Abstract

Bidara upas (Merremia mammosa (Lour.) Hall.f.) is a medicinal plant, , that traditionaly use by Indonesian and Malaysian people. Regarding Indonesia Biodiversity Strategy and Action Plan released by The National Development Planning Agency, it is included in the extinct medicinal plant list (2003). As the center for plant conservation, Bogor botanical garden conducted vegetative propagation study on this plant by air layering, cutting, and tuber cutting. The aim to this study is to find effective for bidara upas which method is vegetative propagation. Air layering and cutting propagation modified by Rootone-F did not give any result, whereas tuber cutting propagation with GA3 gave positive result. Principally, propagation by tuber cutting modified by 50 ppm of GA3 dose gave the most rapid and highest uniformity on shoot emergence, the best on growing variables, namely average height of shoot growing, the number of secondary roots, the number and length of the primary roots. It cannot be concluded yet that propagation by tuber cutting modified by GA3 was the most effective. Hence, it is necessary to conduct another propagation studies of air layering and cuttings with more variants of treatments, especially Rootone-F dose.

Abstract

Studi kekayaan jenis herpetofauna (amfibia dan reptilia) telah dilakukan di dalam dan sekitar Taman Nasional Gunung Halimun pada bulan September 2001-September 2002.Metode yang digunakan untuk mengetahui kekayaan jenis adalah dengan pengamatan langsung,penyinaran menggunakan Iampu senter, tangkap langsung dan perangkap lem pada semua habitat herpetofauna di sepuluh lokasi penelitian, yaitu Citalahab, Cibunar, Cianten, Cigadog, Gunung Wangun, Gunung Bedil, Gunung Botol, Legok Karang dan Cikeris.Dari kelompok amfibia didapatkan 25 jenis, sedangkan untuk reptilia 31 jenis; yang termasuk dalam lima suku kodok,empat suku reptilia kaki empat dan empat suku ular. Enam jenis endemik Jawa dijumpai, yaitu Leptophryne cruentata, Microhyla achatina, Huia masonii, Nyctixalus margaritifer, Philautus vittiger, Rhacophorus javanus dan Spenomorphus puncticentralis.Hasil dari penghitungan koefisien indeks kesamaan Jaccard memperlihatkan bahwa sepuluh lokasi survai terkelompok menjadi dua grup besar, yaitu grup hutan dan grup area terganggu.Tipe vegetasi, habitat dan ketinggian tempat merupakan faktor-faktor ekologi utama yang mempengaruhi penyebaran herpetofauna di Taman Nasional Gunung Halimun.

Abstract

The objectives of this study are to test the pathogenicity of Streptococcus agalactiae and Streptococcus iniae in Nile Tilapia(Oreochromis niloticus) A challenge test was carried out in the Laboratory of Semarang Fish Quarantine. The method used in this study was the Completely Randomize Design(CRD) with three bacterial treatments Streptococcus agalactiae, Streptococcus iniae and control, three dose  107 ,108 , 109 with three replications for each treatment. The observed parameters include identification and reisolation of Streptococcus agalactiae, Postulat Koch test, survival rate (SR), and clinical symptoms. The result of this research showed that the survival rate of Nile Tilapia which has challenged by Streptococcus agalactiae was lower than that of Nile Tilapia which has challenged by Streptococcus iniae.

Abstract

Trypanosoma evansi known as trypanosomiasis causes or called surra in animals. Trypanosomiasis-associated death were generally due to severe anemia. Another report mentioned that a rapid death of mice can be attributed to the several reasons. One of those reasons is highly parasitaemia that leads to death of the host. However, there is another distinct report that high parasitemia in mice does not necessarily lead to anemia and clinical symptoms. This research was focused to study the relationship between trypanosomiasis-associated death with haematology profile, particularly the decrease of PCV (packed cell volume) value, anemia and virulence of T. evansi collected from several region of Indonesia. The experiments were performed by dividing mice into four groups. Three groups were infected by T.evansi according to the original isolates while another group were uninfected mice. Every two-day interval, all mice were observed their mortality and parasitaemia and also examined the PCV value and erythrocyte counts in peripheral blood. The experimental results shown that the degree of parasitemia in mice were not always related to mice mortality and anemia. Decreases of PCV value were related to the existence of parasitaemia but not with anemia. This study suggests that there is no relationship between the decreases of PCV value and anemia to the trypanosomiasis-associated death in mice.

Abstract

Green catfish is a commodity that is not only potential to be cultivated in the pond and in the floating net cages, but also easy to adjust to the artificial feed. The objective of this research is to evaluate the effect of different feed types (sinking and floating)on the growth performance of green catfish(Hemibagrus nemurus.One thousand and six hundred fingerlings averaging 2.50 g of 3 individual body weight were stocked in each of earthern ponds (10 x 8 x 1.2 m ). They were fed daily for four months with the same protein content (31%) and lipid (6%) diets. The feed was given in pelleted form at 8-4% of the total body weight. The result of this study showed that no significant difference (P>0.05) between different feed types. The sinking feed gave specific growth rate (2.35%), feed conversion ratio (2.49), protein retention (18.92%) and protein efficiency ratio 1.13 while the floating type gave the values 2.49%, 2.37, 20.48% and 1.21, respectively. Lipid retention of sinking feed (34.84%) is lower than that of floating type(48.39%).The survival rates ranged between 76.56-84.54%.Feed type sinking with protein content of 31% can be used in the rearing of fish in earthern pond.

Abstract

Program on the ability of agriculture to provide rice as a staple food tends to decrease with the reduced land area used for rice cultivation. improvement rice production should be directed to use  marginal land  as dry and acid land, where poisoning aluminium was seen as a constrain factor. Development of Aluminium (Al) tolerant variety is needed to increase rice production. This technology was environmentally friendly, cheaper and also easier for farmers adopted. The rice lines with broad genetics background which tolerant to Al toxicity has been produced by breeding program. The diversity of Indonesian local rice germplasm is a basic foundation on development of Al toxicity tolerant rice varieties. The purpose of this research was to analyze the genotype variety using 384 SNPs markers on selected Al tolerant rice lines based on bioinformatics approach. Based on the 384 SNPs markers, the total 26 selected  genotypes were clustered into 5 groups. Each group was having varied Relative Root Length (RRL), which was an Al tolerant parameter of phenotype. These groups were indicated for having different genes or QTL that were related to the Al tolerant character. The association analysis obtained 9 significant SNPs markers that can be applied as the molecular markers for assisting selection in breeding  program.
