One of the features in the Feeder PDDIKTI application is the student activity feature. The feature is used to record student activities with participants' activities, supervisors and examiners. The problem with the Feeder PDDIKTI application when recording student activities is that the operator must input data one by one to the application. Therefore DIKTI also provides web services that can be used so that the recording process can be better.Implementation of recording student activities using web services on the Feeder PDDIKTI with extreme programming methods is carried out in accordance with the stages. In the planning part, an analysis is carried out on the business needs and user stories, in the design, use case diagrams and activity diagrams are made, coding is done by implementing the design using the PHP programming language, and testing is done using black box testing.In running the application, upload excel files are used for student activity data, activity participants, supervisors and examiners. After the student activity is successfully uploaded an excel file is generated from the system which contains student activities that already have the id_akt_mhs attribute. These attributes will be used to link student activity data with activity participants, supervisors, and examiners when filling in data in an excel file. Applications made are not yet connected to the Academic Information System Application so that for future development it is expected to be able to connect and retrieve data directly from the Academic Information System Application.

Granularity is often ignored when designing geospatial Web services. Choices relating to granularity affect service interfaces, data storage and organization, and XML format design. This chapter highlights the importance of analyzing usage and performance requirements when deciding on granularity choices in the design of geospatial Web services. Often, instead of making design decisions based on these requirements, geospatial services are implemented using default, commonly used techniques which may reduce performance, increase complexity, or fail to fully meet user needs. This chapter discusses the importance of granularity in designing and implementing geospatial Web services and provides common examples that highlight the different approaches to granularity which are available.

An emerging class of technologies defined as Service-Oriented Architecture (SOA) has been heralded as the answer for inflexible IT architecture and promises to reduce operational barriers of current IT infrastructures. In SOA, loosely coupled Web services are integrated to provide dynamic digital capabilities within and across enterprise boundaries. Little research exists on development processes of information systems using Web services and against certain development metrics. One way to perform such research is to propose a development approach, identify the metrics, and embed the metrics into the technique of service composition to allow system development with desired characteristics. This paper reports an approach to information system development based on Web services composition and the metrics designed for such approaches. This approach is based on semi-automatic, interactive, and iterative Web service composition -- a hybrid technique based on developing and searching an AND/OR graph for composite services discovery while taking into consideration human judgment for solution selection and validation by interactions in an iterative way. The composition process leverages historical Web service usage data and provides helpful suggestions to the users regarding available component services. The authors propose that the metrics can investigate the characteristics of such development approaches.
