The sample of this research was taken by purposive sampling technique, the villagers of Pejaten who are tile craftsmen. Data was collected through a questionnaire filled with 105 tile craftsmen. The tile materials of Pejaten Village include clay and rocky soil, clay is currently almost 95% from outside the village of Pejaten. The clay supplier villages include Bantas Village, Selemadeg, Meliling, Jadi, Gadungan, and Pandak. Most of the coconut fiber fuel is mostly imported from Jembrana Regency. Some laborers in tile production are family members of craftsmen and most use wage labor. This condition shows the scarcity of tile production resources in Pejaten Village. This study aims to find out how tile production in Pejaten village is in a condition of limited resources, and how the forecasting model of tile production is based on historical data from January 2013 to December 2017. The results of in-depth interviews with several tile craftsmen state that they will continue to produce tile along the roof tile demand still exists and is able to provide raw materials even though most are imported from outside the Pejaten Village. The amount of tile production shows a seasonal trend, and the time series model that is most suitable for the number of tile production is the SARIMA (1,1,5) (1,1,1) 12 model.

Partial Least Square Regression (PLSR) is one of the methods applied in the estimation of multiple linear regression models when the ordinary least square method (OLS) can not be used. OLS generates an invalid model estimate when multicollinearity occurs or when the number of independent variables is greater than the number of data observations. In conditions that OLS can be applied in obtaining model estimation, want to know the performance of PLSR method. This study aims to determine the model of PLSR the influence of literacy rate, the average of school duration, school enrollment rate, Income per capita, and open unemployment rate to the level of poverty seen from the percentage of poor people in Indonesia by 2015. Estimated model with OLS , Only variable of literacy rate are included in the model with the coefficient of determination R2 = 32.52%. PLSR model estimation of cross-validation, leave-one-out method with one selected component has R2 of 33,23%. Both models shows a negative relationship between poverty and literacy rate. The higher literacy rate will reduce the poverty level, indicating that the success of the Indonesian government in the development of education will support the government's success in reducing poverty level.
