Abstract

Penelitian ini membahas tentang model diskrit eko-epidemiologi. Model eko-epidemiologi adalah gabungan dari ilmu ekologi dan epidemiologi yang membahas tentang interaksi antara predator, prey rentan, dan prey terinfeksi menggunakan fungsi respon Holling tipe I dan pertumbuhan prey rentan mengunakan fungsi logistik untuk membatasi pertumbuhan yang berlebihan pada prey rentan.Model diskrit eko-epidemiologi diperoleh dengan mendiskritisasikan model eko-epidemiologi menggunakan metode Euler. Dari model diskrit tersebut diperoleh 5 titik kesetimbangan, yaitu titik kesetimbangan E0 dimana semua populasi mengalami kepunahan, titik kesetimbangan E1 ketika terjadi kepunahan pada populasi prey terinfeksi dan predator, titik kesetimbangan E2 ketika terjadi kepunahan pada populasi prey terinfeksi, titik kesetimbangan E3 ketika terjadi kepunahan pada populasi predator, dan titik kesetimbangan E4 ketika semua populasi hidup berdampingan. Berdasarkan hasil analisisnya, selalu tidak stabil, hal ini disebabkan oleh nilai eigen yang diperoleh pada persamaan linierisasi model di sekitar titik-titik ekuilibrium tersebut, nilai mutlaknya selalu besar satu. Untuk E1, E2, E3, dan E4 kestabilan titik-titik kesetimbanganditentukan oleh suatau syarat dan kondisi tertentu.

Abstract

The economic model which deals with the economic cycle is Goodwin's Model. It presents the relationship between the employment rate and wage shares. In this study, the modification model was made, taking into three types of workers, namely high, medium, and low-skilled workers. Studies of the model are conducted by determining the equilibrium point and its stability analysis. Furthermore, a numerical simulation is given to see which model satisfies the ideal of Goodwin‘s model cycle prediction by using Indonesian data from 2000 to 2020. In the end, an investigation into the effects of reducing the wage gap between the three types of workers was conducted. The results showed two equilibrium points, namely The Equilibrium Point without Employment Rate and The Wages Share (T1) and the Existence Equilibrium Point of Employment Rate and Wages Share (T2). T1 achieves a stable node condition when ScQd+pi+et while T2 reaches a stable center condition when ScQd+pi+et. The simulation showed Goodwin's model of high- and low-skilled workers produced the ideal of Goodwin model cycle predictions, whereas Goodwin's model of medium-skilled workers and the entire economy (capitalist) didn’t produce the ideal of Goodwin model cycle predictions. Eventually, the effects of reducing the wage gap make the economy unstable.

Abstract

Penelitian ini bertujuan untuk mencari bilangan terhubung titik pelangi. Misalkan G=(V(G),E(G)) adalah Graf Terhubung tak-trivial. Graf G dikatakan terhubung titik pelangi jika antara setiap dua titik pada suatu lintasan memiliki warna yang berbeda. Rainbow Vertex Connection pada graf G yang terhubung (Rvc(G) merupakan minimum warna yang dibutuhkan untuk membuat graf G terhubung titik pelangi. Pada penelitian ini membahas tentang bilangan terhubung titik pelangi (Rvc(G) pada Graf Bunga (Wm,Kn) dan Graf Oleander (Orn) . Berdasarkan hasil dari penelitian maka diperoleh rvc(Wm,Kn)=2 jika m=3 dan m=4 dan n>=3, rvc(Wm,Kn)=3 jika m=5. rvc(Orn)=diam-1 jika n=3,n=4 dan n=5, rvc(Orn)=diam-1 jika n=6

Abstract

This research is a descriptive study that aims to describe students' critical thinking abilities carried out by online learning. This research was conducted in class VIII SMP Negeri Widyakrama involving 23 students as research subjects. Data collection was obtained from validated essay test instruments. The test instrument was used to collect data on students' mathematical critical thinking abilities with indicators (a) problem identification (b) analysis, (c) synthesis, and (d) drawing conclusions. The results showed that students' critical thinking abilities implemented through online learning at Widyakrama State Middle School were in the medium category. This is shown based on the classification of critical thinking abilities of 23 respondents. There are only 5 students who are in the high category, 14 students are in the medium category, and 4 other students are in a low category.

Abstract

This research deals with applying the Dijkstra algorithm and Welch-Powell algorithm to on-campus bus transportation problems. This research aims to determine the optimal solution of campus bus transportation routes in the shortest routes and schedules. In determining the fastest way, each intersection represented as a node, and the path described as the sides. The shortest path obtained V1 - V2 - V5 - V8 - V9 - V10 - V13 - V16. In determining the optimal schedule, the number of buses represents the vertices, and the time expresses the side that connects each node. The optimal program of the bus starts from 06.30 am to 5.00 pm. Every bus gets four sessions of departure and four sessions return with travel time each session is 60 minutes.

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.
