Abstract

Chitinase is an enzyme that degrades chitin on β-1,4-acetamido-2-deoxy-D-glycoside bound to produce Chitin oligosaccharide or its soluble monomer, N-acetylglucosamine (NAG). Chitinase are usually produced naturally by chitinolytic microorganism that are found in soil or water environment. Chitinase have been widely used for biocontrol agents of plant pests. The product from chitinase hydrolysis can be used as antiinflammatory agent and anti hyperpigmentation. This research was aimed to screen and evaluate the chitinolytic ability of 9 isolate. The best isolate was the one which produced high chitinolytic activity and hydrolyzed chitin into NAG. 9 isolate were examined and BPPTCC-2 was the best isolate which produced highest level of chitinolytic activity 0.1780 U/ml. The chitinase was able to hydrolyzed chitin resulting high yields of NAG 11.5% as the only product.

Abstract

In this article, we explain several things related to the concept of nasiyah in QS. Al-Alaq verses 15-16. This study uses a qualitative research approach to the type of literature (library research). Sources of data taken in this study are scientific journals and articles that support and are relevant to the title of this article. According to the commentators Nasiyah is the central crown where the orders of all the organs of the human body. In Nasiyah (the crown) it is based on character, because the owner of the crown is the cause of an action. Nasiyah itself does not just mean the crown but also includes the entire human body. Then the relationship between character formation and the human brain is a character located in the frontal lobe and parietal lobe. Based on the views of commentators and scientific scientists on the meaning of nashiyah in the Qur’an, that when the crown is damaged, this will have an impact on changes in human behavior and mindset. When in the afterlife humans are physically tortured, the first and foremost organ of the body that will feel the torment is the crown. Because, the crown is what will give the color of good and bad to human actions.

Abstract

Iron deficiency anemia (IDA) is a health problem in Indonesia. Prevention and treatment of IDA is carried out by giving fortified foods and oral iron therapy. Both can use ferrous fumarate which is made with reacting bivalent iron and disodium fumarate. Bivalent iron can be obtained from iron sand in Indonesia. This study aims to synthesize ferrous fumarate from Indonesian iron sand, which is from Malang, Sukabumi, and Cianjur area, and to determine its absorption through in vivo body weight gain test in male Wistar white rats (Rattus norvegicus). First, ferrous fumarate was synthesized through reaction of ferrous sulfate, which was made from Indonesian iron sand with the highest iron content, which was from Sukabumi area, and disodium fumarate. Second, in vivo body weight gain test was conducted to 3 rat groups (negative control, ferrous sulfate group, and ferrous fumarate group, respectively) and monitored for two weeks. The results showed that ferrous fumarate was successfully obtained as brownish red-orange fine powder with yield of 62.17 ± 1.66 %. In addition, the in vivo body weight test suggested that the rats from ferrous fumarate group showed similar weight gain (35.1%) compared to those from the ferrous sulfate group (30.6%), indicating a possibility of iron absorption from ferrous fumarate.

Abstract

Introduction/Main Objectives: The Merdeka Mengajar (PMM) Platform was developed to support the Merdeka Curriculum by offering flexibility for teachers in designing technology-based learning. It features independent training, diagnostic assessments, and digital resources aimed at improving learning effectiveness. Background Problems: : Despite its benefits, PMM implementation faces challenges such as limited technology access, low teacher proficiency in using the platform, and minimal supporting training. This study evaluates PMM’s effectiveness using the CIPP (Context, Input, Process, Product) model. Novelty: This study offers a comprehensive evaluation of PMM using the CIPP model. Research on PMM’s effectiveness in primary education remains limited, making this study a new contribution to understanding teacher use. Research Methods: A qualitative case study was conducted at SD Negeri 057/1 KM V Muara Tembesi. Data were collected through interviews with the principal and teachers, observations of PMM usage, and analysis of relevant documents. Finding/Results: PMM assists teachers in preparing materials, conducting assessments, and accessing digital resources. However, limited internet and training remain key barriers. Conclusion: PMM has the potential to enhance learning, but its success depends on infrastructure support and ongoing teacher training. The study provides recommendations for improving PMM implementation.
