The church plays a crucial role in spreading Christian values and nurturing the growth of faith within its community. However, in the context of GPSI EFATA, there are several challenges in effectively conveying church information. These challenges include the unappealing presentation of physical congregation news, the accumulation of paper, and limited distribution of information. In order to address these issues, this research project utilizes the Design Thinking method to develop a smartphone-based application for congregational news. The Design Thinking method consists of five stages: empathy, definition, ideation, prototype, and testing. During the empathy stage, the needs of the congregation are identified, particularly the need for more accessible and engaging information. The ideation stage then generates a solution in the form of a smartphone application. This application includes various features such as notifications, prayer schedules, financial reports, photo galleries, and management profiles. A prototype of the application was developed to meet these needs and was subsequently tested using a questionnaire. The results of the testing indicated that the application had an easy-to-understand interface, adequate features, and received suggestions for improvement. Overall, this smartphone application offers a modern and efficient solution to the challenges of delivering information within churches. It enhances accessibility and improves the quality of communication with the congregation.

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.

Posyandu is expected to be able to detect any deviations in growth and development early and provide recommendations to immediately visit related health services. Stimulation recommendations are also given if the detection results show that there is dysfunction in growth and development, so that the dysfunction does not experience more severe disorders. Delays in growth and development in children that are detected early are very important and are part of the duties of posyandu cadres. There are several applications that can be accessed by the community at home, such as the "Nutritional Status Check", "Nutrition Calculator", and "PRIMAKU" applications, where these applications can be downloaded using a smartphone on the Google Playstore, these applications can be used to help parents monitor their children's growth and development while at home. 5 The Ministry of Health has launched the book Stimulation, Detection and Early Intervention of Growth and Development (SDIDTK) (Karima et al., 2021; N et al., 2019).
