Research on the study of the clay thickness as a parallel plate capacitor dielectric material has been carried out in the Laboratory of Physics, Faculty of Mathematics and Natural Sciences University of PGRI Palembang from May to July 2013. This study aimed to analyze the effect of dielectric material and the the clay thickness to the capacitance of parallel plate capacitor. This research used experimental methods, where clay samples were made of 3 x 5 cm size with a thickness variation of 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 mm. The results obtained showed that the use of clay as a dielectric material increased the capacitance of a parallel plate capacitor. The capacitance values in the thickness of 2, 4, 6, 8, 10, 12, 14,16, 18, and 20 mm were respectively 4.2; 3.2; 3.0; 2.5; 2.2; 2.0; 1.9; 1.8; 1.6; and 1.4 pF for air dielectric material and 128, 118, 115, 105, 98, 92, 89, 74, 67, and 65 pF for clay dielectric material. There was a tendency of the greater thickness of the dielectric material, the smaller the capacitance of a capacitor.Â Keywords: dielectric material, capacitance, clayÂ ABSTRAKÂ Penelitian tentang kajian ketebalan tanah liat sebagai bahan dielektrik kapasitor plat sejajar telah dilakukan di Laboratorium Fisika Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas PGRI Palembang pada bulan Mei sampai Juli 2013.

The purpose of this study was to determine the level of noise caused by vehicles on campus A at PGRI Palembang University. Noise measurements were carried out in 3 different places that were passed by the vehicles of employees and students, namely the parking lot of Building A, Building B and Building C. The study was conducted in October 2020 for 5 working days of data collection. The measurement result data is analyzed by calculating the respective Leq as a measured noise level, then the Leq is compared with the quality standards recommended by the government for noise in educational institutions. The results showed that the noise in the campus A environment of PGRI Palembang University was in the range of Leq 57.3012 - 73.9548 dBA and did not meet the noise level quality standard for educational institutions, namely 55 dBA. This is because the location of the measurement is close to the traffic of vehicles.
