Abstract

Salah satu bentuk interaksi makhluk hidup di bumi ini adalah predasi, yang secara matematis dapat disajikan dalam model Lotka-Volterra. Dalam penelitian ini, dikaji model dinamik diskrit Lotka-Volterra yang diperoleh dengan menggunakan metode skema beda hingga tak standar. Perilaku dari titik kesetimbangan model bersifat stabil asimtotis lokal jika memenuhi syarat masing-masing titik kesetimbangan. Perubahan nilai parameter akan memberikan pengaruh pada perubahan kestabilan titik kesetimbangan. Analisis sensitivitas terhadap koeksistensi titik kesetimbangan dilakukan secara numerik. Kenaikan tingkat kompetisi antar predator dan tingkat interaksi predator terhadap prey mengakibatkan kenaikan jumlah populasi predator.Kata kunci: model lotka-volterra, metode skema beda hingga tak standar, titik kesetimbangan, analisa kestabilan.

Abstract

Developing a video for learning mathematics in the Number Theory course as the purpose of this research. This needs to be done to help students understand the material during online learning. The development procedure in this R&D research is based on the ADDIE product development model (analyze, design, development, implementation, evaluation). The stages of this research are limited to the development and trial stages. Furthermore, at the trial stage, one class is carried out to take the Number Theory course in the odd semester for the Academic Year 2021-2022. The results of this study are (1) several learning videos have been formed in the Number Theory course based on sub-materials; (2) the learning video media is declared feasible based on the results of the assessment from a team of experts consisting of two validators, the results obtained from four aspects, namely the material aspect, language and image aspects, presentation aspects, and finally the display aspect with a final average score of 75 with appropriate criteria; and (3) the results of the trial obtained the results of the completeness test, the average score was 75.28 and the comparative test results obtained the average value. The mean of completeness of the experimental class and the control class were 75.28 and 60.28. The value of the experimental class is better than the control class.

Abstract

The objectives of this study were to: (1) describe the perceptions of students in the Mathematics Study Program of the Faculty of Science and Technology, Purwokerto University of Nahdlatul Ulama (UNU) on learning interactions between students and students and students and lecturers; (2) describe the perceptions of students in the Mathematics Study Program of UNU Purwokerto about the learning environment in online learning. The subjects of this study were students in the 2nd and the 4th semester of the Mathematics Study Program of UNU Purwokerto. This research was conducted in April - June 2020. The data in this study were obtained from questionnaires and interviews. . The subjects in this study were taken by purposive sampling technique. The data validation used the triangulation method. Data analysis techniques used data reduction, data presentation, and drawing conclusions. The results showed the following: 1) students had difficulty in interacting with fellow students and lecturers in online lectures. This is evidenced by the high level of presentation which shows disagreement with the statement that says student interaction in online lectures has gone well; 2) students response to the learning environment in online lectures, it can be concluded that the learning environment in online lectures has not supported students to learn.

Abstract

Some generalizations of Banach's contraction principle, which is a fixed-point theorem for contraction mapping in metric spaces, have developed rapidly in recent years. Some of the things that support the development of generalization are the emergence of mappings that are more general than contraction mappings and the emergence of spaces that are more general than metric spaces. The generalized Kannan type mappings are one of the mappings that are more general than contraction mappings. Furthermore, some of the more general spaces than metric spaces are b-metric spaces and modular b-metric spaces, which bring the concept of b-metric spaces into modular spaces. The fixed-point theorems for generalized Kannan-type mappings on b-metric spaces have been given. Therefore, this research aims to define generalized Kannan-type mappings on modular b-metric spaces and provide fixed point theorems for the generalized Kannan-type mappings on complete modular b-metric spaces. The definition of generalized Kannan type mapping in modular b-metric spaces is given by generalizing generalized Kannan type mappings in b-metric spaces. Then, the proof of fixed-point theorems for that mapping in modular b-metric spaces is carried out analogously to the proof of the fixed-point theorems for that mapping given in b-metric space. In this article, we obtain the definition of Kannan-type mappings and fixed-point theorems for generalized Kannan-type mappings in modular b-metric spaces and some consequences of the fixed-point theorem. In proving the theorem, a property of altering distance functions in b-metric spaces is generalized into modular b-metric spaces.

Abstract

Pengembangan media pembelajaran di bidang pendidikan sesuai dengan perkembangan zaman diperlukan. Kemampuan dalam pengembangan tersebut sangat dibutuhkan oleh para guru dalam berbagai tingkat pendidikan pada era digitalisasi ini. Kurangnya kemampuan adaptasi para guru dalam mengikuti perkembangan berbagai jenis media pembelajaran pada era ini adalah salah satu kendala yang dijumpai para guru dalam pengembangan media pembelajaran. Fenomena tersebut terjadi di Lingkungan Musyawarah Guru Mata Pelajaran (MGMP) Matematika SMK Kabupaten Bannyumas. Salah satu perangkat lunak yang digunakan dalam pengembangan media pembelajaran adalah Microsoft Word. Dalam pelatihan penulisan media pembelajaran pada Microsoft Word yang berfokus pada Mata Pelajaran Matematika ini, peserta diperkenalkan dengan penulisan equation menggunakan Bahasa LaTeX dalam berbagai materi di Mata Pelajaran Matematika tingkat SMK. Metode yang digunakan dalam pelatihan ini adalah diskusi dan tanya jawab. Penulisan dengan Bahasa LaTeX ini dapat mempersingkat waktu penulisan pada Microsoft Word sehingga meningkatkan keefisienan waktu bagi para guru dalam mempersiapkan Kegiatan Belajar Mengajar.

Abstract

The Covid-19 pandemic has caused the learning process to be hampered and cannot be carried out face-to-face. Therefore, a solution is needed for this problem. One alternative to overcome this problem is online learning. This study aims to describe the effectiveness of online learning using online media during the Covid-19 pandemic in Mathematics courses. The subjects of this study were 51 students in the Faculty of Science and Technology, Nahdlatul Ulama University, Purwokerto. They were from five different study programs, namely Agrotechnology, Mathematics, Biology, Fisheries Science, and Agricultural Biosystems Engineering, who had taken mathematics courses. This study was carried out in June – August 2021. This study used closed, semi-closed, and open-ended questionnaires as research instruments. Then, the data collection procedure was done through Google Forms. The data obtained were then selected using purposive sampling. To get valid and reliable data, triangulation was applied in this study. Triangulation was carried out through interviews with five students whose data were selected randomly. The researchers used descriptive statistics as the data analysis. The study found that the activities most often carried out by students during Study From Home (SFH) are playing on cellphones or laptops, doing assignments, working, and sleeping. Then, related to online learning, students prefer to use WhatsApp Group media and lectures. The preferred assignments or assessments are individual assignments and quizzes. Furthermore, the learning model most favored by students is the face-to-face learning model because students consider online learning ineffective. The results of this study can be used as a reference in choosing the suitable model, method, and learning media. Therefore, online learning can be held effectively and easily accepted by students during the Covid-19 pandemic.
