Abstract

Erythrocyte sedimentation rate (ESR) is a non specific test that describes changes in protein plasma and is useful to determine inflammatory case. ESR is determined by using manual and automatic. In big cities, automatic method is more popular now days, but in periphery area, manual method is still the choice. To find out correlation between the results of manual and automatic tests. Cross sectional study was carried out among 200 patients at dr. Wahidin Sudirohusodo Public Hospital of Makassar from September to October 2005. The data were analyzed using R-Square (R2) and regression test using SPSS 11.5. There is significant correlation (P<0.05) among vertical manual, oblique manual and automatic methods. R2 of automatic and vertical methods are 0.95 (the first one hour) and 0.94 (the second one hour), as well as the R2 of oblique and vertical methods are 0.62 (the first one hour) and 0.87 (the second one hour) respectively. There is correlation among the results of the three methods. To convert the result of automatic to vertical, an equation of vertical score = 4.32 + 1.00 (automatic score) can be used. Meanwhile, conversion of oblique score to vertical score is vertical score = 7.58 + 0.99 (oblique score).

Abstract

In Indonesia, coronary heart disease (CHD) as the cause of death is still the highest in number. It is estimated that the numberof deaths is about 535 per 100.000 population. Atherosclerosis represents the main risk factor which could be predicted through thepresence of small dense LDL (sdLDL) in youngsters. To determine the value of sdLDL in youngsters and its correlation with other lipids,a study was conducted cross sectionally in Makassar, from January to August 2006, on 125 youngsters aged 15 to 19 years. Their totalcholesterol, HDL, LDL, TG and ApoB was determined and sdLDL was derived from calculation of LDL/apoB ≤ 1.2. 69 (55.20%) patientsshowed sdLDL value and 56 (44.8%) patients did not show sdLDL value. Statistical calculation showed a significant correlation betweensdLDL and HDL level (p = 0.001), sdLDL and TG level (p = 0.003), and sdLDL and ApoB level (p = 0.036). Percentage of sdLDL valuewas higher in youngsters aged 15 to 19. This proves that the process of atherosclerosis happened early at a young age. Showed by theexistence of sdLDL and therefore sdLDL could be used as a predictor of atherosclerosis which can be prevented if detected earlier.

Abstract

The prevalence of Dengue Hemorrhagic Fever (DHF) in South Sulawesi is still high. Proper and immediate management is importantto reduce the disease morbidity and mortality The aims of this study are to know the between correlate in stages of the disease and valuesof blood IgM-IgG, routine haematology analyses as will as infection status. A cross sectional study was done at Wahidin SudirohusodoHospital Makassar in January – June 2006. The diagnosis of DHF following WHO criteria (1999) and Immunocromatographic unit(ICT) for sera IgM-IGg have been conducted. From 83 collected samples, 37 male (44.6%) and female 46 (55.4%) ranged betweenage 6 months up to 47 year old. The decrease of trombocyte counts (mean 70.120/μL) and increase of (mean 10.09%) were observed.Serological unit result showed 10 (12%) primary infections and 68 (82%) secondary infections. Immunoglobulin G could be detectedin the second day of fever. The samples, 56 (67.5%) were stage I, 15 (18.1%) were stage II, and 12 (14.4%) were stage III or IV, thatmeans there were correlation between infection status and disease’s stages (p<0.01). It can be concluded they routine blood analysisis still useful for diagnosis of DHF, because it was confirmed by rapid serological unit specifically for IgM-IgG in early phase of DHF. Sothey an adequate treatment came out in order to prevent severe case of the disease.

Abstract

CD4 test and Viral Load have been done for initiating, controlling, and deciding the treatment and prognosis of HIV/AIDS.If bothtests cannot be done, clinical symptoms and total lymphocyte count (TLC) can be used. TLC and Hb can be used for monitoring theHIV progressiveness. To evaluate routine blood test results, TLC, and CD4 of HIV/AIDS patients. Cross sectional and descriptive studyfrom October 2005 to April 2006, of 30 patients, i.e. 21 men (70%) and 9 women (30%). Leucopenia was found in 16.67% men and13.33% women. Anemia Hb in 70% men and 30% women with mean value 2.52 g/dl; lymphocytopenia in 46.67% men and 10%women; and netropenia in 16.67% men and 10% women. CD4 was discovered decline in 66.67% men and 30% women with mean value63.4 cell/mm3. TLC in 43.33% men and 16.67% women with mean value 1081.21 cell/mm3. In the study we found i.e. leucopenia,anemia, limfocytopenia, and neutropenia. CD4 and TLC are mostly decline. Further researches in the bigger populations are conductedto consider the parameter of routine blood tests, TLC, and CD4 on HIV/AIDS patients for initiating therapy.

