Abstract

Green caviar (Caulerpa lentillifera J. Agardh) contains substances which potentially act as antioxidant. This research aim to determine the antioxidant activity of Green caviar extract using free radical scavenging method by 1,1-Diphenyl-2 Picrylhydrazil (Dpph). Green caviar was extracted with sequences extraction using n-hexane, ethyl acetate, and etanol 96% with the yield value for n-hexane, ethyl acetate, and ethanol are 2.256%, 4.176%, 5.548% respectively. Furthermore, the chemical contents of each extract were identified using phytochemical screening and TLC qualitative test with n-hexane : ethyl acetate ( 8 : 2 ) as mobile phase and silica gel 60 F254 as stationary phase. The results showed that each green caviar extract has antioxidant activity with IC50 value of n- hexane extract 61.057 μg/mL identified as moderate antioxidant (50-100 μg/mL) ethyl acetate extract 41.756 μg/mL included as strong antioxidant (10-50 μg/mL), and ethanol 96 % which is 52.116 μg/mL classified as moderate antioxidant (50-100 μg/mL). Ethyl acetate is the best solvent to be used to extracting the antioxidant compounds of Green caviar.

Community Service Program is a tangible expression of the student's obligation to perform one of the Tri Dharma of The College, which is in an aspect of devotion. Where this dedicated activity is carried out with the aim of solving problems and providing solutions to the real problems around people. Community Service Program is already underway in Ngaso Village, Ujung Batu Sub-District, Rokan Hulu Regency. The lack of awareness of people in the management of garbage is a major problem in the area, so it is a major concern for the ethics group. With these conditions, students are encouraged to develop programs that evisce "reuse" concepts on "Urban Farming" Urban Farming is an activity of raising crops by leveraging land with a finite method of verticulture. Where secondhand goods are used as containers for growing crops. The aim of the program is to exploit and reduce the amount of waste used bottles, to increase public awareness of the importance of preserving the environment, and to add aesthetic value to the target.

Abstract

Inclusive education requires facilities and infrastructure that support student diversity to ensure equal access to education for all. This research uses qualitative research with a case study research design. Qualitative research with a case study design is a form of qualitative research based on human understanding and behavior. This research uses data collection techniques using interviews, observation and documentation. The research results show that adequate facilities and infrastructure can create a safe, comfortable and conducive learning environment, can improve the quality of learning and develop various skills for student service in inclusive schools. This aims to support the development of each individual to create education that embraces student diversity.
