Algoritma yang ditemukan Warshall ini untuk mencari rute terpendek. Jenis penelitian ini adalah kualitatif deskriptif dengan pendekatan studi kasus. Studi kasus meneliti kasus tertentu yang ada di dalam masyarakat yang dilakukan secara mendalam untuk mempelajari latar belakang, keadaan dan interaksi yang terjadi. Hasil penelitian ini adalah mendapatkan rute terpendek menuju Air Terjun Waimarang dengan menggunakan Algoritma Floyd-Warshall di Sumba Timur. Tahap awal dari pencarian Rute Terpendek yaitu dengan mencari rute-rute yang menuju ke Air Terjun Waimarang dengan jarak, waktu dan biaya yang lebih sedikit. Titik-titik yang ada kemudian saling dihubungkan sesuai dengan jalan yang dilewati oleh kendaraan sehingga menjadi suatu jalur. Kemudian jalur yang sudah terbentuk dibuat matriks ketetanggaan dan dihitung menggunakan Algoritma Floyd-Warshall sehin...

This research uses Research and Development method of Borg and Gall model with the last 4 step deduction, grouped in preliminary stage (petition and problem, information gathering), development stage (product design, design validation, design revision), Phase evaluation (product trial). The trial target of the textbook developed is a student of class of 2014 Mathematics Education Study Program IKIP Budi Utomo Malang. The instrument used in this research is validation sheet filled by validator, and student opinion polls filled out by students after trial textbook. The results of the analysis in the preliminary stage shows that the textbook of numerical methods that exist in IKIP Budi utomo Malang is still very minimal, in the process of learning using only one textbook and that too the book used for the engineering study program. Expert judgments on teaching materials developed in the criterion of the prevalence obtained an average score of 86.80 with a percentage of 86.80% so that the textbook developed has a validity criterion is very valid. The effectiveness of textbooks developed was seen from the questionnaire of student opinions obtained after trial textbooks obtained an average score of 42 with 87.5% percentage so that developed textbooks have effective effectiveness criteria.

The learning instruments consist of syllabus, lesson plan, and student worksheet. This research is a development study. This research was conducted in grade 8 of junior high school in Indonesia. This research was implemented in three stages, namely: define, design, and develop. The define phase includes the analysis of syllabus, syllabus, lesson plan, and student worksheet; the design stage includes the preparation of learning instruments draft and research instruments; the development stage includes the test of learning instruments, evaluation and perfection of learning instruments. The validation results of expert validators were as follows: syllabus device with a value of 4.62 with a very valid category, student worksheet instruments with a value of 4.59 with a very valid category, while the materials learning device with a value of...

This research is a qualitative-explorative research that is exploring batik motifs in square and rectangular shapes. The data in this study are in the form of library study data from both documents and electronic media. In addition, in the form of interview records related to Malang batik artwork and observations. The results of the study from this study indicate that: 1) on the kawung motif and Malang written batik there is a square concept; and 2) in Malang’s masked batik motif there is a rectangular concept. The concept of square and rectangle in Malang batik artwork can be applied in mathematics learning. Especially in two-dimentional figure material.

Research paper thumbnail of Development of e-learning mathematics encyclopedia as learning tools for class viii junior high school

The many terms and formulas in mathematics, sometimes make students difficult in learning mathematics. Students often forget to apply a formula to solve certain math problems. To help students in learning mathematics, it is necessary to make a computer software (software) through computer-based learning in the form of a mathematical encyclopedia. The development of e-learning based mathematics encyclopedia that is integrated into learning can be through the development of learning tools. This learning tools can be applied in all devices based online. The use of tools in learning is intended to be able to help overcome various obstacles in the learning process including psychological barriers, physical barriers, cultural barriers...

The mistake was made by both male and female students. In the course, algebraic structure is one of the material that requires the right procedure in its completion. This research includes descriptive analysis with qualitative data analysis. Data collection was carried out by test and interview methods conducted twice, namely TPM 1 and TPM 2. Subjects were considered as 2 students from 35 students of class 2016, consisting of one male student and one female student. The student has high mathematical skills. Each research subject was interviewed regarding the results of his work at TPM 1. To find the credibility of the data, the second test was conducted, which means that this study uses time triangulation. Furthermore, the data were analyzed to determine the types of student errors according to Newman's analysis. Based on the results of the study, data...
