Abstract

The test instrument is a measuring tool in the assessment process used to obtain information in the form of data on student learning outcomes, both cognitive aspects and thinking skills. The use of test instrument to measure students' thinking skills is still rarely used. This study aims to develop an essential thinking test instrument using the Presseisen taxonomy on valid and reliable ecosystem material. This research uses the Research Development (RD) method with the 3D modified development model combined with the test development stages consisting of 6 stages. Data collection in this research was carried with interviews, tests, and test instrument validation sheets. The analysis included content validity analysis, interrater reliability, and Rasch model analysis. The results showed that all items were valid based on content validity. Interrater reliability has a value of 0.783 with a good category. All items are declared fit, but item number 7 contains bias so it needs to be discarded. Cronbach's alpha has a value of 0.68 in the enough category, person reliability has a value of 0.50 in the weak category, and item reliability has a value of 0.99 in the excellent category. The item difficulty level group consists of 2 very difficult questions, 4 difficult questions, 2 easy questions, and 2 very easy questions. Based on the result of the research, it can be concluded that there are 9 items that are declared valid and reliable for use.

Abstract

Instrumen tes yang dapat digunakan untuk mengukur keterampilan berpikir esensial pada pembelajaran biologi masih belum tersedia. Penelitian ini bertujuan untuk mengetahui kualitas instrumen tes berpikir esensial menggunakan taksonomi Presseisen dan tingkat abilitas peserta didik melalui analisis model Rasch. Penelitian ini menggunakan metode deskriptif dengan pendekatan kuantitatif. Sampel yang digunakan berjumlah 363 orang peserta didik. Instrumen yang digunakan adalah instrumen tes berpikir esensial berjumlah 10 butir soal berbentuk uraian. Pengumpulan data dilakukan dengan uji coba instrumen tes. Analisis data dilakukan dengan analisis model Rasch. Hasil penelitian menunjukkan seluruh butir soal fit, namun butir soal nomor 7 mengandung bias sehingga perlu dibuang. Tingkat kesukaran butir terdiri dari 2 soal sangat sulit, 4 soal sulit, 2 soal mudah, dan 2 soal sangat mudah. Nilai Alpha Cronbach sebesar 0.68 berkategori cukup, nilai person reliability sebesar 0.50 berkategori lemah, dan nilai item reliability sebesar 0.99 berkategori istimewa. Person separation sebesar 0.99 dengan nilai H=1,65 dan item separation sebesar 9.55 dengan nilai H=13,06. Person measure diperoleh 178 orang memiliki abilitas tinggi (49%), 18 orang memiliki abilitas sedang (5%), dan 167 orang memiliki abilitas rendah (46%). Person fit diperoleh 254 orang kategori fit (70%), 32 orang kategori tidak fit (9%), dan 77 orang kategori outlier (21%).

Abstract

Indonesia is a country that has high biodiversity. One of Indonesia's biodiversity plants is the croton plant (Codiaeum variegatum (L.) Rumph. ex A. Juss.). The Croton plant is one of the plants used by the general public as an ornamental plant because of the various shapes and colors of its leaves. This research aims to carry out an inventory of various varieties of croton plants in Jeruju Besar Village, Sungai Kakap District, Kubu Raya Regency, West Kalimantan Province. This research is a qualitative descriptive study with stages including taking samples of croton plants followed by identifying and providing descriptions of croton plants. The results of the research show that there are 24 varieties of croton based on the leaves color and shape, namely ‘Daylight’, ‘Mentimun’, ‘Gold Star’, ‘Burgundy’, ‘Bor Merah’, ‘Batik Mini’, ‘Mentega’, ‘Kecapi’, ‘Trisula’, ‘Tiger’, ‘Spaghetti Three-Color’, ‘Kura Lokal Variegata’, ‘Emping’, ‘Koi’, ‘Manik Maya’, ‘Jazzy Hybrid’, ‘Lele Kirmizi’, ‘Holland’, ‘Kura Batu’, ‘Jumbo Jet’, ‘Adreanum’, ‘Keris’, ‘Jet Amerika’, and ‘Kelabang’.
