    There is a disparity in welfare between the people who dwell in mountanous areas and those living in plains, coastalal areas which is due to the difference in accessibility. Coastal regions, develop fast and generally have higher economic and social well-being because of the better accessibility they are bestowed with. However, in general, the people of Papua enjoy lower welfare than they are capable of enjoying in relation to the natural resopurces the province has. The abundant natural resources in the province have not been exploited to the full in endevor to improve the well being of the poptiakltuion. The division of Papua province into West Papua, Central Papua, and East Papua is expected to accelerate the development process, which should in turn reduce income disparity. None tbeless, some redress must be found to the problem of uneven distribution of natural resources among the three provinces, to prevent the emergence of regional paracholiasm which may the source of income inequality among the three new provinces due to their different respective locations on the the coast, plains, and mountaireous region.

    ABSTRACT A new rapid-test, sandwich immunochromatography assay technique has been recently introduced for the routine, rapid, qualitative detection of the presence hepatitis-B surface antigen (HBsAgl. To evaluate the sensitivity of rapid test, we studied 39 sera positive and one sera negative for HBsAg with conventional ELISA method. The study found that the minimal detectable level of HBsAg with rapid test was 4.03 ng/ml (range 3,25-4,03 ng/ml), it was 8 times less sensitive than conventional ELISA method (4,03 vs 0,47 ng/m1)⢠Many factors such as "eddy diffusion" and structure of HBsAg, humidity, direct contact with sunlight and sera of borderline-low level of HBsAg with conventional ELISA had a potency for lower sensitivity of rapid testconversely, technical factors such as adhesion, migration and viscosity of the samples do not. Key words : rapid test - dry chemistry hepatitis surface antigen (HBsAg) - sensitivity - ELISA

    Cases of diabetes mellitus (DM) in the world are increasing, Indonesia ranks fourth after India, China, and America. The most common DM is type 2 DM (T2DM), which is about 90%. The incidence of T2DM is caused by people’s lifestyles, which are influenced by socio-cultural factors. The highest risk of suffering from T2DM is prediabetes, which is a condition where a person’s blood glucose level is higher than normal but not high enough to be categorized as T2DM. This study aims to determine the socio-cultural influence on the lifestyle of prediabetes causing T2DM in the Bugis, Makassar, and Toraja tribes in South Sulawesi Province. The research design is qualitative with the rapid assessment procedure method. The population were prediabetics from biomedical samples in 7 regencies of South Sulawesi Province at the time of Riskesdas 2013. The samples were residents who are still prediabetes and T2DM in Jeneponto Regency (Makassar Tribe), Pare-Pare City (Bugis Tribe), and Tana Toraja Regency (Toraja Tribe). Information collection was carried out in 2017 through focus group discussions with two groups, non T2DM and T2DM. In-depth interviews with health program managers at the health office, puskesmas officers, health cadres, and community leaders. The study explains that there is a socio-cultural influence of prediabetes, ethnic groups in South Sulawesi Province in shaping the lifestyle that causes T2DM. Socio-cultural influences are the use of vehicles and the habit of doing activities in the Bugis, Makassar, and Toraja tribes.