Abstract

Hepatitis is a inflammation process which may present in an acute or chronic phase. A decrease of serum albumin level may befound in liver disease. Ratio de Ritis in mild hepatitis is < 1 while in alcoholic hepatitis is >1. To analyze serum albumin level withratio de Ritis in hepatitis B patients. A cross sectional study was carried out comprising 46 subjects from October 2005 to August 2006measuring albumin level SGOT and SGPT levels using Lyasis autoanalyzer. Thirty eight males and eight females, the level of serumalbumin decreased with an average of albumin level 2.98 gr/dL (p<0.05). Twenty two subjects showed a ratio de Ritis ≤ 1 with theaverage albumin level 3.00 gr/dL and 24 subjects were included in group ratio de Ritis > 1 with average albumin level 2.96 gr/dL(p value = 0.658). There was a decrease of serum albumin level in hepatitis B patient but no significant difference between decrease ofserum albumin level with ratio of de Ritis ≤ 1 and ratio of de Ritis >1.

Abstract

Penelitian ini membahas tentang metode iterasi baru untuk mencari akar-akar persamaan nonlinear dengan variabel tunggal yang merupakan kombinasi metode doubel-Newton dan metode Potra-Ptak menjadi metode iterasi tiga langkah. Selanjutnya, turunan yang muncul pada metode iterasi tersebut ditaksir menggunakan penyetaran dua buah metode berorde empat dan beda maju sehingga diperoleh metode iterasi bebas turunan. Secara analitik ditunjukkan bahwa metode iterasi yang dihasilkan mempunyai orde konvergensi enam dengan empat evaluasi fungsi pada setiap iterasi, sehingga indeks efisiensinya adalah 1,5651. Komputasi numerik untuk beberapa contoh yang digunakan menunjukkan metode iterasi baru lebih efektif jika dibandingkan dengan metode lain yang didiskusikan.

Abstract

Pada proses pemurnian minyak kelapa sawit, pemakaian steam sangat erat hubungannya dengan kehilangan minyak (oil losses). Disatu sisi perusahaan ingin menghemat konsumsi steam untuk meminimalkan biaya produksi, disisi lain oil losses yang besar juga harus dihindari untuk meningkatkan perolehan minyak. Penelitian ini bertujuan untuk menganalisis pengaruh pemakaian dan tekanan steam pada proses pemurnian kelapa sawit dengan menggunakan metode Design of Experiment. Penelitian ini dilakukan dengan empat variasi tekanan (3.5, 3.0, 2.5, 2.0 bar) dan lima variasi pemakaian steam (65, 60, 55, 50, 45 ton) dengan persentase oil losses sebagai respons. Dari hasil penelitian, tekanan steam berpengaruh signifkan terhadap kenaikan oil losses, sementara pengaruh konsumsi steam bisa diabaikan. Oil losses terbesar 20.10% didapatkan untuk tekanan 2.0 bar dan pemakaian steam 45 ton dan oil losses terkecil sebesar 17.80 didapatkan untuk tekanan 3.5 ba.r dan pemakaian steam 65 ton. Kondisi steam yang optimal adalah tekanan 2.5 bar dan pemakaian steam 45 ton.

Abstract

The surface of rupture investigation has been conducted at Nobita Hill, Kampung Jua, Lubuk Begalung, Padang City using the 3-dimensional resistivity geoelectric method in Wenner configuration. The research was conducted in a hilly area with a slope of up to 40º. Data was collected on three tracks with variations in length lengths of 120 and 240 m. The electrode spacing is 6, 12, 18, and 24 m for current and potential electrodes. Data processing was carried out using Res2dinv software to display a 2-dimensional image of the subsurface layer based on the resistivity values measured in the field. The results of 2-dimensional image processing were then modeled in 3 dimensions using Voxler software. Data interpretation of the results obtained by Track 1 has a resistivity value of 1170-2028 Ωm at a depth of 4.5-19.1m. Track 2 has a resistivity value of 1052-1768 Ωm with a depth of 4.5-19.1 m. Track 3 has a resistivity value of 1492-2937 Ωm at a depth of 1.5-19.1 m. The direction of the sliding plane of Tracks 1 and 2 is to the northwest, while track 3 is to the northeast. The results showed that the sliding plane on each track is granite.
