Abstract

PKS ?XYZ? merupakan perusahaan yang bergerak di bidang pengolahan kelapa sawit. Produk yang dihasilkan adalah Crude Palm Oil (CPO) dan Palm Kernel Oil (PKO). Tujuan penelitian ini adalah menganalisa kehilangan minyak (oil losses) dan faktor-faktor penyebab dengan menggunakan metoda Statistical Process Control. Statistical Process Control adalah sekumpulan strategi, teknik, dan tindakan yang diambil oleh sebuah organisasi untuk memastikan bahwa strategi tersebut menghasilkan produk yang berkualitas atau menyediakan pelayanan yang berkualitas. Sampel terjadinya oil losses pada CPO yang diteliti adalah tandan kosong (tankos), biji (nut), ampas (fibre), dan sludge akhir. Berdasarkan Peta Kendali I-MR dapat disimpulkan bahwa kondisi keempat jenis oil losses CPO berada dalam batas kendali dan konsisten.  Sedangkan nilai Cpk dari total oil losses berada di luar batas kendali rata-rata proses, hal ini berarti CPO yang diproduksi telah memenuhi kebutuhan pelanggan, dengan total oil losses kurang dari batas maksimum yang ditetapkan oleh perusahaan yaitu 1,65%.

Abstract

PT. XYZ is one of some cigarette companies in Indonesia. In producing cigarette, the firm requires a material named ?etiket? which is produced by printing division for internal consumers of PT. XYZ. In order to produce ?etiket?, there are some wastes occurred. One of wastes occurred in printing division is product defects. This paper attempts to identify wastes in the division of printing using Lean Manufacturing approach by applying Value Stream Mapping (VSM) method. The results from cause root analysis found that the problems caused the defects in production process. It shows that the most wastes occurs in the printing division are product defect and waiting time. The product defects are caused because there is no standard applied in processing the product and poor inspections by management, while the causes of waiting time wastes is because of lack of carrier and no standard in each process. The recommendation can be suggested to the company are adding some carrier (product?s transporter), creating process standard in each process.

Abstract

PT. XYZ is a food and beverage company in Indonesia which produces many kinds of products with several different packing size since 1979. PT. XYZ always strives to improve production efficiency, especially in minimizing waste and loss that occur in every process of production. This study was conducted to calculate the Overall Equipment Effectiveness (OEE) of packaging machines at line 2 of PT. XYZ and identify the cause of the loss and waste that exist during production process. Overall Equipment Effectiveness (OEE) is a method to evaluate how effectively a manufacturing operation is utilized. The result of this research indicated that the OEE percentages of packaging machines both Weighing and SVB do not meet the company?s standards, which is 80 %. The main factor causing the declining value of OEE is machine availability and it is happened because the machine operator takes a long time to set up the machine.

Abstract

SERVQUAL is a service quality measurement model that is assumed to be widely applicable in every sector of service industry, yet research proves the opposite. Characteristic of customer in each segment can be a factor that causes differences in measurement model. According to that fact, this research is conducted to identify the difference of measurement model in each customer segment, especially in e-banking industry. Not only we identify the measurement model,  this research is done to confirm the relationship between 3 constructs as well, which are service quality, satisfaction, and loyalty. Several statistical method will be introduced here in relationship with segmentation process, measurement model identification, dan the three constructs' validation process. Segmentation process yields 2 customer segments which are people with high and moderate expectation to service quality. In the first segment, the measurement model consists of 4 quality dimensions, which are fullfilment, efficiency, assurance, and web design while there are 5 dimensions in the second segment which are fulfillment, responsiveness, information technology, assurance, and efficiency. There are also significant relationships among service quality, satisfaction, and loyalty.

Abstract

Penelitian dilakukan pada produk yang berupa alas kaki (sandal pria). Berdasarkan hasil observasi dapat diidentifikasi belum adanya upaya dari produsen/perajin alas kaki untuk melakukan penelusuran terhadap harapan dan keinginan konsumen akan produk alas kaki yang sesuai dengan perasaan psikologis konsumen. Di sisi lain kesadaran dan keinginan konsumen akan desain produk semakin meningkat. Penelitian ini berusaha untuk mengetahui citra atau harapan konsumen akan produk alas kaki yang berupa sandal pria melalui pendekatan emosional dan psikologis, sehingga dapat dilakukan perancangan dan pengembangan produk alas kaki yang sesuai dengan citra dan harapan mereka. Metode Kansei Engineering digunakan untuk memformulasikan rancangan produk alas kaki berdasarkan perasaan psikologis konsumen yang tercermin melalui kata kansei. Kuesioner yang digunakan pada metode Kansei Engineering ini adalah kuesioner elemen desain dan kuesioner semantic differential. Model Kano digunakan untuk memetakan atribut-atribut produk berdasarkan perfomansinya. Hasil akhir penelitian ini adalah dengan mengintegrasikan kedua metode tersebut sehingga diketahui bahwa desain yang sesuai dengan citra/image dan perasaan pskologis konsumen adalah desain dua kategori Kano, yaitu one-dimensional dan indifferent.
