Abstract

This study aimed to determine the effect of the project based learning model with digital microsite media on the critical thinking skills of class VII students at SMP Negeri 1 Samarinda. This study used a quasi-experimental design method with a non-equivalent control group design. The sample consisted of 20 students, with the experimental class using the project based learning model and the control class using the conventional model. The results showed that in the experimental class, the average pre-test and post-test scores increased from 60.35 to 86.95 with an N-Gain of 0.67. While in the control class, the average pre-test and post-test scores increased from 59.7 to 71.65 with an N-Gain of 0.29. The T-test results show that the significance value is 0.000 <0.0005 with t count> t table, so it can be concluded that the project based learning model with digital microsite media has a significant effect on the critical thinking skills of class VII students of SMP Negeri 1 Samarinda on the material of classification of living things.

Abstract

Determine effect of a combination of turmeric rhizome extract (Curcuma longa L.) also temulawak (Curcuma xanthorrhiza R.) on the mortality of Spodoptera litura F.. The experiment used a CRD with five treatment concentrations (0%, 35%, 40%, 45%, and 50%), each replicated five times. Mortality data were analyzed using one-way ANOVA followed by LSD test. Combination of turmeric and temulawak extracts significantly affected armyworm mortality, with the highest mortality rate of 80% observed at a 50% concentration. These findings suggest that plant-based pesticides derived from turmeric and temulawak have potential as an eco-friendly pest control alternative.
