Structural Equation Modeling (SEM) is a statistical analysis technique used to build and test statistical models in the form of causal models. Large-Scale Social Restrictions (PSBB) are government policies to break the chain of spreading the corona virus (Covid-19). This policy certainly has an impact on drivers of public transport services. This research shows that the passengers are very satisfied with the travel safety factor. Meanwhile, service factors and passenger public transport fares are in the satisfied category. Furthermore, the variable service quality (MP), the price of public transportation (H), and passenger safety (KP) have an influence on passenger satisfaction. Because the t-value is greater than 1.96 (for the real level of 5%). The influence of service quality, price and safety variables on passenger satisfaction is 78.1%, the remaining 21.9% is influenced by other variables outside the research.Keywords: covid-19, structural equation modeling, satisfaction.

The statistical method used to model the relationship between the response variable (Y) and one or more independent variables (X) is regression analysis. Linear regression equations are used to analyze the response variables in the form of continuous random variables and follow a normal distribution, however, many response variables are found that are not normally distributed and are not linear in parameters becausethe mortality rate for mothers and babies always increases from year to year. The number of maternal deaths that occurred in Maluku province is an example of data count. Poisson regression is a nonlinear regression analysis of the Poisson distribution which is generally used in analyzing discrete (count) data. The purpose of this study was to determine the factors that significantly affect maternal mortality in Maluku Province using Poisson Regression, The results of this study indicate that the factors that significantly influence the number of maternal deaths in Maluku Province are the number of health centers and medical personnel in each regency / district. City (X1), the percentage of female population with education that has completed at least SD per Regency / City (X2), the frequency coverage of K4 services for pregnant women in each Regency / City (X3), and the percentage of immunization coverage for pregnant women in each Regency / City (X4).Keywords: Maternal Mortality, Poisson Regression, Regression Analysis. AbstrakMetode statistika yang digunakan untuk memodelkan hubungan antara variabel respons (Y) dengan satu atau lebih variabel bebas (X) adalah analisis regresi. Persamaan regresi linear digunakan untuk menganalisis variabel respons yang berupa peubah acak kontinu dan mengikuti distribusi normal, namun banyak ditemukan variabel respons yang tidak berdistribusi normal dan tidak linear dalam parameter. Jumlah kematian ibu yang terjadi di provinsi Maluku merupakan salah satu contoh data count. Regresi Poisson merupakan analisis regresi nonlinear dari distribusi Poisson yang umumnya digunakan dalam menganalisis data diskrit (count). Tujuan dari penilitian ini adalah untuk mengetahui faktor-faktor yang signifikan mempengaruhi jumlah kematian ibu di Provinsi Maluku dengan menggunakan Regresi Poisson. Hasil penelitian ini menunjukan bahwa Faktor-faktor yang signifikan mempengaruhi jumlah kematian ibu di Provinsi Maluku adalah jumlah puskesmas dan tenaga medis tiap Kabupaten/Kota (X1), persentase penduduk perempuan dengan pendidikan yang ditamatkan minimal SD tiap Kabupaten/Kota (X2), cakupan frekuensi pelayanan K4 bagi ibu hamil tiap Kabupaten/Kota (X3), dan persentase cakupan imunisasi bagi ibu hamil tiap Kabupaten/Kota (X4).

The growth dynamics of various species are affected by various aspects. Harvesting interventions and the spread of disease in species are two important aspects that affect population dynamics and it can be studied. In this work, we consider a stage-structure Leslieâ€“Gower model with linear harvesting on the both prey and predator. Additionally, we also consider the infection aspect in the predator population. The population is divided into four subpopulations: immature prey, mature prey, susceptible predator, and infected predator. We analyze the existences and stabilities of feasible equilibrium points. Our results shown that the harvesting in prey and the disease in predator impacts the behavioral of system. The situation in the system is more complex due to disease in the predator population. Some numerical simulations are given to confirm our results.

This study aimed to predict the spread of the Covid-19 virus in Maluku Province using the fourth-order Runge-Kutta method. The mathematical model of the spread of the Covid-19 virus is a system of differential equations which includes Susceptible (S) variables, namely human subpopulations that are susceptible to Covid-19 virus infection, Infected (I), namely human subpopulations infected with the Covid-19 virus, Recovered (R) namely subpopulation of people who have recovered and Vaccination (V) namely a subpopulation that has been vaccinated and is immune to the Covid-19 virus, used as initial values. The values of are parameter values that are numerically solved by the fourth-order Runge-Kutta method performed for 24 literations with . Data were obtained from the Maluku Provincial Health Office from March 2022 - November 2022. Based on the data obtained, the average of the data is used as the initial value, where . The initial and parameter values were substituted into the numerical solution and simulated using Matlab. The rate value of each class for the next 24 months for the Susceptible (S), Infected (I), and Recovered (R) classes has decreased until it approaches zero equilibrium. It shows that the subpopulation of the three classes no longer exists, and the Vaccinated (V) class has increased significantly because almost all of the population has been vaccinated in the next 24 months. It shows that after an individual is vaccinated, he does not return to being vulnerable.
