Abstract

Nurses are the implementing elements of service activities of a hospital so that the quality of nurses will determine hospital performance. Therefore, nurses who have good performance are needed. Nurse performance is closely related to how much motivation and workload nurses have in providing health services to patients. Meanwhile, the number of nurses at the Makassar City Hospital is still inadequate, causing the nurses' workload to be quite high. However, in carrying out nursing care, nurses have their own motivations that encourage them to carry out their duties and responsibilities as well as possible. This study aims to determine the relationship between motivation and workload with the performance of nurses in the inpatient installation of Makassar City Hospital. The type of research used is quantitative research using a cross sectional study approach. The population in this study were all nurses who served in the inpatient installation of the Makassar City Hospital. Determination of the sample by the method of total sampling with a total sample of 69 nurses. The results of the study using chi-square showed that motivation (p=0.000) and workload (p=0.044). The p value of all independent variables <0.05 so that there is a relationship between motivation and workload with the performance of nurses in the inpatient installation of Makassar City Hospital.

Abstract

Tamanggung District is an area development that has characteristics of agricultural land use. The development of Tamanggung District indirectly has an influence on the population and the need for residential land. This sub-district is growing very fast due to strategic area conditions, good infrastructure, adequate facilities and easy accessibility. The creation of good infrastructure tends to have an impact on increasing activity and space density. The development of settlements in Tamanggung District occurs rapidly without being matched by an increase in basic service facilities. The development of settlements causes an increase in building density (building disinfection). The density of this building causes pressure on residential land and it is feared that it can exceed the carrying capacity limit. The purpose of this study is to calculate the carrying capacity of residential land in Tamanggung District and calculate the optimal population carrying capacity of settlements. The results of the study of the carrying capacity of residential land in Tamanggung District still have land large enough to accommodate the existing population of 4 (four) times the current population. Based on the provisions of the carrying capacity of land for settlements, the DDPm of Tamanggung District is included in the category of DDP> 1 which indicates that the Tamanggung District is able to accommodate residents to live. Based on the results obtained from the calculation of the carrying capacity of residential land in Tamanggung District, if the population increases 4 times from the current population, which is 319,024 people, the available land is still able to accommodate residents in the Tamanggung District area.The content of the abstract, between 150-200 words, just one paragraph.
