Surabaya, a city with high population density in East Java, faces challenges in managing land for reforestation. To address this issue, the Surabaya Green and Clean (SGC) Program was introduced, focusing on greening and waste management. One of the proposed solutions is hydroponics, a soilless farming method that can be applied on limited land. On July 28, 2024, community service activities were carried out in Kalijudan Village, Mulyorejo District, Surabaya City, to introduce and increase public knowledge about hydroponics. This activity involved socialization and practical hydroponic planting with the participation of 25 residents. The program consisted of preparation stages, socialization, planting practices, and report preparation. Socialization included exposure to hydroponic theory and practical demonstrations, while each participant received tools and materials for home experiments. The planting method with rockwool has proven effective in supporting plant growth, while the distributed eco-enzyme provided dual benefits by increasing plant growth and reducing household waste. This program successfully introduced hydroponic technology and increased awareness of sustainable urban agriculture. Hopefully, this activity will be the first step in developing hydroponics and creating a greener environment in Surabaya.

Groundwater is dynamic and influenced by a number of natural factors. Geology and geomorphology greatly determine the condition of the soil in an area. The geological structure influences the direction of groundwater movement, the type and thickness of the aquifer. The Karubaga District in Tolikara Regency is an area with a morphology of mountains, hills and valleys so it has the potential for rivers and streams that can be used as a source of raw water. Identification of the depth of the groundwater level in the Karubaga District is carried out using tools in the form of the AIDU Golden Rod (AGR), which is a special geophysical study instrument that provides a detailed vertical picture 300 m into the ground surface to read the resistivity values of rocks and aquifers by measuring the natural electric field

A slope is an area of ​​morphology that has a certain geometry, namely the highest and lowest parts and has the potential for landslides if it is in an unstable condition (Wesley & Pranyoto, 2010 in Khodijah, et al, 2022). A slope can be composed of soil, rock, or both. Slope stability is influenced by slope geometry, physical and mechanical characteristics of the slope-forming material, water (hydrology and hydrogeology), rock weak plane structure (location, direction, frequency, mechanical characteristics), natural stresses in the rock mass, local stress concentrations, vibrations ( natural: earthquakes; and human actions: effects of blasting, effects of heavy equipment passing by), climate, the results of mine workers' actions, and thermic effects (Moshab, 1997 in Arif, 2016).

Soil has a very important role in construction, namely in buildings, roads, bridges, dams and other buildings, so soil with adequate technical properties is needed. Work will encounter difficulties if you encounter soil that has large shrinkage characteristics, this causes damage to the building standing on it. To improve the properties of peat soil in the field of civil engineering, soil stabilization is carried out. Soil stabilization is in principle to improve the quality of soil that is not good, or improve the quality of soil that is actually already classified as good. The characteristics of peat soil include: high organic content, easy degradation when exposed to water, and if the soil experiences dryness the soil shrinks. The liquid limit of the original soil was 63.505% and when the lime mixture was added it became 61.46% in a mixture of 5% lime, 53.47% in a mixture of 10% lime, 49.30% in a mixture of 15% lime, and 28.55% in a mixture of lime 20%. The plastic limit of the original soil was 24.03% and when the Gypsum lime mixture was added it became 29.16% in a mixture of 5% lime, 31.11% in a mixture of 10% lime, 34.15% in a mixture of 15% lime, and 36.14% in a 20% lime mixture. As the Plastic Limit value increases and the Liquid Limit value decreases in the soil, the plasticity index of the soil decreases and the cohesive properties of the soil decrease.
