Abstract

In practice, most inventory system accommodate more than one type of item.Under this situation the analysis of inventory problem is approached by treating each type of item independently.The problem becomes complicated when constrains are imposed in inventory system.Constrains normally arise because scarce of resources exist such as capital,storage space, and equipment capacities. This paper considered a multi item inventory system with 2 constrains: working capital  and storage space restrictions.The Lagrangian method and The LIMIT technique  is utilized to obtain optimal order quantity solution for constraining conditions.While The Lagrangian method transforms a constrained optimization problem into an unconstrained  problem for higher dimension,The LIMIT Technique determines the relation of agggregate EOQ requirements to the limited resource available and revises all the lot sizes by the same proportion to bring the aggregate EOQ resources requirements within the limit. A case study of a multi item inventory system with constrains at PD Taru Martani Yogyakarta has been presented in this paper.   Keywords : multi item inventory system, constrains, the Lagrangian method, the LIMIT technique, optimal (economic) order quantity.

Abstract

To improve and maintain the reliability of PLTU X (FTP-1) power supply using coal fuel it is necessary to improve the reliability of the equipment especially on the crucial equipment which one of the pulverizer equipment for it is necessary to process the procurement of equipment components (stock warehouse) to maintain if possible a malfunction or malfunction occurs. The author intends to make three alternative procurement process that is through OEM procurement process, Non OEM / reverse engineering and recondition.This journal will analyze a financial feasibility study to ascertain whether the procurement has economic value and the asset will be used effectively and efficiently over the life of the benefit using the LCCA cost analysis approach. In this paper, historical data on pulverizer damage is obtained from the HDKP Rapsodi Settlement application to be verified and processed using minitab 17 applications to obtain the weibull shape factor (β) and scale factor / characteristic life () and the data as monte carlo simulation input. So we get mean time to failure (MTTF) / age of pulverizer component. To analyze the threealternatives and determine which alternatives are most profitable for 10 years with a life cycle cost analysis approach.Based on the analysis of quantitative calculation data, the life of pulverizer mills (MTTF) procurement process OEM for 10,108 hours / 1.2 years, non-OEM / reverse engineering for 16,899 hours / 2 years and recondition for 5,323 hours / 0.7 years and the results of approach life cycle cost analysis was obtained cost savings of 35.22 billion per unit pulverizer mills for 10 years with reverse engineering procurement process compared to OEM.

Abstract

Tujuan penelitian ini untuk mengidentifikasi, menganalisa dan memitigasi risiko berdasarkan KPI perusahaan untuk seluruh aktivitas perusahaan sehingga meningkatkan kinerja perusahaan dalam memberikan pelayanan pada klien kedepannya. Pada perusahaan jasa konsultasi di setiap aktifitas perusaaan akan rentang terhadap risiko sehingga dapat merugikan perusahaan dan hilangnya kepercayaan klien dalam menggunakan jasa konsultasi ini untuk selanjutnya.  Aktivitas perusahaan akan berjalan dengan baik jika manajemen risiko dilakukan dengan sebuah kerangka kerja untuk memudahkan dalam mengelola risiko. Metode penelitian dengan pendekatan ISO 31000 digunakan untuk mengidentifikasi, menganalisa dan memitigasi risiko. Ada 5 variable yang di teliti adalah strategi dan governance, proses bisnis, struktur, teknologi dan people. Hasil dari penelitian ini ada 40 jenis risiko yang teridentifikasi dari kuisioner yang dibagikan ke pihak perusahaan. Hasil dari mitigasi risiko yang dilakukan di perusahaan jasa konsultasi pada kelima variabel yakni perusahaan harus melakukan evaluasi secara rutin dari setiap devisi dan mitra kerja, memperjelas tugas dan tanggung jawab untuk setiap devisi dan karyawan, memberikan pelatihan- pelatihan kepada karyawan dalam masing masing bidang untuk meningkatkan kualitas pelayanan dan kinerja perusahaan.
