Penyelesaian Numerik Persamaan Diferensial Orde Dua Dengan Metode Runge-Kutta Orde Empat Pada Rangkaian Listrik Seri LC

One alternative to solve second order differential equations by numerical methods, specificallynon-liner differential equations is the Runge-Kutta fourth order method. The Runge-Kutta fourth ordermethod is a numerical method that has high degree of precision and accuracy when compared to othernumerical methods. In this paper we will discuss the numerical solution of second order differentialequations on LC series circuit problem using the Runge-Kutta fourth order method. The numericalsolution generated by the computational calculation using the MATLAB program, the strong current andcharge are obtaind from t = 0 and t =0,5 second and different step size value

KETAKSAMAAN INTEGRAL GRONWALL-BELLMAN UNTUK FUNGSI BERPANGKAT

Integral inequality of Gronwall-Bellman is known as an integral inequality which consists of differential and integral forms. Integral inequality of Gronwall-Bellman involving several functions that some definite condition hold and integral values of these functions. In addition, the integral inequality of Gronwall-Bellman shows that if a function is bounded to a certain integral values then that function is also bounded for the other conditions, that is the exponential of integral. Furthermore, by adding some specific conditions the integral inequality of Gronwall-Bellman can be extended to the case of power functions

PELATIHAN PENGGUNAAN MEDIA PEMBELAJARAN ONLINE YANG TERINTEGRASI GOOGLE SUITE BAGI JEMAAT GPM IMANUEL OSM

Salah satu kebijakan pemerintah dalam memutus mata rantai Covid-19 dalam bidang pendidikan adalah dengan pemindahan proses belajar mengajar yang dilakukan di sekolah menjadi dilakukan di rumah. Kegiatan proses belajar mengajar seperti ini sekarang lebih dikenal dengan metode pembelajaran dengan sistem online. Penerapan metode pembelajaran dengan sistem online ini menuntut pendidik dan peserta didik tak terkecuali orang tua untuk memanfaatkan teknologi yang ada agar proses belajar mengajar di masa pandemi dapat berjalan dengan baik. Salah satunya dengan memanfaatkan platform berbasis website yang terintegrasi dengan Google Suite. Platform yang terintegrasi Google Suite yang sering digunakan sebagai aplikasi pembelajaran online, yaitu Google Classroom, Google Meet dan Google Form. Aplikasi-aplikasi tersebut sering digunakan karena tidak berbayar dan sederhana dalam mengoperasikannya. Peran orang tua dalam mendampingi, bimbing selama proses pembelajaran online bagi peserta didik khususnya tingkat sekolah dasar sangat diperlukan. Namun, kendala terbesar yang dihadapi orang tua yaitu keterbatasan pengetahuan dalam mengakses beberapa aplikasi tersebut. Melalui pelatihan penggunaan platform berbasis website yang terintegrasi Google Suite sebagai media pembelajaran online, diharapkan para orang tua serta peserta didik memiliki kecakapan dan pengetahuan yang lebih baik dalam mengakses beberapa aplikasi guna dapat menunjang terlaksananya metode pembelajan dengan sistem online

A Stage-structure Leslie-Gower Model with Linear Harvesting and Disease in Predator

The growth dynamics of various species are affected by various aspects. Harvesting interventions and the spread of disease in species are two important aspects that affect population dynamics and it can be studied. In this work, we consider a stage-structure Leslie–Gower model with linear harvesting on the both prey and predator. Additionally, we also consider the infection aspect in the predator population. The population is divided into four subpopulations: immature prey, mature prey, susceptible predator, and infected predator. We analyze the existences and stabilities of feasible equilibrium points. Our results shown that the harvesting in prey and the disease in predator impacts the behavioral of system. The situation in the system is more complex due to disease in the predator population. Some numerical simulations are given to confirm our results

Village Grouping In Southwest Maluku District Based On Poverty Characteristics Using Self Organizing Maps (SOM) Methods

