Abstract

AbstractThis study aims to determine the type of lichen as a bioindicator of air pollution and its potential in biomonitoring NO2 gas emissions in the air using the index of atmospheric purity (IAP) calculation method. The research area was divided into 4 sampling stations. One location is a motorised traffic-free area designated as station 1. Station 2, 3, and station 4 are areas located on roads with different motorised traffic densities. At stations 1, 2, 3 and 4, NO2 pollutant levels were measured following the SNI 19–7119.2–2005 procedure with the Griess Saltzman method. Furthermore, at the same station, the pollution level was also determined by calculating the IAP value. Based on the IAP value, the pollution level at the research area station is in the low-very high category with NO2 gas pollution levels in the range of 7.95–12.1 μg/Nm3/hour. There are 8 species of lichen whose presence can serve as bioindicators of NO2 pollution in the air. These species are Graphis sp., Lecanora sp., Lepraria sp., Dirinaria sp., Graphis scripta, Canoparmelia sp., Ochrolechia sp., and Lecidella elaeochroma. The results of the average measurement of NO2 levels show that NO2 levels at the four sampling stations are still in a safe status because they are still below the air quality standards. The IAP value has a negative correlation with NO2 levels in the air, where the higher the NO2 levels in the air, the lower the IAP value, otherwise if the NO2 levels in the air are lower, the IAP value will be higher. The Pearson Correlation test shows that there is a negative relationship (unidirectional relationship) between NO2 levels in the air and IAP values. The higher the pollutants in an area, the lower the number of colonies and area of lichen cover on trees, especially in lichen species that are sensitive to air pollution.AbstrakPenelitian ini bertujuan untuk mengetahui jenis lichen sebagai bioindikator pencemaran udara dan potensinya dalam biomonitoring emisi gas NO2 di udara dengan metode perhitungan index of atmospheric purity (IAP). Area penelitian dibagi menjadi atas 4 stasiun sampling. Satu lokasi merupakan area bebas lintasan kendaraan bermotor yang ditetapkan sebagai stasiun 1. Stasiun 2, 3, dan stasiun 4 yaitu area yang berada pada ruas jalan dengan kepadatan lalu lintas kendaraan bermotor yang berbeda. Pada stasiun 1, 2, 3 dan 4 diukur kadar pencemar NO2 mengikuti prosedur SNI 19–7119.2–2005 dengan metode Griess Saltzman. Selanjutnya, pada stasiun yang sama ditentukan pula tingkat pencemarannya dengan menghitung nilai IAP. Berdasarkan nilai IAP, tingkat pencemaran pada stasiun area penelitian berada pada kategori rendah-sangat tinggi dengan kadar pencemar gas NO2 berada pada kisaran 7,95–12,1 μg/Nm3/jam. Ada 8 jenis lichen yang kehadirannya dapat berfungsi sebagai bioindikator pencemaran NO2 di udara. Jenis tersebut adalah Graphis sp, Lecanora sp., Lepraria sp., Dirinaria sp., Graphis scripta, Canoparmelia sp., Ochrolechia sp., dan  Lecidella elaeochroma. Hasil pengukuran rata-rata kadar NO2 menunjukkan bahwa kadar NO2 di empat stasiun pengambilan sampel masih dalam status aman karena masih di bawah baku mutu udara. Nilai IAP memiliki korelasi negatif dengan kadar NO2 di udara, dimana semakin tinggi kadar NO2 di udara, maka nilai IAP akan semakin rendah, sebaliknya jika kadar NO2 di udara semakin rendah, maka nilai IAP akan semakin tinggi. Melalui uji Korelasi Pearson, menunjukkan bahwa terdapat hubungan negatif (hubungan tidak searah) antara kadar NO2 di udara dengan nilai IAP. Semakin tinggi polutan di suatu area, semakin rendah jumlah koloni dan luas penutupan lichen pada pohon, terutama pada jenis lichen yang sensitif terhadap polusi udara.

Abstract

Climate change is one of the most critical issues we are currently facing. Considering the devastating impact of climate change to many people in the world, an interdisciplinary approach to climate change mitigation is highly essential. Teachers have a crucial responsibility in transferring knowledge, persuading students, and setting an example for critical thinking and environmental advocacy in order to prepare students for the challenges posed by climate change. The issue of climate change is one of the topics and goals of EFL teachers in preparing students to face climate change. The aim of this research is to explore teachers' knowledge, beliefs, attitudes and preparedness in integrating climate change issues in ELT. This study employed a survey method, which involved 214 Indonesian EFL teachers from various levels of education, from elementary to high school. Data were analyzed through questionnaires, consisting of four parts: teachers’ knowledge, belief, attitude and preparedness in integrating climate change issues in ELT. The results show that there is a correlation between knowledge, belief and attitude towards preparedness in incorporating climate change education in EFL learning. Moreover, most teachers expressed their willingness to teach climate change issues in ELT, despite the score of their knowledge, belief, and attitude regarding climate change. These results shed light on teachers’ understanding of climate change, belief about, and attitude toward climate change issues. Implications of the study include the possibility of incorporating climate change education in EFL learning and EFL sustainable teacher education.

Abstract

Climate change is a global issue that requires awareness and understanding among younger generations to support sustainable environmental actions. This study aims to analyze the profile of climate change literacy among junior high school students (SMP) in Ogan Ilir Regency by considering school accreditation levels A, B, and C. The research employed a quantitative descriptive method using purposive sampling, involving 184 ninth-grade students from three schools. The instrument consisted of 40 items covering three indicators: knowledge, attitude, and competence, with Cronbach’s alpha reliability scores of 0.548, 0.900, and 0.511, respectively. Instrument validity testing showed adequate results, with a KMO value of 0.863, SRMR of 0.072, and GFI of 0.990. The findings indicate that 46% of students were in the moderate category of climate change literacy. The attitude indicator achieved the highest percentage at 48%, reflecting a good level of awareness and concern toward climate change issues. However, school accreditation does not necessarily determine literacy level, as evidenced by SMP C (Accreditation C), which recorded the highest percentage in the high category overall. These results imply the need to strengthen environmentally-based curricula and implement contextual learning approaches to enhance students’ climate change literacy.
