The Potential of Digital Signatures In Notarial Deeds to Establish Legal Certainty
No full textThe development of digital technology has encouraged the use of digital signatures as an alternative to conventional signatures. The application of digital signatures as instruments of authentication and verification for electronic documents has become a significant issue in realizing efficiency, speed, and legal certainty. Although several countries adopting both Common Law and Civil Law systems have implemented the concepts of cyber notary and electronic notary, Indonesia continues to face normative barriers in its implementation. The primary obstacle lies in the regulatory disharmony between the Notary Law (UUJN), which still requires physical presence and conventional signatures, and the Electronic Information and Transactions Law (UU ITE), which recognizes electronic signatures as valid evidence. This study aims to analyze the potential application of digital signatures in notarial deeds to realize legal certainty in Indonesia. The research method employed is normative juridical with a descriptive-analytical approach, utilizing secondary data consisting of primary. secondary, and tertiary legal materials. The findings indicate that digital signatures hold legal validity under the Electronic Information and Transactions Law (UU ITE) and its implementing regulations, provided they meet the requirements of authentication, integrity, and non-repudiation. However, their implementation in notarial deeds still encounters regulatory challenges, particularly because the Notary Law (UUJN) does not explicitly regulate the use of digital signatures, Harmonization between the UUJN, the UU ITE, and other related regulations is required, along with strengthening digital infrastructure and legal literacy among notaries and the public. Thus, digital signatures have the potential to enhance efficiency, security, and legal certainty in notarial deeds, in line with the advancement of the digital era.169 PagesTesis Magiste

Automatic Goat Milk Filling System with UV Sterilization Feature Based On Omron CP1E Programmable Logic Control (PLC)
No full textGoat milk is a natural food product classified as a perishable commodity with a high
susceptibility to microbial contamination, including Coliform and Escherichia coli
bacteria. In many traditional farms, milk processing is still carried out manually—
from milking and filling to packaging—which increases the risk of contamination and
reduces milk quality. This study aims to design an automated system, compare its
performance with manual methods, and analyze the effective UV sterilization time for
goat milk. The system was developed using several key components, including a
flowmeter, capacitive proximity sensor, conveyor motor, DC pump, solenoid valve,
LED indicators, and a PLC module as the main controller. The test results indicate
that the capacitive proximity sensor operates effectively at a distance of 0.5–1.5 cm,
while the conveyor achieves an average speed of 0.0542 m/s along a 0.62 m track.
The flowmeter is capable of measuring an average volume of 331.6 mL within 4.056
seconds, corresponding to a flow rate of 4.91 L/min and an operating frequency of
48.08 Hz, with a standard deviation of 3.51 mL. Meanwhile, the manual system
achieves average filling volumes of 286.67 mL, 300 mL, and 308.33 mL, with standard
deviations of 30.54 mL, 30 mL, and 30.15 mL, respectively. The UV sterilization
feature demonstrates high effectiveness, reducing bacterial counts from 3.1–3.2×10⁶
CFU/mL to 5–6×10¹ CFU/mL after 3 minutes of exposure, achieving an inactivation
rate of more than 99.9%. Thus, the proposed system is proven to be feasible and
effective, with strong potential to improve hygiene, accuracy, and efficiency in small-
to medium-scale goat milk processing.106 PagesSkripsi Sarjan
