Survival Analysis in Patients with Dengue Hemorrhagic Fever (DHF) Using Cox Proportional Hazard Regression

Indonesia is a tropical country that has two seasons: the rainy season and dry season. In the rainy season frequent flooding or puddles of water that could become mosquito breeding and the spread of various diseases, one of which is the dengue fever. Dengue Hemorrhagic Fever (DHF) is the cause of public health problems with a very rapid deployment and can lead to death within a short time. This causes dengue become one of the attractions to be investigated further. This study discusses the survival analysis and the factors that affect the healing rate of dengue patients using Cox proportional hazard regression based on data from the medical records of hospitalized dengue patients at the Jember Klinik Hospital. The results showed that the factors of age, gender, hemoglobin, trombonist, and hematocrit affect the healing rate of DHF patients

Identifying Supply Chain Performance of Organic Rice in Lampung

Lampung Province has organic rice fields which always increase with a planting area of 65.78 hectares. The problem of farmers is the limited access to the organic rice market. Products can't be sold at organic prices; some are still sold by farmers at non-organic prices. Organic rice supply chain networks need to be identified by farmers so that farmers have market information and supply chain performance. For this reason, this research purpose to analyze the supply chain of organic rice in Pringsewu Regency. Data analysis method uses the concept of supply chain performance with the Supply Chain Operations Reference (SCOR) approach. SCOR consists of five elements including flexibility, reliability, responsiveness, assets, and cost. The results of performance organic rice supply chains at all levels in the attributes of flexibility and responsiveness have achieved the superior performance position. The performance of organic rice supply chains attributes of asset at the farm level only achieves an advantage. But the supply chain performance in the attribute of reliability has not been able to reach a good performance position. So, there needs to be an improvement effort through disciplinary shipping arrangements and product quality improvements to improve supply chain performance
