Human Immunodeficiency Virus or HIV is still one of the most serious problems especially in developing countries. This study used HIV cases that recorded in Health Departement of Malang City, East Java, as one of the variables to determine the forecasting results using Exponential Smoothing. Goals from this study was for showed the results of forecasting with Exponential smoothing method’s that hoped could be a consideration to HIV prevention’s program.This study was a non reactive research using secondary data of male and female HIV cases from January 2012 to December 2016 as a variable that would show the results of forecasting. The result of forecasting with single exponential smoothing method on parameter value α=0.5 for male HIV cases and α = 0.6 for female HIV cases. The accuracy value in this forecasting can be seen on MAPE value at parameter α = 0.5 is 27.87 for male HIV cases and parameter α = 0.6 is 47.06 for female HIV cases. The results of the forecast could be concluded that in 2017 the number of HIV cases in man and woman were totally increased from the last years, need to arrange a suitable programs that which aim to resolve the problem.

Introduction: The number of chemicals is increasing every year. Laboratories record work accidents because there are several chemicals that are not labeled and unidentified but are stored in an inappropriate place. The Globally Harmonized System (GHS) is a Global System for standardizing criteria and harmonizing hazard classification systems, Safety Data Sheets (SDSs) and Labeling. This research aims to assess and evaluate the implementation of the GHS at the Occupational Safety Division of the Manpower and Transmigration Department Surabaya. Methods: This research was a descriptive observational study. Data were collected by assessing 80 types of chemicals through assessment sheets and an interview with the analyst supervisor, who had responsibility and authority in the application of the GHS. This research aims to apply the GHS with hazard classification variables, SDS availability and suitability, and labelling availability and suitability. Results: The results showed that the implementation of the GHS at the Occupational Safety Division of the Manpower and Transmigration Department Surabaya was 66.67%, categorized as good, with a good availability and suitability assessment of SDSs of 91%, and a good availability and appropriateness assessment of labelling of 98.1%. Conclusion: The results showed that the Occupational Safety Division of the Manpower and Transmigration Department Surabaya has been very good at implementing the GHS, but some points must be made to maintain and improve the application of the GHS as an effort to prevent accidents with hazard communication.
