Abstract

In order to manage region water resources, Samarinda City has been collecting and managing all data of water resources. Good data management for water resources is needed to maintain water potential and suplay for this city and to control water quality from environmental pollution. The management of the existing water resources is needed by developing computer base structural database management system. The design of database system is used for development of software for water resources database management. The developed software can be used as Decision Support System to help city management and useful for information system to find out the potential of all water resources in Samarina. The output of this activity is software formanaging water resources in Samarinda city.

Abstract

Air quality changes due to the discharge gas in the vicinity of the location of bursts of mud in Sidoarjo disrupt the activities of people who live around. Concerns of the dangers caused by gas can increase the burden of the problems already experienced by them. Surveys measuring several parameters of gas in the villages around bursts mud needs to be done to provide clear information about the condition of air quality ambien. The measurement data processing and analysis results are expected to be used as an input when the decision is necessary to avoid another disaster due to the gas leak in that area.Keywords : Air Polution, Sidoarjo mudflow, Gas Consentration Monitoring, Bubble gas

Abstract

Gas produced by landfill is bio-gas that has a high concentration of methane that could cause global warming if not controlled. Good management of a landfill in controling the production of methane gas, can be used as an alternative sources of energy to produce electrical energy. Monitoring of methane gas production needs to be done continuously for the energy conversion process can take place perfectly without polluting the environment. Fixed monitoring system described in this paper is the result of design and development including hardware and software of monitoring technology for methane gas to facilitate research in doing observations of a landfill performance.keywords : final disposal, landfill gas, methane, landfill performance, fixed landfill gas monitoring system

In some areas the water have been polluted and certain natural conditions make it difficult for population to get their water. Pandeglang district is one of disadvantaged areas that experiencing problems of clean water needs, although this area has water resources are abundant. To help residents in solving this problem, it will be required an information of water treatment technology that can be widely accessed by residents in the Pandeglang district. By using opensource software applications, the information system for water treatment technology can be developed to provide information of appropriate technology needs for solving the problem of providing clean water in Pandeglang.keywords : information system for technology, clean water management, waste water treatment, environmental technology, hypertext document, free open sourcesoftware (OSS).
