Abstract. Identifying influential people as a node in a graph theory commonly calculated by social network analysis. The social network data has the user as node and edge as relation forming a friend relation graph. This research is conducting different meaning of every nodes relation in the social network. Ontology was perfect match science to describe the social network data as conceptual and domain. Ontology gives essential relationship in a social network more than a current graph. Ontology proposed as a standard for knowledge representation for the semantic web by World Wide Web Consortium. The formal data representation use Resource Description Framework (RDF) and Web Ontology Language (OWL) which is strategic for Open Knowledge-Based website data. Ontology used in the semantic description for a relationship in the social network, it is open to developing semantic based relationship ontology by adding and modifying various and different relationship to have influential people as a conclusion. This research proposes a model using OWL and RDF for influential people identification in the social network. The study use degree centrality, betweenness centrality, and closeness centrality measurement for data validation. As a conclusion, influential people identification in Facebook can use proposed Ontology model in the Group, Photos, Photo Tag, Friends, Events and Works data.

The research was motivated by the demands of the increasing government revenues, especially in the sector of taxation, both form all repair and fundamental change in all aspects of taxation. One of them is the demans on taxpayer compliance. Taxpayer compliance in implementing the tax obligations can not be separated from the role of the tax administration system that has been determined by the government and also the attitude of the public taxpayer itself. In addition, one of the efforts that are not less important is the government's efforts in improving taxpayer satisfaction through improved quality of service performed by the tax authorities which is expected to have an impact on taxpayer compliance. This study aims to determine the effect of the tax administration and the quality of service performed by tax authorities to taxpayer compliance is mediated by the behavior of taxpayer. This research is explanatory reseach using a quantitative approach. This data using primary data sources are derived from filling the questionnaire and interviews whit taxpayer that registered in tax office south Malang and assisted with a variety of relevant secondary data. Data were collected using accidental sampling method and analyzed by using path analysis in SPSS version 20. The results showed that both the tax administration, the quality of service performed by the tax authorities, and the behavior of taxpayer directly have a significant impact on taxpayer compliance. The results also show that the tax administration and the the quality of service performed by the tax authorities has a significant effect when mediated through the behavior of taxpayer. Therefore, based on the reseach that has been done, then all hypotheses that have been constructed in this study is acceptable. Various limitations faced by researchers is expected to become a challenge for future research to obtain reseach results further illustrate the factor that influence the increase taxpayer compliance.

Patients with diabetes mellitus (DM) with poor glycemic control have risk to a developing DM complications one of which is diabetic nephropathy, to establish the diagnosis of diabetic nephropathy, a test of creatinine serum should be conducted, and to see the glycemic control, a test of HbA1c should be conducted. The research aims to characteristics of the examination result creatinine serum in patients with DM terms of the results of HbA1c test, cross-section research design, there are 71 sample qualified the criteria for inclusion research. Sample collection and inspection are held in the Clinical Pathology Laboratory of the Hasanuddin University Hospital Makassar from May until June 2022. The results show for the examination results HbA1c with the most uncontrolled categories as much 63 people (88.7%) and only 8 people in the controlled category (11.3%), for result serum creatinine at most normal 34 people (47.9%) decreased by 25 people (35.2%), and increased by 12 people (16.9%), the research results were processed using the chi-square test to see the corelation between each variable. There is a significant correlation between the results of the examination of creatinine serum based on gender DM patients with a value of p=0.000 (p<0.05). There is no significant correlation between the results of creatinine serum examination with age classification in DM patients with a value of p=0.464 (p>0.05), and there is no significant correlation between the results of the creatinine serum examination in DM patients were reviewed from the results of HbA1c examination with a value of p=0.387 (p>0.05), so it can be concluded that serum creatinine can't be a major biomarker to see the presence of diabetic nephropathy in DM patients, it is necessary to add other biomarkers such as microalbumin examination, protein urine, glomerular filtration rate, and blood urea nitrogen for diabetic nephropathy in diabetic patients.
