Abstract

Recognition or identification is important to make it easier for us to recognize a type of plant or plant community. Each type has characteristics that have adapted to its habitat. Plants that exist in dry land areas including those around the University of Timor campus, it is necessary to identify or carry out scanning to identify names, characteristics and benefits and status in nature. Scanning is often done manually so that it is sometimes less effective and efficient familiar to the lay public. The aim of this research is to integrate scanning methods with optimizing ICT media such as using the “Sincatanesa” (Plant Scanning System) application with QR Code. The method used is a combination between observation methods and identifying specific tree growth forms and input into the “Sincatanesa” application which has been designed by researcher. Taxonomic data ranging from kingdom to species, habitus, benefits and IUCN status of each existing tree. Then make it QR Code attached to each tree. There were 18 types of trees identified and a QR Code was created for identification in the “Sincatanesa” application. The data stored is internet based so there will be a lot of data that can be stored, can be edited easily It's easy and just scan the barcode to identify the tree. Hopefully this application is known and used by all academic community at the University of Timor and the wider community. Furthermore, the “Sincatanesa” application can be developed based on smartphone so that it becomes more flexible and easier to use.

Abstract

The cultivation of cocoa plants in Berau Regency has been carried out traditionally with pre-conflict productivity of 700-800 kg/ha, but after the conflict and attacks PBK (Cocoa Fruit Borer) was reported to be only half. The yield quality is also low due to the pest attack and minimum post-harvest treatment. In addition, farmer institutions to be able to carry out activities in the garden together have not been well formed. According to Development Planning Agency at Sub-National Level of Berau Regency, in 2009 the area of cocoa plants in Berau Regency covered an area of 8,644 ha with a production of 2,362 tons. The area is spread across eight districts. With so many chocolate plantations in Berau regency, it certainly makes buyers or visitors, both from related ninas and individuals, become overwhelmed to find the location of chocolate plantations. Therefore, an application is needed to facilitate the search for location and data about the location you want to visit. Geographic Information Systems (GIS) or also known as Geographic Information Systems (GIS) have recently experienced significant developments along with the advancement of geographic information technology. GIS is a computer-based information system that combines map elements (geographical) and information about the map (attribute data) designed to obtain, process, manipulate, analyze, demonstrate and display special data to complete planning, processing and research problems. With the web-based designed GIS application, it is able to solve problems related to the vast chocolate plantation in Berau.

Abstract

East Kalimantan is a region with a high level of biodiversity, including endemic plant species such as Eusideroxylon zwageri (Ulin), Coelogyne pandurata (Black Orchid), and Nepenthes spp. (Pitcher Plant). Unfortunately, public awareness especially among young generations of the importance of conserving these local flora remains low due to the lack of engaging and contextual learning media. This study aims to develop an Augmented Reality (AR)-based educational media that visualizes interactive 3D models and descriptive information about East Kalimantan endemic plants. The research applies an interactive multimedia-based Research and Development (R&D) approach through stages of observation, documentation, 3D modeling, application development using Unity and Vuforia SDK, and testing involving students from local schools. Evaluation was conducted using pre-test and post-test designs, along with expert validation on content and usability. The results show that the developed AR application effectively enhances students’ understanding of local biodiversity and environmental awareness. This media also provides an innovative solution for digital conservation education that integrates technology with local ecological content.
