The use of sengon albasia ash waste as a partial cement substitute in concrete production is carried out to reduce combustion waste and also reduce cement use. This study focuses on the use of sengon albasia wood ash waste. The use of sengon albasia wood ash as a cement substitute causes a significant decrease in the slump test value. The use of sengon albasia wood ash as a partial cement substitute in concrete mixes actually produces different results depending on the proportion. If added as much as 10%, the concrete's compressive strength actually increases, but if it reaches 20% or 30%, the compressive strength actually decreases. This occurs because this type of wood ash has a significant water absorption capacity. As a result, the water that should be used for The chemical activity occurring between cement and water is diminished, so that the bond between the cement mixture as a binder and aggregate as a filler is reduced, and ultimately the concrete's compressive strength also decreases.

This study aims to analyze the effectiveness of natural resource management, particularly water and soil, in increasing agricultural production in Sampali Village, Percut Sei Tuan District, Deli Serdang Regency. The research approach used was descriptive qualitative through field observations, in-depth interviews with farmers and village officials, and documentation studies from relevant agencies. The results indicate that the irrigation system in Sampali Village is not operating effectively, characterized by shallowing of canals, damaged irrigation walls, and blockages that cause uneven water distribution. This condition has a significant impact on crop yields, with a difference in production between upstream and downstream areas reaching 1.9 tons/ha. Furthermore, soil quality has also declined due to the excessive use of chemical fertilizers, as indicated by a soil pH that tends to be acidic (5.4–6.0), low organic matter content (1.2–1.8%), and decreased soil biological activity. Factors influencing the effectiveness of water and soil management include technical, environmental, socio-economic, and institutional aspects. This study concludes that natural resource management in Sampali Village is still suboptimal, necessitating improvements to irrigation infrastructure, increased use of organic fertilizers, and institutional strengthening and farmer mentoring. These efforts are expected to support sustainable agricultural productivity gains.
