Kitosan sebagai Bahan Antibakteri Alternatif daim Formulasi Gel Pembersih Tangan

Masyarakat masa kini memiliki kesadaran yang tinggi akan kebersihan, termasuk kebersihan tangan. Namun beberapa jenis gel antiseptik pembersih tangan di pasaranmasih menggunakan alkohol sebagai bahan antibakterinya, alkohol dalam pembersih tangan dirasa kurang aman terhadap kesehatan. Maka sebagai alternatif yang cukup potensial untuk mengganti penggunaan alkohol pada gel antiseptik adalah kitosan melalui adsorpsi bahan aktifnya. Penelitian ini dibuat untuk mengetahui kemampuan antibakteri dari bahan kitosan dan membandingkannya dengan produk gel pembersih tangan pasaran dengan metode zona hambat menggunakan kertas cakram. Hasil uji konsentrasi hambat tumbuh minimum kitosan terhadap pertumbuhan bakteri menunjukkan bahwa media yang berisi biakan TPC dengan kitosan (hand chitosanitizer) memiliki zona bening yan g paling luas (9 mm), bahkan lebih luas dari zona bening yang dihasilkan oleh gel pembersih tangan pasaran (1 mm). begitu pula pada hasil biakan Escherichia coli dan Coliform zona bening yang paling luas dihasilkan oleh kitosan 0,75% (hand chitosanitizer) dengan zona bening (7 mm; 7 mm) dan zona bening yang dihasilkan oleh gel pembersih tangan pasaran (2 mm; 5 mm).</p

KARAKTER SPASIAL KORIDOR JALAN KAWASAN KAMPUS DALAM KONTEKS URBAN DESIGN DAN PERILAKU

UNSRI Bukit Besar has become a core area for decades that have a direct impact on the surrounding area, especially to the city's physical, economic, and social communities. The development and improvement of economic and social have triggered physical changes some urban elements that exist in the road corridor. The influence of this effect has some consequences for conflicts of interest in the use of road space. This research was conducted qualitatively by observing changes due to the existence UNSRI urban elements, which has occurred on the road corridors that restrict direct Campus Region. Mapping had been done to look at the physical condition that occurs when the lecture and after lecture and compare the results with theory and regulations. The results of this study as a reference in the control and development of the area as a result of the existence of  Campus of UNSRI Bukit Besar.</jats:p

Hydrophobic Pocket of SARS-Cov-2 Spike Glycoprotein are Potential as Binding Pocket

Abstract Coronavirus disease 2019 (COVID-19) caused by SARS-Cov-2 was recently spread all over the world. Spike glyprotein of SARS-Cov-2 (SARS-Cov-2 S-glycoprotein) is the main agent for host cell recognition. Finding the potential of binding pocket of S-glycoprotein may help to find the specific anti-coronavirus drug. Here we analysed potential binding pocket of SARS-Cov-2 Spike-glycoprotein which is suitable for anti-SARS-Cov-2. In pursuit this aim, dogsitescorer, site finder, and DEPTH were used for binding pocket prediction. Molecular interaction protein-ligands were performed using MOE 2009.10. Based on pocket prediction by Dogsitescorer, there are seven out of eleven pockets which have druggability score above 0.8. Molecular interaction studies revealed that interaction between six potential pockets and ligands resulted in negative scores at all. Our result shows that pocket_4 and pocket_6 are located on upper of SARS-Cov-2 S-glycoprotein and have big volume, 878.94 and 683.05 (Å3) respectively, yet lower number of hydrogen bond. Hydrophobic pocket zero, three, and five which is located in the middle of S-Glycoprotein have high number of interaction. These suggest that hydrophobicity of pocket and both upper and middle positions of S-Glycoprotein pocket are considered for developing anti-coronavirus drugs. We propose that hydrophobic pocket of SARS-Cov-2 S-glycoprotein is important for drug design.</jats:p

IMPLEMENTATION OF ONLINE ARABIC LEARNING IN THE NEW NORMAL ERA IN MADRASAH ALIYAH NEGERI 1 MUARO JAMBI

Abstract: This study aims to describe the implementation of online-based Arabic learning in the new normal era at MAN 1 Muaro Jambi. This research was conducted at MAN 1 Muaro Jambi in January-March 2021. This type of research was descriptive qualitative with phenomenological research type. The data from this study were obtained through observation, interviews and documentation as supporting data from the results of observations and interviews. The results of this study indicated that the implementation of online-based Arabic learning was carried out quite well, namely before the implementation of learning the teacher makes a lesson plan. In practice, the teacher used the madrasah e-learning application and whatsapp, the method used was the lecture and assignment method, The media used were pdf and photos of learning materials, the assessment carried out was an integrative assessment, which was a combination of knowledge, attitudes, and skills assessments. However, there were obstacles in the implementation of online-based Arabic learning, where there were students who did not have a device, the inability of students to buy quotas, the unstable internet network, there were many tasks that given by the teacher, the teacher found it was difficult to observe student development, and the lack of learning methods. The supporters of the implementation of online-based Arabic learning were the provision of free learning quota subsidies for students who did not have a device to ride with their friends or make assignments to madrasah so that there was an increase in the quality of teachers in utilizing technology.</jats:p

Implementation of Tourism Village Policy in Agusen Village, Gayo Lues Regency

This study aims to describe the implementation of the Qanun policy of Gayo Lues Regency Number 4 of 2016 concerning tourism, one of its contents is about the development, management and services of tourism that must be developed. One of them is the Agusen tourist village, which is located in Agusen village, Blangkejeren sub-district, the development which is still not optimal is a serious problem for the Gayo Lues district government to develop this Agusen tourist village. As for the focus of research from the implementation of local government policies regarding the Agusen tourism village, it focuses on communication, resources, disposition of implementers, bureaucratic structure and obstacles faced by local governments in the development and development of the Agusen tourism village object. This research uses qualitative methods using data collection techniques by observation, interviews and documentation. From the results of the study, it can be concluded that the communication that exists between the Gayo Lues district tourism office and the Agusen village government is going well, but the communication carried out with the Agusen village community does not go as desired, the implementation resources in development and development involve several related parties such as the local government agency. tourism in the Gayo Lues district, the Agusen village government, visitors, and the Agusen village community, the obstacles faced from the implementation of this policy are the lack of public awareness of the importance of developing this Agusen tourist village, and the lack of budget to develop and build this tourism object. The suggestion is that the local government and the Agusen village community work together to develop this Agusen tourist village both in terms of infrastructure, services and human resources.</jats:p
