Gotong royong, or mutual cooperation, is a deeply rooted local cultural value in Indonesian society that plays a strategic role in strengthening social cohesion and promoting environmental consciousness. This study aims to explore and analyze the function of gotong royong in fostering social solidarity and raising community awareness of environmental sustainability through various communal activities. These activities include neighborhood cleaning, reforestation efforts, and participatory waste management, all of which require active involvement from community members. Using a qualitative descriptive method, the research was conducted through field observations and in-depth interviews with residents actively engaged in gotong royong practices. The findings reveal that gotong royong serves as a powerful social mechanism that encourages a sense of togetherness, mutual aid, and shared responsibility among community members. These interactions help to solidify social bonds and create a collective spirit that is vital for social resilience. In addition to reinforcing social relationships, the practice of gotong royong significantly contributes to enhancing environmental awareness. Communities become more proactive in maintaining cleanliness, preserving green spaces, planting trees, and managing waste sustainably. The study concludes that gotong royong is not merely a traditional cultural practice, but also an effective and relevant instrument for promoting social and environmental well-being in contemporary society. Its continued integration into community development programs could further strengthen both social solidarity and environmental stewardship, making it a vital component in sustainable development initiatives. Therefore, revitalizing and institutionalizing gotong royong is essential for fostering holistic and inclusive community growth.

Abandoned mining sites often experience a decline in soil fertility, which impacts soil quality and agricultural sustainability. This study aims to explore the potential of Pseudomonas fluorescens in rehabilitating limestone mining lands and enhancing the growth of Sengon (Falcataria moluccana) trees grown in polybag media. Sengon was selected as a pioneer species due to its resilience in degraded soils and its ability to improve soil structure. This study used an experimental design involving eight different treatments, which included the application of manure and varying concentrations of Pseudomonas fluorescens. Evaluations were conducted on the 25th and 50th days by measuring plant growth parameters such as plant height, root length, and key soil chemical properties, including pH, organic carbon, total nitrogen, total phosphorus, total potassium, and cation exchange capacity (CEC). The results showed that the application of 15 mL of Pseudomonas fluorescens on day 50 resulted in optimal plant growth, as indicated by an increase in plant height, root length, and soil quality improvement. The application of Pseudomonas fluorescens also enhanced soil pH, organic carbon, total nitrogen, and cation exchange capacity, all of which contributed to the improvement of soil fertility in the limestone mining land. This study provides evidence that Pseudomonas fluorescens can play a role in the rehabilitation of abandoned mining lands and improve the growth of Sengon trees, contributing to the recovery of degraded ecosystems.

Community Service (Kukerta) is a form of student community service that aims to apply knowledge, build social awareness, and encourage positive change in the surrounding environment. This article discusses the role of Kukerta Group 44 students from UIN Sultan Maulana Hasanuddin Banten in environmental conservation efforts and increasing educational awareness in Cibojong Village, Serang Regency. The majority of the population in Cibojong Village earn their living as farmers, but the agricultural produce obtained is generally only sufficient to meet daily needs, without guaranteeing long-term economic sustainability. Therefore, students educate the community through guidance from the BPP (Agricultural Extension Center), about learning to farm for the long term, and invite them to join the farming community. In addition, the community’s education level is relatively low, with most children only completing elementary school. Through a participatory approach and qualitative descriptive methods, students implement various programs such as planting productive trees, waste management education, and socialization of sustainable agriculture. In the field of education, students hold tutoring activities, motivational classes, and literacy for village children and adolescents. The results of the activity show that the active involvement of students has a positive impact on increasing public awareness of the importance of protecting the environment and continuing education. Kukerta is an effective means of building collaboration between universities and village communities to address local challenges sustainably.

