Air Pollution Simulation From Cirebon Power Plant Activity

Telah dilakukan penelitian simulasi sebaran polutan dari aktivitas PLTU Cirebon dengan menggunakan model gaussian plume. Persamaan gaussian plume digunakan untuk memprediksikan persebaran dan konsentrasi gas polutan di udara. Tujuan dari penelitian ini adalah untuk mengetahui konsentrasi polutan di udara ambien akibat dari aktivitas PLTU dan pemodelan dispersi polutan di udara yang berasal dari dua cerobong asap. Hasil penelitian menunjukkan bahwa konsentrasi maksimum untuk semua parameter masih berada di bawah baku mutu yang telah ditetapkan. Adapun konsentrasi maksimum untuk parameter SOx sebesar 36,89 µg/m3 sedangkan NOx adalah 31,25 µg/m3. Sedangkan simulasi dengan menggunakan dua cerobong asap konsentrasi maksimum SOx sebesar 52,95 µg/m3 dan NOx sebesar 44,86 µg/m3

The Potential of EMSA Eritin to Modulate T Cells (CD4+ and CD8+) in Balb/C Mice Model of Diabetes Mellitus

EMSA Eritin is a medicinal polyherbal contains with soy bean, coconut water and red rice extract. In several studies of this individual components have proven the potential to modulate lymphocyte cells that indirectly lowering blood glucose levels in diabetes meliitus. This study was aimed to analyzing the effect of polyherbal EMSA Eritin on the expression of CD4+, CD8+ and SDF-1 cells population in mice model of diabetes mellitus. Neonatal d-5 mice was intraperitoneally injected with Streptozotocin (STZ) 100 mg.kg-1 BW. Four weeks post injection the mice was treated with EMSA Eritin in three doses 0.3125 mg.g-1 BW, 3.125 mg.g-1 BW and 31.25 mg.g-1 BW for 14 days. Cells Profile of T lymphocyte (CD4+ and CD8+) and chemokine SDF-1 were analyzed by Flow cytometry. Data were analyzed with One-way ANOVA (p<0.05) and Duncan test using SPSS 16.0 for Windows. The result showed that EMSA Eritin significantly increased T lymphocyte (CD4+ and CD8+) in optimum dose 3.125 mg.g-1 BW and suppress SDF-1 production in high dose (31.25 mg.g-1 BW) as well as the blood glucose level measurement. This study suggest that polyherbal EMSA Eritin has a potential to decreased blood glucose level in mice model of diabetes mellitus

Health risk assessment after exposure to aluminium in drinking water between two different villages.

A cross-sectional study was conducted at Mukim Parit Lubok (MPL) and Parit Raja (PR), Batu Pahat, Malaysia. The main objective of this study was to determine the aluminium concentration in drinking water and to perform health risk assessment prediction among respondents from these two residential areas. A total of 100 respondents were selected from the study areas based on inclusive and exclusive criteria. Two duplicates of treated water samples were taken from each respondent’s house using 200mL high-density polyethylene (HDPE) bottles and 0.4 mL (69%) pure concentrated nitric acid were added as a preservative. Aluminium concentrations were analyzed using a Lambda 25 UV/V spectrophotometer. The result showed that aluminium concentration in drinking water from MPL was 0.18 ± 0.022 mg/L and 0.22 ± 0.044 mg/L for PR. Statistical analysis showed that 14 (28%) water samples collected from MPL and 35 (70%) from PR recorded concentration of aluminium above the standard limit set by the Ministry of Health, Malaysia for drinking water guideline (0.2 mg/L). The mean value of Chronic Daily Intake (CDI) of aluminium in drinking water from PR (0.00707 mg/kg/day) was significantly higher compared to MPL (0.00164 mg/kg/day). Hazard Index (HI) calculation showed that all respondents had “HI” of less than 1. In conclusion, there was an unlikely potential for adverse health effects from aluminium intake in drinking water from both study areas. However, it was necessary for some actions to be taken in order to reduce aluminium levels found in drinking water for both locations

Analysis Of Fractional Anisotropy (Fa) Values And Apparent Diffusion Coefficient (Adc) Values In Ischemic Stroke Diseases Of Mri Ge 3 Tesla

