Penentuan Sistem Kompensasi Berdasarkan Risk Assessment dan Performance Appraisal Karyawan (Studi Kasus: Petugas Operasional Pemadam Kebakaran Kota Padang)

Risk is a possibility of the occurrence that may affect the achievement of objectives. Risk can give positive or negative effect. One of the jobs that have a high risk is firefighter job. Furthermore, a firefighter who are disciplined, responsible, and good in team work, they must be given a reward for their motivation. Therefore, the compensation that they get is equal with the potential risk and working achievement. The compensation of the risk and achievement is included in the extra payment of dangerous work (hazard pay) and bonus based on working achievement of an employee (merit pay). Comparing to the old system, the compensation system will increase the firefighters' income from Rp 900.000 to Rp 1.297.280 every month. The addition will also increase the budget of Damkar from Rp 550.800.000 to Rp 793.935.156 every year

Aplikasi Penentuan Rute Distribusi LPG 3 Kg

PT IB. Sumberdaya Development is one of LPG agent partners of PT Pertamina. This company is assigned to distribute 3 kg LPG. The LPG shipment is carried out from Monday to Saturday. The shipment goes to 66 depots using agent vehicle which are registered in PT Pertamina. From the preliminary study, there were problems which related to the long-distance shipment, and the limitation of transportation and capacity.  In this research, the shipment routes of 3 kg LPG in PT IB is determined. Sumberdaya Development problems consist of the distance of the travel, the time of travel, and optimal transportation cost. Based on Clarke and Wright Savings Matrix algorithm, by considering the vehicle capacity, the distance can be minimized. The point of this algorithm is calculating the saving by measuring the available reduction of distance and time. It is done by linking the existing depots and making a route which is based on the largest saving value of the distance from the agent to the destination depot. Each route is optimized by WIN QSB software by using Branch and Bound method. A program to facilitate the determination of shipment routes by using PHP programming language is designed. The proposed route for the 3kg LPG shipment is 762.35km  with  33.58% saving, and the proposed time is 2929 minutes with 15.27% saving. The shipment schedule is designed from Monday to Saturday day to Saturday with each of 7 routes. This is better than the actual route used by the company
