Abstract

In industrial sector activities, supply chain processes involve extracting and exploiting natural resources that may hurt the environment. Based on this, an approach to supply chains that is more environmentally friendly is needed. Green supply chain management (GSCM) integrates environmental thinking into supply chain management, including product design, material sourcing and selection, manufacturing processes, final delivery of products to consumers, and end-of-life management after the last utilization period. PT. Putra Multi Cipta Teknikindo is a company engaged in the trade of goods and services. Trade in goods and services includes batik stoves, small industrial production machines, industrial and laboratory scale measuring and detection equipment, and batik workshops. The purpose of this study is to measure the performance of GSCM in PT. PMC Teknikindo. This research is expected to provide information on the company's performance conditions in applying GSCM. The company is expected to be responsive to this performance measurement to increase the performance of related indicators so that there is continuous improvement. GSCM performance measurement uses the Plan, Do, Check, Action (PDCA) approach with Analytical Network Process (ANP), Objective Matrix (OMAX), and Traffic Light System (TSL) methods. The results of this study are the total KPI value of 4,867 which means the GSCM performance of PT. PMC Teknikindo has not reached the target. The results of the performance measurement indicators contained 26 KPIs in the yellow category, 5 KPIs in the red category, and 1 KPI in the green category.

Abstract

PT KTS is a company in the beverage industry that has three product brands, namely Latoya, Daxu and Banew. The research focuses on Latoya products, because the largest contributor to assets is 70 percent. Inventory planning is done very simply by forecasting based on sales history data at PT KTS to retail, causing a buildup of finished goods in the central warehouse. PT KTS forecasts demand based on retail demand not based on final customer demand to retail. Inventories made are not based on sales to final consumers, resulting in a bullwhip effect. The method used is by applying the Distribution Requirement Planning (DRP), the goal is to calculate the value of BE at PT KTS, BE after DRP and make an order plan based on DRP. The calculation results give a value (BE) before DRP, namely 1,105 retail BJ Home, 4,36 retail Pak Anton, 0,745 retail Bu Ayu, 1,363 retail Depot S.R, 0,903 retail Bu Viska and 0,829 Dadi stores.

Abstract

Salah satu kendala yang masih sering dijumpai dalam sistem distribusi produk adalah adanya fenomena Bullwhip Effect yaitu adanya simpangan yang jauh antara persediaan yang ada dengan permintaan. Hal ini disebabkan kesalahan interpertasi data permintaan dan sistem informasi yang kurang terintegrasi di tiap rantai distribusi. Hal itu juga yang dialami oleh PT. Mondrian yang memproduksi produk pakaian jadi. Untuk melakukan perbaikan digunakan pendekatan Supply Chain Management (SCM), dimana didalamnya tidak hanya membahas tentang distribusi produk saja, tetapi juga mengenai persediaan dan sistem informasi yang penerapan SCM. Adapun tujuan penelitian ini untuk menganalisis Bullwhip Effect dan memenimalisasi total biaya persediaan dengan metode Continous Review. Hasil perhitungan nilai variabilitas menunjukan terjadinya bullwhip effect hampir disemua produk yang dikrimkan ke retailer-retailer. Kecuali pada produk sekido untuk retailer Sri Ratu Peterongan Semarang , produk sekido untuk retailer Sri Ratu Pemuda Semarang dan produk begaya untuk retailer Mirota Kampus Yogyakarta. Karena masing-masing Retailer tersebut memiliki nilai variansi permintaan sebesar 1,28; 1,65; 1,45; yang berarti lebih besar dari nilai perbandingan antara fungsi periode dan lead time sebesar 1,18. Dari hasil pengolahan data inventory dengan metode sistem Q, diperoleh iterasi terbaik pada iterasi 1 untuk produk Dadung dengan total biaya persediaan Rp. 39.638.737,53. Sedangkan untuk produk Begaya iterasi terbaik pada iterasi 3 dengan total biaya persediaan Rp. 27.924.118,81 dan untuk produk Sekido iterasi terbaik pada iterasi 2 dengan total biaya persediaan sebesar Rp. 52.328.084,57.

Abstract

Putat Wetan is one of the Kapanewonan Wonosari in Gunungkidul, Yogyakarta. It is a tropical area with many kinds of plants. Candlenut plants (Aleurites moluccana) thrive in the Putat Wetan area. So far, hazelnut fruit is only used as a spice in the kitchen, while the fruit is veru much. So that it is necessary to develop a candlenut processing into a product with a high selling value. One of them is made of hazelnut oil. There are various methods for making hazelnut oil, one of which has been practiced at Putat Wetan. The training for making hazelnut oil is carried out by taking the coconut milk and then heating it so that it will release the oil by itself. Coconut milk is taken by blending and adding water to take all the coconut milk in the candlenut. The results obtained from 250 grams of hazelnut fruit will produce approximately 45 ml of hazelnut oil. Keywords: Candlenut Fruit, Candlenut Oil, Putat Wetan, Warming Up.

Abstract

Industry player, navigates the competitive convection business by strategically selecting raw material suppliers, with a focus on fabric. Employing the Analytical Hierarchy Process (AHP), a decision analysis method by Thomas L. Saaty, the company evaluates criteria such as price, quality, delivery, service, and location. In parallel, the Analytic Network Process (ANP), a more intricate method by Saaty, is utilized to account for reciprocal relationships within decision-making hierarchies. The company evaluates three alternative fabric suppliers: Kumala Textile, PT Kaha Tex, and PT Ada Tex. AHP calculations assign priority values – Kumala Textile at 0.381187, PT Kaha Tex at 0.470966, and PT Ada Tex at 0.073924. Concurrently, ANP prioritizes alternatives differently: Kumala Textile at 0.315383, PT Kaha Tex at 0.565728, and PT Ada Tex at 0.118889. Considering the results, PT Kaha Tex emerges as the most optimal raw material supplier with a dual-method endorsement. Kumala Textile secures the second recommendation, while PT Ada Tex takes the third spot. Selection criteria for fabric raw material suppliers encompass price, quality, delivery, service, and location. Grounded in prioritization values and criterion relationships, the comprehensive recommendation is in favor of PT Kaha Tex as the most optimal fabric raw material supplier.
