Abstract

Coleus amboinicus is one plant with a good antioxidant content. The concentration of antioxidant from C. amboinicus could be increased by using a treatment fermented plant extract (FPE) containing paitan grass. C. amboinicus is potential to be used as raw material to produce herbal tea such as green tea and black tea because of its high antioxidant content. The objective of this study was to analyze the total phenolics, flavonoids, and antioxidant activity from tea product of C. amboinicus. Antioxidant activity was analyzed using one method, that Ferric Reducing Antioxidant Power (FRAP). The results showed that C. amboinicus treated with FPE paitan grass had the highest total phenolic, flavonoid, and antioxidant activity content than control. The green tea produced using FPE paitan grass had the highest content of total phenolic and flavonoid i.e., 25,596 Gallic Acid Equivalent (GAE) mg/g of dry weight (DW) and 5,632 Catechin Equivalent (CTE) mg/g of DW, respectively. Antioxidant activity analyzed by using FRAP method also showed that the highest antioxidant was found in green tea treated using FPE paitan grass. It can be concluded that green tea C. amboinicus treated by FPE paitan grass is a good source of phenolic, flavonoid, and antioxidant.

Abstract

Endophytic fungi lives within healthy plant tissues without causing damage to the host plant. Endophytic fungi LBKURCC69 was one of the endophytic fungi that was isolated from the tubers of dahlia plant (Dahlia variabilis). Morphological identification showed that endophytic fungi LBKURCC69 was Phialophora fastigiata. This identification can’t provide an accurate result because many species of fungi with the same morphological features, that causing misidentification. More accurate species identification can be done by molecular identification using rDNA ITS region. Electrophoresis results indicated that chromosomal DNA of endophytic fungi LBKURCC69 was successfully isolated and has a molecular weight of 6124 bp. DNA amplification of endophytic fungi LBKURCC69 on rDNA ITS regions was successfully performed using ITS4 and ITS5 primers with 45°C annealing temperature and produces DNA fragments with a molecular weight of 537 bp.

Abstract

ABSTRACTThe diptheria outbreak in Surabaya indicated that immunization program failure. Immunization is primary preventif effort to decrease morbidity of disease. An immunization service is very important to protect vaccine quality through cold chain so that vaccine potency be optimal. The purpose of this study was to analysis of factors which are assosiated with midwive’s practice of DPT vaccine distribution and storage to outreach. This study is applying observational approach using cross sectional method. Populations are all village midwives in public health center East Surabaya. The numbers of sample were 38 midwives taken using simple random sampling. The dependent variable was midwive’s practice of DPT vaccine distribution and storage to outreach and the independent variables of this study were work duration, a history of training of cold chain, sosialization, knowledge, attitude. Primary data were obtained through observation and interview. The results showed that 68.4 % midwive’s practice on DPT vaccine distribution and storage at outreach is good. Independent variable which are significant assosiated with midwive’s practice on DPT vaccine distribution and storage at outreach is sosialization about vaccine distribution and storage (p = 0.026) and value of phi and Cramer’s V = 0.431. Enhancement of socialization again be needed to village midwive as efforts for increase knowledge and attitude.Keywords: midwive, cold chain, vaccine distribution, DPT

Abstract

This research was motivated by the low learning outcomes. The purpose of this study was to determine the effect of the methods of teaching and learning motivation towards learning outcomes through learning activities. The method used in this research was descriptive verification with ex post facto approach and survey. The population in this research was class VIII of odd semester in SMP Negeri 1 Dente Teladas Academic Year 2015-2016 and 69 sample students were determined by Slovin formula. Sample determination method used probability sampling by using simple random sampling. Hypothesis testing was using linear regression path analysis. The results showed that there is an influence of the research results directly or indirectly between students’ perceptions about the teaching methods of teachers and students’ motivation to the learning results of the integrated IPS through the learning activities of students in SMP Negeri 1 Dente Teladas Tulang Bawang. Penelitian ini di latar belakangi oleh rendahnya hasil belajar. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh metode mengajar dan motivasi belajar terhadap hasil belajar melalui aktivitas belajar. Metode yang digunakan dalam penelitian ini adalah deskriptif verifikatif dengan pendekatan ex post facto dan survey. Populasi dalam penelitian ini yaitu siswa kelas VIII Semester ganjil SMP Negeri 1 Dente Teladas Tahun Ajaran 2015/2016 dan sampel 69 siswa yang ditentukan dengan rumus Slovin. Metode penetapan sampel  yaitu probability sampling dengan menggunakan simple random sampling. Pengujian hipotesis menggunakan regresi linier dengan analisis jalur. Hasil penelitian menunjukkan bahwa hasil penelitian ada pengaruh secara langsung maupun tidak langsung antara persepsi siswa tentang metode mengajar guru dan motivasi belajar siswa terhadap hasil belajar IPS Terpadu melalui aktivitas belajar siswa di SMP Negeri 1 Dente Teladas Kabupaten Tulang Bawang. Kata kunci:    aktivitas belajar, hasil belajar, metode mengajar, motivasi belajar.

Abstract

The purpose of this study was to determine whether there is a correlation between hemodialysis frequency and stress level in chronic renal failure patients undergoing hemodialysis at the Hemodialysis Installation of RSUD Dr. M. Yunus Bengkulu City in 2016. The research design used by researchers was a descriptive analytic method, namely research that aims to explain each of the variables studied. The results showed that of 58 respondents with frequency of hemodialysis, there were often 28 respondents (48.3%) with moderate stress levels, 17 respondents (29.3%) with mild stress levels, and there were 13 respondents (22.4 %) with a high stress level while from 9 respondents with hemodialysis frequency there were not often 5 respondents (55.6%) with mild stress levels, 3 respondents (33.3%) with moderate stress levels and 1 respondent (11 , 1) with a mild stress level. Conclusion, There is a significant relationship between HD frequency and stress level in CKD patients at the Hemodialysis installation at RSUD Dr. M. Yunus Bengkulu.   Keywords: Frequency, Hemodialysis, Stress Level
