Abstract

Endophytic bacteria are the most preferred biological agents in the last period to control Pratylenchus coffeae parasitic nematodes in coffee plants Endophytic bacteria are able to control P. coffeae and increase plant growth. The results of the application of endophytic bacteria can be increased through a combination application. This study aims to determine the effect of a combination of endophytic bacterial isolates isolated from a coffee plantation from Kalibendo garden on the growth of Arabica coffee seedlings attacked by P. coffeae nematode. The study used isolates of endocytic bacteria Micrococcus luteus, Micrococcus sp. and Bacillus sp. the density of 109 cfu in two-month Arabica coffee plant seeds with 9 treatments, 4 replications and 3 sub-replication for 4 months of research. The results showed that a combination of endophytic bacterial isolates was able to significantly increase the growth of Arabica coffee plant seeds.

Abstract

Educational problems that exist in the classroom in general, namely the learning process is still dominated by teacher-centered learning and theoretical resulting in low retention and student learning outcomes. One way to improve student retention and learning outcomes requires a revolutionary paradigm by a teacher in the learning process. The BBL (Brain-Based Learning) based SFE (Student Facilitator and Explaining) learning model can improve student achievment and retention. The purpose of this study was to determine the effect of BBL (Brain-Based Learning) SFE (Student Facilitator and Explaining) learning models on student achievment and retention. This type of research was a quasi experimental. Based on the results of the analysis does not significantly influence the student cognitive (p = 0.134), influencing the student psychomotor (p = 0.006), significantly influence the student affective (p = 0,000), and significantly influence the student retention (p = 0,000).

Abstract

HOTs is the main purpose of 21st-century science learning. Individu with HOTs will able to make a connection between facts and concepts, apply it into any new situation to solve the problem. The aim of this research was to developed integrated science test instrument to measure HOTs level of junior high school students. Oriondo and Antonio models’ was adapted and used in this research method. The test was developed in the reasoning-multiple choice form with three category based on PISA and Marzano HOTs competencies. The item analysis involved content validity, empirical validity, reliability, and difficulty index. Rasch model analysis through Quest and Ministep software output showed (1) Mean of INFIT MNSQ level at 1.00±0.12 that shows fit item with Rasch Model or empirical validity of items; (2) Level of INFIT MNSQ for all item between 0.77 and 1.33; (3) Vary of difficulty index; 34 items were at difficulty index level between -2 and +2; (4) junior high school students’ HOTs in SMP IT Multazzam Banyumanik was at low level because they are difficult in giving explanations or arguments about the options that have been selected. Thus, the integrated science test instrument developed can be used to measure students' HOTs.
