Dinamika pembalikan magnetisasi pada nanoblock berbasis kobalt teredam kuat yang distimulasi oleh pemanasan pulsa telah dieksplorasi secara numerik untuk model parallelepiped dengan ukuran 50×50×20 nm3. Pengaturan simulasi diimplementasikan untuk mengevaluasi dua parameter penting dalam perekaman magnetik dengan bantuan panas, yaitu stabilitas termal, dan konsumsi medan tulis. Stabilitas termal diukur melalui medan magnet induksi yang meningkat secara linear hingga 2 Tesla selama 2,5 ns pada kesetimbangan termal terhadap lingkungan. Dalam simulasi sistem dengan stimulasi medan panas, konsumsi medan tulis diselidiki menggunakan dua jenis pulsa, yaitu medan magnet, dan pulsa medan termal. Simulasi ini didasarkan pada persamaan Landau-Lifshift-Gilbert yang memasukkan teorema disipasi fluktuasi dalam menghitung efek fluktuasi termal. Selain itu, parameter-parameter material yang tergantung suhu, yaitu saturasi magnetik, anisotropi magnetik, dan interaksi pertukaran, juga diperhitungkan. Sebagai hasilnya, nanoblock berbasis kobalt yang teredam kuat memiliki penghalang energi magnetik yang tinggi untuk mencegah batasan superparamagnetik. Selain itu, medan penulisan dapat dikontrol melalui pengaturan periode pemanasan, dan juga melalui manipulasi sifat magnetik seperti redaman magnetik intrinsik.

Most students think that the hardest subject to understand is math. It happened when the student did not get the meaning of doing math. It was made worse by the covid situation, students more and did not get any value. Even though the government had provided curriculum and lesson method options to be held in class, still it can be maximized to create meaningful math lessons. Therefore, this research focuses on the application of the Project-Based Learning (PjBL) method based on a prototype curriculum to make math lessons more meaningful. The research method that will be used is descriptive qualitative. Students must get meaningful math lessons to find the greatness of God by doing math in their daily lives. Finally, students also glorify God. The research result is, PjBL based on the prototype curriculum method can help make learning mathematics more meaningful. The writer suggests for schools, hold training on using PjBL based on the curriculum prototype method, for teachers to apply this method in abstract topics, and for the next researcher to research the application of the PjBL method based on another curriculum.

The problem that occurs at Bank Negara Indonesia of Medan Industrial Area Branch Office is the occurrence of unemployed tellers at certain hours. The purpose of this study is to determine the queue system at Bank Negara Indonesia of Medan Industrial Area Branch Office and to find out the optimal number of tellers at the bank. The structure of the queue model that occurs at Bank Negara Indonesia of The Medan Industrial Area Branch Office is a Multi Channel-Single Phase by applying the discipline of the First Come First Serve queue. The bank has 4 tellers with an average customer arrival value (λ) of 20 people per hour and an average service level (μ) of 22 people per hour. The results of data processing show the arrival pattern of Poisson-distributed customers and the general distribution service pattern. This study resulted in a queueing model (M / G / 4): (FCFS / ∞ / ∞). The optimal number of tellers in providing customer service is to reduce 1 teller. Based on the calculation results with only 3 tellers, it can reduce the probability of the teller being unemployed from the initial one by 40.25% to 39.97%.

The purpose of this study was to analyze the achievement of each indicator that measures the mathematical understanding ability of high school students in the learning of Relations and Functions. This research is a qualitative descriptive study that seeks to describe students' mathematical understanding abilities. The subjects of this study were 10th Grade students in SMAN 2 Sintang which consisted of 30 students. The data collection method used is a matter of test material relations and functions. Based on the results of the study, it can be concluded that the level of ability of students in high school mathematics subjects is as follows: there is 1 student who scores below 50, there are 3 students who score between 51 and 60, there are 8 students who score between 61 and 70, there are 9 students scored between 71 and 80, there were 9 students who scored 81 and above. The perfect score was achieved by 30 students in the first question number. All partisipants got different results, the first indicator of students getting the fulfillment of the indicator of ability to understand concepts with very good categories, the second indicator of the fulfillment of indicators of understanding ability concept with sufficient category and the third indicator students get the fulfillment of the indicator of ability to understand concepts with very poor category. It can be said that students still have difficulty in solving problems in the form of distinguishing examples from non-examples and solving problems using concepts when solving problems.

