Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh organogenesis tanaman jagung (Zea masy L) pada berbagai konsentrasi NAA, Kinetin, Casein Hidrolisa secara In-Vitro. Dilaksanakan diLaboratorium Kultur Jaringan Universitas Cokroaminoto Palopo, dimulai pada bulan Mei sampai September 2015. Percobaan ini disusun berdasarkan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan masing-masing P0 (Kontrol) P1 (1ppm NAA+ 1ppm Kinetin + 1ppm Casein Hidrolisa) P2 (2ppm NAA + 2ppm Kinetin + 2ppm Casein Hidrolisa) P3 (3ppm NAA + 3ppm Kinetin + 3ppm Casein Hidrolisa) masing-masing perlakuan diulang sebanyak 3 ulangan. Data dianalisis secara statistika dengan uji F pada taraf nyata 5 % dan 1 % dan apabilah F hitung perlakuanya lebih besar dari F tabel 5% dan 1 % maka dilanjutkan dengan uji beda nyata jujur (BNJ) pada taraf 5 %. Hasil penelitian ini menunjukkan bahwa zat pengatur tumbuh NAA, Kinetin, Casein Hidrolisa memberikan pengaruh yang tidak nyata teprhadap umur berkecambah, hari muncul akar, tinggi tanaman, lebar daun, panjang daun, jumlah akar, panjang akar, jumlah daun, bobot planlet pada pertumbuhan tanaman jagung dan yang terbaik pertumbuhanya yaitu P3 (3ppm NAA + 3 ppm Kinetin + 3ppm Casein Hidrolisa).

Abstract

Pengaruh Penggunaan Alat Peraga Smart Trash Bin Terhadap Pemahaman Konsep Fisika Materi Teknologi Digital. The purpose of this study is to determine the understanding of the concept of digital technology classes taught and not taught using smart trash bin props, knowing the difference in understanding the concept of digital technology classes taught and not taught using smart trash bin props. The type of research is experimental with a posttest-only control design. The instrument used tests the understanding of concepts. Data analysis techniques use descriptive and inferential analysis. The average score of concept comprehension test results in classes taught using smart trash bin props was 80.42, with a very high category, while in classes that were not taught using smart trash bin props, it was 76.04, with a high category. The average value of the concept understanding test results taught with smart trash bin props is greater than the average value of the concept understanding test results that are not taught using smart trash bin props, so it can be concluded that the use of smart trash bin tools has a positive influence on the understanding of the concept of digital technology material. Meanwhile, the results of hypothetical testing obtained a significant value of 0.194 > 0.05, meaning that there was no significant difference in understanding of concepts between classes taught and not taught using smart trash bin props.

Abstract

The Student Team Achievement Division (STAD) cooperative learning model has been widely applied in various disciplines, including physics learning at the high school level. This study aims to analyze the effectiveness of the STAD model in improving physics learning outcomes through literature studies from various relevant studies. The results of the analysis show that the STAD model is able to increase student involvement in learning, strengthen conceptual understanding, and improve learning outcomes significantly compared to conventional methods. The advantage of STAD lies in the structure of group cooperation that encourages active interaction between students, thus creating a more dynamic and enjoyable learning environment. In addition, this model also contributes to improving students' social skills. However, the implementation of STAD requires careful planning and support from teachers so that learning can run effectively. Thus, the STAD model is recommended as one of the effective approaches in physics learning in high school.
