Abstract

Isotonic drinks made from coconut water are products that are widely liked, but there are not many flavor variants, so it is necessary to look for alternative ingredients to add flavor variations, so we need mangosteen rind juice as one of the ingredients that can be used as a flavor enhancer. This research aims to determine the effect and best proportion of mangosteen peel juice on the chemical and organoleptic properties of coconut water. This research method is laboratory experimental which uses an experimental design: Completely Randomized Design (CRD) 1 Factor which consists of 4 levels, namely Sugar concentration: Mangosteen Peel P1 = 20% : 15%, P2 = 15% : 20%. P3 = 10%:25%, P4: = 5% : 30%, and this research was carried out in 3 repetitions. The parameters tested are chemical properties: pH test, Total Sugar test, Sodium test, and Potassium test as well as organoleptic properties consisting of: taste, aroma, color. The research results show that the use of 30% mangosteen peel extract has chemical characteristics. Meanwhile, the best in terms of physical characteristics and organoleptics is the use of 20% mangosteen peel juice. The use of mangosteen peel juice increases potassium and sodium levels and also increases the chemical properties. This shows that mangosteen peel juice has great potential as an additional ingredient in isotonic drinks.

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.

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

Chicken meat is a source of animal protein that can be processed into various food products, including jerky, offering a more economical alternative without compromising taste and quality, although it has the drawback of less appealing color. This study aims to determine the optimal concentration of angkak (Monascus purpureus) as a safe natural colorant to enhance the color of minced chicken jerky and evaluate the effects of angkak concentration and oven temperature on its physicochemical properties, total plate count (TPC), and organoleptic characteristics. The study used a Completely Randomized Design (CRD) with four treatments combining angkak concentrations (1% and 3%) and oven temperatures (80°C and 100°C), each replicated three times. The analyzed parameters included color (L, a, b), moisture content, protein content, TPC, and organoleptic properties (taste, color, aroma, texture). The results of the study showed that adding angkak significantly increased red color intensity and antibacterial activity, while oven temperature affected moisture and protein contents. The best treatment was found at 3% angkak concentration and 100°C oven temperature, yielding dark red color, protein content of 27.13–30.06%, TPC of 0.022 x 10⁵ CFU/g, and high organoleptic acceptance. Thus, angkak canibe usedtas asnatural colorant and preservativeKfor minced chicken jerky.
