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 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.

Abstract

Perikanan cumi-cumi telah berkembang di Laut Jawa dan Laut Cina Selatan, didukung oleh alat tangkap bouke ami dan cast net dengan armada penangkap skala menengah. Perikanan berkembang sebagai bentuk diversikasi usaha penangkapan beralih target species akibat terjadinya pergeseran trophic level yang berkaitan dengan perubahan ekosistem serta indikasi pergantian populasi dari sumberdaya ?multi-species?. Kajian distribusi, kelimpahan dan hasil tangkapan Cumi-cumi (Loliginidae) di perairan Paparan Sunda bagian selatan didasarkan pada data monitoring oleh enumerator tahun 2018 terhadap alat penangkap cumi-cumi (bouke ami dan cast net), didukung oleh data pendaratan per kapal di TPI Muara Angke (Jakarta) periode 2012-2018 dan TPI Kejawanan (Cirebon) periode 2008-2018. Observasi lapangan ditujukan untuk mendeskripsikan karakteristik armada, alat tangkap dan aspek operasional penangkapan. Hasil menunjukkan daerah penangkapan cumi-cumi di Paparan Sunda bagian selatan tersebar luas di Laut Jawa dan Laut Cina Selatan, tapi lebih terkonsentrasi di perairan selatan Selat Karimata yang ditunjukkan oleh tingginya intensitas penangkapan (54% dari total trip penangkapan). Namun demikian, secara umum kelimpahan cumi-cumi (ditunjukkan oleh indek kelimpahan CPUE dalam Kg/hari) hampir seragam sekitar 113-133 kg/hari, sedang indek kelimpahan (CPUE) dalam Kg/trip terlihat berbeda. Perbedaan nyata juga terlihat dari total hasil tangkapan cumi-cumi dari Selat Karimata yang mencapai 55% dari total pendaratan cumi-cumi dari paparan tersebut. Secara umum sebagai target species cumi-cumi berkontribusi sebanyak 93% dari total hasil tangkapan pada alat penangkap cumi. Trend kenaikan hasil tangkapan cumi-cumi berlangsung hingga saat ini baik di Muara Angke maupun Kejawanan. Dalam komposisi jenis prosentase cumi-cumi juga menunjukkan semakin tinggi pada hasil tangkapan pukat (cantrang). Hal-hal terkait pengelolaan perikanan cumi sebagai diversifikasi usaha penangkapan dan pengalihan target species juga dibahas.Squids fishery had well developed in the Java Sea and the South China Sea, was supported by the bouke ami and cast net that were using the medium scale boats. The fisheries developed as the fishing diversification over the species target as an impact of the tropic level changes correspond to the ecosystem changes and substitution of fish population from ?multi-species? fish resources. Study of distribution, abundance and catch of squid (Loliginidae) in the southern of Sunda Shelf waters was carried out based on daily monitoring data by enumerators (enumeration data) in 2018 of squid fishing gears (bouke ami, cast net and squid fishing) supported by 201 squid landing data at TPI Muara Angke (Jakarta) for the 2012-2018 period and TPI Kejawanan (Cirebon) for the 2008-2018 period. Field observations are intended to describe the characteristics of the fleet, fishing gear and operational aspects of capture. The results showed that the squid fishing area in the southern part of Sunda Shelf was widespread in the Java Sea and the South China Sea, but concentrated in the southern of Karimata Strait as indicated by the high intensity of catch (54% of the total fishing trips). However, in general the abundance of squid (indicated by the CPUE abundance index in kg / day) is almost the same, which is around 113-133 kg / day, while the abundance index (CPUE) in kg / trip looks different. Significant differences were also seen from the total catch of squid from the Karimata Strait which reached 55% of the total squid landings from the Shelf. The catch of squid that occurred until now shows an upward trend, this is as recorded in Muara Angke and Kejawanan. In catch composition, the percentage of squid also showed higher catches on trawlers (cantrang). Matters related to the management of squid fisheries as a diversification of fishing effort and diversion of target species are also discussed.

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.
