Along with the times, recently there have been found tool to facilitate human’s work. Electronics is one of technology to facilitate human’s work. One of human desire is being safe, so that people think to make a tool which can monitor the surrounding condition without being monitored with people’s own eyes. Public awareness of the underground water channels currently felt still very little so frequent floods. To avoid the flood disaster monitoring needs to be done to underground water channels.This tool is controlled via a web browser. for the components used in this monitoring system is the Raspberry Pi technology where the system can take pictures in real time with the help of Logitech C170 webcam camera. web browser and Raspberry Pi make everyone can control the devices around with using smartphone, laptop, computer and ipad. This research is expected to be able to help the users in knowing the blockage on water flow and monitored around in realtime.

ABSTRACT: Disclosure and monitoring policy are studied, where disclosure relates to information about the monitoring system. A moral hazard model is presented where employee monitoring occurs with some exogenous probability and the owner privately learns whether he will be monitoring before the employee chooses his productive action. Disclosure policy is an owner choice between revealing to the employee whether he will be monitoring before the action (Disclosure) or remaining silent (Secrecy). The results rely on the joint presence of risk aversion and limited liability. Risk aversion creates an efficiency/risk tradeoff where secrecy obtains risk-sharing benefits. Limited liability reduces these benefits, allowing preference for disclosure. Lower monitoring probabilities increase the risk premium required to obtain effort with secrecy. For small monitoring probabilities, disclosure is preferred even though less efficient production is achieved, because disclosure provides a greater risk-sharing benefit. For high monitoring probabilities, secrecy is preferred because it leads to greater efficiency despite a greater risk premium.