Background: Diffusion Weighted Imaging and Diffusion Tensor Imaging is an advanced technique in MRI that shows the diffusion in brain of ischemic stroke disease. Diffusion Weighted Imaging (DWI) shows the lesions without gadolinium contrast agent and produce Apparent Diffusion Coefficient values. Whereas, Diffusion Tensor Imaging (DTI) shows connectivity\u27s of central nervous system that cannot be seen by using conventional MRI. Diffusion Tensor Imaging produces Fractional Anisotropy values. Purpose:This study has aim to analyze the Apparent Diffusion Coefficient values and Fractional Anisotropy values in Stroke Ischemic disease. Methods: Total samples used are 14 samples, consist of 7 (50%) man and 7 (50%) woman with ischemic stroke disease. Each sample deals by Diffusion Weighted Imaging and Diffusion Tensor Imaging sequences. The Region of Interest (ROI) is placed in ischemic stroke lesions and contra lateral side of lesions. Results: The result shows that 9 samples of brain tissue lesions located in the right side and 5 samples in the left side. Right lesions have the average ADC stroke: 0.001748; normal ADC: 0.000954; FA stroke: 0.144522; and normal FA: 0.426111. While, left lesions have the average ADC strokes 0.000979; normal ADC: 0.000835; FA stroke: 0.2556; and normal FA 0.4324. Conclusion: So, the conclusion of this study is Apparent Diffusion Coefficient (ADC) values in case of ischemic stroke can decreases or increases depend on the age of stroke. While, the Fractional Anisotropy (FA) values will decrease without being affected by age of stroke

Scoring Analysis of the Relationship Between Magnetic Resonance Imaging- Anxiety Questionnaire (Mri-aq) with Heart Rate to Patients Anxiety Level at Lumbosacral Mri Examination

Background: Anxiety during MRI examination becomes a common constraint and can have a negative effect that is the quality of the resulting image due to the existence of motion artifacts until the failure of the examination. Purpose: One of the signs of anxiety can be seen an increase in heart rate, in addition there is one questionnaire specifically aimed to determine the level of anxiety in patients with MRI examination, namely Magnetic Resonance Immunization-Anxiety Quistionnaire (MRI-AQ). Method: This research used correlational method with cross-sectional approach. The sampling technique used is purposive sampling. In this research, there were 30 samples. Each sample will be measured heart rate before, during, and after Lumbosacral MRI examination. A Magnetic Resonance Imaging Anxiety Questionnaire (MRI-AQ) was then completed at the time of examination. Collected data were then tested for differences using paired-t test and pearson correlation test. Result: The result of paired-t test shows that there was difference of heart rate during and after examination with p-value 0,036 <α. The patient's heart rate during Lumbosacral MRI was higher than the patient's heart rate after Lumbosacral MRI at 85.63 bpm ± 14.709. Conclusion: Pearson correlation test results showed a correlation between Magnetic Resonance Imaging- Anxiety Questionnaire (MRI-AQ) with heart rate to patient anxiety level at Lumbosacral MRI Examination, this is reinforced by correlation value r = 0.636

Optimalisasi Penggunaan Lahan untuk Memaksimalkan Pendapatan Pemerintah Daerah Kabupaten Sidoarjo (Studi Kasus : Kecamatan Waru)

Nilai pajak bumi dan bangunan di Kecamatan Waru merupakan yang terbesar dibandingkan dengan seluruh kecamatan di Kabupaten Sidoarjo. Namun, persentase kenaikan pajak bumi dan bangunan di Kecamatan Waru dari tahun 2009 sampai tahun 2012 sebesar 7%, jauh lebih kecil dibandingkan dengan kenaikan luasan lahan industri sebesar 27%, luasan lahan permukiman sebesar 23%, dan luasan lahan perdagangan dan jasa sebesar 27,8%. Selain itu, pembangunan yang ada belum memperhatikan aspek keseimbangan lingkungan yang diindikasikan oleh luasan ruang terbuka hijau (RTH) sebesar 3,3%. Oleh karena itu diperlukan upaya untuk memaksimalkan pendapatan melalui pengaturan penggunaan lahan dengan tetap mengalokasikan RTH minimal 20%. Untuk optimalisasi penggunaan lahan tersebut, 2 tahapan penelitian dilakukan sebagai berikut; pertama menentukan faktor pengaruh Perubahan penggunaan lahan industri, permukiman, dan perdagangan dan jasa dengan analisis Guttman; kedua merumuskan model optimalisasi penggunaan lahan dengan menggunakan Linear Programming dengan batasan utama luasan RTH minimal 20% dari luas wilayah. Berdasarkan hasil analisa, diperoleh lima alternatif pengaturan penggunaan lahan dengan alternatif pertama adalah alternatif terbaik sesuai dengan tujuan penelitian. Alternatif ini mengalokasikan luasan lahan industri sebesar 954,83 Ha, permukiman sebesar 1145,92 Ha, perdagangan jasa sebesar 69,66 Ha, dan RTH sebesar 606,4 Ha
