PEMANFAATAN SISTEM INFORMASI UNTUK PENGELOLAAN DATA KOPERASI SIMPAN PINJAM MENGGUNAKAN VISUAL BASIC

Information System for Savings and Loans Cooperatives Using Visual Basic Case Studies at the Semarang Regency Regional Employment Agency is an information system created to overcome data processing problems which are still in the form of manual bookkeeping and even there is no evidence of deposit transactions, loans and installments and existing storage can be overcome by creating an information system for processing data on savings and loan cooperative transactions and creating a more secure and efficient data storage information system. Savings and loan information system design methods are made using R&D, Flowchat, DFD, ERD, and Normalization methods. The program used to create this application uses the Microsoft Visual Basic 6.0 programming language and MySQL as database management. The results of this study indicate that the savings and loan cooperative information system that is applied in the Savings and Loans Cooperative of the Semarang Regency Regional Civil Service Agency can be used to process member data, process savings data, process loan data, process data that has been paid off, process SHU distribution data, and make reports. finances safely and efficiently.

Do secure information system design methods provide adequate modeling support?

Information system development (ISD) methods lack security features. To address this problem, various secure information system (SIS) design methods have been proposed. An important feature of these methods is modeling support, which manifests itself through modeling notations. This paper explores the extent to which the alternative SIS design methods offer modeling support. The results suggest that extant SIS design methods provide only limited modeling support. No single SIS design method offers comprehensive modeling support. This result has implications for practice and research. Practitioners may need to combine different SIS design methods for the development of secure information systems (IS). In turn, scholars and SIS design method developers should ensure that future SIS design methods offer comprehensive modeling support. Finally, empirical studies should be conducted to explore the usability of the current conceptual models of secure systems design methods in practice.

A proposal for a framework to classify and review contingent information system design methods

Today, information systems (IS) and related information technologies occupy a prime position in our organizations. However, over 60% of IS projects represent a failure. In this boarder, the contingent and modular design methods, which enable to adapt the steps of the project to the context and to use several method fragments and techniques in a combined manner, seem promising. However, they do not reach expected efficiency since the failure rate remains high. Existing propositions emphasise the description of such methods, but there is no means to understand the underlying logic of integrated contingency approaches. Such means are however essential to help clarifying and analysing existing contingent approaches and to assist researchers in developing more innovative contingent methods. The paper is an attempt to explore some of the issues underlying contingent IS design methods and to propose a framework for their classification. The framework is a 3-dimensional framework which advocates that a contingent design method can be well defined by its contingency level, characterization type and adaptation mode. After reviewing eight existing methods according to the framework, these are analysed and further research directions are highlighted.

Systems characteristics in information systems design

Although many information systems (IS) design methods and techniques are available to IS professionals, none of them completely supports the design process. One of the problems is that there is a mismatch between IS design methods and the system to be built. Actually, in designing an IS, the methods or techniques employed should match the types and characteristics of the system to be built. This paper will explore the relationship between IS types/characteristics and systems design methods, and provide IS designers with a systems framework to develop methods or techniques that match the types and characteristics of IS. 33 refs.

The Foundation Role for Theories of Agency in Understanding Information Systems Design

In this paper we argue that theories of agency form a foundation upon which we can build a deeper understanding of information systems design. We do so by firstly recognising that information systems are part of purposeful sociotechnical systems and that consequently theories of agency may help in understanding them. We then present two alternative theories of agency (deliberative and situational), mainly drawn from the robotics and artificial intelligence disciplines, and in doing so, we note that existing information system design methods and ontological studies of those methods implicitly adhere to the deliberative theory of agency. We also note that while there are advantages in specific circumstances from utilising the situated theory of agency in designing complex systems, because of their differing ontological commitments, such systems would be difficult to analyse and evaluate using ontologies currently used in information systems. We then provide evidence that such situational information systems can indeed exist, by giving a specific example (the Kanban system), which has emerged from manufacturing practice. We conclude that information systems are likely to benefit from creating design approaches supporting the production of situational systems.

PEArL: A Systems Approach to Demonstrating Authenticity in Information Systems Design

The process of information systems (IS) design has been dominated by the demands inherent in providing a technical solution to a perceived problem or need. Engineering IS design methods applied in order to satisfy the problem situation tend to have a preoccupation with verifying specifications as being mathematically correct. Difficulties arise when the ideas underpinning verification are extended in an attempt to ‘prove’ the validity of a proposed design for an IS. A pure engineering approach does not facilitate a response to the subjective elements within social situations, which experience has shown to be essential in demonstrating the pertinence of new designs to those concerned. We suggest that, by applying interpretivist systems ideas, it is possible to support concerned individuals in reflecting upon crucial aspects of the inquiry, enabling those individuals to judge the relevance or ‘authenticity’ of the learning, according to their own values and beliefs. The elements of participants, engagement, authority, relationships and learning are suggested as being crucial. These make up the mnemonic PEArL, which is offered as an aide-mémoire for those concerned with IS design.

Information systems security design methods

The security of information systems is a serious issue because computer abuse is increasing. It is important, therefore, that systems analysts and designers develop expertise in methods for specifying information systems security. The characteristics found in three generations of general information system design methods provide a framework for comparing and understanding current security design methods. These methods include approaches that use checklists of controls, divide functional requirements into engineering partitions, and create abstract models of both the problem and the solution. Comparisons and contrasts reveal that advances in security methods lag behind advances in general systems development methods. This analysis also reveals that more general methods fail to consider security specifications rigorously.
