This study aims to determine the effect of the SAVI learning method (Somatic, Auditory, Visualization, Intellectually) on the integrated science learning outocomes of eighth grade students of MTs Riyadlatul 'Ulum. This type of research is quantitative with a quasi-experimental form. The place of research is at MTs Riyadlatul 'Ulum. The population in this study were students of class VIII Mts Riyadlatul 'Ulum. The samples used were class VIII B and class VIII C. Class VIII B became the experimental class and class VIII C became the control class. The prerequisite test in this study used normality test, homogeneity test, and hypothesis testing. Hypothesis test is t-test.             The result of testing the t-test formula is that the t-score value is greater than the t-table (3,249>2,015). This shows that there is an effect of the SAVI Learning Method (Somatic, Auditory, Visualization, Intellectual) on the integrated science learning outcomes of class VIII MTs Riyadlatul 'Ulum. The effect of the SAVI method makes the results significant. The SAVI (Somatic, Auditory, Visualization, Intellectually) method is learning that uses physical movement with intellectual activity and the use of all the senses that have a big influence on learning. Learning using the SAVI method can motivate students to study hard so as to improve student learning outcomes. The SAVI method has the advantage of increasing students' intelligence in a fully integrated manner through physical integration with intellectual activities

This study aimed to determine the effectiveness of the PBL (Prob1em Based Learning) model with animation questions on the cognitive values ​​of class XI students on the Human Movement System at SMAN 1 Jabung. This type of research was quasi-experimental using a non-equivalent control group design technique. The researcher used 2 sample groups, namely Class XI IPA 2 as an experimental class with 29 students using the PBL (Problem Based Learning) model with animation questions and class XI IPA 1 as a control class with 30 students using the PBL (Problem Based Learning) model. ) without animation problems. The instrument in this study used a test in the form of multiple choice questions, namely pretest and posttest. Based on the results of the study using the t-test from the post-test results of the experimental class was 78.84 and the control class 65.2 obtained tscore> t-table (17.48>2.00). Then the effectiveness of the PBL (Problem Based Learning) model with animation questions was known by the gain score in the experimental class of 0.55 (medium). The control class had a gain score of 0.32 (medium). So it can be concluded that the class that uses the PBL (Problem Based Learning) model with animation questions and the class that used the PBL (Problem Based Learning) model without the animation problem were both effective in increasing the cognitive value of the XI science class students at SMA Negeri 1 Jabung

Investigating the potential impact and suitability of tuberculosis active case-finding approaches in the rapidly changing environment of urban Blantyre, Malawi.

Millions of cases of Tuberculosis (TB) go undiagnosed each year. Several approaches are recommended to fill this gap, including community-based active case-finding (ACF). This PhD investigates undiagnosed TB in communities and primary care health clinics in Blantyre, Malawi, and the potential direct and indirect (health promotion) impact of community-based ACF in identifying people with undiagnosed TB. It includes: • A prospective cohort analysis of outpatients at a primary health-care clinic using linked entry and exit interviews. Patients were lost at every stage of the TB diagnosis cascade, with same-day sputum submission only achieved in 4.7% of those clinically indicated to test for TB. • A tuberculosis prevalence survey in Blantyre. A prevalence of 150-189 per 100,000 adult residents was identified, consistent with a several-fold reduction from levels identified in a 2013-14 National TB Programme prevalence survey. Some groups, notably men, remain disproportionately affected. • A systematic review of the impact of ACF beyond directly diagnosed patients for TB, using routine case-notification rate (CNR) ratios as a measure of indirect effect. Twelve studies were identified, with two linked qualitative studies, but these provided insufficient evidence to reach firm conclusions, mainly due to study design issues. • A cluster-randomised trial of door-to-door ACF in Blantyre to assess both direct and indirect impact of ACF on TB case-notifications. No detectable impact was found, with adjusted 91-day CNR ratios 1.12 (95% CI: 0.61-2.07) for bacteriologically-confirmed TB and 0.86 (95%CI: 0.63-1.16) for non-ACF (routinely) diagnosed TB patients. Lack of impact was likely due to several previous years of TB ACF screening activity and rapid declines in TB burden. These results highlight the need for resources to be targeted most effectively to reach those with undiagnosed TB in an environment with rapidly changing TB epidemiology. In Blantyre, approaches likely to bring the highest yield are optimised facility-based screening and ACF targeted to high-risk groups, such as men, or geographic hotspots

PENGARUH INDUKSI GIBERELIN TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN CABAI MERAH (Capsicum annum L) SEBAGAI SUMBER BELAJAR BIOLOGI

The research was conducted on February 2, 2012 until April 30, 2012 at the Green House in University of Muhammadiyah Metro. The purposes of this study are (1) to determine the effect of induction of gibberellin on the growth and production of red pepper plants (Capsicum annum L). (2) To determine the induction of 200 ppm gibberellin can provide growth and production of red pepper (Capsicum annum L) is best. This study used statistical design of experiments using the Rancangan Acak Lengkap (RAL) and the data analysis by using the path on ANAVA toward the production chilies with 3 treatments and 1 control. Each trial has treatments, as follow: without gibberellin induction as a control (H0), 150 ppm gibberellin induction (H1), induction of gibberellin is 200 ppm (H2), and induction of gibberellin is 250 ppm (H3). The population in this study is overall  of the 3 treatments and 1 control with 4 replications, and the total is 16 red pepper plant. The sample in this study is the whole of plants, the total is 12 samples of red pepper plant. Based on the research results can be concluded that;  (1) There is an induction effect of gibberellin on the growth and production of red pepper plants (2) Induction of gibberellin is 200 ppm delivers growth and crop production the best chili. For education research results can be used as a learning resource material of growth and developmental biology.  Kata Kunci:  induksi giberelin, pertumbuhan cabai merah, produksi cabai merah, sumber belajar biologi
