This study uses two estimation models, logistic and linear regression. The logit model is used to see the probability of an individual being a tobacco user. The second method uses multiple linear regres- sion which aims to see the factors that influence the demand for tobacco consumption in West Suma- tra. This research was obtained from National Socio-Economic Survey in 2019. Comparing these two models, there was a slight difference. Income does not influence an individual’s decision to become a tobacco user, while this variable is significant in influencing the demand for tobacco. This study also reveal that social and economic factors are significant in influencing the demand for tobacco in West Sumatra. Economic factors show that tobacco is a normal good. Meanwhile, from social factors such as education level shows that the lower the level of education causes individuals to become tobacco users and also causes the demand for cigarettes in West Sumatra to increase. This result causes the standard of household living to be disrupted because education is a human capital investment. So that various policies from the government are expected to control tobacco consumption in West Sumatra.

After the global financial crisis in 2008, economists believe that global economic conditions are a source of instability for the domestic economy in developing countries such as Indonesia. These external factors include fluctuations in global financial markets, volatility in commodity prices and capital inflows into the domestic economy which are known to have an impact on the financial cycle. This study explores the interaction of the three external factors to determine which factor has the most dominant interaction with the financial cycle in Indonesia. The interaction between external factors and the Indonesian financial cycle also means understanding the factors that affect the contraction period and expansion of the financial cycle in Indonesia. The study used time series data. The data used are secondary data from official publications, namely Bank Indonesia for data on capital flows and bank credit, the International Monetary Fund (IMF) for international commodity price index data and the global financial market valatility index (VIX). The analysis period in this research is 1993 first quarter to 2018 fourth quarter. This data sample selection is based on the availability of the longest data series using the quarterly data frequency in Indonesia. The result shows that shows that the interaction of total capital inflow to Indonesia has a pro-cyclical movement pattern with commodity price cycles and has a counter-cyclical movement pattern with the global financial cycle. Furthermore, the credit cycle to non-business fields is the cycle with the strongest interaction with all capital flow cycles analyzed in this study. Meanwhile, the total credit cycle and the credit cycle to the business field show a stronger procyclical interaction with the equity-based capital flow cycle than the interaction with the debt-based capital flow cycle

Pelatihan program zero waste diperlukan edukasi kepada semua  lapisan masyarakat untuk menumbuhkan kepedulian masyarakat terhadap lingkungan, sehingga masyarakat harus mengambil peran dalam pengurangan dan penanganan sampah.

Social welfare program from the government has a role in reducing poverty rates and improving the welfare of poor households. Through social assistance, it can increase household income and indirectly alleviate the need for women to work. This study aims to analyze the effect of government social assistance on the probability of married women participating in the labor market. This study uses secondary data from the National Socio-Economic Survey (SUSENAS) in 2019 in West Sumatra. Using the logit model, the results of this study show that married women who are receiving social assistance have a greater opportunity to participate in the labor market.

This study aims to analyse empirical studies regarding about the probability of women focusing on taking care of the household or remaining in the labour market after marriage. The method used in this research is descriptive method and explorative method from various literature reviews. Information obtained is related to economic, social, and demographic variables. A review of literature reviews shows variables such as children under five years of age, economic variables such as husband's income, education variables, women's working hours, and the area where women live affect the probability of women leaving the labour market after marriage.
