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.

Tujuan penelitian ini adalah mendeskripsikan secara komprehensif perbedaan bukti yang membuktikan dan bukti yang menjelaskan berdasarkan pertimbangan implikasi kedua bukti tersebut sebagai dasar konstruksi penalaran dan bukti dalam matematika. Kajian dijalani dengan kegiatan menguraikan perbedaan spesifik antara keduanya serta memberikan contoh kasus kedua bukti, dan memberikan justifikasi atas pentingnya pengenalan kedua bukti dalam kelas matematika. Kedua bukti digambarkan dengan permasalahan konsep barisan bilangan ganjil. Bukti yang membuktikan hanya menunjukkan dengan menggunakan induksi matematis, sementara bukti yang menjelaskan menunjukkan dengan bukti Gauss, representasi geometrik bangun titik, dan garis zig-zag. Perbedaan antara keduanya tampak pada pemberian alasan yang berasal dari bukti itu sendiri. Hasil kajian mengindikasikan bahwa peran bukti dalam kelas matematika pada tingkat perguruan tinggi adalah membuktikan/meyakinkan, pada tingkat menengah atas adalah membuktikan dan menjelaskan, dan pada tingkat sekolah menengah pertama dan dasar peran utamanya adalah menjelaskan. Akibatnya bukti matematis tidak hanya membuktikan/menyakinkan, melainkan juga menjelaskan. Karenanya penting mempertimbangkan implikasi bukti dalam kurikulum matematika di sekolah, serta perlunya menyajikan bab materi kepada mahasiswa pendidikan matematika tidak hanya bukti yang membuktikan, melainkan juga bukti yang menjelaskan.Proofs that Prove and Proofs that Explain in Mathematics ClassroomAbstractThe purpose of this study was to comprehensively describe the differences of the proofs that prove and proofs that explain based on the consideration of the implications of the two proofs as the basis for the construction reasoning and proofs in mathematics. The study was undertaken with the activity of describing the specific differences between the two and providing examples of cases of both proofs; and provide justification for the importance of introducing both proofs in mathematics classrooms. Both proofs are illustrated by the problem of the odd number sequence concept. Proofs that prove is only shown using mathematical induction, while proofs that explain shows with Gaussian proof, a geometric representation of point shape, and zigzag line. The difference between the two appears to be the reasoning that comes from the proof itself. The results of the study indicate that the role of proof in mathematics classes at the tertiary level is proving/convincing, at the senior secondary level it is proving and explaining, and at the junior and elementary school level its main role is explaining. As a result, mathematical proof does not only prove/convince, but also explain. It is therefore important to consider the implications of proof in the mathematics curriculum in schools, as well as the need to present chapter materials to mathematics education students not only proofs that prove but also proof that explain.

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.
