Abstract

In order to  mitigate the impact of climate change  arising from Greenhouse Gas (GHG) emissions generated from the transportation sector, many countries  including Indonesia, have  initiated to develop policies to encourage environmentally friendly transportation technologies. Electric vehicles  represent a highly sustainable  alternative when compared to conventional vehicles. This study aims to  assess the potential reduction of GHG emissions from the shifting  to electric vehicle utilization on Java Island. The research method was conducted by modeling conventional vehicles until 2033 where there was a transition to electric vehicles throughout the model year and then calculating the GHG emission.  This study employs three scenarios : Business As Usual (BAU), Electric Vehicle Plan (EVP) with existing scenario power plant and Electric Vehicle Plan (EVP) with National Energy Plan (NEP) scenario power plant.  Model results revealed potential GHG emission reductions within 12.11% from the Existing EVP scenario and 12.54% from the NEP scenario against the BAU scenario  due to the shifting usege of electric vehicles on Java island. Based on the model results, it is possible to determine that shifting from conventional vehicles to electric vehicles can reduce GHG emissions from conventional vehicle use.

Abstract

Hazardous and Toxic Waste (B3) is a significant contributor to environmental pollution and requires proper management in accordance with regulatory standards. In vocational education, particularly automotive programs at Vocational High Schools, workshop activities commonly generate B3 waste such as used oil, batteries, and chemical containers. To address this issue, the Environmental Engineering Study Program of Universitas Bhayangkara Jakarta Raya conducted a community service program at Panca Bhakti Banjarnegara focused on B3 waste management. The activity was carried out through presentations and a Focus Group Discussion (FGD), covering the identification, temporary storage, and further handling of B3 waste based on Ministry of Environment and Forestry Regulation No. 6 of 2021 and Government Regulation No. 22 of 2021. The results showed an increase in participants’ understanding regarding regulatory obligations, proper storage practices, and the importance of preventing environmental pollution at the school scale. In conclusion, this program effectively strengthened knowledge and awareness of environmentally responsible practices, while laying the foundation for ongoing collaboration between the school and university. The program is expected to support the development of environmentally conscious graduates who are prepared to manage B3 waste responsibly in future industrial or automotive workplace settings.

Abstract

Latar Belakang: Perbedaan pandangan antara masyarakat dengan pemerintah dalam memandang pajak, pemerintah menganggap sebagai pendapatan sedangkan perusahaan menanggap sebagai beban. Perbedaan cara pandang pajak ini mengakibatkan tingginya kasus pajak di Indonesia. Agresivitas pajak ialah tindakan perusahaan untuk meminimalisi beban pajak dengan memanfaatkan aturan pajak.Tujuan: Penelitian bertujuan untuk menguji pengaruh likuiditas, leverage, dan Corporate Social Responbility terhadap agresivitas pajak dengan Corporate Governance sebagai variabel pemoderasi.Metode Penelitian: Data sekunder yang digunakan dalam penelitian ini berupa laporan keuangan perusahan sektor real estate dan properti yang terdaftar di Bursa Efek Indonesia pada tahun 2015-2019. Analisis data yang digunakan dalam penelitian ini menggunakan analisis regresi moderasi.Hasil Penelitian: Hasil penelitian menunjukan bahwa likuiditas dan Corporate Social Responbility tidak berpengaruh terhadap agresivitas pajak, leverage berpengaruh positif terhadap agresivitas pajak, corporate governance memperkuat pengaruh likuiditas dan leverage terhadap agresivitas pajak sedangkan corporate governance memperlemah pengaruh Corporate Social Responbility terhadap agresivitas pajak. Keterbatasan Penelitian:Hanya berfokus pada perusahaan real estate dan properti merupakan keterbatasan dari penelitian ini.Keaslian/Kebaruan Penelitian: Penelitian ini mereplikasi dari penelitian sebelumnya yang diuji kembali dengan menambahkan uji moderasi corporate governance.