Poverty is one of the fundamental problems that has become the center of attention of the Maluku Provincial government, especially Southwest Maluku Regency. This study aims to provide information to the government about village grouping based on poverty characteristics in Southwest Maluku Regency using the Self Organizing Map network method. In this network, a layer containing neurons will arrange itself based on the input of a certain value in a group known as a cluster. In the grouping process, 3 results were obtained with the best grouping II results because they had the smallest standard deviation ratio value

Perancangan Sistem Deteksi Plagiarisme Skripsi (Judul Dan Abstrak) Berbasis Matlab Menggunakan Algoritma Winnowing

Plagiarism is an act of plagiarizing the work of others who will then acknowledge the work as one's own work without mentioning the source of the work. This research aims to create a plagiarism detection system using the winnowing algorithm in MATLAB to prevent plagiarism in the final project of the Mathematics Department students. In order to get the best k-gram value and window size that will be used in the system, a testing process is carried out between document I (100% data) and document II (80% data) by using variations in k-gram values ​​and window sizes. The test results show that the best k-gram ​​and window size are 12 and 4

Optimization OPTIMIZATION OF ASSIGNMENT PROBLEMS USING HUNGARIAN METHOD AT PT. SICEPAT EXPRESS AMBON BRANCH (LOCATION: JAVA CITY KEC. AMBON BAY)

One of the special cases of problems in linear programming that is often faced by a company in allocating its employees according to their abilities is the assignment problem. The assignment problem can be solved using the Hungarian Method. In applying the Hungarian method, the number of employees assigned must be equal to the number of jobs to be completed. In this study, the Hugarian method was used to optimize the delivery time of goods from PT. SiCepat Express Ambon Branch – Java City. To solve the assignment problem at PT. SiCepat Express Ambon Branch – Java City, the required data includes employee names, destination locations, and delivery times. Before using the Hungarian method, the total delivery time of 7 employees at 10 destinations is 955 minutes. However, after using the Hungarian method, the total delivery time of 7 employees at 10 destination locations was 440 minutes. It can be seen that there are 515 minutes of time effisiency. We also Solved this assignment problem uses the QM For Windows Version 5.2 software and go the same amount of time, which is 440 minutes. &nbsp

Penggunaan Perangkat Lunak Matematika Berbasis Website Dalam Pembelajaran Matematika Kontekstual Untuk Siswa SMA Negeri 6 Maluku Tengah

Pendidikan diakui memiliki potensi untuk mengubah status sosial dan juga ekonomi suatu bangsa. Sebagai sarana utama bagi peserta didik untuk meningkatkan pengetahuan mereka dalam berbagai ilmu, sekolah dianggap sebagai lembaga pemerintah yang krusial. Seiring dengan pesatnya perkembangan teknologi, seluruh elemen masyarakat, terutama siswa tingkat menengah atas, dihadapkan pada tuntutan untuk beradaptasi. Ini disebabkan oleh kebutuhan yang terus berubah di masyarakat dan perkembangan teknologi yang semakin canggih. Oleh karena itu, perlu adanya peningkatan kualitas pembelajaran matematika di Sekolah Menengah Atas (SMA). Pendekatan pembelajaran kontekstual (Contextual Teaching and Learning/CTL) adalah salah satu metode yang bisa digunakan. Pendekatan ini dimulai dengan menggunakan situasi dunia nyata yang dialami siswa sebagai landasan pembelajaran, kemudian mengintegrasikannya ke dalam konsep matematika yang akan dipelajari dan dibahas. Dalam kerangka ini, pemanfaatan kemajuan teknologi dalam pembelajaran matematika memiliki potensi untuk meningkatkan pencapaian siswa dan mengasah keterampilan sosial siswa, dengan menggunakan perangkat lunak matematika yang berbasis grafis. Penggunaan perangkat lunak ini dalam implementasi pembelajaran berpendekatan kontekstual dianggap lebih efektif dalam meningkatkan pemahaman siswa jika dibandingkan dengan pendekatan pembelajaran ekspositori
