Abstract

One of the learning management system learning is Edmodo. Edmodo was developed based on the principles of group-based classroom management and social media. E-learning is expected to be able to reduce obstacles in the implementation of teaching and learning activities that are no longer limited by distance and time. Teachers and students no longer need to come face to face and interact through the e-learning application. Edmodo learning media is used by students, teachers and parents to monitor their children's learning development. Students who use Edmodo can discuss with each other whenever and wherever subjects with other students related, increase the interaction of lecturers with students, they can be more independent in learning, and material that has been uploaded by lecturers can be downloaded by students and used as a learning reference source. In addition, assignments are given through the assignment and quiz features that have a time limit so that they can train discipline in doing the task. The service team empowered the teachers and students in the teaching and learning process using the e-learning system in the form of Edmodo training at Al-Ukhuwah Subang High School. How to cite:Cholis, N., Rhakasywi, D.

Abstract

In an effort to help improve the welfare of fishing communities, universities implement community service programs, this is an alternative in empowering the economy of fishing communities. There is a fishing village in Pulo Ampel Village, Serang Regency, Banten Province. Fishing activities by fishermen around the offshore Pangkalan Ikan in the village. Puloampel has a population of 11,758 people, namely 5,943 men and 5,815 women. Most of the people in Puloampel are fishermen, trading businesses, and farmers. The size of the existing fishing boats are generally relatively small, between 3 GT and 5 GT. The number of fishermen is 126 people, and there are 38 operating fishing boats. The fishermen use fishing boats generally leaving at night until the morning ± 8 hours. Currently, electricity needs for lights and other tools use batteries/batteries with electric shocks charging every 2 days. Complaints about charging the charger, the battery will be damaged quickly. To overcome and save electricity, it can be used as an electric charger with solar panels. Therefore, the community service team can provide counseling and training on the installation of solar panel electrical components (solar energy) for fishing boats owned by fishermen. The problem faced by partners (fishermen) who have been complaining about this is that the batteries used are damaged quickly, because the batteries are removed too often for charging electric shocks, this hampers the economic welfare of the fishermen's families because of additional costs. The purpose of implementing this community service program is to increase applied knowledge for small-size fishing boat electricity, and by utilizing solar/solar energy components applied to ships, it can reduce costs and extend the technical life of batteries/batteries.

Abstract

The addition of reflectors to solar panels is used to increase the intensity of sunlight received by solar panels so that the electrical power generated by the panels increases. In adding reflectors to solar panels, they must consider various factors to be able to increase the power generated without having a negative effect on solar panels , one of which is providing a cooling system. Therefore, research is needed to increase the power generated by solar panels and cooling systems that are suitable for overcoming rising temperatures due to the addition of reflectors. The study was conducted by varying the glass mirror reflector, aluminum foil reflector, angle of the reflector, and heatsink-fan cooling system. The research method used in this study was to compare 2 solar panel models, namely: solar panels with the addition of glass mirror reflectors / aluminum foil and heatsink-fan cooling systems, and solar panel models without any addition. The results show that the solar panel model with the addition of a glass mirror reflector / aluminum foil can increase the output power according to the angle of the reflector, the highest increase reaching 16.70% in the 450-angled aluminum foil mirror reflector. The heatsink cooling system is considered to be useful for reducing the temperature of solar panels, but the decrease is relatively small below 5%.

Abstract

In an ef ort to improve the welfare of fishing communities, the Community Service program is an alternative inempowering the economy of fishing communities. There is a fishing village in Puloampel Village, Serang Regencycarrying out fishing activities around the of shore area of Pangkalan Ikan. The livelihoods of the people inPuloampel Village are fishermen, traders and farmers. The fishing community has fishing boats, generally made ofwood, with a capacity of 3 GT to 5 GT, which rest at the Rukun Nelayan Cinta Bahari pier. The number of fishermenis 126, and the number of fishing boats operating is 38. When operating fishing boats, fishermen generally leave atnight until morning for ± 8 hours. The need for electric lighting so far has been to use batteries by recharging every2 (two) days, this has resulted in the batteries often being damaged in addition to the expensive cost of rechargingthe batteries. The aim of the Community Service activity is to implement solar power generation on fishing boats tosave battery costs. The method used is to provide counseling and training on installing solar cell panel componentson fishing boats. As a result of Community Service activities through outreach and training activities, fishingcommunity groups have been able to assemble/install and maintain solar cell panel components independently.Apart from that, the evaluation of fishing operation activities on 6 fishing boats for 6 months can reduce costs byIDR 22,140,000 so that this can provide prosperity and improve the economy for the fishing community.
