From crisis to competence: A narrative inquiry into need-driven English learning in technical contexts
Get PDFThis Narrative Inquiry examines how Nikolas, a 55-year-old Indonesian vocational high school graduate, attained English proficiency and technical skills through informal digital learning, overcoming age barriers in SLA. Struggling to repair his son’s malware-infected laptop, he faced linguistic gatekeeping in English technical resources. Machine translation proved insufficient, driving him to learn English via digital literacy practices, utilizing YouTube, language apps, and online forums. His instrumental motivation evolved into sustained commitment as he accessed advanced materials and enrolled in a computer science program at the University of the People.Using Self-Determination Theory (SDT) and Cognitive Apprenticeship Theory (CAT), the study analyzes the self-taught technologist’s crisis-driven learning, showing how digital tools provided contingent scaffolding, fostering autonomy, competence, and relatedness. The research identifies fractal competence, task-specific proficiency developed to bypass linguistic barriers, and a reciprocal learning dynamic with his son, enriching both experiences.The determined father’s journey challenges intrinsic-extrinsic motivation dichotomies, demonstrating how pragmatic goals become identity-constitutive, leading to career advancement. His story highlights the potential of urgent, interest-driven adult learning, proving age irrelevant when motivation aligns with digital literacy. The study calls for policies recognizing informal learning, advocating inclusive technical education that integrates digital resources, supports autonomy, and validates experiential pathways
THE EFFECT OF ETHANOL EXTRACT FROM STROBILANTHES CRISPUS AGAINST C-REACTIVE PROTEIN IN DIABETIC RATTUS NORVEGICUS
Get PDFBackground : Diabetes Mellitus is a metabolic syndrome that causes various complications in the body due to various mechanisms of increased ROS and increased pro-inflammatory cytokines in the body such as IL-6, IL-1β, and TNF-α. The increase in numbers of pro-inflammatory cytokines and inflammation in the body can cause the formation of CRP which plays a role in the phagocytosis process and also increases the secretion of pro-inflammatory cytokines.Objective : The purpose of this research was to determine whether the administration of Keji beling’s leaves extract had an effect on CRP levels in diabetic rats.Method : This research used male Rattus novergicus wistar strain induced with diabetes using alloxan. The rats in the control group were given 0.5% Na CMC, ethanol extract of Keji beling’s leaves at a dose of 100 mg (P1), 400 mg (P2), and 600 mg/kg (P3) for 24 days and then the rat’s blood serum was examined for CRP using the CRP method which is Quantitative latex agglutination immunoassay using Nanopia CRP. Results : There were no significant difference in CRP levels between each group. The lowest levels of CRP were found in the extract group with a dose of 400 mg/kg (0.1± 0.0 mg/L), 600 mg/kg (0.12 ± 0.0447 mg/L) and the highest at 100 mg/kg (0.2 ± 0.2236 mg/L). Administration of a dose of 600 mg/kg had a significant effect on lowering blood glucose on diabetic rats (p = 0.047), giving a dose of 400 mg/kg also had an effect in lowering blood glucose but still not significant. The group which were given a dose of 100 mg/kg did not have an effect on lowering blood glucose.Conclusion : There were no effect on the administration of ethanol extract from Keji beling’s leaves on CRP levels in diabetic rats. Keywords : Keji beling, diabetes mellitus, CRP, antioxidants, blood glucose
THE COMPARISON OF SUPEROXIDE DISMUTASE LEVEL POST ULTRAVIOLET B EXPOSURE ON RATTUS NOVERGICUS WITH PHYSICAL AND CHEMICAL SUNSCREEN
No full textBackground: Ultraviolet radiation on the skin can result in the production of free radicals in the body. One of the defense mechanisms against free radicals is enzymatic antioxidants which are mainly mediated by superoxide dismutase (SOD). However, with the increasing number of free radicals formed, it will reduce SOD levels in the body. Physical and chemical sunscreens protect the skin from exposure to ultraviolet light so as to prevent the formation of free radicals and prevent a decrease in SOD levels in the body.
Objective: To determine the difference in SOD levels after UVB exposure in white rats (Rattus novergicus) with physical sunscreen compared to white rats (Rattus novergicus) with chemical sunscreen.
