Abstract

African catfish, namely lele dumbo, is an economically important fresh water fish in Nusa Tenggara Barat. There are three strains of African catfish that are well distributed among farmers. Genetic information of three strain catfish stocks is needed in order to sustain their development program. Genetic variations of the three strains of catfish, i.e. Sangkuriang, Masamo, Paiton has been evaluated using RAPD markers. DNA genome was extracted using phenol-chloroform methods. DNA was amplified using 20 primers (OPA 1 – 20). The results showed that three of the 20 primers have good amplification products. There was no significant genetic differences among three strains of catfish analyzed (P>0.05). Genetic variation of three African catfish stocks ranges from low to middle value. The highest genetic variation is found in strain Masamo with heterozygosity of 0.273 (with 70% polymorphism loci), followed by Sangkuriang 0.189 (60%) and Paiton0.147 (40%). Hybrid candidates of Masamo-Sangkuriang have eterozygosity ranges between 0.256 - 0.306 (with 66.6 7 – 73.77% polymorphism loci). Strain Masamo and Paiton has more close genetic relationship than among the both and Sangkuriang.

Abstract

A quantitative study of epiphytic plants was conducted at the logged over forest in Kiyu, Meratus Mountain, Hulu Sungai Tengah, South Kalimantan. This study used a plot of 10 m x 500 m (± 0,5 ha), and divided into 50 subplot of 10 m x 10 m. The results showed that there were nine species of six genera from three families of epiphytic plants found within the studied plot, with A grostophyllum bicuspidatum as the dominant species. The diversity index (H’) was of 1,85. The diversity of epiphytic plant in these plots was well represented based on the results of analysis of species area curve. Spatial distribution pattern of all epiphytic species was homogeneus, except for A. bicuspidatum. The number of epiphytic host plants observed was 22 individuals from six species of six genera, and five families, with Saurauia nudiflora (Acthiniaceae) was the dominant host plant.

Abstract

Forest land converted into palm oil plantations have caused habitat fragmentation of elephant and land degradation. These lead to land use conflict between human and elephant. The conflict often caused the elephant killed and destructed agricultural land. The study was aimed to estimate potential use and carrying capacity of elephant habitat. Data collection of undergrowth vegetation were analyzed using twelve square plots of 1 x 1m, the distance between the plot of 50 m, tree vegetation of seedlings size 1 x 1 m, saplings 5 x 5 m, and trees 20 x 20 m, the distance between the plot of 200 m and of 1000 m lenght. Vegetation used as elephants feed were observed using purposive sampling and systematically procedure. The analysis showed that biomass of plants producing elephant fodder in Tambang Besi were of Cyperus rotundus (3600.26 kg/ha), Cynodon dactylon (346.74 kg/ha), Melaleuca leucadendron (255.21 kg/ha), and Melastoma malabatricum (156.40 kg/ha). While, the highest biomass in Tebing Penigasan plot is Cyperus rotundus (3575 kg/ha), and in Barak Gajah Plot is Isachne globusa (4013.33 kg/ha). The carrying capacity of elephants habitat of Tambang Besi, Tebing Penigasan, and Barak Gajah plots are 0.78, 0.29, and 0.41 individual/ha/day, respectively.

Abstract

Increased productivity of sugarcane in upland area can be done through the implementation of the integration of manure with a high dose of inorganic fertilizer in the double rows and twice plant populations of single row (“double rows double seeds”) planting arrangement. Limited availability of manure and inorganic fertilizer entails the replacement of manure with green manure fertilizer. The research was aimed to obtain a green manure as replacement manure that can be intercropped in the double rows double seeds planting arrangement. The experiment was done in the Asembagus Experimental Station, Situbondo, East Java on January to December 2014 for plant cane (PC) and from January to December 2015 for ratoon cane (RC). Treatments were arranged in a Randomized Block Design time for replication. The treatment includes (1) the four rows of Crotalaria juncea, (2) two rows of Crotalaria juncea, (3) four rows of peanuts in width between rows of sugar cane, (4) manure, and (5) no organic fertilizer. The results showed that the integration of organic fertilizer with a low dose of inorganic fertilizers increases productivity and sugar yield 5.20 to 41.78% and 33.33 to 69.90%, respectively in PC and 7.33 to 32.67% and 5.74 to 29.61%, respectively in RC from no organic fertilizer. Four rows of Crotalaria juncea could replace the role of manure in improving the productivity and sugar yield for PC and two rows of Crotalaria juncea for RC.

