This study will discuss the use of the Complementary Filter method in hardware development that use gyroscope and accelerometer sensors, in order to see the ability of the sensor to read movement and assess how effective it is when used under movements with varying levels of aggressiveness. The complementary filter is a method that as the name suggests is to filter input data taken from the gyroscope and accelerometer sensors, this method is able to take data from both sensors and combine them into a single data that is more accurate by ignoring the shortcomings and using the advantages of each sensors The device that will be used is the MPU6050 GY521, this is a device that has both the two sensors on a single PCB so it is easier and more efficient to use, it has 3 axes meaning that this device can read motion in 3-dimensional space, the microcontroller used is a a variant of Arduino with an ATmega processor. After doing the test it was found that the use of the complementary filter method will greatly help the accuracy of the data because the filtered data contains very small noise with a significant difference when compared to raw data without using the filtering method, but because delay still can happens, wich cannot be helped by using this filtering method, this device can only be used with certain levels of movement

RETRIANI BANOBE Implementation of a Virtual Local Area Network (VLAN) to support data transactions between networks. Supervised by PETERUS KATEMBA Virtual Local Area Network (VLAN) is a network technology that can physically separate a network into several smaller network segments. This means that devices in one Virtual Local Area Network (VLAN) can only communicate with other devices in the same Virtual Local Area Network (VLAN) via a router. Virtual Local Area Network (VLAN) aims to reduce the amount of broadcast traffic for each subnet. Mikrotik is used to create a new Virtual Local Area Network (VLAN) and configure different inter-VLAN routing to communicate with each other. A switch is a network device that works at the data link layer of the OSI model. Each VLAN will have its own broadcast domain so that broadcast traffic will only be sent to the same Virtual Local Area Network (VLAN) device. Switches add Virtual Local Area Network (VLAN) tags to data frames passing through ports configured as trunk ports. Winbox provides a user-friendly interface for creating and managing Virtual Local Area Networks (VLANs) on a proxy and assigns IP addresses automatically to devices in VLAN by configuring the DHCP server on the proxy. The proposed network topology includes connected network devices with a trunking configuration to prevent data collisions, as well as assigning IP statistical addresses to each computer, aiming to improve network performance with a bandwidth of 100 Mbps.

Inventory management at the Pada Village Office in Lembata is currently still conducted manually using physical ledgers, which triggers data inaccuracies and the risk of document loss. This study aims to analyze, design, and develop an integrated web-based inventory information system using the Waterfall method. The system implements a real-time public complaint feature to strengthen asset management transparency and support the implementation of the Electronic-Based Government System (SPBE), enriched with a public infrastructure loan/rental module and an automatic fine control mechanism. The system was built using Native PHP and a MySQL database. Functional evaluation using Black Box Testing on 8 core test scenarios showed a 100% success rate (Pass) without any technical errors. Performance efficiency evaluation through Google Chrome Network Tools demonstrated optimal server response speed, with an overall average Page Load Time of 751 ms (under 1 second). Compatibility testing verified that the public interface is fully responsive and adaptive when accessed through both desktop and mobile browsers. The integration of these various features establishes the proposed system as a practical solution for realizing accountable village-level administrative digitalization.

Access to clean water is a vital necessity for communities, particularly in areas that rely on borehole wells as their primary water source. However, manually operating these pumps without an adequate monitoring system can lead to issues such as dry-running, energy waste, and pump damage caused by electrical current irregularities. This study aims to implement an Internet of Things (IoT)-based monitoring system for borehole pump water levels and electrical current using an ESP32 microcontroller. Unlike systems that focus solely on water availability, this study integrates water level monitoring (via an HC-SR04 sensor), electrical current monitoring (via an ACS712 sensor), and a low-water protection mechanism (using a float switch) into a unified system featuring real-time Telegram notifications. The research methodology encompasses a literature review, field observations, system design, hardware and software implementation, and functional testing of each system component. Test results demonstrate that the HC-SR04 sensor successfully detects water level changes, the ACS712 sensor accurately reads the pump's electrical current, and the system effectively triggers automatic protection via a relay when low water levels are detected. Additionally, the system activates a buzzer alarm and sends warning notifications to the user via Telegram. Functional testing confirms that all system components operate according to the design, offering a practical solution to enhance the safety and reliability of borehole pump operations through real-time remote monitoring.

This study aims to design and develop an Augmented Reality (AR) application as an interactive learning medium to introduce Lembata traditional clothing to students of SD Inpres Dulitukan. Through AR technology, traditional clothing objects are displayed in three-dimensional form that can be observed directly through digital devices, making the learning process more interesting, easier to understand, and not limited to conventional visual materials. In addition, the application is equipped with audio explanations regarding the meaning and characteristics of each traditional clothing, providing a more comprehensive and contextual learning experience. The research method used is the Multimedia Development Life Cycle (MDLC), which consists of data collection, analysis, design, media development, testing, and evaluation stages. This method was chosen because it is suitable for multimedia-based application development and allows the development process to be carried out systematically. The results of the study indicate that the developed Augmented Reality application runs well on Android devices and is capable of displaying Lembata traditional clothing objects in three-dimensional form along with automatic audio explanations. Based on the Black Box testing results, all application features functioned according to the design. In addition, the questionnaire results showed that students gave positive responses to the application because it was considered interesting, easy to use, and helpful in understanding the introduction to Lembata traditional clothing. Therefore, this application can be used as an interactive educational medium to support local cultural learning while also helping preserve regional cultural heritage through the application of modern technology.
