Abstract

This paper presents a successful effort in emulating the Indonesian national electronic ID smart cards using Java Card. The aim is to provide theopportunity for other smart card products to contribute in the national electronic ID program. The life cycle status, the file system concept, commands and security procedures implemented in the Indonesian national electronic ID were reproduced and emulated ina Java Card applet. In the first stage, the emulator applet was tested using some test scenarios developed during the implementation phase. Later on, the emulator applet was tested in the real system under supervisioned by Direktorat Jenderal Kependudukan dan Pencatatan Sipil in order tomeasure its reliability as well as to determine that its behaviour is identical with the Indonesian national electronic ID. The results confirmed that this approach was fruitful.

Abstract

This paper proposes a method for controlling groundwater level in order to maintain a certain desired height by using a simple fuzzy control system. The control signal is determined by evaluating the state of water surface height deviatioh from the desired height on a 4 quadrant phase plane. The control signal is then used to determine the number of drainage or irrigation pumps, which must be operated. Simulation using actual datafrom the jield shows that the proposed method is very effective to maintain the desired height of water surface. This method is very simple, therefore it can be easily implemented using a personal computer or a microcontrol/er, or up-loaded to a P LC (Programmable Logic Controller).
