Abstract

ABSTRACT. Micro, Small, and Medium Enterprises (MSMEs) in Gorontalo City have adopted social media for marketing purposes; however, its utilization remains suboptimal due to time constraints and a lack of strategic understanding regarding digital content management. Preliminary surveys indicate that many MSMEs lack a structured posting schedule and face difficulties in objectively measuring promotional effectiveness. As a practical solution, this research designs and develops a web-based Digital Content Management Information System. The primary contribution of this study is the provision of a centralized platform for MSMEs to plan and manage posting schedules, integrated with an innovative "Interaction Level Assessment" feature. This feature converts complex interaction metrics into simplified, easy-to-understand performance scores (Engagement Rate values and Grades A-D) and provides follow-up recommendations for each uploaded content. The system was developed using the Waterfall method (Pressman), involving systematic stages from requirements analysis through interviews and surveys, system design using Unified Modeling Language (UML), to code implementation. Functional testing was conducted using the Black Box Testing method, which confirmed that the system operates according to user requirements and planned specifications.ABSTRAK. Usaha Mikro, Kecil, dan Menengah (UMKM) di Kota Gorontalo telah mengadopsi media sosial untuk keperluan pemasaran, namun pemanfaatannya belum optimal akibat keterbatasan waktu dan kurangnya pemahaman mengenai strategi manajemen konten digital. Survei awal menunjukkan bahwa banyak pelaku UMKM tidak memiliki jadwal unggahan yang terstruktur dan kesulitan mengukur efektivitas promosi secara objektif. Sebagai solusi praktis atas permasalahan tersebut, penelitian ini merancang dan membangun Sistem Informasi Manajemen Konten Digital berbasis web. Kontribusi utama dari penelitian ini adalah penyediaan platform terpusat bagi UMKM untuk merencanakan dan mengelola jadwal unggahan, serta fitur inovatif "Interaction Level Assessment". Fitur ini mampu mengonversi metrik interaksi yang kompleks menjadi skor performa yang sederhana dan mudah dipahami (nilai Engagement Rate dan Grade A-D), serta memberikan rekomendasi tindakan lanjut bagi setiap konten yang diunggah. Pengembangan sistem menggunakan metode Waterfall (Pressman) yang meliputi tahapan sistematis mulai dari analisis kebutuhan melalui wawancara dan survei, perancangan sistem dengan Unified Modeling Language (UML), hingga tahap implementasi kode. Pengujian fungsionalitas sistem dilakukan menggunakan metode Black Box Testing, yang menunjukkan bahwa sistem telah berfungsi sesuai dengan kebutuhan pengguna dan spesifikasi yang direncanakan.

Abstract

Social media has become a primary platform for the public to express opinions on government policies, including Indonesia’s Free Nutritious Meal (MBG) program. This study analyzes public sentiment toward MBG by comparing the K-Nearest Neighbor (KNN) and Naive Bayes algorithms. A total of 9,723 tweets were collected, and after removing the neutral category, 6,322 tweets remained (3,955 positive and 2,367 negative), indicating a dominance of positive opinions. The experimental results show that KNN performed best at k=9 with a 70:30 split, achieving an accuracy of 72.27% and an F1-score of 65.92%, with an average cross-validation accuracy of 73.30%. Naive Bayes with parameter α=0.5 consistently outperformed KNN, achieving an average accuracy of 79.61% and an F1-score of 77.33%, along with better precision–recall balance. The main contribution of this research is providing empirical evidence that Naive Bayes is more effective than KNN for sentiment analysis of Indonesian-language text with a large dataset, as well as offering a methodological framework applicable to the evaluation of other public policies.Media sosial menjadi ruang utama masyarakat untuk mengekspresikan opini terhadap kebijakan publik, termasuk Program Makan Bergizi Gratis (MBG) di Indonesia.

