Abstract

Abstract. Artificial blood-feeding using the parafilm-M membrane can be used as an alternative solution andsubstitute live animals as a source of blood. This method is not only be used for blood-feeding but also to infectthe dengue virus (DENV) to mosquitoes. This study was aimed to determine the effectiveness artificial bloodfeeding using parafilm-M membrane in Aedes mosquitoes originated in Indonesia and determine the positivityof mosquitoes infected by Indonesia DENV-1. DENV-1 was isolated from patient and propagated in Vero cellculture. The feeding was done in cardboard cups after mosquitos have been starved for 4-17 hours before beingfed with human blood. A conical 50ml tube was prepared, and a hole was created in the tube lid. The tubeopening was covered with parafilm. Glycerol was added into conical tube and heated in water bath for an hourat 55oC. A mixture of blood and DENV-1 was made with concentration of 10%. Detection of DENV in bloodfedmosquitos was carried out by using Simplexa Dengue Real-Time RT-PCR assay. The results showed thatthe prevalence of blood-fed mosquitoes reached 66.67% with fasting period for 17 hours. Blood feedingmosquitoes are affected by duration of fasting period, blood-feeding time, and attractants from human skinrubbed into parafilm-M membrane. The prevalence of blood-fed Ae. aegypti infected by DENV was 20.83%.This study provides information on the effectiveness of artificial parafilm membrane blood-feeding in alaboratory setting that will be useful for vector control study in Indonesia.

Abstract

Cagar Alam Bantarbolang, Pemalang, Jawa Tengah memiliki keanekaragaman yang tinggi baik itu flora maupun faunanya Salah satu indikator kestabilan ekosistem yang baik di suatu ekosistem hutan yaitu adanya keanekaragaman semut. Semut berperan penting dalam ekosistem terestrial sebagai predator, herbivor, detrivor, dan granivor. Semakin tinggi keanekaragaman semut, semakin tinggipula tingkat kesehatan hutan tersebut.Tujuan dari penelitian ini adalah mengetahui keanekaragaman, kemerataan, dan dominansi spesies semutdi Cagar Alam Bantarbolang, Pemalang, Jawa Tengah. Penelitian ini menggunakan metode survey dengan teknik pengambilan sampel perangkap jebak (pitfall trap) denganukuranplot1 m x 1 m sebanyak 8 plot. Pada masing-masing plotdibuat 4 subplot untuk pemasangan pitfall trap yang berisi air gula.Semut diambil dari gelas plastik yang berukuran diameter 7,5 cm dan tinggi 10,5 cm yang ditanam setengah dari tinggi gelas plastik dari permukaan tanah, dipasang setiap minggu selama satu bulan kemudian didokumentasikan dan dilakukan identifikasi. Data yang didapat dianalisis menggunakan indeks keanekaragaman Shannon-Wiener dan Indeks dominansi. Hasil penelitian menunjukan bahwa ditemukan 982 individu yang berasal dari 1 familia yang terbagi menjadi 4 subfamilia. Adapun tingkat keanekaragaman semut dari ordo Hymenoptera dan familia Formicidae yang ada diCagar Alam Bantarbolang, Pemalang, Jawa Tengah menunjukkan nilai indeks keragaman Shannon (H’) berkisar antara 1,394 - 1,855, indeks kemerataan Evenness (E) berkisar antara 0,448 - 0,7101, sedangkan dominasi Simpson (D) yaitu sebesar 0,6363 - 0,8125.

Abstract

Kupu-kupu adalah serangga yang termasuk dalam Ordo Lepidoptera, artinya serangga yang hampir seluruh permukaan tubuhnya tertutupi oleh lembaran-lembaran sisik yang memberi corak dan warna sayap kupu-kupu. Keanekaragaman dan Kelimpahan kupu-kupu di pengaruhi oleh faktor lingkungan seperti intensitas cahaya matahari, temperatur, dan kelembapan. Penelitian ini bertujuan untuk mengetahui keanekaragaman dan kelimpahan kupu-kupu di Cagar Alam Bantarbolang, Jawa Tengah. Data yang di dapat di analisis menggunakan indeks keanekaragaman indeks keanekaragaman Shannon-Wiener, indeks kemerataan Shannon-Evenners, dan Indeks dominansi. Hasil penelitian yang telah dilakukan menunjukkan bahwa ditemukan 359 individu dalam 6 familia. Keanekaragaman tertinggi yaitu pada jarak 0 m (H’ = 2.760; E: 0,752). Kelimpahan tertinggi pada jarak 0 m dengan jumlah individu sebanyak 192. Keanekaragaman tertinggi pada jarak 0 m di tepi hutan, sedangkan keragaman terrendah pada jarak 150 m di dalam hutan. Keanekaragaman kupu-kupu didominasi oleh H. glaucippe dari famili Piridae sebanyak 64 individu. Faktor lingkungan yang paling mempengaruhi keanekaragaman dan kelimpahan kupu-kupu adalah intensitas cahaya matahari. Kata kunci: Kupu-kupu, Keanekaragaman, Kelimpahan, Cagar Alam Bantarbolang

