Parman Kav. 28 Jakarta 11470. The concept of development is very suitable as a place of internship activities to learn city park management and its implementation as a garden-based environment. The purpose of this internship is studying and analyzing aspects of the maintenance and management of the park, analyzing the desires of the users, and arranging the management strategies of Central Park Mall. Required data is on the activities of apprentices include physical aspects, social aspect, administration aspect, maintenance and management of park aspect. Analysis of data used the descriptive analysis, user analysis, and SWOT analysis. Based on result of the SWOT analysis, there are eight points strategies for management of Central Park Mall proposed to systems management on behalf of the manager in the future.

Thus, it will produce a landscape management strategy for TMR. Analysis of data is performed by using the descriptive analysis, visitor comfort analysis, and SWOT analysis. The results of SWOT analysis found that there are nine point of strategies for landscape management of TMR. TMR has some shortcomings in its management. TMR needs more professional management with support from various parties. TMR is under the responsibility of the Dinas Kelautan dan Pertanian of DKI Jakarta, so that TMR needs more attention from the Government of DKI Jakarta

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.
