Abstract

Ecological study with special attention to vegetation analysis has been done in the Bintan forest area, Riau Archipelago. Based on three sampling plots of 30 × 30 m, there were 73 tree (dbh ≥ 5 cm) species were recorded, belong to 64 genera and 32 families. The density is fairly high (1,485 individuals /ha) with total basal area relatively low (27.71 m2/ha).  Its indicates that most of trees are small size. Similarity index among study sites are relatively low (< 25 %), indicates that there is strong relation between habitat and species composition. Out of the 6 most common tree species in the study area, only Dipterocarpus gracillis was dominant in 2 study sites. Overall species diversity is relatively low, which is characteristic of forest vegetation on small islands.

Abstract

This study was performed to evaluate the development of somatic embryo from embryogenic calli of ginger meristem culture. Completely randomized design was applied, replicated 4 times. Embryogenic calli from meristem tissue of inner shoot bud of rhizome obtained on MS medium containing 100 mg/L glutamine, 2% sucrose with the addition of 1.0 mg/L 2,4-D and 3.0 mg/L BA, were subjected to proliferation medium, MS and N basal media containing 3% mannitol. Then, transferred into somatic embryo maturation medium, either MS or N basal media supplemented with 6% sucrose. The number of somatic embryos-formed significantly affected by the proliferation medium applied. The highest number of somatic embryos (about 82.0 per 1 g friable calli) was achieved on the MS medium, 4 weeks after incubation. In addition, the optimum growth of embryogenic calli containing somatic embryos was obtained on MS and N medium supplemented with 6% sucrose. There were significantly difference between the media applied (MS and N ) to somatic embryos maturation. The highest number of mature somatic embryos (57.2 embrios) was achieved on the MS medium, 18 days after incubation.

Abstract

Study on the comparison between allantoin (5 ¢ ureidohydantoin) and Betadine ® (povidone iodine) was conducted to compare and evaluate their efficacy, especially to accelerate wound (incision) healing. Treatment divided into three groups, first group is Control (without therapy), second group is allantoin treatment and the last one is Betadine ® treatment. Allantoin obtained from cattle's urine by Meissner method. The solution made of 2,4 grams of allantoin in 600 milliliters aqueous solution. Treatments (therapies) were given three times a day topically. Results showed no significant difference between allantoin and Betadine ® treatments (p > 0,05), control and the other treatments i.e allantoin and Betadine ® therapies have significantly difference (p < 0,01).

Abstract

This study was to identify the pathogenicity of local isolates of Salmonella enterica serotipe enteritidis (S. enteritidis/SE) in experimental chickens and mice. Thirty six local isolates of S. enteritidis isolated from chickens, eggs and human was inoculated 8 intra peritoneally (ip) to each 5 chickens and mice per group. Each group received 0.2 ml of broth culture containing 2 x 10Â CFU of S. enteritidis. Chickens and mice were observed daily at 1, 2, 3, 4, 5, 6 and 7 days after inoculation for clinical signs and mortality. The result showed that the overall mortality rate of chicken and mice were 78.4% and 63.9% respectively. The highest mortality rate was in the first day after inoculation, 51.1% for chickens and 40.0% for mice, however the lowest mortality rate was in the sixth day (0.0%) after inoculation in chickens and in the seventh day (0.6%) in mice. The bacteria of S. enteritidis can be isolated from various organs (liver, heart and spleen) and caeca tonsil of every dead chickens and mice. The study showed that local isolates of S. enteritidis isolated from chickens, eggs, and human were very pathogen for experimental chickens and mice.

