Abstract

Mathematically, in calculating oscillations and waves, it can be used using analytical and numerical techniques. For simple movements, numerical techniques are easier to perform than analytical techniques. Because, apart from the difficulty of using analytical techniques, the calculations carried out are also complex. The actual value of a wave or oscillation can be determined using analytical techniques, while numerical techniques are simply calculations carried out close to the analytical value. The aim of this paper is to analyze analytical and numerical techniques in wave and oscillation analysis. The type of research used in this research is based on qualitative research. The results obtained in determining trigonometric integrals require a calculation that can use analytical and numerical techniques. Numerical techniques are calculations that are almost correct or close to the value. However, to get the actual value correctly, analytical calculations are needed. Analytical calculations are quite difficult to do, but need to be done to serve as a reference. The conclusion drawn is that in trigonometric integrals in wave and oscillation analysis, numerical calculation techniques and analytical techniques can be used. When using numerical techniques, you can use formulas , whereas calculations using analytical techniques can use formulas.

Abstract

Improving the quality of Human Resources (HR) is a major challenge in facing global competition. Education as the main means of improving the quality of HR in Indonesia is still faced with the problem of inequality of access and quality between regions. This inequality causes disparities in educational development between urban and remote areas. This study focuses on grouping provinces in Indonesia based on aspects of educational development in 2023, using cluster analysis. Secondary data from the Central Statistics Agency (BPS) is used as the basis for analysis, including variables of average length of schooling, Gross Participation Rate (APK), Pure Participation Rate (APM), number of senior high schools, and community literacy development index. This study uses hierarchical and non-hierarchical cluster analysis methods to group provinces in Indonesia. The results of the hierarchical cluster analysis using the average linkage method show the most optimal cluster with the formation of three clusters. The first cluster consists of 31 provinces, the second cluster consists of 2 provinces, and the third cluster consists of 1 province. Data characteristics show large variations in the number of senior high schools and relative homogeneity in the average length of schooling between provinces.

Abstract

Surfaces in three-dimensional space can be represented through explicit, parametric and implicit equations, which describe the relationship between the variables x, y and z. Graphs of linear equations produce flat planes, while quadratic equations form objects such as spheres or ellipsoids. In this research, a theoretical approach is combined with interactive visualization to analyze various surface shapes. Through the use of GeoGebra software, this analysis makes it easier to understand surface orientation and shape, such as normal vectors and curvature, as well as applications in vector fields. This research also investigates the concepts of Cartesian coordinates in three-dimensional space, by depicting surfaces in the form of graphs of functions of two variables. It is hoped that the results of this research can provide deeper insight into the geometric properties of surfaces and how to visualize them effectively in mathematics and physics applications.
