Abstract

Salah satu hambatan perkembangan penelitian ektoparasit ialah susahnya mengenal tingkat-tingkat pradewasa kebanyakan jenis-jenis parasit.Ini terutama disebabkan karena besarnya perbedaan morfologi, bentuk maupun ukuran, cara hidup serta habitat antara tingkat pradewasa dengan yang dewasa. Hal ini terasa makin perlu ditanggulangi apabila berhubungan dengan jenis-jenis penting dalam segi ekonomi ataupun kesehatan. Masalah pengenalan larva caplak suku Ixodidae sedikit banyak telah dapat dipecahkan setelah diperkenalkannya sistim penggunaan kaetotaksi oleh Clifford & Anastos (1960). Dengan sistim ini dimungkinkan untuk mengenal identitas larva meskipun sifatnya tidak menyeluruh hanya sampai tingkat marga saja.

Abstract

The aim of this study was to evaluate the genetic diversity of three populations of Snakeskin Gourami (Trichopodus pectoralis;Osphronemidae)from three provinces of Indonesian Borneo:West, Central, and South Kalimantan using Random Amplified Polymorphism DNA (RAPD) and morphometric truss methods.DNA amplification using primer OPC-02,OPC-05,and OPA-09 resulted in 21 to 28 fragments with sizes ranged from 200 to 1600 bp, polymorphism value was of 7.14 to 25.00%, heterozygosity was of 0.02 to 0.11 and the genetic distance between populations was of 0.27 to 0.28.Truss morphometrics analysis showed that the coefficient of variability was ranging between 2.75 to 12.52%.There were 9 characters that can be used as diagnostic characters for Snakeskin Gourami. The intra population similarity index in Snakeskin Gourami populations from West Kalimantan was the highest (80%) followed by populations from Central Kalimantan (16.7%) and South Kalimantan (3.3%).The results of RAPD and truss morphometric analysis suggested that populations from West Kalimantan have higher genetic diversity than populations from Central and South Kalimantan.

Abstract

The experiment was carried out in the Laboratory of Rice Research Institute Bogor, on October 1996 to February 1997. The aim of the experiment was to study the survival rate and nymphal stages of these cobnies on a set group of rice varieties with different gen of resistance agains tungro disease. How far the source of resistance gen has been broken after the varieties have been planted by farmers alter several years. The source of colonies were taken from Bali, Central Java, West Java and South Sulawesi. Observation has been taken for the survival rate and the nymph period of each colony on each of varieties tested i. e. TO-Cisadane; T1-IR26; T2- Ciliwung; T3-IR 64 and T4-IR 72. The Completed Randomised Design was used to analyze the results. The results indicated that IR 72 still show resistance to N. virescens Bali colony and Centra! Java as shown from the longer of nymph periods compared to Cisadane as control variety. The survival rate was also still tow (21,66%), while on susceptible variety Cisadane reached around 66,66%. However, from West Java and South Sulawesi colonies, IR 72, no significant different has been found with Cisadane. IR26 and Ciliwung found to be resistant against colony of South Sulawesi as indicated from the low of survival rate i.e 10% and 28,33% respectively. IR 64 has been adapted for all colonies tested as shown from the higher of survival rate and the shorter of nymph's periods.

Abstract

Previous ecological studies have revealed the types of non-forest frog commonly occupying habitats that have been modified by humans are still severely limited. For that purpose the research was conducted in the wetland area of Ecology Park in LIPI Campus Cibinong which is located at S 06" 29' 40.2"; E 106° 51' 06.3" with 165 meters altitude above sea level (asl) over seven months (May-November 2009) by monitoring 14 times during the study period (July-November).The transect method was used to determine the effect of habitat on the diversity and abundance of frog species in the wetland area. Transect was set for 100 meters on one side of the lake where the area has a variety of habitat types. Length of 100 meters transect was divided into 10 sections with 10 meters length for each section, (length of each section was 10 meters). Every 10 meters, the type of habitat, frog species encountered and the abundance of the species were recorded. Environmental data recorded were air humidity, air temperature, water temperature and moon phase (full moon, crescent moon or the dark moon). Ten frog species which belong to 4 families, the Bufonidae (Bufo biporcatus and B. melanostictus), Microhylidae (Kaloula baleata), Ranidae (Fejervarya cancrivora, F. limnocharis, Rana chalconota, R. erythraea, R. nicobariensis and Occidozyga lima) and Rhacophoridae (Polypedates leucomystax) were found.R. erythraea, R. nicobariensis and O. lima were the dominant species and found on every visit. Furthermore, the most dominant species was R. erythraea. The results showed that environmental factors (air temperature, water temperature, humidity and conditions of the moon) did not have an impact on the presence and number of species. Abundance of three dominant species (R.erythraea, R. nicobariensis and O. lima) was strongly linked to vegetation type. Moreover, environmental factors (water temperature, humidity and the condition of moon) affected the abundance of R. nicobariensis in sub transect 2 and 5 where dominated by Eleocharis dutcis ans Leerxia hexandra. On the other hand air temperature affected the abundance of O.lima in sub transect 7, dominated by floating lotus plant Nymphaea lotus.

Abstract

The objective of the experiment was to investigate the effect of rice straw application on the growth of rice in two conditions of acid sulphate soils. An experiment was conducted in the glass house consisting of three treatment factors using the completely randomized design with three replications.The first factor was soil condition consisting of continuous application of rice straw and without application of rice straw during the last 5 years. The second factor was fresh application of rice straw consisting of application and without application, whereas the third factor was P application consisting of 3 rates of SP - 36 fertilizers.Parameters measured were plant height, tiller number and Fe toxicity score. Measurement were conducted at 2, 4, 6 and 8 weeks after planting. Plant dry weight and P concentration in plant tissue were determined at 8 weeks after planting. The result showed the main effect of rice straw application was significant decrease on the tiller number of the rice plant at 2, 4 and 6 weeks after planting, whereas significant on plant height was observed at 2 and 4 weeks after planting. Based on the scoring of degree of Fe toxicity, it was concluded that the rice plant did not exhibit any effect of Fe toxicity.

Abstract

Alang-alang (Imperata cylindrica (L.) Beauv.) has been widely used as a medicinal plant to treat some diseases, such as fever, headache, and diuretic. Nowadays, there is no information of genetic diversity of this plant used in herbal formula by ethnic groups in Indonesia. The main objective of this study was to asses genetic diversity of alang-alang from 18 selected ethnic groups in Indonesia based on Inter Simple Sequence Repeats (ISSR). Location of sample collection was identified by using data on Research on Medicinal Plant (Ristoja) 2012. Total DNA genome was isolated and ISSR primer screening were done on collected samples. Ten selected ISSR primers produced 74 amplified DNA fragments 58, fragments (78.4 %) were polymorphic. Dice index similarity was used to construct UPGMA dendrogram. The genetic similarity indexing which among accessions was ranged from 70.5–90.5% thereby indicating a low level of genetic diversity occurred in alang-alang. The results of this study also showed that ISSR markers were able to genetically differentiate alang-alang accessions by which this information can be useful for further researchs such as for standardization of medicinal plants.