This study aims to analyze the structure and composition of vegetation on the banks of the Ira River (Wae Ira), Negeri Kamarian, Kairatu District, West Seram Regency. Riparian vegetation plays an important role in maintaining the stability of river ecosystems, both in terms of ecological, hydrological, and biodiversity aspects. The method used in this study is a combination of the continuous strip sampling method and the line plot sampling method, which are applied to four levels of vegetation growth, namely seedlings, saplings, poles, and trees. The results of the analysis show that the vegetation structure in the study area is divided into four strata, with varying species compositions in each stratum. The dominant species found include Pulai (Alstonia scholaris), Pulaka (Cyrtosperma merkusii), Buah rao (Dracontomelon mangiferum), and Salam (Syzygium polyanthum). The highest Importance Value Index (INP) at the tree level is owned by Pulai (Alstonia scholaris) at 54,2. The highest vegetation density is at the seedling level with 52000 individuals/ha and the lowest at the tree level with 341 individuals/ha. The Shannon-Wiener diversity index (H') ranges from 1.87–2.65, indicating a moderate level of diversity. The results of this study indicate that the Ira River border area still has a relatively good vegetation structure and composition, although there are ecological pressures that cause dominance by certain species

This study aims to analyze land cover changes in Pariaman City in 2013, 2018, and 2024 using Landsat-8 imagery with the support of the Google Earth Engine (GEE) platform and the Classification and Regression Trees (CART) algorithm. Land cover change is a critical issue in Pariaman City, as population growth, infrastructure development, and economic activities have driven significant land conversion. The classification generated eight land cover classes representing the general condition of the area. The analysis revealed that rice fields were the dominant land cover in all three periods; however, they experienced a substantial decline, indicating land conversion, particularly into settlements and road networks. In addition, the area of mangrove forests and water bodies in coastal regions decreased, while plantation areas in the eastern and southern parts of the city increased. Conversely, river land cover remained the smallest category, with annual fluctuations. The identified change patterns included urban sprawl (expansion of settlements into suburban areas), the conversion of productive land into infrastructure, and coastal degradation due to human activities and natural factors. The accuracy assessment produced overall accuracy and a Kappa index above 80%, while validation using the Mapping Accuracy method through Google Earth showed per-class accuracy rates above 75%, categorized as very good. These findings indicate that the use of satellite imagery and the CART algorithm in GEE is effective for monitoring land cover dynamics while providing valuable insights for local governments in formulating sustainable development policies and managing coastal environments such as those in Pariaman City.

Natural resource management in Paccellekang Village, which includes rice paddies, plantations, and teak trees, remains suboptimal despite its significant potential, particularly the abundant wood waste. This wood waste largely originates from agricultural activities, plantations, and small-scale wood processing. Currently, this waste is often simply burned or dumped, potentially polluting the environment and causing air pollution. However, if managed properly, wood waste can be transformed into high-value products that can provide financial benefits to the community. This community service activity aims to empower farmer groups through training in processing wood waste into marketable products such as charcoal, liquid smoke, and wood flour. These products not only have economic value but are also useful in various sectors, for example, liquid smoke as a natural preservative, charcoal as an environmentally friendly fuel, and wood flour as an industrial raw material. The program implementation method uses a structured approach that includes initial observations to identify potential partners and needs, outreach to provide a comprehensive understanding of the program's objectives, and training in wood waste processing technology. Furthermore, intensive mentoring and evaluation of implementation results are provided to ensure program sustainability. The results demonstrated that the farmer group members understood the concept of productive wood waste management and demonstrated high enthusiasm for developing innovative products. This program successfully improved the community's skills in utilizing local resources while reducing the negative impact of waste on the environment. Thus, this activity contributed to increasing community income and supporting sustainable economic development in Paccellekang Village.

The transition of children from early childhood education to elementary school (SD) is a critical phase in their psychological and academic development. During this phase, children face significant challenges, including changes to a more structured learning environment and increasing academic demands. At SDN 055991 in Langkat Regency, this phenomenon is reflected in the difficulties experienced by some students, particularly with basic skills such as reading, writing, and arithmetic, as well as with socializing with peers. These difficulties can impact children's long-term academic and social development. This study aims to identify the key factors influencing children's learning readiness during this transition period, utilizing artificial intelligence (AI) technology. Specifically, this study uses Artificial Neural Networks (ANN) and Decision Trees as tools to analyze the data obtained. The use of this data-driven approach allows for a more in-depth analysis of the complex patterns and relationships between various variables that influence children's learning readiness, such as family factors, social environment, and students' basic skills. This study also references various previous studies demonstrating the effectiveness of backpropagation and Deep Learning algorithms in the context of education and student performance prediction. This approach is expected to provide more precise solutions for understanding children's learning readiness and provide a more accurate picture of the factors contributing to difficulties experienced by students in the transition to elementary school. The results of this study are expected to provide relevant recommendations for parents, educators, and education policymakers to support children's learning readiness and strengthen basic education policies that are adaptive to the needs of students in this digital era.

