Abstract

Hot water temperature can be a place for the development of thermophilic bacteria. Thermophilic bacteria produce thermostable enzymes which are needed in various industrial fields such as agriculture, food, detergent, pharmacology, and bioremediation agents. This study aims to isolate and characterize potential proteolytic and amylolytic bacteria from the Bayanan hot spring. Samples were collected from two distinct locations within the geothermal environment: the hot spring source itself and the associated water storage pools. The collected samples underwent a dilution and isolation process to obtain pure bacterial cultures. Subsequently, these isolates were inoculated onto selective media, including skim milk agar (SMA) and nutrient agar (NA), to assess their proteolytic and amylolytic activities, respectively. The presence and extent of these enzymatic activities were determined by measuring the diameter of the clear zone surrounding each bacterial colony. The analysis revealed the presence of eight proteolytic bacterial isolates and twenty amylolytic isolates. Notably, a hydrolysis index threshold of ≥2.5 was implemented to identify isolates with high potential for proteolytic and amylolytic activity. Based on this criterion, two proteolytic bacterial isolates (codes B2-12-C3 and B1-12-B3) exhibited a proteolytic index exceeding 2.5. Furthermore, eight amylolytic isolates displayed an index above 2.5 (codes B1-10-A1, B1-10-A3, B2-8-A1, B2-8-A2, B2-10-A1, B2-10-A2, B2-12-C1, and B2-12-C2). These isolates, particularly those with high hydrolysis index values, has potential as bioremediation agents due to their demonstrated ability to efficiently hydrolyze proteins and starches.

Abstract

The high diversity of tree species found in natural forests contributes to their ability to maintain ecological balance. Mount Baung Natural Tourism Park is the conservation area in Pasuruan Regency, East Java that functions to protect biodiversity. The research aims to identify tree species, analyze tree diversity, and determine tree dominance with the importance value index (IVI). The research was conducted from February to March 2023 in Mount Baung Natural Tourism Park utilization block (MBNTP UB), Pasuruan Regency, East Java, Indonesia. The observation location was determined to be 37 points and plots were made in the point with a size of 20 m × 20 m for the tree phase, 10 m × 10 m for pole phase, 5 m × 5 m for the sapling phase, and 2 m × 2 m for the seedling phase. Data collected from field observations were analyzed to determine the Shannon diversity index using PAST 4.01. Tree dominance was analyzed using IVI. The research showed that 14 species from 8 tree families are found in MBNTP UB. The Fabaceae family is found to be abundant compared to other families. The highest number of individuals found in the seedling phase is Cassia glauca. Swietenia macrophylla has the highest individual’s number in the sapling, pole, and tree phases. The highest tree diversity is found in the tree phase. Diversity at the tree phase is classified as moderate, while at the seedling, pole, and sapling phase the diversity is low.

Abstract

Approximately 80% of flowering plants are highly dependent on insect pollination, including the chili pepper (Capsicum frutescens). Environmental conditions serve as parameters for insects in their activities. Therefore, this study was conducted to determine the diversity and abundance of flower-visiting insects in C. frutescens and their environmental factors. Field observations of flower-visiting insects were conducted during the dry season utilizing aerial capture methods. The data was analyzed using diversity, abundance, evenness, and dominance indices equations. Multiple linear regression analysis was also conducted to determine the abiotic and biotic factors (environmental factors) that influence the abundance of flower-visiting insects. The analysis results showed that a moderate trend in the diversity of insect and as many as 33% of the total recorded insect individuals belong to the Vespidae family. The Allorhynchium argentatum showed the highest species abundance (27% individuals). Based on the multiple regression analysis results, environmental factors had a non-significant native influence on the abundance of flower-visiting insects. Environmental conditions during the dry season have a weak influence on insect interactions with plants.
