Abstract

The purpose of this research is to analyze simultaneous relationship between the Investment Policy, Debt and Dividend of firms. The effect of Uncertainty and Sales Growth to Investment Policy, The effect of Asset Tangibility and Deficit Financing the Debt Policy and The effect of the Return On Asset (ROA) and Retained Earnings (RE) to the Dividend Policy of Property and Real Estate Firm listed on Indonesia Stock Exchange.Sample in this research were selected by using purposive sampling method with some criteria. The samples are 39 firm listed in Indonesia Stock Exchange 2011-2014 period. The statistic method that used in this research are descriptive analysis, classical assumption test (Normality test, Heteroscedasticity test, multicollinearity test, autocorrelarity test), simultaneous equation models analysis (Three Stage Least Squares), Hausman Test, hypothesis test (F-statistics Test, t-statistics test, and Coefficient of Determination Test).The results showed that The Investment Policy and Debt Policy have a negative and unrelated simultaneously, Investment Policy and Dividend Policy have a negative and unrelated simultaneously, Debt Policy and Dividend Policy have a negative and related simultaneously. Uncertainties have a negative and not significant to Investment Policy and Sales Growth have a positive and not significant to Investment Policy, Asset Tangibility have a positive and not significant to Debt Policy and Deficit Financing have a negative and significant to Debt Policy, Return on Assets (ROA) have a positive and significant to Dividend Policy and Retained Earnings (RE) have a positive and no significant to Dividend Policy.

Abstract

Developing a dedicated renewable energy hybrid system is a viable option for extending access to electrical energy in energy-rich rural areas. This study conducted a feasibility analysis of using a hybrid energy system, combining solar photovoltaic, wind, and biogas, to generate electricity and meet the energy needs of the rural area. West Waru Village is selected as the case study area for this research because it has abundant renewable energy sources. The Hybrid Optimization of Multiple Energy Resources (HOMER) tools is employed for modeling and optimizing the hybrid energy system, offering a comprehensive analysis encompassing technical, economic, and environmental aspects. Furthermore, the study's findings were further analyzed through a sensitivity analysis, considering unpredictable factors such as village load consumption, solar radiation, wind speed, and biomass availability. Additionally, the study’s results reveals that the renewable energy hybrid system can meet nearly 80% of the rural area's electrical energy requirements at a cost of $0.16 per kWh, resulting in the reduction of 8.4 million kg of carbon dioxide emissions. These findings can serve as a baseline for stakeholders in developing renewable energy systems in rural areas.
