PT. CKA is a private industry engaged in the production of metal stamping parts, tools, and dies. In making this product, we used the concept of production based on orders. In the manufacturing process, operator performance is considered less than optimal due to waste. These products require high accuracy and a fixed duration so that the process does not produce defective or unfavorable products. PT. CKA is committed to maintaining product quality through consistent manufacturing practices. In practice, the Kwbf Arm Rear Brake Part is the product that most often shows manufacturing defects. The application of this research connects various activities, such as identifying factors that cause product damage and then analyzing the causes of product damage using Lean Six Sigma. This study intends to analyze the factors that cause defects using the Six Sigma approach with the DMAIC concept, then, through fishbone diagram analysis and 5W+1H, make a proposal based on the stabilized type. Implementation suggestions resulted in SOP adjustments, work systems, and additional tools. The results of the study show that the DPMO value is 5674, which means that for one million there is a possibility of 6190.75 possible defects in the product produced. Kwbf's Arm Rear Brake Part products have a sigma level of 4.03, with the highest percentage of defects found in Blunt Serration (32%), Spot Welding Points Not Centered (30%), and Scratch Materials (26%). After analysis, it can be concluded that the causes of defects are human factors, methods, machines, the environment, and tools.

Ketika sebuah mesin manufaktur mampu beroperasi tanpa henti untuk jangka waktu tertentu, beroperasi pada kecepatan yang telah ditentukan, dan menghasilkan produk yang memenuhi standar yang telah ditentukan, maka dikatakan mesin bekerja secara optimal. Penelitian ini bertujuan untuk menilai kelayakan mesin shearing sehingga perusahaan dapat memutuskan strategi perawatan mesin untuk mencegah downtime. Teknik Overall Equipment Effectiveness (OEE) digunakan dalam penelitian ini. Teknik ini dapat diterapkan dengan membagi output aktual dengan output maksimum yang mampu diproduksi oleh mesin atau peralatan dalam kondisi operasi yang ideal. Wawancara dengan perusahaan mengenai statistik downtime mesin dan pengamatan di tempat untuk menilai kelayakan mesin shearing dilakukan sebagai bagian dari prosedur pengumpulan data. Rata-rata angka OEE menurut analisis data adalah 68,98%, yang menunjukkan bahwa masih ada ruang untuk pengembangan bisnis untuk meningkatkan nilai kinerja mesin. Nilai OEE rata-rata yang rendah mungkin dipengaruhi oleh ketersediaan. Sedangkan komponen performance inilah yang berdampak pada tingginya nilai OEE.Kata Kunci: mesin, efektivitas, OEE, dan output

PT OSIN salah satu perusahaan yang menjalankan bisnis usaha di bidang manufaktur otomotif. Perusahaan menerapkan model produksi flow shop yang pola produksinya line to line secara seri menggunakan metode penjadwalan produksi First Come First Serve. Permasalahan pada metode FCFS dinilai belum cukup optimal dalam mengatasi pemenuhan permintaan produk yang tidak pasti, sehingga menyebabkan keterlambatan jadwal produksi yang berdampak pada aliran atau distribusi barang dan dapat menimbulkan makespan yang tinggi pada kegiatan produksi. Usulan perbaikan metode dilakukan untuk memperbaiki waktu penjadwalan produksi yang berfokus dalam meminimasi nilai makespan yang ada pada sistem urutan penjadwalan. Penelitian menggunakan pendekatan heuristik algoritma Campbell, Dudek, Smith (CDS) dalam mengatasi permasalahan penjadwalan. Metode CDS adalah metode heuristik penjadwalan produksi yang dikembangkan dari algoritma Johnson dalam memperoleh beberapa iterasi urutan dari 6 jenis proses pengerjaan pada work center yang bertujuan untuk menganalisis total waktu pada tiap proses pengerjaan (makespan). Perbandingan dari kedua metode tersebut menggunakan metode FCFS dengan mengurutkan penjadwalan sesuai dengan urutan waktu pemesanan di awal menghasilkan total makespan sebesar 2.408,75 menit, sedangkan penggunaan algoritma CDS yang menggunakan 5 iterasi menghasilkan nilai makespan yang lebih kecil sebesar 881,3 menit. Dari kedua perbandingan metode didapatkan kesimpulan dengan menerapkan sistem penjadwalan dengan metode CDS dapat dijadikan sebagai usulan perbaikan kerja dalam mengatasi waktu keterlambatan pengiriman dan proses penjadwalan produksi.

PT OSIN is a company that runs a business in the automotive manufacturing sector. The company applies aflow shop production model whose production pattern is line to line in series using the First Come FirstServe production scheduling method. The problem with the FCFS method which is considered to have notreached the optimal enough in meeting uncertain product demands, causing delays in the productionschedule, which has an impact on the flow or distribution of goods and can lead to increased production inactivities. The proposed improvement method is made to optimize production scheduling, focusing onminimizing the makespan values in the scheduling system's order. This study uses a heuristic approach tothe Campbell, Dudek, Smith (CDS) algorithm in overcoming scheduling problems. The CDS method is aproduction scheduling heuristic method developed from the Johnson algorithm in obtaining severalsequences of 6 types of work processes at the work center which aims to analyze the total time for eachprocessing process (makespan). Comparing the two methods using the FCFS method by sorting thescheduling according to the order of the initial order time produces a total value of 2,408.75 minutes, whileusing the CDS algorithm which uses 5 iterations produces a minor matter of 881.3 minutes. Comparing theresults obtained by applying the scheduling system with the CDS method can be used as a proposedimprovement in overcoming the delay in delivery and the production scheduling process.

This study examines the extent to which five variables motivation, work discipline, operational environment conditions, training quality, and compensation schemes influence employee performance at PT RST. The research approach uses a quantitative methodology with a questionnaire instrument, which was distributed to 39 staff in the Stamping Operation Department. Data analysis was conducted through multiple linear regression to measure the influence of each variable and their collective contribution to employee performance. The results of the simultaneous analysis show that the five factors together have a very high explanatory power for performance variations, evidenced by a coefficient of determination (R²) value of 0.994. Partially, each factor motivation, discipline, work environment, training, and compensation shows a positive and significant influence on employee productivity. These findings emphasize the importance of designing data-oriented human resource management policies, where increasing motivation, enforcing discipline, improving work facilities, organizing regular training, and a fair and transparent compensation system are the main pillars in efforts to improve organizational efficiency and output. Keywords : Work Discipline, Work Environment, Employee Motivation, Employee Training, Compensation System