Methods: This study used 28 Rattus novergicus which were divided into 2 treatment groups namely, a group with physical sunscreen SPF 30 (P1) and a group with chemical sunscreen SPF 30 (P2), and 2 control groups namely, a group exposed to UVB without sunscreen (K2). and the group without UVB or sunscreen (K1). UVB exposure was given to the research subjects for 300 minutes and the measurement of plasma SOD levels was carried out by ELISA.
Results: There was no significant difference in the mean SOD levels in all groups (p=0.436), with the mean SOD levels in group P1 was 179.03 U/mg prot, group P2 was 330.41 U/mg prot, group K2 was 291.34 U/mg prot, and the K1 group was 317.77 U/mg prot.
Conclusions: SOD levels after UVB exposure in the group with chemical sunscreen were not statistically proven to be higher than the group with physical sunscreen; SOD levels after UVB exposure in the group with sunscreen were not statistically proven to be higher than the group without sunscreen; SOD levels in the group without UVB exposure were not statistically proven to be higher than the group with UVB exposure.

STUDENTS’ ATTITUDES TOWARDS THE IMPLEMENTATION OF ONLINE LITERACY PROGRAM IN PREPARATION FOR MINIMUM COMPETENCY ASSESSMENT
Get PDFTo date, studies on literacy programs in Indonesia have been ubiquitously conducted. However, little effort has been made to investigate junior high school students’ attitudes toward the implementation of online literacy programs as part of School Literacy Movement in the Indonesian context. Thus, to fill in the gap, this study aimed to investigate students’ attitudes towards the implementation of the Online Literacy Program in the Junior High Public School (JHPS) 1 Central Java as a program to promote School Literacy Movement and prepare the students to face Minimum Competency Assessment along with some challenges faced by the students as factors that might negatively impact their attitudes. To achieve the aforementioned aims, a mixed-method design was employed in this research. A questionnaire encompassing closed and open-ended questions was administered as the data gathering technique to provide triangulation and increase the validity and reliability of the research. Two main findings were drawn from this study. First, the participants showed a positive attitude towards the implementation of the program which is reflected in the two components of attitude namely, affective and cognitive domains. Secondly, despite the positive results, some challenges such as technical disruption and reading comprehension difficulty were still present during the program implementation. Two main recommendations were suggested to help the teachers improve the future program, namely (1) exploring broader topics and (2) providing more visual aids

57-YEAR-OLD WOMAN WITH OESOPHAGEAL VARICES AND SUSPECTED NON- CIRRHOTIC PORTAL HYPERTENSION
Get PDFNon-cirrhotic portal hypertension (NCPH) is characterized by portal hypertension, splenomegaly, hypersplenism, and pancytopenia without histological evidence of cirrhosis. Causes include chronic infection, toxin exposure, thrombophilia, immunological disorders, and genetic abnormalities. The diagnosis of NCPH remains challenging because symptoms often mimic cirrhotic portal hypertension and access to definitive tests such as liver biopsy is limited. We report the case of a 57-year-old woman with upper gastrointestinal bleeding and oesophageal varices without clinical or radiological signs of cirrhosis. Conservative management with variceal ligation and beta-blockers was used because advanced procedures such as transjugular intrahepatic portosystemic shunt (TIPS) were not available. This case demonstrates the challenges in diagnosing and treating NCPH in resource-limited settings and the importance of supportive care and early detection
AKINETIC MUTISM AS A NEUROPSYCHIATRIC SYMPTOM OF PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY : A COMPLICATIONS OF HUMAN IMMUNODEFICIENCY VIRUS (HIV) INFECTION
Get PDFProgressive Multifocal Leukoencephalopathy (PML) is a rare complication of Human Immunodeficiency Virus (HIV) infection. The disease carries a poor prognosis, with rapid progression and death usually occurring within 6 months. Mental disorders are a fairly common symptom in patients with PML (1/3 of cases). A 39-year-old male came with akinetic mutism. He has difficulty communicating, is unwilling to speak, has lost voluntary movements, and lacks motivation and initiative to perform daily activities. Managing this case is quite challenging, requiring careful history taking, physical examination, and selecting appropriate supporting tests. The management of this case involves a neurologist, internist, psychiatrist, and nutritionist. Correct diagnosis and treatment lead to clinical improvement. On the 15th day of treatment, the patient began to speak briefly with his family. Furthermore, his sleep has improved. Recognising this rare case earlier can be a clinical experience if at some point a similar case is found.
