Abstract

Model kolaborasi vendor – buyer untuk deterioration item pada skema pembayaran progresif adalah kenaikan pembayaran yang membesar oleh pemasok untuk productsdeliver hingga titik delivery tertentu. Pembeli harus membayar bunga penundaan apabila pembeli tidak membayar pada periode penundaan yang pertama, bunga akan meningkat pada periode penundaan yang kedua, dan seterusnya. Tujuan tugas akhir ini adalah untuk mengembangkan model kolaborasi  vendor – buyer untuk deterioration item pada skema pembayaran progresif.Pada tugas akhir ini, model kolaborasi diselesaikan dengan menggunakan metode genetic algorithm.Contoh numeric digunakan untuk mengilustrasikan model dan alaisa sensitivitas digunakan untuk meverifikasi model. Solusi dari model menunjukkan bahwa model kolaborasi lebih menguntungkan pihak pemasok karena, pembeli akan dipaksa untuk membeli dalam jumlah yang besar.

Abstract

PT. X merupakan perusahaan yang bergerak di bidang pembuatan keramik. Target kualitas keramik yang diharapkan PT. X adalah 95% pada produk kualitas A, namun saat ini pengendalian kualitas di lapangan hanya mencapai 92,8%. Peningkatan target kualitas A dapat ditingkatkan dengan mengevaluasi apakah pelaksanaan sistem pengendalian kualitas telah dilakukan dengan benar. Upaya yang dilakukan dalam pencapaian target produk kualitas A adalah dengan cara memperhatikan faktor – faktor yang berpengaruh di setiap proses produksi seperti kondisi mesin, penyetelan temperatur, dan ketepatan waktu proses. Inspeksi sampel dilakukan dengan membandingkan standar pengendalian kualitas yang dimiliki oleh perusahaan dengan fakta yang terjadi di lantai produksi. Hasil dari penelitian adalah dengan membuat sistem pengendalian proses yang menitik beratkan pada tahap – tahap produksi di setiap mesin, serta diberikan usulan perbaikan terhadap pengambilan sampel pada setiap inspeksi yang dilakukan. Perbaikan sampel dilakukan dengan mengubah waktu, jumlah dan kriteria penolakan sampel.

Abstract

PT Mulcindo Steel Industry is a company specialized in steel fabrication, service, forming products, hollow products, c-truss products, and galvanizing process. Defect’s percentages on c-truss, main runner, batten hat 28x17, metal runner, and mini furring are over 0,05% but the study will be focused on the highest percentage which is the c-truss with 0,11% defect percentage. DMAIC is used as a method to find problem’s root cause which is found by 5 why analysis. There were several suggestions which are product defective definitions, product quality characteristic socialization to employees, coil width checksheet monitoring, c-truss machine work instruction, straightening uncoiler to the machine. It is found that solution implementation can reduce the defect percentage in c-truss product to 0,073%. The result have been able to reduce the level of defect on the type of different “kupingan tidak sama”.

Abstract

This paper anlayze PT X warehouse system since some problems that are faced by the company such as full capacity warehouse, the absence of a inventory control system, and bad facility layout. The full capacity warehouse problem is solved by using capacity analysis, repayment of raw material analysis, and selling the clothes waste. The improvement of inventory control system is conducted by comparing periodic review system and economic order quantity, while for the raw materials placement problem is solved by grouping the raw material. A periodic review system is simulated to know the number of raw material savings. The simulation result shows that the number of the raw materials can be reduced as much as 7 percent, while the new raw material placement save 42 percent of traveling distance.

Abstract

Currently, PT. Adicitra Bhirawa wants to increase their production capacity from 120 truck boxes per month into 250 truck boxes per month. The increasing of production capacity is applied by changing their production system from the piecework production system into line production system. The line production system is more efficient than the piecework production system in terms of the worker productivity. Line production system is designed using two heuristic methods of line balancing, Kilbridge-Wester and Helgeson-Birnie. The result shows Kilbridge-Wester gives the better result with 15 workstations. The proposed line production system can achieve the production target and increase the monthly worker productivity from 5.7 truck boxes/worker to 11.9 truck boxes/worker. A proposed plant layout is applied in order to support the new line production system.

X wants to develop Hazard Identification Risk Assessment and Risk Control (HIRARC) in order to fulfill the requirement of OHSAS 18001:2007 application. The area covers in raw materials warehouse, production, and finished good warehouse.The preparation of HIRARC is divided into 3 stages which are hazard identification, risk assessment, and risk control. Hazard identification is performed based on interviews with the workers, the observations in the factory, and the historical data of accidents at PT. X. The result of the risk assessment shows 34% of activities is categorized as low risk, 58% of activities is categorized as moderate risk , 8% of activities is categorized as high risk and there is no activity in the category of extreme risk. Risk control will be performed on activities with moderate risk and high risk category. Based on the result, there are 4 potential hazards with high risk category, which are the sharpness of the material in the production area, shortness of breath due to workers are not wearing APD, shortness of breath due to the pungent smell from additives during the casting process, and the hook of the basket is fragile in the mixing process. Risk Control is undertaken by giving APD, safety sign, punishment, equipment maintenance, and make a special area for walking.

Abstract

Overall equipment effectiveness (OEE) is a performance measurement tool that can measure the production losses and identify improvement potential. PT Astra Otoparts Tbk. Adiwira Plastics Division (PT AO AWP) is a manufacturing company of automotive components made from plastic which always perform continuous improvement to increase productivity. The problem is the lack of OEE calculation standar prosedure for family mold usage in plastic injection machines. The other problem is the production data on the web which used to measure the performance of the production process can not show the actual condition of plastic injection machine. The cause of this problem are database system, shot per hour (SPH) system updates, and admin errors in data input. Error in production data can lead to errors in performance calculation result of production process as well as errors in set improvement point analysis. The OEE calculation result using production data from Laporan Hasil Produksi is 86%. the result of this calculation is analyzed to obtain the most influential factor and get the root causes for the decisions of improvement.
