"Infeksi Soil Transmitted Helminth (STH) memiliki pravelensi yang cukup tinggi di wilayah Indonesia. Salah satu resiko paling tinggi infeksi menyerang anakanak sekolah. WHO telah mencanangkan program eliminasi infeksi STH di Dunia termasuk di Indonesia hingga tahun 2020 dengan mengembangkan metodemetode diagnosis infeksi STH. Metode diagnosis harus memiliki t ingkat sensit ifitas dan spesifitas yang tinggi dalam mendeteksi keberadaan telur pada pemeriksaan sampel feses. Salah satu metode yang tengah dikembangkan yaitu Metode FLOTAC dan Mini FLOTAC. Penelitian ini bertujuan untuk membandingkan metode FLOTAC dan Mini FLOTAC dalam mendeteksi sampel feses.
Hasil penelitian menunjukkan analisis statistik metode Flotac dan Mini FLOTAC tidak memiliki perbedaan signifikan dalam hal sensitivitas, spesifisitas, hasil rerata positif maupun intensitas telur sehingga dalam implememtasinya, metode Mini FLOTAC dapat dijadikan alternatif untuk melakukan studi epidemiologi di lapangan karena lebih praktis dan minimnya biaya yang dibutuhkan.

Soil Transmitted Helminth (STH) Infect ions having the relat ively high prevalence in Indonesia. The highest rist of infect ion attacks School Aged Children. World Health Organization (WHO) has init iated eliminat ion and control programme of STH infect ions around the world including Indonesia by developing deiagnosis method of STH. A method should have the high level of sensit ivity and specificity which could detect the presence of STH?s eggs in sample examinat ions. There are new mult ivalent methods has been developed such as Flotac and Mini Flotac. This study aimed to compare both of method in detecting eggs inside the samples to get the which method has higher value of sensit ivity and specificity.
The results showed that Flotac and Mini Flotacd has no significant differences of sensit ivity, specificity, mean of positive results and intensity of eggs. So that, in implementation, Mini Flotac is a quiete realiable to use in epidemiology study and less cost to detect STH infections.

"ABSTRAK

Telah dilakukan penelitian yang bertujuan mengetahui potensi hepatoprotektif madu PS terhadap kadar alkali fosfatase (ALP) mencit (Mus musculus L.) jantan galur DDY. Dua puluh empat ekor mencit jantan dibagi ke dalam 4 kelompok hewan uji, yaitu kelompok kontrol normal (KK1) yang diberikan akuades dan minyak kelapa; kelompok kontrol perlakuan (KK2) yang diberikan akuades dan CCl4; serta 2 kelompok perlakuan (KP1 dan KP2) yang diberikan madu PS 10% dan 20% selama 14 hari berturut-turut, kemudian CCl4 2 jam setelah pemberian madu terakhir. Darah diambil 24 jam setelah injeksi CCl4. Kadar ALP diukur dengan metode kolorimetri. Hasil uji anova satu arah (P<0,05) menunjukkan adanya pengaruh nyata pemberian madu PS terhadap kadar ALP semua hewan uji. Dibandingkan kadar ALP KK2, kadar ALP KP1 lebih rendah 30,5% dan KP2 lebih rendah 52,9%. Namun, uji LSD (P<0,05) menunjukkan hanya kadar ALP KP2 yang tidak berbeda nyata dengan KK1. Berdasarkan hasil tersebut, disimpulkan bahwa potensi hepatoprotektif madu PS 20% lebih besar dibandingkan madu PS 10%.


ABSTRACT

The study has been conducted to know the hepatoprotective potency of PS honey administration on male-DDY mice’s alkaline phosphatase level of blood plasma. Twenty four male mice were divided into four groups, namely normal control group (KK1) which was administered with aquadest and coconut oil; treatment control group (KK2) which was administered with aquadest and CCl4; and two treatment groups which was administered with PS honey 10% (KP1) and 20% (KP2) within 14 consecutive days and three groups (KK2, KP1,and KP2) were injected with CCl4 on the 14th day. Alkaline phosphatase was measured based on colorimetry method. One-way anova test (P<0,05) showed that alkaline phosphatase levels were significantly different. Compared with KK2, the alkaline phosphatase levels of KP1 and KP2 were 30,5% and 52,9% lesser than KK2, consecutively. However, LSD test (P<0,05) showed that only alkaline phosphatase level of KP2 was not significantly different. In conclusion, dose 20% of PS honey is more potential on hepatoprotective than those of 10%.

"ABSTRAK
Orangutan is the Asian representative of the great apes. Its present range is confined to dwindling areas on the islands of Sumatera (Pongo abelii) and Borneo (Pongo pygmaeus) (Rijksen & Meijaard, 1999). Orangutans are arboreal (Rijksen, 1978; Galdikas, 1978), frugivorous (MacKinnon, 1974) and live semi-solitary in fission- fusion societies (Delgado & van Schaik, 2000). Ketambe, one of the major orangutan sites, supports a population density of 3-5 ind/km2 . Ketambe Research Center, which is based in Gunung Leuser Ecosystem, was run since early 1970. There are at least six families of orangutans living in the research areal of 450 ha, including the offspring of the ex rehabilitation orangutans. Orangutans in this area have been studied since 1971, where many behavioral and ecological studies have been conducted.. One of the most important studies identified matrilines within Ketambe based on genetic analysis (Atmoko, 2000) Female orangutans in Ketambe tend to be philopatric which means that they remain in their natal or birth groups. This condition is the result of intense competition among individual orangutans over food patchs because they often form dominance relations when meeting in the same food patch. Dominan ranking of ex-rehabilitation orangutans, based on a liniear index of responses in the context of displacement at a food patch, tends to be lower than those of wild orangutans. Orangutans travel and forage to find food patches within their habitat. By using software GIS Arc View 3.3, Day Journey Length (DHL) adult females including ex-rehabilitation female orangutan ex-rehabilitant is known to be 37-2.106 meters with an average between 437-795 meter. The matrilinial relationship between individuals influence each other in foraging and competition to form home ranges, especially for females. Orangutans matrilines tend to have overlapping home ranges between 46,66% - 97,07%)."
