Abstract

Permasalahan: Industri sepeda motor di Indonesia terus mengalami pertumbuhan signifikan setiap tahunnya. Pada tahun 2024 hingga bulan Agustus, penjualan sepeda motor di Indonesia sendiri telah mencapai angka 4,34 juta unit. Perkembangan penggunaan kendaraan roda dua juga diiringi dengan perkembangan teknologi yang pesat di dunia otomotif, sehingga persaingan dalam pasar kendaraan roda dua juga semakin ketat. PT XYZ, sebagai salah satu perusahaan manufaktur sepeda motor di Indonesia, terus berusaha untuk berinovasi serta memenuhi kebutuhan konsumen. Dalam mewujudkan hal tersebut, salah satu upaya yang dilakukan oleh PT XYZ adalah dengan terus meningkatkan efisiensi bisnis proses internal mereka agar kualitas dari produk mereka selalu terjaga dan dapat bersaing dengan kompetitor-kompetitornya. Namun, beberapa bisnis proses internal pada PT XYZ masih memiliki banyak kendala, salah satunya adalah pada bisnis proses pengadaan barang. Proses ini masih menghadapi berbagai kendala yang menyebabkan lead time yang lama dan menurunnya efisiensi serta akurasi persediaan.
Metode: Penelitian ini menggunakan pendekatan sistem dinamik untuk memodelkan proses pengadaan barang yang kompleks. Dua variabel utama yang digunakan adalah lead time proses pengadaan barang dan efisiensi proses pengadaan barang. Model dikembangkan berdasarkan kondisi aktual dan digunakan untuk mensimulasikan tiga skenario perbaikan: standarisasi proses, integrasi sistem, dan gabungan keduanya.
Hasil: Skenario standarisasi proses meningkatkan nilai rata-rata efisiensi proses sebesar 4% namun tidak dapat menurunkan nilai rata-rata lead time proses. Skenario integrasi sistem menurunkan rata-rata lead time proses sebesar 10% dan meningkatkan nilai rata-rata efisiensi proses sebesar 6%. Skenario gabungan memberikan hasil paling optimal, dengan penurunan rata-rata lead time sebesar 9% dan peningkatan nilai rata-rata efisiensi proses sebesar 9%.

Problem: The motorcycle industry in Indonesia continues to experience significant growth every year. From January to August 2024, motorcycle sales in Indonesia alone reached 4.34 million units. The growth in the use of two-wheeled vehicles has been accompanied by rapid technological developments in the automotive world, resulting in increasingly fierce competition in the two-wheeled vehicle market. PT XYZ, as one of the motorcycle manufacturing companies in Indonesia, continues to strive for innovation and meet consumer needs. To achieve this, one of the efforts undertaken by PT XYZ is to continuously improve the efficiency of their internal business processes to ensure the quality of their products remains consistent and can compete with their competitors. However, some internal business processes at PT XYZ still face numerous challenges, one of which is the procurement process. This process is still plagued by various obstacles that result in prolonged lead times and reduced efficiency and accuracy in inventory management.
Method: This study employs a system dynamics approach to model the complex procurement process. Two main variables used are the procurement process lead time and the procurement process efficiency. The model was developed based on actual conditions and used to simulate three improvement scenarios: process standardization, system integration, and a combination of both.
Results: The process standardization scenario increased the average process efficiency value by 4% but did not reduce the average process lead time value. The system integration scenario reduced the average process lead time by 10% and increased the average process efficiency value by 6%. The combined scenario yielded the most optimal results, with a 9% reduction in average lead time and a 9% increase in the average process efficiency value.
