Stunting is a nutritional problem that must be immediately prevented and treated in Indonesia in order to produce a smart and quality generation. The government is working to accelerate the reduction in the stunting rate in Indonesia by issuing Presidential Regulation of the Republic of Indonesia Number 72 of 2021 concerning accelerating the reduction of stunting. The results of the initial survey and discussion with the village midwife of Cot Rabo Baroh found that 5 (five) toddlers were stunted. Stunting that occurred in Cot Rabo Baroh Village was caused by a lack of knowledge of the community, especially parents, about fulfilling nutrition in toddlers.

Education about Moringa leaf nutrition and how to give Moringa leaves to toddlers which aims to provide an understanding to the public about the benefits of giving Moringa leaves to stunting toddlers to fulfill their daily life nutrition. The results of the service showed a significant change in knowledge before and after being given counseling. The majority of pretest results were in the poor category as many as 10 people with a percentage of 33.33%. While the majority of the posttest results were in the good category as many as 15 people with a percentage of 50%. It is hoped that after this community service activity the stunting toddler case will be resolved in Cot Rabo Baroh Village.

This study aimed to determine the effect of the blended learning model on the problem-solving skills of students with high and low self-efficacy as well as their interactions. The research method used was a quasi-experimental research with nonequivalent control group design. The population of this study was all tenth-grade science students of SMA Al-Azhar 3 Bandar Lampung. The sampling technique used was random. The instruments employed in this study were a test in the form of essay questions to measure students’ problem-solving skills, a questionnaire to measure self-efficacy, and observation sheets. The hypothesis had been tested using 2 way ANOVA. The results of the hypothesis testing are as follows: 1) there was an effect of using the blended learning model on problem-solving skills in terms of self-efficacy, 2) there was an effect of self-efficacy on problem-solving abilities, and 3) there was no interaction between the blended learning model and self-efficacy.

Soil fertility is the relationship between the physical, chemical and biological properties needed by plants to grow and develop. The land used as a medium for growing mustard greens is taken from Bahway Village. The soil is treated with organic and inorganic fertilizers to test its fertility. The data analysis used was one way ANOVA and the least significant difference test and a randomized block design with three treatments and two replications. The treatments were: P1=100% organic fertilizer, P2=100% inorganic fertilizer, P3=50% organic fertilizer + 50% inorganic fertilizer and control. Based on the research results, it is known that the type of soil texture in P1 and P2 has a clay-sand texture, while P3 and C have a sandy loam texture. In terms of chemical properties, the pH at P1, P2, P3 and C are 5.53, 5.79, 5.50 and 6.20. For available P values, P1 = 188.31 ppm, P2 = 7.44 ppm, P3 = 113.62 ppm, and C = 2.48. Availability of Cation Exchange Capacity P1 = 22.56me/100g, P2 = 21.80me/100g, P3 = 23.19me/100g, and C = 23.75me/100g. From these results, what showed that the growth of mustard plants increased was the P3 treatment.

The term metacognitive behavior describes the habits of students in solving problems which refers to how well they organize their learning systems. This study tried to apply a learning model that can improve metacognitive abilities classified based on students’ information literacy. The research method used was a 2 x 2 factorial quasi-experiment with a non-equivalent control group design. The simple random sampling technique was used as the sampling technique. The experimental class consisted of 30 students taken from class XI MIA 8 while the control class consisted of 30 students taken from class XI MIA 6. The research instrument was a test in the form of essay questions to measure students’ metacognitive abilities. Information literacy questionnaires and observation sheets were employed to see the implementation of the CORE model. Based on the results of the hypothesis test, it was found that there were differences between high information literacy in the CORE learning model and high information literacy in the PBL learning model, there were differences between the low information literacy in the CORE learning model and the low information literacy in the PBL learning model, there were differences between the high information literacy in the CORE learning model and the low information literacy in the CORE learning model, there were differences between the high information literacy in the PBL learning model and the low information literacy in the PBL learning model, and there was no interaction between the CORE learning model and information literacy on metacognitive abilities.
