Abstract

The use of Common Object Request Broker Architecture (CORBA) has become one of the answer to the requirement for interoperability among the rapidly increasing number of hardware and software products available nowadays. CORBA has been introduced as a mechanism in a distributed computing environment in order to overcome recent interoperability issue. This mechanism allows distributed objects to communicate with each other, whether operate on remote devices or local devices, written in different languages or platforms, or at different locations on a network. In this paper, the concept of CORBA application as a middleware is presented. In order to understand this concept, a simple program to handle auction sale. This system is developed using JAVA programming language. This application is implemented on Windows Operating System (OS) and its method is being invoked by a client from the other machine that also runs in Windows OS. Along with this, the benefits of CORBA and its limitation are discussed in this paper.Keywords—CORBA concept; client-server; benefits of Corba; Application example

Abstract

The article is presenting how to implement the framework of scrum in IT service support domain and software quality assurance (SQA). Basicly, scrum framework is being used in other software development methods such as agile, but the reseach found that there is merely a few could support the software development. This framework could be implemented in small, medium and large projects. By promoting the usage of scrum framework could add more valu to organization and reach its goal. The collection of scrum framework implementation from previous researcher could present the real example of scrum framework in IT service domain and SQA. As this framework is still new in practice to IT domain, so that the guidance of this scrum framework will help developer to have more experience in applying in any software development projects. As the result, the company will enhance their business value

Abstract

Polluted estuaries can result in oxygen depletion, accumulation of toxic substances and heavy metals, and become a source of pathogens that are threaten for cultivated aquatic biota and coastal tourists. This research aims to analyze 1) pollution index; 2) status of water pollution in Bangka Jaya and Tanoh Anoe Regencies; and 3) testing the level of effectiveness of Layered Filtered Treatment (LFT) using analysis of removal efficiency and degradation capacity on water quality. LTF is a filtration media that composed of coconut husk, membrane and coffee grounds made into briquettes, LFT used to filter polluted estuary waters. The pollution parameters analyzed at Bangka Jaya were nitrate, phosphate, Escherichia coli bacteria and ammonia, while the pollution parameters at Tanoh Anoe were heavy metals Pb and Cd. The research results showed that the pollution status of Bangka Jaya estuary (A1) and Bangka Jaya coastal waters (A2) are moderately polluted, with indices at stations A1, A2 and A3 respectively is 9.19; 8.42; and 8.42. Meanwhile, the water pollution status in Tanoh Anoe estuary are heavily polluted (station B1) and moderately polluted (station B2) with the pollution index at each station being 14.07 and 9.36. The conclusion of this research is that LFT has not been proven capable of removing and degrading the pollutant parameters nitrate, phosphate, E.coli bacteria and ammonia, however the LFT method has been proven capable of increasing dissolved oxygen, stabilizing sea acid, temperature and also water salinity. LFT has also been proven to be able to prevent ocean acidification with a degradation capacity percentage of 6.60%.
