Abstract

Efforts to conserve the environment must begin with small, tangible actions in one's immediate surroundings. Waste management is particularly critical, as every human activity has the potential to generate waste. Therefore, it is crucial to educate young children about the environmental impacts of waste to cultivate their awareness and concern for their environment. This community service initiative aims to enhance early childhood awareness of waste management's importance at KB-RA Masjid Jenderal Sudirman Surabaya through a comprehensive waste sorting program for organic and inorganic materials. The methodology employs a participatory approach, actively engaging children in learning activities. Evaluation involves conducting pre-tests and post-tests, which include giving children different kinds of organic and inorganic waste samples and assessing them to sort the waste into appropriate bins. Data is processed and analyzed using the paired sample T-test approach with Minitab software. The study's results indicate a significant increase in knowledge following educational sessions and assistance in sorting organic and inorganic waste. It is anticipated that this positive behavior will extend to their homes and communities, making waste sorting a concrete step towards mitigating environmental issues caused by waste

Abstract

This study aims to determine the effect of auditor choice, in this case Big-4 and Non-Big-4 Affiliated Auditors, on the Financial Reporting Quality in Banking Companies listed on the Indonesia Stock Exchange. The dependent variable in this study is Financial Reporting Quality with the proxy of Discretionary Accruals which are estimated using the Cross-Sectional Modified Jones Model. Meanwhile, the Independent Variable uses Big-4 or Non-Big-4 Auditor Choices. Hypothesis testing was carried out using Multiple Linear Regression analysis in 43 banking companies for 6 (six) years, namely 2016 – 2021. The test results show that the auditor choice has a negative effect on discretionary accruals. Thus, the auditor choice has an influence on the quality of financial statements.

Abstract

The mixture of hydrocarbon compounds in crude oil accounts for 90-95% of the oil's weight, while the remainder consists of non-hydrocarbons such as sulfur, oxygen, nitrogen, and metals. Sulfur in crude oil is removed due to its odor and corrosive properties. If this sulfur waste is not managed properly, it can have negative impacts on the environment. This research aims to analyze the compressive strength behavior of Sulfur Polymer Concrete (SPC) produced without a compaction process and Sulfur Polymer Concrete produced with a compaction process. SPC produced with a compaction process has a higher compressive strength than SPC produced without compaction. This is evident in the A3 variation, where the A3 variation produced with compaction has a compressive strength of 14 MPa, while the A3 variation produced without compaction has a compressive strength of 3.4 MPa. The similarity in the compressive strength of SPC produced without compaction and SPC produced with compaction lies in the pattern where the compressive strength reaches a saturation point. The addition of sulfur increases the compressive strength, and when it reaches its saturation point, the strength decreases with further addition because there is no more aggregate available to be bound, causing the sulfur to solidify.
