THE RELATIONSHIP BETWEEN PLATELET-LYMPHOCYTE RATIO (PLR) AND NEUTROPHIL-LYMPHOCYTE RATIO (NLR) WITH HELICOBACTER PYLORI INFECTION IN CHILDREN
No full textObjectives
Helicobacter pylori (HP) is a common cause of gastritis in children, inducing a low-grade systemic inflammatory response through pro-inflammatory cytokines. Previous studies have demonstrated a correlation between inflammatory mediators and H. pylori infection. This study aims to investigate the relationship between neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with Helicobacter pylori gastritis in children.
Methods
This study enrolled sixty children aged two months until eighteen years diagnosed with gastritis who underwent a Campylobacter-like Organism (CLO) test following endoscopy. Patients were categorized into HP positive and HP negative groups. NLR and PLR were obtained from routine blood tests and analyzed for their association between the two groups.
Results
Of the sixty patients, 65% were girls, with a mean age of 11.43 ± 3.66 years. The study found a median NLR of 1.29 (IQR 0.68–2.97) and a mean PLR of 118.27 ± 36.64. The median NLR in the HP positive group (1.53 [0.84–2.64]) was higher than in the HP negative group (1.19 [0.68–2.97]), although the difference was not statistically significant (p = 0.569). A similar trend was observed for PLR, with a higher mean in the HP positive group (120.72 ± 44.6) compared to the negative group (115.82 ± 27.06), but without significant difference (p = 0.610). There were no significant differences between the two groups in hematological parameters such as hemoglobin, platelet count, leukocytes, neutrophils, or lymphocytes (p > 0.05).
Conclusion
Although NLR and PLR are accessible and cost-effective biomarkers, their inability to accurately predict H. pyloriinfection indicates that they are not yet suitable to replace or support conventional diagnostic approaches76 PagesTesis Magiste
The Juridicial Analysis of Unlawful Acts Regarding the Issuance of Pre-Auction Process Notification Letter (Case Study: Amurang District Court Decision Number 120/Pdt.G/2020/PN Amr Dated June 9, 2021 Juncto Manado High Court Decision Number 114/Pdt/2021/PT Mnd Dated November 3, 2021)
No full textIn banking practice, the legal relationship between debtors and creditors in credit agreements often gives rise to problems, particularly in cases of default that result in the execution of collateral through auction. One administrative step typically taken by creditors prior to auction is the issuance of a Pre-Auction Process Notification Letter. One of the cases examined in this study is Decision No. 120/Pdt.G/2020/PN Amr of the Amurang District Court, where the creditor unilaterally issued a Pre Auction Process Notification Letter. The research is guided by the following problem formulations: How is the process of submitting a collateral auction request from the debtor to the creditor conducted? What are the obstacles in the auction process of collateral between debtor and creditor?How did the judge consider the auction process of collateral based on Decision No. 120/Pdt.G/2020/PN Amr?
The method used in this thesis is normative juridical research with a descriptive nature, employing a statutory approach. The data used are secondary data as the primary source, collected through literature study and analyzed qualitatively, along with a case approach based on the relevant court decision.
The results of this research show that the panel of judges at the Amurang District Court, in Decision No.
120/Pdt.G/2020/PN Amr, deemed the defendant's actions (PT BPR Prisma Dana) in issuing the Pre-Auction Process Notification Letter without prior summons, without clear debt details, and without considering the renewed verbal
credit agreement, to be an unlawful act fulfilling the
elements of Article 1365 of the Indonesian Civil Code. On that basis, the court partially granted the plaintiff's claim and rejected the defendant's counterclaim in full. However, at the appellate level, the Manado High Court through Decision No. 114/Pdt/2021/Pt Mnd granted the defendant's appeal on the grounds that the debtor remained in default and that the auction process followed proper procedures.
Nevertheless, the High Court's considerations are viewed as insufficient in acknowledging the good faith and existence of a valid verbal agreement. The contrast in judicial reasoning between the two court levels reflects the critical importance of consistent application of the principles of justice, prudence, and legal protection in resolving credit agreement disputes.123 PagesSkripsi Sarjan

A Comparative Study on Notary Self-Publication or Self-Promotion and Its Supervision in Germany and Indonesia
No full textJob promotion is strictly prohibited for notaries, as explicitly stated in the professional code of ethics. Notaries are forbidden from engaging in self-promotion through print media, congratulatory flower arrangements, or any other forms of advertisement. This study addresses three key issues: (1) How are the legal regulations regarding notary self-promotion structured in Indonesia and Germany? (2) How is the supervision of notary self-promotion conducted in both countries? (3) What is the urgency of reforming the regulations and supervision of notary self-promotion in Indonesia in the future.
