Abstract

Bacterial infections, such as S. aureus and E. coli, remain a global health issue, particularly concerning bacterial resistance, which often leads to serious complications. One approach to address this problem is the development of Metal Organic Frameworks (MOFs), known for their high conductivity and antibacterial activity. Zn-based MOFs are known to possess strong antibacterial activity because Zn²⁺ ions can damage bacterial cell membranes, disrupt enzymatic processes, and induce oxidative stress. In comparison, Zr-based MOFs are well known for their excellent chemical stability and biocompatibility. In this study, hydrogels containing three types of MOFs-Zn-BDC, Zn-Fer, and Zr-BDC were developed. This research aims to synthesize and characterize alginate-gelatin hydrogels containing MOFs and evaluate their antibacterial activity. The results indicate that the modification of alginate-gelatin hydrogels with MOFs has been successfully synthesized, as evidenced by FTIR, XRD, and SEM-EDS analyses. The materials successfully produced include Hy/Zn-BDC, Hy/Zn-Fer, and Hy/Zr-BDC. Antibacterial activity testing shows that adding MOF into the hydrogel matrix significantly increases the inhibition against S. aureus and E. coli compared to the hydrogel without MOF. Among the three MOF variants, Hy/Zn-BDC showed the highest antibacterial activity, followed by Hy/Zn-Fer and Hy/Zr-BDC. Specifically, Hy/Zn-BDC inhibited S. aureus growth by 95% and E. coli by 100%, accompanied by the lowest effective inhibitory concentration values (2.0 mg/mL and 2.4 mg/mL, respectively). These results demonstrate the high effectiveness of Zn-based MOF in enhancing the antibacterial performance of the hydrogel as well as its potential development for wound dressing applications.

Abstract

The Chow Kit settlement in Kuala Lumpur, Malaysia, is characterized by a population of homeless and low-to-no-income residents. As such, this area frequently becomes a focus for social institutions implementing Community Service Responsibility (CSR) programs, particularly in the health domain. This CSR initiative represents a collaborative effort between USIM Malaysia (Faculty of Dentistry) and the Faculty of Pharmacy (IIK Bhakti Wiyata Kediri, Indonesia), focusing on educational interventions to prevent and reduce dental caries through the use of herbal mouthwash formulations. Dental caries has emerged as a prevalent oral health concern with a significant impact on overall health. The condition originates from the formation of Streptococcus mutans bacterial biofilms, which are typically exacerbated by excessive consumption of sugary foods and tobacco use. The community service methodology employed participatory counseling and educational approaches, utilizing purposive sampling techniques. Evaluation of the program demonstrated enhanced comprehension among the 22 participants, with mean pre-test scores of 57.39 improving to 79.09 post-intervention, reflecting a 21.7% increase. While some participants maintained baseline scores, 86.5% of attendees (19 individuals) achieved improvements exceeding 20 points. Sustainable monitoring and evaluation mechanisms remain essential, given that the participant cohort primarily consists of homeless individuals whose transient living circumstances often preclude consistent maintenance of personal oral hygiene practices.

Abstract

This study aims to analyze the effect of cooling media variations (air, water, and salt water) on the mechanical properties of AISI 1045 medium carbon steel welded using the Metal Inert Gas (MIG) method. The experimental method was used with steel specimens in the form of plates which were then tested for tensile strength in accordance with the ASTM E8 standard and tested for hardness. The results of the study show that cooling with air produces the highest tensile strength (35.59 Kgf/mm²) due to the formation of ductile pearlite and ferrite microstructures. Cooling with water produced moderate tensile strength (34.42 Kgf/mm²), while cooling with salt water produced the lowest tensile strength (22.34 Kgf/mm²) due to the formation of hard but brittle martensite. Conversely, the highest hardness value was obtained with saltwater cooling (386.20 HV in the HAZ), followed by water, and the lowest with air. In general, slow cooling increases ductility and tensile strength, while rapid cooling increases hardness but decreases ductility. These findings emphasize the importance of selecting the appropriate cooling medium according to application requirements, whether the emphasis is on tensile strength or material hardness.

Abstract

This research analyzes the forms of notary's civil liability for negligence in making authentic deeds and the forms of legal protection provided to notaries. The background of this research is the increasing number of cases of authority abuse by notaries resulting in losses to the parties and third parties, as well as the imbalance between the idealism of the notary position as an independent public official and the reality of practice in society. The research problems formulated are: (1) what are the forms of notary's civil liability in making authentic deeds; and (2) what are the forms of legal protection for notaries. The method used is normative juridical with a statutory approach examining the Indonesian Civil Code and the Notary Office Law, as well as a case approach analyzing the West Java High Court Decision Number 09/PDT/2017/PT.BDG and the Supreme Court Decision Number 3121 K/Pdt/2018. The results show that notary's civil liability stems from their attributive authority and is based on unlawful acts (Article 1365 of the Indonesian Civil Code), which may include joint and several liability for material and immaterial compensation, deed cancellation, payment of dwangsom, and degradation of authentic deed's evidentiary power to that of a private deed (Article 1869 of the Indonesian Civil Code). This liability is personal and ongoing, not expiring even when the notary's position ends. As a counterbalance, notaries receive legal protection through the right to refuse testimony, internal professional forums (Supervisory Assembly and Notary Honor Council), the right to refuse making deeds, treatment as expert witnesses in court, and cultural protection in the form of a legal culture that respects the independence of the notary position. The Indonesian legal system has created a balance between accountability and professional protection for notaries.
