There are several categories to detect and measure driver drowsiness such as physiological methods, subjective methods and behavioral methods. The most objective method for drowsiness detection is the physiological method. One of the physiological methods used is an electroencephalogram (EEG). In this research wavelet transform is used as a feature extraction and using support vector machine (SVM) as a classifier. We proposed an experiment of retrieval data which is designed by using modified-EAR and EEG signal. From the SVM training process, with the 5-fold cross validation, Quadratic kernel has the highest accuracy 84.5% then others. In testing Driving-2 process 7 respondents were detected as drowsiness class, and 3 respondents were detected as awake class. In the testing of Driving-3 process, 6 respondents were detected as drowsiness class, and 4 respondents were detected as awake class.

Garbage can be said as a leftover or wasted goods can couse big problems in the future if it not being managed properly, Naturally, household waste and other types of waste have different decomposition times, and there is even waste that can be categorized as non-biodegradable by nature. Waste that is managed wisely by using the principles of Reduce, Reuse, Replace and Recycling things that are considered wasted and not useful can still be something meaningful. The rapid rate of garbage accumulation can cause some disease, damaging the environment and nature, and cause unpleasant sights and odors. Education is an action that given to the community so they have the knowledge and care to protect the environment. In educating the community, it is also necessary to be motivated so that the community has enthusiasm and passion. The education that has been given to the community of Sukajadi Subdistrict, Bandung, has caused the participants' knowledge to increase by 24%. The continuation of the education that has been given is education on how to coordinate sorted waste so that it can be a blessing and can be something that can be used in different functions.

During the pandemic of Corona Virus Disease 2019 (COVID-19) that hit Indonesia, all activities were very limited. Electrical Engineering Study Program of Universitas Kristen Maranatha was motivated to share knowledge especially in the field of science about "Basic Unity and Virtual Reality (VR)" to the public. This has been realized through community service activities pursued by students and lecturers. VR refers to computer simulations that create images of the world that appear in human senses, in the same way as humans perceive the real world in reality. This community service used the Participatory Action Research (PAR) approach. From the results of a survey of community service activities that have been carried out, it is concluded that the success in providing mentoring to improve the ability of the community to use Basic Unity and VR online, is shown by the results of an increase in the score from an average of 5.85 before the activity, to 7.58 (from a total score of 10) after the activity. The community service committee team's service during the activity was also considered very good and worthy of being maintained in subsequent activities. Meanwhile, the implementation of providing teaching materials, the readiness of the trainers, and the implementation of organizing activities online, still need to be re-evaluated and improved in the future for better results.

Farmers in Sumbersari village, located in Bandung district, were in great need of assistance in effectively managing their paddy fields to ensure the production of high quality and high yield rice. One crucial factor that significantly impacts it is the proper application of urea fertilizer based on the conditions of the paddy plants, which can be determined by measuring the chlorophyll content present in the leaves of paddy plants. Therefore, mentoring and literacy activities were held to educate farmers on the utilization of a chlorophyll content measuring device which is the result of research previously conducted by the Faculty of Engineering, Universitas Kristen Maranatha so that farmers are able to measure the precise amount of fertilizer that must be applied in accordance to the needs of their paddy plants. The mentoring methods covered socialization, demonstration, and hand-on practice with the measuring device. As the result, all farmers became proficient in using the measuring device that had previously been developed. The device’s size and weight are appropriately designed making it convenient for farmers to carry the device the fields and measure the chlorophyll content in the leaves of paddy plants.
