Abstract

Every year the admission of new students with various backgrounds implies that students have different abilities. The difference in student abilities corresponding to student learning habits. Student learning habits maybe different if viewed from the gender and student's years class. Based on differences of student abilities is necessary to conduct research to determine the relationship between student's years class and gender toward student learning habits. This study was an ex post facto study with a sample of 203 students as the sample was selected by simple random sampling technique. Based on analysis of variance statistical analysis of two paths obtained by students' learning habits do not different in terms of gender this can be seen from Fscore = 0.008 with sig = 0.93 > 0.05, while students' learning habits are different if viewed from the year of the student's class this can be seen of the value Fscore = 3.537 with sig = 0.008 < 0.05. Post hoc test indicated that students’ 10th semester difference with student 4th semester and 2th semester. Students 2th semester difference with 6th semester and 8th semester.

Abstract

Students usually have difficulties in visualizing images that are caused by the lack of students’ conceptual understanding. We need learning which is able to help the students’ conceptual construction. One of them is by using technology in learning. This study aimed to develop students’ worksheets using a scientific approach based on GeoGebra for the eleven-grade of senior high school in Mataram-Indonesia. This study type was Research and Development (RD) using Plom model. The developed product was validated by experts and tested for its practicality by mathematics teachers and students. The quality of the product refers to the validity and effectiveness of the product. The results of expert validation and field try out indicated that the developed worksheet is valid and practical. The result of the research showed that students’ worksheet is valid and effective with validation average score is 4.44 and effective. The students’ average score is 86.84% (above the minimum standard) and the average of students' responses is 87.72% (positive category). It can be concluded that the developed worksheet can be used in the classroom

Abstract

Mahasiswa pendidikan matematika FKIP Universitas Mataram harus mengusai matematika sekolah sebagai bagian dari kompetensi professional calon guru. Fakta menunjukkan pemahaman matematika mahasiswa sangat rendah sehingga penting untuk mendapatkan data tentang kriteria faktor-faktor internal yang mempengaruhi tingkat pemahaman matematika sekolah mahasiswa pendidikan matematika FKIP Unram. Untuk itu dilakukan penelitian deskriptif kuantitatif dengan populasi mahasiswa pendidikan matematika angkatan 2015 sampai 2019 dengan sampel sebanyak 214 mahasiswa dipilih dengan metode Cluster Random Sampling. Berdasarkan hasil analisis diperoleh sikap mahasiswa terhadap matematika berada pada kategori positif dengan rata-rata 80,7, Minat mahasiswa terhadap matematika berada pada kategori sangat tinggi dengan rata-rata 64,9,  motivasi berprestasi mahasiswa berada pada kategori sangat tinggi dengan rata-rata 112,9, dan kebiasaan belajar mahasiswa berada pada kategori baik dengan rata-rata 58. Korelasi antara masing-masing faktor diperoleh minat mahasiswa memiliki korelasi yang kuat dengan kebiasaan belajar yaitu 0,61 sedangkan faktor-faktor internal lain memiliki korelasi sedang dan sikap terhdap kebiasaan belajar memiliki korelasi lemah. Berdasarkan data-data terkait dengan sikap, minat, motivasi berprestasi, dan kebiasaan belajar menunjukkan hal yang positif disebabkan karena sampel penelitian adalah mahasiswa program studi pendidikan matematika. Sehingga perlu diadakan penelitian lanjutan untuk mendapatkan faktor lain yang menyebabkan rendahnya pemahaman mahasiswa pendidikan matematika terhadap matematika sekolah.

Abstract

Cipher hill adalah algoritma cipher poligrafik berdasarkan transformasi linear, yang ditemukan oleh Lester S. Hill pada tahun 1929. Algoritma cipher Hill mengenkripsi plainteks dengan kongruensi linier C≡KP(mod 26) dan mendekripsi cipherteks dengan kongruensi linier P≡K^(-1) C(mod 26). Enkripsi atau enciphering adalah proses mengubah plainteks (pesan asli) menjadi cipherteks (pesan tersandi), sementara proses balik mengubah cipherteks kembali menjadi plainteks oleh penerima yang dituju, disebut dekripsi atau deciphering. Banyak kode atau karakter dalam cipher Hill adalah sebanyak huruf dalam alphabet (A, B, C, ..., Z). Jumlah atau banyak karakter kode dalam cipher Hill, sangat berpengaruh terhadap kekuatan suatu cipher, sehingga diperlukan modifikasi dengan menambahkan atau mengganti karakter kode dengan karakter kode ASCII (American Standard Code for Information Interchange) (desimal) 33-126.
