Abstract

AbstrakGembili merupakan salah satu umbi dari kelompok Dioscoreacea. Umbi gembili memiliki kadar inulin yang cukup tinggi sebesar  14,77% yang bermanfaat bagi kesehatan tubuh. Inulin merupakan serat pangan larut (soluble dietary fiber) yang bermanfaat bagi pencernaan dan kesehatan tubuh. Penelitian ini bertujuan menganalisis pengaruh pelarut air dan etanol dengan volume yang berbeda terhadap kadar air dan rendemen inulin umbi gembili. Penelitian ini merupakan penelitian eksperimental dengan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dengan 3 ulangan. Variabel yang diukur dalam penelitian ini yaitu kadar air dan rendemen inulin umbi gembili. Data variabel yang diperoleh dianalisis menggunakan analisis ragam (Uji F) pada taraf keyakinan 95%. Apabila menunjukkan pengaruh nyata makan dilakukan uji lanjut duncan (DMRT) dengan tingkat keyakinan 95% untuk mengetahui ada tidaknya perbedaan pengaruh yang signifikan antar taraf perlakuan. Hasil analisis sidik ragam (DMRT) menunjukkan bahwa terdapat pengaruh pelarut air dan etanol dengan volume yang berbeda terhadap rendemen inulin umbi gembili (P<0,005).  AbstractGembili is one of the bulbs of the Dioscoreacea group. Gembili tubers have a high enough level of inulin of 14.77% which is beneficial for health. Inulin is a soluble dietary fiber that is beneficial for digestion and health. This study aims to analyze the effect of water and ethanol solvents with different volumes on water content and yield of gembili tuber inulin. This research is an experimental research with a completely randomized design (CRD) consisting of 4 treatments with 3 replications. The variables measured in this study were water content and yield of gembili tuber inulin. Variable data obtained were analyzed using analysis of variance (F test) at a 95% confidence level. If it shows the real effect of eating, a duncan further test (DMRT) with a 95% confidence level is needed to determine whether there is a significant difference in effect between the treatment levels. Results of analysis of variance (DMRT) showed that there was an influence of water and ethanol solvents with different volumes on the yield of gembili tubilli (P <0.005).

Abstract

Pre-eclampsia is a cause of death maternal mortality highest in Brebes district (42 %). The cause of pre-eclampsia unknown certainly, Oxidative stress is the one cause of pre-eclampsia. The aimed of this study was to analyze macro and micronutriens intake which are unjustified with the needs as pre-eclampsia risk factors. The research is observational research with design case control. Subjects in the study was mother post partum (20-35 years) which consists of 55 cases (pre-eclampsia) and 55 control (not pre-eclampsia). Nutrient intake was measured by semi quantitative food frequency questionnaires and data MUAC, BMI, Age and education was collected from interviews structured. Data was analyzed by counting odds ratio and method of logistic regression. There was no difference in age and LILA between the cases and control group. The cases had median of long education lower than control. The cases had median of BMI higher than control. Low Magnesium intake (OR = 16,011; 95%CI : 4,886 ? 52,463) and low zinc intake (OR = 10,925; 95%CI : 2,633 ? 45,335) were pre-eclampsia risk factor in high pesticide exposure area.

Abstract

BackgroundPre-eclampsia is the largest direct cause (42%) of maternal mortality death in Brebes district in 2013. The cause of pre-eclampsia is not known with certainty, oxidative stress being one of its causes. The aim of this study was to determine macro- and micronutrient intakes that do not correspond to the needs, as pre-eclampsia risk factors in post-partum women. MethodsThe research was an observational study of case control design. Study subjects were 20-35 year-old post partum women consisting of 55 cases (pre-eclampsia) and 55 controls (non-pre-eclampsia). Nutrient intakes were measured using semi-quantitative food frequency questionnaires and data on levels of pesticide exposure, body mass index (BMI), mid-upper arm circumference (MUAC) and education were collected from structured interviews. Data was analyzed by chi-square tests and multiple logistic regression. ResultsThere was no difference in age and MUAC between the cases and controls. Low vitamin C intake (OR: 20.93; 95% CI: 2.72 – 161.36), high polyunsaturated fatty acid intake (OR: 10.50; 95% CI: 2.47 – 44.57), and low vitamin E intake (OR: 8.57; 95% CI: 2.07 – 35.46) were pre-eclampsia risk factors after controled for pesticide exposure, BMI and education. Low vitamin C intake played the most important role in the incidence of preeclampsia.ConclusionLow vitamin C intake played the most important role toward pre-eclampsia. Greater caution is needed when issuing recommendations regarding the consumption of vitamin supplements in pregnancy, as high doses of some vitamins may be deleterious.

Abstract

One indicator of teaching and learning is that students and students are able to explain again or be able to apply what they get during the teaching and learning process. The use of teaching aids or practices in the teaching and learning process is one way to attract students' attention in the learning process and minimize student saturation in the monotonous learning process and that's it. The purpose of this service is to improve the quality of students' knowledge about Natural Science in the Ikhsaniyah Butterfly MI. This research was in the form of community service carried out at MI Ikhsaniyah Kupu in February 2018. The target or target in this community service was elementary school-aged children who attended school in Ikhsaniyah Kupu. The subject of this community service is students of the Ikhsaniyah Kupu MI class 5 and 6. The method used uses the pre and post method. The results of this study, there is an increase in the quality of students' knowledge about Natural Science in Ikhsaniyah Kupu MI, especially regarding microscopes both benefits, functions and parts of the microscope itself which initially only about 20% of students who understood the microscope after the activity increased to 90% of the total grade 5 and 6 students
