Java for parallel computing and as a general language for scientific and engineering simulation and modeling

We discuss the role of Java and Web technologies for general simulation. We classify the classes of concurrency typical in problems and analyze separately the role of Java in user interfaces, coarse grain software integration, and detailed computational kernels. We conclude that Java could become a major language for computational science, as it potentially offers good performance, excellent user interfaces, and the advantages of object-oriented structure

How to Cope With Strategic Infrastructure Disparities in West Java? (A Post-Pandemic Economic Recovery Analysis )

The availability of energy and telecommunication facilities has been claimed as two strategic infrastructures supporting the West Java economy during and the post-pandemic. However, researchers found that the West Java electricity and telecommunication infrastructure is inter-regionally inequitable. This paper aims to identify the recent electrical energy access of households and the existing condition of telecommunication infrastructure; to configure the investment data in the last five years, and to analyze the opportunities and challenges of investment, and development of electricity and telecommunication network in the future. This research uses the Desk Study method by collecting primary data from bureaucrats and secondary data from relevant Government agencies. The results show that electricity and telecommunications infrastructure conditions in West Java are still unequal between the Northern and Southern regions, particularly in terms of electrification ratio, cellular phone signal strength, and internet signal quality. Furthermore, investment in West Java was very unequal, with about two-thirds of foreign and domestic investment in Bekasi and Karawang districts in the last-five-years. This study formulates recommendations for policy in the investment, electricity, and telecommunications sectors in dealing with interregional infrastructure development disparities as well as economic challenges during and after the pandemic

The Effect Of HDI, Minimum Wage And Regional Income On Inclusive Economic Development Index In Central Java, 2018 – 2021

During the Covid-19 pandemic, Central Java was still able to increase its inclusive Economic Development Index score. But nationally, Central Java's ranking has declined. In addition, in the first pillar, Central Java's IPEI is below the province with an absolute IPEI score, while other provinces are below Central Java. The purpose of this research is to see the effect of HDI, minimum wage, General Allocation Fund (GAF), Local Own-source Revenue and village funds for IEDI in Central Java in 2018-2021. The locations that are the object of this research are every district/city in Central Java. The type of data used in this study is secondary data so that data collection is carried out by other parties by recording existing data. The analytical method used is panel data regression analysis. The results of this study show that HDI and GAF have a positive and significant effect on IEDI while minimum wage, Local Own-source Revenue, and village funds have no effect on IEDI for each Regency/City in Central Java in 2018-2021. Taken together the variables HDI, minimum wage, General Allocation Fund (GAF), Local Own-source Revenue and village funds affect for IEDI in Central Java in 2018-2021. Keywords: IEDI, HDI, General Allocation Fund, Minimum Wage, Local Own-source Revenue, village funds

The Spatial Effect of Agricultural Sector Growth in West Java: A Spatial Approach to Panel Data

  The agricultural sector is strategic and the third-largest contributor to the GRDP of West Java Province, but its growth has slowed during the 2016–2019 period. The slow growth rate can be caused by the determinants of the growth of the agricultural sector itself and is very likely to be affected by the spatial interaction between regions in the province. Therefore, this study aims to analyze the spatial effect between regions on the growth of the agricultural sector in West Java and identify the factors that influence the growth of the agricultural sector within the province by using spatial analysis of panel data. The results reveal that the appropriate model is a fixed effect spatial error model, which shows an effect of spatial interaction between regions on the growth of the agricultural sector in West Java Province. The factors that affect the growth of the agricultural sector are agricultural credit, agricultural road infrastructure, and diversification of economic activities.   Keywords: agricultural sector growth, spatial autoregressive, spatial error model, spatial panel dat

A real-time distributed analysis automation for hurricane surface wind observations

From 1993 until 1999, the Hurricane Research Division of the National Oceanic and Atmospheric Administration (NOAA) produced real-time analyses of surface wind observations to help determine a storm\u27s wind intensity and extent. Limitations of the real-time analysis system included platform and filesystem dependency, lacking data integrity and feasibility for Internet deployment. In 2000, a new system was developed, built upon a Java prototype of a quality control graphical client interface for wind observations and an object-relational database. The objective was to integrate them in a distributed object approach with the legacy code responsible for the actual real-time wind analysis and image product generation. Common Object Request Broker Architecture (CORBA) was evaluated, but Java Remote Method Invocation (AMI) offered important advantages in terms of reuse and deployment. Even more substantial, though, were the efforts towards object-oriented redesign, implementation and testing of the quality control interface and its database performance interaction. As a result, a full-featured application can now be launched from the Web, potentially accessible by tropical cyclone forecast and warning centers worldwide

THE ROLE THEOF FINANCIAL SERVICES AUTHORITY OF INDONESIA IN ORDER TO SUPPORT RURAL BANK/ISLAMIC RURAL BANK SUSTAINABILITY

The financial services authority (OJK) released data, in all of Indonesia half of the existing rural bank/Islamic rural banks have not met the minimum capital according to the Financial Services Authority Regulation (POJK) No.5/POJK.03 / 2015, which is IDR 3 billion and IDR 6 billion according to the size of their business so far, until December 31, 2019. Of course, with the data released by the OJK, many rural bank/Islamic rural banks will be forced to stop their operations. This research aims to analyze the role of POJK in supporting the sustainability of rural bank/Islamic rural banks. This research was carried out through the following stages: 1) the researcher conducted in-depth interviews with informants with a questionnaire guide; 2) to support the results of the interview, a literature study was also conducted, especially regarding regulations related to marketing products / services; 3) from the results of the interview tabulations are made to make it easier to read the results of the interviews, 4) discuss the tabulated data so that the condition of the rural bank/Islamic rural banks can be seen, 5) make conclusions. The results of this research found that rural bank/Islamic rural banks with a fund of Rp.500,000,000, - for the time being unable to cover the risk that must be borne by rural bank/Islamic rural banks, it is necessary to have a POJK which regulates the minimum core capital. POJK is also very much needed so that rural bank/Islamic rural banks can run their business more efficiently, effectively, transparently and accountably and be able to compete fairly with other financial institutions. Keywords : POJK, rural bank/Islamic rural banks sustainabilit

CLPL: Providing software infrastructure for the systematic and effective construction of complex collaborative learning systems

Over the last decade, e-Learning and in particular Computer-Supported Collaborative Learning (CSCL) needs have been evolving accordingly with more and more demanding pedagogical and technological requirements. As a result, high customization and flexibility are a must in this context, meaning that collaborative learning practices need to be continuously adapted, adjusted, and personalized to each specific target learning group. These very demanding needs of the CSCL domain represent a great challenge for the research community on software development to satisfy. This contribution presents and evaluates a previous research effort in the form of a generic software infrastructure called Collaborative Learning Purpose Library (CLPL) with the aim of meeting the current and demanding needs found in the CSCL domain. To this end, we experiment with the CLPL in order to offer an advanced reuse-based service-oriented software engineering methodology for developing CSCL applications in an effective and timely fashion. A validation process is provided by reporting on the use of the CLPL platform as the primary resource for the Master's thesis courses at the Open University of Catalonia when developing complex software applications in the CSCL domain. The ultimate aim of the whole research is to yield effective CSCL software systems capable of supporting and enhancing the current on-line collaborative learning practices.Peer ReviewedPostprint (author's final draft
