DETOUR ENERGY OF COMPLEMENT OF SUBGROUP GRAPH OF DIHEDRAL GROUP Abdussakir, Abdussakir
ZERO: Jurnal Sains, Matematika dan Terapan Vol 2, No 2 (2017): July - December
Publisher : UIN Sumatera Utara Medan

Study on the energy of a graph becomes a topic of great interest. One is the detour energy which is the sum of the absolute values of all eigenvalue of the detour matrix of a graph. Graphs obtained from a group also became a study that attracted the attention of many researchers. This article discusses the subgroup graph for several normal subgroups of dihedral groups. The discussion focused on the detour energy of complement of subgroup graph of dihedral group

DECISION SUPPORT SYSTEM FOR DETERMINING SCHOLARSHIP RECIPIENTS USING TOPSIS FMADM METHOD Husein, Ismail; Juliandri, Dedy

Granting scholarships to students aims to assist students in conducting lectures. Distribution of scholarships conducted by Muslim University Nusantara Al-Washliyah to help underprivileged or underachievers during their study The problem aims to choose some best alternative based on some attributes (criteria) used. In order to make decisions on fuzzy issues can be used Fuzzy Multiple AttributeDecision Making (FMADM). In this research modeling using Unified Modeling Language (UML) in FMADM with TOPSIS method and Weighted Product to select candidates of scholarship recipients.

APPLICATION OF FRACTAL CONCEPT IN MATERIAL BATIK DEVELOPMENT BASED ON WOLFRAMS MATHEMATICA Marom, Saiful
ZERO: Jurnal Sains, Matematika dan Terapan Vol 2, No 2 (2017): July - December

The geometry concept has been developed rapidly, one of them is about fractal geometry. In fractal geometry concept, it has been discussed about shapes which have fractal dimension characteristics. In fractal geometry concept, it would resulted in a look like irregular shape. But if it had been observed closer, it would found a regular shape. Self-similarity is a characteristic in fractal geometry when diferent magnifications was found. In fractal concept, a pattern would be obtained from a function itteration by an infinite repetition. One of fractal geometry application is in batik design fabrications. This idea based on equality dimension, that is both of them is in fractal dimension. In fractal geometry, it will result in a specific design by itterated function using Wolframs a program.

SIMULATION OF QUEUE PATIENT SERVICE Cipta, Hendra
ZERO: Jurnal Sains, Matematika dan Terapan Vol 1, No 1 (2017): January - June
Publisher : UIN Sumatera Utara Medan

Queue is one of the phenomena that occur in everyday activities experienced by everyone. As a result of this queue many people turn to other places to avoid a queue and get more leverage. The purpose of this study is to study the performance of the queue system by modeling a single queue simulation. From the analysis of distribution test calculation will be obtained by queuing model. The measured system parameters are expected average speed velocity, average service speed expectation, chance of busy period, probability of all patient service in system, expectation of queue length, expectation of waiting time in system, and waiting expectation in queue.Keywords: distribution test, queuing model, and system parameters

MATHEMATICAL ABILITY ANALYSIS BASED ON ASSIST SCALE WITH A DIFFERENT LEARNING APPROACH TO PREPARE A PROFESSIONAL TEACHER CANDIDATE IN DEALING WITH ASEAN ECONOMIC COMUNITY (AEC) Sihombing, Dame Ifa; Hutauruk, Agusmanto; Husein, Ismail
ZERO: Jurnal Sains, Matematika dan Terapan Vol 2, No 2 (2017): July - December
Publisher : UIN Sumatera Utara Medan

This paper aimed to basic mathematical skills based to the studying approach. To this subject pre detection is a need. One way ANOVA analyzing will show the significant of basic mathematical skill of students by giving different studying approach. Hence, there is correlation within basic mathematical skill to studying approach. Teachers should be able measure basic mathematical by designing model supporting understanding level, critical thinking ability made concept. The sample consisted of all the second semester of mathematical students by random sampling. Approaches and Study Skills Inventory for Students (ASSIST) is used to studying approach, Bayesian Information Criterion (BIC) is used to create group classification. Two Step Cluster Analysis Method divided into three approaches (Strategies, Surface, Deep)