This research is motivated by the number of students who make errors in solving trigonometry problems. This can be seen from the low average value of daily trigonometry tests for class X students of SMA Ekasakti Padang in the 2021/2022 school year. Teachers were necessary to know in advance what caused the student's mistakes. This study aims to (1) determine the causes of errors in class X SMA Ekasakti Padang in solving trigonometry problems, and (2) determine the percentage of errors made by class X students at SMA Ekasakti Padang in solving trigonometry questions. This type of research is descriptive. The research subjects in this study were students of class X SMA Ekasakti Padang. Data analysis in this study was divided into two, namely (1) written test results data were analyzed by calculating the percentage of students who made mistakes in solving trigonometric questions, and (2) interview data analysis was carried out by reducing data, presenting data, and concluding. The mistakes made by students in solving trigonometry problems are conceptual errors and algorithm errors. Conceptual errors were made by 83.33% of students, where the most incorrect concept was the triangle concept. Furthermore, the principle error is 66.67%, and the algorithm error is 50%. The causes of errors made by students in solving trigonometry problems are carelessness and haste, poor understanding of students on questions, lack of understanding of prerequisite concepts related to questions, and interpretation of the meaning of the questions incorrectly or incorrectly in reading the questions.

Determination of the shortest path or the fastest travel time is a problem that occurs to drivers of trucks loaded with fuel oil (BBM) when delivering their tanks to one of the public refueling stations (SPBU) in Pal Lima. To get to the destination, several paths that can be passed. This study aims to determine the shortest path and fastest travel time using Dijkstra's algorithm. Dijkstra's algorithm can be used on both directed and weighted graphs. The first step that must be done is to determine the starting node and destination node. After that, the calculation is carried out from the initial departure node to the neighboring node, the node with the smallest weight is used as the next calculation node. The same is done until all nodes are evaluated. Crossroads are assumed as vertices and between intersections as edges in Dijkstra's algorithm. From the results of the study, the shortest path was obtained through the Kapuas 2 Toll Road, Jl. Adi Sucipto, Jl. Imam Bonjol, Jl. Tanjung Pura, Jl. Rahadi, Jl. Mr. Love, Jl. Hassanudin, Jl. H. Rais, Pal III, Pal V with a minimum distance of 12,768 Km. For the fastest route, it is through the Kapuas 2 Toll Road, Jl. Major Alianyang, Jl. Arteri Supadio, Jl. General Ayani, Jl. Abdurrahman, Jl. Sultan Syahrir, Dr. Sutomo, Jl. Dr. Wahidin, Jl. Pal V with the fastest travel time of 27 minutes.
确定最短路径或最快的旅行时间是在Pal Lima的一个公共加油站(SPBU)装载燃料油(BBM)的卡车司机在将油箱运送到其中一个加油站时遇到的问题。要到达目的地，可以通过几条路径。本研究旨在利用Dijkstra算法确定最短路径和最快旅行时间。Dijkstra算法可用于有向图和加权图。必须完成的第一步是确定起始节点和目标节点。之后，从初始出发节点向相邻节点进行计算，取权值最小的节点作为下一个计算节点。直到计算完所有节点为止，都是这样做的。Dijkstra算法将十字路口作为顶点，十字路口之间作为边。从研究结果来看，最短路径是通过卡普亚斯2收费公路，jr .。Adi Sucipto, jr。小伊玛目邦乔尔Tanjung Pura, jr .Rahadi,杰。小爱先生。Hassanudin,杰。H.
