Bread fruit (Artocarpus communis Forst) is one of tropical fruit, which has a high contain of carbohydrate.In certain area, it becomes an alternative staple food when the main staple foods are scarce.The amount of carbohydrate in breadfruit is almost the same with the one in sweet potato, but it is higher than in potato. The main constraint of the development of breadfruit is the limited of seedling availability.Tissue culture technique has been known for its excellent result for plant propagation, because this technique has ability in producing seedling in a large quantity, in uniform growth rate and in a relative short time.The experiment was conducted at Cell Tissue Culture Division, Indonesian Center Agricultural Biotechnology and Genetic Resource Research and Development (1CAB1OGRAD) from February 2003 until December 2004.There were some steps experiments with series of combination medium as treatments. The first steps was shoot multiplication at Sk-2 medium with WPM + BA (0; 0,5; 1,0; 1,5 and 2,0 mg/1) + Thidiazuron (0; 0,4 mg/1);The second step was elongation shoot at Sk-3 with WPM + kinetin (1,2 and 3 mg/1) + GAa(0 and 5 mg/1), and the third was root initiation and proliferation, by comparing WPM + IBA (0, 2, 4 and 6 mg/1) + charcoal (0;0,5 %) and WPM (1; 0,5) + BA (0; 1,5 and 5 mg.l) or NAA (1,2 and 3 mg/1). For the step of acclimatization, soil and compost were used in comparison of (1;1 and 1:2).The result showed that the best media for shoot multiplication of breadfruit was WPM + BA 2 mg/1 + TDZ 0 4 with shoot number of 15,5., while the best media for shoot elongation was WPM + Kinetin 1 mg/1 + GA, 5 mg/1.WPM + IBA 3 mg/1 was the best formula for root proliferation with the highest root number about 6.5 and percentage of shoot producing root about 60%. For acclimatization, soil and compost in combination of 1:1 was the best media for planlet of breadfruit with the success rate about 70%. Charcoal is not necessary in root initiation and proliferation.

Bali myna (Leucopsar rothschildi Stresemann, 1912) was reported as an endemic bird from western part of Bali Island, and also as endangered species.The species lived in the lowland forest and used tree holes made by other animals as their nests.Besides L.rothschildi, there were two other species of birds found using the holes as their nest in the study site, namely Black-winged starling(Sturnus melanopterus (Daudin, 1800)) and Javan myna (Acridotheres fitscus (Wagler, 1827)).This paper deals with result of research on the competition of those three species of birds in obtaining tree hole for nesting, was carried out in West Bali National Park, Bali. Data demonstrated that there were no differences in the size of nest for the three species of birds, Javan myna lived in the habitat of coconut garden where Bali myna did not occupy it, and the habitat of Black-winged starling was overlapped with Bali myna, but Bali myna preferred living in denser vegetation. The reproduction of the three species of birds were dependent on the occurrence of other birds species belonging to Picidae and Capitonidae who were able to make holes on trees.

TEKNOLOGI PENGAIRAN DAN PENGOLAHAN TANAH PADA BUDIDAYA PADI SAWAH UNTUK MITIGASI GAS METANA (CH4) Naharia, Orbanus; Saeni, M Sri; Sabihan, Supiandi; Burhan, Harris

