Community service activities were carried out in one day at SD GMIT Lamalu, Pantar District, Alor Regency. We were present to deliver material about LCM and LCM. During the community service, several students were interested in completing the material or questions given using factor trees. In the learning process about LCM and LCM, it can run well and can improve the quality of learning for students at SD GMIT Lamalu.

Clean living behavior can be done by maintaining the sustainability of life can be done by reducing waste, saving energy, planting trees, and not littering. Waste sorting can be done by separating organic and inorganic waste into different trash bins. In addition, inorganic waste can also be separated again based on its type, such as plastic, paper, glass, and metal. Facilitates the process of collecting and processing waste for recycling. The Principles of Clean and Healthy Living Behavior (PHBS) recommend the use of waste sorting methods. The daily habits that we do to maintain personal and environmental cleanliness consist of this behavior. . Along with the emergence of various diseases that often attack children aged 6-12 years, PHBS in schools is a collection of behaviors carried out by students, teachers, and school residents based on learning so that they are able to independently prevent disease, improve their health. Implementation of better waste sorting practices can reduce the negative impact of waste on the environment, increase the efficiency of waste management, and provide long-term benefits for school residents. Schools are one of the places that have great potential to educate students about good waste management. SD Negeri 2 Kelusa has problems related to the lack of student knowledge about waste sorting and utilization, especially organic waste. Most students at SD Negeri 2 Kelusa still have limited understanding of the types of waste and how to process it. Most students do not realize and understand that organic waste can be reused, so they tend to throw it away with other waste.

Land degradation due to intensive agricultural practices is a serious issue threatening food security and ecosystem balance. Monoculture farming systems often lead to soil fertility decline, increased erosion, and reduced soil biodiversity. As an alternative, agroforestry has been developed to enhance agricultural productivity without compromising soil health. Agroforestry integrates agricultural crops with trees or other woody plants in a mutually beneficial system. Several studies have shown that agroforestry improves soil organic matter content, retains soil moisture, and reduces erosion and nutrient loss. This study employs a literature review method to analyze the effectiveness of agroforestry in improving soil health and agricultural productivity. Agroforestry has been found to enhance agricultural productivity through crop diversification, efficient land use, and climate change mitigation. Diversification not only strengthens food security but also increases farmers’ income by minimizing crop failure risks and enhancing nutritional value. Additionally, agroforestry optimizes land use by improving yield per unit area and reducing environmental degradation through natural resource conservation. Agroforestry also plays a crucial role in mitigating climate change by increasing ecosystem resilience, sequestering carbon, and reducing extreme weather impacts. However, the adoption of agroforestry faces challenges, including a lack of farmers’ knowledge, limited policy support, and varying environmental conditions. Addressing these barriers through improved education, supportive policies, and sustainable resource management can accelerate agroforestry adoption. With broader implementation and strong policy support, agroforestry can drive agricultural sustainability and enhance community well-being.

One of the common pests found in oil palm is the nettle caterpillar (Setothosea asigna), which can consume between 300 to 500 cm² of leaves per individual. A single oil palm tree may host between 5 to 10 of these caterpillars. This study aimed to evaluate the effectiveness of fogging in controlling Setothosea asigna infestations on oil palm trees of varying heights at PT Socfindo, Matapao Estate, North Sumatra. The research was conducted in two plantation blocks with different tree heights: block 49 with trees ranging from 9–12 meters and block 46 with trees ranging from 3–6 meters. Data collection involved an initial census to count caterpillars before fogging, followed by a post-fogging census to observe mortality rates. Data were analyzed using a t-test to compare the effectiveness of fogging between tall and short trees. The results showed that fogging was more effective on shorter trees, with an average mortality rate of 94%, compared to 90% on taller trees.

Dreams can be considered as dated hopes. Therefore, everyone should possess them in order to have life goals and work towards turning those dreams into reality. Dreams are like trees that continually grow – the more they are nurtured, cared for, and protected, the stronger their roots become, the lusher their leaves, and the more abundant their fruits. This also applies to children. Often, adults perceive children's dreams as mere fantasies, yet there are also many adults who have successfully realized their childhood dreams. This signifies that the dreams they have can develop and bring about impacts that children can experience in their interests during the learning process (Styawan et al., n.d.). Almost the majority of participants do not yet grasp the significance of their dreams and the benefits they will feel in the future. This study aims to provide an understanding to students regarding the concept of dreams and the benefits that will experience improvement. This can be proven by the students' self-confidence in writing down the dreams they want to achieve through the dream tree that has been provided. Therefore, university students conducting the socialization of dreams and aspirations to elementary school students can provide them with the motivation and inspiration to strive towards their dreams, aspirations, and hopes for the future. The hope is that this socialization activity can have a positive impact on students by equipping them with self-confidence in the dreams they aspire to.
