It has impacted all sectors including education. The learning process that initially took place in the school has now been switched virtually. However, this worsens the students understanding in learning mathematics because previously they found it difficulties even in offline learning activities. Describing the learning proces during this pandemic condition is necesary and important to cope with this problem. The problems during this pandemic are related to three domains, namely cognitive, affective and psychomotor. Therefore, a research about this should be conducted. The method was qualitative research by interview and questionnaire. The participants were ten teachers and ten students from different junior high schools in Bukittinggi and Agam. From cognitive aspect, the result found that students could more easily understand the subject matter delivered by the teacher before the pandemic; the percentage of students' understanding of the material learning decreased by 10% during pandemic. From psycomotor aspect, teachers rarely use instructional media during the online learning process; The use of learning media also decreased by 60%, but the percentage of using online media as a learning resource increased by 50%. Moreover, the difficulty of using learning media for student increased by 40%. From affective aspect, teachers are more flexible in giving punishment to students who are not disciplined and educate students’ behaviors before pandemic than during the online learning process. Teacher gives punishment for students who were not disciplined decreased by 50% after virtual class. Overall, assessment done by teacher tends to the cognitive aspects during pandemic.</p> Pipit Firmanti Copyright (c) 2021 Kaunia: Integration and Interconnection Islam and Science https://creativecommons.org/licenses/by-nc-sa/4.0 https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/2736 Fri, 23 Jul 2021 00:00:00 +0700 Development of WEB-Based Correspondence Management Application Programs Faculty of Mathematics and Natural Sciences UNIMED https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/2842 <p><em>Faculty of Mathematics and Natural Sciences which is one of the faculty at Unimed in organizing the activities scheduled and archive mail incoming and outgoing mail is still using manual diary. This&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; is less efficient because it will be difficult to find so many archives of letters that have been stored for a long time. Currently, technological advances in the world are growing rapidly and are very much needed. Especially with the emergence of the Corona Virus Disease (Covid-19) Pandemic, most of the community's activities are disrupted so that activities are carried out online. Likewise with the student activities of FMIPA Unimed. Now students carry out lectures online. However, for final year students who want to apply for a thesis research letter or active students who want to apply for a scholarship need an active college letter, they must come to campus to take care of the files in order to get the required letter. Therefore, there is a need for a correspondence management&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; application in the administration of FMIPA Unimed so that FMIPA Unimed students can take care of the required letters online, employees can speed up searching for mail data and print out their&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; letter reports. This application is designed web-based using PHP and MySQL. This application has the ability to be accessed anywhere by admins, employees and students so that employees can manage mail with a user login, be it adding, updating, deleting, uploading, downloading and searching for letters and printing mail reports. In addition, it also makes it easier for students to take care&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; of research letters and active lecture letters online until the letters are completed and can be downloaded. This application also provides a place to send messages to each other between employees&nbsp;&nbsp; and students.</em></p> Nur Kholiza, Faiz Ahyaningsih Copyright (c) 2021 Kaunia: Integration and Interconnection Islam and Science https://creativecommons.org/licenses/by-nc-sa/4.0 https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/2842 Wed, 15 Sep 2021 00:00:00 +0700 Artificial Bee Colony Algorithm to Solve the Shortest Route Problem with Fuzzy Arc Weight https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/3042 <p>The shortest path problem usually assumes a clear value (crisp) for the weights of each route. However, the crisp weight sometimes ends up ambiguous in practice in the daily life. The number of arc weights is calculated using fuzzy logic, α-cut fuzzy numbers. The Artificial Bee Colony (ABC) algorithm that adopts bee behavior in food searching is used to solve the shortest path problem. This study discusses how to solve numerical problems to find the shortest path using the Artificial Bee Colony algorithm if the arc weights are fuzzy numbers. The algorithm starts with finding the initial solution using Algorithm 1 and then calculated each distance using the sum of α-cut methods. After that, do a local search for each initial solution using the genetic algorithm mutation operator, then searched the distance amount using the same way then compared using the result of distance . The next step was to calculate the fitness value of each solution that would be used to calculate the probability value. The final step was to improve the solution, and an improved solution is said to be a solution if it does not improve again anymore. The calculation process was done repeatedly from the second step to the maximum iteration, i.e. when iteration had reached the limit or the iteration limit fails. Based on the calculation process using ABC algorithm in the case of numerical example, delivery of clean water supply in Gunung Kidul Regency, obtained the shortest route, that is route 1,2,3,5,6 with interval distance equal to 459, 9142.</p> Nani Maryani, Musthofa Muhammad Wakhid Copyright (c) 2021 Kaunia: Integration and Interconnection Islam and Science https://creativecommons.org/licenses/by-nc-sa/4.0 https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/3042 Wed, 15 Sep 2021 00:00:00 +0700 Mathematics Model of Diabetes Mellitus Illness without Genetic Factors with Treatment https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/3043 <p>Diabetes Mellitus is a metabolic disorder characterized by an increase in glucose levels in the blood (hyperglycemia), which causes various chronic complications due to abnormalities in insulin secretion. Diabetes Mellitus is known as the Mother of Disease because it is the mother of various other diseases such as hypertension, heart disease, stroke and blindness. In this paper, what would be studied was a mathematical model of Diabetes Mellitus without genetic factors with treatment, the model used for the approach in this case was in the form of SEIIT. The analysis includes determining the model's equilibrium point, determining the basic reproduction number (R0) and analyzing the stability around the equilibrium point. Furthermore, numerical simulation using MAPLE was given based on the values of the related parameters in the mathematical model that describes the conditions in each subpopulation class.</p> Nurul Fitriyah, Muhammad Wakhid Musthofa, Pipit Pratiwi Rahayu Copyright (c) 2021 Kaunia: Integration and Interconnection Islam and Science https://creativecommons.org/licenses/by-nc-sa/4.0 https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/3043 Wed, 15 Sep 2021 00:00:00 +0700 Best-Beta CAPM (BCAPM) Optimal Portfolio Performance Using EROV, Sortino, and M2 Methods https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/3041 <p>This study discusses the optimal portfolio performance analysis using Best-Beta CAPM (BCAPM) with methods EROV, Sortino, and M2 were applied to stocks sharia incorporated the Jakarta Islamic Index (JII) in the period from October 1, 2014 – August 31, 2017. The results obtained from this study C portfolio showed an optimal portfolio. The proportion of each stock included in the optimal portfolio is stock UNTR (95.27%) and AKRA (4.73%) with a rate of return expected from optimal portfolio is 1.39%, while the risk of an optimal portfolio of 0.066%. Result of consistency test between the performance of stock portfolio with Kendall’s tau test showed that that those methods was consistent in assessing the performance of stocks portfolio.</p> Abdul Aziz, Mohammad Farhan Qudratullah Copyright (c) 2021 Kaunia: Integration and Interconnection Islam and Science https://creativecommons.org/licenses/by-nc-sa/4.0 https://ejournal.uin-suka.ac.id/saintek/kaunia/article/view/3041 Wed, 15 Sep 2021 00:00:00 +0700
