Superposition of waves experiment in physics subject need more innovation to dig up student knowledge about the essential of waves in physics. Such innovation is using Audacity software for analyze it. The purpose of this study is to analyze the superposition of sound waves using Audacity software in the wave superposition experiment. The method used is to prepare tools and materials, namely PC/laptop, 250 Hz, 1 kHz audio files and Audacity Software. Then, 250 Hz and 1 kHz audio is sampled in one wave using Audacity after which each audio sample is imported twice and then combined with Audacity software and saved. This is done for different audio frequencies as well. Then, the results of the merger are opened with Audacity and then analyzed and compared with the initial wave. And the resulting superposition of two 250 Hz waves produces an amplitude of twice and 250 Hz and 1 KHz is produced over a 4 ms wave period and the constructive and destructive wave amplitudes depend on the phase of the two waves. Thus, wave superposition experiments using Audacity software facilitate the analysis of superposition results and characterize the period and amplitude properties of waves.

An antenna radiation pattern experiment has been carried out with the aim of determining the patch antenna radiation pattern on a logarithmic and linear scale, understanding the properties and principles of the antenna, and understanding the types of antenna radiation patterns. In the experiment, the angle, frequency, and radian intensity data were obtained, and the value of the linear intensity was calculated. With the principle of converting electrical signals into electromagnetic signals. a graph between angle and intensity is obtained. the graph between radian intensity and angle forms a circular pattern, in which the value of intensity and frequency at each point with a difference of 5 degrees has almost the same value. In conclusion, the antenna is a structure that can receive and release electromagnetic waves in the air. The patch antenna used has a unidirectional radiation pattern. Converts electromagnetic signals into electrical signals and vice versa, has a certain radiation pattern, and is easily disturbed by metallic materials.

The learning model used so far is still less effective, which is one of the reasons for the low learning outcomes of mathematics in students. This study aims to analyze the needs of the learning model on students' mathematics learning outcomes. This research is a qualitative research with qualitative description research type. The research subjects were students of class VIII Junior High School. The research data were collected by means of interviews and observations. The results of this study indicate that: (1) the teacher has not been precise in choosing the learning model (2) students have not been actively involved in learning in class (3) students still do not dare to ask if they have difficulties so that the learning process is not effective (4) students in the teaching and learning process only listen, take notes, do what the teacher tells them to do and do not dare to ask for difficulties in understanding the material. Therefore, it is necessary to decide the right learning model in the teaching and learning process of mathematics in order to make it easier for students to accept the material presented.

This research is a pendulum experimental study in determining the acceleration of Earth's gravity and understanding the concept of simple harmonic motion. This research was conducted at the Physics Laboratory of the University of Muhammadiyah Lamongan. This study aims to examine the benefits of conducting pendulum experiments with the simple pendulum swing method and in determining the acceleration of Earth's gravity, the period of oscillation and concepts in simple harmonic motion with variations in the mass of the pendulum, namely 150 grams, 75 grams and 35 grams. The results of the analysis of this study obtained the acceleration of Earth's gravity 9.79 m/s where the mass and length of the pendulum do not affect the value of gravity. While in simple harmonic motion in the form of pendulum oscillation is influenced by the length of the string. The pendulum oscillation will experience energy dissipation in maintaining its equilibrium position due to the gravity of the earth.

Teaching facilities used by students so far have not provided initiative in the learning process. This study aims to analyze the need for teaching materials according to the problem based learning (PPL) method. This research is a qualitative research with descriptive qualitative research type. The research subjects were class VII junior high school students. Research data was collected through interviews and observation. The results of the study show that: (1) All curriculum contents are in accordance with KI, KD (2) Teachers and students do not understand the contents of the curriculum (3) Teachers and students are interested in teaching materials in the PBL Approach (4) Teachers and students need to learn with the PBL PBLroach because it makes students actively participate in the learning process in class. Therefore, teaching materials with a PBL PBLroach are needed.

Research on the Characterization of the Light Dependent Resistor (LDR) Light Sensor has been carried out with the aim of understanding the characteristics of the LDR light sensor, for processing changes in the LDR resistance value as a measurement of light intensity and for accessing an 8-bit resolution ADC by entering the LDR light sensor voltage result. The value of the resistance on the LDR depends on the size of the light received by the LDR itself. In addition, the greater the intensity of light hitting the LDR surface, the smaller the resistivity. On the other hand, the smaller the intensity of light hitting the LDR, the greater the resistance value. The basic principle used in the use of LDR resistors as components of this sensor is the change in the resistance value and the amount of current flowing in the circuit. In this experiment, the distance variations of 0cm, 3cm, 6cm, 9cm, 12cm, 15cm, 18cm, 21cm, 24cm, 27cm and 30cm were used. LDR characteristics are slow response in identifying light intensity, the greater the light intensity the smaller the resistivity, LDR can be used to read changes in light intensity and data retrieval can be done with an op-amp and a microcontroller.
