Published: December 2020

Abstract
There are many benefits found in implementing QFD. This method sets the standards for planned design and quality, making the product competitive. This literature study aims to make an analysis and synthesis of existing knowledge related to the topic to be studied in order to find gaps for the research to be carried out. Deployment’s Quality Function is a structured approach to finding customers, understanding their needs and ensuring that their needs are met with product specifications. In QFD Phase I, it is used to translate customer needs into product design attributes which we will refer to as technical measures. QFD phase 1 (product planning) is also called The House of Quality. The output obtained in QFD Phase I is used as input for QFD Phase II, where this stage is used to translate important technical actions into part characteristics that are considered the most important to meet customer needs. This paper tries to see the extent to which the two methods are applied by analyzing several relevant journals. The author hopes that this paper can be used as a future reference for researchers in product design.

Abstract
Clinic X is one of the health clinics that located in Medan, which provides public health and social security facilities. Based on preliminary observations and generally applicable in some health clinics in Medan, there is a high arrival of inpatients at certain times, resulting in a large number of service queues. After being observed several times, the main cause is that there are many non-value added activities in the health service process. Therefore, it is necessary to minimize waste and improve the layout of facilities to speed up the service process and reduce patient waiting time. Lean service methods are used to identify wastes that affect servants processing time and improve processes. Systematic Layout Planning methods are used to redesign the proposed layout according to the repair process. The results show that the proposed layout is better than the actual layout in terms of processing time and total transfer moments. Total transfer moment of 64.49% reduces the proposed layout 1,935 meters/week to 687 meters/week. The processing time was reduced by 22.62% from 4271.8 seconds to 3304.67 seconds.

Abstract
The closed-loop supply chain has been identified as an efficient and effective strategy for sustainable practices in manufacturing companies. An evaluation is essential to achieve a successful closed-loop supply chain. This study aims to evaluate the closed-loop supply chain performance in the bottled water industry using a fuzzy rule-based system. A case study is conducted to PT X, a bottled water company in West Sumatra. The results show the overall closed-loop supply chain performance of PT X is at a fair level. Nine measures in the forward chain are at a good level. In contrast, one measure (i.e., product characteristics) is classified into a poor level. Based on the results, the company needs to conduct improvements related to product characteristics. In terms of the reverse chain, two measures (i.e., material features and supplier commitment) are at a fair level, while four measures are at a good level. The company has to pay more attention to material features and supplier commitment. Improvements to those measures can increase the reverse chain’s performance, which indirectly increases the overall performance of the closed-loop supply chain.

Published: December 2020

Abstract
User datagram protocol (UDP) is widely used to send real time data which is not sensitive to packet loss such as short period sensor data. Since UDP header provides checksum field, this field can be used for increasing the UDP performance, for instance, providing partial error check service such as in UDP-Lite. The checksum field can also be used for encryption key transfer for dynamic encryption system to provide more secured datagram. This paper examines UDP checksum usage for either error check or security key exchange. UDP-Lite works well for erroneous environment by suppressing packet loss up to 4%. But encryption key distribution may be a good option as it provides more secure data, mainly in lossless environment, where packet loss is less than 1%. For losses traffic tolerant, UDP is a good choice if low delay is desired.

Designing Inventory Models to Minimize Total Inventory Costs by Using Mixed Integer Linear Programming (MILP) in the Warehouse of MRO Materials
Authors: Kusuma R I , Hakim I M 
Published: December 2020

Abstract
In this study, the problem that happen in the object of research is the company’s target which is Inventory Turn Over. These problems occur because the companies tend to decide to store materials in large quantities so there is no potential for material shortages that can disrupt maintenance activities. However, the large amount of storage creates risks such as high holding costs and the risk of damage. One way to solve inventory management problems is to make efficient decisions on order quantity (Q) and message time (T) so that a minimum total inventory cost is obtained without hampering maintenance activities. To achieve that, the method used in this study is ABC classification to determine the material classification that needs to be prioritized and Mixed Integer Linear Programming (MILP) to get a minimum total inventory cost. From this research, it is known that there are 9 types of materials that fall into category A out of 150 types. In addition, the total quantity of order (Q) and order time (T) results of the model is able to minimize the total inventory cost to IDR127,610,000

Abstract
The process of production affects the quality of the products produced. Related to this, good quality control is needed to improve product quality. This quality control can be done by improving methods or production processes that reduce product quality. PT. QRS is one of the companies engaged in the manufacturing of zinc coated steel sheets. The problem in the company is to see if variation from the product can lead to additional cost or loss in the company. Based on these problems, it is necessary to calculate the losses due to variations in the dimensions of the product in which the company must pay to achieve the desired specifications. To find out the initial problem we can analyze with Taguchi’s Quality Loss Function. Based on calculations, it was found that the value of the process capability index for the long dimension obtained was Cp = 0,5556. From the calculation of the company’s loss data, it was obtained at Rp. 17.111.796/month.
