Abstract

The web-based application can ease business owners on promoting and giving the services to the customers. Nevertheless, nowadays there are still not many UMKMs (micro, small, and medium enterprises) in the Banyumas Regency that apply it. Many of them still preserve the conventional way by doing the transaction directly. This research is aimed to design and develop a web-based marketplace application, namely Cangkingan. That application is supposed to help UMKMs in Banyumas in managing inventory, processing orders, and marketing culinary products online. The outline of this research flow includes needs analysis, system design, system development, and system testing. The methods of data collection that are used are interview, observation, literature study, and questionnaire. The application design is created in various diagrams and user interface designs. The method of system development is scrum. This design and development are done within 10 sprints in which each sprint is held for two weeks. The application is built using MySQL, CodeIgniter framework, and PHP language. Testing of Cangkingan system is carried out using the ISO 9126 standard which consists of testing functionality, usability, reliability, efficiency, portability, and maintainability. The test result on most of the test aspects state that the application is satisfactory (good). Especially for the usability testing that is done to 36 respondents, Cangkingan gets excellent result. This test result is one of the proofs that the research purpose has been achieved and the application Cangkingan that has been developed is able to help the UMKMs with culinary products in Banyumas.

Abstract

Data analysis in research is an important thing to do after the research data is obtained. In designing a web application called Onti Measures, the files that have been executed have not been analyzed in more depth. Therefore, it is necessary to analyze the OWL (Web Ontology Language) files as test data for the Onti Measures application. This research aims to present a descriptive analysis of test data using three reasoners and compare their performance. The comparison of the three reasoners is seen based on running time, the performance of each reasoner, and the resulting inconsistency values. Those three reasoners are Hermit, JFact, and Pellet. In the Onti Measures application there are 10 inconsistency measures, namely drastic inconsistency measure, MI-inconsistency measure, MIc-inconsistency measure, Df-inconsistency measure, problematic inconsistency measure, incompatibility ratio inconsistency measure, MC-inconsistency measure, the nc-inconsistency measure, the mv-inconsistency measure, dan IDmcsinconsistency measure. The method used in this research is quantitative with a descriptive approach to analysis. The OWL fie input as test data is virus and disease ontology. The results of the descriptive analysis from this research include that 57.33% of the test data have an inconsistency value of 0 (consistent). Based on the performance of each reasoner in terms of processing ontologies, the three reasoners have almost the same capabilities. If it is seen from the resulting inconsistency values, the reasoner Pellet is better than the others. Meanwhile, based on the running time comparison, JFact is better than the other reasoners. The size of the ontology files does not affect the length of the running time.

Abstract

Inconsistency in an ontology can be a serious problem since it can mess up the information in the ontology. Ontology-based inconsistency measure gives inconsistency value of the whole base of the OWL ontology. It means the produced inconsistency value is used to evaluate its whole base. Based on this characteristic, there were 10 inconsistency measures created in the previous research and collected into one package of measures in an application program, namely Onti Measures. The application will not be useful if the measures do not work well. This problem leads to conduct evaluations. In this research, evaluations for the backend part of Onti Measures with the use of three kinds of OWL reasoners are done to know the performance of the application system with the comparison of each reasoner usage. The evaluations for the whole part of the application are not the scope of this research since they are only done for the backend part. Particularly, they are done with the black box method since the structure of the codes are not necessary to be known. They are evaluated with several OWL files as test cases and as the inputs of the backend program. The evaluation shows that the same inconsistent OWL file that is computed with a different type of inconsistency measure with any chosen reasoner may result in different inconsistency value. Other evaluations are provided. Overall, they show that Pellet is better than the two other reasoners and I_(D_f ) is more efficient than the other measures.

Abstract

Conventional application development often faces challenges like extensive code writing, long development times, high costs, and difficulties in maintenance and customization. Low-code programming offers an innovative solution by minimizing manual coding and enabling application creation through visual interfaces and drag-and-drop logic. This research explains the application of low-code programming technology in developing a petty cash transaction recording application at PT Bank Central Asia Tbk, specifically in the Corporate Communication & Social Responsibility Division. The low-code approach allows for faster, more efficient, and easier-to-maintain application development. The research uses the agile method, covering plan, design, develop, test, deploy, review, and launch stages. This case study, using the OutSystems platform, shows significant benefits such as increased development time efficiency, ease of maintenance, and flexibility in meeting dynamic business needs. The developed application can be integrated into the company's existing IT environment, improving the accuracy of petty cash transaction recording and reporting, and providing easy user access. In conclusion, low-code programming technology proves to be an effective solution for developing complex business applications efficiently in terms of time and cost.

Abstract

In the competitive and dynamic digital era, cooperatives must have systems that accommodate both operational needs and customers to improve service quality and customer satisfaction. However, Koperasi Nusantara Mandiri in Bandung Regency does not yet have a system that encompasses both aspects, rendering the cooperative's services ineffective and less competitive. Therefore, the cooperative requires a Customer Relationship Management (CRM) system to assist potential customers by providing loan eligibility calculation simulations. This research aims to implement a decision support method in a system using the waterfall methodology, which includes the stages of requirements, design, implementation, testing, and maintenance to develop a web-based CRM application. The application is designed and developed to help the cooperative manages the customer data, ease the business processes, and enhance effectiveness in both operations and customer analysis. Testing is conducted using the black box technique to ensure the application meets the specified requirements. The research results indicate that the developed CRM application functions well and meets the needs of Koperasi Nusantara Mandiri, thereby increasing the cooperative's operational effectiveness.