Abstract

Buah salak sudah cukup dikenal, walaupun jarang sekali orang menempatkannyapadaurutan tertinggi di antara kumpulan buah-buahan yang enak dimakan. Tetapi ini bukan berarti salak tidak mempunyai nilai ekonomi sama sekali sebab di Jakarta, Bogor, Bandung, Yogya, Penpasar dan di Iain-lain kota harganya dapat mencapai Rp. 50,- per buah. Karenanya kebun-kebun salak yang terdapat a.l. di Condet (Jakarta), Manonjaya (Tasik), Sleman (Yogya), Bangkalan (Madura), Kaiang Asem (Bali), Pangu serta Tahu Landang (Sulawesi Utara) dapat memberikan penghasilan yang cukup berarti bagi para pemiliknya. Di Manonjaya misalnya, dari 300 rum pun pohon salak dapat dihasilkan rata-rata 6000 buah setiap bulannya. Di desa tersebut terdapat kebun-kebun rakyat yang keseluruhannya berjumlah hampir 400 ribu Ha dan memiliki hampir 3 juta pohon salak. Karena itu tidaklah mengherankan jika produksi buah salak di sana ternyata mempunyai peranan besar dalam pembangunan desa, seperti perbaikan jalan desa, pembangunan gedung sekolah dan Iain-lain.

Abstract

In order to know the capability of lignin and cellulose degradation and phosphate solubilization by soil fungi of Gunung Halimun National Park, a study was carried out to qualitatively analyse its physiological properties. Out of 35 soil fungi tested, 1 species that belonged to Basidiomycetes degraded lignin, 32 species degraded cellulose, and 31 species dissolved inorganic phosphate.The presence of soil fungi that degraded cellulose and dissolved phosphate could be used as a candidate for biotechnology application as well as to increase soil fertility.

Abstract

Study on production potential of adventitious root of the scaly tree fern Cyathea contaminans was conducted in six locations in West Java and North Sumatra using 20 m x 50 m sampling plot. Data recorded in the study consisted of population density, individual heights and diameter, volume of adventitious roots and environmental factors. The highest population density was found in a population that consisted of saplings with the height of less than 2 m tall. While population with adult plants has the density of 26–36 individual/100 m2. The wighest average volume of adventitious root per individuals was found in a population that dominated by adult stands and lies on a gentle slope at 108,760.70 cm3/individuals, while the lowest was in a population that consisted of saplings. The result statistical analysis showed that production of adventitious root were significantly different in different habitat. Moreover, there was positive correlation between trunk diameter and individual height with the volume of adventitious root, and between the diameter with individual height.

Abstract

High aluminum (Al) toxicity and soil acidity are the most important problems that cause low soybean productivity on actual acid sulphate soil. Soil quality improvement by using ameliorant and introducing adaptable variety are some options to increase soybean productivity in the soils. Field experiment was conducted to evaluate effect of using ameliorant and variety of soybean to increase its productivity onan actual acid sulphate soil of Simpang Jaya, Wanaraya, Barito Kuala District of South Kalimantan, during dry season of 2009. The research was arranged in a split-plot design with three replicates. The main plots were three soybean varieties, i.e. Lawit, Anjasmoro, and Argo-mulyo, while sub plots were five levels of lime i.e. K100, K80, K60, K40,K20.Result showed that liming improved soil quality and soybean yield. It significantly increased soil pH and reduced soil Al saturation. The liming also increased plant growth and yield variables (plant height, dry matter, root weight and yield) at three tested varieties. Anjasmoro was more adaptive than the others varietyon actual acid sul-phate soil.

Abstract

Keladi tikus Thyponium flageliforme (Lodd.) Bl. is considered as a wild plant species, because it is not fully cultivated yet. However,now adays it is quite widely used even in its wild status, because it is reported to be traditionally used as cancer cure. Due to its potential uses by the people, there is a need to be developed by cultivation in order to fulfill the demand for raw materials, both for medication and planting materials in research activities. This research was conducted to study the behaviour of keladi tikus when bring to cultivation status. The research is divided into two parts i.e: a) the effect of bulb weight as planting material and 2) the effect of shading on the growth. The result sshowed that bulb weight is not significantly affected the growth. On the 10'month after planting the parameter measured is not significantly different. Meanwhile, shading is significantly affected the plant growth. The best growth is achieved on 0% shading, but the growth on 50% shading is still good. The growth on 75% shading has significant decreased.
