One of the most important things in the teaching and learning process is learning that is creative and fun because it can help students to succeed in learning. For a teacher, mastery and knowledge in utilizing technology is a competency that must be mastered in order to support the improvement of the learning process and the delivery of material to students. Facts on the ground show that Indonesian language teachers still use conventional learning method as well as the use of technology which is limited to using LCD media and laptops to convey material and give assignments. In addition, smartphones have not been used optimally as learning media. The purpose of this study was to determine students' perceptions of the use of Kahoot-based interactive learning media on learning outcomes. This research was total sampling basis are all number of the population are used as samples.  The samples of this research involves 30 people. Data collection used in this research is questionnaire. This study used a quantitative approach and data were analyzed using an independent sample t-test to determine the level of Kahoot application as an interactive learning media for Indonesian subjects in descriptive text material. The results showed that students tended to have very good perceptions of 46.67% regarding the use of Kahoot media in learning Indonesian. The benefit of this research is to provide additional knowledge and information to teachers, especially Indonesian language educators, in the use of Kahoot-based interactive learning media.

Students at SMA Negeri 1 Central Bengkulu are still dominated by the manual method, namely taking student absences by recording them on paper which will later be summarized from each student's attendance data. Because the manual recap of student attendance data also affects the information about attendance recaps which is still limited to the school, so parents/guardians cannot monitor student attendance levels. Inconsistency in attendance data can be detrimental to students, there is often a difference between the absences listed in the attendance register book/record into the system, which is one of the factors that makes the original data and data that have been verified into the system different. Utilizing the location of an Android smartphone to become an attendance system, which functions to provide location information based on the user's nearest location, assisting in searching for locations based on 6 existing parameters, namely education (high school/vocational school/university), hospital, hotel, restaurant, tourist attraction , and malls/traditional markets. It is hoped that this application will always be up to date so that this application follows developments in Android-based lecturer/teacher attendance information technology using the Flutter framework.

Most dairy farmers in our country still rely on human labor to monitor the condition of their farm areas. The current problem is the manual security system for barns, meaning that the barns need to be constantly checked around the area at all times. This is especially risky at night, when livestock theft is more likely to occur. This research implements PIR sensor technology to monitor movements around the barn, MC-38 magnetic sensors for gate security, and utilizes Android smartphones as devices to display barn data processing results, allowing real-time monitoring of barn security. The research is conducted using the Research and Development (R&D) method by Borg & Gall, encompassing only six steps. The results of the system evaluation by experts show a score of 3, falling between 2.1 – 3.0, categorized as Valid. User validation results show a score of 27.2, also falling between 2.1 – 3.0, categorized as Effective.

Mammals are animals with the characteristics of breastfeeding, sweating, and having four limbs such as four feet, a pair of feet and hands, or a pair of wings and feet. In some kindergartens, there is an obstacle where the school targets children from disadvantaged families so that carrying out activities outside the classroom which definitely requires a lot of funds will be difficult to carry out. As technology progresses, there is technology that can help children meet their learning needs and visualizations that are very interesting to use, such as Augmented Reality.The application of augmented reality was created to help children learn to recognize mammals without needing to do activities outside of school. The implementation is carried out using the marker based tracking method accompanied by design tools using UML. The program is made in the form of an Android smartphone application.The results of this application can show mammals in three-dimensional form that is close to their original form. This will help students recognize mammals in more detail, from those that are easy to find to those that are difficult to find or even dangerous to approach.

From this study, the automatic electric oil heater can be used to adjust the temperature value and the automatic electric heater will be able to turn off automatically according to the setpoint temperature value determined through a smartphone device or IoT program. Monitoring can also be done with the app, as well as being able to view temperature values directly through the LCD. This tool is in the form of an electric heater that will be used to heat ship fuel automatically and is more practical and efficient. It is also easier to maintain than a boiler on a ship. The design of this tool is based on accurate calculation of temperature values, with which the process of heating up fuel becomes faster. From the results of this study, a heat sensor that can read the temperature value and the buzzer will sound and the device will automatically turn off if the temperature has reached a specified setpoint. This research was carried out when the ship was about to make a departure to find out the temperature in the heating of the fuel on the ship. Testing Design of an automatic electric oil heater as a replacement for IoT-based thermal oil boiler on this bulk carrier ship, it can be known the disadvantages and advantages of this tool, testing can be done by putting oil into the electric heater, then in a short time the oil will heat up quickly, and the tool will be able to turn off automatically and the buzzer will immediately turn on when the heat has reached the specified temperature. In the temperature setting, it can be set in a smartphone or an app that can adjust the temperature and turn off the appliance from a considerable distance. However, the application must use the internet network and cannot be accessed locally, the use of IoT requires devices and smartphones to be connected to the internet.    

The business of selling coffee in the world is growing more easily and quickly with the provision of a place which is usually called a cafe or shop. One of them is the Titik Hitam Nalar cafe in Jakarta, but the ordering process with customers takes longer to wait for orders and customer payments that are not neatly arranged create conditions that’s are not conducive, resulting in continuous negative criticism. Therefore, an application is needed that helps employees work in every part, both in terms of ordering, manufacturing, and payments, using the FIFO algorithm which focuses on which services are prioritized first in order to reduce negative sentiment from customers. The Android-based application was created by involving every design phase, making it easier for customers and employees to provide a service facility that works well and is suitable for use.
