Abstract

Penelitian ini bertujuan untuk mengetahui dan menganalisis debt to asset ratio, debt to equity ratio dan times interest earned pada PT Bank Central Asia Tbk tahun 2020-2022. Penelitian ini dilakukan melalui website resmi Bursa Efek Indonesia (BEI) di situs www.idx.co.id. Sumber data yang digunakan adalah data sekunder berupa laporan keuangan periode tahun 2020-2022. Teknik analisis data yang digunakan dalam penelitian ini teknik analisis deskriptif kualitatif yaitu data yang berupa angka-angka yang meliputi laporan keuangan berupa neraca dan laporan laba rugi yang menggambarkan keadaan atau peristiwa pada perusahaan secara nyata. Hasil dari penelitian dengan menggunakan debt to asset ratio, debt to equity ratio dan times interest earned menunjukkan bahwa kondisi keuangan PT Bank Central Asia Tbk selama periode 2020-2022 menunjukkan keadaan yang kurang baik. Hal ini dibuktikannya perusahaan tidak mampu melunasi hutang-hutang pada pihak luar dan hasil analisis tidak memenuhi standar umum rata-rata industri. PT Bank Central Asia Tbk hendaknya terus memperhatikan kenaikan jumlah aktiva lancar yang dimiliki sebelum menambah jumlah hutang. Dengan menambah jumlah hutang tanpa memperhitungkan jumlah aktiva lancar yang ada, tidak menutup kemungkinan perusahaan akan mengalami kesulitan dalam memenuhi kewajiban-kewajibannya. Dilihat dari solvabilitas perusahaan, sebaiknya perusahaan mengurangi jumlah hutang jangka panjang sehingga pendanaan operasi perusahaan tidak banyak di biayai oleh hutang.

Abstract

Plastic waste is a type of solid waste that originates from synthetic polymer materials and is difficult to decompose naturally. Plastic waste will become a problem if its presence continues to increase. This will have a negative impact on environmental sustainability. In general, people are only focused on waste management, without thinking about previous problems. This problem is the cause of the lack of waste management. So, it would be better if an analysis was carried out on the problems that occurred. The aim of this article is to solve the source of the problem, so that the right solution can be realized. In the research we conducted, we applied a research method in the form of SLR (Systematic Literature Review) which is a literature review with 5 articles in the last 10 years. The result of this review article is an analysis regarding plastic waste management problems and solutions for Indonesian society. It can be concluded that the right solution can solve problems in the waste management process.

Abstract:  Water is very important for fish biota and fish need to get water quality that is maintained clean without any toxic substances in it. Water pollution due to toxic substances inhibits metabolic processes in fish. The purpose of the research is to determine the effect of water pollution on the operculum movement of tilapia. The research method used was an experiment using 3 fish in each treatment. The results showed that clean water and river water had levels in accordance with Indonesian national standards. Sewer water and tofu waste water do not comply with Indonesian national standards for fish survival. Toxic substances contained in sewer water and tofu waste water cause fish operculum movement very quickly and fish experience death. Tilapia in clean water and river water did not experience death and operculum movement was normal. This research can be used as an illustration that water pollution will damage aquatic biota and cause death.Abstrak: Air sangat berperan penting untuk biota ikan dan ikan perlu mendapatkan kualitas air yang kualitas airnya terjaga bersih tanpa adanya zat toksik di dalamnya.

Abstract

Collaboration and science literacy skills are key indicators in the current learning era. Collaboration trains students to actively engage and make decisions together, while science literacy equips them to think critically and face the challenges of the Industrial Revolution. However, in reality, both skills remain below average among students. This gap highlights the need for an effective learning model to address the problem. Several studies have shown that the Read, Answer, Discuss, Explain, and Create (RADEC) learning model can improve these abilities through a structured and student-centered approach. The objectives of this study are to analyze the effectiveness of the RADEC learning model in improving students' science collaboration and literacy. This research used a quasi-experimental nonequivalent control group design. The sample consisted of class VIII C (experimental) and VIII D (control), selected through purposive sampling. Data were obtained from a collaboration skills questionnaire and students’ pretest and posttest scores to assess improvements in science literacy skills. The results showed that (1) the RADEC model is effective in improving students' science collaboration skills from the t-test with sig (2-tailed)-value is less than 0.05 which means that the structured RADEC model can facilitate the development of affective and cognitive aspects to create a high collaborative learning environment and (2) the RADEC model is effective in improving students' science literacy skills from the t-test with sig (2-tailed)-value is less than 0.05 which means that the RADEC model through its stages is able to build better conceptual understanding to develop students' science literacy significantly. This study concludes that the RADEC learning model is effective in improving the science collaboration skills and science literacy of junior high school students.    Keywords: RADEC, science collaboration skill, science literacy.
