Abstract

the agriculture sector still faces fairly basic challenges, namely the quality problem and the increase in competitiveness through productivity and efficiency. This research determines the criteria for the best quality types of rice seeds and how to apply the Fuzzy Mamdani Method, to determine the quality of rice seeds in order to assist farmers in determining the quality of the best rice seeds. Mamdani fuzzy method is one example of a method that can help the optimal decision making process to solve practical problems. The problem solved is the determination of the best quality of rice seeds, based on established criteria, namely the type of rice, the shape of the rice, the color of the seeds, the age of the seeds, and roots. This is done to reinforce the output or output of each input variable membership. Then after the output input output variable is determined, the implementation of the rules for each parameter is carried out. After that do defuzzyfication with the centroid method. So that the output of one parameter is 60 with verry good information. This system was built with a website application where the application is able to help users to determine the quality of rice seeds and obtain information about the best seeds.

Abstract

In the era of the industrial revolution 4.0, there are very many significant changes to information technology. Advances in information technology so quickly innovate in various circles of society, thanks to this progress people can carry out all activities quickly and accurately. So that the effectiveness and efficiency of an organization or agency will be good. For example, in correspondence activities at the BKPSDM, Sukabumi Regency, initially letters were made by hand and then sent through intermediaries to certain individuals or agencies and vice versa then with the existence of information technology, correspondence activities were made easier in terms of manufacture and delivery. But with this convenience, there are still some obstacles experienced, namely the existence of data redundancy, accumulation of mail data, and the absence of multi users, this causes coordination problems in each field which has an impact on the delay in processing incoming and outgoing letters. This is because the company does not yet have a management support system to bridge correspondence activities and an unorganized reporting system. To overcome this, a suitable information system management model is needed, in this study the model used enterprise architecture with the Zachman Framework method. The focus of the problem in this research is to optimize the flow of correspondence and mail reporting activities using a website-based system as the medium. The results obtained from the Zachman Framework enterprise architecture are in the form of a blueprint or blueprint which will later be used as a reference in system implementation.

Abstract

According to Law No. 14/1967 concerning banking principles, it is explained that financial institutions are all entities that carry out their activities in the financial sector. withdraw money from the people and channel it into the people. Financial institutions have large data on financial facilities. In order to improve the quality of information disclosure to the public, financial institutions require the application of financial facilities as a means to register the financial facilities they have. This financial facility application consists of two platforms, namely web-based and mobile-based, so that a mechanism is needed to process data transactions between different platforms and can support interoperability between systems. Web service is a standard used in conducting data transactions between systems, because applications that exchange data can be written in a variety of programming languages and run on a variety of different platforms. The financial facility web service is built using node js with asynchronous javascript programming language so that it has better performance in handling requests. In this study, the web service was built using a REST architecture that uses the HTTP protocol to exchange data. Tests have been carried out to see the results of the web service using insomnia software. The results of this study indicate that web services can be a bridge for communication and data transactions between financial facility search applications and can run well and are able to support interoperability between systems.
