Abstract

This study aims to analyze the effect of implementing an ethnoscience-based Project-Based Learning (PjBL) model on students’ learning activities and learning outcomes. This research employed a quantitative approach with a quasi-experimental design. The research subjects consisted of two classes: an experimental class taught using the ethnoscience-based PjBL model and a control class taught using the conventional PjBL model without ethnoscience integration. The instruments used in this study included an observation sheet to assess students’ learning activities and a multiple-choice test administered before and after the treatment to measure learning outcomes. The results showed that the average score of students’ learning activities was 78.07, with a standard deviation of 9.17 and an achievement percentage of 78.07%, categorized as very active. The improvement in students’ learning outcomes in the experimental class was also higher than in the control class based on the N-gain analysis. The average pretest score was 65.66 (SD = 10.49), which increased to 86.90 (SD = 4.78) in the posttest. The N-gain value of 0.62 was classified as moderate. Inferential analysis using the t-test indicated a significant difference in both learning activities and science learning outcomes between the two classes (Sig. = 0.000). Therefore, the implementation of ethnoscience-based Project-Based Learning has a positive effect on improving students’ learning activities and science learning outcomes.

Abstract

Biodiversity learning in senior high schools is often abstract and weakly connected to students local socio-ecological realities. Local ethnobotanical knowledge can provide a contextual basis for more meaningful biodiversity learning. This study aimed to develop and evaluate Dayak ethnobotany-based biodiversity teaching materials for Grade X students. The study used a Research and Development design with the ADDIE model. The participants were 23 tenth-grade students from one intact class and two biology teachers at SMA Negeri 1 Uut Murung, Central Kalimantan, Indonesia. The student sample represented a limited field trial to examine the feasibility and initial effectiveness of the product in a real classroom context. Data were collected using expert validation sheets, teacher and student response questionnaires, and learning outcome tests with a one-group pretest-posttest design. Product validity using Gregory’s formula obtained a score of 1.00, indicating very high validity. Practicality scores reached 95,5% from teachers and 91,5% from students. Learning outcomes increased from 47.25 to 89.86, with an N-Gain score of 0.83, categorized as high. The greatest improvement occurred in students cognitive understanding of biodiversity, especially its relationship with the local environment and local wisdom-based in conservation. Thus, the teaching materials are valid, practical, and effective for contextual biodiversity learning.

Abstract

This study investigated the effect of Design Thinking-Based Learning (DTBL) on students’ learning independence and creative thinking skills based on adversity quotient (AQ). A quasi-experimental pretest–posttest control group design was employed involving 69 tenth-grade students of SMA Negeri 1 Sidrap. The experimental group was taught using DTBL, while the control group received Project-Based Learning (PjBL). Learning independence was measured using a self-regulated learning questionnaire, creative thinking skills were assessed using a Torrance-based creative thinking test, and AQ was measured using an adaptation of Stoltz’s Adversity Response Profile (ARP). Data were analyzed using descriptive statistics and factorial Analysis of Covariance (ANCOVA). The results showed that DTBL significantly affected learning independence (F = 4.602, p = 0.036) and creative thinking skills (F = 5.052, p = 0.028). The mean posttest score of learning independence in the DTBL class (M = 109.23) was higher than that of the PjBL class (M = 103.00), while the mean creative thinking score in the DTBL class (M = 61.74) also exceeded that of the PjBL class (M = 59.85). AQ significantly influenced learning independence (F = 9.222, p = 0.003), but not creative thinking skills (p = 0.279). A significant interaction between learning model and AQ was found on learning independence (p = 0.020), whereas no interaction effect was observed on creative thinking skills (p = 0.813). Therefore, DTBL was more effective than PjBL in improving students’ learning independence and creative thinking skills.

Abstract

Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk melihat bagaimana gambaran prestasi belajar mahasiswa penerima beasiswa bidik misi tahun akademik 2010/2011 yang kuliah di FMIPA UNM pada satu semester awal. Populasi dan sampel dalam penelitian ini adalah seluruh mahasiswa penerima beasiswa bidik misi tahun akademik 2010/2011. Teknik pengumpulan data adalah teknik dokumenter dengan mengambil data sekunder berupa nilai IPK satu semester awal mahasiswa penerima beasiswa bidik misi yang telah terarsip pada setiap jurusan. Data yang diperoleh dalam penelitian ini dianalisis dengan menggunakan analisis statistik secara deskriptif dan dikategorisasi berdasarkan Pasal 32 ayat 2 Pedoman Akademik Jurusan Biologi FMIPA UNM tahun 2010. Berdasarkan data hasil penelitian yang diperoleh diketahui bahwa prestasi belajar rata-rata mahasiswa penerima beasiswa bidik misi pada satu semester pertama berada pada kategori sangat memuaskan dengan IPK rata-rata 3,01. Apabila dilihat secara perindividu berdasarkan kategorisasi menurut pedoman akademik maka ada 12,28% mahasiswa yang prestasi belajarnya berada pada kategori dengan pujian (cumlaude) (IPK 3,51-4,00), 57,89% mahasiswa yang prestasi belajarnya berada pada kategori sangat memuaskan (IPK 2,76-3,50), dan 26,32% mahasiswa yang prestasi belajarnya berada pada kategori memuaskan (IPK 2,50-2,75). Walaupun demikian masih ada sekitar 1,75% mahasiswa penerima beasiswa bidik misi FMIPA UNM yang prestasi belajarnya berada pada kategori cukup (IPK 2,00-2,49) dan 1,75% mahasiswa yang yang prestasi belajarnya berada pada kategori kurang (IPK 0,00-1,99).

Abstract

Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk menyeleksi (screening) bakteri penambat nitrogen non simbiotik yang diisolasi dari rhizosfer tanaman jagung (Zea mays L.) dan padi (Oryza sativa L.) yang memiliki kemampuanmengekskresikan amonium. Sampel diambil dari daerah Mangkoso, Kabupaten Barru, Provensi Sulawesi Selatan pada daerah rhizosfer tanaman. Isolasi bakteri penambat nitrogen dilakukan dengan menggunakan medium pertumbuhan bebas nitrogen yaitu medium Burk’s dan Ashby. Koloni bakteri yang tumbuh pada medium pertumbuhan selanjutnya dimurnikan dan diuji kemampuan ekskresi amoniumnya dengan menggunakan metode spectrophotometry. Isolat bakteri yang memiliki kemampuan mengekskresikan amonium dikarakterisasi secara morfologi dan fisiologis. Hasil penelitian menunjukkan terdapat 20 isolat bakteri yang mampu tumbuh pada medium bebas nitrogen, namun setelah dilakukan uji ekskresi amonium hanya diperoleh 9 isolat yang memiliki kemampuan mengekskresikan amonium dari masing-masing medium pertumbuhan. Isolat bakteri dan konsentrasi amonium yang diekskresikan masing-masing adalah ABJ211 (179 μg/L), ABP213 (269 μg/L), ABP211 (162 μg/L), ABP131 (254 μg/L), ABP242 (104 μg/L), BBJ221 (263 μg/L), BBJ222 (272 μg/L), BBP222 (269 μg/L) dan BBP214 (257 μg/L). Kesembilan isolat tersebut memiliki karakteristik morfologi dan fisiologis yang bervariasi terutama pada sifat struktur dinding sel (gram), kemampuan hidrolisis pati, gelatin dan kasein, sementara kemampuan dalam mereduksi nitrat dan H2O2 (reaksi katalase positif) serta fermentasi glukosa menunjukkan karakter yang seragam.
