Abstract

Microplastics have contaminated almost all living ecosystems, especially in aquatic ecosystems. microplastics can interfere with the growth of marine organisms, and the impact is quite serious. This study aims to determine the shape and color of microplastics, the prevalence (presence) of microplastics and the intensity (amount) of microplastics in the digestive tract organs (Anadara granosa). The research was conducted during September - October 2024, sampling was carried out in the estuary area of Jono Beach, Lalang Village, Batu Bara Regency, North Sumatra, 40 samples were taken each. Microplastic extraction was carried out by taking the clam's digestive tract, weighing it into a microtube and adding 10% KOH solution as much as 3: 1 with the weight of the tissue, closed and allowed to stand for 24 hours at 40°C. After 24 hours in the centrifuge for 2 minutes at 500 rpm to precipitate all particles dissolved in the liquid. The solution on top was discarded and the solids on the bottom were taken for examination under a microscope. The results showed that microplastics were found in the digestive tract of clams in the types of fragments (80%), fibers (17%) and films (3%). While the most dominant color of microplastics is black (74%), red (14%), blue (6%), clear (6%), and clear (6%).

Abstract

The Qur'an is a holy book that was revealed with a very distinctive structure, not only in terms of language, but also in the arrangement of its verses and chapters. One important approach in understanding this structure is the science of munāsabah, which is the science that studies the relationship and interconnectedness between verses or chapters in the Qur'an. This article aims to examine the urgency of munāsabah in revealing the wisdom behind the arrangement of the verses of the Qur'an and its contribution to enriching the understanding of interpretation. The results of the study show that munāsabah not only plays a role in beautifying the narrative of the Qur'an, but also uncovers deeper meanings, including moral, legal, and spiritual messages hidden in the sequence of revelation. Awareness of the importance of munāsabah can encourage a more contextual and integrative approach to interpretation in contemporary Qur'anic studies.

Abstract

Kombucha is a fermented beverage that has been gaining popularity due to its health benefits, such as its antioxidant and probiotic content. One of the main ingredients in making kombucha is tea, and the type of tea used significantly affects the quality of the final product. This study aimed to determine the effect of using black tea on the growth of SCOBY (Symbiotic Culture of Bacteria and Yeast) and the organoleptic quality of kombucha. The research was conducted experimentally at the Microbiology Laboratory of Universitas Negeri Medan in April–May 2025. Kombucha was fermented for six days with a black tea solution to which sugar and a starter culture were added. The parameters observed included SCOBY growth (thickness and diameter) and organoleptic quality (taste, aroma, and color), which were assessed by ten panelists. The results showed an increase in SCOBY thickness from 0.5 cm to 0.8 cm and diameter from 12 cm to 15 cm. Organoleptic tests indicated that black tea kombucha tends to have a sour taste, a moderately strong aroma, and a yellowish-brown to brown color. Based on the research results, it can be concluded that black tea positively influences SCOBY growth and produces kombucha with good sensory quality that is acceptable to the panelists.
