Abstract

A chatbot is a computer program designed to simulate intellectual dialogue with one or more humans, either through text or audio. Chatbots serve specific functions and roles, including simplifying the process of responding to inquiries—where responses are not required to be immediate—and allowing questions to be answered in real time.The objective of this research is to develop an information chatbot for Puskesmas Cilimus to support real-time information services. By using a Natural Language Processing (NLP) approach, the development process helps design and build an application that facilitates interaction between humans and computer systems. The Rational Unified Process (RUP) method is used for system design, which includes the phases of Inception, Elaboration, Construction, and Transition.The result of this study is a Telegram-based information chatbot service that can assist users in accessing information at any time without time constraints.

Abstract

Keamanan dokumen akademik pada sistem informasi sekolah merupakan aspek krusial untuk menjamin integritas dan keaslian data. Penelitian ini mengusulkan pengembangan modul tanda tangan digital berbasis superenkripsi RSA–ECDSA dengan fungsi hash SHA-512 pada sistem Buku Induk Nilai berbasis web. Metode pengembangan menggunakan Rapid Application Development (RAD) untuk menghasilkan prototipe cepat sesuai kebutuhan pengguna. Proses implementasi meliputi hashing dokumen menggunakan SHA-512, enkripsi hasil hash dengan RSA, penandatanganan menggunakan ECDSA, serta penyisipan tanda tangan digital dalam bentuk QR-Code ke dokumen ekspor. Pengujian dilakukan pada 30 sampel dokumen dengan variasi ukuran 10 KB–1 MB melalui pendekatan blackbox testing. Hasil uji menunjukkan tingkat keberhasilan verifikasi dokumen sebesar 100%, waktu rata-rata proses penandatanganan 1,25 detik, dan waktu verifikasi 0,98 detik. Sistem terbukti mampu mendeteksi perubahan sekecil 1 byte, menjaga integritas dokumen, dan memberikan tingkat keamanan setara 112–128 bit sesuai standar kriptografi modern. Temuan ini menegaskan efektivitas superenkripsi RSA–ECDSA dalam meningkatkan keamanan dokumen akademik serta menawarkan solusi yang efisien, portabel, dan dapat diverifikasi secara mandiri melalui QR-Code.

Abstract

Complaints are an important part of village governance as a means for the community to convey their aspirations, complaints, and reports related to public services. In some areas, the complaint process is still carried out manually due to limited digital infrastructure, resulting in slow handling and poor documentation. This study aims to develop a Progressive Web App (PWA)-based public complaint system that can still be used even without an internet connection, utilizing Service Worker, Cache API, and IndexedDB technologies. The system was developed using the Rational Unified Process (RUP) approach with the stages of inception, elaboration, construction, and transition. System modeling used Unified Modeling Language (UML) to describe the process flow. The programming language used is Hypertext Preprocessor (PHP). Testing was conducted using the black box method and the System Usability Scale (SUS). The test results showed a SUS score of 73.3, which falls into the “Good” category. This research resulted in a public complaint system that continues to function even without an internet connection, so that complaints made by the public can still be sent without being constrained by the internet network.
