Pengembangan Pendekatan Matriks Hubungan Untuk Pengukuran Similaritas Fera Anugreni; Herman Mawengkang; Marwan Ramli
Jurnal Inotera Vol. 1 No. 1 (2016): July-December 2016
Publisher : LPPM Politeknik Aceh Selatan

Perhitungan similaritas adalah fungsi dasar yang digunakan oleh berbagai aplikasi pengolahan informasi seperti mencari clustering dan klasifikasi. Ada berbagai jenis hubungan dapat digunakan untuk memperkuat nilai kesamaan objek data berpasangan dan untuk membantu meningkatkan kualitas perhitungan kesamaan antara objek data. Hal ini membantu untuk melacak bagaimana hubungan antara objek data yang digunakan untuk mengukur kesamaan objek data. Hasil penelitian ini dapat menunjukkan bahwa Unified Relationship Matrix (URM) dapat digunakan untuk menyediakan data objek heterogen dan hubungan antara masing-masing objek data secara terpadu.

REVIEW MODEL EOQ UNTUK INVENTORI FARMASI RUMAH SAKIT DENGAN ADANYA PERMINTAAN BERVARIASI TERHADAP WAKTU Afnaria Afnaria; Tulus Tulus; Herman Mawengkang; Wiryanto Wiryanto
JISTech (Journal of Islamic Science and Technology) Vol 3, No 1 (2018)

Permintaan merupakan faktor penting guna menentukan jumlah persediaan inventori farmasi di rumah sakit. Sistem inventori farmasi dimana ukuran permintaannya diketahui merupakan sistem deterministik, dan sebaliknya disebut sistem dinamis, dimana permintaan dapat berubah dari waktu ke waktu. Model EOQ merupakan model inventori yang paling sering digunakan sampai saat ini. Model ini mengasumsikan permintaan stasioner sepanjang waktu tak berhingga, dimana inventori dimonitor secara kontinu dan re-order dapat dilakukan kapan saja. Parameter biaya order dan biaya penyimpanan diasumsikan konstan. Namun model ini tidak mengijinkan adanya stockout. Studi ini bertujuan me-review model EOQ dimana permintaannya merupakan fungsi linier terhadap waktu, dengan mengijinkan terjadinya stockout. Ketika terjadi stockout akan dilakukan backorder. Dimana model ini diselesaikan dengan meminimalkan biaya total inventori untuk setiap siklus

JISTech (Journal of Islamic Science and Technology) Vol 3, No 2 (2018)
Publisher : UIN Sumatera Utara Medan

This study aims to determine the effect of student learning outcomes using snake props derived from derivative material functions in class XI of SMA 1 Meranti. The study sample was determined randomly and there were 4 classes available so the study population consisted of 2 classes, each of which consisted of 34 students and XI Science-1 experimental class and class XI Science-2 control class. The test instruments in this study consisted of 5 questions essay tests. From the data analysis the average and standard deviation in the experimental class were obtained to pretest 46,471 and 10,282, while for posttest 74,00 and 10,708. For the average value and standard deviation of the control class to pretest 43,059 and 10,790 and posttest data 66,471 and 10,329. From the data analysis using the t-test at the level of α = 0.05, obtained tcount = 2.951 for t table = 1.668 it turns out ttable < t1-α, then H0 is rejected and Ha is accepted. Thus the conclusion is that there is an influence of student learning outcomes using snake props derived from derivative material functions in class XI of SMA 1 Meranti.

Various information technology-based learning products were created to improve the quality of learning, one of which is online learning media known as e-learning. In addition, during the Covid 19 pandemic, which required learning from home, Mts.Mas Al-Jamiyatul Washliyah Lubuk Pakam was no exception. The use of the E-Learning application in PKM aims to help Mts.Mas Al-Jamiyatul Washliyah Lubuk Pakam in the process of teaching and learning activities. With this application, it is hoped that it can help problems faced by teachers and students outside of class hours, such as lack of communication time between teachers and students, searching for information about the material being taught, and of course to facilitate teachers in providing material to students. The result achieved is the availability of supporting applications for teaching and learning activities that can be obtained regardless of time and place. The conclusion with the existence of E-Learning is that it makes it easier for teachers to provide learning to students outside of class hours such as providing material, easiness in giving assignments and collecting assignments, exams, and facilitating value information.

Sustainable tourism development impacts on many factors, so that a dynamic model approach to tourism research becomes clear in many cases, one of which is in the development of Islamic sustainable tourism. These approaches usually look at a particular problem or the whole picture of tourism. As a result, it becomes difficult to manage tourism towards sustainability. This paper provides an overview of the systems thinking approach to systems analysis using the Causal Loop Diagram (CLD) model for sustainable Islamic tourism planning problems. This study shows that systems thinking has proven to be an effective and powerful tool for explaining the complexity of the tourism system. This has helped simplify, clarify and integrate isolated problems associated with the industry, and provided a mechanism for group learning and decision making to achieve desired results. This paper proposes systems thinking to be used as an appropriate tool for sustainable tourism development. The results of this study can describe the dynamic model of sharia tourism development with the CLD approach so that it can see the influencing factors that indicate causation.

This partnership program was intended to solve problems that arose at SMP Swasta Ar-Rahman Percut such as the lack of teacher skills in developing learning media to foster students’ motivation and implementing online teaching that optimizes the use of technology. In the context of online learning, such difficulties will increase. The solutions offered were training through workshops on the development of interactive virtual reality (VR) using OpenSpace3D and assistance in the implementation. Five stages: Learn, Teach, Evaluate, Acknowledge, and Fostering in the method were held sequentially. Adult learning principles, focusing on experiential learning and self-motivation, were applied to encourage participants and instructors to actively participate. Results showed that the program has made a significant impact on teachers' skills in developing and implementing interactive VR in fun mathematics online learning.

Mitigation is a pre-disaster action that aims to prepare for a disaster situation. One of the mitigation activities is evacuation, which aims to reduce disaster-related losses. Because disaster damage cannot be predicted, dealing with evacuation efforts requires a dynamic model. This study will utilize a dynamic model that combines the game theory model for choosing the evacuation location and the open vehicle routing problem (OVRP) model for selecting evacuation routes to create an intelligent system. The game theory model will be used to supplement the selection of alternate evacuation locations by taking into account geographical features that are very uncertain in the event of a crisis. An evacuation route equipped with an OVRP model with the goal of optimizing travel time is required to mobilize disaster-affected people. With the development of the Intelligent Evacuation System idea, combining the two models will create a new model. The simulation model is evaluated using linear, interactive, and discrete optimizer (LINDO), which may minimize the evacuation time from the evacuation route to a safe destination by 50 minutes if there is no contra-flow to allow more people to be evacuated.

Data Envelopment Analysis (DEA) is the use of non-parametric mathematical programming that is useful for measuring the efficiency of the Decision Making Unit (DMU) of an organization. This study uses the Cooper and Rhodes (CCR) method known as the DEA-CCR multiplier which aims to determine the weight value of each input and output variable of the DMU being evaluated, but it is not sufficient to measure efficiency optimization. To get an efficient value of the weight value of each DMU as a reference to get updated DMU input and output values. So that the DMU efficiency value is obtained which is evaluated. The results of this study show how to modify the Multiplier Model-CCR into the Envelopment Model-CCR. Then displays the efficient level DMU which is evaluated as a result of the weight each DMU gets from the results of processing the LINDO application. Illustrations of changes in input variables and output variables are displayed in the form of tables and figures before and after the changes. The modified DEA-CCR model can also complete DMU super efficiency, effectiveness and productivity.
