SIMULASI FILTER KALMAN UNTUK ESTIMASI SUDUT DENGAN MENGGUNAKAN SENSOR GYROSCOPE Wahyudi, Wahyudi; Susanto, Adhi; Pramono H, Sasongko; Widada, Wahyu

The Kalman filter is a recursive solution to the process linear filtering problem that can remove the noisefrom signal and then the information can useful. The process that use Kalman filter must be approximatedas two equations of linear system, state equation and output equation. Computation of Kalman filter isminimizes the mean of the square error. This paper explore the basic consepts of the Kalman filteralgorithm and simulate its to filter data of gyroscope to get a rotation. The measurement noise covariancedetermines how much information from the sample is used. If measurement noise covariance is high showthat the measurement isnâ€™t very accurate. The process noise covariance contributes to the overalluncertainty of the estimate as it is added to the error covariance matrix in each time step. If the errorcovariance matrix is small the Kalman filter incorporates a lot less of the measurement into estimate ofrotation.

Frekuensi signal radar sekunder yang sedang dikembangkan hanya terdiri dari satu buah saja. Oleh karena itumemerlukan bandpass filtering yang sangat tajam, supaya jika ada noise maka dapat dihilangkan. Tulisan inimengaplikasikan Fourier filter untuk eliminasi noise signal radar tersebut, sehingga dapat meningkatkan akurasi perhitunganjarak. Frekuensi bandpass filter adalah 3.5 kHz untuk deteksi peluncuran roket jarak jauh (>100 km). Hasil yang diperolehmenunjukkan hasil yang sangat bagus dalam merekonstruksi kembali signal yang telah tercampur noise

The results of previour research Wahyu (2001-2009), found the reinforce and complement the theory of Cognitive Development (Scheme) student (Extended Level Triad++) in the learning of mathematics. The purposes of the study are: 1) to generate a new theory about the Extended Level Triad++ ie levels of development schemes student to Graph Theory finer (from five levels to seven levels); 2) to determine the characteristics of the new levels of the triad (the Triad Level Extended++). In the qualitative research, data were collected from a task-based interview, then performed the data reduction, and presentation of data, as well as the next steps as set out in the flowchart prosesur collection and analysis of data, the data analysis will apply genetic decomposition analysis. Then to get a characterization of each level of the development carried out by the method-comparison analysis-fixed, by applying the theory of Glaser & Strauss, a theorizing process through four stages. The results of this study obtained in the form of advanced theory Extended Level Triad++. The theory is then summarized in a network schema development consisting of seven levels, ie the level of pre-intra, intra, semi-inter-level, international level, the level of semi-trans, trans level, and the level of extended- trans. Keywords: Extended Trans, Development Scheme, Triad Level

This article explains the results of research on the influence of everyday mathematics learning models on critical thinking skills of Class XI students of SMA Negeri 4 Seluma in the 2019/2020 Academic Year. This type of research is experimental research with quasi experimental. This research was conducted at SMAN 4 Seluma in the odd semester of the 2019/2020 school year with a population of all class XI and sample classes XI MIA1, XI MIA2, XI MIA3, and XI IIS2. Research data were analyzed using Ancova test. The results showed that there were differences in critical thinking skills between students taught with everyday mathematics and conventional learning models after controlling students' initial abilities with p-value = 0.00 <0.05, there were differences in critical thinking between students whose cognitive styles were Field Independent (FI), and Field Dependent (FD) cognitive style after controlling students 'initial abilities with p-value = 0.00 <0.05, there is an influence of learning model interaction and cognitive style on critical thinking skills after controlling students' initial abilities with grades p-value = 0.00 <0.05, there is a linear influence of students 'initial covariate ability on critical thinking skills with p-value = 0.00 <0.05, students' initial ability, everyday mathematics learning model and cognitive style together - the same effect on critical thinking skills p-value = 0.00 <0.05

Infinite series is one of the difficult calculus material for students. It needs to be analyzed the cognitive activities of students to make it easier for lecturers to arrange learning plans. The purpose of this study is to describe the characteristics of the trans level about infinite series. The subject of this research was a student of Mathematics Education, one of the universities in Bengkulu. A total of 5 people were selected from 29 students based on their cognitive abilities. Subjects were interviewed based on the assignment given. Data is analyzed through its genetic decomposition. The results of the study are that subjects can coordinate other objects and processes, so that the scheme is formed about the convergence of infinite series and sequences. Conclusion: the subject is able to do thematization so that forming a mature scheme is a trance level characteristic.
