Abstract

Dyes have played an important role in human life, therefore the production of dyes has continued to increase from the past until now. The use of synthetic chemical dyes has apparently caused various health and environmental problems, this is what has triggered the return to use of natural dyes. Through advances in science and technology, research related to the extraction of natural dyes in Indonesia was carried out until 31 scientific reports were found that studied this matter in the last ten years. Literature studies with secondary data have summarized the novelty of research related to the extraction of natural dyes from plants, where currently flower objects are of great interest for observational studies. Various types of flowers have potential pigments that can be converted into natural dyes. The maceration extraction method is still the choice for extracting plant bioactive substances. Recently a study on the extraction of dyes from fruit peel waste was also carried out. It is hoped that the development of information related to the extraction of natural dyes will have more opportunities to be applied in various aspects.

Abstract

Mulberry is one of the plants that grows well in Indonesia, and has been used to support daily economic activities. Mulberries are of interest to researchers as research objects, regarding the bioactivity of mulberry plants. Over the past decade, from 2013 to 2023, research has been carried out regarding mulberries in Indonesia, with the aim of extracting and analyzing the extract substances. Data from 12 local research journals is known regarding the use of mulberry roots, stems and leaves to be extracted and applied for compound identification purposes, a study of the extraction methods used, and the specific purpose of mulberry extract as a preservative, patch formulation material, as well as an antibacterial agent, preservative, and antioxidants. The mulberry extraction procedures used are the maceration method, wave-based extraction (microwave and ultrasonic) and water bath energy. Qualitative analysis testing of mulberry extract substances was carried out to determine the content of alkaloids, tannins and terpenoid compounds. Quantitative analysis testing of mulberry extract substances was carried out to measure antioxidant activity, anthocyanin levels, and the biological activity of mulberry extract substances.

Abstract

The abundance of flora in Indonesia is an advantage that Indonesia has, so it needs to be preserved to support the continuity of social life. Cemara udang is a conifer tree with a straight, sturdy trunk, with hanging branches and sharp green leaves which is also found in Indonesia, which borders the Indian Ocean. This species is conserved in Indonesia and is found in coastal areas, beaches and mangrove forests. Through this literature study, exploration of the empowerment of cemara udang plants is discussed. Cemara udang plants provide protection from potential adverse climates such as strong winds and soil protection. This plant also has medical benefits such as inflammation problems, digestive issues, and sore throats, and is anti-bacterial. This plant is known to have biactive compounds such as alkaloids, glycosides, saponins, flavonoids, tannins, steroids, phenolics and triterpenoids. This study also explores the potential for sustainability of cemara udang plants in Indonesia to make them more commercially efficient, as an advanced material whose potential has recently been discovered as nanoparticles for health, and as an adsorbent to overcome the problem of aquatic environments that contain a lot of residual dye.
