Abstract

The restoration effort in Tamban Beach may reflect the role services of mangroves as suitable habitats for those surrounding diversity, especially on avifauna. Here we assess the diversity and community of avifaunal throughout types of mangrove ecosystems. We surveyed the avifaunal within four stations (i.e., natural mangrove area, restored mangrove area since 2009 and 2014, and degraded mangrove area) in Tamban Beach, Sumbermanjing Wetan, East Java during March 2021 using Audiovisual Encounter Survey (AES) methods. We present the statistic descriptive analysis of α-diversity index (taxa diversity, dominance index, Simpson’s index, Evenness, Shannon-Wiener diversity index, Brillouin index, and Margalef species richness) as diversity assessment also conservation status of each species. The Principal Component Analysis (PCA) was performed to investigate the community variation within each site. We found 38 species from 22 families and 11 orders of avifaunal across the sites. The diversity of avifauna was high in a degraded area due to the mixture of habitats, although the natural and restored area yields some specialists. The type of mangroves might not be the sole factor affecting the avifauna diversity correlation, highlighting the importance of conservation strategies in the area.

Abstract

Barramundi fish is one of the most important aquaculture commodities, with cultivation challenges closely related to its survival and growth. There is still a lack of information on digestive enzymatic activity profiles and larval growth, and the use of Australian brooders rather than Indonesian brooders is still frequent. This study aims to investigate digestive enzymatic activity profiles and their correlation to the growth performance of barramundi larvae, Lates calcarifer (Bloch, 1790), originating from Indonesia and Australia. The digestive enzyme activity profile was evaluated using real-time quantitative polymerase chain reaction (RT-qPCR). First, larvae were reared in captivity till day 20 (20 dah). During this rearing, measurements of length and weight growth were done every day. Experiment data shows Australian fish larvae were greater than that of the Indonesian. Their digestive enzyme activity also confirmed that Australian larvae had more activity than Indonesian larvae.

Abstract

Studies reported that kenitu (Chrysophyllum cainito) has the potential as an anti-obesity agent. However, the mechanism underlying that activity remains unknown. On the other hand, targeting PPAR-y has played a beneficial role in regulating obesity. Therefore, this study will explain the anti-obesity potential of natural compounds from C. cainito in modulating obesity through inhibition of PPAR-y. Molecular docking was employed to identify the possibility of several compounds binding with the PPAR-y. Moreover, the stability of the interaction between PPAR-y and each compound was also evaluated using molecular dynamics analysis. The result showed that beta-sitosterol, lupeol, myricitrin, quercitrin, rutin, vitamin A, epicatechin, and chlorogenic acid are worthy of potential as PPAR-y antagonists. In advance, molecular dynamics simulations revealed that chlorogenic acid, quercitrin, and epicatechin were the most stable compounds to interact as an inhibitor of PPAR-y. In conclusion, compounds from star apple have some potential to improve the health status of patients’ obesity through PPAR-y antagonist activity.

Abstract

In Bromo Tengger Semeru National Park (BTSNP), buffer zone areas, one of which is the Lesti upstream rivers, play a critical role in sustaining biodiversity and community life. Frogs serve as a bioindicator of environmental change, particularly in the upstream rivers of the Lesti. The present study examines the diversity and community structure of Anura in the upstream rivers of Lesti, which are included in the BTSNP buffer zones. Throughout the surveys, up to 14 anuran species were encountered in four sites adjacent to the BTSNP border and crossed by the Lesti rivers. This study suggests that buffer zones may support herpetofaunal diversity by allowing humans to interact with them and sustainably utilize the resources in the areas. Urban development and conservation in these areas must be kept current in order to minimize environmental disruption caused by humans.

Abstract

The antivenom for Malayan krait (Bungarus candidus) venom has not yet been available in Indonesia, leading to many fatal snakebite cases. Alternative treatment approaches using medicinal plants are needed to be explored. This study investigated the potential of medicinal plants’ natural bioactive compounds as toxic alpha-delta bungarotoxin protein inhibitors in B. candidus venom. The approach taken is using the 3D structure of the alpha-delta protein of bungarotoxin B. candidus predicted by SWISS-MODEL. Knapsack Family Database and PubChem were used for bioactive compounds datamining. ADME analysis and drug-likeness of the compounds were carried out with SWISS-ADME. Docking between alpha-delta-Bungarotoxin protein and bioactive compounds was carried out with Pyrx 0.9.5. Visualization of docking results was performed with PyMOL and Discovery Studio 2016 was used to evaluate docking interactions. The docking results showed that a compound with the potential inhibitor of alpha-delta bungarotoxin came from Ashwagandha (Withania somnifera) with a binding energy ranging from -6.6 to -6.9. The compound with the best inhibitor potential, namely withanolide D, was seen from the stability of the interaction based on hydrogen bonding at three amino acid residues: THR59, SER62, and THR63. The evaluation is supported by the results of molecular dynamics simulations which show stability in almost all aspects. Our results suggest the potential for exploratory research in the field of bioinformatics related to bioactive compounds from herbal plants as an alternative to antivenom.
