Abstract

Passenger waiting time is the time required by passengers starting from the stops until getting transport. The purpose of this research is to get the model of waiting time passengers on the freight line in the Palu city. The first step is the preparation of directed graphs based on the existring routes, then calculate the mileage and travel time using synchronization rules and power algorithm with initial vector 𝑥 = 0 obtained the value 𝑝 = 2, 𝑞 = 1 and 𝑐 = 102by using the appplication rock Scilab 5.5.2 and Map-Plus Toolbox obtained eigenvalues as the departure period of 102 and eigenvektor as the initial departure time.Keywords : Eigenvalues, Eigenvectors, Max-Plus Algebra, Waiting Time.

Abstract

ABSTRACT Meatballs are foods made from meat, shrimp, fish chopped and crushed together with starch and egg white, usually formed roundly. Meatballs have health benefits for the human body because of the content contained in animal protein, vitamins and fat. However, in the manufacture of meatballs for the benefit of many, sellers often use the wrong way by using borax chemicals on meatballs. Therefore, this study aims to build a design tool in the form of borax detection on meatballs based on android. The tool works by processing the input data obtained from a color sensor coupled with an LED (Light Emitting Diode) to the microcontroller on Arduino Uno R3. The data is processed by implementing the Mamdani fuzzy logic method as a decision to state the output output of borax detector on meatballs. Furthermore, the output output displayed on the device using a sample of 12 meatballs obtained tool accuracy of 75%. Keywords : Boraks, Color Sensor, Fuzzy Logic, Microcontroller, Meatball.

Abstract

Let be a simple graph. An edge covering of is a family of subgraphs such that each edge of graph belongs to at least one of the , subgraphs. If each is isomorphic with the given graph , then it is said that contains a covering. The graph G contains a covering and the bijectif function is said an the magic labeling of a graph G if for each subgraph of is isomorphic to , so that is a constant. It is said that the graph G has a super magic if in this case, the graph G which can be labeled with magic is called the covering graph magic. A star graph with n points is a graph with points and sides, where point is degree and the other point has degree denoted by . This study aims to determine the presence of covering labeling for the super-magic star on the star graph. The research methodology is literature study. The results show that the star graph for has magic covering labeling with magic constants for all covering is and the super-magic covering labeling with magic constants for all covering is .

Abstract

Batik merupakan salah satu warisan seni budaya bangsa Indonesia yang ada untuk terus dipertahankan dan dikembangkan. Upaya ini dilakukan dengan memperbanyak motif--motif baru yang salah satunya dengan mengekplorasi keunikan alam yang ada. Alam Sulawesi Tengah dengan keunikan flora-nya, yaitu bunga anggrek dengan nama Latin Calanthe Triplicata merupakan jenis tanaman endemic yang diekplorasi guna mendapatkan motif baru untuk menambah keragaman Batik di Indonesia. Etnomatematika merupakan salah satu cabang ilmu matematika untuk membahas hubungan antara matematika dan budaya yang dapat digunakan untuk membentuk pola Batik, khususnya bentuk fraktal. Bentuk fraktal adalah suatu objek yang tampak memiliki kemiripan diri yang simetris satu sama lain jika dilihat pada skala tertentu dan merupakan bagian terkecil dari keseluruhan struktur objek. Di dalam penelitian ini dilakukan pembuatan bentuk fraktal dengan mentransformasi tanaman anggrek sebagai branding unik untuk motif batik Sulawesi Tengah. Adapun hasil yang diperoleh berupa metif-motif baru yang unik, menarik dan elegan yang kita sebut dengan motif Sambuang, Rekang, Kecrek dan Angkan.
