Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui aktivitas menulis matematis siswa kelas VIII SMP ditinjau dari gaya kognitif Field Dependent dan gaya kognitif Field Independent. Metode penelitian yang digunakan adalah metode deskriptif. Teknik pengumpulan data yang digunakan adalah teknik tes tertulis. Hasil  analisis data menunjukkan bahwa siswa yang memiliki gaya kognitif Field dependent pada indikator drawing, secara umum hanya bisa membuat gambar tetapi tidak bisa memberikan keterangan pada gambar yang dibuat; pada indikator mathematic expressions, secara umum  hanya bisa menuliskan rumusnya saja; pada indikator written test secara umum belum bisa menuliskan  pendapatnya. Sedangkan siswa yang memiliki gaya kognitif Field Independent  pada indikator drawing, secara umum  bisa membuat gambar dan memberikan keterangan yang sesuai pada gambar yang dibuat; pada indikator mathematic expressions, secara umum sudah bisa membuat model persamaan; pada indikator written test secara umum  bisa menuliskan pendapatnya. Kata kunci : Aktivitas menulis matematis, Gaya kognitif, Komunikasi Abstract: This research aims to know writing activity mathematics of eighth grade students in terms of field dependent and field independent cognitive styles. This research used descriptive method. The data collection technique is using the written test technique. The data analysis result shows that students with field dependent cognitive style for drawing indicator, generally students only can draw a picture but can`t give information based on the picture; for  mathematics expressions indicator, generally students just can writing the formula; for  written test indicator, generally students not yet writing their opinions. While students with field independent cognitive style for drawing indicator, generally students can draw a picture and add information based on the picture; for mathematics expressions indicator, generally students can make an equation model; for written test indicator generally students can writing their opinions. Keywords: Mathematics writing activity, Cognitive Style, Communication

Abstract

The use of electric vehicles is now supported by a braking Development increasingly advanced technology rapid bring impact on various sectors, including sector trade. One of the affected sectors impact is trading product electronics. Products electronic be one of the most popular products among the public Because need will increasingly advanced technology increased. MK Store is having trouble in predict sale product electronic best seller, then from That done study optimization planning provision stock product electronics at MK Store with use prediction sale product electronic best seller. With implementing prediction models sale product electronic best seller at MK Store using data mining methods for optimize planning supplies stock product electronics at MK Store with use prediction sale product electronic best seller, and implementing a prediction model sale product electronic best seller at MK Store developed use K-Nearest Neighbor method in provision product electronics. Using The K-Nearest Neighbor algorithm is believed to can give very accurate results with count use distance neighbor nearest , and use variable 10 variables For predicted . Using the Orange tool because can make it easier in operate with use between drag-and-drop face create channel work, data analysis and own diverse widgets components that include data processing, modeling predictive, visualization and analysis text. The result of research conducted use the K-Nearest Neighbor algorithm produces mark with correlation positive (excellent), and the results prediction product electronic best seller at MK Store namely Magicom/Rice Cooker. With existence study This expected for study next, recommended expand range with develop criteria new and considering use method alternative.
