Abstract

Saat ini sekolah belum menerapkan suasana belajar yang mengembangkan kemampuan siswa, terutama dalam kemampuan menyelesaikan masalah dan hasil belajar kognitif siswa. Sehingga tingkatan kemampuan berpikir siswa hanya berada pada tataran berpikir tingkat rendah yang tidak memiliki penalaran dan kemampuan menyelesaikan  masalah yang nyata. Pendekatan pembelajaran berbasis masalah dan strategi pembelajaran kooperatif menjadi alternatif pendekatan pembelajaran yang dapat meningktakan hasil belajar siswa. Penelitian ini bertujuan untuk mengetahui adanya pengaruh penerapan pembelajaran (PBM terintegrasi STAD, PBM dan STAD), kemampuan akademik siswa dan interaksi antara strategi pembelajaran dengan tingkat kemampuan akademik siswa terhadap kemampuan menyelesaikan masalah dan hasil belajar kognitif biologi siswa kelas X SMAN 3 Mataram. Penelitian ini merupakan penelitian quasi experiment  dengan Pretest-Posttes Nonequivalent Control Group Design, perlakuan dengan seting faktorial 2 x 3. Populasi penelitian sebanyak 480 siswa yang tersebar dalam 12 kelas. Teknik sampling dipilih dengan cluster random sampling dan diperoleh 120 siswa yang tersebar dalam 3 kelas. Hasil uji statistik menunjukkan  adanya pengaruh yang signifikan (p<0,05) pada penerapan strategi pembelajaran (PBM terintegrasi STAD, PBM dan STAD) terhadap kemampuan menyelesaikan masalah  dan hasil belajar kognitif siswa.  Tingkat kemampuan akademik siswa (tinggi dan rendah) juga menunjukkan pengaruh yang signifikan (p<0,05) terhadap kemampuan menyelesaikan masalah  dan hasil belajar kognitif siswa. Namun interaksi antara srategi pembelajaran dengan kemampuan akademik siswa tidak berpengaruh terhadap kemampuan menyelesaikan masalah  dan hasil belajar kognitif siswa (p>0,05).

Abstract

This study aims to determine the concentration of growth regulators BAP and   2,4-D which have the highest effect in stimulating the formation of callus melon plants (Cucumis melo) Mai 119 variety. Completely randomized design (CRD) was used in this research. Media used on callus induction was MS medium with addition of several concentration of BAP  (0 mg/L, 1 mg/L, 2 mg/L, 3 mg/L) and 2,4-D (0 mg/L, 1 mg/L, 2 mg/L, 3 mg/L) either alone or in a combination of both. Parameters measured were the time appearing of callus, callus diameter, callus texture, and callus color. Anova followed by Tukey's test was used to the analyse of time appearing of callus. Data of callus diameter was analyzed using Kruskal Wallis test followed by Mann-Whitney test. In the analysis of parameter related to the callus texture and callus color, descriptive test were used. The results showed that there were differences in the effect of growth regulators on the callus formation. The fastest callus induction and the largest diameter of callus were obtained on media with concentration of 2 mg/L BAP and 3 mg/L BAP.Keywords: BAP (benzyl amino purine), 2,4-D (2,4-dichlorophenoxyacetic acid), callus induction, melon (Cucumis melo) varieties Mai 119

Abstract

To improve students' academic ability is necessary to the development of innovation in learning. Development of the learning device will be able to improve the quality of content, process, and learning outcomes of students. In order to achieve these objectives, the steps that need to be done is to analyze the competencies or learning objectives, identifying the characteristics of learners and establish a learning environment. To develop the necessary creativity learning educators to create interesting learning activities. Development of a learning device demands of the curriculum in higher education system. According Kepmendiknas 232 / U / 2000 higher education curriculum is a set of plans and arrangements regarding content and study materials and lessons as well as the delivery and assessment are used as guidelines for the organization of teaching and learning in higher education. This research aims to develop outdoor learning model learning device that is expected to improve the learning outcomes of students. Development of the learning device refers to a model of Dick and Carey. Developed learning tools such as syllabi, lecture events unit, student activity sheet and instruments of learning outcomes in the course of plant morphology. Data were collected using instruments feasibility of device which is validated by validator. The results showed that the learning device such as syllabi, lecture events unit, student activity sheet gets categorized, achievement test gets categorized as very feasible to be implemented on plant morphology courses for students of the second semester.Keywords: Devices, outdoor learning, learning outcomes
