Abstract

Students in the agroecosystem area have self-motivation to follow low learning which causes their learning outcomes lower. It can be increased by applying Brain-Based Learning (BBL) approach combined with Send A-Problem (SAP) collaborative learning model. This is a development research using 4-D model. Only 3 stages were chosen; define, design, and develop. The research aims to produce a valid, practical and effective SAP based on BBL to increase students' metacognitive awareness and learning outcomes. The average of product validation is 88 (very valid category). The average percentage of students' metacognitive awareness was 66.31 (developing category) before the application and 85.85 (very good category) after the application of the learning. Normalized gain analysis result is 0.62 referred to medium category, which means that there is an increase in student learning outcomes. The average percentage of student (84.33%) and teacher responses (98%) is included in the very practical category.

Abstract

Abstract: Granules extract of clime fruit (Citrus aurantifolia L.) is a biolarvasida in eradicating Aedes aegypti mosquito larvae L. Granules extract of lime fruit (Citrus aurantifolia L.) can kill mosquito larvae because its content of limonoida, tannin, flavonoid, and volatile oil. The compound is lethal to the larvae which will enter the body of the larvae of the Aedes aegypti L. mosquito which disrupts the systems in its body. The purpose of this article is to determine the safety of lime fruit (Citrus aurantifolia L.) extract granules on non-target animals, namely tadpoles. Tadpole has the same habitat with mosquito larvae so it is done safety test of citrus fruit extract granule (Citrus aurantifolia L.). Tadpole is a larval phase in Amphibi that continues to experience morphological development in water. The initial phase of tadpoles growth is a phase of adaptation to its habitat. Individuals who can not adapt well will experience a faster death. The research method used is laboratory experimental. The analysis used is ANOVA. The independent variables in this study were the variety of granules extract concentration of citrus fruit (Citrus aurantifolia L.). Tadpole mortality became the dependent variable in this study. Tadpole mortality is characterized by tadpoles collapsing at the time of administration of granules. The results showed that the lime extract granules (Citrus aurantifolia L.) proved safe. Keywords: Granules, Mortality, Tadpole

Abstract: Avocado leaves (Persea americana Mill.) historically used as a herbal medicine used to ease the expense of urine and crushed a kidney stone in the urinary tract. Avocado leaves contain sugar, d-parseit, quercetin, flavonoids, and compounds sterin. The availability of avocado leaves in the society becames a great opportunity to be utilized as a herbal medicine, it is unknown yet whether the avocado leaves extract was able to decrease edema glomerulus and cell damage in the kidneys. The aim of this research knew the effect of ethanol extract of avocado leaves to decrease edema glomerulus and cell damage kidney of white rat. The research method used The Post Test Only Control Group Design. The dose was 100 mg/0.2kg bw, 200 mg/0.2kg bw, 300 mg/0.2kg bw, with inducer (ethylene glycol + ammonium chloride) as positive control, the treatment carried out during 10 days. Data analysis used Anova. The results showed for parameter damage the glomerulus with (F = 4.931, p = 0.027, < 0.05) which means there was the effect of the ethanol extracts of avocado leaves significantly to decrease edema glomerulus, while parameters proximal tubule damage with (F = 5.755, p = 0.018, < 0.05) which means there was the effect of the ethanol extracts of avocado leaves significantly to decrease cell damage kidney white rat. The dose of ethanol extract of avocado leaves which are most effective against the decrease of edema glomerulus was 100 mg/0.2kg bw and cell damage kidney white rat was 200 mg/0.2kg bw.

Abstract

Morinda citrifolia L. is known commercially as mengkudu, grows widely throughout in Indonesia and is one of the most significant sources of traditional medicines. In fact, mengkudu contains a very important alkaloids, xeronine. This alkaloid helps in the normalization of abnormally functioning cells. This research aims is to knowing the influence of Morinda citrifolia L. fruit to the number of neutrophil cell in male mice scratch wound. There was 6 group as a treatment group, in which every group contain 4 mice. Every group had different time in neutrophil cell observation, it was 12, 24, 36, 48, 60 and 72 hour/ observation. The result showed that the number of neutrophil cell tend to decrease. And based on LSD test the number of neutrophil cell different signicantly in 48 hour of observation.

Abstract

: Infectious diseases caused by animal vectors are currently still a health problem in the world even in Indonesia, especially the Aedes aegypti mosquito which is the vector for the spread of dengue fever. Chemical control is still a priority for the community, such as the use of abate. Continuous use of abate can cause resistance to the Aedes aegypti mosquito to the next generation and pollute water conditions. One of the control solutions can be done with natural insecticides such as amethyst fruit (Datura metel L.). The purpose of making purified extracts is to remove unnecessary impurities and get a larger content of active compounds and increase the concentration of active compounds. The concentration of amethyst extract (Datura metel L.) used was a concentration of 100 ppm, 500 ppm, 1000 ppm, 1500 ppm, 1gr abate as a positive control and aquades as a negative control. The amount of Lethal Concentration-50 (LC50) purified extract of amethyst fruit (Datura metel L.) with n-hexane was 494.987 ppm. The active compound content of amethyst fruit (Datura metel L.) in the n-hexane fraction after a phytochemical screening test was carried out was positive for alkaloids, steroids, terpenoids and tannins. The toxicity of the purified extract with n-hexane of amethyst (Datura metel L.) against Aedes aegypti mosquito larvae within 24 hours is considered toxic because it has an LC50 value of less than 1000 ppm.

Abstract

Educational problems that exist in the classroom in general, namely the learning process is still dominated by teacher-centered learning and theoretical resulting in low retention and student learning outcomes. One way to improve student retention and learning outcomes requires a revolutionary paradigm by a teacher in the learning process. The BBL (Brain-Based Learning) based SFE (Student Facilitator and Explaining) learning model can improve student achievment and retention. The purpose of this study was to determine the effect of BBL (Brain-Based Learning) SFE (Student Facilitator and Explaining) learning models on student achievment and retention. This type of research was a quasi experimental. Based on the results of the analysis does not significantly influence the student cognitive (p = 0.134), influencing the student psychomotor (p = 0.006), significantly influence the student affective (p = 0,000), and significantly influence the student retention (p = 0,000).

Abstract

One of the efforts to replace chemical insecticides to eradicate DBD is to obtain natural larvicides and it’s so environmentally friendly. Vegetable insecticides are carried out using a purified extraction process. The purpose of this study was to compare the toxicity of the supernatant and precipitated purified extract of mindi leaf (Melia Azedarach L.) on the mortality of Aedes aegypti L mosquito larvae. The samples used in this study ranged from 600-700 Aedes aegypti L mosquito larvae. This study used a design design. Completely Randomized (CRD) and the Minitab 14 for Windows application help to perform the analysis. The results showed the comparison of the toxicity of the purified extract supernatant of mindi leaf (Melia azedarach L). lower with an LC50 value > 1000 while the toxicity of the precipitated purified extract of mindi leaves (Melia azedarach L). higher with LC50 value < 1000. This research can be further tested regarding the magnitude of the toxicity in this study related to the measurement of environmental factors and also related to the KLT test to determine the possibility of new compounds, which are synergistic in the precipitate (fraksi etanol) and supernatant (fraksi n-heksan) in purified mindi leaf extract (Melia azedarach L).
