Development of an interactive e-module of integrated science with the Connected type on energy topic for Junior High School (SMP) aims to develop an interactive e-module of integrated science that includes biology, physics, and chemistry concepts an interrelate unity in energy topics. That expected to strengthen the student concept knowledge. The Research and Development (R & D) design with the Plomp model was employed. Collection data procedures used validation sheets and user responses questionnaires by the validator team, teachers, and students. Assessments involved material substance, learning design, display (visual communication), and software utilization. Data analysis results showed the validation percentage from the material and media experts are 94.99% and 96.96%, with very valid criteria. Through the teacher's responses, obtain 95.00% (very good practicality criteria). The 92.45% on the one and one test and 92.71% on the small group test, both on very interesting criteria from students. Its means, the interactive e-module has been valid and suitable for use in the learning process.

The purpose of this study was to develop Biology learning media with Mixed Reality applications using Pyramid Holograms. This research is a qualitative descriptive study. The research was conducted in two stages, namely the problem identification stage and the development stage. The problem identification stage is done by questionnaire and student test results and the development stage by designing Mixed Reality media. The results of the study were in the form of motion system material media with Pyramid Hologram technology that can be used in the learning process.

The purpose of this study was to (1) determine whether the probiotic bacteria Lactobacillus fermentum InaCC B1295 were able to adapt (compatible) to mustard greens (Brassica junceae L.). (2) Knowing the effect of the probiotic bacteria Lactobacillus fermentum InaCC B1295 on the growth of mustard greens (3) Obtain the best concentration for the growth of mustard greens. This was an experimental study and used a completely randomized design (CRD) with 4 treatments and 4 replications to obtain 16 experimental units. The data were analysed using SPSS version 9.1.3 and ANOVA, then followed by Duncan's New Multiple Range Test (DNMRT) at 5% level. The results showed that the application of the probiotic Lactobacillus fermentum InaCC B1295 was significantly different from the control. So it can be concluded that the probiotic bacteria Lactobacillus fermentum InaCC B1295 are able to adapt their life (compatible) to mustard plants, and have a positive effect on the growth of mustard greens. The 105 CFU/mL dilution is a good treatment to stimulate the growth of mustard plants.