Agroforestry is also a form of sustainable agriculture model. Agroforestry systems are formed of three main components, namely forestry, agriculture, and livestock. The agrosilvopastura system is the combination of woody components (forestry) with agriculture (annuals) as well as livestock on the same land management unit. The priority order of the most important alternative options for sustainable agriculture includes strengthening farmer institutions, developing a cadre of farmers/farmer groups aware of sustainable agriculture, and increasing demonstration activities for sustainable agricultural technology. Financial analysis shows that all agroforestry systems are economically viable, and agrosilvopastura provides the most inputs compared to agrosilnikultur and silvopastura. Erosion that occurs on agroforestry land agroforestry, especially agrosilvoculture in the buffer zone of Southeast Aceh District is not harmful because it is smaller than the allowable erosion (<30.6 tons/ha/yr). The total biomass and carbon of stands in agroforestry systems with agrosilvopastura type of 103.17 and 46.74 tons per hectare, respectively, are similar to the total biomass and carbon of stands in mangrove forests. carbon in Rhizophora apiculata mangrove forest with a density of 463 trees per hectare, which were 169.46 (biomass) and 47.08 (carbon) tons per hectare, respectively. Agrosilvopastura systems can play a role in mitigating floods compared to monoculture farming systems for each hectare of land for every 1 hour of work.

The People’s Palm Oil Replanting Program (PSR) is a national policy aimed at improving the productivity of smallholder plantations through the replanting of aging and unproductive oil palm trees. This study reviews the implementation of PSR in Indonesia by analyzing ten scholarly articles through a literature study approach. The findings indicate that program effectiveness is significantly influenced by technical support such as training, mentoring, the application of Good Agricultural Practices (GAP), and strategic partnerships for harvest absorption. However, implementation faces several challenges, including limited human resources, damaged equipment, inadequate funding, prolonged replanting periods, weak coordination among stakeholders, and lack of policy dissemination. Local institutions such as cooperatives (KUD) and farmer groups (Gapoktan) play crucial roles in ensuring program sustainability and inclusiveness by acting as managers and conflict mediators. Although farmers are generally ready and actively participate, regulatory constraints—particularly the requirement of financial guarantors—remain a barrier. The study recommends strengthening local institutional capacity, enhancing stakeholder synergy, and simplifying financial schemes as strategic steps to improve the long-term effectiveness of the PSR program.

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.

Watershed management requires active community participation as a key actor in ensuring environmental sustainability. This study aims to analyze the forms, levels, and factors influencing community participation in the management of the Bone Bolango Watershed in Gorontalo Province. The method used is a descriptive qualitative approach supported by quantitative data from questionnaires distributed to 45 respondents. The results show that 75.6% of respondents are unaware of watershed programs, and only 24.4% have been involved in the planning stage. In the implementation stage, participation reaches 53.3%, mainly in reforestation and waste management activities. About 48.9% are aware of the evaluation process, but only 40% consider it transparent. Some community members (44.4%) perceive economic benefits, especially from planting productive trees. Educational activities are considered effective by 71.1% of respondents, although participation remains limited. The Bone Watershed Forum is viewed as strategic, yet community involvement needs to be strengthened. Enhancing local institutional capacity, transparency, and cross-sector collaboration is essential to improving sustainable community participation in watershed management.

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.

The impacts of mangrove forests for coastal areas include preventing coastal erosion, being a soil catalyst from seawater, fisheries habitat, providing a broad economic impact, a source of animal feed, preventing global warming, a source of income for fishermen, maintaining water and air quality, developing tourism areas, providing a source of firewood, developing science, and maintaining climate and weather.

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.
