Abstract

The rapid growth of e-commerce has created new challenges in logistics optimization, particularly in terms of delivery route efficiency. This research develops a dynamic programming model to optimize delivery routes in the context of e-commerce in Indonesia. Using a modified Vehicle Routing Problem with Time Windows (VRPTW) approach, we implemented an algorithm that considers various factors such as distance, time, and cost. Simulations using synthetic datasets showed efficiency improvements of 18.7% in travel distance and 22.3% in delivery time compared to conventional methods. Field trials with an e-commerce partner resulted in a 21.5% reduction in travel distance and an increase in on-time delivery rate from 87% to 94%. Sensitivity analysis revealed that the algorithm's performance is most affected by demand fluctuations and changes in traffic conditions. Implementation challenges include integration with existing systems and consideration of workforce impact. This research opens avenues for further development in algorithm scalability, integration of sustainability factors, and adaptation to various geographical contexts, demonstrating significant potential for improving e-commerce logistics efficiency in the future.

Abstract

Peningkatan minat masyarakat Indonesia terhadap bahasa Jepang mendorong kebutuhan akan media pembelajaran yang lebih interaktif dan fleksibel. Namun, banyak aplikasi yang tersedia masih terbatas pada penyajian materi tanpa sistem progres belajar yang adaptif. Penelitian ini bertujuan untuk mengembangkan aplikasi mobile “Andana” sebagai platform pembelajaran bahasa Jepang interaktif berbasis Flutter dan Firebase. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan pendekatan software engineering. Proses pengembangan mencakup analisis kebutuhan, perancangan sistem, implementasi, dan pengujian fungsional. Data penelitian bersumber dari hasil uji coba fungsionalitas dan evaluasi performa aplikasi oleh pengguna. Aplikasi Andana dirancang dengan dua peran utama, yaitu pengguna dan admin, serta dilengkapi fitur pembelajaran berbasis multimedia (PDF, video, audio), flashcard, latihan mendengarkan, berbicara, dan sistem catatan pribadi. Hasil penelitian menunjukkan bahwa seluruh fungsi aplikasi berjalan dengan baik, dengan sinkronisasi data real-time dan tampilan antarmuka yang responsif. Integrasi antara Flutter dan Firebase terbukti mendukung pengelolaan data pengguna dan pembaruan konten secara dinamis. Kontribusi penelitian ini terletak pada pengembangan model aplikasi pembelajaran berbasis cloud yang adaptif dan mudah dikembangkan. Implikasinya, aplikasi Andana berpotensi menjadi media belajar bahasa Jepang yang efisien, menarik, serta dapat diadaptasi untuk bahasa asing lainnya di masa mendatang.
