Abstract

Kelongsoran terjadi di salah satu area strategis di daerah Tanjung Redeb. Di atas lereng terdapat menara Base Tranceiver Station (BTS) dan di bawah lereng terdapat workshop alat berat untuk perawatan dan fasilitas pertambangan. Berbagai alternatif rekayasa sipil untuk perkuatan lereng telah diaplikasikan, akan namun massa tanah lereng masih terus bergerak ke bawah sehingga lereng terus mengalami kelongsoran. Penelitian ini dilakukan untuk mengetahui nilai deformasi dan faktor keamanan jika dibangun dinding penahan tanah untuk memperbaiki kelongsoran lereng. Metode yang digunakan adalah pemodelan numerik dinding penahan tanah pasangan batu kali setinggi 18 meter dan panjang 38 meter dengan analisis metode elemen hingga menggunakan Plaxis. Hasil penelitian menunjukkan deformasi yang didapat adalah 0,01871 m pada tahap awal, 0,02604 m pada tahap galian, 0,02468 m pada tahap konstruksi, dan 0,02391 m pada tahap DPT sudah terpasang. Nilai faktor keamanan yang didapat pada PLAXIS adalah 4,493 pada tahap awal, 3,6 pada tahap galian, 3,362 pada tahap konstruksi dan 6,374 pada tahap DPT terpasang. Perbandingan faktor keamanan antara metode Bishop dan elemen hingga didapat perbedaan 1,313 % pada tahap awal, 1,22 % pada tahap galian, 0,982 % pada tahap kontruksi dan 1,764 % pada tahap DPT terpasang.

Abstract

This research tries to explore how Green Accounting can be used as a learning tool to strengthen environmental literacy in high school Economics lessons. This research uses a qualitative approach with a case study design. The research was conducted in a senior high school (SMA Negeri 2 Tanggul, Jember Regency) that has started to integrate environmental issues into the teaching-learning process. Data were collected through interviews with teachers, direct observation in the classroom, and analysis of learning documents such as lesson plans and student assignments. The results showed that when students learn accounting not only from the financial side, but also consider the social and environmental impacts of economic activities, they become more concerned and critical of sustainability issues. Teachers utilize project-based and contextual learning approaches so that students can relate theory to real problems around them, such as environmental pollution or waste management. This process helps students see that accounting is not just about numbers, but can also be a way to take care of the earth. This finding shows that economic education that promotes sustainability is not only possible in schools, but also very important to form a young generation that cares and is responsible for the future of their environment.
