The increasing need for fish causes problems related to production in the fisheries sector. In fisheries production all information related to (fishing ground) is well known, but on the other hand it is not easy to predict the amount of production due to unclear information. This is also related to the number of ships that make trips, the length (time) of the trip, the type of fishing gear, weather conditions, the quality of human resources, natural environmental factors, and others. The purpose of this study is to apply Grey forecasting model or GM (1,1) to predict fisheries production. Grey forecasting models are used to build forecast models with limited amounts of data with short-term forecasts that will produce accurate forecasts. This study employs the data of captured fish from 2010 to 2018 to analyze calculations using the GM model (1,1). The results showed that the Grey forecasting model or GM (1.1) produced accurate forecasts with an ARPE error value of 9.60% or the accuracy of the forecast model reached 90.39%.

Background: Patients with Marfan syndrome can experience acute aortic dissection 77% with type A and 23% with type B, and 64% suffer from an aneurysm.Case Description: A 45 year old female admitted to intensive care with chest pain onset since 1 day ago, ECG examination shows sinus rhythm with normal axis. Chest x-ray shows dilatation and elongation of aorta with aorta aneurysm suspected. MSCT scan of thoracal shows dilatation of ascending aorta – distal of left subclavian artery – aortic arch – descending aorta – the thoracoabdominal aorta – right and left common iliac artery. On blood examination, we found elevation of D-dimer (3570 µg/L). Patient was given beta-blockers to control heart rate 60 beats per minutes, CCB and ACE inhibitor was given to control systolic below 110 mmHg. After putting so much thought, patient was scheduled for TEVAR procedure.Conclusion: Patients with Marfan syndrome tend to have thoracic aortic aneurysms involving aortic root, ascending aorta, arch, and descending thoracic aorta. TEVAR is minimal invasive procedure and  have good outcome in patient with aortic dissection.
