Abstract

The schedule for each course should be arranged such that the course taken by the same student or involving the same lecturer are not scheduled on the same day and time. This is to avoid conflicting schedules for students and lecturers. In the odd semester academic year 2021/2022, there were 23 courses scheduled at the study program of Mathematics, Universitas Jambi. The students in semesters 1 and 5 were divided into 2 classes, respectively, due to a large number of students in that semester. Therefore, the arrangement of the course schedule was getting more complicated. This research aimed to arrange the course schedule so that there is no clash by using the graph coloring approach. This research was classified as case study research and applied the descriptive method. The arrangement of the course schedule began with modeling the problem in the form of a graph and then using the Welch Powell algorithm to color the vertices in the graph. The graph consists of 36 vertices and 215 edges. By applying the Welch-Powell algorithm, the chromatic number obtained was 10, which means there are 10 optimum sessions or 10 minimum sessions of the course schedule in the odd semester in the Mathematics study program Universitas Jambi. Based on this result, the grouping of courses can be obtained that can be scheduled on the same day and at the same time.

Abstract

Kemiskinan salah satu penghambat dalam pembangunan, sehingga kemiskinan masuk dalam program yang harus diatasi. Pengentasan kemiskinan dapat dilakukan dengan melakukan berbagai program perbaikan ekonomi masyarakat. Sehingga dilakukanlah analisis faktor-faktor yang menyebabkan kemiskinan. Penyebab dari kejadian kemiskinan dikatakan sebagai variabel prediktor dan tingkat kemiskinan disebut sebagai variabel respon. Adanya hubungan pengaruh antara variabel respon dan variabel prediktor dinamakan dengan regresi. Kemudian penyebab dari tingkat kemiskinan ternyata tidak hanya dipengaruhi oleh variabel prediktor, tetapi lokasi dari daerah sangat mempengaruhi. Adanya keterhubungan antar lokasi ini dapat dianalisis dengan Geographically Weighted Regression (GWR). Hasil yang diperoleh yaitu variabel prediktor secara keseluruhan berpengaruh yaitu tidak ada ijazah SD, lulus SMP, lulus PT, upah minimum pendapatan, manfaat BPJS, besar konsumsi pangan dan papan, pendapatan per kapita. Jika dilihat dari nilai AIC dan RRS yang lebih kecil serta nilai  yang tinggi sebesar 95,95% maka model GWR dihasilkan lebih baik menganalisis tingkat kemiskinan di Provinsi Jambi.

Abstract

Covid-19 which has hit various countries in the world has become a scary thing for people to do activities outside the home. So that to carry out community activities, they must follow the rules of the health protocol that have been set, such as wearing masks, washing hands and keeping a distance. Covid-19 cases that occur can be spread through interactions between infected people. The interaction between communities is not only carried out in each region, but can be carried out between provinces within a region. The extent of interaction between people at this time can lead to the easy spread of Covid-19 cases. So that the number of COVID-19 cases can appear in several areas. The existence of a relationship between several predictor variables that affect the response variable in the form of count data can be referred to as Poisson regression. The dominant factors that caused the large number of Covid-19 sufferers on the island of Sumatra were the population, poverty level, income, regional temperature, compliance with wearing masks and compliance with maintaining distance.

Abstract

Lecturer is a profession that has the obligations of the Tridharma of Higher Education. Tridharma includes teaching, research and community service. Each tridharma element must be properly measured as the performance of a lecturer. Lecturer performance in research can be assessed from the quality of the output. The outputs of lecturer research activities are required to be published so that they can be known and become a public reference. Thus, published research results must be properly presented. Problems were found in analyzing the data by the lecturers of the Health Polytechnic of the Jambi Ministry of Health when carrying out the research. So far, data analysis has been limited to analysis of variance (ANOVA). The drawback in using analysis of variance alone in research is that errors will appear in drawing conclusions. Therefore, to overcome these problems, regression analysis training was held to improve the quality of lecturer research at the Jambi Ministry of Health Polytechnic as a form of dedication by lecturers from Jambi University. The activities carried out were in the form of workshops and practice of regression analysis for health cases using Minitab and SPSS software, besides that, interpretation of the results was also carried out. The community service activities carried out were carried out according to the plan, then this activity received a good response from the lecturers at the Jambi Health Polytechnic. This training activity also provides opportunities for communication and collaboration between lecturers from different fields and agencies. Keywords: Regression Analysis, Minitab, Community Service, SPSS
