Abstract

Graf G = (V, E), where V is the set of points and E is the set of sides. Interesting application of a graph, one of which is graph coloring (graph coloring). There are three kinds of coloring that are point coloring, edge coloring, and region coloring. In this paper will be studied dye staining. Point coloring is to color the dots of a graph so that no two neighboring dots have the same color. The minimum number of colors that can be used to color graph is expressed by chromatic numbers. Currently a lot of applications from graph coloring, one of which is the storage of chemicals. In the storage of chemicals required a good arrangement, this is due to the influence of chemicals with each other if stored simultaneously.The main focus of this paper is to determine the chromatic number in graph o and the application scheme of dye graph coloring.Keywords: graph coloring, point coloring, edge coloring and region coloring

Abstract

One of the theories developed in graph theory is the dominating set. Dominating set is a concept of determining the minimum point on the graph with the provision of a point as dominating set to reach the point that is around it. The smallest cardinality of the dominating set is called the domination number denoted by (G). Given graph G with point V and E side, let D be a subset of V. If each point of VD is adjacent at least one point from D, then D is said dominating set in graph G. Currently a lot of applications from dominating set, one of which is placement of product sales branches. The product used is " pie susu dhian", pie susu is one of the typical Balinese foods that many Bai people and tourists enjoy, so it requires sales outlets in many shops and spread evenly so that tourists can find this pie susu in various parts of Bali , however, it is necessary to minimize the production and placement of pie susu branches so that they can be sold well. In the research focused application Placement of Sales Branches Of “Pie Susu Dhian” In Bali In Dominating Sets Application Keywords: dominating set, pie susu dhian

Abstract

 One of the theories developed in graph theory is the dominating set. Dominating set is a concept of determining the minimum point on the graph with the provision of a point as dominating set to reach the point that is around it. The smallest cardinality of the dominating set is called the domination number denoted by (G). Given graph G with point V and E side, let D be a subset of V. If each point of VD is adjacent at least one point from D, then D is said dominating set in graph G. Currently a lot of applications from dominating set, one of which is Minimizing the Construction of Lakes at River Meeting Points to Reduce Floods in Jakarta. In this study a river meeting will be rebuilt to select floods in Jakarta. Flooding is a natural disaster which is currently often in Indonesia. Especially in Jakarta. Jakarta is one of the risk areas for flooding in Indonesia and floods that always occur suddenly There are so many ways to reduce them, but that doesn't work. One of the causes of flooding in Jakarta is the overflow of river air. When a patient appears suddenly several rivers that have large currents, air flow will collide at the meeting point. When the river flows, the air will overflow large enough. Therefore, it is important to develop a lake at the river meeting point but it is necessary to make the lake as minimal as possible and also to be efficient. The research application dominates the set of lake developments in each river meeting point in the city. Keywords: dominating set, river, flood

Abstract

          Polyalphabetic cipher cryptosystem is the study of mathematical techniques that related to aspects of information security such as confidentiality, data integrity, authentication and authentication of data origin. With the internet, long distance communication can be done quickly and cheaply. However, the internet is not very secure because it is a public communication medium that can be used by anyone so it is very vulnerable to information tapping. Cryptography has been widely used in life for example banking atm ATMs, account numbers sacrificed, sending secret military messages. By applying polyalphabetic cipher cryptosystems, pins, account numbers and secret messages sent will be more secure and the information will not be easily known. Keywords: polyalphabetic cipher cryptosystem, banking, pin

Abstract

Ketergantungan masyarakat dengan penggunaan plastik menimbulkan masalah yang berkelanjutan terkait pengelolahannya. Paradigma yang terbangun di masyarkat khususnya di desa Mlokorejo yaitu sampah plastik dikelola dengan di bakar (Renfile) atau di kubur di dalam tanah. Padahal jika sampah di bakar akan mengakibatkan pencemaran udara dan dapat mengganggu kesehatan. Dan ketika di sampah plastik di kubur akan mempengaruhi unsur hara yang ada di dalam tanah. Dengan tata kelola yang salah atau belum sesuai maka akan menimbulkan masalah baru, maka dari itu kami menawarkan pengelolahan sampah plastik dengan menggunakan teknik pirolisis yang dapat mengkonversi plastik menjadi minyak. Dengan melakukan sosialisasi dan pelatihan pengelolahan sampah plastik dengan teknik pirolisis ini kami bertujuan dapat memberikan dampak positif terhadap desa Mlokorejo dan semoga pengelolahan sampah plastik pirolisis ini dapat di realisasikan dengan baik oleh pihak pemerintahan desa Mlokorejo.
