Moreover, the entertainment center and residential area such as hotels and apartment buildings began to grow rapidly, leaving limited open space area and green areas. It takes a strategy in the utilization efficiency of construction building and effectiveness for a variety of needs in an area that is well integrated. Mixed-use development is a strategy that blends a combination of residential, commercial, cultural, institutional, or industrial uses, where those functions are physically and functionally integrated, and that provides pedestrian connections. The concept of mixed-use has been widely applied in many big city in America and Europe. Mixed-use nowadays began to developed in Jakarta, especially in residential complex area. The benefits of mixed-use development include: reduced distances between housing, workplaces, retail businesses, and other amenities and destinations, walkable, bike-able neighborhoods, increased accessibility via transit, both resulting in reduced transportation costs, more compact development, land-use synergy stronger neighborhood character, sense of place etc. Oemardi_zain (OZ) is one of the landscape consultant that based on landscape planning and designing in Indonesia.

Judul: Dynamical System of Hepatitis B in Three Groups with Vaccination
Abstrak: The aim of this study is to modify the hepatitis B transmission model in three age groups involving vaccination from the model conducted by Zhoe and Zhang.The method used is to analyze the stability of the fixed point and its basic reproduction number (R_0). Performed stability analysis and numerical simulation to see population dynamics. Next, a sensitivity analysis of the parameters was carried out to see its effect on R_0. From the analysis obtained two fixed points, namely non-endemic and endemic fixed points. Non-endemic fixed points are locally asymptotically stable if R_0 <1 Meanwhile, the endemic fixed point is locally asymptotically stable if R_0 > 1. Hepatitis vaccination affects the number of susceptible population, because the more successful the vaccination, the smaller the number of susceptible populations so that the smaller the population will be infected.
