Parameter Case

Narwastu Firm is a company in Surabaya which produces traditional body care and aromatherapy. During the product distribution, this company encounters many mistakes such as inappropriateness between Purcashing Order (PO) from distributors/consumers and the goods delivered due to bullwhip effects. Therefore, this research aimed at reducing the bullwhip effects by implementing Collaborative, Planning, Forecasting, and Replenishment (CPFR) method and investigating a lot sizing technique for producing minimum distribution cost by Distribution Requirement Planning (DRP) method in order to regulate order and plan a certain distribution activity. The research results demonstrated that the bullwhip effect values after CPFR improvement of two products that could be repaired were 1.0 for Body Scrub Goats Milk Balibloom (BSC GM BB) 200 gr and 0.96 for Body Mist Sparkling White (BM SW) 60 ml. Meanwhile, the calculations by Distribution Requirement Planning (DRP) method with Economic Order Quantity (EOQ) method got the plans for ordering Body Scrub Lightening (BSC LIGHT) 200 gr by 182 times with total cost IDR 96,886,476 and Body Lotion Lightening (BL LIGHT) 250 ml by  235 times with total cost IDR 125,873,816.

PT. Pupuk Kaltim is biggest manure manufacturer in Indonesia, where its market area covering entire Sulawesi, Bali, some of Kalimantan East Java, Papua, Japan, Taiwan, India, and Australia. Main produced product of PT Pupuk Kaltim is based fertilizer. To meet the demand, PT Kaltim produce up to 2,3 million tons per year.Identifiaction process of supply chain done by accesing company website of PT Kaltim. Then it is outlined each step of supply chain from aggregate planning, production process, suppliers selection, quality mangement, warehousing, performance measure and used transportation unit. From that criteria would visible supply chain of based-fertilizer in PT Pupuk Kaltim. By having long and wide supply chain, PT Pupuk Kaltim still have bullwhip effect because of inacurate in forecasting cause over-stock or out of stock in many production period. In quality, PT Kaltim had got ISO 9001, ISO 14001 and ISO 17025 certification in production management and sea-port.Keywords: Fertilizer, supply chain, analysis

Remanufacturing processes face uncertainty in the quality of the items being returned by customers, this significant variability complicates the control of inventories. Demands can be satisfied by procured new items, but also by remanufactured returned items. This paper develops dynamic lot sizing model for remanufacturing industry under uncertainty of returned items and proposes Bayesian Inference to estimate the replacement ratio of returned items that used to determine those lot sizes for new items. The objective of this paper is to minimize the total cost composed of holding cost and set-ups cost. A numerical example is provided based on case study. The result shows that total cost is reduced to be 45%.

Q Model

PT. XYZ adalah perusahaan yang bergerak didalam pembuatan kemasan botol minum. Pendistribusian produk dilakukan PT XYZ menggunakan data historis berdasarkan jumlah permintaan pada tahun 2013 dan 2014. Data tersebut menunjukkan bahwa terjadinya perbedaan hasil. Tahun 2013 memiliki jumlah permintaan yang lebih rendah dari tahun 2014. Informasi terdapat bahwa perlu dilakukan pengevaluasian karena didalam rantai produksi terdapat bullwhip effect. Terdapat nilai bullwhip Effect menujukan bahwa nilai bullwhip effect untuk distributor Indomaret, Carrefour, dan rantai manufakturnya masing-masing sebesar 0,5303; 0,2967, dan 0,5114. Usulan perbaikan dapat diatasi yaitu dengan model Q yang berfungsi menggendalikan persediaan pada rantai pasok dengan metodeHadley-Within. Perhitungan pengendalian persediaan untuk distributor Indomaret, Carrefour, dan rantai manufakturnya masing-masing sebesar 1,0721; 1,100; dan 1,0714. Hasil dari perhitungan menujukan bahwa terjadi keseimbangan antara penjual dan pembeli sehingga biaya pun dapat dihematkan pada PT XYZ.   PT. XYZ Medan is manufacturing company that produce soft drinks of beverages in containers. In the product distribution system at PT. XYZ Medan, found that the number of orders based on the result of forecasting in 2013 lower than actual orders at distrbutor and manufacturer in 2014. Distorsion of information on this order can evaluate the indication of bullwhip effect in supply chain. Based on the result calculation of bullwhip effect, found that the value of bullwhip effect for Indomaret distributor, Carrefour, and supply chain of manufacturer each of 0,5303; 0,2967, and 0,5114. Proposed improvements to predominate bullwhip effect that is by doing inventory control policy with Q model using Hadley-Within approach. The value of bullwhip effect aftre doing inventory control policy for Indomaret distributor, Carrefour, and supply chain of manufacturer each of 1,0721; 1,100; dan 1,0714. The value of bullwhip effect which is close to one shows that the variance between the number of the order and the number of the demand nearly balanced so as to save the inventory cost at PT. XYZ Medan.

Research titled the SRG Supply Chain analysis (warehouse receipt system). This is the warehouse receipt, which is located in the village of the country's Bage Tango's Lopok district, Sumbawa District. Based on initial observation, there was no activity in the year 2018. Furthermore, the objectives that will be achieved in this research is the use of farmers on the farm and the concept of SRG and stakeholder view in the SRG. The research method used is interpretive with the type of phenomenology and analysis technique used by Sanders. With a sample of research is farmers who are in the area of Bage Tango and also in the area of the village of leverage, related stakeholders including the Agriculture service and management of the SRG. The result is that there are various obstacles that are not optimal utilization of the SRG, among them the transport factor of the harvest from paddy fields to the warehouse of receipt and lack of information about the SRG. Furthermore, there is the sustainability system of farmers ' lives of the grain exchange financing system as well as the continuity that is fixed in the speed and convenience of the sustainability of the farmer's life. Zero Stok's analysis of supply chains means that the warehouse does not accept farmers ' crops. Hence the proposed improvement of the chain in the delivery phase of agricultural commodities through Bumdes with the assistance of facilities from the local government.
