Analysis of Legal Protection and Remedies Provided by the Indonesian Notary Association to Notaries Suspected of Committing Criminal Offenses Related to Deeds They Drafted (A Study in the Regional Board of North Sumatra)
No full textThe notary profession serves as a public official with a strategic role in Indonesia's legal system. Its authority is governed by Law Number 30 of 2004 in conjunction with Law Number 2 of 2014 concerning the Notary Position (UUJN), and it is also bound by the Notary Code of Ethics (KEN) established by the Indonesian Notary Association (INI). However, the increasing number of alleged criminal cases involving notaries in North Sumatra-such as falsification of statements in deeds-raises serious concerns regarding the effectiveness of legal protection provided by INI and the alignment between legal norms and their implementation in practice.
This study aims to analyze the application of the UUJN and the Code of Ethics to notaries suspected of criminal offenses and to evaluate both criminal and civil liability concerning the deeds they produce. It also investigates the extent of the role played by INI, particularly the Regional Board of North Sumatra, in providing assistance and legal protection to notaries.
Employing an empirical juridical approach and qualitative methods, this research combines literature studies of the Criminal Code (KUHP), Criminal Procedure Code (KUHAP), UUJN, and INI documents, with interviews involving six informants including INI board members, law enforcement officials, and members of the Notary Honorary Council (MKN).
The results reveal that the legal protection afforded by INI is not yet optimal in practice. A significant gap persists between the applicable legal norms and their actual implementation, exacerbated by limited resources, weak advocacy efforts, and ineffective coordination between INI, the Notary Honorary Council (MKN), and law enforcement agencies. Despite a strong legal foundation through the UUJN and the Code of Ethics, the role of INI in providing legal assistance, advocacy, and mediation remains insufficient. The study concludes that the synchronization between the UUJN, the Notary Code of Ethics, and INI's protective practices is still weak. Structural reform and enhanced organizational advocacy capacity are urgently needed to ensure legal certainty and justice for notaries.131 PagesTesis Magiste

No full textGarlic (Allium sativum L.) is an important horticultural crop in Indonesia, widely used as a culinary spice, medicinal ingredient, and cosmetic material. The high consumption level of garlic is not proportional to its domestic availability, leading to the need for continued imports. Garlic growth requires adequate nutrients, which can be supplied through fertilization, including the application of azolla liquid organic fertilizer and biosaka. This study was conducted on the experimental field of the Faculty of Agriculture, University of North Sumatra, Medan City, North Sumatra Province, at an altitude of approximately 25 meters above sea level, from December 2024 to March 2025. A factorial randomized block design was used, consisting of two factors with three replications. The first factor was the dosage of azolla liquid organic fertilizer at four levels: 0, 75, 150, and 225 mL/polybag. The second factor was the concentration of biosaka at four levels: 0, 1.33, 2.67, and 4.00 mL/L of water. The application of azolla liquid organic fertilizer significantly affected plant height and number of leaves at 3–10 weeks after planting, as well as bulb diameter, fresh bulb weight, and dry bulb weight, with the best results obtained at 225 mL per polybag. The application of biosaka significantly affected both fresh and dry bulb weights, with the highest values achieved at 4.00 mL/L of water. The interaction between azolla liquid organic fertilizer and biosaka treatments showed no significant effect on any of the observed parameters.109 PagesSkripsi Sarjan
The Effectiveness of Scaffolding Learning Strategies on Increasing Mathematics Self-Efficacy of Primary School Students
No full textSelf-efficacy is an important factor that influences success in learning mathematics from the primary school level.
