Abstract

The purpose of this study was to determine the utilization and cultivation of myrmecophytes as medicine by the community in Bengkulu Province. The sampling of this research was conducted through interviews with 5 key informants and 50 respondents using purposive sampling method and direct observation in the field, literature study and documentation. The results of the interviews were then analyzed descriptively to determine the utilization and cultivation of myrmecophytes as medicine by the community in Bengkulu Province. The results showed that there are two species of myrmecophytes namely Hydnophytum formicarum and Myrmecodia tuberosa in Bengkulu Province. These myrmecophytes is utilized by the people of Serawai, Rejang, and Lembak tribes for various types of diseases such as headaches, diabetes, tumors, aches, joint pain, cancer, rheumatism, high blood pressure, jaundice, vaginal discharge, back pain, and hepatitis. The myrmecophytes is also commercialized by the community by chopping and drying. The community that uses myrmecophytes also cultivates the plant using traditional methods such as placing it in coconut fiber, giving it soil media, and hanging it on trees in the residents yards. Information about the ethnobotanical study of myrmecophytes is expected to be known by the community in Bengkulu Province at large so that this plant can be recognized as a medicinal plant and an alternative to traditional medicine.

Abstract

The objective of this study was to perform a comprehensive evaluation of the application of liquid smoke as a possible antibacterial agent. The studies were identified by conducting searches on multiple electronic databases, specifically Semantic Scholar, PubMed, and Google Scholar, from 2013 to 2024. The keywords used included ‘antibacterial of wood vinegar, antibacterial of pyroligneous extract, antibacterial of pyroligneous acid, antibacterial of wood distillate, antibacterial activity of liquid smoke, and aktivitas antibakteri asap cair (in Bahasa Indonesia)’. The results indicate that liquid smoke has the capacity to serve as a natural antibacterial agent against both Gram positive and Gram-negative microorganisms. The variation in antibacterial susceptibility may arise from the composition of chemical compounds present in liquid smoke, the raw materials employed in its production, the temperature of pyrolysis, and the specific testing methodology employed. This review will be useful to the industrial and scientific communities in the food science, pharmaceutical, and technology fields.

Abstract

The pr-1 gene is a gene that encodes the PR-1 (Pathogenesis-Related 1) protein which plays a role in the plant defense response to pathogen infection. Although the role of the pr-1 gene as a defense protein has been known, the specific mechanism of how pr-1 responds to various types of pathogens in various plants is still poorly studied in various studies. Therefore, an in-depth analysis is needed regarding the role of the pr-1 gene in plant resistance. This study aims to determine the role of pr-1 (Pathogenesis Associated Proteins-1) gene expression on plant resistance and its implications for agricultural biotechnology. The research method used is a literature study with a qualitative approach. The results of the literature findings were then analyzed descriptively to determine the role of the pr-1 gene in the plant defense response. The findings show that the main role of the pr-1 gene is as a plant defense system against biotic and abiotic environmental threats. The plant resistance mechanism carried out by the PR-1 Protein will be active if there is PAMP/MAMP detection received by the plant cell surface receptor PRR (Pattern Recognition Receptors) to carry out the function of gene expression in plant organs.

Abstract

North Morowali Regency is one of the regions in Central Sulawesi Province that has prospects for developing seaweed aquaculture activities. The study aims to analyze the technical and financial feasibility of seaweed cultivation in Petasia Timur District. The data collection method is carried out by observation and interviews covering the technical and financial aspects of seaweed cultivation. North Morowali Regency has a fairly large cultivation location, especially in East Petasia District. However, in recent years there has been  a decrease in production due to problems with the quality of sea water. This study aims to analyze the technical feasibility of seaweed cultivation. The results showed that the water quality parameter data obtained from 3 sampling villages in East Petasia Timur District, namely Ungkea Village with a score of 53,3%, Bungintimbe Village 55,5%, and Towara Pantai Village 53,3%. In general, the value is below the range of water feasibility, so that the cultivation sites in the three sampling villages are said to be less suitable for seaweed growth.

Abstract

Epiphytic ferns (Pteridophyta) are vital components of tropical forest ecosystems due to their role in maintaining microclimate humidity, supporting nutrient cycles, and providing habitat for small fauna. This study aims to identify epiphytic fern species and analyze their morphological adaptations and spatial distribution patterns in Bukit Cogong, a part of the Kerinci Seblat National Park (TNKS). The research employed a descriptive-explorative method using both quantitative and qualitative approaches. Six purposively selected plots measuring 20×20 meters were established across various microhabitat conditions. Data were collected through species inventory, morphological observations, and measurement of environmental parameters. Results revealed seven species of epiphytic ferns, including Pyrrosia piloselloides, Asplenium nidus, and Davallia trichomanoides. The Shannon-Wiener diversity index ranged from 1.67 to 1.86, indicating moderate to high diversity levels. Each species exhibited distinct morphological adaptations to the epiphytic lifestyle, such as frond shape, rhizome structure, and trichome presence. Species tended to exhibit a clustered spatial distribution, influenced by microclimatic heterogeneity and host tree characteristics. These findings contribute to the understanding of adaptive strategies in epiphytic ferns and support conservation efforts for species and habitats within TNKS.

Abstract

Petroleum is a non-renewable natural resource that continues to be used in many applications. However, the availability of crude oil ready for use is decreasing due to the low productivity of oil wells, one of which is caused by its high viscosity. This needs to be resolved to meet the demand for crude oil. This study aims to determine the potential of eight petrophilic bacteria in producing biosurfactants and to determine their interaction to be applied to Microbial Enhanced Oil Recovery technology. The research design in this study was a Factorial Randomized Group Design with two types of treatments: 8 types of bacteria and 4 different temperatures. The experimental units were 32, with 2 replications of each, resulting in 64 experimental units.  The observation variables in this study were the diameter of the clear zone and the interaction of bacteria. Clear zone diameter was analyzed using Analysis of Variance, then continued with Duncan's New Multiple Range Test at 5%. This study showed the formation of clear zones as an indicator of the production of biosurfactants influenced by temperature. Brevundimonas   diminuta and P. peli have superior potential in forming clear zones in hemolytic assay than other bacteria, with clear zone diameters of 26.805 mm and 26.040 mm, respectively, at 44°C of incubation. Three bacteria have a high percentage of synergy in this study of 50%, which synergized with 4 other types of bacteria.

Abstract

This study aims to examine the dominance of Synedra ulna as a bioindicator in assessing the water quality of the Kedurang Sub-watershed (Sub-DAS) located within the Forest and Land Rehabilitation (RHL) area of Batu Ampar Village, South Bengkulu. A quantitative and qualitative approach was used by measuring physicochemical parameters (temperature, pH, TDS, and DO) and analyzing the phytoplankton community structure, with a focus on the Bacillariophyceae class. Samples were collected purposively from two stations with different ecological conditions. The results showed that Synedra ulna was highly dominant, with dominance index values of 0.75 and 0.92 at Stations 1 and 2, respectively. The water's physicochemical conditions were within the optimal range for phytoplankton growth, with temperatures of 24.9–29.8°C, pH of 7.5–8.0, TDS of 103–125 ppm, and DO of 7.9–8.2 ppm. The high dominance of S. ulna indicates moderate ecological pressure due to anthropogenic activities and suggests that the aquatic ecosystem is in a recovery phase. These findings highlight the potential of Synedra ulna as an effective ecological indicator for monitoring the success of forest and land rehabilitation efforts
