Submission of material that only uses printed books, printed pictures, and power points as well as limited infrastructure hinders student learning experiences. Augmented reality (AR) interactive media is one of the innovations to make it easier to guide material to make it more interesting and interactive. So this study aims to describe the feasibility of interactive multimedia augmented reality of food plants as a support for learning biodiversity in 10th grade of senior high school. The augmented reality system was created using Vuforia and Unity 3D software, and involved curriculum analysis, storyboard design, data collection, marker creation, and 2D object design of food plants, followed by AR media creation. This research used a quantitative descriptive method, data collection is carried out using validation instruments of material experts and media experts. Validators consist of 3 material experts and 3 media experts. The validation obtained an average total validation (RTVtk) of material experts at 3.83 and media experts at 3.80. This assessment is considered valid because it meets the validity standard, namely 3≤mRTVtk≤4. Thus, interactive multimedia augmented reality is suitable to be used as a learning medium in the sub-material of utilizing biodiversity as food plants in 10th grade of high school.

Food sovereignty has become a crucial problem for mankind. Sukabumi Regency is one of the regions that has been experienced a food crisis. The people of Nyangkewok Village, Sukabumi Regency have local knowledge in the use of food plants which can be an alternative in overcoming food insecurity. This research aimed to identify and describe the utilization of food plants by local knowledge of Sundanese Ethnic in Nyangkewok Hamlet, Sukabumi. The research was conducted in March-June 2019 with qualitative and qualitative methods, with data collection techniques by field observations and respondents interview. The results showed that there was a decline trend in the knowledge of using local food, in the lifestyle of the younger generation. Local knowledge tends to decrease from the older generation to the younger generation. There are 101 types of food plants that are utilized by local Sundanese people in Nyangkewok village with the dominant family type is Cucurbitae.

Butterfly is one of insect that comes from Lepidotera and has a very important role in maintaining ecosystem. Tangkahan is a Gunung Leuser National Park buffer zone that has been defined as a tourism area and make butterfly as one of tourism object. This study aims to identify and analyze the diversity of butterfly by active time (morning and afternoon) as well as the diversity of food plant and host plant in three types of buffer zones area. This research was conducted in December 2015 to February 2016 in Tangkahan, Gunung Leuser National Park buffer zone. The data was collected on three types of land cover that sattlement, river and forest.The observation of butterfly, food plant and host plant diversity were done using transect Pollard Method. Based on the study 5 family of butterflies were recorded with number of species as many as 61 species and 1.213 individuals. Food plants species were found as many as 48 species, while hosts plant were 27 species, and consisted of covercrop, sapling and poles. The highest of butterfly and food plant diversity index were recorded in the settlement for 3,43 and 2,75, the highest of host plant diversity index was recorded in the forest for 2,06.
