Abstract

Research on the effect of soil moisture on agronomic characters, yield and nicotine content of Temanggung tobacco has been conducted in the Research Institute for Tobacco and Fibre Crops at Malang, East Java from March to October 2010. The treatment has been arranged in a Splitplot design with 3 replications. The experimental plot consisted of three types of soil: Complex Eutrudepts-Hapludalfs, Vitraquands, and Complex Dystrudepts-Hapludalfs. The subplot comprised 5 levels of soil moisturation: 60, 70, 80, 90, and 100% of field capacities. The results showed that the dry slice yield, content of nicotine, and agronomic characters of the Temanggung tobacco were affected by the result of interaction between soil moisture and type. The decreasing of soil moisture up to 40% from field capacity in the Complex Eutrudepts- Hapludalfs had decreased dry slice yield, nicotine content, plant height, root length, dry weight of plant, shoots, roots, stems, leaves, flowers, and suckers accounted for 54.3, 19.3, 33.7, 17.1, 74.1, 71.4, 82.3, 80.1, 54.3, 60.5 and 86.5% respectively, in the Vitraquands 72.7,20.2, 37.0, 13.2, 79.8, 78.5, 84.3, 80.7, 72.7, 63.3 and 87.8% respectively, and in the Complex Dystrudepts-Hapludalfs 74.2, 23.0, 39.6, 15.7, 79.3, 78.0, 83.6, 80.3, 74.2, 79.1 and 80.6% respectively.

Abstract

Study on the taxonomy and conservation status of Balsaminaceaein Java has been carried out. Based on the literature study, herbarium specimen deposited at Herbarium Bogoriense-LIPI (BO) and several field works in Java, there were two genera of Balsaminaceae found in Java namely, the monotypic Hydrocera triflora and the prolific Impatiens. The Impatiens consisted of seven species, i.e. Impatiens arriensii, I. chonoceras, I. radicans, I. javensis, I. wallerana, I. Platypetala and I. balsamina. Three species among them, Impatiens arriensii, I. radicans and I. Chonoceras were endemic and threatened in their habitat, while I. microceras has been extinct in the wild.The species Impatiens arriensiiwas transferred from the genus Semeiocardium.

Abstract

Lake Towuti is the largest lake in the Malili Complex covering the area of 560 km and 203 m in depth. Butini is an endemic and vulnerable fish species that consumed by the local people and have an important economic value. Various activities occured in the lake was thought to be the cause of decreasing fish populations.The objective of this study was to determine the growth and mortality of butini in Lake Towuti.This research was conducted in Lake Towuti for 12 months from Mei 2006 to April 2007.Fish samples obtained by using long lines with various number of hooks i.e. 8,10,12,14,and 16.Each depth (25, 50, 75, 100, 150, and 200 m) launched one long line unit in three zones (A, B, and C).Growth and fish mortality were calculated based on total length frequency data using FiSAT II software. The results showed that the longest size (46.20 cm) was the male found at a depth of -1,200(t-to)150 m in April in Zone C.The combined Von Bertalanffy’s growth pattern was of L(t)= 46,62 [1 - e ]. While the growth pattern for each male -0,950(t-to) -0,820(t-to) and female was L(t) =46,62 [1 - e ] and L(t)= 46,62 [1 - e ] respectively. The highest total mortality was found in Zone B (5.49 per year) occurred in female fish. The highest natural mortality was observed in Zone B (1.80 per year) occurred in male fish.The highest fishing mortality was recorded in zone B (4.08 per year) and found in female fish. The highest exploitation level was found in zone A (E = 0.76) recorded in female fish.Exploitation level of butini stock in Lake Towuti indicated over-fishing (E=0.56) recorded in Zone A.

Abstract

Isolation of endophytic fungi was done to find alternative microorganisms as antifungal agent against Fusarium oxysporum f.sp. cubense (Foc), causing panama disease (fusarium wilt) on Musa spp. The research objectives were 1) to isolate and identify endophytic fungi colonize cavendish (AAA) and rejang (AA) bananas growing on PT Natural Tropical Fruit (NTF) Plantation in East Lampung; and 2) to evaluate for their antagonistic activity against Foc under in vitro conditions. The results indicated 46 isolates of endophytic fungi that were isolated from leaves, saplings and petioles of cavendish banana; and leaves and petioles of rejang banana. The isolated endophytic fungi belonging to the group of Colletotrichum, Fusarium, Guignardia, Penicillium, Talaromyces and non sporulating endophytic fungi that were classified as unidentified isolate. Fourteen isolates (30.43 %) of those 46 fungi isolates tested, showed varying degree of antagonism to Foc. The best three isolates that have strong antagonistic activities were Talaromyces sp. 27-4 (M), unidentified 23-3/11 (B) and unidentified 26-5/K (L). Fusarium oxysporum 22-3/F (I), Penicillium sp. 20-2/H (J), Talaromyces sp. 27-4 (M) and unidentified 21-1/6 (A) inhibited the growth of Foc by producing both volatile and unvolatile metabolites. The strongest inhibition (53.17 %) by volatile inhibitory subtance was produced by F. oxysporum 22-3/F (I), while the strongest inhibition (65.98 %)by unvolatile inhibitory subtance was produced by Penicillium sp. 20-2/H (J).

