Abstract

Procurement is a company activity in obtaining goods according to the specifications they need and meeting the criteria in the form of qualifications, requirements and regulatory rules related to the procurement of goods and services. PT X is a company affiliated with a state-owned enterprise operating in the sugar cane agro-industry sector that produces sweet soy sauce as their downstream product. In this object, researchers found a problem that the production of sweet soy sauce at PT X could not meet the needs of consumer demand due to the limited capacity of the sweet soy sauce cooking machine. Therefore, PT X procures a sweet soy sauce cooking machine with a limited tender auction system. The selection of supplier I (PT KM) and supplier II PT (TSE) which is a soy sauce production cooking machine supplier was selected using the Analytical Hierarchy Process (AHP) and Taguchi Loss Function methods. The results obtained from this study obtained that supplier II (PT TSE) is the best supplier with synthesis results weight of 0.747 or has a percentage of 74.7 as well as the results of Taguchi Loss Function calculations where supplier II fulfills all types of quality loss functions on each price subcriteria, namely on the price of the smaller better machine with a weight of 0.1228, the cost of insurance for the larger better machine with a weight of -0.0920, and the shipping cost of the smaller better with a weight value of 0.0294.

Abstract

The purpose of this study is to obtain a lightweight electric car frame design, providing a sense of security and comfort with the intention of being the basis for the placement of the steering, engine, battery, vehicle body, and other components for the needs of the Indonesian Electric Car Competition. This study was conducted using the Research Development method with the help of software that is capable of making a model in the form of a 3-dimensional image, in this case the software used is Solidwork software. Based on the results of the study, it can be concluded that: (1) Chassis design using Solidwork software with the design of KMLI competition needs before implementation (2) Car frame design with a 2000 watt BLDC motor specification with a 1/2 inch Black Iron Pipe frame material. (3) Analysis of the frame height when receiving a load of 100 kg is 16.5 cm with a chain ratio of 1500 rpm
