ABSTRAKPenelitian ini bertujuan untuk menguji faktor-faktor yang berpengaruh terhadap pengungkapan emisi karbon. Faktor yang diuji di dalam penelitian ini meliputi ukuran perusahaan, profitabilitas, kompetisi, pertumbuhan, rasio utang pada ekuitas, dan reputasi Kantor Akuntan Publik. Metode yang digunakan untuk mengukur seberapa luas pengungkapan emisi karbon mengadopsi dari check list yang dikembangkan berdasarkan lembar permintaan yang diperoleh dari Carbon Disclosure Project (CDP). Sampel penelitian ini dipilih menggunakan purposive sampling dan terseleksi 19 perusahaan pemanufakturan yang lterdaftar di Bursa Efek Indonesia berturut-turut mulai dari tahun 2012-2013. Hasil penelitian ini menunjukan bahwa rasio utang pada ekuitas berpengaruh negatif signifikan pada pengungkapan emisi karbon, sementara faktor lainnya tidak berpengaruh signifikan.Kata kunci: Emisi Karbon, Gas Rumah Kaca, Pemanasan global, Pengungkapan Sukarela, Protokol kyoto.
ABSTRACT
PENDAHULUANKomitmen politik internasional yang telah disepakati secara universal di Rio de Janerio, Brazil, Juni 1992 telah menciptakan sebuah gagasan era ekonomi baru. Gagasan yang dibentuk melalui KTT Bumi (Earth Summit) tersebut bertujuan untuk mewujudkan konsep pembangunan ekonomi berkelanjutan yaitu pembangunan yang memenuhi kebutuhan generasi saat ini tanpa mengorbankan kepentingan generasi-generasi selanjutnya. Kesepakatan terhadap komitmen tersebut dilatarbelakangi oleh kesadaran bahwa pembangunan yang hanya berusaha mencapai pertumbuhan ekonomi setinggi-tingginya justru akan menghambat keberlanjutan pertumbuhan pembangunan itu sendiri. Seperti perubahan iklim dan pemanasan global dapat merusak material bahan baku akibat banjir, sistem distribusi terhambat akibat tanah longsor, dan berbagai kerusakan karena faktor lain yang terkait dengan rantai nilai (value chain) pendukung kelangsungan hidup perusahaan. Untuk mencegah kerugian ekonomi lebih besar, United Nation Framework Convention on Climate Change (UNFCCC) menciptakan sebuah amandemen Internasional yang dikenal dengan Protokol Kyoto. Protokol Kyoto merupakan sebuah konvensi internasional yang
Tebu merupakan tanaman industri penting di Indonesia. Produktivitas tanaman tebu menurun dari tahun ke tahun. Fakta menunjukkan bahwa varietas yang ditanam belum disesuaikan dengan tipologi lahan, sehingga diperlukan pemetaan tipologi lahan dan penataan varietas tanaman tebu yang disesuaikan dengan sinergi kesesuaian dengan tipologi wilayah. Tujuan dari penelitian ini adalah melakukan pemetaan tipologi lahan dan penataan varietas tanaman tebu berdasarkan tipe kemasakan varietas di Kecamatan Jatiroto, Kabupaten
This research is an experimental study that aims to examine the combination of cattle manure, humic acid, and mycorrhizae to increase mycorrhizal infections in the roots of chili plants in the Udipsamments soil in Puger District, Jember Regency, which was carried out in May-November 2018. The research design used was a factorial complete randomized block design with 3 factors that were repeated 3 times. The first factor is cattle manure (0 tons / ha, 10 tons / ha, 20 tons / ha), the second factor is humic acid (0 ppm / ha, 200 ppm / ha), and the third factor is mycorrhiza (0 g / plant , 30 g / plant). The results showed that the combination of cattle manure, humic acid, and mycorrhiza inoculants to chili plant roots was able to increase the root mycorrhizal infection of chili plants and increase the nutrients available in the soil by 191.84% for nitrogen and 392.93% for phosphorus.
Online learning is a learning system that uses internet media as a learning model. Implementation of online learning activities using various media such as Webex, Google Zoom, Google Meet. During COVID 19, online learning was needed for the continuity of the learning process. Online learning with Project-Based Learning (PBL) is a step to solve the problem of practical knowledge. The method in this research uses research and development (R&D). The research sample consisted of the control class and the experimental class. The division of the groups was carried out: (1) vocational education in Indonesia (2) Posttest was carried out to see the abilities in the experimental class and the control class (3) a basic test of students' initial knowledge. The population in this study were vocational students consisting of the practical course and the control class. The results showed that there were differences and improvements in student learning outcomes during the COVID 19 period.
Purpose -The purpose of this paper is to simulate the environmental cost reports preparation used to measure environmental performance in realizing eco-efficiency. Design/methodology/approach -This research uses a descriptive case study by using environmental cost detail data from 2011, 2012, 2013 and 2014. The research object is PT Industri Kereta Api (Persero) located in Madiun, East Java. Findings -The result of the research shows that PT INKA (Persero) has not specifically made environmental cost report. It is found that the percentage of total environmental cost to operational cost tends to increase; the cost which gives the biggest distribution of total environmental cost is the prevention cost. By 2014, the effect of environmental costs on operating costs tended to decrease and during 2012-2014 PT INKA successfully maintained the blue star PROPER and the absence of environmental pollution reports. Originality/value -PT INKA's environmental performance is still well controlled and since its inception in 2014 PT INKA has succeeded in realizing the concept of eco-efficiency.
