Abstract

The way of life back to nature, including in the field of health, forms the habit of using plants as traditional medicine. Traditional medicine is indicated to be able to cure a variety of diseases. As with the leaves of Ciplukan (Physalis peruviana L.) by the people of Desa Wanasuka Kecamatan Pangalengan Kabupaten Bandung is considered to be used as a traditional medicine for inflammatory diseases such as rheumatism, asthma, and gastritis (maag) due to side effects and toxicity produced relatively small when compared with modern medicine. The aim of this study is to identify the potential of the secondary metabolite compound found in the leaves of the Ciplulan (Physalis peruviana L.) as a candidate for anti-inflammatory drugs. These research methods are molecular methods of docking through physical chemical properties testing, pharmacokinetic profiles of test compounds through site Pre-ADMET (Absorption, distribution, metabolism, excretion, and toxicity) and Lipinski Rule of Five. The results of this study showed that the binding affinity of caffeic acid compounds with PTGS2 receptors (PDB ID: 5F19) showed a more negative result compared to the comparative drugs Aspirin and Ibuprofen -7.4. There was a molecular interaction similar to Aspirin, in which the addition of amino acid residues from ASN 382 and TYR 385 produces a strong irreversible inhibition of PTGS2 (PDB ID: 5F19) and is predicted to inhibit prostaglandin H synthase and indicate that caffeic acid is capable of producing irreverible inactivation of PTGS2 (PDB ID:5F19). So potentially a candidate for a safer anti inflammatory drug for the body. Because it has almost the same or close potential as Aspirin against inflammatory diseases.

Abstract

This study aims to investigates the correlation between parenting styles and adolescent sexual behavior at SMA Negeri 3 Mataram using an observational analytic design with a cross-sectional approach. Data were collected from 69 11th-grade social science students via a questionnaire assessing parenting styles and sexual behavior. Results indicated that (1) 59.4% of respondents experienced permissive parenting, while 40.6% encountered democratic parenting; (2) respondents who have permissive parenting, 5.8% demonstrated negative sexual behavior, in contrast to the uniformly positive behavior observed in adolescents with democratic parenting; (3) the results of Fisher's exact test are a significance value of 0.141, indicating no statistically significant relationship between parenting styles and adolescent sexual behavior; (4) trend suggests that democratic parenting, which balances freedom and control, is associated with positive adolescent sexual behavior. Thus, these findings highlight the importance of promoting democratic parenting and comprehensive sexual education to reduce risky behaviors. Recognizing cultural nuances and enhancing parental involvement are essential for effective adolescent sexual health prevention strategies.

Abstract

Staphylococcus epidermidis is a gram-positive bacterium that can cause acne. It is part of the normal flora found on the skin and is non-pathogenic. Metabolite compounds such as tannins, saponins, triterpenoids, and flavonoids present in starfruit leaves and castor leaves have antibiotic properties. The aim of this study was to determine the effectiveness of the combination of starfruit leaf extract and castor leaf extract, and to identify the most effective concentration ratio of these extracts in inhibiting Staphylococcus epidermidis bacteria. The research method used was experimental, conducting in-vitro antibacterial activity tests against Staphylococcus epidermidis. The results of the antibacterial test using a combination of starfruit leaf extract and castor leaf extract showed that at the highest ratio of 1:3, it produced an average inhibition zone of 15.73 mm against Staphylococcus epidermidis bacteria. This result was higher compared to the positive control Clindamycin HCl.

Abstract

Teluk Nibung River in Batu Ampar District, Kubu Raya Regency is a transportation route for Mangrove Production Forests and a traditional fishing area for local communities. The community structure of phytoplankton in the Teluk Nibung River has never been reported. As the main producer in the waters food chain, the structure community of phytoplankton indicates the quality of the fertility of the waters. The community structure of phytoplankton can be identified by measuring the index of abundance, diversity, evenness and dominance. The survey method was used at three stations in dry and rainy seasons. Sample collection is using net plankton (30 µm) and preserved in 4% formalin. The physico-chemical factors measured included temperature, pH, brightness, current velocity, salinity, dissolved oxygen and CO2, phosphate and nitrate. Once identified, phytoplankton calculations are performed to obtain abundance, diversity, evenness, and dominance values. The species number of phytoplankton found was 56 classified into 6 classes, namely Bacillariophyceae (34 species), Dinophyceae (12 species), Chlorophyceae (4 species), Cyanophyceae (3 species), Xantophyceae (1 species), and Euglenophyceae (2 species). The highest abundance of phytoplankton was in the Bacillariophyceae class with a range of 583 Ind./L at Station 2 in the rainy season to 3.922 Ind./L at Station 3 in the dry season. The diversity index at the three stations and both seasons is in the moderate category with a range of 2.31-2.46. The evenness index at the three stations and both seasons is in the high category with a range of 0.67-0.73. Low dominance level was found at the three stations and both seasons with values ranging from 0.14 to 0.19. Overall, the community structure of the phytoplankton in the Teluk Nibung River is in relatively good condition and can support the life of the aquatic biota in it.

