This unit facilitates health services in organizing blood donations, blood examinations, and blood distribution for patients. Currently, the management of blood distribution from the Blood Transfusion Unit to the hospital does not consider the optimal distance and route of blood distribution. In addition, this case study shows that 19 hospitals request types of blood to the Blood Transfusion Units. This study aims to determine the optimal route of blood distribution in the Blood Transfusion Unit. This study needs to solve the Vehicle Routing Problem by adopting the Sweep Algorithm to minimize the distance of blood distribution and determine the distribution route. Optimization of blood distribution found a reduction in the distance by 57% with a reduction in time of 58%. Further research is suggested to determine the scheduling of ordering blood requirements to obtain optimal results.

Currently, the number of halal certifications for SMEs in Indonesia is still limited. Problems in the halal supply chain need to be studied in order to facilitate and increase SMEs in obtaining halal certification. To overcome the gap of study, it is necessary to identify the barriers and drivers for SMEs in the implementation of the halal supply chain. The SCOR model was adopted in research to describe the activities of the business process and business actors involved in managing halal certificates. Then, there were 7 respondents who were interviewed including experts such as 2 auditors, 2 researchers, 1 policymaker and 2 food and beverage owners in one of the provinces in Indonesia. Thus, the study adopted a qualitative method by combining a case study approach and the literature review. The literature found that there are 11 barriers and 10 drivers ...

This shows that supply chain configuration in the palm oil industry is still not optimal. This paper contributes to measure value added of crude palm oil that is processed by palm oil downstream industry. Measuring was done using a simulated approach on supply chain configuration with integrating SCOR model and discrete event simulation. Finding in this research show the highest value added in distribution crude palm oil is scenario IV, which it is more valuable if palm oil downstream industries are able to produce finish product to the end customer. Furthermore, the simulation results can construct supply chain configuration in order to support decision-making process.

The virus is also known as an infectious disease inherited from a novel coronavirus. This study exposed the beginning of the unprecedented COVID-19 confirmed cases spike exponentially in the United States and 200 countries globally. Epidemiologists usually utilize conventional spread prediction via the classic clustering method. A suspected patient is likely to blow out the disease to a potential agglomerative of cases grouped in place and time. In the era of cutting edge, outbreak prediction can also generate accurate techniques to utilize unsupervised machine learning methods. We apply two prominent unsupervised learning methods, namely K-means clustering and correlation on a set Coronavirus Outbreak COVID-19 data collection dated March 27 and August 16, 2020.

Furthermore, this agency serves the community for the provision of information on the availability of blood, blood filtration of infectious diseases and blood storage. Problem of this case showed that there was out of stock of blood components that was caused by the blood components have low viability when long-time stored. Purpose of this study is to forecast demand of blood components for decision making process in supporting the activities of Blood Transfusion Unit. There were four methods of foresting involving moving average, weighted moving average, exponential smoothing, exponential smoothing with trend which these methods were analyzed using POM-QM software. Finding showed that there were two patterns of forecasting results of blood components that categorized into time series of stationary and trend. Implication in this study is able to select the appropriate forecasting method for anticipate the uncertainty demand of blood components. Further research is recommended to consider the safety stock for calculating the minimum inventory at Blood Transfusion Unit.
