    No full text
    A notary is authorized to draw up an authentic deed for any act or agreement required or desired by the parties. A lease agreement is an agreement between two parties in which one party grants the enjoyment of an item to the other party for a specified period in exchange for payment agreed by the lessee. The research questions are: What are the legal provisions regarding lease agreements drawn up in the form of an authentic deed by a notary based on applicable laws and regulations in Indonesia. What are the obligations and responsibilities of a notary in applying legal provisions to the creation of lease agreements according to the UUJN. What are the legal implications of notary negligence in drawing up lease agreements that stipulate a term exceeding the validity period of the management rights. This research uses normative legal research with a descriptive and analytical approach. The data sources for this research are secondary and primary data, collected through literature and analyzed qualitatively. The results of the study indicate that the legal provisions regarding lease agreements made in the form of authentic deeds by notaries based on the applicable laws and regulations in Indonesia are stated in the Civil Code, specifically Article 1320 and Article 1548 to Article 1600, as well as Law No. 2 of 2014 concerning the Position of Notaries. The obligations and responsibilities of notaries in implementing legal provisions in the preparation of lease agreement deeds according to the UUJN include the obligation to ensure the fulfillment of the legal requirements of the agreement and the legality of the object of the agreement, upholding their position and authority as independent public officials. The legal impact of notary negligence in preparing lease agreement deeds that stipulate a period exceeding the validity period of management rights is very significant for the validity of the deed, legal certainty and protection of the rights of the parties. Therefore, the researcher recommends strengthening the principle of notarial prudence through strict verification of land documents, improving guidelines and supervision by the Supervisory Board, and developing further empirical research to improve notarial regulations and practices.148 PagesTesis Magiste

    Corn (Zea mays L.) is the second most important food source for humans after rice. Lodging is a significant problem for several crops, including corn, because it causes a decrease in yield. The height of corn plants can affect the level of lodging. This study aims to determine the effect of colchicine administration on the phenotypic appearance of corn variety NK 212. This study was conducted on Jalan Sp. Jerman, Saentis, Kec. Percut Sei Tuan, Deli Serdang Regency, North Sumatra Province, at an altitude of ± 25 meters above sea level from April 2025 to July 2025. This study used a factorial randomized block design (RAK) with 2 treatment factors and 3 replicates. The first factor was colchicine concentration (K): K0 (0 ppm), K1 (400 ppm), K2 (600 ppm). The second factor is the duration of immersion (N): N1 (6 hours), N2 (12 hours), N3 (18 hours). The parameters observed in this study included plant height, stem circumference, flowering age, leaf area, stomatal density, cob diameter, cob length, fresh cob weight, dry cob weight, number of seeds per row, and number of rows per cob. Based on the results of the study, colchicine concentration had a significant effect on plant height and stem circumference but no significant effect on other parameters. The control (K0) produced the highest plant height and largest stem circumference, while a concentration of 400 ppm (K1) produced the lowest plant height and smallest stem circumference. The duration of colchicine immersion had a very significant effect on plant height and stem circumference but no significant effect on other parameters. A 12-hour immersion (N2) resulted in the lowest plant height and smallest stem circumference. The interaction between a concentration of 400 ppm and an immersion duration of 18 hours resulted in the lowest plant height.63 PagesSkripsi Sarjan

    No full text
    Sensitivity analysis in DEA models using a fuzzy approach can provide significant benefits in measuring the environmental performance of housing. This method can help identify and measure the impact of changes in input and output data on efficiency scores, enabling more accurate and effective decision-making related to improving en vironmental management. The research methodology used quantitative methods with descriptive analysis and data efficiency using DEA with a fuzzy approach using out put orientation, which aims to measure and assess the level of housing environmental performance efficiency objectively and realistically, considering the high uncertainty of the data. The data used is secondary data related to indicators related to housing environmental sustainability. The results show that of the four Decision Making Units (DMUs) studied, without using the fuzzy approach, only Helvetia Housing achieved 100% efficiency. Meanwhile, Tuntungan, Martubung, and Johor Housing had effi ciency values of approximately 85.92%, 88.69%, and 94.87%, respectively. When the fuzzy approach was applied, the efficiency of Johor and Helvetia Housing remained at 100%, while Tuntungan and Martubung Housing experienced a decrease in efficiency to 78.22%, indicating a significant level of inefficiency. The results of the sensitivity analysis using a for Helvetia and Johor Housing were stable. Meanwhile, martubung and tuntungan experienced a decline in line with the high level of data certainty. This inefficiency was caused by excessive use of drainage inputs, indicating that the housing complex was not yet able to produce environmental outputs commensurate with the inputs used68 PagesTesis Magiste

    Comparison of Immunohistochemistry (IHC) Expression Before and After Chemotherapy in Breast Cancer Patients at H Adam Malik General Hospital, Medan

