This is done so that<br>students can solve math problems. This study aims to determine whether there is an influence of the<br>superitem learning model on mathematics learning outcomes in class V classroom materials at<br>Tiranus Private Elementary School. This study used a quasi-experimental research method with a<br>one group pretest-posttest design consisting of one predetermined group. The population in this study<br>were fifth grade students at SDS Tiranus, Duren Sawit District, for the 2022/2023 school year with a<br>total sample of 19 people. The results showed that the use of the superitem learning model had a<br>positive and significant effect on mathematics learning outcomes in class V class V Tiranus Private<br>Elementary School.</p> Yerikho Zihkri Zihkri Copyright (c) https://journal.unhas.ac.id/index.php/jmsk/article/view/25229 EFFECTIVENESS OF VACCINATION IN A MODEL OF THE SPREAD OF COVID-19 IN JEMBER DISTRICT https://journal.unhas.ac.id/index.php/jmsk/article/view/25216 <p>This paper discusses the model of the spread of Covid-19 using vaccines as a prevention of the spread of Covid-19 in Jember Regency. This model divides compartments into 6 compartments namely susceptible (susceptible population), exposed (exposed population), infected (infected population), recovered (cured population), vaccinated 1 (vaccine population 1), and vaccinated 2 (vaccinated population 2 doses). The SEIRV1V2 Covid-19 transmission model has a reproduction number of 0.453877 which was searched using NGM, which means that Covid-19 is slowly disappearing from Jember Regency over time. By varying the parameter values ​​using Maple 18 to test the effectiveness of vaccination in preventing the spread of Covid-19. It was found that the vaccine was effective in preventing Covid-19 with the infected and exposed population decreasing and the disease-resistant population increasing</p> <p><strong>Keywords</strong>: Vaccine effectiveness, SEIRV1V2 model, New Generation Matrices</p> Riska Winata Copyright (c) https://journal.unhas.ac.id/index.php/jmsk/article/view/25216 Differential Graph On The Result of Corona Operation Between Path Graph and Complete Graph https://journal.unhas.ac.id/index.php/jmsk/article/view/25140 <p>Let &nbsp;be an arbitrary graph.

In 2020, Indonesia has the largest GMV (Gross Merchandise Value) value for online food delivery services in Southeast Asia with a GMV value of $3.7 billion, following other countries. There are several reasons why people buy food online, including saving time, there are several attractive and practical offers and many choices. Based on the explanation above, this research was conducted which aims to analyze the variables that influence consumer satisfaction using online food purchasing services using multiple linear regression methods. The results of this study are expected to support the performance of culinary businesses in general and UKM culinary businesses in particular by increasing and maintaining variables that greatly influence the quality of these services so that consumers remain loyal in making online purchases.</p> <p>&nbsp;</p> <p>&nbsp;</p> Fuji Rahayu Wilujeng Copyright (c) https://journal.unhas.ac.id/index.php/jmsk/article/view/25096 The Numerical Completion of the Penyelesaian Numerik Model Predator-Prey Dengan Dua Predator dan Satu Prey Terinfeksi https://journal.unhas.ac.id/index.php/jmsk/article/view/25094 <p><strong><em>Abstract</em></strong></p> <p>The article discussed numerical completion of the predatory prey model with two predators and one prey infected. The model is divided into vulnerable prey, infected prey, first predator and second predator. The model is resolved using multistep numerical method, the Adams bashforth moulton method, and the Milne method, further simulated with R2015b MATLAB application. The program simulation conducted with several of varying rate parameters. Analysis of the simulations showed no significant difference, but the Milne method speed had a faster computing than Adams Bashforth Moulton method.</p> <p><strong>Keywords: </strong>Model of predator-prey, Adams bashforth moulton method, Milne method.</p> Sinta Munawaroh Copyright (c) https://journal.unhas.ac.id/index.php/jmsk/article/view/25094 Determinan Efisiensi Pengeluaran Pemerintah Sektor Kesehatan di Provinsi Aceh Tahun 2015-2019 https://journal.unhas.ac.id/index.php/jmsk/article/view/25083 <p>Salah satu indikator yang mencerminkan keberhasilan pembangunan ekonomi adalah pembangunan manusia. Faktor kesehatan memiliki peran penting dalam penciptaan sumber daya manusia yang berkualitas. Semakin besar tingkat pengeluaran pemerintah sektor kesehatan akan memberikan peningkatan terhadap derajat kesehatan. Pada nyatanya capaian pembangunan kesehatan yang tinggi dalam masyarakat tidak serta merta tercipta dari tingginya tingkat pengeluaran kesehatan. Perbedaan dan variasi pembangunan sumber daya manusia terjadi karena pengaruh efisiensi penggunaan pengeluaran pemerintah. Studi ini bertujuan untuk mengidentifikasi tingkat efisiensi pengeluaran pemerintah sektor kesehatan tiap kabupaten/kota di Provinsi Aceh tahun 2015-2019 dan&nbsp;mengkaji determinannya. Metode yang digunakan untuk mengukur efisiensi adalah Data Envelopment Analysis (DEA) dan regresi tobit data panel untuk mencari determinannya. Hasil analisis menunjukkan tiap kabupaten/kota didominasi pengeluaran pemerintah sektor kesehatan yang relatif tidak efisien serta variabel belanja pegawai, tingkat kemiskinan, dan ukuran pengeluaran pemerintah secara statistik berpengaruh signifikan negatif terhadap efisiensi pengeluaran pemerintah sektor kesehatan.&nbsp;Dengan demikian, pemerintah hendaknya memprioritaskan pertumbuhan ekonomi dengan pemerataan pembangunan infrastuktur, meningkatkan perbaikan pengelolaan penggunaan anggaran mengurangi pengalokasian belanja pegawai, dan mengurangi tingkat kemiskinan dengan meningkatkan kualitas serta pemerataan akses layanan pendidikan dan kesehatan, membentuk program penyediaan hunian yang layak pakai, pemenuhan fasilitas sanitasi, serta penyediaan air bersih.</p> ihza mahendra Copyright (c) https://journal.unhas.ac.id/index.php/jmsk/article/view/25083 Comparison Of Kruskal Algorithm And Floyd-Warshall Algorithm In Electrical Network Optimization https://journal.unhas.ac.id/index.php/jmsk/article/view/24986 <p>Graph theory is a long-known subject that has many applications today. Graph theory is widely applied in various scientific fields, one of which is optimizing the PLN electricity network. This article discusses the optimization of the electricity network using the Kruskal Algorithm and the Floyd-Warshall Algorithm in the Kota Tengah sub-district, Gorontalo City. This study aims to look at the comparison of the Kruskal Algorithm and the Floyd-Warshall Algorithm in an electrical network system that can minimize the use of electric cables. The initial steps taken in completing this research were observing the problem, formulating the problem, then proceeding with data collection, data analysis, and problem solving and drawing conclusions. The results obtained after applying Kruskal's algorithm, the number of sides on a power pole is 83 sides with the length of the installed power cable being 19,773 meters long. While the results obtained when the Floyd-Warshall Algorithm is applied, the shortest path is 3444 paths and the cable network length is 19,773 meters. Kruskal's algorithm and Floyd-warshall's algorithm are both effective, because they get the same results, namely 83 sides and a cable length of 19,773 meters. Initially, in the Kota Tengah sub-district, the total side results were 93 with a total length of the electricity network cable, which was 24,618 meters. After applying these two methods, the use of the electricity network is more optimal compared to not using the two methods.</p> Sri Mahmud Copyright (c) https://journal.unhas.ac.id/index.php/jmsk/article/view/24986
