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

Nurse scheduling is one of the problems that often arise in hospital management systems. Head of ICU room and nurse to cooperate in making good nurse scheduling for the creation of optimal service. In this paper, we study a hospital nurse schedule design by considering the level of nurse education and the provision of holidays. Nurses with undergraduate education (S1) Nurses become leaders on every shift and are accompanied by nurses with diploma education (D3). The scheduling model in this study using the nonpreemptive goal programming method and LINGO 11.0 software. The preparation of the schedule of nurses assigned to this method can optimize the need for efficient nurses per shift based on education level. The data in the research was obtained by collecting administrative data at Aloei Saboe Gorontalo hospital. The data used are the published schedule by the head of the ICU room. In making a nurse schedule, there are limitations to consider such ashospital regulation. The results of the study obtained an optimal solution in the form of meeting all the desired obstacles. Computational results shows that nurse scheduling using the nonpreemptive goal programming method and LINGO 11.0 software better than the schedule created manually. Every shift is a maximum of one leader with an undergraduate education (S1) background and accompanied by a nurse with a diploma education (D3) background. Keywords: scheduling, goal programming, nonpreemptive goal programming.

Abstract

This study aims to know whether or not there is an influence between the learning outcomes of students who are taught using the TGT cooperative learning model and that of using direct learning in terms of student motivation. This is a quasi experimental study using Treatment By Level design which is carried out in class XI SMA in Wonosari in the even semester of the 2022/2023 academic year. The study samples are the students in class XI, totalling 71 students. The data are obtained from instruments in the form of   multiple choice and questionnaires. Each is used to test mathematics learning outcomes and student motivation. Data analysis uses a two-way analysis of variance and a    Scheffe test. The findings show that: 1) The learning outcomes of students who are taught using the TGT learning model are higher than that of using the direct learning model. This content evidenced results obtained Fcount = 12.701 and Ftable = 3.98, so Fcount  > Ftable  causes the (H1) to be accepted. 2) There is interaction influence between the learning model and students' motivation on students' mathematics learning outcomes. This content evidenced results obtained Fcount = 5.1913 and Ftable = 3.98, so Fcount > Ftable causes the (H1 ) to be accepted. 3) The learning outcomes of students with high motivation who are taught using the TGT learning model are higher than that of using direct learning model. This content evidenced results obtained Fcount = 16.472 and Ftable   = 3.74, so Fcount  >   Ftable  causes the (H1 ) to be accepted. 4) The learning outcomes of students with low motivation who are taught using the TGT learning model are lower than that of using direct learning model. This content evidenced results obtained Fcount = 1.420 and Ftable = 3.74, so Fcount < Ftable causes the (H0 ) to be accepted.
