Abstract

Stingless bees are one of the honey-producing groups that are currently in increasing demand. The significant rise in honey demand necessitates research into the variety of stingless bee species that have the potential to produce high-quality honey in large quantities. This study aims to determine the genetic relationship of stingless bees from two colonies in Rajabasa, Bandar Lampung. Samples were collected from two different colonies in Rajabasa, Bandar Lampung. Molecular analysis was conducted, including DNA extraction, amplification, DNA sequencing, and phylogenetic analysis using the 16S rRNA gene. The study assessed homology values, genetic distance, and the phylogenetic map. The results indicated that the individual samples, GB1 and GB2, found in Bandar Lampung, were closely related to the species Heterotrigona itama. This was confirmed by the query value of both samples being 100%, with similarity values of 96.99% and 97.20%, respectively. The genetic distance analysis, visualized in the phylogenetic map, also shows that the two samples are close relatives of Heterotrigona itama.ABSTRAK: Lebah tanpa sengat menjadi salah satu kelompok penghasil madu yang saat ini makin banyak diminati masyarakat.

Abstract

Pesawaran is one of the areas that has the potential to cultivate stingless bees as producers of honey and propolis. This study was aimed at qualitatively analysing partial amplicons of the 16S rRNA gene from individuals found at the research site. The research was performed from April to September 2023 in an explorative approach. Based on the exploration that has been done in Harapan Jaya Village, Way Ratai District, Pesawaran Regency, individual stingless bees were obtained from 5 different colonies. Individual samples of stingless bees were further extracted and amplified by commercial kits. Each individual from 5 different colonies has successfully obtained its DNA amplicons. Based on qualitative analysis using 1% agarose gel, the size of the partial gene ranged from 400bp to 500bp. This result is in accordance with the data contained in the genbank, where the 16S rRNA gene size is more than 500bp. Therefore, it has been concluded that the size of the partial amplicons of the 16S rRNA gene of individual stingless bees from the 5 colonies that were obtained is actually in range of the size of the 16S rRNA gene of stingless bees that have been recorded in the genbank.

Abstract

Background. Identifying bat species based on morphological characteristics often faces challenges due to character overlap among species, especially within cryptic species groups. Cynopterus brachyotis is one of the fruit bats with high genetic diversity but relatively uniform morphology. Aims. Therefore, a molecular approach is needed to support accurate species confirmation. Under the HETI Research Grant of Innovation and Collaboration Batch 3- II Year 2025, this study aims to obtain genomic DNA from C. brachyotis bats caught at the Lampung Disease Investigation Center as the initial step of molecular species confirmation. Methods. Samples were obtained by taking oral swabs on bat individuals caught using mist nets. DNA extraction is performed using silica membrane-based methods with commercial kits. Quantitative evaluation of DNA was performed using a Qubit Fluorometer, while qualitative evaluation was performed by agarose gel electrophoresis. Conclusion. The results showed that the DNA concentration was in the low range (0.1–0.7 ng/μL), with a DNA band appearing very thin on electrophoresis. Implementation. Nevertheless, the quantification results confirm that DNA was successfully extracted and remains suitable for advanced molecular analysis, with optimization at the DNA amplification stage.

Abstract

The development of non-invasive methods is essential for monitoring critically endangered species such as the Dicerorhinus sumatrensis. This study aimed to evaluate the potential of tree bark associated with rubbing behavior as a source of environmental DNA (eDNA) for species detection in Way Kambas National Park. A total of 30 samples were collected from tree bark surfaces showing evidence of rubbing activity. DNA was extracted and analyzed using two approaches: simple electrophoresis and polymerase chain reaction (PCR)-based molecular methods. The results showed that the simple method failed to detect visible DNA bands, indicating low DNA concentration and degradation in environmental samples. In contrast, PCR amplification successfully detected DNA in 5 out of 30 samples, including hair-derived and epithelial residues associated with rubbing behavior.containing hair residues produced more reliable detection compared to those with only epithelial traces. These findings demonstrate that tree bark able to serve as a potential non-invasive source of eDNA, particularly when analyzed using sensitive molecular techniques. This approach provides an alternative method for detecting elusive species and contributes to the development of effective conservation strategies for the sumatran rhinoceros.
