The research sample consisted of 2 classes with a total of 65 students with a random sampling technique. The experimental class was given learning using a project-based learning model in e-learning, the control class was given learning using a direct learning model. This study shows the following results: (1) there is a positive effect of implementing project-based learning models on e-learning chemical equilibrium material on improving student learning outcomes, obtained tcount = 9.91 > ttable = 1.669 and class N-gain value the experimental class is 0.77 with the high category, while the N-gain for the control class is 0.56 in the medium category. (2) student learning activities in the experimental class are very positive or very good towards, the average percentage is 81.83% with the qualification "very good". (3) students in the experimental class showed a positive or good response in the learning process that took place in the classroom, the average percentage of responses was 76.55% with "good" qualifications.

Differences in Learning Outcomes and Student Activities Taught Using Project Based Learning and Discovery Learning Models on Electrolyte and Non-Electrolyte Solution Materials. This research aims to find out whether there are differences in learning outcomes and learning activities for students who are taught using project based learning and discovery learning. The sample in this research was students of class X IPA 1 as experimental class 1 and X IPA 2 as experimental class 2. This research used quantitative research methods. The data taken in this research are student learning outcomes collected through student posttest scores to measure student learning outcomes and student learning activity observation sheets to measure student activity during the learning process. However, before testing the hypothesis, prerequisite tests are carried out, namely homogeneity and normality tests. The research results showed that there were differences in learning outcomes and student learning activities between experimental class 1 which was taught by implementing PjBL modeling compared to experimental class 2 which was taught by implementing DL modeling. Evidence of this can be given referring to the mean value of learning outcomes for experimental class 1 students which is higher than experimental class 2. Likewise, the learning activities of experimental class 1 students are higher than experimental class 2. From the results of the hypothesis test, using the t test it was found that the significance value smaller than 0.00 < 0.05, so H0 is rejected and Ha is accepted.Keywords : Learning outcomes, student learning activities, Problem Based Learning, Discovery Learning.

Fe deficiency in plants results in yellowing of leaves on plants and also reduces the quality of fruit produced. Fe deficiency in plants can be treated by applying slow release fertilizer which will release the nutrients in the fertilizer slowly according to plant needs so that there will be no problem of deficiency or excess of Fe. Activated Carbon/Alginate/Nanocellulose-Fe Composite can be used as slow release fertilizer because this composite releases Fe slowly with citric acid medium and tested with AAS. The functional groups in the Activated Carbon/Alginate/Nanocellulose-Fe Composite showed no disappearance of the functional groups belonging to activated carbon, alginate or nanocellulose so that it can be said that these three components were successfully made into composites and can be carriers of nutrients in micro-fertilizers.