Abstract

Sheep is one of achievable animal protein sources. Therefore, they need to be transported to/in different places to fulfill the demand of mutton. This research was conducted to know the impact of transportation on stress as presented by leucocyte differentiation (N:L ratio). Blood were taken from sheep without stress transportation as a control for 12 hours.In this research, 12 sheep were divided into 3 groups: KP (control with stress),PA (stress with combination multivitamin and meniran - Phyllanthus niruri L.), PB (stress with combination multivitamin).Blood samples were taken at 0 hour (pre-transportation), 4h, 8h, 12h (during transportation) and 24h, 48h, 72h (post-transportation) to observe leucocyte differentiation. The results showed that ratio N:L (as stress indicator) were higher at all time periods during transportation and after the transportation. Sheep as a control group had reached the peak of ratio N:L at 0 h, meanwhile sheep with combination of multivitamin and meniran at 12 h and sheep with multivitamin only at 8. It means that the sheep with combination of multivitamin and meniran treatment was more effective to response the transportation stress.

Abstract

Data of Dipterocarpaceae species have been extracted from 8 studied plots of 1-ha each, distributed in three types of natural forest in Kalimantan (those were 4 plots in mixed dipterocarps forest, 2 plots in peat swamp forest and 2 plots in heath forest types) for further population analysis. Number of Dipterocarpaceae species in mixed dipterocarps forest type was higher than of in two other forest types, however mean number of individual per species was higher in peat swamp and heath forest types than of in mixed dipterocarps forest type. Some of Dipterocarpaceae species are adapted to heath and peat swamp forest type conditions indicated by the number and distribution of population of the species in both forest types. The higher the population number of juvenile trees 5-10 cm in diameter, the lower population number of mature trees of diameter 50cm up, indicated the higher tree population the higher mortality rate. However, survivorship of tree will higher as the tree diameter higher. Survivorship of trees in mixed dipterocarp forest is higher than of in peat swamp and heath forest types.

Abstract

A Vegetation study of some different freshwater swamp forests in Rimbo Panti Nature Reserve, West Sumatera was carried out with a quadrat methode.The results of a floristic inventory of trees with DBH e" 10 cm show that 136 species of 90 genera in 402 families ,presented by 1676 individuals, with the total basal area of 53.11 m occurred in the 5 hectare sample plots.The two leading families in terms of number of species were Euphorbiaceae and Lauraceae while according to the the total sum of importance values for families were Euphorbiaceae, Moraceae and Bignoniaceae.We recorded 19 species of Euphorbiaceae, constituting14.4% of the total species with the basal area of 39.4 % of the total in the three plots. Terminalia copelandii(Combretaceae) was the most prominent species occurring here and was one of the ten leading species. The species-area curves rose steadily up to an area of 1.0 hectare, with a very slight indication of levelling off at about 2 hectares, indicating high Heterogenity particulary in the permanently flooded swamp forest. Four largest trees were Artocarpus rotundatus (DBH = 100.50 cm) Chydenanthus excelsus (DBH = 92.50 cm), Haplophragma macrolobum (DBH = 83.00) and Anthocephalus chinensis (DBH= 75.10 cm).

Abstract

There are 525 native palm species to Indonesia.Chromosome numbers of 61 Indonesian palm species have been reported,unfortunately, not all species were presented by their karyotype. Re-observation of palm chromosomes is needed, because mis identification of particular species and uncorrect chromosome counts might be happen in the past. Chromosome characteristics of some families, such as Poaceae and Onagraceae were proved useful for classification.On palms, almost all species within similar genera were known had similar chromosome numbers and different in chromosome forms and sizes.Trends to employ chromosome characteristics for palm classification is possible.Since, chromosome information on palm is limited,chromosome research has great challenge to do in the future.
