Judul: Pengelolaan Lanskap Taman Kota Central Park Mall, Jakarta Barat
Abstrak: Central Park Mall is a mall in West Jakarta that has green garden area which is quite spacious. The shopping center was built with modern architecture and green building concept as one of the megaproject from P.T. Agung Podomoro Group, Tbk. located in Jalan Letnan Jenderal S. 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.

Sustainable management of the landscape ecopark may have implications for the Sentul City as an eco city. The purpose of this study is to analyze the implementation of the existing landscape, evaluation of landscape development, and make landscape management plan. With the research object Eco-Art Park Sentul City, this study used methods of surveys, questionnaires, interviews, and Analytical Hierarchy Process (AHP). Analysis of the implementation of the existing landscape Eco-Art Park Sentul City shows that the landscape has not fulfilled the criteria of ecological park. Basic concepts and landscape development has not led to the ecological park. Development landscape changes related to adjustments and the desire of the directors. In the management and maintenance of landscapes, operationally not lead to ecological park. In the preparation of the management plan, there are recommendations to restructure the management and the addition of landscape maintenance schedule.

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.
