Odd Harmonious Labeling on Pleated of the Dutch Windmill Graphs Firmansah, Fery; Yuwono, Muhammad Ridlo
CAUCHY Vol 4, No 4 (2017): CAUCHY
Publisher : Mathematics Department, Maulana Malik Ibrahim State Islamic University of Malang

A graph G(p,q) with p=|V(G)| vertices and q=|E(G)| edges. The graph G(p,q)Â is said to be odd harmonious if there exist an injection f: V(G)-{0,1,2,...,2q-1} such that the induced function f*: E(G)-{1,2,3,...,2q-1}Â defined by Â f*(uv)=f(u)+f(v) which is a bijection and f is said to be odd harmonious labeling of G(p,q). In this paper we prove that pleated of the Dutch windmill graphs C_4^(k)(r) with k=1 and r=1 are odd harmonious graph. Moreover, we also give odd harmonious labeling construction for the union pleated of the Dutch windmill graph Â C_4^(k)(r) union C_4^(k)(r)Â with k=1 and r=1.

Graf harmonis ganjil adalah graf yang memenuhi sifat pelabelan harmonis ganjil. Amalgamasi dua graf kincir angin belanda adalah graf yang dibentuk dari operasi amalgamasi dua graf kincir angin belanda dengan graf lintasan. Amalgamasi k graf kincir angin belanda adalah graf yang dibentuk dari operasi amalgamasi k graf kincir angin belanda dengan k-1 graf lintasan. Pada makalah ini penulis akan mengkonstruksi amalgamasi dua graf kincir angin belanda dan amalgamasi k graf kincir angin belanda, lebih lanjut penulis akan menunjukkan bahwa amalgamasi dua graf kincir angin belanda dan amalgamasi k graf kincir angin belanda adalah graf harmonis ganjil.

THE EFFECTIVENESS OF PROBLEM-BASED LEARNING WITH SOCIAL MEDIA ASSISTANCE TO IMPROVE STUDENTS’ UNDERSTANDING TOWARD STATISTICS Yuliana Yuliana; Fery Firmansah
Jurnal Infinity Vol 7, No 2 (2018): Volume 7 Number 2, INFINITY
Publisher : IKIP Siliwangi and I-MES

The objectives of the research are (1) to develop mathematics learning through Problem Based Learning (PBL) with social media assistance in improving students’ understanding toward statistics and (2) to find out the effectiveness of PBL with social media assistance. This research is a quasi-research with cluster random sampling. The cluster random sampling was employed to determine a control class and an experimental class. After treatment for each class, post-test was done. Then, the post-test data was analyzed through a T-test. The result is the mean score of post-test in experimental class was better than that in control class. It means PBL with social media assistance is more effective than the conventional model to teach statistics. The result was supported by a questionnaire that showed learning mathematics through PBL with social media assistance got a positive response from the students.

Publisher : Universitas Muhammadiyah Magelang

The purpose of this service is to optimize the use of ms. powerPoint for the development of innovative learning media. This training was held at SMP IT Ma'arif NU, Trucuk District, Klaten Regency, Central Java Province. This service was carried out by training methods on 1) making simple objects that can move automatically, 2) making countdowns, 3) making attractive template designs without downloading from the internet, and 4) making interactive practice questions. During the evaluation, participants were able to optimize Ms. PowerPoint for developing learning media.

Pelabelan Harmonis Ganjil pada Kelas Graf Baru Hasil Operasi Cartesian Product Fery Firmansah; Muhammad Ridlo Yuwono
Jurnal Matematika MANTIK Vol. 3 No. 2 (2017): Mathematics and Applied Mathematics
Publisher : Mathematics Department, Faculty of Science and Technology, UIN Sunan Ampel Surabaya

Graph class which has the characteristic of odd harmonious labeling is called as odd harmonious graph. Net graph is a graph which is gained by using operation Cartesian product of two line graphs. The construction of snake-net graph is inspired by the definition of snake graph replacing the round graph to net graph. In this paper, the study will show that snake-net graph fulfill the characteristic of odd harmonious graph in such a way snake-net graph is the odd harmonious graph. In the end of this paper, it is also shown that the union of snake-net graph is also called as the odd harmonious graph.

Graph labeling is one of the topics of graph theory that is growing very rapidly both in terms of theory and application. A graph that satisfies the labeling property of odd harmonious is called an odd harmonious graph. The method used in this research is qualitative research by developing a theory and a new class of graphs from odd harmonious graphs. In this research, a new graph class construction will be given in the form of an amalgamation of the generalized double quadrilateral windmill graph. Furthermore, it will be proved that the amalgamation of the generalized double quadrilateral windmill graph is an odd harmonious graph. So that the results of the research show that the amalgamation of the generalized double quadrilateral windmill graph is a new graph class of odd harmonious graphs.

Integer linear programming application in production results optimization using cutting plane method Fery Firmansah; Fitriana Wulandari

Publisher : Universitas Islam Negeri Raden Intan Lampung

Integer Linear Programming is a special form of linear programming which the decision variables are in integer form. Berkah Rasa is a home industry business in the form of Jenang Ayu and Jenang Krasikan processed food. The daily production that carried out by Berkah Rasa is based on the availability of raw materials and the number of requests. So far, Berkah Rasa has not had the right strategy in producing Jenang to get maximum profit. The purpose of this research is to apply integer linear programming to the optimization of Jenang Ayu and Jenang Krasikan production. The method used to solve this problem is the cutting plane method. The results of the research obtained is the optimal solution for Berkah Rasa, that is by producing 25 kg of Jenang Ayu and 22 kg of Jenang Krasikan every day. So that the benefits obtained by Berkah Rasa every day are IDR 727,000.00.

Odd Harmonious Labeling on Edge Amalgamation from Double Quadrilateral Graphs Fery Firmansah; Tasari Tasari

Publisher : Universitas Islam Negeri Raden Intan Lampung

A graph that has odd harmonious labeling properties is called an odd harmonious graph. The purpose of this research is to obtain a new class graphs construction which is a family of odd harmonious graphs. The research method used consisted of several stages, namely research preparation, research investigation and verifivation of research results. The results of this study, we will give a line amalgamation construction of n double quadrilateral graphs DQ, denoted by *DQ(n) with n= 1 and graph obtained by connecting between two graphs *DQ(n) with line graph L2, denoted by *(DQ(n),L2,DQ(n)). It has further been proven that *DQ(n) and *(DQ(n),L2,DQ(n)) have odd harmonious labeling properties, such that all of them are odd harmonious graphs.
