Abstract

describes the pattern of relationship between internet usages on students, on the assessment of aspects of selfregulated learning. The aspect of self-regulated learning measured from 10 aspects. This study discusses the effects ofgender, the categories of schools (excellent schools and regular school), the total value of self-regulated learning andthe value of math exams. In brief, the research stages consist of three stages. The first stage of research is to createand retrieve the questionnaire data. The goal is to obtain all things related to internet usage, as well as measure aspectsof self-regulated learning assessment. The second stage of treatment on students. This treatment time is done for fourmonths, where students follow the math lesson with self-regulated learning method. Students provided with multimediadevices, textbooks and other. The third stage is the assessment or math test. The analytical method used is qualitativemethod with descriptive statistical approach. The results obtained that the dominant male students using internet forgames tend to have greater Aspects of Finding and Utilizing Relevant Learning Resources. While female, tend to bedominant in aspects of Evaluating Learning Processes and Results. The average mathematical exam results, in studentswho often use the game tend to have a higher value, compared with other students who often use social media.

Abstract

an expression of conflict in the field. To overcome this problem is a regulation of several parameters,including regulation of planting schedules and reduction of land area. The model of the irrigation water managementsystem used is based on the risk of land failure and the optimum area of land that can be planted. The parameters usedto overcome this problem are planting schedules, risk of land failure and factor k. The k factor is the ratio of wateravailability to water needs. The output of this system is optimal net benefit based on the optimal alternative irrigatedland area. The results of the formula will show the optimal amount of land area that produces optimal net benefitsbased on certain planting schedules and certain effective rainfall. This system will also show that optimization will beachieved if there is a water balance between the availability and needs of irrigation water. The system referred to inthis study is a dynamic system. The purpose of this study is to make a preliminary design of a dynamic system to optimizethe irrigation system of agricultural land. The results obtained in this study were in the form of feedback loops andinteractions between loops with each other in agricultural irrigation systems.
