Abstract. This community service program aims to accelerate the digitalization of education in Pesisir Barat Regency, Lampung Province, through the implementation of Content Delivery Network (CDN) technology using Starlink services and the Learning Management System (LMS) Moodle. The 3T areas (frontier, outermost, and underdeveloped) in this region face infrastructure challenges that hinder stable and fast internet access, which is crucial to support technology-based learning processes. This program involves the installation of network devices, such as Starlink for stable internet access, gigabit switches, and the integration of the Moodle-based e-learning system. Additionally, intensive training is provided to teachers, administrators, and students on using Moodle as a digital learning platform and managing technology-based educational content. The program's success is measured through several parameters, including internet stability and speed, the improvement of digital skills among teachers and students, and the adoption and utilization rates of LMS Moodle in the learning process. Speed test results show a significant improvement. Survey results indicate a substantial impact on teachers' digital literacy. Based on questionnaires distributed to a total of 30 training participants, 60% (18 participants) reported being very satisfied with the alignment of the training materials with their needs. Regarding the delivery of the materials, 63.33% (19 participants) were very satisfied, 26.67% (8 participants) were satisfied, 6.66% (2 participants) were neutral, and 3.33% (1 participant) were very dissatisfied. Direct observation during the implementation showed that teachers could effectively utilize Moodle LMS to manage digital classes. They were trained to create and organize teaching materials, assign tasks, and monitor student progress. This evaluation also highlights the potential for replicating and sustaining the program in other schools within similar regions. Through this evaluation approach, the program is expected to have a tangible impact on improving the quality of learning, expanding digital access, and serving as a model for implementation in other 3T areas across Indonesia.

Abstract

Advances in computer network technology and increased use of Internet information have reduced IPv4 offerings. This requires a computer network protocol that can replace the role of IPv4 which is currently limited/loose. Also known as Internet Protocol Verses 6 (IPv6), it aims to improve on IPv4 and does not represent a fundamental change from IPv4. Features that are available in IPv4 are also available in IPv6, but features that do not work in IPv4 are available in IPv4. IPv6 is no longer used. A transition mechanism is required to forward IPv6 packets to an existing IPv4 network and vice versa. One of the available mechanisms is automatic tunneling (abbreviated as Tunneling). The EVE-NG simulator is used to implement and study the routing protocol (OSPFv3) on IPv6 networks. To check the results, use the traceroute, ping command. The Juniper platform is implemented in this small virtual network to test the OSPFv3 protocol on an IPv6 network. This research explains how to assign IPv6 addresses on Juniper routers and end devices as well as their configuration. The Internet protocol layer is responsible for receiving and sending data packets within the network. In the virtual environment simulation mode, Juniper packets are analyzed and packet forwarding via IPv6 on OSPFv3 is used to make decisions for protocols in the IPv6 environment that are faster, and more secure.

Abstract

Abstract Researchers believe that Positive Emotions can significantly influence the Impulse Buying variable because the more emotional a person is, the more emotional they are because they have no financial problems, get good religious and social studies, and have a happy family who no longer think about prices when shopping. Apart from that, researchers also have a second belief, namely that the Store Atmosphere variable is able to moderate these two variables. This research is quantitative research with an exploratory approach. The data collected in this research used a questionnaire method for 300 people who had incomes above 20 million. This data is called primary data. The data used and collected were analyzed with Smart PLS 4.0. The research results showed that the Positive Emotions variable had a positive relationship and a significant influence on Impulsive Buying and the Store Atmpaoshere variable could moderate the relationship between these two variables.

Abstract

Hydroponic is one of the solutions of gardening methods using water as a nutrition medium. Usually, maintaining hydroponic plant quality and water nutrients are done manually and require human efforts, such as the degree of acidity or wetness (pH), TDS (Total Dissolved Solids), and nutrient temperature. With the Internet of Things technology, we can automate hydroponic control by measuring the nutrients' TDS, pH, and temperature values and controlling water nutrition by pump nutrition needs for hydroponic plants. This research uses the NFT (Nutrient Film Technique) for the hydroponic system and uses lettuce as the nutrition parameter. The lettuce parameters are pH, TDS, and Water Temperature equal to the sensor we used in the proposed IoT system. The condition has 27 classifications, and we use this classification as a reference in decision-making, using the K-Nearest Neighbor (KNN) algorithm to activate the actuator. We improve the simultaneous actuator from previous research with specified intervals and duration to achieve ideal nutritional conditions. The other improvement is that we collect more data and more testing times. The accuracy was 91.2%, with k = 3. From the evaluation results, the accuracy of KNN is quite high and has an advantage, which has better accuracy than the other algorithms and can activate actuator simultaneously. We conclude that the hydroponic nutrient automation system using the Internet of Things method is ready for real planting use with this improvement.
