Teresa Martuah Purba — 2025-12-27

The alleged diploma forgery case involving Joko Widodo attracted great attention on social media, especially on the X platform. This research aims to analyze people's association with the issue by utilizing the Naive Bayes algorithm. The data used in this study consists of 1,000 tweets obtained through web crawling techniques based on certain keywords. The dataset is divided into two segments, 80% used for training data and 20% used for testing data. Of the 800 data used for training, 299 tweets (37.4%) showed positive sentiment, and 501 tweets (62.6%) showed negative sentiment. The remaining 200 tweets were used to test the model. The Naive Bayes model was then trained with the training data to identify existing sentiment patterns, and then tested with the test data to assess its classification accuracy. The findings of this study indicate that negative sentiment is superior to positive sentiment regarding the issue of Joko Widodo's diploma forgery. This reflects the public's tendency to respond to politically sensitive issues in the digital world. The Naive Bayes method proved to be quite powerful in classifying text-based public opinion with high accuracy, so it has the potential to become a tool in mapping public views on socio-political issues.

Katarina Eteta br Ginting — 2025-12-27

The Community Health Center is a primary healthcare facility that provides medical services to the public. However, at the Munte Community Health Center, the patient queuing process is still carried out manually by recording names in a registration book, which leads to various issues such as long queues, disorderliness, and delays in service delivery. This study aims to design a web-based queue information system to improve service efficiency, facilitate the registration process, and streamline patient calling. The development method used is the waterfall model, which includes the stages of requirement analysis, system design, implementation, and testing. The results of the study produced a queue information system that enables digital patient registration, patient data management, and automatic patient calling based on sequence, with access through a local network and an interface designed to be simple for staff to use. Testing shows that the system functions well, reduces patient waiting time, and improves service flow. Thus, this web-based queue information system is expected to support the provision of more effective, efficient, and comfortable healthcare services at the Munte Community Health Center, as well as promote the realization of digital transformation in healthcare services.

Hubungan Urinalisis (Leukosit dan Nitrit) dengan Kultur Urin untuk Deteksi Infeksi Saluran Kemih (ISK) di RSUD dr Pirngadi Medan Periode Juli 2024 – Juni 2025

Renatha Nainggolan — 2025-12-31

Introduction: Urinalysis is a basic test for patients with urinary tract infections (UTIs). Ninety-five percent of UTIs are caused by E. coli. The incidence rate of UTIs in Indonesia among adolescents aged 10-18 years is 35%-42%, and among young adults aged 19-22 years is 27%-33%. UTI diagnosis is confirmed by urine culture, where a bacterial count of > 10⁵ colonies per milliliter (cfu/ml) is detected. Urinalysis reveals leukocyturia and positive nitrite. Bacteria capable of converting nitrate to nitrite include Escherichia coli, Enterobacter, Citrobacter, Klebsiella, and Proteus species. Method: This study used an observational analytical study with a cross-sectional design and retrospective approach. The study sample consisted of UTI patients who underwent leukocyte, nitrite, and urine culture tests recorded in the medical records of the Clinical Pathology Department at Dr. Pirngadi General Hospital in Medan. Out of 60 urine culture samples, 12 samples showed no bacterial growth. Results: The results showed that the majority of UTI patients were female, totaling 36 individuals (60%), compared to 24 males (40%). The age group of 51-70 years (54%) had the highest number of UTI patients. Positive leukocytes experienced UTI (68.8%) compared to negative leukocytes P-value 0.001. Positive nitrites experienced UTI (58.3%) compared to negative nitrites P-value 0.001. In this study, the most common bacteria causing UTI were Klebsiella pneumonia (43%), Enterococcus faecalis (17%), and Escherichia coli (8%). Conclusion: In 60 urine culture samples, the most common bacteria causing UTIs were Klebsiella pneumonia (43%), Enterococcus faecalis (17%), and Escherichia coli (8%). Leukocytes were positive in 68.8% of cases of UTI compared to leukocytes that were negative, P-value 0.001. Nitrites were positive in 58.3% of cases of UTI compared to nitrites that were negative, P-value 0.001

These results highlight the need for improvements in service quality, system stability, and recommendation accuracy to enhance overall user satisfaction among students.

Penanganan Multidisiplin Tuberkulosis Paru Multi-Drug Resistant Diseminata dengan Spondilitis Tuberkulosis Thorakolumbal dan Komplikasi Paraparesis Berat

Budi Jefri — 2025-12-31

Background: Multidrug-resistant (MDR) tuberculosis (TB) is a global challenge. Tuberculous spondylitis (Pott's disease) is the most devastating extrapulmonary manifestation. Cases of MDR pulmonary TB with vertebral involvement and severe neurological complications require aggressive and coordinated management.

Case Presentation: We report the case of Mr. RP, a 22-year-old man diagnosed with MDR pulmonary TB and MDR tuberculous spondylitis of the thoracic-lumbar spine (Th3-Th4). The patient presented with progressive upper motor neuron (UMN) paraparesis (motor 2/5), back pain (since 7 months), hypoesthesia around Th5-6, and autonomic dysfunction (urinary/defecatory disorders). The diagnosis of MDR TB was confirmed by TCM sputum (MTB detected, Rif Res) and confirmed by Rif Res findings in cerebrospinal fluid (CSF). Thoracolumbar MRI showed compression and destruction of Th3-Th4 vertebral bodies, kyphotic alignment, paravertebral masses, and Th3 spinal cord edema. The patient also had subclinical hypothyroidism and hyperuricemia.

Management: The patient received a long-term regimen of MDR-TB therapy (Bedaquilin, Levofloxacin, Linezolid, Clofazimine, Cycloserine, Vitamin B6, N-Acetylcysteine). One week after initiation of anti-TB treatment, a decompressive laminectomy, posterior fusion, and biopsy were performed on November 7, 2024.

Results: At the 6-month follow-up (April 28, 2025), the patient demonstrated dramatic neurological improvement, able to walk independently with full muscle strength (Motor 5/5) in all extremities.

Conclusion: This case underscores the importance of early diagnosis of disseminated MDR-TB and the success of a combined therapeutic approach, namely immediate surgical decompression followed by aggressive and appropriate MDR-TB therapy, in achieving optimal functional recovery.

Increased nutritional needs among adolescent girls are influenced by rapid physical growth and development, as well as changes in lifestyle and dietary habits that affect nutrient intake. Adolescence is a nutritionally vulnerable period, and anemia is one of the most common nutritional problems in this group. According to Riskesdas 2018, the prevalence of anemia among adolescent girls in Indonesia is 48.9%. This study aimed to examine the effect of counseling using leaflet media on adolescent girls’ knowledge of blood supplement tablets at SMK Dharma Patra, Pangkalan Susu District, in 2024. A pre-experimental study with a one-group pretest–posttest design was conducted involving 79 tenth-grade female students selected through stratified random sampling. Data were analyzed using the Wilcoxon test. The results showed that the mean knowledge score increased from 54.05 (SD 8.810) before counseling to 87.59 (SD 7.065) after counseling, indicating an average increase of 33.54 points. Statistical analysis revealed a p-value of 0.000 (<0.05), demonstrating a significant effect of leaflet-based counseling on improving adolescent girls’ knowledge in anemia prevention. Therefore, it is recommended that schools and local health centers utilize leaflet media when delivering nutrition education to students.
