Prevention of vertical transmission of hepatitis B virus infection

Hepatitis B virus (HBV) is the leading cause of chronic viral hepatitis. Annually, almost two million children younger than 5 years acquire the infection, mostly through vertical or horizontal transmission in early life. Vertical transmission of HBV is a high efficacy phenomenon ranging, in the absence of any preventive interventions, from 70% to 90% for hepatitis e antigen positive mothers and from 10% to 40% for hepatitis e antigen-negative mothers. Maternal viraemia is a preeminent risk factor for vertical transmission of HBV. Maternal screening is the first step to prevent vertical transmission of HBV. Hepatitis B passive and active immunoprophylaxis at birth together with antiviral treatment of highly viraemic mothers are the key strategies for global elimination of HBV infection. Strategies are needed to promote implementation of birth-dose vaccination and hepatitis B immunoglobulins in low- and middle-income countries where the prevalence of the infection is at the highest

Antibacterial Activity of Leaf Extracts of Anredera cordifolia (Ten.) Steenis and Muntingia calabura L. Against Streptococcus pneumoniae

Antibacterial resistance in Streptococcus pneumoniae has been increasing and is one of ongoing global concern.  The need to find new antibacterial agents against Streptococcus pneumoniae is of paramount importance. Medicinal plants are prospective sources of antibacterial agents. The aims of the present study were to determine the activity of leaf extraxt of Anredera cordifolia (Ten.) Steenis and Muntingia calabura L. against Streptococcus pneumoniae.  Leaves of Anredera cordifolia (Ten.) Steenis were extracted using 96% ethanol, while the leaves of Muntingia calabura L were extracted using 100% methanol.  The leaf extracts of the two plants obtained were bioassayed for antibacterial activity against Streptococcus pneumoniae ATCC 49619 and a clinical isolate Streptococcus pneumoniae PU 067.  Results showed that leaf extracts of both Anredera cordifolia (Ten.) Steenis and Muntingia calabura L. have antibacterial activity in vitro against Streptococcus pneumoniae ATCC 49619 at crude extract concentrations of 25%, 50%, 75% and 100% (w/v). Both plants extracts showed strongest activity against S. pneumoniae ATCC 49619 at extract concentration of 75%.   In addition, the extracts of both plants have inhibitory activity against growth of the clinical isolate Streptococcus pneumoniae PU 067. Both plant extracts showed strongest activity against S. pneumoniae PU 067 at extract concentration of 100%.  Therefore, leaf extracts of Anredera cordifolia (Ten.) Steenis and Muntingia calabura L. can potentially be used as a source of antibacterial agent for Streptococcus pneumoniae. Keywords: Antibacterial agent, Anredera cordifolia (Ten.) Steenis, Muntingia calabura L., Streptococcus pneumoniae

THE EFFECT OF THE TRI HITA KARANA-ORIENTED PROBLEM-BASED LEARNING MODEL ON ECOLOGICAL ATTITUDES AND LEARNING OUTCOMES

This study aims to determine the effect of the Tri Hita Karana-oriented problem-based learning model on ecological attitudes and science learning outcomes. The population in this study is 135 students, while the research sample is 61 students. The sampling technique uses cluster sampling and random sampling techniques. The data collection method in this study is the questionnaire method and the test method. Ecological attitude data are collected using a questionnaire instrument, while data on students' science learning outcomes are collected using a science learning achievement test. The data analysis technique used in this study is Manova. The results of the study are 1) there is a significant influence of the Tri Hita Karana-oriented problem pased learning model on ecological attitudes; 2) there is a significant influence of the Tri Hita Karana-oriented problem-based learning model on science learning outcomes; and 3) collectively there is a significant influence of the Tri Hita Karana-oriented problem-based learning model on ecological attitudes and science learning outcomes

Pengaruh Variasi Rasio HAF/SRF Terhadap Sifat Vulkanisat NBR

The objectives of the research were to study the effect of HAF/SRF black ratio and the loading of sulfur on vulcanization characteristic, swelling behaviour and compression set of NBR vulcanizates. The ratio of HAF/SRF were 0/70; 10/60; 20/50; 30/40; 35/35; 40/30; 50/20 and 70/0 phr, respectively. The observation of this research consist of curing characteristic, morphology property and swelling equilibrium. Curing characteristic was determined from cure rate index (CRI), vulcanizates morphology was studied by SEM and swelling equilibrium was conducted by immersion test using benzene. The data were analyzed qualitatively to see the respond of the variable on physical properties. The curing characteristic of double filler vulcanizates was higher than those with single filler. Solvent uptake for double filler present in between to those with HAF or SRF. All of vulcanizates indicate the anomalous mass tranfer, with n>0,5 and constant k showed the same trend. The intrinsic diffusivity (D*), sorption and permeation coefficient showed similar trend and the maximum was obtained by the ratio HAF/SRF 0/70

Pengaruh Pemupukan N, P Dank Terhadap Pertumbuhan Dan Hasil Bawang Merah (Allium Ascalonicum. L) Varietas Bima Brebes Danthailand Di Tanah Ultisol

This research aims to determine the effect of N, P and K on the growth and yield of Bima Brebes and Thailand varieties onion and the best dosage to support in ultisol soil. This research has been conducted in the field of Agricultural Extension Center, Geringging Village. Kampar Kiri, Kampar District, Riau Province. This study was conducted in 2x4 factorial experiment arranged in a randomized completely block design (RCBD) comprises two factors. The first factor is varieties consisting of two levels is Bima Brebes and Thailand. The second factor is the dose of fertilizer, N, P, and K comprising 4 levels, namely: urea 250+ TSP 150 + KCl 100 kg/ ha, urea 500 + TSP 300 + KCl 200 kg/ha, urea 750 + TSP 450 + KCl 300 kg/ha dan urea 100 + TSP 600 + KCl 400 kg/ha. Parameters measured were dry weight, weight of tuber per hill, tuber number, tuber wrap, fresh tuber weight per plot and the weight of feaseable storage of tuber per plot. The result showed that the Thailand varieties of urea fertilizer and 1000 kg/ha + TSP 600 kg/ha + KCl 400 kg/ha gives the highest yield of onion crop

Exploring "whistle blower’s" intentions: exploration study on university students

Recently the epidemic corruption case in Indonesia has become increasingly rampant. Efforts to eradicate corruption which has been committed after the reformation era in 1998 do not equal with the corruption proliferation in the decentralization era. In the last five years many corruption cases have been revealed due to the role of whistle blower. This study aimed to explicate the main intentions of whistle blowers who uncover corruption cases. The perception study were conducted on Brawijaya University students so that understanding the intentions of these whistle blowers can be found in the government sector which in fact is a focus of corruption practices. A factor analysis and statistical descriptive analysis were conducted to answer the main question of this study which revealed that there are three main factors in whistle blowing intention and that demographic variables do not affect the perception of whistle blowing intention
