This research has the objective to determine the physical and social values of homegarden vegetation that influenced the reduction of SPM value on air, and the factors related to community attitudes and functions and existence of homegarden. Research results showed that SPM on air experienced a decline with increasing vegetation shade. Height of tree and LAI were negatively correlated with SPM values, meaning in an increase of LAI values and tree height would reduce the value of SPM. Tree height significantly effect (P-valeu=0.021<α) on reducing SPM by (y=920.4-59.66x) and LAI also has significantly effect (P-value=0.092< α) in reducing SPM by (y=2762-944.8x). The majority of respondents (76.74%) had positive attitudes, meaning that they understand and directly felt the benefit of homegarden, while the rest had average value of attitudes. Attitudes directly influences by tha age, duration of living in the area and occupation. Keywords: Suspended Particulate Matter (SPM), vegetation, homegarden, attitude

Oil palm is a strategic mainstay product with a crucial role in the national economy, and it can also be carbon sink to mitigate the negative impact of global warming when managed in environmentally friendly manner. Therefore, management and surrounding community need to have an understanding of the environment, and pro-environmental attitude and behaviour. Action research, which aimed at mitigating global warming through the local action of environmental education (EE), was conducted toward oil palm plantation employee and surrounding community. The EE programme was expected to be able to shape understanding and pro-environmental attitude and behaviour in the target group. Rapid observation and interview were carried out in collecting data for EE programme development. A needs assessment was conducted in developing the EE subject; based on local environmental problems and gap of target group’s perception of the problems. Global warming-related environmental problems found in the location included air temperature increase, drought and difficulty in determining planting season. Spatial analysis based on 1989 and 2014 satellite imagery showed a decrease of the water body, tree vegetated land and open areas, and an increase in non-tree vegetated land and built land, accompanied by an increase in areas with higher temperature range. Both employees and the community had a good knowledge of the environment, but less in conservation. The environmental education provided for them had been able to increase their perception on environmental conservation. However, repetition and intensive assistance are still needed to strengthen the perception

Environmental problems and their solutions must be introduced to students from an early age through Environmental Education (PLH). One of PLH’s implementations is the Adiwiyata Program. The success of the Adiwiyata Program can be measured by examining differences in knowledge, positive attitudes, and positive behavior towards environmental problems and solutions. This study aimed to analyze quantitatively and qualitatively differences in knowledge, positive attitudes and positive behavior regarding the environment in school that has participated and that who has not participated in the Adiwiyata Program. Data were analyzed using a Likert scale with three categories: 1) good, 2) quite good, and 3) not good. Mann-Whitney U Test analysis was conducted to test the significance of the difference between the two groups of respondents. There was a difference in knowledge, attitudes, behavior and PLH scores in school that has participated in the Adiwiyata Program and that who has not. There was also a difference in student knowledge but not significant between schools participating in the Adiwiyata Program and not participating in the program. Students who participated in the Adiwiyata Program had better PLH scores than those who did not follow the Adiwiyata program
