Abstract

This research aims to analyze the characteristics of superposition waves in the musical instrument known as "saron" in the gamelan ensemble. In this study, three types of gamelan sarons were used as research instruments: "saron demung," "saron barung," and "saron panerus" or "peking." The sounds produced by these musical instruments were recorded, mixed, and analyzed using Audacity software and Spectra Plus Sound Card Edition. The analysis results conducted with Audacity and Spectra Plus Sound Card Edition revealed the presence of superposition waves that either reinforced each other when they had the same phase and frequency or weakened each other when they had different phases and frequencies. Therefore, this study concludes that audio mixing that falls under constructive or reinforcing superposition of waves is the combination of "saron demung" with "saron demung." On the other hand, audio mixing that falls under the destructive superposition of waves includes the varieties of "saron barung" with "peking," "saron barung 1" with "demung," "saron barung 2" with "peking," and "saron barung 2" with "demung."

Abstract

The process of learning physics can be in the form of conducting a research or experiment so that the results will become a new understanding concept contained therein. The use of the experimental method is intended to be able to observe directly various kinds of phenomena that occur in physics. The purpose of this study is to observe the difference in sound from each glass filled with water with a different volume, to analyze the frequency and period, and to describe the phenomena that occur in experiments with the help of ''frequency counter'' software. This experiment was carried out by filling three glasses with water of different volumes and hitting one side of the glass using a weight attached to a support with a rope. Simultaneously operate the ''frequency counter'' software to determine the difference in frequency of each glass. The research results obtained, the three glasses produce sounds that have different frequencies and periods, namely for the first glass (1758.21 Hz); (0.73672 m/s), second glass (2158.35 Hz); (0.45727 m/s), third glass (2170.69 Hz); (0.39740 m/s). Also, the phenomenon that occurs is diffraction (bending).

Abstract

This research was aimed to determine the distribution pattern of magnetic field anomaly and to identify the lithology of underground structure in Bribin Karst using geomagnetic method. Research location was Semanu Sub-district, Gunungkidul Regency at UTM coordinate of 464061 mT-464929 mT and 9111097 mU-9111970 mU. The data were taken using G-5 Proton Precession Magnetometer (PPM) by looping method. The result showed that the distribution pattern of the magnetic field anomaly in Karst Bribin has value of 330 nT - 530 nT and anomaly values reflecting the system of Bribin River has value of 400 nT-460 nT. The lithology of underground structure in Karst Bribin has susceptibility value of -0.069 (in SI) - 0.0661 (in SI) with depth 200 m associated with limestone, tuff, gypsum, rock salt, and minerals calcite and anhydrite and the lithology associated with the system of Bribin River has susceptibility value -0.069 (in SI) associated with gypsum, rock salt, and minerals anhydrite.
