Abstract

The rapid growth of information technology is influenced by globalization to accelerate access to information. This creates new problems, as differences must produce relevant information. Of course, system integration will be required. Web Service is a system integration solution that does not consider the platform, architecture, or programming language used in different sources. The security of web service is considered not yet implemented. The JSON Web Token (JWT) technology is an authentication mechanism for web service and will have a significant impact on data security. This implementation optimizes JWT security with the HMAC SHA-256 algorithm. Testing is conducted on two information systems by comparing the performance size when JWT technology is applied to Tim Bebersih Masjid Information System. The results show that the implementation of JWT on Windows Server 2019 (VM) is 462.8 ms with an average data size of 8.59 kb. Testing on the Windows 10 operating system obtained an average speed of 216.25 ms with an average data size of 8.59 kb. The result on Windows Server 2019 (VM) from the JWT performance test itself obtained the highest result, due to the use of virtual machine which is considered to consume a lot of RAM, resulting in performance that is 2 times higher.Keywords: Algorithm, HMAC SHA-256, JSON Web Token, Web Service, Virtual Machine

Abstract

Payung merupakan alat pelindung dari hujan dan panas sedangkan Geulis memiliki arti elok atau molek sehingga Payung Geulis memiliki arti payung cantik yang bernilai estetis. Terdapat dua motif payung geulis yaitu motif hias geometris berbentuk bangunan yang lebih menonjol seperti garis lurus, lengkung dan patah-patah, dan motif hias non geometris diambil dari bentuk alam seperti manusia, hewan dan tanaman. Payung geulis ini rangkanya terbuat dari bambu. Setelah dirangkai dan dipasangi kain dan kertas, ujung payung dirapikan dengan menggunakan kanji. Hasil survey diketahui bahwa Terhambatnya perkembangan usaha perajin payung karena perajin belum mau melakukan inovasi dan kreativitas produk dan masih tetap mempertahankan model dan motif lama masih dipertahankan. Para generasi muda enggan menekuni kerajinan membuat payung ini karena upahnya sangat kecil, membutuhkan ketelitian dan kesabaran dalam proses pembuatannya dan payung hanya dibuat berdasarkan pesanan serta pemasaran payung geulis masih terbatas dan modal kerja yang masih terbatas. Permasalahan yang saat ini dihadapi oleh kedua mitra diharapkan dapat memberikan bantuan untuk para generasi muda mau pemasarkan produk khas Tasikmalaya kepasar yang lebih luas dengan memanfaatkan aplikasi E-commece untuk usaha sampingan.Kata Kunci : e-Commerce, Payung Geulis, pemasaran.

Abstract

Digital transformation requires a modern management information system (MIS) to integrate data originating from various subsystems with heterogeneous formats, terminology and structure. Conventional schema mapping and extraction-transformation-load (ETL) based approaches are often incapable of addressing these challenges semantically. Semantic Ontologies offer conceptualization solutions that support interoperability and enable automated reasoning. This article presents a comprehensive understanding of the current literature on the application of semantic ontologies to information systems, highlighting the main contributions and limitations of previous research. The results show that most research still focuses on specific domains (culture, education, business), while semantic transmission across enterprise subsystems, ontology evolution issues, and performance evaluation measures are still rarely researched. Based on this mix, this research offers a semantic ontology framework designed for holistic data representation in integrated MIS, with the emphasis of ontology development across subsystems (ERP, CRM, SCM, HRIS), as well as performance evaluation measured in the aspects of interoperability, reasoning and query efficiency. It is hoped that this information contribution can strengthen the destruction of management systems while increasing the organization's adaptability to digital business dynamics.
