coil affects the detection distance of a simple metal detection system, the larger the diameter of the coil, the farther the detection distance for medium and large-sized metals, while for small metals, the lower the detection distance. Wire diameter affects the detection distance of a simple metal detection system, the larger the wire diameter, the farther the detection distance, and vice versa, the smaller the wire diameter, the lower the detection distance. The number of coil windings affects the detection distance of a simple metal detection system, the more turns, the farther the detection distance, while the fewer turns, the closer the detection distance.
