Abstract

creating a school atmosphere orderly and discipline is very important. Therefore is necessary to a regulation rules which would regulate the behavior patterns of students in the school. But with a growing pattern of student behavior, violation of school rules are common, especially in SMK Yuppentek 1 Tangerang. As a teacher in charge of providing services and counseling to students, it is the responsibility of counseling teachers to provide guidance to students with problems. Not many schools are aware of the importance of the use of information and communication technologies so that the process of recording and calculating the value of point offense, coaching up sanctions against students who violate the order was carried out with conventional systems. This resulted in the BK teachers takes a long time to handle students who have problems of having to create some bookkeeping records violation and fill the violation book manually so that the handling results are often invalid. In addition, delivery of information about good and bad behavior of students in the school to parents or guardians of students experiencing difficulties. In order to help the BK teacher performance, it needs to be made a system to calculate the point value rules violation at SMK YUPPENTEK 1 Tangerang. By using the methodology of research in the form of a SWOT analysis, it is expected that the system can simplify and accelerate the process of calculation of point offense, coaching until the sanctions to students who violate rules, and the delivery of information to parents or guardians of the student's behavior will be faster.In addition, principals can also find charts the level of discipline students based on grade level and department.

Abstract

In analysis of time series, variance error always be assumed constant. Nevertheless, there are some financial economic data such as exchange rate data that variance error has not constant. This research describes an alternative model in analysis of time series which allowed variance error as an autoregressive process that recognized by GARCH (Generalized Autoregressive Conditional Heteroscedastic). GARCH model was used for modeling time series with residual condition variation according to the time. Estimated of parameter GARCH model can be used with MLE (Maximum Likelihood Estimation) method. At the end of this thesis is represented the variance model of exchange value of Rupiah (IDR) to American Dollar (USD). This research was based on daily data from January 2002 to December 2005. The result of the research show that rate of exchange value IDR to USD satisfied the assumption from GARCH model and GARCH (2,2) model is the most appropriate for  the time series data.

Abstract

Converter tegangan BCD ke Desimal 0-3 V adalah sebuah rangkaian elektronika dengan menggunakan mikroprosessor yang dirancang untuk dapat mengubah besaran tegangan BCD menjadi besaran tegangan 0-3 V. Pada Gardu Induk (GI) 150 KV atupun Gardu Induk Tegangan Extra Tinggi (GITET) 500 kV terdapat berbagai macam bay yang diantaranya adalah Bay Line, Bay Trafo, dan Bay Kopel. Khusus pada bay trafo, terkadang salah satu status yang belum terakuisisi dan termonitor pada RCC adalah status posisi tap changer. Pemilihan tap trafo secara otomatis dilakukan dengan suatu peralatan relai AVR. Relai AVR, relai pengatur tegangan adalah peralatan kontrol otomatis pada transformator yang menggerakan motor OLTC. Namun, pada saat tap trafo telah melebihi nilai maksimumnya maka dapat menyebabkan AVR blok. Dengan adanya kondisi seperti ini maka tentunya dapat menyebabkan suatu penyimpangan tegangan yang cukup besar. Tindakan pencegahan yang dilakukan untuk mengatasi AVR blok adalah dengan memonitoring posisi tap pada trafo. Oleh karena itu, dalam penelitian ini dibuat suatu converter sederhana berbasis mikroprosessor untuk mengubah format input tegangan BCD menjadi tegangan 0-3 V.

Abstract

This research aims to: (1) obtain a valid mathematics learning tools model cooperative script with realistic mathematics approaches to improve mathematics communication skills; (2) a practical mathematics learning tools model cooperative script with realistic mathematics approaches to improve mathematics communication skills; (3) test the effectiveness of mathematics learning tools model cooperative script with realistic mathematics approaches to improve mathematics communication skills; The research consisted of two stages. The first stage is developing a learning device. The second stage is the implementation of learning using the learning device. The development of learning tolls in this study adapting development model proposed by Thiaragajan, Semmel, & Semmel includes define, design, develop, and disseminate. Disseminate not implemented in this study. The average value of the validation by the experts that developed the device is good. Individual mastery test results showed t calculate  7.3420296 > t table so it can exceed Minimum Criteria of Mastery Learning. Average test results the classical completeness showed z calculate  2,4495 is outside the reception area of H₀. So, it can be concluded mathematics learning model of cooperative script with realistic mathematical approaches to effectively help student achieve complete Minimum Criteria of Mastery Learning. The result test difference in average value of mathematical communication ability test showed t calculate  6.277818 > t table. This means that the average student mathematical communication ability test experimental class is better than the average test communication ability mathematical student control class. Being two different test results show the proportion of z calculate  2.30551 is outside the reception area H₀. So it can be concluded that the number of students with communication skills math test scores reached the limit of Minimum Criteria of Mastery Learning in the experimental class more than the number of students who reach the limit value Minimum Criteria of Mastery Learning completed in experimental class. Data were analyzed by SPSS 17 resulted in the regression equation Y ̂ = 51.652 + 6.019X₁ + 5.562X₂, It means each additional character variable independence (X₁) of the unit will add to the value of mathematical ability test (Y ̂) of 6.019. Average each additional variable of mathematical communication skills (X₂) of the unit will occur the value addition of mathematical communication ability test (Y ̂) of 5.561.
