Land Surface Temperature (LST) assessment can explain temperature variation, which may be influenced by factors such as elevation, land cover, and the normalized difference vegetation index (NDVI). In this study, a multiple linear regression model of LST variation was constructed based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite, relating to the period, 2000-2018. The highest LST variation of nearly 1.3 °C/decade was found in savanna areas while the lowest variation was in the evergreen broadleaf forest and woody savanna, which experienced a decrease of 2.1 °C/decade. The overall mean change of LST was -0.4 °C/decade and the regression model with LST as the dependent variable and elevation, land cover type, and NVDI as independent variables produced an R square of 0.376. The variation in LST was different depending upon the NDVI.

Introduction: Fire cases increase in residential buildings because short circuits, at dormitories are mostly affected by human factors. X university dormitory building is a place for 24 hours of students’ activities with a lot of electricity consumption, bad behavior; overpowering extensions, and many flammable objects such as paper and furniture. Research objectives are to investigate the appropriateness and mapping needs of fire protection systems with regulations. Methods: The research is a semi quantitative analysis. Primary data is conducted with observations by using a checklist form that refers to the regulations and results of managers' interviews. The obtained data are categorized into good with suitability >79-100%, moderate ≥60%-79% and poor <60%. Result: The appropriateness of the active fire protection system is under 60% or in the poor category. The appropriateness of the fire extinguisher is 47.77%, the hydrant is 58.75%, the alarm is 18.75% and the heat detector is 35.90%. There is no sprinkler installation in the dormitory building and no commitment from the top management regarding occupational safety and health. Fire extinguisher’s need is 10 tubes per floor, the number of hydrants have been fulfilled, alarm requires an additional 1 unit on each floor and a heat detector requires a total of 114 units. Conclusion: The active fire protection system is still under 60% (poor category) and no maintenances. Based on the aforementioned mapping results, it needs to add the number of piece equipment according to the regulations and maintenance efforts.Keywords: active fire protection system, dormitory, mapping

COVID-19 had been a disaster in Indonesia. Moreover, it is needed a study to analyze the trend of this case. The objectives of this study were (1) to propose the model for predicting COVID-19 using exponential smoothing, autoregressive integrated moving average (ARIMA), neural network, and fuzzy time series and (2) to compare the performance for each model by using RMSE as evaluation tool. In this study, the splitting data is implemented by 3:1 ratio on train and test data set. The results show that the neural network has the smallest error, 772.46 for RMSE. It means that neural network perform better than other forecasting model. Once, the characteristic data had big impact to building forecasting model whether in classical or modern model.

Personal hygiene is useful in maintaining the health of workers. However, Personal Hygiene is considered less important for workers due to the knowledge and attitudes of workers' personal hygiene. One's knowledge will have a positive and negative impact on one's actions. Garbage becomes a source of various diseases if not managed properly. The purpose of this study was to analyze the personal hygiene behavior of waste disposal workers and the factors that influence behavior. The research method is qualitative with a descriptive approach, with a total of 10 informants. Data collection techniques were carried out by in-depth interviews and direct observation. The results of the research on the personal hygiene behavior of workers are very important, knowledge of workers regarding personal hygiene and occupational safety and health is very necessary, by paying more attention to and improving personal hygiene, by maintaining hand hygiene, feet, nails, hair hygiene and maintaining skin hygiene on a regular basis. completing sanitation facilities, increasing management support in the form of occupational safety and health supervision. Managers are expected to be able to apply Occupational Health and Safety and apply personal hygiene behavior in particular.
