Abstract

Latar belakang: Penelitian ini membahas mengenai dampak penerapan sistem hybrid push/pull pada perusahaan produsen komponen otomotif yang menggunakan sistem produksi push pada proses produksinya. Hasil dari penelitian banyak ahli menunjukan bahwa dengan penetapan sistem produksi hybrid perusahaan bisa mendapatkan keuntungan dari dua tipe produksi yaitu sistem produksi push dan juga pull, serta dapat mengurangi kelemahan dari masing-masing sistem. Tujuan dari penelitian ini adalah untuk memberikan manfaat terhadap perbaikan sistem produksi dan menjadi pertimbangan terhadap perusahaan dalam optimalisasi terhadap proses produksinya. Perusahaan yang dijadikan objek penelitian adalah PT. Moreen JBBK, produsen komponen otomotif yang berlokasi di Jababeka, Cikarang, Jawa Barat. Metode: Analisis sistem produksi dan juga penerapan sistem produksi hybrid push/pull pada penelitian ini akan dilakukan dengan metode simulasi discrete event dengan menggunakan software simulasi Arena. Temuan: Teknik analisis statistik yang digunakan untuk pengujian hipotesis adalah Korelasi Pearson. Hasil penelitian menunjukkan bahwa ketangkasan belajar berkorelasi positif dengan perilaku kerja inovatif, r(537) = 0,61, p < 0,001.  Kesimpulan: Dari hasil penelitian ini diharapkan dapat menjadi acuan oleh universitas dalam mengembangkan program yang dapat membantu mengasah kemampuan learning agility sehingga meningkatkan kemampuan mahasiswa dalam berinovasi.

Abstract

​​​Background: The rapid development of the automotive industry requires an efficient production system to minimize costs and optimize resources. PT XYZ, an automotive component manufacturer, previously relied on a push production system based on demand forecasts. However, discrepancies between forecasted and actual demand led to excess inventory and increased storage costs. To address this issue, a hybrid push/pull production system was introduced, aiming to balance inventory levels while maintaining production efficiency. Methods: This study employs a discrete event simulation method using Arena software to analyze the impact of implementing a hybrid push/pull production system at PT XYZ. The research utilizes company data from October 2016 to compare the efficiency of different production scenarios. Findings:  Findings indicate that adopting a hybrid push/pull production system significantly reduces inventory costs while preventing backorders. The system modifies the upstream process by transitioning from forecast-based production to a pull system that aligns with actual demand. Meanwhile, the push system remains in use for raw materials and semi-finished components to ensure production continuity. Additionally, worker and machine utilization decreased, allowing the company to reallocate resources for other product lines, thereby enhancing production capacity. Conclusion: The study concludes that implementing a hybrid push/pull production system provides PT XYZ with a competitive advantage by reducing operational costs without compromising demand fulfillment. However, this system requires careful inventory tracking and employee adaptation. In the long run, reduced storage costs lead to substantial savings. Novelty/Originality of this article: The novelty of this research lies in its application of hybrid push/pull production to an SME automotive manufacturer in Indonesia, demonstrating its effectiveness in reducing costs and improving resource utilization.
