The challenges of practicum learning for the vocational institute are increasingly prominent. Innovation is needed to utilize technology and learning media to support distance learning and adaptive learning. Phytochemistry Practicum, a course given in the third semester of the Pharmaceutical and Food Analysis Department of Poltekkes Kemenkes Jakarta II, provides knowledge and skills to analyze chemical compounds in plants. This study aimed to develop interactive learning media for remote practicum of phytochemical screening materials at the Pharmaceutical and Food Analysis Department of Poltekkes Kemenkes Jakarta II. The methods used in this study were descriptive exploratory for laboratory experiment, multi-media development life cycle (MDLC) for AR development, and game development life cycle (GDLC) for building the gamification system. The augmented reality application and education game have been published in Playstore under the name AR Fitokimia and Virtual Lab Fitokimia. Both of these products were able to be accessed easily through mobile devices.

Honey is a highly nutritious food product and consumed by almost all the population in the world. It has a function as an antimicrobial. Staphylococcus aureus (S. aureus) is a common Gram-positive bacteria in food and Escherichia coli (E. coli) is a Gram-negative bacteria that often appears in environmental sanitation issues that both can cause infectious diseases.  Some infectious diseases can be treated with antimicrobials such as honey. The purpose of this study was to test the antimicrobial effects on honey products distributed in Pasar Minggu area. The antimicrobial effect test was performed in vitro using agar diffusion method by measuring the inhibition zone formed where the bacteria growth was inhibited by the presence of sample. The concentration of samples were 25%, 50%, 75%, and 100% (not diluted) and as aquades control. The results showed that honey tested with various dilution concentrations resulted inhibition zone and. The higher concentration of the inhibited zone zone showed antimicrobial activity against S. aureus and E. coli.

<p class="Abstrak"><strong>Abstract:</strong> Augmented Reality (AR) in the study of phytochemical screening is a technology that combines observation of experimental results in phytochemical screening as virtual objects with real environments. This study aimed to develop interactive learning media for phytochemical screening materials in the Phytochemistry Practicum at the Pharmaceutical and Food Analysis Department of Poltekkes Kemenkes Jakarta II. This interactive learning media application using AR technology was applied to iOS-based smartphones and designed for phytochemistry learning in the laboratory. The methods used in this study were descriptive exploratory for phytochemistry analysis and Multi-Media Development Life Cycled (MDLC) for AR development. 3D objects were resulting from phytochemical screening of Simplicia powder studied by using blender application, with Unity as a game engine and Vuforia as a library. The development of AR technology resulted in iOS-based mobile application named AR Fitokimia that visualized the phytochemical screening results. The application would help improve students' understanding and participation in distance learning. An interactive AR mobile learning application for iOS-based smartphones was designed for the entire class with an iFamily device in handling distance learning of phytochemical screening in the laboratory.</p><strong>Abstrak:</strong> Augmented Reality (AR) dalam kajian penapisan fitokimia merupakan teknologi yang menggabungkan pengamatan hasil eksperimen penapisan fitokimia sebagai objek virtual dengan lingkungan nyata.
