The Corona virus is a disease that threatens human population on earth in early 2020, the first infection began in China, is thought to be a virus that host in mammals and then able transmits into human body, this present paper will describe dynamic system of Covid-19, analyzing direction of the equilibrium, Disease Free Equilibrium (DFE) and Endem...

ABSTRAK Menggambar rumus persamaan fungsi merupakan sesuatu hal yang bisa menghubungkan antara dunia matematika dan seni, tetapi sebelum adanya program kalkulator grafik hal tersebut susah untuk dilakukan, dengan perkembangan teknologi saat ini terdapat suatu software atau program kalkulator grafik online yang bisa membantu dalam memvisualisasikan...

The research described a model formulation of COVID-19 using a dynamic system of Ordinary Differential Equation (ODE) which involved four population systems (susceptible, exposed, infectious, and recovered). Then, the research analyzed the direction of the equilibrium, Disease Free Equilibrium (DFE), and Endemic Equilibrium (EE). The treatment and...

Abstrak: Makalah ini mengemukakan pendekatan Norm Hankel Optimal (Optimal Norm Hankel Approximation (OHNA)) untuk mereduksi plant dari system linear yang tak berubah terhadap waktu. Dalam teori kendali, yang dimaksud dengan plant adalah obyek yang dikendalikan, kemudian akan diteliti sifat-sifat dari plant tereduksi. Selanjutnya akan dikaji juga ke...

Modeling a natural phenomenon or the action mechanism of a tool is often done in science and technology. Observations through computer simulations cost less relatively. In the research, a bullet control model moving towards the target was explored. The research aimed to try to simulate the trajectory of the bullet that could be controlled in huntin...

Hepatitis B infection that leads to chronic stage can be life threatening to human, for prevention it is necessary to conduct treatment and vaccination. Conducting treatment and vaccination are controls variables that will be applied to the dynamic modelling of Hepatitis B using Pontryagin Minimum Principle. The present paper will describe model fo...

Corona virus infection is lethal and life threatening to human life, for prevention it is necessary to carry out quarantined for a portion of susceptible, exposed, and infected population, this kind of quarantine is intended to reduce the spread of the corona virus. The optimal control that will be carried out in this research is conducting quarant...
