Tujuan penelitian ini adalah untuk mengetahui: (i) biaya dan periode grease optimal yang digunakan untuk proses penggantian dan pemeliharaan bearing unit trailer di Sugar Group Companies, dan (ii) pengaruh periode grease, umur pakai bearing unit trailer, frekuensi penggantian bearing dalam setahun, frekuensi grease dalam satu tahun, unit bearing trailer, merk bearing trailer, dan lokasi pabrik berpengaruh terhadap biaya penggantian dan pemeliharaan bearing unit trailer di Sugar Group Companies. Metode dasar yang digunakan pada penelitian ini adalah deskriptif analitik. Metode penentuan lokasi dilakukan secara sengaja (purposive) yaitu Divisi Workshop Sugar Group Companies yang meliputi tiga pabrik, yaitu: PT. ILP, PT. SIL, dan PT. GPM. Metode analisis yang digunakan adalah berupa analisis tabel, grafik, dan analisis regresi berganda. Hasil penelitian menunjukkan bahwa periode grease biaya penggantian dan pemeliharaan bearing unit trailer di Sugar Group Companies yang optimal, untuk: (i) PT. ILP baik merk A maupun merk B untuk bearing unit trailer: Fertilizer Trailer, Water Tank, Side Tipping Trailer, dan Tangki Moving adalah periode grease 5 hari sedangkan bearing unit trailer Patria dan Disc Harrow pada periode grease 3 hari; (ii) PT. SIL baik merk A maupun merk B semua jenis bearing unit trailer yakni: Fertilizer Trailer, Water Tank, Patria, Side Tipping Trailer, dan Tangki Moving pada periode grease 5 hari kecuali bearing unit Disc Harrow pada periode grease 3 hari; dan (iii) PT. GPM untuk merk B semua jenis bearing unit trailer (Fertilizer Trailer, Water Tank, Patria, Side Tipping Trailer, Tangki Moving, dan Disc Harrow) pada periode grease 5 hari, begitu pula dengan merk A kecuali bearing unit Disc Harrow pada periode grease 3 hari. Selanjutnya, faktor-faktor yang berpengaruh terhadap biaya penggantian dan pemeliharaan bearing trailer di Sugar Group Companies adalah periode grease, frekuensi penggantian bearing dalam satu tahun, dan frekuensi grease dalam satu tahun. Selanjutnya, unit bearing Fertilizer Trailer memiliki biaya penggantian dan pemeliharaan bearing unit trailer paling rendah dibanding unit bearing trailer lainnya (Water Tank, Patria, Side Tipping Trailer, Tangki Moving, dan Disc Harrow). Merk A memiliki biaya penggantian dan pemeliharaan bearing unit trailer lebih rendah dibanding merk B. PT. ILP memiliki biaya penggantian dan pemeliharaan bearing unit trailer paling rendah dibanding PT. SIL dan PT. GPM (PT. GPM memiliki biaya penggantian dan pemeliharaan bearing trailer paling besar).

The purpose of this study was to determine: (i) the costs and periods of grease optimally used for the replacement and maintenance of the bearing unit trailer in Sugar Group Companies (SGC), and (ii) the effect of a period of grease, lifespan bearing unit trailer, the frequency of replacement of bearing in a year, frequency grease in one year, bearing unit trailer, trailer bearing the brand and type of plant affect the cost of replacement and maintenance of the bearing unit trailer in SGC. The basic method used in this research is descriptive and analytical. The method of determining the location of intentional (purposive) that Workshop Division SGC which includes three factories, namely: PT. ILP, PT. SIL, and PT. GPM. The analytical method used is in the form of analytical tables, charts, and multiple regression analysis. The results showed that the period grease bearing replacement costs and maintenance of the trailer unit in SGC are optimal, to: (i) PT. ILP both brand A and brand B for bearing unit trailer: Fertilizer Trailers, Water Tank, Side Tipping Trailer, and Tank Moving is a period of 5 days, while bearing grease trailer unit Patria and Disc Harrow on grease a 3 day period; (ii) PT. SIL both brand A and brand B all kinds of bearing unit trailer namely: Fertilizer Trailers, Water Tank, Patria, Side Tipping Trailer, and tanks moving in the period 5 days unless bearing grease trailer unit Disc Harrow on grease a 3 day period; and (iii) PT. GPM for brands and all kinds of bearing unit trailer (Fertilizer Trailers, Water Tank, Patria, Side Tipping Trailer, Tank Moving, and Disc Harrow) in the period from grease 5 days, nor with the brand A except bearing unit trailer Disc Harrow in the period grease 3 days. Furthermore, the factors of the cost replacement and maintenance trailer bearing in SGC is a period of grease, bearing replacement frequency in one year, and the frequency of grease in one year. Furthermore, Trailer Fertilizer bearing unit has a bearing replacement costs and maintenance of the trailer unit is lowest than the other trailer bearing unit (Water Tank, Patria, Side Tipping Trailer, Tank Moving, and Disc Harrow). Brand A has a bearing replacement costs and maintenance of the trailer unit is lower than brand B. PT. ILP has a bearing replacement costs and maintenance of the trailer unit lower than PT. SIL and PT. GPM (PT. GPM has spend the most cost for replacement and maintenance bearing trailer).
