North Sumatra known as bigger island with abundant of tropical tree species. Some of those were lesser known species. One of lesser-known and potential species from North Sumatera is Salagundi (Rhodoleia teysmanii). Despite being widely utilized by locals peoples, information on Salagundi’s population and other characteristics is very limited. The community in the surrounding area frequently uses wood for a variety of functions, such home construction. Excessive consumption potentially threatent the species’ existence in the habitat. Therefore, this study aims to determine the distribution pattern and population structure of Salagundi in Simorangkir Julu Village, Siatas Barita District, North Tapanuli Regency, North Sumatra Province. For those purpose, vegetation analysis techniques using a combination of plotted lines and lines were adopted. Result of this research showed that, distribution pattern of Salagundi at the seedling to tree level was clumped with the Morisita (Ip) index value of 0.51 -0.53. The population structure curve was the J-shaped reversed. This shows that the condition of the population is sustainable.

Health is one of the basic needs needed by everyone. Therefore, the government and community development should prioritize improving public health services. Hospitals in an area have an important role in community social services, especially health services. This research was conducted to assess hospitals' distribution and availability and analyze the quality and health services in Metro City. The 2SFCA method was used to determine the level of accessibility in Metro City. The accessibility value could assess the distribution and fulfillment of existing hospitals in Metro City and analyze the quality and health services there. The distribution of hospitals in Metro City showed that, on average, the hospitals are spread over areas with a high population density. The level of need and fulfillment of hospital facilities in Metro City is appropriate because hospitals are directly proportional to the number of residents. The 2SFCA results also showed a tendency for accessibility between hospitals and cities where accessibility is high in areas around hospitals, such as the Central Metro Area. However, in some cases, an area that has a good level of accessibility does not necessarily get good health services. Inadequate accessibility indicated that the fulfillment of hospitals in Metro City has not been fulfilled and is spread evenly in each region. With high accessibility and fulfillment, people can access health services better.
