Prevalensi Mikrofilaria setelah Pengobatan Masal 4 Tahun di Wilayah Kampung Sawah, Kecamatan Ciputat, Tangerang Selatan
Full text linkLimphatic filariasis is a target of global diseases elimination promoted by WHO to accomplish by the year of 2020.Until 2008, 316 out of 471 districts/provinces were mapped epidemiologically as endemic areas of filariasis. South Tangerang is one of the district reported as an endemic area of filariasis, with Mf prevalence ranged 1 – 2.4% determined from 2002 to 2009. Some factors play important roles in elimination program of filariasis, such as an appropriate diagnostic and its evaluation, and also annual program of Mass Drug Administration (MDA). In Ciputat area, South Tangerang district, the MDA has been conducted annually since 2009, and evaluation program by finger blood sample was also conducted in 2002 and 2009. Finding result showed prevalence 1.6% of Mf and 8 individu were clinically diagnosed as elephantiasis. Although the MDA has been conducted every year, but the evaluation has not yet been performed after 2009. The Study aimed to evaluate the MDA effect against mikrofilaria rate (Mf) and antigen circulation in perifer blood of people living near by the elephantiasis individu in Kampung Sawah area, Ciputat, South Tangerang. Periferal blood and blood vessel were collected at night from 08.00–10.00 PM. Peripheral blood were directly swab on slide or object glass to overnight preserve for giemsa stain in laboratory. After night preservation, the slide were then identified by microscope to detect microfilaria. The blood vessel were sentrifuged to collect the serum and performed rapid diagnostic test antigen antifilaria IgG4. Finding result of the study determined 95% Mf negative and 72.5 % negative of antigen anti-filaria IgG4. These finding showed that more than 70% of subjects were negative to filarial and its antigen circulation in the blood.This also indicates successfull program of 4 years MDA in this study area to eliminate parasite of filariasis

Full text linkCricket is commonly use as feedstuf for fishes and birds. However, most of market demand for this insect fulfilled by natural harvest. Since they could be an alternative nonconventional protein source for livestock industry, it is needed to develop methods for high cricket biomass production such as find their suitable food plants. During this research, Ciriling cricket (Grillus mitratus Burm.) was fed with various plants and mated with different sex ratio. Pakchoi (Brassica sinensis L.), papaya (Carica papaya L.), and carrot (Daucus carota L.) was combined with common commercial fed of cricket. Changes in food consumption, nymph mortality, body size, egg production, and egg hatching rates were measured in order to find best fed combination and sex ratio. The result showed that combination of standard fed with pakchoi preferred by cricket and produced best growth, highest egg production and egg hatching rates while ratio sex of 1:3 (male:female) produced highest number of eggs and best egg hatching rates
