Abstract

Frekwensi kerusakan yang terjadi pada mesin packaging untuk bubuk kopi SMS Baron SVB- 150 di PT Santos Jaya Abadi yang memproduksi bubuk kopi dan kopi biji goreng cuk1.1p tinggi. Empat sistem utama yang sering mengalami kerusakan adalah sistem volumetric rotary, sistem roll film holder, drive system dan sistem horizontaJ sealer. Selama illi perbaikan dilakukan hru1ya dengru1 menggru1ti part yru1g msak, tanpa menganalisa apa yang menjadi penyebab kemsakan tersebut.
Untuk itu perlu dilakukan perbaik.an secara sistematis yaitu dengan menga11alisa penyebab kerusaka11 ,kemudia11 diranca11g perbaikan termasuk pembuatan komponen atau spare part. Metode yang tepat untuk menganalisa dan mengevaluasi hal diatas adalal1 "Root Cause Analysi(RCA)". Sedangkan untuk mengidentifikasi masalah yang telah terjadi dru1 mencegah masalah yang mungkin akan teljadi dalam desain digtmakan metode "Failure }.;/ode and Effect Ana~ysi s·(FM )" .
Setelah diketahui penyebab kerusakan mesin selruna ini, kemudian dilakukan pengembangan dcsain dan pembuatan prototype untuk menguji performanya. Hasil dari pengujian perfonna prototype ini diketahui bahwa pada kecepatan mesin 60 packlmenit selisih panjang pack tanpa koreksi eyemark antara 3 - 7 mm per pack ,selisih panjang pack dengan isi produk dengan koreksi eye mark antara 3 - 5 mm per pack dan penyimpaugau kestabilan berat produk sebesar 2,5 %. Dengan performa prototype seperti diatas, maka mesin yang dibasilkan dapat memenuhi flmgsinya serta diharapkan dapat berfungsi secara integrasi dalam proses produksi.

The frequency of disfuction that always happened to the packaging machine for coffee powder SMS Baron SVB- 150 in PT. Santos Jaya Abadi that produced coffee powder and fried coffee bean still high. Four main system often happened
disfuction are volumetric rotary system, roll film holder system, drive system and horizontal sealer system. For his time, the repairing that we can do only change the broken parts without analysing the caused of disfuction machine.
From that case we can do systematically repairing with analysing the cause of disfuction and redesign the sy tem including to build the component or the spare parts. The right method to analysing and evaluating for this problem is the Root Cause Analysis (RCA). For while to identification that happened and to avoid probability problems wiU happen at the design, we can use the failure Mode And Effect Analysis
(FMEA) method. After notice the caused of machine disfuction, the design of development and the prototype for the performance testing can build. The conclusion after performance testing at 60 ppm speed machine are length defferences of pack without eyemark correction is 3 mm tmtil 7 nm1 per pack, lenght defferences of pack with eyemark
correction is 3 mm until 5 mm per pack and the deviation the weight stabilization product 2.5% . With the prototype performance, the machine had been produced can find the functions and that hoped to fuction by integrated in the production process.
