Development of Teaching Materials Algebraic Equation to Improve Problem Solving

Problem-solving skills are the basic capabilities of a person in solving a problem and that involve critical thinking, logical, and systematic. To solve a problem one-way necessary measures to solve the problem. Polya is one way to solve a mathematical problem. by developing teaching materials designed using the steps in solving problems Polya expected students could improve its ability to solve problems. In this first year, the goal of this study is to investigate the process of learning the hypothetical development of teaching materials. This study is a research & development. Procedure development research refers to research the development of Thiagarajan, Semmel & Semmel ie 4-D. Model development in the first year is define, design, and development. The collection of data for the assessment of teaching materials algebra equations conducted by the expert by filling the validation sheet. Having examined the materials of algebraic equations in the subject of numerical methods, reviewing the curriculum that is aligned with KKNI, and formulates learning outcomes that formed the conceptual teaching material on the material algebraic equations. From the results of expert assessment team found that the average ratings of teaching materials in general algebraic equation of 4.38 with a very good category. The limited test needs to be done to see effectiveness teaching materials on problem-solving skills in students who are taking courses numerical method

Beberapa Permasalahan Dalam Penganggaran Modal

In capital budgeting processes, there are some crucial problem related to infation and the criteria in making the decision. Among the two discounting methods, analysts may use NPV or IRR. If NPV is used in making capital investment decision, some still doubt that project having zero NPV is still a good project. In this paper we try to explore how important infation factor to be considered in capital badgeting. The fnancial professional literatures dealing with investment decisions, state in general that the net present value shows objective picture for the decision maker. The net present value shows the amount of wealth growth that have been accumulated by the investment during the life time of the project, but the investment’s internal rate of return informs the decision maker that how works the real yield of long capital investment. The NPV method is theoritically superior to the IRR method in dealing with mutually exclusive project. The Project having zero NPV is considered to be proftable. In general terms, a sound capital investment will earn its original investment and cover the cost of capital invested. In the countres with high rate of infation, the efect on capital investment can be dramatic, so that cash fow adjustment is very critical

Pengaruh Perbedaan Rasio Work Interval Dan Rest Interval Terhadap Kecepatan Lari

The aim of this research is to know (1) the difference in effect between interval anaerobic training with working time ratio and the time off 1 : 5 and 1 : 10 on the achievement of 100 m sprint. (2) Interval anaerobic training its give better influence with working time ratio and the time off 1 : 5 and 1 : 10 on the achievement of 100 m sprint.The research used experiment method with macthed by subjects design. The research population is the male students of Madrasah Aliyah Al Mukmin Ngruki Sukoharjo. The variable research consist of two independent variable i.e. interval anaerobic training with the ratio of 1:5 and 1:10, and one dependent variable is 100 m sprint achievement. The technique of gathering data used test technique and measurement. The data of 100 m sprint achievement was taken by doing running test as for as 100 m. Data analysis technique is done by analysis t, on significant grade of 5%. The conclusion of the research : (1) There is a significant difference in effect between interval anaerobic training with the ratio of 1 : 10 and 1 : 5 toward the achievement of 100 m sprint. (2) Interval anaerobic training with working time ratio and the time 1 : 10 give better influence to be compared to ratio 1 : 5 the achievement of 100 m sprint
