The concentration of CO2 gas in the air has continued to increase since before the industrial revolution until 2017. This condition is exacerbated by the reduction of Green Open Space (RTH) which serves as an absorber of gas CO2. Private green open space has the potential to be developed as a CO2 reduction (carbon sink) content in the air. The Coal Fire Power Plant (CFPP) XYZ has an area of 72 hectares with open space of 18 hectares. The purpose of this study is to analyze the amount of carbon sink from Green Open Space of CFPP XYZ and planning for reforestation through the approach of carbon sink potential. Methodology of this research using quantitative methods with calculate biomass of three. The results showed the potential for carbon sink from existing green open space of the CFPP XYZ was 1,082.79 Ton CO2 eqf/year or 77.34 eqf Ton/Ha/year and reforestation through the carbon sink potential approach produces a carbon sink capability of 20,825 Ton CO2 eqf/year.

Smart Government

Sustainable city is a city that designed by considering the impact on the environment, inhabited by population with a number and behavior that requires minimal support for energy, water and food from the outside, and produces less CO2, gas, air and water pollution. Moreover the national government envisions Indonesia2030which shallimplement the smart city towards sustainable development.Especially in Sleman Regency, the government is committed to make Sleman Regency as a Smart Regency in 2021. It could be shown in the vision of Sleman Regency which is The realization of a more prosperous Sleman community, Independent, Cultured and Integratede-governmentsystem to the Smart Regency in 2021”. This paper would like to analyze how the Sleman Regency implement the Smart city concept, and does the smart city concept can achive the sustainability city. The research uses the qualitative approach with in-deepth interview in examining the data, also the literature review. The result in this study reveals the following: firstly, from 2016-2019 Sleman regency has several applications to support the smart city implementation such as One Data of UMKM, Home Creative Sleman, Lapor Sleman app, Sleman Smart app, online tax app, e-patient, sleman emergency service, and Sleman smart room. Second, there are many elements in smart cities that are very important for smart government, smart life, smart economy, smart society, and smart environment. However, in supporting to support the realization of smart cities, not all aspects must be implemented properly to achieve a managed city, components related to smart environment cannot be implemented properly in Sleman Regency. There are still many problems regarding environmental problems such as the development of the construction of hotels and apartments that do not heed the environment, incrasing the populations, the limitations of green open space.

Funding Policies

This study aims to determine the effect of liquidity, funding policies, and financial performance on the stock prices of pharmaceutical companies listed on the Indonesia Stock Exchange (BEI) for the 2009-2018 period. The theory tested in this research is signaling theory. This research uses quantitative methods. The research variables are stock price, company liquidity, funding policy, and financial performance. The data used are secondary data taken from the Indonesia Stock Exchange (IDX). The population in this study is pharmaceutical companies listed on the Indonesia Stock Exchange. The research sample is 7 (seven) pharmaceutical companies listed on the Indonesia Stock Exchange (IDX) for the period 2009-2018. The results showed that company liquidity had no significant effect on stock prices, funding policies had no significant effect on stock prices, and financial performance had no significant effect on stock prices. The results of this study add to the outer layer of knowledge building according to Imre Lakatos. The implication of this research is that the company's fundamental conditions do not necessarily affect stock prices, depending on the type of stock market. It is recommended to investors to be more careful in observing the factors that influence stock prices in the 4.0 industrial revolution era. Next researchers are advised to use other fundamental aspects as their independent variables so that more fundamental elements of the company are examined in relation to stock prices in the 4.0 industrial revolution era.

This study shows how to measure CO2 emissions caused by railways during its life span from construction to disposal. It is now a common global concern that CO2 reduction is vital for conserving the global environment. Amidst this growing awareness, rail transport has attracted significant attention as an environmentally-friendly transportation mode due to its low emission of CO2 gas. But in many studies the amount of CO2 is calculated only during operation and doesn’t include emissions during the phase of construction of related infrastructure and rolling stocks. Rail transport can not be a truly environmentally-friendly transportation mode if it isn’t proven to emit less gases compared with other modes during a modes whole life cycle. In this paper, we introduce the method to calculate CO2 emission from the construction of infrastructure with the application of Life Cycle Assessment (LCA) and the result of a case study.
