This study aims to analyze the ability of Tree Thinking in students. This type of research is quantitative descriptive, the instrument used in the form of test items on Tree Thinking items on Spermatophyta material. This item is a multiple choice with 5 options. The results of this study are information in the form of item validity, distinguishing features, and level of difficulty of the questions. The results of the analysis show the quality of the items, valid at 95% while those that are not valid at 5%. Based on the ability to distinguish the questions, 10% is considered satisfactory, 50% is categorized as good and 40% is categorized as very good. Difficulties about the data obtained are 85% in the medium category, and 15% are in the difficult category. Data analysis shows that the item has a high validity while the distinguishing power is classified as good and the level of difficulty of the item is classified as moderate.
Abstrak. Analisis kemampuan Tree Thinking pada siswa dilakukan menggunakan metode deskriptif kualitatif. Instrumen yang digunakan berupa hasil tes butir soal Tree Thinking pada materi Spermatophyta. Butir soal ini berupa pilihan ganda dengan 5 opsi. Objek yang diteliti adalah 20 butir soal pilihan ganda yang di ujikan pada kelas XI. Hasil dari penelitian ini adalah informasi berupa validitas butir soal, daya pembeda, dan tingkat kesukaran soal. Hasil analisis menunjukkan kualitas butir soal, yang valid sebesar 95% sedangkan yang tidak valid sebesar 5%. Berdasarkan daya pembeda soal menunjukkan 10% dikategorikan memuaskan, 50% dikategorikan baik dan 40% dikategorikan sangat baik. Kesukaran soal data yang di dapat yaitu 85% berada pada kategori sedang, dan 15% berada pada kategori sukar. Analisis data menunjukkan bahwa butir soal memiliki validitas tinggi sedangkan daya pembeda tergolong baik dan tingkat kesukaran soal tergolong sedang.
