Hosana Plastic is a company which producing plastic pocket. This Company always carry on maximal production result. To reach the target, fluency activity of production process is very needed. This matter influenced by machine condition. Plastic pocket machine of HDPE D45 (DT_4515) is a very vital part in production process activity in Hosana Plastic. So that this machine can functioned well, so necessary machine treatment system according to scheduled and regular. The problems in this company is machine oftentimes not regular, wait until machine in heavy damage condition up to can not operate, so that cause cost of Down Time. To overcome the problem proposed 8 planning of treatment by using Markov Chain Method, with preventive maintenance and corrective maintenance by using lower cost analysis. 8 planning of treatment are : 1.Corrective maintenance in state 3 and 4 (P1). 2.Corrective maintenance in state 2, 3 and 4 (P2). 3.Corrective maintenance in state 2 and 3 (P3). 4.Corrective maintenance in state 2 and 4 (P4). 5.Corrective maintenance in state 4 and Preventive maintenance in state 1 (P5). 6.Corrective maintenance in state 3 and Preventive maintenance in state 1 (P6). 7.Corrective maintenance in state 2 (P7). 8.Corrective maintenance in state 3 (P8). In beginning maintenance companies (P0) was done Corrective Maintenance if machine in Heavy Damage condition ( 4= 0,1403454), so that got cost of maintenance equal to Rp 50.111.440,-. From 8 treatment of planning is chosen the best planning maintenance that has lower maintenance cost, that is doing Corrective Maintenance if the machine in medium damage condition ( 3 = 0,001953), and Preventive Maintenance if the machine in good condition ( 1 = 0,9921875) (P6). So that got maintenance cost up to Rp 72.065,- To know saving cost of treatment machine is done by : Coct Of Beginning Maintenance ( P0) – Cost Of The Best Planning Maintenance (P6). So that got saving cost of machine maintenance up to Rp 7.954.145,- or demote the machine maintenance up to 99,1 %.
