The material used was sterile shoots Cloves 1 month of age as much as 9 buds, study design using a Completely Randomized Design with 3 treatments, using 5 ppm BAP + 0.5 ppm NAA, 6 ppm BAP + 0.5 ppm NAA, 7 ppm BAP + 0.5 ppm NAA. Each treatment was repeated 3 times sothere were 9 experimental units. Data were analyzed by ANOVA followed by Duncan's test. The results showed that treatment 6 ppm BAP + 0.5 ppm NAA showed a significant effect on the shoots and leaves of clove

Sistem Clustering Untuk Efisiensi Energi Pada Jaringan Sensor Nirkabel

Saat ini, penelitian tentang jaringan sensor nirkabel menerima banyak perhatian karena menawarkan keuntugan dari pemantauan berbagai macam linkungan dengan mendeteksi fenomena fisik. Jaringan sensor nirkabel terdiri atas sejumlah besar sensor node dimana setiap sensor node memiliki kemampuan untuk mengirim, menerima dan mendeteksi (melakukan proses sensor). Di sisi lain, sensor node memiliki kemampuan terbatas dalam hal kapasitas memori, bandwidth dan daya. Di antara berbagai isu, konsumsi energi menjadi perhatian banyak peneliti dikarenakan sensor node menggunakan baterei sebagai konsumsi dayanya. Pada penelitan ini dibandingkan kinerja protokol LEACH (distributed) dan LEACH-C (centralized), kedua protokol tersebut mendukung konsep clustering untuk menghemat daya baterei. Dari hasil pengujian, didapat bahwa unjuk kerja protokol LEACH-C lebih baik dari LEACH. Selain itu juga dilakukan pengujian dengan perangkat hardware yang sementara masih dilakukan proses kekuatan penyebaran daya dari sebuah sensor node hardware

Perception of Subject Matter Experts (SMEs) on various curation and preservation techniques for the development of natural history gallery in Malaysia: a qualitative study

Preserving animal’s body or part of the animals have become an important and wellknown conservation medium to ensure that the future generations are still able to enjoy the biodiversity and all the incredible species that live within it. This paper aims to present a qualitative study on perception and preference of subject matter experts (SMEs) on various curation and preservation methods that is suitable for certain animals for the development of Natural History Gallery. Interview with the SMEs were done by using semi-structured questionnaire and prior to this, permission were gained from the respondents by signing the Informed Consent Form (ICF). The findings suggest that the preservation methods of specimens ultimately depend on the purpose of specimens collected, either to be preserved as research specimens or exhibition specimens. The information gained form this study will be valuable as directive for the development of natural history gallery in Malaysia

A review on environmental DNA (eDNA) metabarcoding markers for wildlife monitoring research

Environmental DNA or eDNA utilizes traceable genetic materials in the environment for monitoring the presence of organisms in a given area and it is now gaining popularity as an alternative for traditional monitoring methods. Thus, the selection of genetic markers is crucial for identification of species in wildlife monitoring. This paper aims to review several DNA markers which are appropriate and reliable for detection of organisms from the environmental samples. We performed systematic literature search from SCOPUS database to review all molecular markers of eDNA. This study focuses on the importance of markers selection which can be utilized by next-generation sequencing (NGS) for biodiversity monitoring. Cytochrome C oxidase Subunit I (COI) are noted as the most widely used marker in metabarcoding research for detection of targeted species

Thermopower in the strongly overdoped region of single-layer Bi2Sr2CuO6+d superconductor

The evolution of the thermoelectric power S(T) with doping, p, of single-layer Bi2Sr2CuO6+d ceramics in the strongly overdoped region is studied in detail. Analysis in term of drag and diffusion contributions indicates a departure of the diffusion from the T-linear metallic behavior. This effect is increased in the strongly overdoped range (p~0.2-0.28) and should reflect the proximity of some topological change.Comment: 4 pages, 4 figure

Detection of HBV-DNA and Its Correlation with the HBeAg/Anti-HBe Serological Status in HBsAg-positive Patients

Background: In the past years, HBeAg and anti-HBe status in individuals with positive HBsAg were often correlated to viral replication. This study was aimed to find correlation between the HBV viremia and HBeAg/anti-HBe serological status in HBsAg-positive individuals. Method: An observational-analytic design was performed in this study. The sera of all positive HBsAg patients at Biomedika Hospital Laboratory were collected and examined for HBeAg and anti-HBe using immunochromatography technique between January and April 2012. The sampling method was purposive sampling. Afterwards, the sera were examined for HBV-DNA by polymerase chain reaction (PCR). Results: Sufficient amount of sera were collected from 44 patients consisting of 33 males and 11 females. The mean age was 15-68 years. Positive HBeAg and negative anti-HBe status was found in 11 (42%) patients. Negative HBeAg and positive anti-HBe was found in 26 (59.1%) patients. Both HBeAg and anti-HBe were negative in 7 (16.3%) patients. HBV-DNA was detected in all 11 (100%) patients with positive HBeAg and negative anti-HBe. HBV-DNA was also detected in 11 (42%) patients with negative HBeAg and positive anti-HBe. However, there was only one patient (14.3%) with both negative HBeAg and anti-HBe status, who had detectable HBV-DNA. Conclusion: Positive HBeAg can be used as an indicator of viremia, but negative HBeAg cannot be used as an indicator of the absence of viremia without further HBV-DNA testing. Patients with negative HBeAg and positive HBV-DNA were suspected for having pre-core mutant
