Penelitian ini bertujuan untuk mengidentifikasi sistem penjadwalan produksi dan menganalisa perbandingan yang terjadi dengan adanya metode penjadwalan sequencing dan meningkatkan produktivitas pada tirta alam bata ringan kota tarakan. pada penelitian ini menggunakan pendekatan kuantitatif deskriptif dan data yang digunakan adalah data primer. berdasarkan hasil analisa dan perhitungan menggunakan metode sequencing yaitu fcfs (first come first served), spt (shortest processing time), lpt (longest processing time), dan edd (earliest due date) dapat diketahui bahwa perhitungan menggunakan metode spt (shortest processing time) mempunyai nilai keterlambatan yang paling rendah daripada metode lainnya, sehingga metode ini menjadi metode yang optimal untuk meningkatkan produktivitas bata ringan dimana pesanan dengan proses paling singkat akan didahulukan. kata kunci : sequencing, penjadwalan produksi, fcfs, spt, lpt, edd

This study aimed to identify the production scheduling system and analyze the comparison that occurred by the sequencing scheduling method and increase productivity at tirta alam bata ringan in tarakan city. this study used a descriptive quantitative approach and the data were primary data. based on te results of analysis and calculations using the sequencing method, namely fcfs (first come first served), spt (shortest processing time), lpt (longest processing time), and edd (earliest due date), it was obtained that the calculation by using the spt (shortest processing time) method had the lowest delay value than other methods. therefore, this method was the optimal method to increase the productivity of lightweight bricks where the orders with the shortest process were taken first. keywords: sequencing, production scheduling, fcfs, spt, lpt, edd
