Abstract

River has strategic role as one of the natural resources that supports peoples lives. Ciliwung has the most widespread impact during the rainy season because it flows through the center of the city of Jakarta and across many villages, dense housing and slums. This paper aims to formulate a concept for managing a slum neighborhood on the banks or Ciliwung watershed. This concept is supported by the main concept of the Green Water Front. Based on the results of our analysis, it is known that the low citizens living in the area Ciliwung River in maintaining the environment. To increase awareness of citizens in maintaining the environment, we carry a concept of Green Water Front, which is the core of this concept will change as the river behind the house into the river as the front of the house. So the river will be a point of interest. On this concept there will be a bridge crossing over the river which we call the bridge "Rhombus". The concept of Green Water Front will increase the interaction between people separated the river because of its function as well as bridges. The public rooms are located in the middle of the Green Water Front can serve as a plaza, childrens playground, or farming. So that this concept can be implemented properly, it must be required cooperation from various parties including students and university, government, and communities around the watersheds that are subject to the application of this concept.Keywords: Green water front, Ciliwung river, seedy neighborhood

Abstract

This paper presents a new variant of smart adaptive algorithm of Maximum Power Point Tracking (MPPT) in the photovoltaic (PV) system. The algorithm was adopted from Modified Perturb and Observe (MP&O). The smart adaptive MPPT is used to search Maximum Power Point (MPP) of the PV system under various irradiance changes. This algorithm incorporates information of current change (ΔI), maximum operating point margin and dynamic perturbation step to prevent MPPT diverging away from the MPP and minimize the steady state oscillation. The smart adaptive MPPT algorithm performance is compared with the dI-P&O and conventional P&O to prove its effectiveness. The comparison is performed under the various gradient of irradiance change. It was found that, for all the tests, the smart adaptive algorithm scheme improve the tracking efficiency under various gradients of irradiance changes and increase the efficiency of extraction power from PV system.
