The skin is the widest organ that makes up the human body which is the outermost and covers the entire surface of the body. The outermost location causes the skin to receive stimulation for the first time such as touch stimulation, pain, or bad influences from outside. This causes the skin to stretch due to disease. One of the most common skin diseases suffered by people is acne. Acne occurs generally triggered by the bacterium Propionibacterium acnes (gram positive bacteria). Effective acne treatment can use antibiotics, but inappropriate use of antibiotics can lead to resistance. Therefore it is necessary to have alternative therapies from plants that have the potential as antibacterial. One of the natural ingredients from plants that have antibacterial properties is mangosteen (Garcinia mangostana Linn.)This research was conducted using a descriptive experimental method with the aim of knowing the presence of antibacterial activity in cream preparations of ethanol extract of mangosteen rind (Garcinia mangostana Linn.) against Propionibacterium acnes bacteria as seen from the inhibition of bacteria with varying concentrations of 10%, 15% and 25% by using paper disc diffusion method and solid liquid dilution method. The positive control used clindamycin cream and the negative control used 1% DMSO. Analysis of the diameter of the inhibition data was carried out using the One Way ANOVA test. The preparation formulation that has the largest diameter in the diffusion test is F3 with a concentration of 25% with an average inhibition of 6.36 in the medium category.  The MIC and KBM values in the dilution method were at a concentration of 12.5%. The results of a normally distributed One Way ANOVA are measured with a value (P> 0.05). Mangosteen peel extract (Garcinia mangostana Linn.) has antibacterial activity against Propionibacterium acnes bacteria.    

This study evaluates the effectiveness of natural materials as antimicrobial agents in the treatment of freshwater fish diseases, with the aim of offering a safer and more sustainable alternative to synthetic chemicals and antibiotics. Using the literature review method, this study analyzed relevant current scientific articles. Results showed that extracts of betel leaf, neem leaf, cinnamon essential oil, basil essential oil, aloe vera, and propolis had significant antimicrobial activity against freshwater fish pathogens such as Flavobacterium columnare and Aeromonas hydrophila. Betel leaf extract and cinnamon essential oil showed inhibition rates of up to 85% and 82%, respectively. The advantages of using natural ingredients include environmental safety, reduced risk of antimicrobial resistance, and immunostimulating effects in fish. However, challenges such as ingredient availability, cost, and standardization still need to be addressed. This study suggests the development of natural ingredient-based products, standardization and quality testing, further research, and training for fish farmers. Collaboration between stakeholders is also important to reduce dependence on antibiotics. In conclusion, natural ingredients have great potential as effective and environmentally friendly antimicrobial agents in freshwater fish health management.

Bay leaf extract also has benefits as a natural insecticide. One way to improve the body's immune system is by consuming substances or substances that are immunomodulatory. Immunomodulators are substances or drugs that can modulate the function and activity of the immune system. Immunomodulators can be obtained from traditional medicinal plants, such as turmeric, ginger and galangal. These three plants are native to Indonesia and have been used for generations to relieve various diseases. The aim of this community service activity is to provide education to elderly people about the use of bay leaves and galangal in relation to immunity and natural insecticides at Posyandu Beringin V, West Kedungwuni District.

Red onion skin is one of the wastes that can be used as a natural dye because it contains anthocyanins which are one of the natural color pigments. The availability of red onion skin waste is very abundant, especially from household waste and industrial waste which has not been optimally utilized. The purpose of this study was to determine the effect of fixation type with different dyeing times on the color quality of batik fabric. This research method is an experiment by varying the fabric treatment in the pre-mordanting process, time variations of 30 and 60 minutes, and fixation variations, namely alum, arbor, and quicklime. The results of the study obtained that red onion skin extract is very good as a natural dye for dyeing batik fabric, the value of the color fastness test at 40 ℃ soap washing and cloth rubbing (wet) shows good quality with an average value of 4 and 4 - 5. The value of the L *, a *, b * color difference test and the results of visual observations on the pantone color produce an orange-red color that contains dominant color elements towards reddish and yellowish.

Nanotechnology is currently growing rapidly due to its broad application in science and technology. Nanotechnology itself is a science based on nanoparticles, so a more environmentally friendly method is being developed, namely the "green synthesis" method using plant extracts as a bioreductor. Silver nanoparticles have been synthesized using extracts of bidara leaf as a reducing agent. The objective of this research was was to determine the synthesis of silver nanoparticles using bioreductors and their application as antibacterial agents using bidara leaf extract against Staphylococcus aureus bacteria. This research used the green synthesis method to produce silver nanoparticles. The bidara leaf extract used was divided into several concentrations, namely 1 mM, 2 mM, 3 mM and 4 mM. To characterize silver nanoparticles, UV-Vis and PSA spectrophotometers were used. Furthermore, the Kirby-Bauer method was used to test the antibacterial properties of silver nanoparticles against Staphylococcus aureus bacteria. The results of research that has been done show that the formation of silver nanoparticles is characterized by the emergence of maximum absorbance peaks in the wavelength range of 400-450 nm, while the PSA results at concentrations of 3 and 4µm showed nanoparticle sizes of 185 nm. Silver nanoparticles of bidara leaf extract with various concentrations of 1 mM, 2 mM, 3 mM and 4 mM have antibacterial activity that can inhibit the growth of Staphylococcus aureus bacteria with an average inhibition zone diameter of 13.0617 mm, 11.7333 mm, 9.05 mm and 13.19 mm. This shows that silver nanoparticles with bidara leaf extract have antibacterial properties.

Universities certainly have a lot of important documents stored. Documents stored include scientific works in the form of journals. The journal that is kept has an identity so that if needed it will make it easier for people to find it. A library is a place to store scientific work, both in the form of journals and for storing other documents. The problem currently occurring is that there are so many documents or journals stored that it takes a long time for people who want to find information related to journals. The aim of this research is to provide a solution to make it easier for people who want to find information about many journals. The method proposed in this research is to use the information extraction method. Information extraction is the search for structured information such as entities and attributes. The stages carried out start from collecting the dataset which is then carried out preprocessing where this stage takes the form of converting documents with PDF extensions to documents with HTML extension. Apart from that, at this stage data cleaning is also carried out, meaning that at this stage it will be possible to create new paragraphs. Therefore, the new paragraph needs to be removed. Then the next stage is rule-based information extraction based on keywords and rules. The results of this research are that none of the 50 journal abstract documents failed so that the accuracy obtained was 100%. So the information extraction in this research can be used to search for information from journal abstracts.

Music genre classification is one part of the music recommendation process, which is a challenging job. This research proposes the classification of music genres using Bidirectional Long Short-Term Memory (BiLSTM) and Mel-Frequency Cepstral Coefficients (MFCC) extraction features. This method was tested on the GTZAN and ISMIR2004 datasets, specifically on the IS-MIR2004 dataset, a duration cutting operation was carried out, which was only taken from seconds 31 to 60 so that it had the same duration as GTZAN, namely 30 seconds. Preprocessing operations by removing silent parts and stretching are also performed at the preprocessing stage to obtain normalized input. Based on the test results, the performance of the proposed method is able to produce accuracy on testing data of 93.10% for GTZAN and 93.69% for the ISMIR2004 dataset.
