This article describes format of a curve of cable when they are free hanging under gravity, held on two tips at same elevation. The curve is known as a catenary. Description was developed started by analysis of forces equilibrium working on the cable lasting on getting general solution, and the

This study aims to analyze the types of investment that should receive highest priority in improving achievement of human development in Indonesia. To answer these research goals, this is used the simultaneous equations models analysis for panel data of 30 provinces in Indonesia with involving education level, income level, health

Rhodamine B is a synthetic color that use for textile. It is prohibited to be used in foods as it is hazardous to health. Recently, it is being used to make ground red chili and other foods more colorful and brighter. A study was carried out at tradisional market in

This paper examines batch scheduling problem that have batching and sequencing in single formulation. The first step is to develop a model for single item single resource model discussed in Halim et al. (1998) has determined batch sizes and the schedule for the resulting batch sizes in two steps, but

Pixel Value Differencing (PVD) represents one of the algorithms in steganography. This algorithm was found in the year 2001 where some were developed and others were repaired. Based on algorithm of PVD, the main purpose was to obtain the difference between two nearby pixels which were used to count message

The research discusses a method to solve ordinary differential equations of second order at regular singular points by power series. The method for solving ordinary differential equations at ordinary points by power series does not apply in this case. The first method is usually more complicated than the second

A period function of real variable x can perform Fourier Series which initially was used in heat equation solution in the form of partial differential equation. Harmonic analysis can be used to find coefisien an and bn from Fourier Series on functions of data sets transferred to particular interval which

Statistics is a science that has important role in decision making. The decision is made based on the data and uses certain methods, especially statistical methods. Error in choosing a test in statistical methods can result in an incorrect decision. Statistical methods are divided into two parts, parametric statistical method