Abstract

Research on gall (including field and laboratory observations and field collecting) have been conducted in the Mounts Gede Pangrano (MGPNP) and Halimun Salak National Parks (MHSNP). This research focused on gall shapes, host plant species, and parts of the host plants infected by galls. The result showed that there were 169 gall numbers in MGNP and 127 numbers in MHSNP have been collected. Distribution of plant species infected by the galls were rather same in the both conservation areas. In MHSNP seven families mostly infected by galls: Araceae, 4 species of 5 gall numbers collection in the family (=4/5), Elaeocarpaceae (5/5), Euphorbiaceae (7/9), Lauraceae (8/11), Moraceae (6/7), Melastomataceae (4/4) and Rubiaceae (9/12). In MGPNP the composition is only fairly different: Araliaceae (4/6),Euphorbiaceae (8/13), Lauraceae (9/12), Melastomataceae (5/6), Moraceae (13/22), Myrtaceae (9/11) and Rubiaceae (6/13). At least 23 gall shapes were found in both locations. The most common shape of galls found in MGNP was irregular, while in MHSNP was globular.Galls were mostly (90%) collected from leaf including peduncles and leaf venations. The other parts included twigs, branches, stems, flowers,and fruits. The most common insect found investing galls (i.e. insect gallers) was the midges (54.4%) followed by mites (18.5%), psyllids (11.1%), thrips (6.3%), coccids (1.9%), and aleurodes (1.9%).

Abstract

Kecondang or Taka (Tacca leontopetaloides), a member of Taccaceae, is one the carbohydrate alternatives to rice which can be developed in coastal area. With the global warming, the sea level has increased and small islands are more isolated. The people who lives in these islands should depend on their bioresources.As Taka inhabits coastal area, the development of this plant becomes critical.A total of 65 accessions of Taka from 9 provenances in Indonesia (Sukabumi, Madura, Kp.Siung (Yogyakarta), Gn. Kidung (Yogyakarta), and the small islands in Karimun Jawa namely Nyamuk, Katang, Cendekia, Kumbang, Seruni islands) were characterized using six ISSR markers [GSGG (TG5)T; CCAG(TGG)3TG; GGAG(TGG)3TG; BDBT(TCC4); (AC)8C; (AG)8G]. The scoring of the fragments resulted in 55 (69.6%) polymorphic bands. The size of the bands varied from 150bp to 1,6kb. The 65 accessions of Taka made several clusters according to their provenances. The range of individual genetic dissimilarity was from 0.012 to 0.186. The results showed that amongst nine population studied, Gn. Kidul, Yogyakarta population has the highest level of genetic variation with mean values of Na = 1.3544±0.4814, Ne =1.1784±0.3025, PLP = 35.44% and He = 0.1094±0.1681. Whereas, P. Nyamuk, Kep. Karimun Jawa population has the lowest level of genetic variation with mean values of Na = 1.0759±0.2666, Ne = 1.0523±0.2163, PLP = 7.59% and He = 0.0275±0.1097.

Abstract

Avian influenza virus subtype H5N1 outbreak has become endemic in Indonesia since 2003. The disease does not only cause immense economic losses but it also leads to significant fatality of human being. The existence of traditional markets including live bird trading is suspected to play important role in the spreading and evolution of the virus. The objective of this study was to identify the circulation of H5N1 virus at traditional markets of East Java in 2012 by using reverse transcriptase polymerase chain reaction (RT-PCR) test and virus isolation. As results, this study detected the presence of the H5N1 virus circulating in Gresik, Mojokerto, Lamongan and Surabaya in both of live birds and environmental samples. The successfulness of virus isolation indicated a potential transmission to other hosts, including to human. This study suggests that the improvement of the poultry trading system at traditional markets by implementing sanitation, hygiene and biosecurity is necessary to reduce the burden of virus contamination at the market environment.

Abstract

Two quantitative traits, cherry and green bean characters are the important phenotypic selection in coffee breeding practice. The important well-known character from coffee markets is cherry and bean size. In this study, 43 genotypes of coffee were collected from four districts in East Kalimantan i.e. Kutai Kertanegara, Kutai Timur, Berau dan Paser Utara. The objective of this study was to identify cherry and green bean character using quantitative trait locus (QTL) molecular marker, genetic variation from developed alleles, cluster analysis and association analysis of molecular marker, and phenotype observation. Based on polymorphic information content (PIC) of primers used in this study, the genetic variation was low. Based on cluster analysis, two major groups were identified. The first group corresponds to Arabika that consisted of 3 districts, Kutai Timur, Berau and Paser Utara. The second group correspond to Robusta mostly from Kutai Kertanegara.Significant association of primer markers M480 and M312 with QTL has suggested that they can be used as specific primers linked to size of cherry and green bean.Furthermore,they were potential marker assisted breeding in coffee breeding program.