    No full text
    Introduction: Breast cancer is the most common malignancy among women in Indonesia, often diagnosed at advanced stages. Immunohistochemistry (IHC) markers—estrogen receptor (ER), progesterone receptor (PR), HER2, and Ki 67—are critical for molecular subtype classification, treatment planning, and prognosis. Chemotherapy may alter these biomarkers, warranting comparative evaluation before and after treatment. Methods: This retrospective cohort study analyzed 31 breast cancer patients at H. Adam Malik General Hospital, Medan, who underwent chemotherapy from January 2023 to January 2025. Data from medical records and paraffin blocks were used to assess ER, PR, HER2, and Ki-67 expression pre- and post chemotherapy. Statistical analysis employed Chi-square or Fisher’s exact test. Results: Mean patient age was 53.68 years; most had invasive ductal carcinoma (83.9%), grade 3 tumors (48.4%), and stage III disease (90.3%). The most common chemotherapy regimen was EC + 5FU (29.03%). Post-chemotherapy, ER decreased in 61.3% of patients, PR in 61.3%, HER2 in 71%, while Ki-67 increased in 77.4% (all p<0.001). Molecular subtype changes were significant (p=0.031), with triple-negative breast cancer (TNBC) increasing to 61.3% after therapy. Discussion: Findings suggest chemotherapy can induce substantial molecular changes via clonal selection, gene regulation shifts, and microenvironmental effects. Loss of ER/PR and HER2 may reduce responsiveness to targeted or hormonal therapies, while Ki-67 elevation indicates possible tumor repopulation. Conclusion: Significant alterations in IHC profiles and molecular subtypes occur after chemotherapy in breast cancer patients. Reassessment of biomarkers post therapy is essential for optimizing subsequent treatment strategies.

    No full text
    The crime of rape continues to increase and requires strong evidence in the law enforcement process. Developments in forensic science, such as DNA (Deoxyribo Nucleic Acid) testing, can assist in evidentiary processes due to their high level of accuracy. However, the implementation of DNA test results in the investigation of rape cases still faces juridical and technical challenges. This study examines the legal regulation regarding the use of DNA test results in criminal investigations under positive law in Indonesia, the mechanism for collecting and requesting DNA examinations in criminal investigations, and the implementation, obstacles, and efforts to address these challenges in the investigation of rape cases within the jurisdiction of the North Sumatra Regional Police. The research method used in this study is normative legal research employing statutory, conceptual, and analytical approaches. The data used consist of secondary data supported by primary data. Secondary data were obtained through literature studies, while primary data were obtained through interviews with officers of the North Sumatra Regional Police. The results of this study indicate that the use of DNA testing in criminal investigations in Indonesia already has a legal basis, although it is not explicitly regulated in the Criminal Procedure Code (KUHAP). Nevertheless, DNA test results may be classified as documentary evidence or expert testimony. Their legal standing is strengthened through Law Number 20 of 2025, Law Number 2 of 2002, Regulation of the Chief of Police Number 8 of 2018, Regulation of the Chief of Police Number 10 of 2009, Regulation of the Chief of Police Number 12 of 2011, and Regulation of the Chief of Police Number 6 of 2019. The process of collecting and examining DNA samples is conducted in accordance with forensic procedures as regulated in Regulation of the Chief of Police Number 10 of 2009. In practice, particularly in rape cases within North Sumatra Regional Police, DNA testing has proven effective in uncovering material truth, although internal and external obstacles remain. These challenges are addressed through improvements in facilities, human resources, inter-agency coordination, and persuasive approaches.171 PagesSkripsi Sarjan

    Relationship Between Liver Fibrosis Index (FIB-4) and the Incidence of Atrial Fibrillation Among HFrEF Patients in Adam Malik General Hospital, Medan

    No full text
    Introduction: Liver fibrosis, which results from chronic congestion in heart failure, indicates a systemic inflammatory response that may lead to atrial remodeling and atrial fibrillation (AF). The Fibrosis-4 (FIB-4) index is a non-invasive tool for assessing hepatic fibrosis. It could serve as a valuable predictor for AF in patients with heart failure with reduced ejection fraction (HFrEF), offering a practical approach for early risk stratification. This study aims to explore the relationship between the FIB-4 score and the incidence of AF in HFrEF patients hospitalized at Adam Malik General Hospital, Medan, providing valuable insights to inform clinical practice and improve patient outcomes Methods: We conducted a retrospective cross-sectional study involving 130 HFrEF patients. FIB-4 scores were computed using age, AST, ALT, and platelet count, while AF was diagnosed via electrocardiogram. We utilized chi-square tests and multivariate logistic regression to analyze the relationship between fibrosis grade and AF occurrence. Results: The average age of participants was 59 years, with males constituting 56.2%. AF was present in 65 patients (50%). The mean FIB-4 score was 2.49, with 22.3% exhibiting low fibrosis, 42.3% moderate fibrosis, and 35.4% high fibrosis. A significant association was found between FIB-4 fibrosis grade and AF (p=0.002). Patients with moderate fibrosis had a 4.951-fold increased risk (OR 4.951; 95% CI 1.742–14.073; p=0.003), while those with high fibrosis had a 5.649-fold increased risk (OR 5.649; 95% CI 1.936–16.483; p=0.002) compared to low fibrosis patients. Conclusion: The FIB-4 score significantly correlates with AF occurrence in HFrEF patients, although further prospective studies are needed to establish causality. Its potential as a simple, cost-effective, and non-invasive screening tool for identifying those at higher risk for AF warrants consideration in clinical practice.110 PagesTesis Magiste
