Abstract

This study aims to determine the decrease in glucose levels, MDA levels, and histopathological appearance of the pancreatic organs of Wistar white rats after administration of the ethanol-water fraction of longjack root. This study used a completely randomized design with four treatment groups and six replications. The treatment consisted of normal control, negative control (Na-CMC 0.5% 5 ml/200 g body weight), positive control (glibenclamide 0.09 mg/200 g body weight), and treatment of the ethanol-water fraction of longjack root with a dose of 500 mg/kg body weight. The results showed that the ethanol-water fraction of longjack root at a dose of 500 mg/kg body weight had antidiabetic activity comparable to that of glibenclamide at a dose of 0.09/200 g body weight, namely blood glucose levels and MDA levels in white rats of 123.55 mg/dl and 2.83 nmol/ml. The results of histopathological analysis of the pancreas of white rats showed that administration of the ethanol-water fraction of longjack root could repair damage to the islets of Langerhans due to the administration of streptozotocin-nicotinamide.

Abstract

This study discusses the influence of aerosols on lightning on Java Island using monthly and diurnal observation data from the Tropical Rainfall Measuring Mission (TRMM) for 16 years (1998 - 2013). Aerosol Optical Depth (AOD) was obtained from The Modern Era Retrospective Analysis for Research and Applications version 2 (MERRA-2). Aerosol and lightning data are grouped into rainy (December-January-February) and dry (June-July-August) seasons and diurnal data grouped per 3 hours. The intensity of lightning strikes in the western part of Java Island, such as Jakarta and Banten, is higher than the eastern region, in accordance with the aerosol distribution pattern. The influence of aerosols and lightning in the rainy and dry seasons is relatively stable. However, influence of aerosols on lightning diurnally changes significantly. The strongest correlation between aerosol and lightning was recorded in the afternoon (r = 0.8) and evening (r = 0.9). Although the influence of aerosols on radiation reaches a saturation point during the day, the movement of land and sea breezes plays a dominant role. At night, the influence of aerosols on surface temperature is weakened due to the absence of solar radiation, so aerosols help the electrification of clouds through the formation of ice crystals.

Abstract

The initial investigation in the research conducted was an interview with a Biology teacher and gave a questionnaire to 21 students of class X MIPA SMAN 12 Bungo to find out the needs of students in e-module teaching materials. The use of teaching materials used by students is still in the form of printed books, LKS, handouts, videos and image media that do not contain concepts about Biology material that is easily understood by students. Therefore, e-modules are needed that can help students in the learning process. It is known that students have difficulty understanding the concepts in Animalia and Ecosystem material, resulting in low learning outcomes. Therefore, e-modules are needed that can help students in the learning process. The purpose of this research is to produce e-modules based on discovery learning on Animalia and Ecosystem materials for class X SMA / MA students who are valid, practical and affective. This type of research is development research using the Plomp model. The Plomp model consists of three phases, namely the preliminary research phase, the design and prototyping phase and the assessment phase. The subjects in this study were students of class X SMAN 12 Bungo. The research data consisted of validation sheets, practicality assessment sheets by teachers and students, observation sheets and learning outcomes in the cognitive, affective and psychomotor domains, as well as multiple choice questions to assess the cognitive domain of students. The results showed that the discovery learning-based e-module with an average value of 93.13% with very valid criteria. The results of the practicality assessment by teachers with very practical criteria with an average value of 83.33% and the practicality assessment by students with very practical criteria with an average value of 87.72%. The effectiveness test found an influence on the learning outcomes of the cognitive, affective and psychomotor domains of students. So in this study it can be concluded that the discovery learning-based e-module on Animalia and Ecosystem material that has been developed is very valid, very practical and very effective which can be used in the learning process.
