Abstract

Penelitian ini bertujuan untuk melihat pengaruh ekstrak bunga kenanga (Canangium odoratum) dan bunga kamboja kuning (Plumeria acuminata) terhadap mortalitas nyamuk rumah (Culex quenquiefasciatus). Penelitian ini mengunakan Rancangan Acak Lengkap (RAL) pola faktorial terdiri atas 2 faktor, yaitu faktor A (taraf a1 ekstrak bunga kenanga dan taraf a2 ekstrak bunga kamboja kuning) dan faktor B (taraf b1 konsentrasi 20%, b2 40%, b3 60%, dan b4 80%) dengan 8 kombinasi perlakuan dan 3 ulangan. Data yang diperoleh tersebut dianalisis menggunakan ANAVA. Hasil analisis data tersebut menunjukkan bahwa F hitung ≤ Ftabel sehingga Ha ditolak artinya ekstrak bunga kenanga (Canangium odoratum) dan bunga kamboja kuning (Plumeria acuminata) tidak berpengaruh terhadap mortalitas nyamuk rumah (Culex quenquiefasciatus), karena sifat minyak atsiri yang mudah menguap.

Abstract

Malaria is a common public health problem in the rainy season that can result in transmission to others and even death. Most neighborhoods in the Asian Region underscore immediate effective preventive measures such as control strategies especially in young children and pregnant women. Efforts can be made in vector control of malaria disease by studying the level of knowledge and environmental management around their homes. The objective of the study was to identify the prevalence of malaria and its relation with the level of knowledge in the community. Research design was cross sectional design in South Baturinggit in July - December 2017. The sample was 148 families. The variables measured were malaria prevalence and knowledge level as the main variable. While supporting variables such as gender and age. Data were analyzed using chi square statistic test (χ2) with significant level p<0,05. The results showed that sex factor did not have significant relationship to malaria incidence with p>0,05. The prevalence of malaria was quite high in the South Baturinggit Environment caused by the environmental management factor around the house and the low level of public knowledge.

Abstract

The purpose of this study was to determine the effect of supplementation of turmeric powder (Curcuma longa L.) before mature sex to the level of High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) serum quail of Japan (Coturnix coturnic japonica L.). This study uses an experimental method with completely randomized design pattern. The test animal used is 45 female Japanese quail of female divided into 3 groups, namely; P0: Japanese quail that is not given turmeric powder, P1: Japanese quail given turmeric powder with dose 54 mg/quail/day, P2: Japanese quail given turmeric powder with dose 108 mg/quail/day. Each group consists of 5 repetitions. Levels of HDL and LDL serum were taken at the Japanese quail. The data obtained were analyzed uses analysis of variance (ANOVA) and continued with Duncan test with 95% confidence interval (α = 0.05). The result showed that the powder of turmeric before genital effect (P˂0.05) increased the HDL level and decreased the LDL level of Japanese quail. Provision of turmeric powder at dose of up to 108 mg/quail day were relatively higher raising serum HDL levels and relatively higher lowering LDL levels of Japanese quail.

Abstract

Toxicity study on herb Scurulla atropurpurea has done by using Zebra fish (Danio rerio) embryo. The objective of this research is to study the effect of decocta of parasitic tea leaves on theraphy dosage, MATC, and LC50 to the backbones of Zebra fish embryo. This research is done by laboratory experiment method through in vitro by using research design post randomized control group only. The animal used in this research is Zebra fish embryo less than 3 hours post fertilization after fission process is finished and embryo is entering blastula stage. Total number of sample is 80 embryo and divided into 4 groups: control group without treatment, therapy dosage group (200ug/ml), LC50 group (2066ug/ml) and MATC group (237ug/ml) by decocta of parasitic tea leaves. Sample of Zebra fish embryo is putting in well-plate with 1 embryo per well. Treatment was given untill embryo at 72hpf at temperature 270 C. Data taken during study is analysed using one way ANOVA by SPSS version 16. Treatment with therapy dosage 200, MATC 237 and LC50 of decocta of parasitic tea leaves do not cause curvature of backbone in Zebra fish embrio. It is suspected that active compound in decocta of parasitic tea leaves at all above dosage do not able to disturb the structure and function of backbone.

Abstract

Student center learning leads to changing teacher roles. This resulted in a shift in the role of teachers. Learners are required to have HOTS (High Order Thinking Skill), one of the capabilities including HOTS is critical thinking ability. The purpose of this research is to know the influence of learning model of Reciprocal Teaching (RT) and Problem Based Learning (PBL) to critical thinking ability of high school students on reproduction system material. The method used in this research is quasi experiment with Post-Test Only Control Group Design. After obtained the results of the calculation of ANOVA test one way and critical data, then obtained significance value less than 0.05 is 0.001 <0.05 then rejected H0, meaning there is a difference in the average ability of critical thinking learners. The difference of students' critical thinking ability between the RT experimental class and the Student Team Achievement Divisions (STAD) control class proves that there is an influence of the RT learning model on critical thinking skills. The involvement of learners in PBL learning can help in developing critical thinking skills, because PBL involves the ability of learners to search and investigate logically, critically and analytically so that they can formulate their own problem solving. Based on the results of research and hypothesis testing it can be concluded that there is the influence of learning Reciprocal Teaching (RT) and Problem Based Learning (PBL) on the critical thinking skills of high school students on the material reproduction system.
