Abstract

This study is motivated by the issues found in observations at school, where the daily teaching activities carried out by teachers show that; teaching and learning activities are classical, the teacher only stands or sits in front of the class, the direct relationship between the teacher and students is rare, and students tend to behave passively, such as coming, listening, reading and writing. To overcome this issues, the researchers conducted a research by applying a three-step type of cooperative learning model interview in learning mathematics in the class. The purpose of this study is to reveal the activities and learning outcomes of students after applying the three-step interview type cooperative learning model. From the results of the study it was found that the learning activities of students during the application of the three step interview cooperative learning model increased at each meeting. Thus it can be concluded that the mathematics learning outcomes of students with learning by applying a three-step interview type cooperative learning model is better than those who do not apply the techniques.

Abstract

ABSTRACT Tobacco is one of the seeds that can be stored for certain period. Seed storage is one of the ways in maintaining the viability of the seeds to meet the needs of the next planting period. Pillen seed technology has developed where in addition to increasing the size of seeds can improve the quality of seeds. Kaolin in pillen has an Al content which is suspected if absorbed by plants will inhibit the growth of tobacco seeds. Giving humic acid is expected to be able to play a role in binding Al, so that the level of Al content in the soil can be lowered so as not to cause toxins to plants. This study aims to determine the effect of pillen seed storage and application of humic acid on the growth of tobacco seedlings. This research used the factorial of complete randomized design (RAL) 2 × 3. The first factor of the concentration of humic acid consisted of without humic acid 0 ml / l and liquid humic acid 6 mL/L. The second factor for the shelf life of the top seeds is 3, 8 and 13 years. Humic acid concentration of 6 ml could support the growth of the tobacco seedlings Keywords : tobacco seeds, seeds saving,humid acid ABSTRAK Tembakau merupakan salah satu benih yang dapat disimpan dalam periode tertentu.

Abstract

Eggplant is a plant that requires appropriate organic fertilization to produce quality fruit. Research on the effect of applying solid organic fertilizer on growth and the level of productivity of local eggplants is the main focus, especially related to growth and yield. The purpose of this study was to determine the growth and productivity of local eggplants against the provision of solid organic fertilizer carried out in paddy fields in Jember. The method used is a completely randomized design (CRD) of two factors, the first factor is the variety factor with 5 levels while the second factor is the factor of solid organic fertilizer consisting of 4 treatment levels so that there are 20 treatment combinations. Each treatment was repeated 3 times, so that there were 60 experimental unit units and each experiment unit consisted of 4 plants. The first factor is pruning with 5 levels including V1: eggplant Phiton, V2: Demak Ijo eggplant, V3: Bonar eggplant, V4: Rondha eggplant and V5: Inayah eggplant. The second factor is the treatment of solid organic fertilizer using 4 levels including P0: without solid organic fertilizer, P1: compost, P2: animal dung (kohe) goat, P3: cow kohe. The results showed that the interaction between eggplants with the trade name Inayah (V5) with the treatment of organic solid fertilizer for cow dung (P3) had optimal number of branches, productive interest and fruit weight. Local varieties of eggplants with the trade name Inayah (V5) have an optimal effect on plant height, number of leaves and productive fruit. The treatment of cow manure (P3) solid organic fertilizer has an optimal effect on plant height and productive fruit. Keywords: Germplasm, Local Eggplant, Organic Fertilizer.
