Abstract

The objective of this study was to find out the effect of mini research application on contextual learning based for students? attitude at microbiology subject in State University of Medan. A quasi experimental research with pretest-posttest control group design was used in this study. The population of this study was 6th semester students of biology department and 2 classes chosen as the sample by applying cluster random sampling technique. Experimental class was using mini research application on contextual learning based while control class was using direct learning. The instrument used to obtain the data of students? attitude was description questionnaire. The data were analysed by using Mann-Whitney U-Test with used Statistical Package for Social Science (SPSS) 22. The score of attitude were significantly from two classes, that U =78.64, n1 = 35, n2 = 34, p = 0.05, and z = 6.327 1.96 means the null hypothesis was rejected, suggesting that there is an effect of mini research application on contextual learning based for students? attitude. Therefore, it can be stated that mini research application on contextual learning based as a more effective for students? attitude in State University of Medan

Abstract

Propagation of mangosteen is challenging for many reasons, including limited seed set, slow rate of seedling growth, and difficulty with root formations. The objective of this research was to find the best combination of medium and plant growth regulator for in vitro growth and rooting of mangosteeen seed. Various types of explant (a whole seed; seed divided into 2, 3, and 4 cross sections; seed divided into 2, 3, and 4 longitudinal sections) were treated with five concentrations of benzyl amino purine (BAP; 0, 2.5, 5, 7.5, 10 mg/L) for shoot induction in ½ Nitrogen (N) Murashige and Skoog (MS) medium. The shoots were rooted on MS and woody plant medium (WPM) media with several combinations of indole butyric acid (IBA) and naphtalene acetic acid (NAA). Treatments for root induction were applied as follows: (i) low dose, given during induction of rooting, (ii) soaking the base of the shoots in medium treated with a high dose of auxin for 5 days, and then growing the shoots in MS ½ N with 1 mg/L NAA +  1 mg/L BAP medium. Our result show that BAP positively affected mangosteen bud growth. The best medium for mangosteen shoot regeneration was found to be  MS ½ N  + 5 mg/L BAP. This medium induced  the highest number of shoots from the seed explant cut into four cross sections. We found the best medium to induce in vitro rooting of mangosteen shoot was MS ½ N + 3 mg/L indole butiric acid (IBA) + 4 mg/L NAA medium. Some treatment negatively affected growth. Soaking the mangosteen shoot base in a medium with an overly high dose of auxin seemed to disrupt and inhibit growth of the mangosteen shoot.

Abstract

Nanas (Ananas comosus L.) pada mulanya hanya diketahui sebagai tanaman pekarangan, sekarang penanamannya sudah menjadi tanaman perkebunan. Nanas merupakan tanaman yang perlu dikembangkan dalam skala perkebunan karena buahnya bernilai ekonomi, permintaan pasar, komoditi buah ekspor ketiga didunia setelah Negara Filipina dan Thailand. Komoditi nanas telah lama dibudidayakan di Indonesia, memiliki potensi ekspor sangat besar, dapat dikembangkan sebagai buah segar maupun untuk diversifikasi olahan dengan bahan dasar, namun ketersediaan tanaman ini masih kurang. Satu alternatif untuk meningkatkan pertumbuhan nanas yaitu dengan menerapkan tehnik kultur jaringan. Tujuan penelitian ini adalah untuk mengetahui 1) Pengaruh pemberian dosis Zat Pengatur Tumbuh (ZPT) Sitokinin (BAP) terhadap pertumbuhan nanas (Ananas comosus L.) in vitro, 2) Pengaruh pemberian dosis ZPT Auksin (IAA) terhadap pertumbuhan nanas (Ananas comosus L.) in vitro, 3) Pengaruh interaksi ZPT auksin (IAA) dan sitokinin (BAP) terhadap pertumbuhan nanas (Ananas comosus L.) in vitro. Rancangan penelitian ini adalah factorial complete random design (CRD) dengan perlakuan yaitu 1). Dosis ZPT BAP terdiri dari 4 taraf perlakuan yaitu, 0 ppm, 2 ppm, 4 ppm dan 6 ppm dan 2) Dosis ZPT IAA yang terdiri dari 3 taraf perlakuan yaitu 0 ppm, 0,5 ppm, 1 ppm. Parameter pengamatan penelitian ini adalah data pertumbuhan yang diambil pada minggu ke 14 sesudah penanaman, yaitu 1) Jumlah tunas, 2) Jumlah daun, 3) Jumlah akar. Hasil penelitian menunjukkan 1) ZPT Sitokinin, auksin tidak berpengaruh terhadap jumlah tunas, interaksi keduanya mempengaruhi jumlah tunas. 2) ZPT Sitokinin, auksin berpengaruh terhadap jumlah daun, interaksi keduanya tidak mempengaruhi jumlah daun. 3). ZPT Sitokinin berpengaruh terhadap jumlah akar, Auksin dan interaksi keduanya tidak mempengaruhi jumlah akar. Semakin tinggi konsentrasi sitokinin yang diberikan akan semakin menurunkan jumlah akar yang terbentuk.
