Abstract

One of bio-indicator soil fertility is soil mesofauna. Soil mesofauna is soil organism that have an important role in distributing organic matter in the soil, improving soil physical properties, and increasing soil fertility. If there are more mesofauna in an area of land, the ecological conditions of the land have abundant organic material and have good soil conditions. The purpose of this study was to determine the types of mesofauna found in the soil around Arabica coffee plants. The method for capturing soil mesofauna was with a pitfall trap. The results of the identification of soil mesofauna in Arabica coffee plants on Kalibendo plantations were obtained by several species including the Order of Collembola and Subclass of Acarina. Species of the Order of Collembola was found Pseudoparonella sp., Salina celebensis, Isotomurus balteatus, Lobella sp., Hypogastrura purpurescens, and Sminthurides sp. Whereas from the subclass of Acarina was found the family of Ixodidae.

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

BACKGROUND: Traditional medicine that might be useful to treat typhoid fever is earthworms (Pheretima javanica K.). It is important to know whether any substances contained in Pheretima javanica K. extract are toxic and have pharmacological effects, which can be observed from the eosinophil and immunoglobulin E (IgE) levels in the blood.METHODS: Thirty Rattus norvegicus B. were included in this study and were separated into 5 groups, with 6 rats in each group. T1, T2, T3, and T4 were groups of rats treated with 50, 300, 2000, and 5000 mg/kg BW of Pheretima javanica K. ethanol extract granules (PJEEG), respectively, while the control group was a group of rats treated with 0.36 mg Ciprofloxacin. The eosinophil number and the IgE concentration were detected. Physical observations were also conducted to detect any allergic symptoms, toxicity symptoms, or histopathological changes.RESULTS: Administration of PJEEG significantly increased the number of eosinophil in every group, from 49.82 cells/μL to 259.26 cells/μL on average (p<0.001). PJEEG did not significantly affect IgE levels (p=0.624). The results showed that the administration did not cause any allergic and toxicity symptoms. Histopathological analysis of rats’ kidneys and liver also showed that the administration had no significant effect on histopathological changes.CONCLUSION: The administration of PJEEG does not cause allergic symptoms, toxicity symptoms, and histopathological changes in rats. The administrations also significantly increase eosinophil number in rats’ blood. However, the concentration of IgE in rats’ blood was not significantly changed after administration of PJEEG.KEYWORDS: allergies, typhoid fever, earthworms, Pheretima javanica K., eosinophil, immunoglobulin E

Abstract

The learning process that provide an opportunity for learners to learn independently is a reading method such as Think, Talk, Write (TTW), Reading, Questioning, and Answering (RQA). Based on the disadvantages and advantages of TTW and RQA, syntaxs can be combined then it is known as RASI (Reading, Analyzing, Sharing and Inferring). The purpose of this research is to produce RASI learning model with valid criteria based on Borg and Gall development model. The preliminary field testing was conducted at the State Junior High School 4 Jember. RASI learning model is validated by lectures and teachers on March 2016. The data are analyzed by analysis of percentage. The result showed that validation of RASI is 88.61% with very valid criteria. Average of teacher response 81,67% and average of students response is 83,01% with very good critera. RASI learning model is valid and it can be used in main field testing.

Abstract

The reading interest of people living in coastal areas is still low. To improve the reading interest, a module that can support learning and attract students' attention are developed through the use of mnemonic and mind mapping based on the Brain-Based Learning (BBL) approach. The objective of the study is to develop a valid, practical and effective Natural Science module that is suitable for coastal communities. This study is a research and development (R&D) which used the Thiagarajan 4-D Model. The stages were limited into three (define, design, and develop) while the other stage (disseminate) was not conducted. The instruments used for data collection consisted of validation sheets, pre-test post-test questions, and student questionnaire response. The preliminary product testing was conducted in a limited number and in a large group setting. The subjects of the study were students in class 7A, 7C, and 7F of SMPN 5 Situbondo in the academic year of 2017/2018. In terms of validity, practicality and effectiveness, the analysis of the module shows that it was very valid, very practical, and quite effective.

Abstract

Synthetic estrogen hormone that has known by the public is an estrogen that is contained in hormonal contraception or birth control pills. The lack of public knowledge about the action mechanism of oral contraception on the reproductive organs makes people ignoring about the impact of it. This study was conducted to analyze the differences in the induction of estrogen towards the levels of estradiol and histology of the uterus and its utilization as a supplement book of Reproductive System topic in high school. Balb-C female mices were used as the tested animals and Microgynon, the contraceptive pillas trademark was used as a source of estrogen induces. Blood samples were taken at pro-estrus phase, while the uterus was taken at each phase of the estrous cycle. Measurement of estradiol levels was done by ELISA method, whereas the thickness of endometrium is determined on a longitudinal incision of the uterus by the method of preparation of histological paraffin and HE staining. The supplement book was arranged refers to 4-D models. The results showed that there was a difference between the levels of estradiol-induced estrogen treatment with control, but in endometrial thickness among the control treatment with estrogen did not show the differences significantly. The results also showed that the estrogen induction has no significant effect on endometrium thickness at each phases of estrous cycle. The results of research were used as supplement book and it can be used for enriching knowledge of reproductive topic on high school.
