Malino City in Gowa Regency plays a crucial ecological role as a water catchment area, yet it currently faces the threat of land degradation due to land-use conversion and erosion in hilly areas. This community service activity aims to implement soil conservation while enhancing the economic potential of local residents through the planting of productive fruit tree seedlings. The methods employed include educational socialization, training on planting techniques for sloped land, and the distribution of superior fruit tree seedlings (avocado, durian, and orange). The results indicate an increase in community understanding regarding the importance of permanent vegetation in maintaining soil stability. A total of [Mention number] tree seedlings were planted with the active participation of local farmer groups. In conclusion, the integration of ecological and economic aspects through productive trees creates a sustainable conservation system by providing direct financial benefits to the community, thereby increasing their motivation to preserve the environment in the Malino region.

Kaloran Village is an area characterized by steep slope topography that makes it vulnerable to landslides, especially during the rainy season with high rainfall intensity. Although the landslide risk level in this village is still relatively low and has never caused any casualties, the potential for material losses and psychosocial impacts that may arise still need to be seriously anticipated. Disaster risk reduction efforts in Kaloran Village are carried out through the Disaster Resilient Village Work Program (Destana), which aims to increase the capacity and capability of the community in facing disaster threats. The program implementation method consists of three main stages: preparation through focus group discussions (FGDs) and interviews with stakeholders, preparation of the Destana document containing mitigation strategies and steps, and community empowerment through socialization activities and preparedness training. The results of the study indicate that Kaloran Village is categorized as a Medium Resilient Village with a resilience score of 68.97. This achievement serves as an important basis for strengthening the village preparedness system, which is followed up with the establishment of the Disaster Risk Reduction Forum (FPRB) "Kaloran Tangguh Rescue" as a community coordination forum. In addition, evacuation route maps were produced, which serve as technical guidance in the event of a disaster, and the development of the Destana (Disaster Preparedness and Disaster Management) and Contingency Plan (Renkon) documents, which serve as official guidelines for disaster mitigation and management efforts at the village level. This program demonstrates that active community participation, collaboration between stakeholders, and the development of strategic documents can strengthen village preparedness for the threat of landslides.

This research is to direct the mixture of air and fuel exactly to the top of the midpoint of the dome in the cylinder head. In addition, Squish Head also determines the character of the motorcycle. Moreover, what is very prominent in the initial pull is that if the compression ratio is denser, the pull is lighter. This study aims to determine the effect of changes in the slope angle of the squish head of 15, 17 and 19 degrees on compression and torque. In this study, experimental research is used with a quantitative method, where information that can be calculated and measured is factual because it is in the form of numbers. Researchers to get the data will conduct tests using the dynotest tool. Changes in the slope of the squish head have an effect on the torque. At an angle of 15 degrees, torque is produced at 9.91 N.m at 6000 RPM engine rotation. Then at an angle slope of 17 degrees, the torque increases by 0.14 N.m to 10.05 N.m at 6000 RPM engine rotation. At an angle of 19 degrees, the torque increases by 0.17 N.m to 10.22 N.m at 6000 rpm.

The village of Banjarasri, located in the Kapanewon Kalibawang district of Yogyakarta Special Region, has great natural potential that can be developed into a tourist destination. One of the planned locations is Watu Belah Hill. The purpose of this community service activity is to identify the existing conditions of the development of Watu Belah Hill tourism and provide effective planning recommendations for the site. The methods used in this community service activity are surveys, observations, planning, and socialization to the local village officials. Based on the survey and observation results, it is found that the slope condition at the location of Watu Belah Hill tourism development has a slope angle of 160-400 with moderate potential for landslides. The geotechnical team of this community service activity recommends slope reinforcement using terracing and gabion structures for the development of Watu Belah Hill tourism.