This research employs a normative juridical approach with a descriptive-analytical method. Data collection relies on literature and document studies (documentary study).
The findings of this study reveal that: (1) Legal regulations concerning notary self-promotion in Indonesia and Germany are explicitly governed by the 2015 Notary Code of Ethics and the German Federal Notarial Act (Bundesnotarordnung - BNotO).
(2) In Indonesia, the supervision of notary self-promotion is conducted by the Notary Honorary Council (Dewan Kehormatan Notaris - DKN), which oversees ethical compliance both within and outside the professional scope. In Germany, supervision is carried out by judicial authorities in each federal state and the Notary Chamber (Notarkammer) in accordance with the provisions of the BNotO. (3) The urgency of reforming Indonesia's regulations on notary self-promotion and supervision is essential to uphold professionalism, integrity, and independence within the profession.
Globally, supervisory practices vary significantly, with Germany implementing stricter sanctions and a more structured monitoring system. This study recommends harmonizing Indonesia's Notary Law (UUJN) with the Notary Code of Ethics, strengthening regulatory frameworks and oversight mechanisms, and enchancing public awareness through the Indonesian Notary Association (Ikatan Notaris Indonesia - INI) to ensure compliance with ethical standards.159 PagesTesis Magiste
Free Vibration Monitoring System on Wind Turbine Blades Using Internet of Things-Based Micro-Electro-Mechanical Systems Accelerometer Sensors
No full textVibration monitoring of wind turbine blades is critical for detecting structural damage
that affects system performance and stability. This study developed a real-time
vibration monitoring system using an ADXL345 MEMS accelerometer and ESP32
microcontroller integrated with the Blynk IoT platform. Vibration data were analyzed
using Fast Fourier Transform (FFT) to identify dominant frequencies indicative of
system conditions. Results showed that at 5 m/s wind speed, a natural frequency of
3.29 Hz on the Z-axis was detected — representing free vibration following abrupt
airflow cessation. At 6–7 m/s, dominant frequencies of 1.53–1.69 Hz on the X and Z
axes emerged, indicating mechanical resonance due to aerodynamic excitation
matching the system’s natural frequency. The developed system successfully provided
early warnings via real-time Blynk alerts and LED indicators, enabling preventive
maintenance before structural damage occurs. This research demonstrates that a
cloud-independent IoT approach is effective for condition monitoring of small-scale
wind turbines82 PagesSkripsi Sarjan

PM2.5 and SO₂ Monitoring System and Acid Rain Impact Analysis on Soil pH around Pangkalan Susu Power Plant Integrated with Internet of Things (IoT)”
No full textAir pollution caused by sulfur dioxide (SO₂) emissions and fine particulate matter
(PM2.5) had the potential to cause acid rain, which affected soil quality, particularly
soil pH. This study aimed to design and develop a microcontroller-based air quality
monitoring system integrated with Internet of Things (IoT) technology to monitor
PM2.5 and SO₂ concentrations as well as soil pH in real-time around the Pangkalan
Susu coal-fired power plant (PLTU). The system utilized GP2Y1010AU0F, MQ-136,
and soil pH sensors, with data visualized through the Blynk platform. A 14-day
monitoring period was conducted, and the results showed that PM2.5 and SO₂ levels
in Tanjung Pasir were significantly higher than in Lubuk Kasih, with PM2.5 peaking
at 176.55 µg/m³ and SO₂ at 4 ppm. This resulted in a decrease in soil pH in Tanjung
Pasir to an average of < 5.8, while Lubuk Kasih remained stable above 6.5. Pearson
correlation tests indicated a strong and significant negative relationship between
PM2.5, SO₂, and soil pH in Tanjung Pasir (r = –0.750 and –0.798; p < 0.01). This
study demonstrated that the designed system was capable of detecting acid rain
potential and its impact on soil, and showed potential for long-term environmental
monitoring applications.175 PagesSkripsi Sarjan
