Sumber daya alam Indonesia begitu banyak salah satunya adalah sumber daya alam berupa batubara. Kalimantan Timur merupakan salah satu provinsi dengan sumber batubara yang melimpah. Masyarakat dan perusahaan menjadikan batubara menjadikan batubara di Kalimantan Timur sebagai sumber pendapatan. Batubara tidak hanya memberikan dampak positif tapi  juga memiliki dampak negatif salah satunya sisa galian batubara yang berupa kolam-kolam raksasa yang menjadi Drainase Tambang Asam  (Acid Mine Drainage). Hal ini menjadi perhatian khusus bagi peneliti untuk mengetahui kesadaran terhadap lingkungan dengan melihat tingkat Literasi Lingkungan masyarakat Kalimantan timur Lingkungan khususnya Mahasiswa pendidikan MIPA FKIP UNMUL. Metode dalam penelitian ini adalah Deskriptif, dengan instrument berupa tes literasi lingkungan yang diadapatasi dan dimodifikasi dari Middle Schools Environmental Literacy Survey/ Instrument (MSELS/ I). Analisis tingkat literasi lingkungan ditransformasikan menggukan pensekoran dari NELA (National Environmental Literacy Assessmen). Dalam pensekoran NELA terdapat empat domain yaitu 1). pengetahuan; 2). Keterampilan kognitif; 3). Sikap; dan 4). Perilaku. Hasil penelitian memperlihatkan bahwa literasi lingkungan mahasiswa FKIP ada pada katagori “Sedang”. Dari katagori tersebut dapat digunakan sebagai dasar untuk meningkatkan literasi lingkungan mahasiswa FKIP Universitas Mulawarman.

Banana is a plant with nutritious fruit and can help prevent stunting. Banana plants are widely cultivated in East Kalimantan, but the type characterization has not been identified. The purpose of this study was to determine the diversity of banana plants in East Kalimantan and to characterize banana plants based on morphology. This research is explorative in nature by identifying directly in the field the cultivated banana cultivars. Morphological characterization of stems, leaves and fruit was carried out based on the banana description contained in IPGRI-INIBAP/CIRAD. The research instrument is a banana morphology observation sheet which contains parameters: leaf habit, pseudostem color, predominant underlying color of the pseudostem, sap color, blotches at the petiole base, blotches color, petiole canal leaf III, color of leaf upper surface, color of midrib dorsal surface, color of leaf lower surface, color of midrib ventral surface, wax on leaves. The result shows that at East Kalimantan is found 12 types of banana cultivars were found, Talas bananas, Rutai bananas, Kepok bananas, Mas bananas, Morosebo bananas, Tanduk bananas, Susu bananas, Maulin bananas, Red bananas, Ambon bananas, Raja bananas, and Cavendish bananas.There are variations in the morphological characteristics of banana plants, leaves and fruit that can characterize each banana.

Questioning skills are very important for prospective teacher students to master in order to help students learn actively in class later. Students' questioning skills are empowered through case study learning of environmental pollution subjects. Because it discusses pollution in the environment, a solution needs to be found. The purpose of this study was to determine the questioning skills of prospective teacher students in environmental pollution course using case study method. This qualitative descriptive research was conducted in the odd semester of the 2020/2021 academic year. The measurement instrument was in the form of scoring the students' questioning skill level based on the cognitive level of the revised bloom taxonomy. The research data were analyzed by using the percentage technique. The results showed that the questions asked by students at the low order thinking skills level were 83.33% and the high order thinking skills level was 26.66%. Furthermore, it is necessary to habituate students with asking questions with more intensive assistance and lecturers can provide more examples of questions at the high order thinking skills level.
