In this study daily rainfall data, the beginning of the rainy season data is obtained by calculating daily rainfall data using the Liebmann method. The best ARIMA model (3,1,0) with the equation y = 0,3162−1 + 0,1284−2−0,188−3 + 0,7434−4−0,934 is used for July, August and DMI data in August are considered as input and prediction error value ARIMA as a target. The beginning of the rainy season prediction results based on ARIMA, the results of testing and evaluation obtained values ​​of r = 0.14 and RMSE = 32.53.

Abstract

Elementary education plays an important role in shaping children's self-confidence and logical thinking skills, especially in the increasingly complex digital era. However, many children have difficulty in developing these aspects due to the lack of appropriate stimulation. The purpose of this community service activity is to provide socialization and assistance to 6th grade elementary school students in increasing their self-confidence and logical thinking skills. This activity is carried out through interactive methods, exploration-based, and persuasive approaches. This activity involves teachers, as well as educational facilitators in the form of training, educational games, and discussion sessions. The results of the community service show that this approach has a positive impact on children's cognitive and social development. Children who participate in this program experience increased courage in communicating and are better able to solve problems independently. This activity can be an effective model in supporting elementary education in the digital era.

Abstract

Palm oil frond waste is a type of agricultural waste that is quite abundant in Pematang Gubernur Village, Muara Bangkahulu District, Bengkulu City. To date, this waste has not been optimally utilized and tends to be discarded, thus potentially polluting the environment. This community service activity aims to improve community knowledge and skills in processing palm oil frond waste into compost through hands-on training (learning by doing). The implementation method includes identifying partner needs, counseling, technical training in composting, practical assistance, as well as evaluation and follow-up. The results of the activity show an increase in community knowledge and skills in composting, the formation of compost products resulting from the training, the development of training modules, and the formation of community-based compost processing groups. This activity proves that utilizing palm oil frond waste can be an environmentally friendly solution while supporting community food security.
