Abstract

In 2010, Indonesia ranked fourth in terms of waste generation. As a result, the waste sector is estimated to potentially contribute 296 Mt CO2 eq (10.32%) of total greenhouse gas (GHG) emissions by 2030, with a projected annual growth rate of 6.3% using the business-as-usual (BAU) projection from 2010 to 2030. Around seventy per cent of all waste is organic, making household waste one of the main sources of urban waste. This study was conducted at the Benowo Landfill in the city of Surabaya. The SNI 19-3964-1994 method was used to sample the composition and generation of waste at the landfill. Waste generation projections were made up to 2030, taking into account population growth. This study compares methane gas emissions from three scenarios: Scenario 1, direct landfilling of waste; Scenario 2, waste reduction through composting and 3R processing; and Scenario 3, waste processing at the landfill through gasification. Based on inventory calculations using the 2006 IPCC guidelines, the landfill scenario produces the highest greenhouse gas emissions (CO2 and CH4), with the highest CH4 emissions and the lowest CO2 emissions. The gasification scenario has the highest CO2 emissions and the lowest CH4 emissions due to the use of aerobic systems and combustion.

Abstract

In this study, the impact of EPS, CR, ROE, and DY on the share prices of food and beverage companies listed on the Indonesia Stock Exchange (IDX) from 2019 to 2021 is being examined. The number of samples was selected using purposive sampling techniques. The data were Tanggal Revisi: analyzed to test multiple hypotheses using multiple linear regression analysis methods. 27 Maret 2023 According to the study's findings, DY's ROE and results have no impact on the stock price, but EPS and CR do have an impact on the share price. The share price of food and beverage Tanggal companies listed on the IDX was influenced by EPS, CR, ROE, and DY by 81.9%, according to 23 an R2 value of 0.819.