UTILIZATION OF ZEOLITS FOR WATER FILING Dur, Sajaratud
ZERO: Jurnal Sains, Matematika dan Terapan Vol 3, No 1 (2018): January - June
Publisher : UIN Sumatera Utara Medan

This study aims to obtain zeolite powder from Sarulla natural zeolite as an adsorbent, particle size of zeolite powder, and water analysis before and after water purification. The benefit is to increase the benefits of zeolite to a higher economic value.The method used is the grinding mill method to smooth the zeolite chunks. Whereas the water purification process uses a screening process.The results of this study were zeolite produced at 200 mesh or 74 microns, and the purification was successfully carried out.The conclusion of this study is that zeolite powder obtained from Sarulla natural zeolite as an adsorbent, obtained zeolite particles namely 200 mesh or 74 microns, and the water purification process was successfully carried out.

MODEL OF SPREAD CONTENT DISEASE FOR ASSOCIATION OF VACCINE Jumiati, Ety; Husein, Ismail
ZERO: Jurnal Sains, Matematika dan Terapan Vol 4, No 2 (2018): July - Desember
Publisher : UIN Sumatera Utara Medan

Transmission of infectious diseases in epidemiological models is usually based on the assumption that populations in random mixing. However, in reality this assumption is not fulfilled, because each individual has a limited set of contacts that they can pass through infection; the ensemble of all such contacts forms a complex network. Knowledge of network structure allows a model to calculate the dynamics of an epidemic at a population scale from individual level infection behavior. This paper discusses mathematical models to illustrate the epidemic pattern of transmission of infectious diseases in dynamic networks based on compartment systems.

GRACEFUL LABEING AND RHO TOPI LABELING ON THE 8-BINTANG GRAPH WITH C3 FOR N ODD Amri, Zulfi; Harahap, Tua Halomoan; Irvan, Irvan
ZERO: Jurnal Sains, Matematika dan Terapan Vol 3, No 1 (2018): January - June
Publisher : UIN Sumatera Utara Medan

This paper we propose graceful labeling and labeling on a graph then referred to as 8-Bintang graph, the basic idea of formulation graceful labeling and labeling on an alfabet bintang graphs wih the question a stars graph . Then we constructing graceful labeling and labeling on the 8-Bintang graph with circle graph for odd. The results obtained are illustrated in the theorem that the 8-Bintang graph with for odd has the following graceful labeling with the proof.

FUZZY MULTIPLE ATTRIBUTE DECISION MAKING IN HOTEL SELECTION Aprilia, Rima
ZERO: Jurnal Sains, Matematika dan Terapan Vol 4, No 2 (2018): July - Desember
Publisher : UIN Sumatera Utara Medan

As the third largest city in Indonesia, Medan has become one of the cities visited by many tourists, so many hotels have sprung up, from just guest houses to star hotels with various facilities provided. In the selection of hotels to stay, Fuzzy Multiple Attribute Decision Making is expected to provide the best solution in these problems. So that when tourists come to Medan, they can choose the best hotel that suits their needs. The output of this study, the collection of relevant references to the formulation of the problem. The aim is to strengthen the problem and as a theoretical basis for conducting the study and also become the basis for designing decision support systems

DECISION SUPPORT SYSTEM FOR DETERMINING BEST HOMEROOM TEACHER WITH TOPSIS METHOD IN MIS NURUL HUDA PANTAI LABU Purba, Elisa; Vinsensia, Desi; Utami, Yulia
ZERO: Jurnal Sains, Matematika dan Terapan Vol 3, No 1 (2018): January - June
Publisher : UIN Sumatera Utara Medan

During this time the determination of the best homeroom teacher at MIS Nurul Huda Pantai Labu was still using a manual process , so the results were not optimal. In this study the decision support system was built to facilitate the school in determining the best homeroom teacher using the Topsis method. The criteria used are 5: attendance, organizational experience, data on student achievement, interaction with students, and final education. This system design application is expected to help the school principal in making decisions about determining the best homeroom teacher
