This paper aimed to propose e-Learning model as an educational concept to teach introduction to programming for secondary school students. The objective of the model is to determine the components involved by applying collaborative learning in e-Learning, to enhance students' motivation and understanding in the subject Information and Communication Technology/ICT, specifically in topic introduction to programming. The model is developed because the need of fast-paced informatics competencies as it mentioned in Indonesians Secondary School 2006 Curricula. In addition, ICT subject is considered as attractive yet a difficult subject to learn. Therefore, approaches and methods to teach in ICT subject should be designed and delivered carefully. © 2016 IEEE. Source

Tuberculosis (TB) caused by Mycobacterium tuberculosis is a major cause of morbidity and mortality worldwide. Thus far, many candidate genes have been investigated for their possible association with TB. Dendritic cell-specific ICAM-3 grabbing nonintegrin (DC-SIGN) encoded by CD209 is the major receptor of M tuberculosis on human dendritic cells. Previous studies reported inconsistent results on the association between CD209 polymorphisms and TB. We examined whether 9 single nucleotide polymorphisms (SNPs) of CD209 are associated with TB in 2 southeast Asian populations (Indonesian and Vietnamese) by Fisher's exact test. The SNP at -939 in the promoter region exhibited a significant association with TB in Indonesian (GG vs GA + AA, p = 0.0051, odds ratio [OR] = 0.68, 95% confidence interval [CI] = 0.52-0.89) but not in Vietnamese populations. Further extensive studies are required to confirm the contribution of CD209 polymorphisms to TB susceptibility. © 2011 American Society for Histocompatibility and Immunogenetics. Source


The research was conducted to determine the anticarcinogenic properties of "rumput mutiara" (Hedyotis corymbosa (L.) Lam) and "pohpohan" (Pilea trinervia (Roxb.) Wight), by the microculture tetrazolium salt (MTT) assay on the human breast carcinoma dependent-hormone (MCF-7) cell lines. The preliminary results showed that the "rumput mutiara" extract displayed the cytotoxic effects against MCF-7 with IC 50-value of 22,67 μg/ml. However, the "pohpohan" extract did not show the IC 50-value against MCF-7 cell lines. The antioxidative activities of the extracts which could contribute to their cytotoxic properties were also studied. The "rumput mutiara" extract was found to have higher antioxidant activity compared with "pohpohan" extract. The strong cytotoxic properties of the "rumput mutiara" extract could be due to its high antioxidant activity. © 2011 Academic Journals. Source

Tuberculosis (TB) is caused by Mycobacterium tuberculosis and is a major cause of morbidity and mortality worldwide. Many candidate genes have been investigated for a possible association with TB. Toll-like receptors (TLRs) are known to play important roles in human innate immune systems. Polymorphisms in and functions of TLRs have been investigated to identify associations with specific infectious diseases, including TB. Here, we examined whether single-nucleotide polymorphisms (SNPs) in TLRs and genes in TLR signaling were associated with TB susceptibility in Indonesian and Vietnamese populations. A statistically significant association was observed between TB susceptibility in a classified Indonesian female group and rs352139, an SNP located in the intron of TLR9, using the genotype (P = 2.76E-04) and recessive (AA vs AG+GG, P = 2.48E-04, odds ratio = 1.827, 95% confidence interval = 1.321-2.526) models. Meta-analysis of the Indonesian and Vietnamese populations showed that rs352139 was significantly associated with TB in the recessive model. This finding indicated that a TLR9 polymorphism might have an important role in the susceptibility to M. tuberculosis in Asian populations. © 2011 John Wiley & Sons A/S. Source

The roots of Pasak bumi have been used as a traditional medicine as tonic after childbirth in Indonesia. However, the usefulness of its is still empiric. The aim of this research is to evaluate the effect of pasak bumi roots methanol extract and its derived fraction to haematological profile of lactating mice. Each mouse was administered methanol extract and its derived fractions (n-hexane fraction, chloroform fraction, ethyl acetate fraction, and methanol-water fraction) at dose 500 mg/kg rat body weight for 21 consecutive days in lactation period. Positive control group received Moloco+B12 at dose 0.13 gm/kg rat body weight, negative control (placebo) group received 2 mL/kg rat body weight of aquadest daily, and normal control group. There were no significant differences in erythrocytes count, haemoglobin, and haematocrit value among the groups during the study (p>0.05). On the contrary, leukocytes count of methanol extract was higher than normal control, placebo, positive control, and derived fractions of methanol extract (p<0.05), but the differentiation of leukocytes (neutrophils, eosinophils, basophils, lymphocytes, and monocytes) were not significantly different (p>0.05). It can be concluded that the methanol extract haematological profile is more similar to physiological value. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).
