Abstract

Orangutans are solitary animals from the Pongidae family. There are three sub-species of Bornean orangutans, i.e. Pongo pygmaeus wurmbii, P. pygmaeus pygmaeus and P. pygmaeus morio, all of which are highly endangered. Orangutans carry out several daily activities such as eating, moving, resting, and nesting in the tree canopy. However, it has yet remains unknown on how their behaviours vary with tree height. This study aimed to determine the frequency of presence, daily activities of orangutans, and vertical space utilization in orangutan activities in the natural habitat of the Panti Branch Research Station, Gunung Palung National Park. This study used the Focal Animal Sampling method with a two minute time interval for ± 12 hours and was studied for over six months. The focal orangutans whose activities were recorded during the study consisted of 12 individuals divided into 3 age groups, namely the adult, adolescent, and juvenile age groups. The results showed that the daily activity of orangutan was observed on 36 species of trees with the greatest frequency found on Garcinia sp. and Syzigium sp. accounted for33% each. The female orangutans were found to be more dominant in feeding activities (3.93 per day), while male orangutans spent more time for resting activities (4.56 hours per day). The utilization of vertical space in young male orangutans took place in tall trees and eating activities occurred at an altitude of 33.6 m. On average, teenage female orangutans choose tree to make their nests in trees 30 m high.

Abstract

One way to support the increase of aquaculture production is to produce superior strains of growth. Carp as one of the potential for these commodities only rely on local strains which have had a decline in quality. For that, the effort to generate superior growth of carp need to be done. One way to do that is by hybridization. We carried out reciprocal crosses of 4 strains of carp Rajadanu, Subang, Majalaya and Kuningan to obtain 16 new strain candidates. Furthermore, growth test was conducted to find out the best candidate of the absolute and specific growth parameters. From these results, it was concluded that the absolute growth in length, weight, and the highest biomass obtained by crosses of SB x RD, the highest length and weight Specific Growth Rate obtained by crosses of RD x MJ. For the highest degree of survival is at the intersection of KN x SB, whereas the highest survival rate in the use of female parent KN. In the dominant male of female survival is the parent SB. The biggest positive heterosis character length growth values obtained by crosses of SB x RD. For the highest weight growth heterosis values obtained by crosses of SB x MJ. On the character of hatching, the highest positive heterosis values obtained by crosses of SB x MJ. The degree of survival of the highest heterosis values obtained by crosses of KN x MJ. On the character of the highest positive heterosis values of biomass obtained by crosses of SB x MJ. As for the character length SGR highest positive heterosis values obtained by crossing two directions of RD and SB. And for the character weight Specific Growth Rate, the highest positive heterosis values obtained by crossing two ways KN and MJ.

Abstract

Star fruit(Averrhoa carambola L.)is considered originally from Indonesia. In-vitro propagation of star fruit- is a very few.Propagation of star fruit through leaf,seedling and cotyledon culture have succeeded but its propagation through root culture has not been reported.This experiment was carried out to know the responses of star fruit root culture.Roots of young seedling of star fruit grown in-vitro were cut and cultured on one-halfMurashige & Skoog (MS)medium with or without addition of1 mg/16-ben^ylaminopurine (BA).The response of explants were determined by age of the seedlings which young seedlings were more response than the old ones. Somatic embryogenesis occurred on explan star fruit roots after 9 weeks incubation. Explants produced little callus on excised roots andprofused multiple shoots on MS with addition of BA, whereas explants only produced a few shoots without any producing callus on medium MS without any addition ofBA. This indicated that star fruit can be propagated from its root which is a very rare success of the other plant regeneration from root culture.

Abstract

The Lake Sentani has problems. Firstly, high of erosion number i.e. 94.52 ton/ha/year of which the value is higher than erosion tolerance at average 25 ton/ha/year.Secondly, high concentration of chemical pollution such as Cu (0.0201- 0.1081 mg/L) and Zn (0.21 - 0.36 mg/L) which these values are above water quality standard approved by the government as ruled in PP 82 Tahun 2001 about the management of water quality and water pollution. Therefore research and management are needed to find solution for the sustainability of this lake. The aims of this research is to be acquainted with carrying capacity of Lake Sentani through analyzing 1) the pollution load, and 2) the assimilation capacity of Lake Sentani aquaculture. The collected information is important for future aquaculture environmental management and conservation. Result shows that the pollution loads from river are obtained as follows (ton/month): TDS (441.806 to 775.287), BOD (3.510 to 7.801) and COD (7.737 to 16.055).The assimilation capacities from lake are obtained as follows (ton/month): TDS (12.18494), BOD (11.31973) and COD (122.4184).The number of pollution loads (TDS, BOD and COD) are under the assimilation capacity.

Abstract

Papaya is climacteric fruit. As the other climacteric fruit, papaya has hight speed ripening, so papaya fruit can not stored in long period. Genetic enginering is one alternative technology to solve the problem by introducing antisense oxidase ACC gen to the papaya plant genome to get delay ripening characteristic. Success of genetic enginering technology depend on plant regeneration system.There were two ways of plant regeneration: organogenesis and somatic embryogenesis. The aim of this experiment was to induce root formation of papaya planlet which trasformated by ACC oxidase antisense gene.The former experiment showed that explant which transformated by ACC oxidase antisense gene can regenerated to be shoot/planlet with P6 medium.But when the shoot transferred to root induction medium the root was difficult to formed, callus was formed at the base of shoot, the leaves turn to yellow and fall down.Many media formulations were tried in this experiment with different basic medium for root induction and development.MS (1, Vi)\ DKW (1, 'A) and WPM (1, Vi) were used as basic media combined with sucrose (2 % and 3 %) and plant growth regulators (kinetin, IAA, and paclobutrazol) adding with some organic compound. Result of the experiment showed that MS Vi + paclobutrazol 0.5 mg/1 induced root formation 80 %, inhibited callus formation and decreased yellowing and falling of the leaves.

Abstract

Giant gouramy is a native fish to Indonesia and widely distributed in Sumatra, Kalimantan and Java. The aim of this study was to characterize the phenotype and kinship of Giant Gouramy from crosses between strains Jambi, South Kalimantan, and West Java (Tasikmalaya). This Research was conducted at the Giant gouramy Hatchery of Research Institute for Fish Breeding, Sukamandi, West Java. Analysis of morphological diversity of all crosses between varieties performed through morphometric measurements that have been determined based on a point benchmark of 16 haracteristics of the truss. Measurement data of each character crosses which have beenrelativized by standard length were analyzed using discriminant analysis and hierarchical cluster analysis. The result showed that Giant gouramy has low diversity coefficient values, ranging from 4 to13%. The highest coefficient of variance (CV) was found in the character of C3 (the tip of the anal fin-base of the tail fin), which ranges from 18-33% and the lowest in the character B5 (the base of the pelvic fin-tip of the dorsal fin) in the range of 2-4%. Based on discriminant analysis, males Giant Gouramy have more character differences than females. The closest kinship relationship is in hybrid of Tasikmalaya and Jambi (TJ) strain with of South Kalimantan and Tasikmalaya ( KT) which has a similarity level at 89.41%. However, the farthest kinship is in pure line of Tasikmalaya (TT) and Jambi (JJ) with the three other strains namely South Kalimantan and Jambi (KJ), Tasikmalaya and Jambi (TJ) and South Kalimantan and Tasikmalaya (KT) with a value of similarity of 53.93%.
