Abstract

Tooth extraction is one of the simple procedures commonly found in dentistry. Bleeding is a common complication following this procedure. It requires special equipment and can quickly lead to shock, syncope, and death if not treated promptly. This study aimed to determine the effectiveness of Areca seed or beetle leaf ethanol extract in shortening bleeding time after tooth extraction in a Wistar rat model. Thirty-two male Wistar rats were divided into two treatment groups. The first group was treated with piper beetle leaf ethanol extract, and the second group was treated with areca seed ethanol extract. This extract was directly applied to the tooth socket. Meanwhile, the bleeding time was recorded on a filter paper every half minute using a stopwatch. All data were analyzed by T-Independent Test. The results of this study indicated a significant difference in bleeding time between the first group (betel leaf ethanol extract) and the second group (areca seed ethanol extract) with a p-value < 0.001. The mean bleeding time for the first group (143.19 ± 15.93 seconds) was longer than that for the second group (88.06 ± 23.80 seconds). Overall, it can be concluded that the areca seed ethanol extract significantly shortens bleeding time compared to piper beetle extract.

Abstract

Codiaeum variegatum (L.) Rumph. ex a. Juss is a common ornamental plant with a high variation of leaves shape and colour. This study aimed to analyze the leaves’ anatomy and the phenetic relationship between eight cultivars of C. variegatum which were defined by the differences in leaf morphology. The paraffin method prepared the transversal section of leaves, and anatomical characters were converted into binary data to calculate the similarity coefficient which was analyzed by Numerical Taxonomy System (NTSYS) 2.1 version. Leaves of eight cultivars of C. variegatum are varied in the anatomical structure of the primary vein and lamina. The eight cultivars of C. variegatum were clustered into four. The variations were found in 19 primary vein and lamina anatomy characteristics and the similarity coefficient is up to 0.59 between all cultivars. It can be concluded that the combination of leaf anatomical structures and midrib anatomical characters have notable taxonomic implications for future research.

Abstract

The purpose of this study was to characterize the active compounds in Indonesian local rice that are resistant to environmental stress in order to identify the nature of resistance to environmental stress, one of the indicators of which is the presence of flavonoid compounds. This step is one of the efforts that will lead to the acquisition of gene donors in the assembly of varieties resistant to biotic stress (pests and diseases) and abiotic stress (drought, high salinity, low temperature), which are very necessary in rice breeding programs. The method used is to plant 8 local rice varieties that are resistant to environmental stress in buckets in greenhouses. Next, analyze the content of active compounds by extracting the leaves and stems of rice plants, then macerate with methanol for 48 hours and test the content of active compounds. Then the total flavonoid content test was carried out using a quercetin standard and measured using a spectrophotometer. Whatever the results of this study, all samples showed active compounds containing flavonoids, alkaloids, tannins and saponins which were indicated by indicators of color change when tested with certain reagents. The results of the Flavonoid content analysis showed that the pendok variety had the highest flavonoid content, namely 3.9253 ± 0.06, and the Sigupai variety had the lowest flavonoid content, with a value of 1.8073 ± 0.07.

Abstract

Sei Nagalawan Village in Serdang Bedagai Regency, Indonesia, utilizes the mangrove ecosystem for economic benefits through creative activities and fishing. However, long-term use raises ecological and social problems, requiring a balance between conservation and development. This post-positivism-based study explores the transformation of Sei Nagalawan into an ecotourism center, involving stakeholders such as local government, ecotourism managers and the media. Drone mapping reveals a variety of attractions at Mangrove Beach, but challenges such as marketing, infrastructure problems and limited shrimp cultivation skills hinder community empowerment. This program, led by the Muara Baimbai Mangrove Conservation Group, aims to increase capabilities, improve economic prosperity and environmental awareness. Identified weaknesses indicate low awareness and support. Opportunities arise from tourist interests, but threats arise from waste problems and conflicts of interest. The strategy includes mangrove management, conservation, online promotion and education, aiming to achieve a balance between conservation and economic activities, while recognizing existing challenges and the need for sustainable efforts
