Abstract

Intangible Cultural Heritage (ICH) can effectively contribute to Sustainable Development Goals (SDGs) in all economic, social, and environmental dimensions, along with peace and security. Studying ICH in Indonesia cannot be separated from the spatial aspect of how an area's attributes are related to other areas located close to each other. Spatial regression modeling needs to be done by considering the selection of spatial weight matrix. Using the wrong spatial weight matrix will increase the standard error in parameter estimation. Therefore, this study aims to determine: the best spatial weight matrix to accommodate the spatial autocorrelation in analyzing the description of the spread of ICH in Indonesia; and the variables that are thought to influence the number of ICH determination in Indonesia. The spatial regression modeling used in this study is the Spatial Autoregressive (SAR) model and the spatial weight matrices compared in this study are queen contiguity and inverse distance. The best model is the SAR model used the queen contiguity spatial weight matrix because it has minimum values of AIC, BIC, RMSE and MAPE which are 310.397, 319.555, 18.857 and 57.169 respectively. Simultaneously, involved in performing arts, wearing traditional dress, knowing Indonesian folklore and the spatial lag contribute significantly to number of ICH determination in Indonesia. Partially, only knowing Indonesian folklore have a significant effect on number of ICH determination in Indonesia at significance level α=5%. Each additional 1% of population that knowing Indonesian folklore in an area increases number of ICH determination in that area by 0.6719 units .

Abstract

Family resilience is the family's ability to manage resources and problems to achieve prosperity as well as to survive and adapt to various conditions that are constantly changing, and have a variety of positive attitudes towards life's challenges. Family social and psychological resilience is one of the dimensions in family resilience, which is an important dimension in realizing a harmonious, safe and psychologically prosperous family. Kuta Alam District is an area of ??Banda Aceh City with the highest number of cases of the spread of Covid 19, for this reason, researchers want to examine the condition of family resilience in Kuta Alam District. The family resilience being studied is seen from the socio-psychological dimension. The approach of this research is descriptive quantitative by taking a sample of the location of several villages in the district of Kuta Alam, with a sample of 110 people. The method of data collection is in the form of a questionnaire. Overall, the condition of the family's psychological social resilience is in the moderate category. From the results of this study, it is suggested that families can cope with emotions positively by doing activities that they enjoy, increasing positive self-concept, establishing communication with family members and various covid-19 prevention programs from the central and regional governments aimed at families and must be implemented immediately. and right on target in order to restore the socio-psychological conditions of the community.
