OPTIMALISASI PERENCANAAN PENJADWALAN PRODUKSI BETON PADA PT JAYA ETIKA BETON

Manufacturing companies contribute significantly to economic development because they are able to produce goods or services. The production scheduling system in the precast concrete manufacturing industry at PT Jaya Etika Beton is not regularly coordinated so that production scheduling is not optimal and there are mismatches in due dates which cause delays in the completion process or product delivery. This research aims to analyze production scheduling planning through sequencing method calculations (job priority rules) focused on improving the smooth flow of the production process, customer loyalty and satisfaction. The analysis method for this research is qualitative and quantitative using the sequencing method.
The research results show that the most recommended, effective and efficient method that can be used by PT Jaya Etika Beton is the SPT (Shortest Processing Time) method through the principle of prioritizing jobs with the shortest processing time to be completed. The SPT method produces a total time flow of 364 days, an average completion time of 18 weeks, an average delay of 10 days, an average of 7 jobs and an average utilization matrix of 13%. So, by implementing the SPT method, companies can meet customer expectations regarding the speed of the product delivery process.
