Abstract:
Answering the challenges in the world of education today is how a teacher is able to provide knowledge to students, in the form of a learning process. Teachers are required to be able to present an interesting learning process so that students have the motivation to follow the learning process from beginning to end. The teacher learning design can combine several methods so that a varied learning process is formed so that the teacher can facilitate all students from various forms of student learning styles. Motivation to learn can also be done by the teacher by giving awards, praise, and mentoring individually or in groups. The motivation of students will produce learning outcomes as desired, because children following the learning process do not feel forced to emerge from within themselves, so that what is given in any form students will be able to process new knowledge for themselves.

Abstract:
This research is an experimental study which aims to see the effect of plant classification practicum activities in improving student’s logical framework and inference skills. The subjects of the study is junior high school students who were randomly selected. The collected data was analyzed using Z and t tests to see the significance of the average student’s score. The criteria for the significance of practicum activities are achieved if the results of the Z and t test calculations differ significantly and the average students score is ≥ 75 students, as well as the number of students who get those score is > 65 students. The results showed that average students’ performance score were 78.2 and 83.1. While question score were 79.5 and 79.2. As well as the results of X and t test calculations show there were a significance in students' grades. Thus the practical activities of plant classification effectively develop the framework of logic and inference skills of students.

Abstract:
Factors that affect quality and taste, one of which is the elevation (height) of coffee plants. This factor is an external factor that is hardlined. The best way is to plant coffee at the most suitable elevation and post-harvest processing. The aim of the study was to see an increase in coffee content and the roasting component of organoleptic coffee. Research uses survey methods and to use Microsoft Excel. This research was conducted at Mount Muria Kudus. The elevation carried out in this study is 400-600 masl, 800-1,000 masl, 1,200 masl and> 1,200 masl. Jenins roasting that is currently under study is mild roast, medium roast and dark roast. The paramaeter observed included the content of antioxidants, ash, air, fat, caffeine and organoleptics which included color, texture, aroma, and taste. The results showed that for Muria Robusta coffee, the higher the elevation the higher the antioxidant content, caffeine and water content, while at the ash and maximum levels at an altitude of 800-1.00 masl and fat content at an altitude of 1,200 masl.

Abstract:
The tongue-in-law plant (Sansevieria trifasciata Prain) contains saponins, flavonoids, steroids and triterpenoids which are natural metabolites that have the potential to control agricultural pests such as armyworms (Spodoptera sp.). Therefore, the aim of this study was to determine the mortality and LC50 value for 72 hours of giving in-law tongue plant extract to Spodoptera litura and the length of the life cycle of S. litura in the laboratory. The research method used a completely randomized design (CRD). The extract of the tongue-in-law plant is obtained from the maceration process of the tongue-in-law plant with ethanol and then concentrated using a rotary evaporator until the thick extract is obtained. The results of the research on the ethanol extract of the tongue-in-law plant on the mortality of S. litura, found that the highest mortality was 63.6% at a concentration of 800 ppm and the lowest mortality value was 36.4% at a concentration of 200 ppm for 72 hours.