Abstract

Gurami (Osphronemusgouramy Lac.) Is a type of freshwater fish that is widely cultivated by the people of Indonesia. The high price of gouramy is a measure of consumption and the meat is tender and tasty. In Tasikmalaya, carp farmers in the cultivation of gouramy seeds are still experiencing problems. Gouramy seeds raised to adult size experience high mortality due to ectoparasites. One of the ectoparasites was Trichodina sp. Research has been conducted aimed at 1. Knowing the prevalence of gouramy seeds that were attacked by Trichodina sp. obtained from fish farmers in the village of Rajapolah, Tasikmalaya Regency and 2. Knowing the morphometric variations of Trichodina sp. found in gouramy seeds obtained from fish farmers in Rajapolah Village, Tasikmalaya Regency. The method used in this study is a survey method. Seed gourami aged 2 weeks is use as a sample. Isolation and identification were carried out by making a range preparation and painting using a 2% AgNO3 solution. The results found that the prevalence of 88% or high, while the results of the examination of morphometric variations found 4 species of trichodina sp. namely T. Pediculus, T. Nigra, T.heterodentata, and T. Acuta.Keywords:Trichodina sp., Gourami, morphometric variations, abundance, Rajapolah

Abstract

The main purpose of this study are to compare gastrointestinal worm species founds in goats, to compare prevalence and intensity in goats under intensive and semi intensive rearing system and to compare sex-wise and age related prevalence and intensity of gastrointestinal worms in goat. This research was conducted in intensive and semi intensive goat farms in Desa Klareyan, Kecamatan Petarukan, Pemalang using survey method with purposive random sampling technique in November 2020. Gastrointestinal worms species found in goat feces under intensive rearing system are Strongyloides sp., Haemonchus sp., Oesophagostomum sp., Trichostrongylus sp., and Ascaris sp. while species founded in goats under semi intensive rearing system are Strongyloides sp., Haemonchus sp., Oesophagostomum sp., Trichostrongylus sp., Ascaris sp., Moniezia expansa, Moniezia benedeni, Fasciola sp., And Schistosoma sp. The intensity of gastrointestinal worm eggs in goat under intensive rearing system was 1184.44±1743,28, its higher than the intensity in goats under semi intensive rearing system which has 1109.50±1573.73 (P> 0.05). The prevalence of gastrointestinal worm infestations in goats under intensive rearing system is 90%, lower than the goats under semi intensive rearing system which has 100% prevalence (Sign. 0.147). Gastrointestinal worms prevalence and intensity in male goats is lower than female goats (Sign. 0,189; P>0,05), while Gastrointestinal worms prevalence and intensity in lamb goat is higher than young goat and adult goat (Sign. 0,241; F<0,05).

Abstract

The controlling of fascioliasis has not been satisfying so far, since the effort of breaking off the fluke life cycle often leads to resistance. The resistance is due to the synchronization between the parasites and their snail host and high infection ability of the parasites enabling them to finish their life cycle. Ultraviolet irradiation provides alternative approach possibly applied to cope with the resistance. The objectives of this research were to know the ability of F. gigantica miracidium in infecting Lymnaea sp. at various ages and  to determine time exposure of ultraviolet (254 nm) effectively reducing the ability of miracidium infection. The results indicated that susceptible age of Lymnea javanica is five weeks old, while the most effective time exposure of ultraviolet (254 nm) in weakening  the ability of Fasciola gigantica miracidium infection to L. javanica is 60 seconds (P < 0,05).  At the moment the study on reinfection effect of F. gigantica miracidium on the immunity of L. javanica is still in progress.
