Abstrak: Toksoplasmosis merupakan suatu penyakit pada manusia dan hewan yang disebabkan oleh parasit toksoplasma gondi. Penyebaran toksoplasmosis dapat dilakukan secara vertikal maupun horizontal. Penyebaran vertikal terjadi melalui ibu kepada anak sedangkan horizontal melalui lingkungan dan memakan makanan yang mentah. Lingkungan yang sanitasinya kurang memadai serta kebiasaan masyarakat memakan daging yang mentah mengakibatkan individu terinfeksi toksoplasmosis. Kebiasaan masyarakat Aceh dalam mengkonsumsi daging menjadi salah satu potensi terinfeksinya toksoplasmosis sehingga diperlukan sosialisasi dan kajian terkait pengendalian epidemi toksoplasmosis. Penelitian ini bertujuan untuk mengkonstruksi model matematika epidemi toksoplasmosis yang mengacu pada masyarakat di wilayah Lhokseumawe. Model matematika dikonstruksi kedalam bentuk persamaan diferensial tak linier kemudian dianalisis kestabilan dari masing-masing titik kesetimbangan serta dilakukan penentuan bilangan reproduksi dasar untuk melihat tingkat penyebaran penyakit. Simulasi model menunjukkan bahwa ketika tidak adanya penyebaran penyakit toksoplasmosis maka tidak ada individu yang terinfeksi sedangkan ketika terjadinya penyebaran toksoplasmosis mengakibatkan jumlah populasi yang terinfeksi meningkat dan kemudian menurun dikarenakan jumlah populasi terkontrol ikut meningkat sehingga penyakit toksoplasmosis dapat hilang dari lingkungan. Abstract: Toxoplasmosis is a disease in humans and animals which is caused by the parasite called toxoplasma gondi. The spread of toxoplasmosis can be done vertically or horizontally. Vertical spread occurs through mother and child, while horizontally through the environment and eating raw food. The inadequate sanitary environment and the community's habit of eating raw meat make the people infected by toxoplasmosis. The Acehnese habit in consuming meat is one of the potential infections of toxoplasmosis, so it is necessary to disseminate information and studies related to epidemic control of toxoplasmosis. This study aims to construct system differential non linear an epidemic mathematical model of toxoplasmosis that refers to people in Lhokseumawe area. The mathematical model constructed then analyzed the stability of each model equilibrium point and carried out the determination of basic reproduction numbers to see the extent of the spread of the disease. Simulation shows that when there is no spread of toxoplasmosis, no individual is infected. Whereas when the spread of toxoplasmosis happened, so the number of infected population increases and then decreases because the controlled population increases and toxoplasmosis can be disappeared from the environment.

This article aims to look at the dynamics of the toxoplasmosis epidemic with the effect of vaccination by increasing and decreasing the birth rate of infected with toxoplasmosis. The method used in this research is literature study and continued by using numerical simulation analysis. The research procedure used in this study is to simulate and analyze the parameters that affect the population. Some of the data used are secondary data on toxoplasmosis sufferers obtained from the Banda Aceh Health Office in 2018. From the numerical simulation results of the toxoplasmosis epidemic model with the vaccination effect, it was found that when the birth rate was infected with toxoplasmosis increased by at 5% then the number of individuals infected with toxoplasmosis, controlled individuals and the number of vaccinated individuals increases with the basic reproductive number Ro > 1. In this condition, there are no individuals who are susceptible to toxoplasmosis again so that vaccination for susceptible individuals can quickly overcome the spread of toxoplasmosis. Furthermore, the rate of births infected with toxoplasmosis decreases of 5% is obtained search population in the toxoplasmosis epidemic model has decreased with the basic reproduction number Ro <1. In this condition, the number of individuals in each population has decreased, resulting in the spread of toxoplasmosis disappeared from the population. So that this research can contribute to health science and the government in overcoming the toxoplasmosis epidemic.

The toxoplasmosis epidemic is an infectious disease caused by the parasitic Toxoplasma Gondii. This disease attacks the human immune system and other organs in the body, resulting in damage to tissues. The spread of the disease is carried out in various ways, one of them is eating foods that are less hygienic or not cooked properly, resulting in parasites remain active. Provision of controlled therapy is one solution in controlling the epidemic against suppression of the birth rate infected with toxoplasmosis. This study discusses the bifurcation analysis of a mathematical model for controlling the toxoplasmosis epidemic. Bifurcation analysis is carried out on the controlled rate and rate of birth control of toxoplasmosis. From the mathematical model of controlling the toxoplasmosis epidemic, stability and existence analysis are performed at each equilibrium point. Next, a function of two independent parameters is constructed which influences the spread of the disease, namely the controlled rate and the rate of infected births. Then, a bifurcation analysis of each region is obtained from each function of the two free parameters. From the bifurcation analysis, three regional conditions were obtained which showed the dynamics of the toxoplasmosis epidemic of two independent parameters with each interpretation of the bifurcation region.

Analisis sensitivitas model epidemi toksoplasmosis dengan efek vaksinasi dilakukan untuk mengetahui pengaruh perubahan nilai parameter terhadap nilai basic reproduction number (Ro). hasil penelitian menunjukkan bahwa terdapat dua titik ekuilibrium yaitu titik ekuilibrium bebas penyakit dan titik ekuilibrium endemi. Hasil analisis sensitivitas menunjukan bahwa laju kelahiran yang terinfeksi toksoplasmosis dan Laju individu terinfeksi toksoplasmosis yang tervaksinasi merupakan parameter yang sangat berpengaruh terhadap basic reproduction number. Kondisi tersebut diperoleh Ketika dilakukan peningkatan pada laju kelahiran yang terinfeksi toksoplasmosis mengakibatkan basic reproduction number meningkat, begitupun sebaliknya. Sementara itu, ketika dilakukan peningkatan pada Laju individu terinfeksi toksoplasmosis yang tervaksinasi mengakibatkan basic reproduction number menurun. Hasil ini mengimplikasikan bahwa tingkat pemberian vaksin toksoplasmosis bagi individu yang terinfeksi memiliki pengaruh yang sangat besar dalam pengendalian penyakit toksoplasmosis d Banda Aceh.