Global warming that caused by green house effect is one phenomena where short wave sunlight radiation penetrates the atmosphere and changes to become long wave on earth surface, when reaching the earth surface, a part of the wave reflected to atmmosphere,however not the entire reflected wave will be released to outer space; greenhouse gases layer in the atmosphere will reflect part of the wave to the earth surface resulting in increasing surface temperature.According to data from National Communication in 1997, agriculture and husbandry sectors give large contribution for the increasing green house gases particularly CH4 produced from rice field cultivation.Due to the reason, research for "irrigation and soil cultivation technology on rice field for mitigation of methane (CH4) gas emission in dry season" has been conducted. The objectives are to analyze different effect of continuously flooded (5 cm), intermittent irrigation and saturated water condition (0 - 1 cm water level) on CH4 emission, to analyze effect of soil cultivation and zero tillage on CH4 emission and to analyze interaction between irrigation treatment and soil cultivation on rice field for CH4 emission.The result indicated that type of irrigation systems affect the CH4 emission on rice field cultivation. Intermitten irrigation system shows able to suppress CH4 emission 56.34%, while saturated water condition system is 54.61%. Type of soil cultivation also affects the CH4 emission. Soil preparation with zero tillage by touchdown reduced CH4 emission by 25.55%, while by gramoxone the reduction was 48.84%. The lowest CH4 emission was under saturated water condition system combined with zero tillage treatment. Combination saturated water condition system by touchdown and zero tillage treatment is resulting emission in amount of 61.54 kg/CH4/ha/season. The combination of saturated water condition system by gramoxone and zero tillage treatment is resulting emission in amount of 88.12 kg CH4/ha/season.Combination of all treatment has no significant difference on rice yield.

Gynura pseudo-china (L.) DC./umbi dewa (Asteraceae/Compositae), is a species that produce tuber, the whole parts of plant especially the tuber is used as medicine. Extract of the whole plants of "umbi dewa" contains iridoids, terpenyl coumarins spirostanol steroids, pyrolizidines, purines, pyrimidines and chromanes, which has inhibit glucose cerum effect.Industrial usage of the plant requires continuos supply of materials which in turn necessitate its cultivation and planting materials.Planting materials can be produced efficiently by micropropagation technique. This objective of the study was to evaluate the culture respond to the plant growth regulator (PGR) treatments. The experiment was designed with completely randomized designed (CRD) and micropropagation result indicated that proliferation of shoots were optimum in the growth medium supplemented with N6-Benzyladenine (BA) 2 mg/l and adenine sulphate 15 mg/l, BA 4 mg/1 and adenine sulphate 10 mg/1 in combination.Inclusions chlorocholine chloride/chlormequat (CCC) and higher sucrose had positively effect on proliferation microtuber in growth medium supplemented with BA 2mg/l without adenine sulphate. Acclimatization stage and planted to the soil were successful, almost whole (95-96%) plants were survive.

The experiment was conducted to evaluate the growth of Pangasius djambal which were fed with different dietary protein levels.Fifteen fingerlings averaging 6.13 g individual body weight were stocked in each of 9 fibreglass tanks filled with 30 liters of water.They were fed daily for 42 days with diets containing 30%, 35% and 40 % protein. The feed was given in crumbled form at 7% of total biomass,4 times a day and contains 2600 k.cal.DE/kg feed.The result showed that feeds with different protein content gave qudratic respon curve. Maximum values for protein retention (36.65%) were obtained with feed containing 34.14 % protein.The feed with 35% protein content gave the lowest (78.12%) lipid retention. Feed conversion ratio (1.31-1.36), daily growth rate(3.64-3.82%) and protein efficiency ratio (2.05 - 2.29) were not different among treatments.The survival rates 100% were the same for all treatments.It is suggested that feed with protein content 35% and 2600 K. cal DE/ kg feed can be used in intensive culture of Pangasius djambal fingerlings to attain the best growth and suvival rate.

The ulin or so called vernacular name kayu besi (Eusideroxylon zwageri T.et.B.) is one of the the important timber in East Kalimantan (East Borneo).However, there are some problems in the regeneration of this species. The research on propagation of ulin was carried out in Treub Laboratory, Research Center for Biology. The research consist of two experiments The research consisted of two experiments.The first experiment seeds which was treated in order to stimulate the germination and the second experiment by treating the mixture between 1BA and vitamin C for stimulating root cutting.The best result of seeds germination was recorded 90%,which the seeds were treated by removing the whole seedcoat and then by exposing to the sunlight for 5 hours The seed itself began to germinate 7 weeks after sowing.Meanwhile, the control no germination et all until 28 weeks.The best result on cutting was indicated by treating with the combination of IBA 10 mg/1 and vitamin C 50 mg/1 which was achieved the highest rooting 100%,although without hormone treatment only resulted 33.3% rooting.
