Abstract

Tujuan kegiatan ini adalah perhitungan efektifitas pemanfaatan alat berat pemeliharaan jalan Kereta Api (KA) dalam rangka meningkatkan pemeliharaan jalan KA dengan identifikasi dari permasalahan yaitu seberapa efektif penggunaan alat berat yang sudah dimiliki?. Metodologi yang digunakan dalam penyelesaian permasalah tersebut adalah metode kuantitatif menggunakan pendekatan OEE (Overall Equipment Effectiveness) sedangkan metode kualitatifnya menggunakan pendekatan THIO (Technoware, Humanware, Infoware dan Orgaware) dan pendekatan sebab akibat. Hasil dari perhitungan OEE  dari alat berat pemeliharaan jalan rel PT. KAI yaitu 50,05% dengan  Availability rata-rata = 77 %, Performance rata-rata = 65% dan Quality rata-rata = 100% (karena dinyatakan tidak ada pengulangan, artinya hasil pekerjaan semuanya dianggap memenuhi syarat) dari hasil yang didapat menunjukkan bahwa terdapat peluang untuk perbaikan terutama pada performance, kemudian pada availability. Namun pada kenyataannya kedua hal ini sangat terkait dengan kemampuan pemeliharaan (maintenance) dari alat-alat berat yang ada. Usia alat yang sudah cukup tua (rata-rata 19 tahun) berpotensi menurunkan kinerja mesin bila pemeliharaan kurang memadai. Hal ini tampak sudah terlihat dari menurunnya availability dan performance.

Abstract

In the operation of the unit whose successor does not use a hydraulic system, the role of the clutch is very important in transmitting power from the engine to the transmission. However, the clutch can only slip so that it can no longer function to forward power from the engine to the transmission. This can be caused by several things, including: wear on the clutch material, the presence of oil in the field of clutch surface, and spring damage to the clutch. On Scania P 124 CB 8x4 NZ 420 units this slip on clutch problem also occurs so research needs to be done to find the main cause. The method used in this study is to carry out checks and measurements and then the results are compared with the standard values that have been determined. The result shows that the cause of the slip on the clutch on the Scania P 124 CB 8x4 NZ 420 unit is 1) the presence of oil that wet the coupling surface is caused by a damaged seal shaft; 2) wear on clutch components namely clutch disc and pressure plate. To keep the seal shaft in good condition, regular and regular oil changes must be made and when the replacement of the seal shaft must be in accordance with the part number so that the possibility of the same problem can be reduced.

Abstract

Tujuan penelitian ini adalah membuat modifikasi konstruksi dies untuk meningkatkan kapasitas proses produksi lever comp brake pada PT XYZ yang bergerak dibidang manufaktur otomotif dan engineering. Komponen lever comp brake berfungsi sebagai pengunci handle rem belakang motor matik, biasanya terpasang pada bagian steering. Proses pembuatannya menggunakan mesin Press MC 45 TS. Selama ini dalam proses pembuatan lever comp brake berjalan dengan baik, namun apabila dilihat dari hasil produknya masih kurang effisien. Terutama dari konstruksi awal dies yang mengakibatkan gap pada skrap hasil pierch dan blank yang besar, yang pada akhirnya penggunaan material untuk komponen tersebut terlalu banyak dan membutuhkan waktu pengerjaan yang lama. Berdasarkan penelitian yang telah dilakukan di lapangan, dilakukan perubahan konstruksi dies untuk proses 1 jalur, perbaikan dengan membuatkan guide post yang lebih lebar, yaitu dengan menyesuaikan material untuk proses 2 jalur. Ukuran shearing dibuat lebih lebar, sehingga proses shearing lebih cepat sekitar 14 iris/lembar. Pengambilan material menjadi lebih effisien, karena hasil proses 2 jalur, ± 30 pcs baru ganti material. Data hasil evaluasi proses produksi rata-rata 72,860 pcs setelah dilakukan improvement diperoleh effisiensi sebesar ± 17,86 %.
