Abstract

Two species of scad fish (Decapterus russelli and D. macrosoma) is a major catch of purse seine in almost fishing area, its contributed approximately 58%. Production data of scad fish is based on catch data of purse seine which having fishing base in Java (2006-2007). Chlorophyll-a concentration, sea surface temperature and Photosyntetic Available Radiation (PAR) was derived from satellite imagery AQUA MODIS. That data is used to estimate primary productivity with Vertically Generalized Production Model (VGPM). The effect of ENSO (El Niño-Southern Oscillation) to scad fish fisheries also discussed. This research is aimed to get information about the effects of ENSO to primary productivity and abundance of scads in the southern part of Makassar Strait. Results showed scad fish abundance in the waters of the southern Makassar Strait fluctuates according to season, the peak abundance lasted for three months between November to January. Utilization of scad fish as 3th tropic level component showed percentage of utilization is 8,93% in 2006 and 14,59% in 2007. AQUA MODIS image data showed the highest chlorophyll concentrations occurred between February to April each year. While the highest sea surface temperature occurs in November-January period. There are indication that ENSO have indirect effect to chlorophyll-a consentrations and sea surface temperature. Both of them having relations with scad fish abundance in Makassar Strait.

Abstract

Latar belakang: Pekerja pembuat knalpot bagian pengelasan perlu mendapat perhatian terhadap potensi gangguan kesehatan. Pekerja las dan Pipefitters (pekerja pada fabrikasi dan mekanik pipa-pipa logam) berpotensi terpapar logam Cadmium (Cd) melalui fume saat proses pengelasan. Cadmium menduduki urutan kedua dalam hal toksisitasnya setelah Hg, kemudian diikuti Ag, Ni, Pb, As, Cr, Sn, Zn. Penelitian ini ingin mengkaji apakah terdapat hubungan antara kandungan kadar cadmium dalam darah terhadap penurunan fungsi ginjal ditinjau dari kadar ureum dan kreatinin pada pekerja las bengkel knalpot.Metode: Penelitian ini menggunakan pendekatan Cross sectional. Penelitian dilakukan dari bulan Mei-Juli 2015. Sampel dihitung menggunakan rumus sampel dan diperoleh sampel 36 orang. Responden yang mengikuti penelitian hingga akhir sebanyak 32 orang.Analisis dilakukan secara univariat dan bivariat.Hasil: Hasil analisis bivariat menggunakan uji korelasi Spearman menunjukkan tidak ada hubungan antara Variabel Luar (umur, kebiasaan merokok, higienitas diri, masa kerja, jumlah jam kerja per minggu, penggunaan masker) dengan variabel bebas (kadar cadmium) dengan nilai Correlation coefficient (r) < 0,349. Kemudian analisis bivariat antara Variabel Bebas (Kadar Cadmium) dengan Variabel Terikat (Kadar Ureum dan Kreatinin) menggunakan uji korelasi Pearson menunjukkan tidak ada hubungan dengan nilai Correlation coefficient (r) < 0,349.Kesimpulan: Tidak terdapat hubungan antara Variabel Luar (umur, kebiasaan merokok, higienitas diri, masa kerja, jumlah jam kerja per minggu, penggunaan masker) dengan variabel bebas (Kadar Cadmium) pada pekerja las bengkel knalpot di Kelurahan Purbalingga Lor. Tidak terdapat hubungan antara Variabel Bebas (Kadar Cadmium) dengan Variabel Terikat (Kadar Ureum dan Kreatinin) pada pekerja las bengkel knalpot di Kelurahan Purbalingga Lor.

Abstract

As screening tool for HIV-1 infection, anti HIV-1 ELISA kit with high sensitivity was proved to be very efficient. Because of its high sensitivity, the use of the kit to screen HIV-1 infection in low risk individuals or in seroprevalence study in population of non-endemic area will reduce its specificity. Therefore, there will be many false positive results which, in turn, will give psychosocial and economical impact to the individuals In question. To evaluate false positive results and specificity of anti HIV-1 kit, 1028 normal individuals with low risk of HIV-1 infection were studied. All positive results from HIV-1 ELISA kit confirmed with confirmative ELISA and Western-blot analysis. The results showed that HIV-1 ELISA kit gave false positive results of 1.17% and specificity of 98,38%. Ninety one point seven percent of false positive results had low-ODs ( 2 ODBP) and poor reproducibility value (8,3%). Seventy five percent of these false positive were from individuals aged 1-15 years and not related to gender as well as socioeconomical status. The probable causes of false positive results are endogenous factors in sera samples such as alteration of density of sera during storage, the presence of anti-granulocyte, anti-HLA, antibody to cultured lymphocyte h9/lllb, and polyclonal hyperglobulinemia. Confirmatory ELISA with antigen control had the same sensitivity and specificity as Western-blot. Therefore, ELISA with antigen control can be used for confirmation test of positive or questionable results obtained from anti HIV-1 ELISA. The kit is cheaper and faster, and is very practical to use, especially in laboratories equipped with ELISA system.Key Word : anti-HIV-1 ELISA - specificity - false positive - confirmatory ELISA - Western-blot.

Abstract

A new problem on hepatitis for Indonesian is hepatitis-C virus (HCV). This infection is endemic, majority sub-clinic and progressive in chronic. Viral transmission is primarily via a parenteral route, while other routes are still in debate.Diagnostic approach should be focused on how this virus developed.KeyWords: hepatitis-C virus molecular biology Westem-blot-HCV blood transfusion epidemiology

Abstract

A new rapid-test, sandwich immunochromatography assay technique has been recently introduced for the routine, rapid, qualitative detection of the presence hepatitis-B surface antigen (HBsAgl. To evaluate the sensitivity of rapid test, we studied 39 sera positive and one sera negative for HBsAg with conventional ELISA method. The study found that the minimal detectable level of HBsAg with rapid test was 4.03 ng/ml (range 3,25-4,03 ng/ml), it was 8 times less sensitive than conventional ELISA method (4,03 vs 0,47 ng/m1)• Many factors such as "eddy diffusion" and structure of HBsAg, humidity, direct contact with sunlight and sera of borderline-low level of HBsAg with conventional ELISA had a potency for lower sensitivity of rapid test; conversely, technical factors such as adhesion, migration and viscosity of the samples do not.Key words : rapid test - dry chemistry hepatitis surface antigen (HBsAg) - sensitivity - ELISA.
