Abstract

The purpose of this study is to describe the mistakes of class VII A students at SMP Negeri 2 Genteng, Banyuwangi Regency. This type of research uses descriptive qualitative. This type of research uses descriptive qualitative. Data collection techniques used written tests and semi-structured interviews. The subject of this research was class VII A students located at Genteng 2 Public Middle School. Subject data obtained 3 types of errors based on castor theory including conceptual errors, procedural errors, and technical errors. Conceptual errors include not writing formulas and symbols, writing formulas and symbols incorrectly. Procedural errors include, not writing down known, asked, or conclusions, wrongly writing down information known to the problem, unclear writing down the information asked, wrongly writing down the steps for solving the problem, not writing down the solution step at all. Technical errors include, not writing units in numbers that have units or answers, not writing units in the final answer, wrong writing units in numbers that should have units or answers, wrong writing units in the final answer, and wrong doing arithmetic operations

Abstract

This research was motivated by the problem of learning mathematics in simple fractions. The approach is a qualitative approach with the type of research being classroom action research. The data in this research is based on test results, observations and interview results. The data source in this research was class III UPTD students at SD Negeri 4 Peusangan, totaling 17 students with various levels of ability. Based on the research results, it was found that the SAVI approach was used for class III students at UPTD SD Negeri 4 Peusangan on simple fraction material. This is proven by the increase in the number of students who completed their learning in the initial test, namely from 47% belonging to the poor category before learning took place, in cycle I it increased to 65% belonging to the sufficient category and in cycle II it increased to 88% belonging to the good category. Meanwhile, the results of observations on the activities of teachers and students of class III UPTD SD Negeri 4 Peusangan on simple fractions material have increased with the percentage of teacher activity in cycle I, namely 85% belonging to the good category.

Abstract

This research aims to develop a bilingual mathematics module for KSM in the field of integrated mathematics. The research method uses the Research and Development (RnD) method of the Borg and Gall model which is simplified in 4 stages, namely introduction, development, testing and dissemination. The results of the development of a bilingual (Indonesian-Arabic) mathematics module at KSM are suitable for use. The validation results from media experts have an average value of 3.69 and are in the suitable category for use. Media expert validation has an average value of 3.70 and is in the category suitable for use. The validation results by practitioners have an average value of 3.62 and are in the suitable category for use. Trials by subject teachers had an average score of 3.71 and were in the very interesting category. The individual trials had an average score of 3.61 and were in the very interesting category. Small group trials in each madrasah had an average score of 3.83 and were in the very interesting category and large group trials had an average score of 3.74 and were in the very interesting category. The final stage is dissemination carried out by distributing bilingual mathematics module books.

Abstract

In this paper discussed about ship heading control problem. Ship heading control is one of the ship control problem in the application in the marine field. With rudder angle as input control, the heading angle controlled therefore it can reach reference heading angle with minimum energy. Assume that is wave disturbance to the system. We compare two method for control the heading angle, that is Proportional Integral Derivative (PID) and Model Predictive Control (MPC). Proportional Integral Derivative (PID) is a controller that determine the presition of an instrumentation system with feedback characteristic on the system. MPC is a control technique, which embeds optimization within feedback to deal with systems subject to constraints on inputs and states. From the simulation result, MPC can compansate the disturbance better than PID. The time to reach reference angle when controlled using MPC faster than using PID. The change value of Np also almost give same result. But the change parameter PID can give very difference result seen from the rise time, the settling time, and the overshoot.
