Published: January 2025

Wontons consist of skin and filling. Generally, wonton skin is made from wheat flour, oil, water and salt. In this research, wonton skin was made with different characteristics by replacing wheat flour with tangmien flour. The wheat flour in wonton skin can be replaced 100% with tangmien flour because it has fine and soft characteristics which make the wonton skin color more transparent white and have a flexible texture. One effort to increase nutritional value and appearance is by adding green spinach (amarathus hybridus l.) juice. Green spinach contains chlorophyll which can be used as a natural coloring in food processing. Green spinach is mixed with 20gr, 40gr and 60gr of tangmien flour which is useful for changing the color of the wonton skin so that it has different color variants. Research Objectives: 1) To determine the sensory quality of wonton skin which includes color, texture, aroma and taste; and 2) To determine the nutritional content which includes energy, carbohydrates, fiber, iron, and vitamins A, B, C. This research uses an experimental method. The data collection technique was carried out by observation using a questionnaire sheet in the form of an instrument with 30 panelists. The data analysis technique used was single ANOVA followed by Duncan's test. To determine the nutritional content (energy, carbohydrates, fiber, iron, and vitamins A, B, C) laboratory tests are carried out. The results of the research show: 1) There is an effect of substitution of green spinach juice on the sensory quality of color and no effect on the sensory quality of texture, aroma and taste; and 2) The nutritional content of the product is Energy 305.80 kcal/100g, Carbohydrates 38.60%, Fiber 3.80%, Iron 2.85 mg/100g, Vitamin A 98.65mg/100g, Vitamin B 4.15mg /100g, Vitamin C 8.10mg/100g.

Published: January 2025

Background: Corona viruses affect both humans and birds. In humans, the symptoms vary from mild cough, sore throat to severe respiratory tract infection and respiratory distress. COVID-19 can be presented by cough, difficult breathing, generalized body aches, loss of smell and taste. The sudden loss of smell was described as a definitive diagnostic symptom of COVID-19 infection. This study was designed to investigate the histological changes of COVID19 on olfactory mucosal epithelium, which was associated with temporary or long lasting olfactory dysfunction.
Patients and Methods: This was a prospective study. Twenty patients with olfactory dysfunction few months after COVID 19 were included and represented the study group. In addition, 20 patients with olfactory dysfunction due to causes other than COVID 19 (e.g., allergic nasal polypi or to skull base fracture) were included as the comparison (control group). All were evaluated in a standard techniques. Then, Forty (40) nasal olfactory epithelium punch biopsies have been obtained under general anesthesia after taking a written consent. Data were recorded and compared between both groups.
Results: The Light Microscopic examination of biopsies in the study group showed inflammatory changes among 17 cases and atrophied changes among 3 cases, compared to 16 and 4 cases in the control group. The inflammatory changes were in the form of inflammatory lymphocytic cells, few macrophages, mast and goblet cells. There was no significant differences between groups regarding patient age, special habits, chronic diseases, complications after biopsy or the result of biopsy. However the duration of OD was significantly longer in the patient than the control group (6 (4-8) vs 2 (1-5) months).
Conclusion: COVID 19 invades nasal olfactory epithelium leading to reversible inflammatory changes that was presented as a reversible olfactory dysfunction. These changes did not differ significantly than other causes nasal inflammation.

Structural Evaluations of SARS-CoV-2 Main Protease (Mpro): A Review for COVID-19 Antivirals Development Strategy
Authors: Syaifullah Azmi Muhammad Hamzah , Giri-Rachman Ernawati Arifin 
Published: January 2025

It has been almost four years since the first case of COVID-19 emerged, and the antivirals that could work specifically against SARS-CoV-2with a high efficacy are still under development. Main Protease (Mpro) of this virus plays a crucial role in virion maturation during itsreplication within the host cell. This protein works together with the papain-like protease (PLpro) to cleave polyprotein 1a and 1ab into a total of16 functional fragments of non-structural protein. Antiviral with the ability to inhibit the activity of Mpro could potentially prevent the virion replication, and they can be developed to target the catalytic or allosteric site of this protein. Antiviral that works on the catalytic site will act as competitive inhibitors of the substrate peptide which leads to the loss of Mpro function. Targeting the allosteric site (e.g. distal site and dimerization interface) will cause allosteric modu- lation of the protomer which could alter the protein 3D conformation and disrupt the formation of homodimer structure. This will affect the geometry and surface structure of the catalytic site which in turn decreases the affinity of the substrate peptide towards the Mpro catalytic site, resulting in a completeinactivation of the protein. Mutation study of Mpro amino acids sequence also reveals that the mutation frequency for each amino acid position isextremely low and negligible. Moreover, it is found that this protein has 24 mutational cold spot residues scattered within its structure which could be targeted for the development of antivirals due to its highly conserved nature.

Published: January 2025

Kepadatan dan daya dukung tanah merupakan permasalahan yang harus diperhatikan dalam perencanaan struktur bangunan konstruksi. Hal ini disebabkan tanah berperan sebagai media yang menahan beban ataupun aksi dari konstruksi yang akan dibangun di atasnya. Perbaikan tanah dengan mencampurkan dua material merupakan salah satu cara untuk memenuhi kekuatan yang dibutuhkan. Perubahan cuaca dan suhu di lapangan menjadi faktor yang menjadikan tanah tidak stabil.
Perbaikan tanah yang dilakukan berasal dari Proyek pekerjaan Tol Pekanbaru – Bangkinang yang berasal dari empat lokasi pengamatan. Penelitian ini dilakukan dengan mencampurkan dua material tanah dengan perbandingan 1:1 dari lokasi yang berbeda. Setelah itu dilakukan pengujian CBR, Berat Jenis, Batas-batas Atterberg dan berat volume untuk setiap benda uji. Hasil penelitian berupa nilai CBR yang menunjukkan bahwa nilai CBR tertinggi berada pada tanah campuran Pasir 2 dengan Tanah 2 dengan nilai CBR 34.34 %. Nilai CBR terendah didapatkan pada campuran Tanah Pasir 1 dengan Tanah 1 dengan 21.5%. Campuran antara Pasir 1 dengan Tanah 2 memiliki nilai CBR 25.3%, sedangkan Pasir 2 dengan Tanah 1 memiliki nilai CBR 24.8% tidak terlalu jauh dengan Pasir 1 dengan Tanah 2. Kepadatan kering maksimum untuk pasir 1 tanah 1 adalah 1.944 Gr/cc. Pasir 1 dengan tanah 2 adalah 1.943 Gr/cc. pasir 2 dengan tanah 1 adalah 1.996 Gr/cc. Sedangkan pasir 2 dengan tanah 2 adalah 1.930 Gr/cc. Perbedaan relatif kepadatan kering maksimum dipengaruhi oleh ukuran butiran dan tidak dipengaruhi oleh energi pemadatan dan ukuran mold pada metode kepadatan ringan (standar).
