The research aims to improve learning outcomes of biological subjects Photosynthesis through the application of learning models of Number Head Together (NHT) students grade VIII H at Junior High School 7 Samarinda in learning 2012/2013. This research is a class action that was implemented in three cycles each cycle consisting of four stages, namely planning, implementation, observation, and reflection. Data obtained through observation and test results to learn in each cycle. First cycle on the average biology student learning outcomes increased by 23,82% from baseline by 43,95 points to 54,42 with an average increase of 23,20 points. In the second cycle, the average value of the study of biology students increased by 3,84% of the value of the learning first cycle by 54,42 points to 56,51 with an average increase of 18,83 points. In third cycle, the results of biological studies of students increased by 1 9,25% of the value of the learning second cycle by 56,51 points to 67,39 with an average increase of 23,26 points. Based on these data it can be concluded that the learning models of Number Head Together (NHT) is able to improve the biological learning outcomes on the subject of Photosynthesis to the VIII H graders in state Junior High School 7 Samarinda in learning 2012/2013. Keywords: Learning Models, NHT, Biological Learning Outcomes.

Almost every subject in this course is generally difficult for students to understand because it is abstract, so we need the right way to overcome it, one of the ways to do learning that demands student activity, which can be done through the guidance of student activity sheets. This research was conducted with the aim of reviewing the implementation of student activity sheets through the use of formulations extract of mantangan (Merremia peltata (L.) Merr.) as organic fertilizer to improve understanding of concept on plant physiology courses. The analysis was carried out descriptively by analyzing the students' understanding of material concepts according to the subject matter specified, namely the subject matter of soil and plant nutrients, as well as plant growth and development. Data collection was obtained through pretest and post-test instruments by looking at the results of students' understanding of concepts which were assessed based on the rubric of understanding concepts. The results showed that the implementation of student activity sheets through the use of formulations extract mantangan as organic fertilizer can improve students' understanding of concepts in plant physiology courses, specifically the subject of soil and plant nutrients, as well as plant growth and development of 26.9%.

Long beans are one of the horticultural plants which are cultivated. However, there was a decrease in production due to pest attacks. This research aimed to determine the effect of giving Saliara stem extract (Lantana amara L) and Takokak fruit extract (Solanum torvum) as a botanical pesticide for fixing pests and diseases on horticultural crops in Kabupaten Kutai Kartanegara. This researchwas conducted for 3 months, starting from May to July 2020, and implemented in Samarinda. Research with Randomized Block Design (RDB), consisted of five treatments including control with five replications, T0 is the control, T1 is a mixture of water and detergent, T2 is the administration of Saliara stem extract (Lantana camara L.) with a concentration of 50%, T3 is the administration of takokak fruit extract (Solanumtorvum) with a concentration of 50% and T4 is the provision of a combination of extract and stem Saliara (Lantana camara) with 50% concentration of takokak (Solanumtorvum) fruit. Then data from observations and calculations are analyzed using Analysis of Variance (ANAVA) and treatment tested with Least Significant Differences (LSD) at the 5% level. This study indicated a mixture of Saliara stem extract and Takokak fruit extract is a very significant effect in reducing pests in long bean plants with the most effective concentration of 50%.

In order to achieve maximum learning objectives, then the teaching support materials needed to guide the teacher in the learning process. The lacks of the teacher’s ability to develop guided inquiry-based learning materials still dominate. This study aimed to determine the teachers' weakness and the obstacles they faced in the process of preparing and developing the learning materials. The research method used were survey and interviews which included a questionnaire containing the teacher's understanding of the learning materials. As for the results of the study related to the teacher’s understanding of learning materials, 80% of teachers did not understand, and 20% of teachers who understood the learning materials used during the practicum. Then the teachers’ obstacles related to developing learning materials, 80% of teachers do not understand how to develop the learning ma...

The research aims to improve learning outcomes of biological subjects Photosynthesis through the application of learning models of Number Head Together (NHT) students grade VIII H at Junior High School 7 Samarinda in learning 2012/2013. This research is a class action that was implemented in three cycles each cycle consisting of four stages, namely planning, implementation, observation, and reflection. Data obtained through observation and test results to learn in each cycle. First cycle on the average biology student learning outcomes increased by 23,82% from baseline by 43,95 points to 54,42 with an average increase of 23,20 points. In the second cycle, the average value of ...
