Abstract

This study aims to determine the optimal LPG gas distribution route where the distance traveled becomes closer so that it will minimize transportation costs and in terms of time make the distribution more efficient. The route uses the location of 7 bases that will be addressed by agents from PT XYZ in distributing LPG gas. This practical work took place from February to March 2024. The method used in relation to this route problem is Simulated Annealing where as iterations increase, the algorithm will tend to reject poor solutions. Thus, the graphical results will show a gradual decrease in fitness value towards a more optimal solution. The results of this practical work show that the use of the Simulated Annealing method is feasible in finding the optimal route. This method produces a final route with a distance of 50.8 km to 49.3 km with a travel route from PT XYZ- PG. Agus A LPG- PG. LPG Store Mr. Tri- PG. LPG Pertamina Bp. Didik- PG. LPG Budi- PG.

Abstract

. This study aims to evaluate the mental workload of employees at Dosare Hotel Yogyakarta using the NASA-TLX (National Aeronautics and Space Administration Task Load Index) method and propose an optimal work schedule. Dosare Hotel, operating with five employees across three shifts, faces challenges of excessive workload during periods of high guest occupancy. The study result show that employees with the highest NASA-TLX scores experience a high mental workload, while others fall into the moderate category. The proposed solutions include two scheduling options: hiring one permanent employee at a cost of IDR 15.000.000 per month or adding one outsourced worker at a cost of IDR 12.900.000 per month. This rescheduling is expected to improve work efficiency, maintain employee health, and minimize operational cost.