Abstract

The Family Information System (SIGA) is a strategic application of BKKBN in Gorontalo Province that supports national family data management. However, during implementation, it faces obstacles in the user interface (UI) and user experience (UX), which affect its effectiveness. This research aims to optimize the UI/UX SIGA design using the Design Thinking approach. This research method applies five stages (empathize, define, ideate, prototype, test) and evaluation of the System Usability Scale (SUS). The initial SUS test for the SIGA application yielded an average score of 41.84, indicating a very low level of usability (Grade F). After a design iteration based on user feedback, the new prototype was tested and showed a significant increase in SUS score to 88.36 (Grade A). These results show that the Design Thinking approach is practical in identifying problems and creating optimal UI/UX solutions. This research contributes practically to improving the usability of SIGA and academically to the Human-Computer Interaction (HCI) literature on public sector information systems.Sistem Informasi Keluarga (SIGA) merupakan aplikasi strategis BKKBN di Provinsi Gorontalo yang digunakan untuk mendukung pengelolaan data keluarga secara nasional.

Abstract

The Integrated Academic Information System (SIAT) at Universitas Negeri Gorontalo has been widely used to support academic activities, but issues such as slow performance under heavy load, data security risks, and inconsistent interface design remain. Previous studies on academic information systems often focus on limited quality aspects or rely on single evaluation tools, leaving a research gap in providing a comprehensive quality assessment. This study aims to evaluate SIAT using the ISO/IEC 25010 standard with multi-tool approach, offering a replicable framework for system evaluation across higher education institutions. A quantitative descriptive method was applied, combining expert judgment for Functional Suitability, GTMetrix for Performance Efficiency, PowerMapper for Compatibility, SUS for Usability (30 respondents), WAPT for Reliability, Acunetix for Security, Land’s instrument for Maintainability, and cross-device/browser testing for Portability. The results show high scores in Functional Suitability (97.3%), Performance Efficiency (95.4%), Reliability (99.6%), and Portability (100%). Usability scored 68 (marginally acceptable), while Security revealed severe vulnerabilities, and Maintainability was hindered by interface inconsistencies and lack of formal testing. This research not only to evaluating SIAT but also to introducing a replicable multi-tool evaluation framework based on ISO/IEC 25010, which can inform improvements in similar systems at other universities.Sistem Informasi Akademik Terpadu (SIAT) di Universitas Negeri Gorontalo telah digunakan untuk mendukung aktivitas akademik, namun masih menghadapi masalah seperti kinerja yang lambat pada beban tinggi, kerentanan keamanan, dan inkonsistensi antarmuka. Penelitian sebelumnya umumnya hanya menilai sebagian aspek kualitas atau menggunakan satu alat uji, sehingga menimbulkan kesenjangan penelitian dalam penyediaan evaluasi kualitas yang menyeluruh. Penelitian ini bertujuan mengevaluasi SIAT berdasarkan standar ISO/IEC 25010 dengan pendekatan multi-tool, serta menawarkan kerangka evaluasi yang dapat direplikasi untuk sistem serupa di perguruan tinggi lain. Metode yang digunakan adalah kuantitatif deskriptif dengan kombinasi berbagai instrumen: penilaian ahli untuk Functional Suitability, GTMetrix untuk Performance Efficiency, PowerMapper untuk Compatibility, SUS untuk Usability (30 responden), WAPT untuk Reliability, Acunetix untuk Security, instrumen Land untuk Maintainability, serta pengujian lintas perangkat/browser untuk Portability. Hasil penelitian menunjukkan SIAT unggul pada Functional Suitability (97,3%), Performance Efficiency (95,4%), Reliability (99,6%), dan Portability (100%). Usability memperoleh skor 68 (cukup), sementara Security menunjukkan kerentanan tinggi, dan Maintainability masih terbatas karena inkonsistensi tampilan serta belum adanya pengujian formal. Penelitian ini tidak hanya dalam evaluasi SIAT, tetapi juga melalui pengusulan kerangka evaluasi multi-tool berbasis ISO/IEC 25010 yang dapat direplikasi dan bermanfaat untuk peningkatan sistem informasi akademik di universitas lain.
