Indonesian achievements in the ASEAN Games continued to decline in achievement starting in 1962 with the acquisition of 51 medals and up to 2014 with the acquisition of 20 medals. The decline in achievement was due to the lack of athletic resources due to the absence of media that could record athletes' abilities in the field. Can record the athlete's performance before running, running and after running using the Heart Rate sensor and Motion Capture sensor. The results of the sensor recording will be stored in the database. This system applies the Internet of Things (IoT) concept, using raspberry pi, Arduino microcontroller, T34 polar heart rate sensor to capture and send heartbeat to receivers, gyro-based motion-capture sensors that named wear notch where this sensor serves to capture the movement of athletes, sensors communicate with the system using 4G connectivity, use MQTT as edge computing which acts as a communication medium from sensors to databases, Maria DB and influx DB as accumulation which plays a role in storing heart rate and athlete's movements that have been recorded by sensors, athlete performance monitoring platform with a heart rate sensor and athlete's motion capture is a web-based application that collaborates all processes from the sensor to the system. Sensor heart rate recording results are categorized good because the error margin is only 0.4%. Wearnotch sensor data can be stored in the database, and athletic data can be recorded before sports, while sports, and after sports in real-time

Vocabulary is an essential element in learning English which can help students to express their ideas both orally and in writing. However, students at Fakfak State Polytechnic still have limited vocabulary, especially technical English vocabulary. They are difficult to understand the operational terms in English. This study aims to determine whether the use of Readlang platform can improve technical English vocabulary mastery at Informatics Management students in Fakfak State Polytechnic. This research was conducted in one class and applied an experimental research using pretest and posttest group design. The results showed that the students’ mean score increased from 40.28 to 55.78. The hypothesis has been analyzed at a significant level of 0.05, and the results show that the t-value is 8.829 and the sig.2-tailed is 0.000. This means that the alternative hypothesis (Ha) is accepted and the null hypothesis (H0) is rejected, which means that Readlang platform can improve the students' technical English vocabulary. In addition, the questionnare results about students’ perception after using Readlang shows that the majority of students agreed that Readlang platform can increase the students’ enthusiasm in learning vocabulary (92%) and is also effective in helping to remember vocabulary (89.2%), and more importantly is easy to use (96 %).

Indonesia is a country that has a variety of regional languages. These diverse regional languages ??have their own challenges related to their preservation. One of the regional languages ??owned by Indonesia is Iha language, which is one of the native languages ??of Fakfak Regency, West Papua Province. Based on the current phenomenon, more and more people, especially the younger generations in the Fakfak Regency area, do not know and do not understand the Iha language. In practice, slang and borrowed languages ??from outside Fakfak are used more often than local languages. This has reduced the number of speakers and users of the Iha language, which has an impact on the erosion of local cultural wisdom in terms of language. One solution that can be done to increase interaction with regional languages ??is to present technological solutions that are familiar to the community. There is a fact that there is a high level of public interaction with the use of smartphones, so that it can be used as a means to recognize or learn Iha language by the younger generation or the Fakfak community in general. In this research, Fakfak regional language dictionary application (Iha language) was built, which was translated into Indonesian and vice versa. By using this application, the younger generations or people who want to learn the Iha language can find it easier to get the translation of the desired word. This application can also be used by users to learn the Iha language or to enrich their Iha vocabulary. Prototype is a method used by researchers to build this application and use Black Box method for testing. This research resulted in an application of the Iha – Indonesian and Indonesian – Iha language dictionary which in the test concluded that the application that was built is functioning properly.

Introduction: Heavy metal pollution is a serious environmental issue that can damage human health and ecosystems. The main sources of heavy metal pollution come from industrial activities and natural processes. Heavy metals such as lead (Pb), arsenic (As), and cadmium (Cd) have the potential to cause serious health problems in humans and flora and fauna. Purposed: To develop a water quality monitoring system based on electrochemical sensors and machine learning models to detect heavy metal concentrations in water in real-time. Research Methods: This includes sensor design, calibration, data collection, and training machine learning models such as logistic regression, decision tree, and artificial neural network (ANN). Results: Electrochemical sensors integrated with IoT technology were able to detect heavy metals with good accuracy. Testing was conducted at four different locations, and the highest lead (Pb) concentration was found in the C River (150.8 µg/L). The evaluation of machine learning models showed that ANN performed the best with the lowest MAE (2.5), followed by Decision Tree (2.8) and Logistic Regression (3.2). This system provides an efficient solution for real-time water quality monitoring and can be implemented in more sustainable water resource management. This study suggests further development of cloud-based monitoring systems and the use of more complex models like deep learning to improve system accuracy and flexibility.

The WW Candied Nutmeg MSME is a nutmeg processing business with significant growth potential; however, it faces challenges regarding production process efficiency, the implementation of Good Processed Food Production Practices (CPPOB), packaging, and product marketing. These issues impact production capacity, quality consistency, packaging appeal, and market competitiveness. This community service initiative aims to enhance the production efficiency and competitiveness of the WW Candied Nutmeg MSME through the application of appropriate technology and partner capacity building. Implementation methods included coordinating and identifying partner needs, designing and fabricating a hydraulic press, installing and providing training on the equipment, conducting CPPOB training, developing label and packaging designs, providing digital marketing training, and offering periodic mentoring and evaluation. The results demonstrate improved performance for the WW Candied Nutmeg MSME across production efficiency, business capacity, CPPOB practices, packaging, and marketing. The use of the hydraulic press reduced the time required to press 10 kg of nutmeg pulp from 120 minutes to 30 minutes (a 75% reduction) and doubled production capacity from 10 kg to 20 kg per two-week period (a 100% increase). Implementing CPPOB measures such as the use of personal protective equipment (PPE), polypropylene (PP) containers, and sealing machines improved hygiene practices and packaging process control. Design development using Canva was applied to full-print aluminum foil standing pouches and white plastic standing pouches featuring glossy vinyl sticker labels, allowing for a more structured presentation of product identity and information. Leveraging WhatsApp and Facebook Marketplace expanded marketing channels, resulting in a sales increase from 76 packs to 130–150 packs per two-week period (a rise of 71.1–97.4%). Overall, the integration of appropriate technology, CPPOB standards, packaging innovation, and digital marketing has strengthened the production and marketing readiness of the WW Candied Nutmeg MSME.
