Abstrak: Organization grows because of their corporate culture system can increase worker’s spirit so the workers performance will increase as well. PT Umas Jaya Agrotama (PT. UJA) as a company that focuses on tapioca production has potential to grow bigger, therefore it needs human resource management strategic through corporate culture which effectively affect the worker’s performance. The aims of this research are (1) to analyze corporate culture at PT UJA; (2) to analyze the worker’s perfomance at PT UJA; (3) to analyze the influence of corporate culture on worker’s performance at PT UJA. The research used multiple linear regression method. The result of the research based on worker’s response about the corporate culture and worker’s performance are impressive. The result of multiple linear regression shows that the corporate culture’s indicator has significantly effect together on the worker’s performance. Then the result of individual test shows that every corporate culture has significantly effect on the worker’s performance, except the creativity and courage culture.

Judul: Mathematical Model of Dengue Hemorrhagic Fever with Aedes albopictus Mosquitos as Vector
Abstrak: Dengue Hemorrhagic Fever (DHF) is an acute febrile illness caused by a dengue virus. This virus has four serotypes, i.e. Dengue I - IV. The dengue virus is transmitted by various species of Aedes mosquitoes. Mathematical model can be used to study the spread of the disease. The mathematical model discussed in this paper is SEIR model. The main vector of the disease is mosquito of the Aedes albopictus type. In the SEIR model, an analysis is performed to assess the stability of the equilibrium point and numerical simulations. There are two equilibrium points obtained. The first equilibrium point is a disease-free equilibrium (DFE), which is stable, given the basic reproductive number ℜ < 1. The second equilibrium point is called an endemic point, which stability is guaranteed if the value ℜ > 1. The numerical simulations show that increasing mosquitoes mortality rate makes the number of exposed susceptible humans decrease. Furthermore, increase in the average bite of infected mosquito will increase the number of exposed susceptible humans. For the mosquito population, increasing mosquitoes mortality rate will decrease the number of exposed susceptible mosquitoes. Finally, increase in the average bite of infected mosquito will increase the number of exposed susceptible mosquitoes.
