Abstract

Ta'aruf is one of the realms of social interaction which is the door to building a relationship between human beings in general. This has been discussed in the Qur'an which is a book that contains instructions for humans, that humans are created with different shapes or characters. The goal is for people to get to know each other. In other terms known as the term ta'aruf earlier. However, in this discussion the word ta'aruf is interpreted more specifically as an effort to recognize the opposite sex to be a life partner. So, ta'aruf is part of the initial stages before building a lasting relationship, namely marriage. Related to this, the law or sharia whose function is to fill the space for all community behavior, also follow these developments so that they can always provide explanations about new things that arise. The aim is to be able to provide legal certainty regarding a new lifestyle that is developing in society. This study uses the library method, namely by collecting as much data as possible from previous research and then concluding it into new research, it is intended that this research will later become one of the sources for similar discussions.

Abstract

Endophytic fungi produce bioactive metabolites that exhibit antibacterial, antioxidant, and anti-cancer activity. Rui (Harrisonia perforata (Blanco) Merr.) is a traditional medicinal plant proven to be an antibacterial and anticancer. Endophytic fungi live in plant tissues without damaging or producing chemicals that infect the host cell. Endophytes produce the same and similar compound as an original plant. This study aimed to isolate the endophytic fungi from Rui and determine their antibacterial, antioxidant, and cytotoxic activity. 13 fungal isolates were successfully isolated using PDA for seven days at 30°C. Molecular identification using the ITS1 and ITS4 DNA sequences only revealed six species: Diaporthe sp., Phomopsis sp., Aspergillus tubingensis, Aspergillus viridinutans, Pseudofusicoccum sp., and Daldinia eschscholtz. Seven isolates showed antibacterial activity based on plate assay. Aspergillus tubingensis and RA-1 exhibited antibacterial activity against Staphylococcus aureus and Salmonella typhi, with the MIC and MBC starting from 24 to 32 mg/ml. The DPPH assay showed the most increased antioxidant activity in Daldinia eschscholtzii with an IC50 of 98.14±2.39 µg/ml. The Brine Shrimp Lethality Test (BSLT) showed the highest potential cytotoxic activity, as shown by Aspergillus tubingensis and Phomopsis sp. with LC50 of 7.78±7.48 and 30.83±0.39 µg/ml. In conclusion, our study demonstrates that the fungal extract from Rui could be a source of antibacterial, antioxidant, and cytotoxic agents.

Abstract

This article discusses the condition of interfaith marriages in Indonesia after the emergence of SEMA No. 2 of 2023. Before the emergence of SEMA, interfaith marriage was something that was often debated by academics because there were no regulations that clearly regulated legal interfaith marriage. The emergence of SEMA is considered to provide legal certainty to support the implementation of Law no. 1 of 1974 so that marriage is based on the provisions of each religion. The SEMA is considered effective in closing the way for interfaith marriages, but its reach is limited to the judicial environment, while the reality in society is still happening even after the SEMA was established. This is because there is still a gap, namely through registration at the Disdukcapil Office. So it is considered necessary to harmonize norms in a number of laws and regulations such as the Marriage Law and the Administering Law. This research uses library research methods. Research data was obtained through literature study, namely reading and analyzing documents relevant to this research.

Abstract

Background: Eco-enzyme is the result of fermenting organic waste that possesses antibacterial properties. Objectives: This research aims to develop the best formula for an environmentally friendly antiseptic gel. Methods: The analysis carried out in this research includes testing the physical parameters and antibacterial activity of preparation. Results: The liquid eco-enzyme product produced has a distinct strong acid aroma with a pH of 3.1. Antiseptic gels were created in five formulations (F1-F5) by substituting the active alcohol ingredient traditionally used as an antibacterial agent. Test results showed that F1, F2, and F3 met all the requirements for the physical parameters of the gel, including pH (4.5-6.5), viscosity (2000-4000 Cp), spreadability (5-7 cm), and homogeneity (homogeneous). Meanwhile, F4 did not meet the physical parameter of viscosity, and F5 did not meet the parameters for viscosity and spreadability. Antiseptic gel made from eco-enzyme extracted from rambutan fruit peels exhibited higher antibacterial activity against S. aureus and E. coli bacteria compared to two commercial antiseptic gels and F1, which served as the negative control. Conclusion: An antiseptic gel preparation containing rambutan peel eco-enzyme with a concentration of 50% and 50% alcohol (F3) is the best formula.
