Abstract

Background: Pneumonia is known as a frequent cause of morbidity and mortality among children in developing countries. In children,it caused predominantly by bacteria. Bacteremia has been associated with severity and mortalitas of pneumonia. Identify factors caused bacteremia important to prevent severity and mortalitas of pneumonia. Objective: The objective of this study was to identify risk factors of bacteremia in children with pneumonia. Methods: A retrospective study was conducted in children with pneumonia in Dr. Soetomo Surabaya Hospital from January 2007 to December 2008. Blood cultures be performed on all of this patients. Factors associated with bacteremia were identified following review of medical records include clinical features, laboratory , radiology and blood culture results. Results: Frequency of bacteremia was 8,2% (36 patients) of 438 children with pneumonia. Interval from onset of symptoms to hospital admission more than 5 days (22.69 CI 95%), severe malnourished (OR 9.05 CI 95%), anemia (OR 2.44 CI 95%), leucocyt counts less than 5000/mm3 and more than 20.000/mm3 (OR 2.41 CI 95%) and paO2 less than 80 mmHg (OR 4.25 CI 95%) were at increased risk of bacteremia in children with pneumonia. Conclusion: Risk factors bacteremia in children with pneumonia included age under 1 year, symptoms more than 5 days, severe malnourished ,anemia, leucosyt counts less than 5000/mmand more than 20.000/mm3 and paO2 less than 80 mmHg.

Abstract

Indonesia is one of the countries with the largest number of tuberculosis (TB) cases in the world. Environmental factors play significant roles in infection and disease development in children living with adult active TB cases. The aim of this study was to explore the environmental factors affecting TB risk in children, including humidity and number of people living in the same house with the children.  Using a cross-sectional study design, children living with active TB adults for at least 8 weeks were recruited. The subjects underwent clinical examination, tuberculin skin test (TST) and radiological investigations. Home visits were conducted three times daily, namely in the morning, at midday, and in the evening, to measure humidity by digital hygrometer and to observe home conditions. Of 56 index cases living with active TB adults in an urban low socio-economic setting, 64 contact TB children were recruited. These children were classified as class I with negative TST and no clinical signs, class II with positive TST and no clinical signs, and class III with both positive TST and clinical signs. There were 32 (50%) class I, 10 (15.6%) class II and 22 (34.3%) class III children. However, a sub-sample of 43 showed positive results for Mtb 16S rRNA, indicating that all children were infected. The humidity cut-off point was set at 75%, p=0.04 and EP 2.09 (CI= 1.32-3.29), signifying that children living in houses with a humidity higher than 75%, were twice more likely to be tuberculin positive. Environmental conditions playing a role in disease development were humidity and number of people living in the house.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilakukan dalam rangka membantu meningkatkan efisiensi pertanian jagung petani poktan LMPSDH Wonodadi di lahan Hutan Wonodadi, Lembeyan, Magetan yang selama ini umumnya masih menggunakan cara tradisional sehingga kurang efisien dari segi tenaga, waktu dan biaya. Kegiatan dilakukan dengan merancang mesin terintegrasi antara penggembur tanah dan penanam benih yang mana bagian penanam benih dapat dibongkar apabila akan digunakan secara terpisah. Sistem dirancang dengan mesin 2-tak berbahan bakar bensin campur yang menyerupai sistem traktor-tangan mini dengan bobot sekitar 25 kg sehingga mudah dibawa dan dipindahkan melalui akses jalan hutan yang sempit dan kurang memadai. Perangkat mesin yang dirancang telah diuji cobakan di lahan Hutan Wonodadi dan diketahui bahwa mesin dapat berfungsi dengan layak. Meskipun demikian, berdasarkan hasil evaluasi dan saran dari mitra petani, beberapa perbaikan masih diperlukan terkait penempatan roda pada mesin penggembur tanah dan penggunaan material/sistem pencegah penempelan tanah pada mata lubang mesin penanam benih.

Abstract

The optical energy gap of the semiconducting intrinsic layer plays a crucial role in determining the increase in efficiency. The carbon-based biomass can be a choice for the silicon used as solar cell material. Here, we proposed the best biomass that can be used as a semiconductor component in solar cell applications. Coconut shells as bio-waste and palmyra sap, which are available in most areas of Indonesia, can be the best candidates to be considered. The XRD measurement showed both organic materials have an amorphous phase. The coconut shells sample has two peaks that are identical to graphene peaks, therefore this material is called graphenic-like carbon (GC). Furthermore, from the UV-visible spectroscopy, it was shown that both materials have a high transmittance of more than 95%, which indicates that they have transparent properties. Also, the Tauc plot method gives information about the optical energy gap of coconut shell charcoal (GC) and palmyra sap (a:C) which are 2.67 and 1.83 eV, respectively. From this result, palmyra sap becomes promising material to be applied as an intrinsic layer for semiconducting components in solar cell applications.Keywords: Amorphous phase, Coconut shells charcoal, Optical energy gap, Palmyra sugar.
