Abstract

Penelitian ini membandingkan efisiensi orkestrasi kontainer menggunakan Kubernetes lokal (Minikube) dengan eksekusi kontainer langsung menggunakan Docker dalam pengelolaan aplikasi Node.js. Eksperimen dilakukan di lingkungan lokal untuk mereplikasi perilaku cloud-native secara terukur. Tiga endpoint diuji untuk merepresentasikan karakter beban berbeda: /hello (ringan), /load (CPU intensif), dan /sleep (latensi I/O). Pengujian beban menggunakan Apache JMeter dengan 1000–1500 permintaan per menit selama 10 menit pada setiap endpoint dan diulang lima kali. Hasil menunjukkan Docker secara konsisten mencapai latensi lebih rendah dan throughput lebih tinggi dibanding Minikube, terutama pada /hello dan /load. Temuan ini menegaskan bahwa ketiadaan overhead orkestrasi membuat Docker lebih efisien untuk skenario beban ringan hingga menengah serta pengujian lokal. Minikube tetap relevan berkat fitur orkestrasi seperti penskalaan, pemulihan mandiri, dan pembaruan bertahap, namun menimbulkan biaya kinerja yang terukur. Dengan demikian, untuk kasus tanpa kebutuhan orkestrasi kompleks pada skala kecil hingga menengah, Docker menjadi pilihan yang lebih efisien, sedangkan Minikube lebih tepat saat kebutuhan keandalan dan manajemen layanan terdistribusi menjadi prioritas.

Abstract

The “Puji Lontar” palm sugar business group in Tianyar Barat Village, Kubu District, Karangasem Regency, Bali Province, still faces traditional drying methods that depend on the weather, resulting in uneven product moisture content and difficulty meeting market standards (maximum 3%). Downstream, sales are still predominantly conventional (price around IDR 12,000 per ¼ kg), packaging and branding are not yet strong, and financial records and business planning have not been developed. This community service program aims to improve production efficiency and marketing performance through the implementation of IoT drying technology, accompanied by digital marketing training and strengthening MSME management. The activity was carried out for eight months through stages of preparation, socialization, training, mentoring, and evaluation; materials included equipment operations and maintenance, packaging and brand identity, creation of marketplace/website/social media accounts, as well as recording daily transactions and preparing business plans/capital proposals. The evaluation results showed that partners were able to operate the drying technology independently, the drying process was more controlled so that the product moisture content could be maintained below 3%, and the digital marketing strategy drove an increase in turnover of around 25%. This program strengthens the competitiveness of palm sugar MSMEs while supporting the achievement of higher education IKU and SDGs.

Abstract

The use of information technology in the education sector has become an unavoidable necessity, particularly through the use of school websites as digital information service centers for students, teachers, parents, and the general public. School websites serve not only as a medium for conveying information but also as a means of communication, transparency, and support for academic activities. To optimally fulfill these roles, a website must be able to deliver good performance, fast access, high stability when there is an increase in the number of visitors, and adequate security to protect user data and activities. In Buleleng Regency, 17 state senior high schools (SMAN) have utilized official websites as part of their information services and digital administration needs. However, increased traffic, especially during certain times such as new student admissions or school announcements, often triggers high workloads (stress) on servers. This condition has the potential to reduce response speed, hinder user access, and even open up opportunities for security threats such as DDoS attacks and hacking attempts. This study aims to evaluate the technical performance, load resilience, and security aspects of the websites of senior high schools in Buleleng Regency using three automated testing tools: GTMetrix, LoadImpact K6.io, and OWASP ZAP Scan. This approach draws on previous research on website performance measurement, load testing, and user experience. The evaluation results are expected to provide a comprehensive overview of the actual condition of school websites and generate strategic recommendations to improve system speed, stability, and security. Furthermore, the findings from this testing serve as a basis for developing improvement measures so that school websites in Buleleng Regency can support digital education services more optimally, responsively, and securely.
