Abstract

This research was conducted at the Balai Pengkajian Teknologi Pertanian (BPTP), South Jakarta. Potential yield of flower cabbage (Brassica oleracea var. Botrytis L.) in Indonesia has decreased, this can be achieved by using a combination of inorganic fertilizers and organic fertilizers to increase the growth and yield of flower cabbage as well as maintain soil health. The purpose of this study was to determine the effect of a combination of vermicompost and NPK fertilizers on the growth and yield of flower cabbage. This study used a single factor randomized block design (RBD) with 12 treatments of combination doses of vermicompost and NPK fertilizers, repeated 3 times. The treatments consisted of a combination of vermicompost fertilizer (160 g, 320 g, 480 g and 640 g) combined with NPK fertilizer (12.8 g, 10.2 g and 7.7 g). The results were analyzed using the F test at the 5% level to determine the best treatment, followed by the Duncan Multiple Range Test (DMRT) at the 5% level. The results showed that the application of vermicompost fertilizer combined with NPK increased plant height, leaf number, and pH, head weight, crop diameter and stover weight. Treatment J with a combination of vermicompost dosage of 640 g and NPK fertilizer 12.8 g obtained the highest yield on the parameters of plant height, number of leaves, weight of head, diameter of crop and weight of cabbage flower stalk. The results achieved from this study were the dosage treatment of vermicompost and NPK fertilizers had a significant effect on the growth and yield of flower cabbage.

Abstract

Reading is one of the most crucial aspects of English language development in school. Strategy or learning method has an important role to improve the students’ ability in reading descriptive text. Think-Pair-Share and Discovery learning were used to facilitate students' reading through descriptive text. The research intended to implement Think-Pair-Share and Discovery learning in reading descriptive text. The research design used a case study. The participants are one teacher and one student at English class of eighth grade. Meanwhile, the instruments used to collect data are observation checklist and interview guide. Thus, the researcher is analyzed by using data reduction, data display, and drawing conclusion and verification. The findings show insight into the positive outcomes of employing the TPS strategy and the discovery learning method when teaching and learning descriptive text. The conclusion based on the observations and interview provided, the researcher has concluded that the Think-Pair-Share strategy and the discovery method are strategies and methods utilized by English teacher to teach reading descriptive texts in the eighth grade classroom. This collaborative approach not only boosts students' self-confidence but also encourages them to be more enthusiastic and willing to solve problems together. Think-Pair-Share strategy through the discovery learning method has been shown to better students' learning outcomes and reading comprehension abilities.
