Abstract

This research aims to examine and analyze the influence of Zakat, Infaq and Alms (ZIS) and sharia banking financing on the economy in Indonesia, both in the short and long term. The data in this research is secondary time series data in the form of quarters from 2012 to 2022. The analysis in this research uses VAR/VECM estimation with independent variables namely Zakat, Infaq and Alms (ZIS) and sharia banking financing while the dependent variable is Gross Domestic Product (GDP) Indonesia. The VECM estimation results in this research show that in the short term Zakat, Infaq and Alms (ZIS) during the past 3 quarters had a positive and significant effect on Indonesia's Gross Domestic Product (GDP), then in the long term Zakat, Infaq and Alms (ZIS) during 1 quarter ago had a positive and significant impact on Indonesia's Gross Domestic Product (GDP). Meanwhile, sharia banking financing (IBF) in the short term did not have a significant effect on Indonesia's Gross Domestic Product (GDP), while in the long term sharia banking financing (IBF) 1 quarter ago had a positive and significant effect on Indonesia's Gross Domestic Product (GDP).

Abstract

Paiton Unit 1, 400 MW power plant, has been the subject of a detailed performance analysis utilizing modelling and simulation techniques employing GateCycle software. This study encompasses an evaluation of the impact of variations in main steam pressure, condenser pressure, and main steam temperature on key performance parameters, including thermal efficiency, heat rate, condenser duty, and power generation. The model underpinning this analysis was developed based on the heat balance scheme of Paiton Unit 1 PLTU, and its validity was confirmed through validation using operational data. The simulation results demonstrate that an increase in main steam pressure and temperature leads to enhanced thermal efficiency and output power of the plant, while an increase in condenser pressure results in reduced efficiency and net power generation. A decrease in condenser pressure increases the pressure difference between the turbine and condenser, thereby facilitating greater energy conversion to mechanical power. Heat rate analysis reveals that the heat rate value decreases with increasing main steam pressure and temperature and decreasing condenser pressure, indicating an increase in system efficiency. This study validates the hypothesis that optimization of key operational parameters at Paiton Unit 1 PLTU can enhance plant efficiency and reduce fuel consumption, thereby providing both technical and economic benefits.
