Abstract

The prevalence of anxiety disorders among university students is high, particularly during periods of high stress, such as when students are completing their final projects. This research aimed to investigate how self-confidence and anxiety levels relate among students working on their final projects at the Statistics Department at Universitas Negeri Gorontalo. Research was conducted on 86 students aged 21-26 years old using an online questionnaire. Self-confidence, self-efficacy, and social support were independent variables, while anxiety levels (mild, moderate, and severe) were dependent variables. Self-confidence was found to be significantly correlated with anxiety levels, while self-efficacy and social support were not significantly correlated. The result of ordinal logistic regression analysis indicated that students with high self-confidence were 0.13 times more likely to experience mild or moderate anxiety compared to those with moderate self-confidence. Those with high levels of self-confidence, however, are more likely to suffer from severe anxiety (26%) than those with moderate levels of self-confidence (4%). In certain academic situations, high self-confidence may not be a hindrance against anxiety. A more comprehensive understanding of anxiety will require further research considering additional factors that contribute to anxiety, factors that were not considered in this study.

Abstract

This study was aimed at discussing spatial regression to find out factors influencing the dengue fever vulnerability in Gorontalo city. The spatial regression method used in this study was the Spatial Autoregressive Model (SAR). The SAR model can provide additional information about the effect of the location of the village/village on the incidence of DBD in Gorontalo City. This study concluded that the number of population, number of poor population, educational facilities and the area elevation were factors influencing the dengue fever vulnerability in the city of Gorontalo.

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

A portfolio is a collection of financial assets in the stocks owned by a company or individual. An optimal portfolio is a selected portfolio that aligns with the investor's preferences, drawn from a set of efficient portfolios that have been formed. This research aims to create an optimal portfolio using the Multi-Objective Optimization method and the Nadir Compromise Programming (NCP) method. Additionally, Value at Risk (VaR) analysis is applied to determine the maximum risk an investor will bear for the portfolio. The data used consists of closing stock prices on the IDX30 Index from February 2022 to July 2023. The findings indicate that the optimization approach produces portfolios that align with investor risk-return preferences. The comparison of Multi-Objective Optimization and NCP methods provides insights into their effectiveness in portfolio selection. Furthermore, the VaR analysis helps investors understand potential risk levels, offering a comprehensive perspective on portfolio performance.

Abstract

This study is a development study that uses the 4-D model (define, design, develop, desiminate). Where the results of this study are learning media that can help students understand the material, especially on reflection material. The media developed is Canva media which has passed the validation stage of the readability test and the product cona test until Canva media can be said to be feasible as a learning media that can be distributed to students. The research location is SMP Negeri 1 Telaga Biru, where this media was developed there due to the lack of limited use of learning media and students tend to be taught using books in the absence of other learning resources. This attracted researchers to conduct research at the school. based on the results of the study, the Canva reflection media that has been developed gets a positive response from teachers and students with a teacher response of 100% and students 95%

Abstract

Salah satu konsep dalam bidang teori graf yang berkaitan erat dengan pewarnaan titik pelangi adalah bilangan terhubung titik pelangi. Sebuah graf G dikatakan terhubung titik pelangi jika terdapat setidaknya satu jalur yang menghubungkan titik-titik dengan warna yang berbeda. Konsep ini mengacu pada jumlah minimum warna yang dibutuhkan untuk mewarnai sebuah graf G sehingga graf tersebut terhubung dengan titik pelangi dan dilambangkan dengan rvc(G). Topik pewarnaan titik pelangi dapat dieksplorasi dalam berbagai bentuk pengembangan graf dengan memanfaatkan graf garis, graf tengah dan graf total. Graf garis L(G) adalah graf yang titik-titiknya merupakan sisi-sisi dari G, dan jika u, v ≥ E(G) maka uv ≥ E(L(G)) sedemikian sehingga u dan v saling berbagi titik di G. Graf tengah M(G), merupakan sebuah graf dengan himpunan titiknya merupakan gabungan antara kumpulan titik dan kumpulan sisi dari graf G. Sedangkan graf total T(G), yaitu graf yang titiknya didapatkan dari himpunan titim dan himpunan sisi dari graf G, dimana setiap titik V(G)saling terhubung. Pada penelitian ini, saya membahas bilangan terhubung titik pelangi yang terhubung pada graf garis, graf tengah dan graf total dari graf panci (Pnm) dengan m ≥ 6. Berdasarkan hasil yang diperoleh, didapatkan teorema bilangan terhubung titik pelangi pada graf garis dari graf panci rvc(L(Pn_m)), graf tengah dari graf panci rvc(M(Pn_m)), dan graf total dari graf panci rvc(T(Pn_m)).

Abstract

This study focuses on enhancing the competency of primary school teachers in integrating numeracy into learning activities across subjects. Numeracy literacy is a vital 21st-century skill essential for personal and professional decision-making. The training, conducted as part of a community service program, aimed to provide teachers with practical strategies for integrating numeracy into both mathematics and non-mathematics lessons. The methods involved workshops featuring lectures, discussions, and interactive group activities, emphasizing the development of teaching materials that connect numeracy to real-world applications. Evaluation through questionnaires revealed high participant satisfaction, with 87.5% rating the training as excellent. The findings underscore the significance of teacher competence in advancing student numeracy skills and highlight the need for continued professional development in this area

Abstract

Impulsive buying is a consumer behavior that makes purchases without prior planning. Impulsive buying is one of the consumer behavior phenomena that is increasingly widespread, especially on e‑commerce platforms such as Shopee during massive promotions on beautiful dates. Multiple Discriminant Analysis (MDA) is a method that has the advantage of classifying individuals into groups based on several predictor variables. The purpose of this study is to classify consumers into groups or categories based on their tendency to make impulse purchases on beautiful dates by analyzing the factors that influence them. The results of this study indicate that the beautiful date can affect the behavior of impulsive buying. The discriminant function model formed is able to distinguish categories of impulsive buying behavior with a good classification accuracy rate of 86.25% and the model shows that price is the most dominant or influential factor in distinguishing the category of impulsive buying of Shopee users on beautiful dates. This means that MDA Modeling is very helpful in classifying respondents into groups or categories based on the factors that influence them.
