Abstract

The culinary industry in Indonesia has experienced significant growth, yet many restaurants still rely on manual ordering systems. This study addresses the operational inefficiencies at RM Solideo Kuliner, where manual ordering causes long queues, order recording errors, and customer dissatisfaction. The research aims to design an Android-based online food ordering information system to overcome these challenges. The Agile methodology was employed for system development due to its flexibility in accommodating changing business requirements. Data collection involved interviews with restaurant stakeholders and direct observation of existing processes. The system was developed using Flutter framework and Dart programming language, with Firebase serving as the backend database. The resulting Android application enables customers to register, login as guests, browse menus, place orders, select payment methods, and track order status in real-time. Black Box testing confirmed that all features function according to specified requirements. Usability evaluation with 10 respondents yielded positive feedback, with 90% rating the application as easy to use and having an attractive interface. The implementation successfully improved operational efficiency by reducing order processing time by 60% and minimizing recording errors to less than 2%. This digital transformation demonstrates the potential for technology adoption in enhancing customer experience and business operations in the culinary sector.

Abstract

The rapid digitization of healthcare in Indonesia reveals significant usability gaps, with popular applications like Halodoc and Alodokter showing inconsistent System Usability Scale (SUS) scores. Specifically, existing platforms often prioritize feature completeness over user-centered interface design, resulting in navigation ambiguities. Background information highlights that poor UX leads to user abandonment. Therefore, optimizing interface design is crucial. This research aims to design a user-centered health application prototype, "Medimate," to address critical interface and navigation deficiencies. The study employs a mixed-methods approach, utilizing the five-stage Design Thinking framework (Empathize, Define, Ideate, Prototype, Test) for development and SUS for quantitative evaluation. Data collection involved in-depth interviews with two user personas to identify pain points, followed by usability testing with 36 respondents. Responses were collected via Google Forms to facilitate remote data gathering. Results indicate that "Medimate" effectively resolves identified UX issues, achieving a mean SUS score of 80.42, classified as Grade A- (Excellent). Key design improvements include transparent pricing structures, intuitive navigation flows, and integrated mental health features. The study concludes that the Design Thinking approach significantly enhances usability metrics in health applications. "Medimate" demonstrates high acceptability and viability for further functional development. Future research should expand sample sizes to include broader demographics and evaluate backend performance. This study contributes a validated design framework for improving digital health accessibility in emerging markets.

Abstract

Dominasi sistem operasi Android di kalangan pelajar belum dimanfaatkan secara optimal sebagai media kreasi. Kendala utama dalam pembelajaran pemrograman di sekolah adalah tingginya tingkat kesulitan (learning curve) pada bahasa pemrograman berbasis teks. SMK Yadika Manado membutuhkan metode pembelajaran alternatif yang dapat mempermudah siswa memahami konsep dasar pemrograman mobile secara instan dan menyenangkan, guna mengatasi kejenuhan dalam belajar teori. Pelatihan visual programming menggunakan MIT App Inventor adalah pendekatan yang dipilih untuk memungkinkan siswa menyusun kode layaknya menyusun puzzle. Tahapan kegiatan meliputi pra-tes, tutorial pembuatan aplikasi kalkulator, uji coba aplikasi, dan pasca-tes. Hasil pelatihan menunjukkan bahwa 23 siswa berhasil membuat aplikasi fungsional pertama mereka dalam waktu singkat. Data kuesioner memperlihatkan bahwa 91,3 % peserta merasa keterampilan pemrograman mobile akan bermanfaat di masa depan. Perancangan Visual Aplikasi dengan MIT App Inventor adalah solusi tepat guna untuk mengakselerasi pemahaman pemrograman mobile di tingkat SMK, mengubah posisi siswa dari sekadar pengguna pasif menjadi pencipta teknologi aktif.

Abstract

Decentralized public sector information systems frequently exhibit operational vulnerabilities due to fragmented IT governance practices, undermining data reliability and public service delivery. This study evaluates the governance maturity of a Public Data Dissemination Platform operated by a regional statistical office to establish a standardized capability baseline. Employing a descriptive quantitative design, the research applies the COBIT 2019 framework across the Deliver, Service, and Support (DSS) and Monitor, Evaluate, and Assess (MEA) domains. Data were collected through semi-structured interviews, system observation, and archival documentation, then quantified using CMMI-aligned capability scoring and calibrated gap analysis. Empirical findings reveal that both domains operate at Level 1 (Performed Process), with aggregate scores of 1.16 for DSS and 0.75 for MEA. The most critical deficiencies occur in incident management (DSS02, Gap = 3) and external compliance monitoring (MEA03, Gap = 3), while assurance mechanisms (MEA04) remain entirely unestablished at Level 0. These results indicate that current operations rely on ad hoc procedures rather than standardized controls. Consequently, the study provides a phased remediation roadmap prioritizing formal documentation, structured service tracking, and independent evaluation functions. The framework offers a replicable diagnostic model for subnational agencies seeking to transition from reactive maintenance to predictable, audit-ready IT governance.
