<![CDATA[The discourse on developing Kuala Bubon mangrove forest area in West Aceh as an ecotourism location has received a lot of sympathy and support among the community, considering that this forest has a high level of diversity of flora and fauna, one of which is bird species. In several ecotourism locations, birds attract tourists by enjoying various entertainment related to birds, such as bird watching, tours of bird habitats, and observing birds in the wild. The research was carried out in the Kuala Bubon mangrove forest, West Aceh, in September 2023. This research used a quantitative approach, calculating the level of diversity and mapping distribution based on bird location coordinates. The data collection method uses the point count and line transect method. Analysis of bird species diversity data using the Shannon-Wienner Diversity Index (H') formula was then carried out by mapping the coordinates of bird presence using the Quantum Gis software. The research results obtained 37 bird species from 22 families with a diversity index of 3.07 (high diversity), two species with the status of Near Threatened (Aegithina Viridissima) and Vulnerable Under (Acridotheres javanicus). Mapping bird species diversity with Quantum Gis provides opportunities for developing bird ecotourism, such as planning optimal bird-watching routes after knowing the distribution of bird species.]]>

<![CDATA[Conveyor is a transport system that can move objects from one point to another. This study aims to make a conveyor system based on mikrokontroller by testing several materials for the conveyor base, and testing the performance of the conveyor system. The microcontroller used is Arduino Uno. The sensor used is an infrared sensor, as a sensor for detecting objects on the conveyor. The research method used is an applied research method with experimental techniques. The first stage is to create a mechanical design for the conveyor, and the second is make an automation design. The results of the study show that the most effective material for the conveyor belt base is a 1.5 cm thick mattress material. The system test results show that the infrared sensor can be used to detect objects on the conveyor. When an object is detected, the conveyor stops for 0.5 seconds and is detected on the LCD monitor in the control box. The range of the infrared sensor is 15 cm – 50cm.]]>

<![CDATA[This study aims to examine the relationship between entrepreneurial orientation, entrepreneurial motivation, and perceptions of opportunities with entrepreneurship practices of Vacational High School students. The research method used is associative (relationship). This research was conducted on class XII students majoring in Accounting at Vacational High School 3 Padang. The number of samples in this study were 100 respondents. The sampling technique is saturated sampling, because the entire population in this study is used as a respondent. Data collection was obtained from the results of direct and online distribution of questionnaires to students. Data analysis in this study uses multiple linear regression analysis. The results showed that there was a positive and significant relationship between students' entrepreneurial orientation and their entrepreneurial practices. In addition, entrepreneurial motivation also has a positive influence on students' entrepreneurial practices. Perceptions of business opportunities are also positively correlated with students' entrepreneurial practices. This research provides evidence that the development of entrepreneurial orientation, entrepreneurial motivation, and perceptions of opportunities can encourage entrepreneurial practices in Vacational High School students. The results of this study have important implications for education in vocational high schools to strengthen student entrepreneurship learning and development. In addition, this study also underlines the need for attention to these factors in designing effective entrepreneurship programs in schools.]]>

<![CDATA[Technological developments present digital payment innovations for fast and practical transaction processes. Many digital wallets (e-wallet) services have emerged recently, becoming a trend in Indonesia. However, digital payments carry the risk of hacking user accounts, fraud (scams), phishing, and other criminal acts that aim to steal users' personal information. Financial is a sensitive issue; security is essential to digital payments. The research aims to analyze the effect of application security on user trust when making online transactions using digital payment applications. The study used a descriptive statistical method by distributing questionnaires to 50 Indonesians who have made electronic payments at least once for transactions. The study results show that application security significantly affects user trust in digital payments. Research results from various references show that application security influences impulse buying behavior and intentions to use e-wallet platforms.]]>

<![CDATA[Geometry is one of the subject matter in mathematics. Geometry has many type of shape, formula, area and volume. So there are many elementary school students feel no interest in studying geometry material because they feel difficult and don't understand it properly it is clear what each of these geometry looks like. To meet these demands, in line with developments in science and technology, the use of learning media is a solution. Increasingly diverse and interactive technology, one of which comes with utilizing AR technology. The use of augmented reality which is able to present 3D objects in visualizing geometric grids can make it easier to remember geometric shapes and utilizing this technology is able to create learning applications that stimulate students interest in learning to carry out learning activities actively and independently]]>

<![CDATA[The objective of this study is to create a water turbidity detection system, aiding customers of a municipal water supply company in preserving the quality of water for everyday use. The aim is to prevent the mingling of stored clean water with turbid water when the tap is turned on. To achieve this, we employ a smartphone as a remote control device, enabling users to monitor the water's condition remotely. The study's findings demonstrate that this system adeptly manages the water separation process based on its condition, allowing manual control via Bluetooth communication within a maximum range of 10 meters. This setup provides two control options: activating and deactivating the water channel through a solenoid valve. Test outcomes indicate the system effectively segregates the water as per its condition and promptly follows user directives.]]>

<![CDATA[Penggunaan teknologi Augmented Reality (AR) telah memberikan dampak positif dalam pengembangan aplikasi permainan, termasuk dalam permainan mengoleksi karakter. Namun, tantangan muncul terkait keamanan dan reproduksi yang mudah terhadap kartu AR yang digunakan sebagai kunci akses untuk memperoleh karakter. Untuk mengatasi masalah ini, penelitian ini mengusulkan perancangan aplikasi bernama Florateria yang memanfaatkan teknologi Near Field Communication (NFC) sebagai alternatif penggunaan Augmented Reality. Florateria bertujuan untuk memberikan pengalaman bermain yang lebih nyaman bagi pengguna dalam mengumpulkan dan merawat tanaman virtual. Aplikasi ini menggantikan kartu AR dengan NFC Tag. Setiap NFC Tag memiliki identifikasi unik yang terhubung dengan jenis tanaman tertentu. Pengguna dapat melakukan pemindaian NFC Tag menggunakan perangkat NFC yang terintegrasi dalam ponsel pintar mereka. Dalam pengembangan, metode DevOps diterapkan untuk memastikan kolaborasi antara tim pengembang dan operasi. Dengan menggabungkan teknologi NFC dan metodologi pengembangan DevOps, diharapkan dapat memberikan alternatif yang menarik dan aman dalam pengalaman bermain.]]>
