COMBINATION OF PLANTING METHODS AND MULTIPLE NPK FERTILIZER ON PLANT GROWTH AND PRODUCTION SWEET CORN (Zea mays saccharata Sturt)

This study aims to obtain differences in the response of growth and yield of Sweet Corn (Zea mays saccarhata Sturt) using a single row planting system and a two row planting system. This research was conducted in Sukajadi Village, Banyuasin Regency, South Sumatra Province. Research time in January. This study used a split plot design with 8 treatment combinations which were repeated 4 times. The treatment factors in question are as follows: Main Plot : Single Row Planting System (S1), Two Row Planting System (S2), P0: No treatment , P1: NPK : 60g (plot) P2: NPK : 120g (plot) P3 : NPK : 180g (plot). The variables observed in this study were plant height/plant (cm), length of seed cob/plant (cm), cob weight/plant (gr), production of plots/plot (kg). Based on the results of the study, it was shown that the treatment with a two-row planting system (DB) and application of 300kg/ha compound NPK fertilizer gave the best effect on sweet corn production of 12.96 kg/plot or equivalent to 17.28 tons/ha.

THE EVALUATION OF BIOLOGY TEACHING USING INVERTEBRATE TAXONOMY TEXTBOOK

The purpose of this research is to produce a research book based on invertebrate taxonomy in Biology Lectures using Borg & Gall based development methods combined with Dick & Carey's learning in the Stages of development, namely: preliminary studies, planning, product draft development, product validation tests by experts, lecturers and peer reviewer, product revision, product trial, product revision. Data collection uses a questionnaire with descriptive data analysis techniques. Based on the results of research that has been developed, it is considered very good and feasible to be used as a textbook with an average of 102.5 (81.3%) by the validation team of material experts and learning designs, as well as lecturers and peer reviewers with an average of 72 (82,91 %), The results of trials by students individually, small groups and limited field of textbooks Invertebrate Taxonomy is very good and feasible to be developed with an average value of 730.6 (86.6%).

ANALYSIS OF ABILITY OF BIOLOGICAL EDUCATION ALUMNI IN MANAGEMENT AND IMPLEMENTATION BIOLOGY PRACTICUM

This research is motivated by efforts to improve the quality of graduates of the Biology Education Departement in the management and implementation of practicum in schools. The purpose of this research is to describe the ability of PBL alumni teachers in managing and implementing practicum. The method used is descriptive qualitative and quantitative which provides a careful description of the alumni's ability to manage and carry out practicum. The steps of data collection were questionnaires, observations and documentation studies. The technique used to analyze the data is a descriptive technique with percentages. The results of the study on the ability of the alumni of the Biology Education Study Program in managing practicum showed the following: (1) The planning of the laboratory work program (53.33%) was declared good; (2) Laboratory organization was stated to be very good (33.33%) (3) The implementation of the laboratory work program (46.66%) was stated to be very good; and (4) the supervision and evaluation of the laboratory work program (26.66%) was stated to be very good. While the ability of alumni teachers in carrying out practicum is in the good category (75.3%). Teachers play an important role in the management and implementation of effective practicum
