Abstract

The purpose of this study is to optimize the performance of on-time delivery in the procurement process at PT Lautan Air Indonesia, where delivery delays reach 23% and significantly disrupt the reliability of the supply chain. On-time delivery is an important indicator of operational performance, reflecting the accuracy of planning, vendor collaboration, and supply chain execution. Persistent delays in the procurement process not only increase operational costs but also pose a risk to customer confidence and production continuity. Materials and methods. This research applies an integrative approach that combines Lean Thinking, Root Cause Analysis (RCA), and QCDSM (Quality, Cost, Delivery, Safety, Morale) framework. Lean Thinking is used to identify wastes such as waiting and delays, RCA to determine the root cause of procurement delays, and QCDSM to evaluate overall improvements. The study was conducted in the Procurement Division (MNT) of PT Lautan Air Indonesia, with data analyzed quantitatively by comparing the percentage of delays before and after corrective actions. Result. The findings reveal that the root causes of delays are vendors not responding to purchase orders, lack of reminder features in SAP systems, and manual purchase order processing. After implementing corrective measures such as SAP-based monitoring, automated reminders, and automated delivery purchase orders, the delay rate decreased significantly from 23% to 9.99%. The QCDSM evaluation showed improvements in all dimensions: higher data quality, reduced idle costs, improved delivery reliability, reduced operational risk, and improved team morale. Conclusion. The integration of Lean, RCA, and QCDSM has proven to be an effective and comprehensive approach in reducing procurement delays. The study contributes to both academic and practical fields by filling research gaps in combining Lean and QCDSM for improved procurement performance, while providing a workable model for companies facing similar challenges in their supply chains

Abstract

Efisiensi operasional gudang dipengaruhi oleh kesesuaian tingkat pergerakan produk dengan lokasi penyimpanannya. Pada warehouse finish good PT TES, produk dengan frekuensi pergerakan tinggi masih ditempatkan jauh dari loading area sehingga meningkatkan jarak perpindahan material handling dan waktu persiapan pengiriman. Penelitian ini bertujuan merancang tata letak penyimpanan yang lebih efisien untuk mengurangi jarak tempuh dan waktu proses pengiriman. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan pengumpulan data melalui observasi, wawancara, dokumentasi, dan pengukuran langsung. Produk diklasifikasikan menggunakan metode ABC Classification berdasarkan frekuensi pergerakan menjadi kelas A, B, dan C, kemudian dirancang tata letak menggunakan metode Class Based Storage sesuai karakteristik pergerakannya. Evaluasi dilakukan dengan membandingkan tata letak eksisting dan usulan berdasarkan jarak tempuh material handling serta waktu ritase. Hasil penelitian menunjukkan bahwa produk kelas A (fast moving) dapat ditempatkan lebih dekat dengan area loading. Tata letak usulan menurunkan rata-rata jarak tempuh material handling dari 87,4 meter menjadi 56,2 meter (35,69%) dan waktu ritase dari 1.054 detik menjadi 801 detik (23,98%). Hasil ini menunjukkan bahwa kombinasi metode ABC Classification dan Class Based Storage efektif meningkatkan efisiensi operasional warehouse dan mendukung kelancaran distribusi produk.

Abstract

Penelitian ini bertujuan merancang sistem kontrol berbasis Internet of Things (IoT) pada tungku pemanas anti nyamuk elektrik untuk meningkatkan efisiensi energi, keamanan, dan kenyamanan pengguna. Perangkat konvensional saat ini masih bersifat manual, rentan overheating serta boros energi. Penelitian menggunakan pendekatan mixed-methods melalui observasi, wawancara, kuesioner, dan metode Quality Function Deployment (QFD) dengan House of Quality (HoQ). Hasil analisis menunjukkan bahwa keamanan produk dan kontrol jarak jauh melalui smartphone menjadi prioritas utama dengan Importance Rating tertinggi. Rekomendasi teknis meliputi penggunaan mikrokontroler ESP32, sensor suhu DHT22, relay proteksi serta aplikasi mobile untuk monitoring real-time serta timer otomatis. Penelitian ini diharapkan dapat menghasilkan prototipe tungku pemanas anti nyamuk yang lebih aman, efisien serta sesuai dengan kebutuhan masyarakat di era smart home.
