Abstract

ABSTRACT This study aims to explore the influence of ylang-ylang essential oil (Cananga odorata) and virgin coconut oil (VCO) on antioxidant, antibacterial, and organoleptic properties in the production of hand body lotion. Ylang ylang oil is known for its various health benefits, including antioxidant and antibacterial properties, while VCO is increasingly popular as a functional food oil with anti-inflammatory and antimicrobial properties. The methods used include distillation to produce essential oil, followed by physical characteristic analysis and effectiveness testing. Lotion formulation was conducted with varying proportions of essential oil and VCO. Tests conducted include antioxidant testing using the DPPH method, bacterial testing to determine antibacterial effectiveness, and organoleptic testing to evaluate the fragrance and moisturizing properties of the lotion. The research results showed that lotion formulations with specific proportions of ylang-ylang essential oil and VCO produced significant antioxidant activity, with IC50 values indicating strong antioxidant potential. In addition, bacterial tests showed that the lotion was effective in reducing bacterial colony counts, meeting microbial contamination standards according to SNI. Organoleptic test results showed a positive preference from panelists for the fragrance and moisturizing properties of the lotion, with some samples receiving excellent ratings.Key words: Essential Oil, Ylang-Ylang Flower, Virgin Coconut Oil (VCO), Hand Body Lotion, Antioxidant, Antibacterial, and Organoleptic Testing.

Abstract

When carrying out a construction project activity, a construction management system is needed. ConstructionManagement includes management of project cost control (RAB), time (Schedule), human resources (HR),project occupational health safety management (SMK3L) and risk classification and control. Projectimplementation control must be carried out from the beginning of the work until the project work is completedso that construction management must be by the implementation. The results of the review of constructionmanagement planning for the construction of the NAPZA building were dominant in the implementation phase,especially in time control where the project construction process which was originally planned for 148 daysor approximately 22 weeks became 24 weeks. This resulted in the problem of processing time where the targetwas not achieved and resulted in delayed project work. Project implementation control must be carried outfrom the start of work until the project is declared complete so that during the project development processunwanted problems can be avoided. The construction management that will be applied to the NAPZA buildingcan make the project run well and according to the desired schedule.
