Abstract

Infection caused by hepatitis B virus (HBV) is still a major global health problem and can cause liver cirrhosis and hepatocellularcarcinoma as well. Telbivudine is one among the drugs used to treat the disease routinely. However, using this drug in a long term therapymight cause mutations in HBV polymerase gene that decreases the effectiveness of the therapy. Here with the researchers report the geneticvariations of the gene isolated from telbivudine-which is used treated chronic hepatitis B patients in Surabaya, Indonesia. The blood serawere collected at Dr. Soetomo hospital from 10 telbivudine-treated and 10 untreated chronic hepatitis B patients. The DNA viral wasisolated and purified from each serum. Sequence polymerase gene at nucleotides 455 to 796 was amplified by PCR, and then analyzedbio informatically to determine their mutation profile. This study revealed a point mutation in HBV25 sample at nucleotide A1525G thatgives rise to I509V modification. Such mutation is also observed in a sequence that is available in Gen Bank with an accession numberAY641562. Additionally, the researchers found point mutations A1554G, T1593C, and C1629T in HBV25 sample and a point mutationA1554G in HBV20 sample. However, these mutations are silent. To conclude, the mutation in HBV polymerase gene among telbivudinetreatedchronic hepatitis B patients in Surabaya is known as A1525G.

Abstract

Chronic activivity of Hepatitis B Virus (HBV) infection can lead to liver cirrhosis or hepatocellular carcinoma. The objective of thisstudy was to know by analyzing the distribution of HBV genotypes and subtypes from hepatitis B patients suffering from chronic activehepatitis B infection in Surabaya. The HBV genotypes were determined by comparing the S gene sequences to those kept in the GeneBank. The phylogenetic tree was constructed by means of the unweighted-pair group method using arithmetic averages. Furthermore,the subtypes were deduced based on the prediction of amino acid residues 116 to 183 of HBsAg on multiple sequences alignment withClustalW2. This study involved 20 sera obtained from patients suffering chronic active hepatitis B infection. After PCR and sequencing,it was found that 13 samples could be used for sequence analysis. The results showed that all sequences were clustered into HBV genotypeB. The subtype adw2 was identified from 12 of 13 sequences, whereas one (1) belonged to ayw1. The subtype adw2 is most prevalent inIndonesia, namely in the islands of Sumatra, Java, South Kalimantan, Bali, Lombok, Ternate, and Morotai, while ayw1 is found in theislands of Nusa Tenggara and Moluccas. Based on this study, it was found that the patients with HBV subtype adw2 were from Surabaya, whereas with ayw1 was from Nusa Tenggara. It can be concluded that the HBV infected patients with chronic active hepatitis B inSurabaya have the genotype B with subtype adw2 which was originally from Surabaya, whereas, ayw1 was a patient originally fromNusa Tenggara.

Abstract

Glucoamylase, the enzyme which converts starch to dextrins and glucose, is used in the starch-processing industry, especially for the production of glucose crystal and high fructose syrup. The aim of this work was to produce glucoamylase by Aspergillus niger BCS using rice husk as solid substrate support. For this purpose, rice husk added to the mixture was optimized on a fixed weight ratio of cassava starch and rice bran. After that, using optimum rice husk concentration, optimization of the weight ratio of cassava starch and rice bran was carried out. Glucoamylase A. niger produced in this work was characterized by determining its optimum pH and temperature, its stability under various pH and temperature, its kinetic parameters, its hydrolysis products using soluble starch as substrate, and its molecular weights. The optimum conditions for glucoamylase production by A. niger obtained when the weight ratio of cassava starch: rice bran was 1:1 (dry basis, db) and the rice husk concentration in the fermentation medium was 20% by weight (db). Under these optimized conditions, enzyme units as high as 1774 U/g dry fermented substrate was obtained when fermentation was carried out for 5 days at 30°C. Optimum pH of glucoamylase A. niger was 4.5 and its optimum temperature activity was 65°C. This enzyme was stable at pH 3.0 - 7.0 and at a temperature up to 50°C.

Abstract

Correspondence is one of the most important things and is often done by every government agency, organization and office. It is still very rare for offices to process incoming and outgoing letters using virtual storage media, even though in the case of making the letter they already use a computer, but in terms of storing it is still done manually, it has not been stored computerized so that it will be very difficult, especially when searching for mail data that has been processed. pass. And not only in terms of storage that is carried out by the system with a computerized system, there are many other things that are very easy to do, including the approval process or letter signing which will be carried out in a structured manner, both incoming and outgoing letters. Because with the manual system the approval process will be complicated both time and effort. Based on the identification of this research, namely the implementation of the Incoming and Outgoing Mail Information System at the Bawaslu of Serang Regency based on a desktop using a qualitative research method with grounded research

Abstract

The purpose of this study was to analyze the PAI learning model in improving the character of students by using a social interaction model. The social interaction learning model focuses on the actual environmental setting so that students understand the essence of togetherness and diversity in living together in society later. In carrying out life in society, the ability to socialize is needed because we are social beings and cannot be separated from what is called social interaction with the community by being wrapped in religious norms. The research method used is descriptive qualitative. With a qualitative approach, researchers can observe, understand, and analyze accurately and comprehensively related to PAI learning with social interaction learning models to improve the character of students. The findings are as follows: a) The implementation of the social interaction learning model in PAI lessons in the classroom emphasizes problem-solving in small groups which will later illustrate the group results in front of the class, b) The PAI learning model using social interaction is very influential in improving the character of participants education that is realized by better social interaction and prioritizing Islamic norms.
