Abstract

The aim of this research is to know about if the guava (Psidium guajava L.) leaf methanol extract on 10.5 mg/mL and 21.0 mg/mL dossages indicate a positive test as contraception antifertility to white mice (Rattus norvegicus). The sample is guava leaf from Mungkid, Magelang Central of Java Indonesia. The animals experiment are the white mice on 140-300 g for female, 200-250 g for male and about 3 months of age in average. The steps of this research are : (1) preparing  sample, i.e. washing, drying on to indirect sunlight and make the sample into powder, (2) isolation the guava leaf powder in soxhlet instrument with hexane, (3) evaporation the sample with rotary evaporator until guava leaf hexane extract produced, (4) maseration the sample with methanol, (5) evaporation the sample with rotary evaporator until guava leaf methanol extract produced, (6) conducting contraception antifertility activity test to guave leaf methanol extract on 10.5 mg/mL and 21.0 mg/mL dossages to mice white. The results of this research are guava leaf methanol extract on 10.5 mg/mL and 21.0 mg/mL dossages indicate a negative contraception antifertility test to white mice but in these dossages have indicated that an antiimplantation effect (the total natality of fetus is less than the total implantation site in mice white).

Abstract

The development of science and technology has brought significant changes to the world of education, especially in the teaching and learning process. In the learning process, there is an interaction between teachers and students to transform their knowledge in the learning environment. To convey this knowledge, a supporting factor in learning is needed, namely learning media. This study aims to determine the feasibility of chemistry learning media in the form of augmented reality (AR) media based on chemical tetrahedral representations on thermochemical materials. This study uses quantitative research methods, with data processing and analysis using the Aiken model. The instrument used is a validation questionnaire sheet to determine the feasibility of the media. The feasibility test itself is carried out by testing 1 chemist, 1 learning media expert, 1 learning technology expert, and 6 education practitioners. The results of the validation test of the feasibility of augmented reality media get the results of Aiken's V 0.9899, ​​which means that the media is feasible to use. However, improvements still need to be made according to suggestions from the validator so that the finalized product can be used as a measuring tool that meets the criteria.

Abstract

Recently, research on the chemistry of natural products as medicinal has been increasingly developed; this is because natural products have many chemical components, have the potential biological activities without side effects, and are easy to obtain. One of these natural products is Lempuyang Emprit (Zingiber amaricans BL.) essential oil. The researchers guided UKM Suti Sehati to develop a new product: a hand sanitizer containing Lempuyang Emprit essential oil (LEEO). This study aims to make ten hand sanitizer formulas by varying LEEO concentrations and determine the best formula based on the physical properties and antibacterial activities. The best formulation obtained was then optimized with variations in fragrance concentration. The best product was selected by a hedonic test using 30 untrained panelists based on the parameters of color, scent, texture, pH, homogeneity, speed of drying, causing no red skin, causing no pain, and causing no dry skin. The antibacterial activity tests were performed against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 using the disk method. The LEEO isolation was carried out using steam and water distillation methods, and the chemical components of the best product was identified using the GC-MS method. Based on the hedonic test, the best hand sanitizer product contains 1.5% LEEO and 3% fragrance. This product has a strong antibacterial activity value against S. aureus ATCC 25923, with an inhibition zone of 15.95 mm, and a moderate value against E. coli ATCC 25922, with an inhibition zone of 9.42 mm. The hand sanitizer product contains 21.35% of Zerumbone and exhibits antibacterial and antioxidant capabilities.

Abstract

UKM Herbal Suti Sehati merupakan salah satu UKM di Jawa Tengah yang mampu bertahan walaupun terjadi pandemi Covid-19. Tujuan kegiatan ini adalah untuk menyelenggarakan pendampingan di bidang produksi, pengemasan, labelisasi, perhitungan analisis kelayakan usaha, dan tata cara pengurusan ijin edar produk minyak atsiri lempuyang emprit (MALE) dan hand sanitizer beradisi MALE, terhadap UKM Suti Sehati, serta pemasaran produk-produknya melalui digital marketing. Permasalahan yang dihadapi oleh UKM adalah: 1) UKM belum memiliki alat distilasi uap-air guna mengisolasi MALE, 2) UKM belum bisa memproduksi MALE dan hand sanitizer beradisi MALE, 3) UKM perlu pendampingan pemasaran produk-produknya melalui digital marketing. Solusi guna mengatasi permasalahan yang ada di UKM adalah, Tim P2M melaksanakan: 1) pemberian hibah alat distilasi uap-air, 2) pendampingan produksi, pengemasan, labelisasi, perhitungan analisis kelayakan usaha dan tata cara pengurusan perijinan usaha produk MALE dan hand sanitizer beradisi MALE, serta 3) memberikan pelatihan digital marketing. Hasil dari kegiatan pelatihan dan pendampingan produksi minyak atsiri lempuyang emprit (MALE) dan hand sanitizer beradisi MALE serta pemasaran produk secara digital terhadap UKM herbal Suti Sehati adalah terwujudnya pemanfaatan tanaman lempuyang emprit yang banyak tumbuh di lahan milik UKM, menambah jenis produk yang dihasilkan oleh UKM, dan peningkatan pendapatan UKM.

Abstract

Coronaviruses have been known since 2002 in the case of SARS (Severe Acute Respiratory Syndrome). SARS-CoV-2, the cause of the COVID-19 pandemic, is believed to be an evolution of the SARS-causing coronavirus (SARS-CoV). This evolution shows the complex interaction dynamics between the virus and the host, which have characterized the emergence of new SARS-CoV-2 strain variations until now. Therefore, the search for these antiviral drugs is still critical. MPro is one of the important proteins for the life cycle of pathogenic coronaviruses, so it is an attractive target for developing drugs that inhibit this virus. This study examined the interaction of teicoplanin derivatives and vancomycin as SARS-CoV-2 MPro (6LU7) inhibitors through molecular docking with Autodock Vina. The smallest RMSD value was selected and stored to calculate the energy value. The image of atoms in the ligand and receptor was processed with Autodock Tools, LigPlus, and PyMOL. The study showed that teicoplanin derivatives such as teicoplanin aglycone, teicoplanin-A3-1, and vancomycin had the potential as SARS-CoV-2 Mpro inhibitors. Based on the interaction at the active site and the obtained ΔG values, even the teicoplanin aglycon had a more significant inhibitory potential than other potent inhibitors such as N3.
