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

Lampung, including the Register 31 Pematang Arahan area which is next to the Bukit Barisan Selatan National Park, is known for its high biodiversity, and its coffee production. Gapoktanhut Lestari Sejahtera, consisting of 13 Forest Farmer Groups (KTH), practiced community-based forest coffee under the KPH Kotaagung Utara, Tanggamus, Lampung. To support the development of biodiversity data base for KPH Kotaagung Utara, molecular-based species identification for robusta coffee has been carried out under BLU LPPM Unila grant year 2023 and in collaboration with the Lampung Disease Investigation Center. Robusta coffee leaf samples from six KTH areas (Bumi Mulyo, Sido Makmur 1, Sido Makmur 2, Sido Makmur 3, Mandiri Jaya, and Murah Rejeki) were collected for molecular species confirmation based on the N-methyl transferase genetic marker. Molecular analysis included DNA extraction, amplification, and electrophoresis conducted at the Lampung Disease Investigation Center. Sequencing was based on the Coffea canephora CAF2 genetic marker. Bioinformatics analysis was performed using the Basic Local Alignment Search Tool (BLAST) and Molecular Evolutionary Genetics Analysis (MEGA) software version 6. Identical sequence lengths of samples in 6 KTH are varied in base pair length and nitrogen base sequences, ranging from 163-530 bp, with 5 out of 6 KTH having a genetic distance of 0.000%, while 1 sample had a genetic distance of 0.006%. It indicates that robusta coffee samples from 6 KTH areas are genetically closely related.

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

Background. Bats (Chiroptera) are true flying mammals and nocturnal. Ecologically, bats play important roles as pollinators, seed dispersers, guano producers, biocontrol, and hosts a range of viruses. Cynopterus brachyotis belongs to fruit-eating bats and is considered morphologically cryptic with C. sphinx. Aims. To support morphological identification, molecular species confirmation needed to be conducted. DNA extraction, as an initial step, plays a crucial role in molecular analysis. Methods. The quality and quantity of extracted DNA determine the success rate of sequencing for species confirmation in bats. In this study, oropharyngeal samples were used. Result. The research procedures included bat capture and DNA oropharyngeal swab sample collection, sample preparation, DNA extraction using a silica column-based commercial kit, DNA concentration measurement using a Qubit assay, and electrophoresis. Conclusion. The Qubit assay showed DNA concentrations of >1 ng/µL, while electrophoresis did not reveal bright DNA bands.

Abstract

Background. The only flying mammals, bats, play an essential role in their natural habitat. Based on the type of food, bats can be divided into two groups: fruit-eating bats and insect-eating bats. Bats rank second-highest in species diversity, with 1,439 worldwide and 239 in Indonesia. Known as reservoirs of viruses, including coronaviruses. Aims. Bats are suspected to be related to COVID-19. Under the Research Innovation and Collaboration Program - Higher Education for Technology and Innovation Project (HETI) University of Lampung 2024-2025, and in collaboration with the Lampung Disease Investigation Centre, learning the procedures for handling bats properly so as not to physically harm bats in oral swab sampling and species recognition in Braja Harjosari, directly next to Way Kambas National Park was done. Methods. The life-trapping technique uses a mist net. Bat handling for taking oral swab was carried out using the pinch grip method, which is holding both arms of the bat backwards utilizing the thumb and middle finger with the bat positioned facing upwards. Conclusion. The bat's mouth is then blown open and a cotton swab is gently inserted into the bat's mouth. Afterwards, the bat is rested, given water drops, and released into nature. Oral swab samples from 10 individual bats: frugivorous bats, Cynopterus brachyotis (n = 8), Cynopterus horsfieldii (n = 1), and insectivorous bat, Scotophilus kuhlii (n = 1).