Abstract

Indonesia continues to be committed to improving the quality of human resources. This is realized through the Ministry of Education and Culture, which promotes and implements a curriculum that supports learning freedom. The application of this curriculum requires not only theoretical support but also more practical technical support, which cannot be ignored. In this regard, the Mandalika University of Education, especially the biology education department, has held workshops related to technical guidance for implementing the freedom to learn curriculum. However, it is essential to understand that there needs to be more information regarding the readiness of prospective biology teacher students to implement this curriculum. Therefore, this research was conducted to describe the level of readiness of prospective biology teacher students for independent learning. In this research, 53 prospective teacher students were involved voluntarily as respondents, including 42 women and 11 men, consisting of 12 (semester 1), 15 (semester 3), 17 (semester 5), and 9 (semester 7). The instrument used to measure the level of readiness for independent learning was adapted from the self-rating scale of self-directed learning (SRSSDL) questionnaire. Next, data regarding readiness for independent learning was analyzed descriptively and quantitatively. Based on the results of the analysis, it was found that 16.98% were not very ready (low or unprepared), 73.58% were not ready (moderate), and 9.43% were ready (high). These results also show that prospective biology teacher students have the same level of readiness for independent learning or that there is no significant difference in readiness for independent learning based on semester differences. Apart from that, of the SRSSDL components, self-awareness and learning activities have the lowest averages (32.51 and 32.09). Thus, our respondents (in this case, prospective biology teacher students) are not ready for independent learning. Regarding what will be done next, can be seen in the conclusions and recommendations section.

Abstract

Waste is an environmental problem caused by the activities of living things. The synthetic waste group or what is often found in the form of plastic and the like is a group of waste that is very difficult to degrade. This can be overcome by using lipolytic bacteria. This research aims to analyze lipolytic bacteria which can be used to biodegrade plastic waste in the Bonoloyo TPU, Makam Haji TPS, and the Bengawan Solo river flow. This research uses quantitative descriptive methods. Screening for lipolytic bacteria degrading polystyrene (PS) showed that the highest population of lipolytic bacteria isolated from public burial places of 15.6 x 104. Meanwhile, lipolytic screening with the highest average clear zone formed was 0.641 cm which came from TPS 1, then average -The highest average lipolytic index came from SBS 2 with a figure of 1.6525 cm, the largest average colony diameter came from TPS 1 soil samples at 0.45 cm. The degradative nature of bacteria on plastic above shows that the Bengawan Solo river has microbes with the highest ability compared to microbes from TPS and TPU, namely 22.42%. The degradation between TPU, SBS, and TPS is significantly the same. PS degradation in Bonoloyo TPU shows significant physical changes.

Abstract

Drinking water quality is a crucial factor that influences livestock productivity. Regular evaluation of the quality of livestock drinking water is an essential activity. Blitar Regency is known as a center for egg production from laying hens (Gallus domesticus). This study aims to evaluate the quality of livestock drinking water and provide a literature review regarding the potential for improvement through phytoremediation methods. This research method involves laboratory analysis and literature review. Laboratory analysis is carried out to determine the quality of water chemical parameters, then the results are compared with livestock drinking water standards regulated by Regulation of the Minister of Health of the Republic of Indonesia Number 32 of 2017. If a discrepancy is found with the standards, it is continued with a literature study regarding the use of phytoremediation methods as a solution. Analysis of chemical parameters, including ion levels, using a reagent kit with the help of Spectroquant Pharo 300 UV Vis spectroscopy. The results of the analysis involve iron, fluoride, manganese, nitrate, nitrite, cyanide, hardness, cadmium, zinc metal and sulfate. All parameters meet quality standards, except for Fluoride (F-) levels which exceed the threshold of 1.5 mg/L, caused by the use of groundwater sources or wells which have the potential to have higher mineral content than surface water. The potential impacts of high fluoride levels on laying hens include reduced egg production, impaired growth, reproductive disorders, decreased water consumption, and decreased body weight. The literature review highlights phytoremediation methods involving plants as an economical and effective solution. Afforestation, such as planting grass or bushes around livestock areas and wells, or through creating ponds with aquatic plants, can significantly reduce fluoride levels in livestock drinking water.
