Abstract

The oyster mushroom cultivation medium is generally sengon sawdust. As time goes by, there is a buildup of agricultural waste, one of which is cassava skin. Cassava peel contains nutrients that are in accordance with the nutrients needed as a medium for oyster mushroom cultivation. The purpose of this study was to determine the effect of a mixture of sengon sawdust and cassava peels with different weight ratios on the productivity of the brown oyster mushroom (Pleurotus cytidiosus). The research design used was a completely randomized design with 7 treatments, including M0, M1, M2, M3, M4, M5, and M6. Then the data were analyzed with One Way Anova using SPSS 20. The results showed that the M2 treatment (90% sengon sawdust + 10% cassava peel powder) had the highest average wet weight, namely 84.9 g, and the fastest pinhead appearance time, which was 40.2 days after inoculation. Then in the M5 treatment (75% sengon sawdust + 25% cassava peel powder), the highest average number of fruit caps was 22.8 fruit caps. And the One Way Anova test shows that all three parameters have F count > F table. Thus, there is an effect of adding media mixed with sengon sawdust and cassava peels with different weight ratios on the productivity of brown oyster mushrooms.

Abstract

Online learning that lasts more than two years makes it difficult for teachers to measure learning outcomes in the attitude and psychomotor aspects of students. Students tend to be silent and passive which makes learning difficult to be interactive. Teachers need to apply learning innovation strategies so that students are more enthusiastic in learning. This study aims to determine the learning outcomes of class XI MIPA students at SMA Negeri 5 Surakarta in the 2022/2023 school year on the subject of the human reproductive system by applying the Numbered Head Together (NHT) learning model combined with question cards. This study used a quantitative approach with a quasi-experimental method involving two classes, namely class XI MIPA 1 as the experimental class and class XI MIPA 4 as the control class, each of which consisted of 36 students. The instruments used in this study were multiple choice question sheets to determine students' cognitive learning outcomes and observation sheets to determine student activity. The posttest average score for the cognitive aspects of the control class was 78.5 and that of the experimental class was 87.72. Meanwhile, the average percentage of student activity (PKS) for the affective aspect of the control class was 71.14% and that of the experimental class was 82.27%. The data analysis technique uses the Independent Sample T-Test, which was previously tested for normality and homogeneity. The results of the F test show that there is a difference in the average values in the two classes (sig. 0.000 <0.05). The application of NHT is able to increase student activity in class.

Abstract

Red spinach is a vegetable plant of the most common varieties of spinach. This plant has good content for the body such as vitamin A, vitamin C, protein and high polyphenols antioxidants content. Red spinach production in Indonesia is still very low. This can happen because the majority of our people are not very familiar with red spinach and cause its cultivation and marketing to be not very intense. Hydroponics is a farming method without using soil media, but with nutrient solutions or other materials that contain nutrients. The aim of the study was to find out the differences and yields of red spinach plants if the concentration of AB MIX fertilizer was different. The research used the research method used was experimental with an environmental design in the form of a Factorial Randomized Block Design (RBD), with 5 treatments. P0 = husk charcoal, P1 = husk charcoal + 1000 ppm, P2 = husk charcoal + 800 ppm, P3 = husk charcoal + 1200 ppm, P4 = husk charcoal + 600 ppm, and P5 = husk charcoal + 1400 ppm. Analysis using the Honest Significant difference Test (BNJ) with a level of 5% was carried out to determine whether there was an interactions of each treatments. The results showed that the best treatments was P1 with a plant heights of 1.5 cm, a leaf width of 0.7 cm, and a total of 6 leaves.
