Abstract

Logistics distribution in disaster-affected areas includes the delivery of relief goods (food, medicine, and clothing) using three types of vehicles with different carrying capacities for each vehicle. In distributing relief goods, unfulfilled requests can occur in disaster-affected areas. This problem can be modeled in the form of integer linear programming because there is a variable that must be an integer value to minimize unfulfilled demand for all types of relief goods at each point of demand. The branch and bound method can solve this problem's integer linear programming model. The next model is simulated using the LINGO 11.0 programming language. The simulation results show that the system can be considered feasible to use. Thus, the vehicle allocation is also obtained in each period with distribution costs from the point of supply to the point of demand. This distribution process lasts for four periods by showing a change in the number of unfulfilled requests. In the last period, there was no more unfulfilled demand for aid to obtain optimal results.

Abstract

Nile Tilapia and Mozambique Tilapia fish are different, but from the same genus, Oreochromis, these two fish are closely related and have a similar appearance. Therefore, many buyers often find it difficult to distinguish them. This research employs one method in machine learning that is always use to classify image, called Backpropagation in Artificial Neural Network. There were two stages in this study, first was feature extraction using convolution. Second was the learning process using the backpropagation algorithm. Before classification, the image data were prepared by cropping to focus on the classified object. Then from the 254 images, they were divided into three groups, 140 image were for training data, 60 images were for validation data, and 54 were for testing data. The result conluded that the success rate and accuracy reached 74,07% from the total data. To conclude, this method had successfully applied.

Abstract

Petri net is one model representing transitions and places connected by arrows. Max Plus Algebra is an algebraic structure in which all sets of real numbers  are equipped with max (maximum) and (addition). This research created a Petri net model of the customer service system for Bank BRI and a Max Plus Algebra model related to time to minimize service time at Bank BRI. The result is periodic time or characteristic values and vector characteristics where the values and are . The value of this vector's characteristics becomes a periodic time, which only takes 2 days 3 hours during working hours to disburse money after the client's arrival.

Abstract

This research is motivated by the low motivation to learn mathematics in mathematics in class VII-3 of SMP Negeri 1 Telaga Jaya. This study aims to increase students' motivation to learn mathematics through the use of cooperative learning models of the Teams Games Tournament (TGT) type. This type of research is classroom action research (PTK). Kemmis and Mc Design. Taggart was used for this research. This study used data collection techniques, namely observation and questionnaires. Teacher observation sheets, student observation sheets, and learning motivation questionnaires were used to view the data. Plan, report, observe, and think about what you have learned are all part of the research process. The research was conducted in two parts. The results showed that teacher activity in learning increased by 88.88%, and student activity increased by 93.75%. Student motivation also increased, with 10 students getting a score of 34.38% in the "very high" category and 65.52% in the "high" category. Indicators show that each student's learning motivation experienced a high increase, with a score of 34.38% in the "very high" category and 65.52% in the "high" category.

Abstract

Structural Equation Modeling (SEM) is a multivariate statistical method. in addition, SEM is a method that is able to disclose the simultaneous correlation between indicator variables (which are directly observed) and latent variables (which are not directly observed). Information and communication technology developments facilitate the growth of the digital economy. One form of implementing technology and information in the growth of the digital economy is conducting non-cash transaction. Furthermore, digital financial service are financial service that use digital technology through third paties, namely without intermediaries from banks and the general public. Technological development change business activities in financial service, especially in the digital world. The use of a QR (Quick Response) code payment system is a system that is currently popular. On January 1, 2020, Bank Indonesia officially released a standart for using the Indonesian QR code called Quick Response Code Indonesian Standard (QRIS). Thus, this research aimed to determine the factors affecting MSME customers’ interest in using QRIS as a payment method. This research employed 97 respondents’ responses obtained from distributing questionnaires to MSME (Micro, Small, and medium Enterprises) in Gorontalo City, in which the respondents were the customer who often used QRIS as the payment method. The finding indicated that public understanding and convenience affected customers’ interest in using QRIS as a payment mtehod. In comparison, the benefits and obstacles did not significantly affect customers’ interest in using QRIS as a payment method.

Abstract

Edge coloring of a graph is considered rainbow connected if the graph is connected and a rainbow path exists for every pair of points. The rainbow connection number of a graph, denoted as , represents the smallest number of colors required to make the graph is rainbow connected. This study examines the rainbow connection number of the middle graph of a caterpillar graph. The middle graph is a modified result of a graph , denoted as . It is described as a graph constructed from the intersection of a set of points and edges. The set of points in the middle graph consists of the combination of points and edges of the graph . Two points are considered adjacent if only they are connected in , or if one point corresponds to a point and the other corresponds to an edge adjacent to it. A caterpillar graph denoted by is a tree that will be a path if all the leaf points are deleted. The results of this research show the rainbow-connected number theorem for the middle graph of the caterpillar graph for .

Abstract

Let G be a simple and finite graph. Rainbow connection and total rainbow connection c are set c : G → {1,2,. . . , k} where k is the minimal color on graph G. A rainbow connection number(rc) is a pattern by giving different colors to the connection edges (E(G)) so that a rainbow path is formed. The total rainbow connection number (trc) is a payment pattern by giving color to vertices (V(G)) and edges (E(G)) in graph G so that a total rainbow path is formed. This article discusses rainbow connection numbers (rc) and total rainbow connection numbers (trc) in the corona graph of book graph (Bn) and pencil graph (Pcm). The results obtained are rc(Bn ⨀ Pcm) = 2n+3 and trc(Bn ⨀ Pcm) = 4n+5, 3 ≤ n ≤ 5.
