Abstract

Heart disease is a general term for all diseases that attack the heart organ. Death from the heart at the H. Adam Malik Central General Hospital was recorded to have a fairly high number. The purpose of this study was to determine the use of the Poisson Ridge Regression (PRR) method on the results of the analysis of deaths from heart disease at H. Adam Malik Central General Hospital Medan. PRR is a method that is generally used to estimate the regression of count data, and is very sensitive to multicollinearity. In this study, PRR was used to analyze deaths from heart disease in the presence of multicollinearity cases. The result shows that the estimated parameter of the PRR model is slightly different from the estimation of the Poisson regression model where the estimated value of the variable for patients with heart failure (X1) = 0,030751, the estimated value for patients with congenital heart disease (X2) = -0,002125, the estimated value for patients with heart disease ischemia (X3) = -0, 003085 and the estimated value of hypertension sufferers (X4) = 0,009689. The conclusion is that of the four variables, two of which have a positive influence on death from heart disease, namely patients with heart failure and patients with hypertension. This means that the more people with heart failure and hypertension, the more deaths from heart disease.

Abstract

The actions of workers and the conditions of the work place greatly influence the occurrence of work accidents, where accidents that often occur in welding workshops are workers tripping over tools or materials in the welding area, ringing in their ears, inhaling welding fumes, hands being pinched, being hit by hot iron sparks, and so on. Data collection is carried out by direct interviews in order to obtain data from work processes, accidents that may occur and findings from direct observations and similar related research. In processing the data, after the analysis has been carried out, it can be calculated based on the level of risk in the form of a value. This research aims to reduce the risk of work accidents using the Hazard Identification and Risk Assessment method, where this method is to find out how to identify potential dangers that may arise in the area and assess the risks using a risk assessment matrix. In this research, qualitative analysis was carried out using an observational approach. Of the 7 workshop activities, namely dropping goods/materials using a crane, cutting materials, welding, plate rolling, smoothing weld marks (granding), sandblasting, and painting, there are 28 potential hazards which are classified into: 21 risks in the Low Risk category (75%), 3 risks in the Moderate category (11%), and 4 risks in the High category (14%). With a frequency level range of 1-5, the severity value range starts from 1-2 and the risk levels obtained are low, moderate and high.

Abstract

Many factors can cause poverty such as low income, health, education and the powerlessness or inability of certain people to be able to participate in development in their country. Education is one of the most influential aspects, especially for the development of human resources. Poverty can also be measured by the ability of the community to meet their basic needs or needs in the form of food and non-food. This study aims to determine how big the impact or influence of each independent variable on the dependent variable using panel data regression method consisting of cross section and time series. The panel data regression method with a fixed effect approach to the individual effects model has a result of R2 of 99,63% where the per capita expenditure variables for basic needs and school dropout rates are factors that have a significant effect on poverty in North Sumatra Province and the p-value results from the partial test (t-test) expeniture per capita for basic needs is 4,841 1,984 and the dropout rate is 3,733 1,984.
