Sidenreng Rappang districts is one of the rice producing centers in South Sulawesi. Along with the increasing amount of rice production, the waste produced by the production process also increases. Rice husk is a waste from the rice milling industry. Rice husk ash has very high pozzolanic activity so that it has the potential to be used as a substitute material or as a cement additive in a mixture of building materials such as paving blocks. Paving blocks are widely applied for road pavement, such as sidewalks, parking areas, residential streets, harbor areas, parks and others. Through the Community Partnership Program (PKM) efforts will be made to empower the community by involving farmer groups and youth youth groups in Kab. Sidrap in order to improve the economic life of the community. Communities are taught appropriate technology in making paving blocks through the use of press machines to produce paving made from raw rice husk ash which is expected to replace paving blocks from a mixture of cement and sand.
Lightweight concrete technology develops along with construction needs. Styrofoam is an alternative ingredient that can be used in a mixture of concrete to produce lightweight concrete. Experimental research to see the performance of lightweight concrete with the addition of styrofoam. This study uses two types of samples, namely concrete cylinders and beams. The compressive strength and deflection tests were carried out on four types of concrete with various styrofoam mixtures. The results showed that the styro-con performed equivalent to regular concrete based on deflection and strength.
This study aims to find out the role of institutions in irrigation management. The type of research used is quantitative with a descriptive and correlational approach. The population in this study were all farmers in the irrigation area of Layoa Village, Bantaeng Regency. The sampling technique used purposive sampling in order to obtain 200 samples. Based on the results of the study it was found that the institutionalization of farmers in managing irrigation canals in Layoa Village, Bantaeng Regency was in the very high category. These results indicate that WUA's organizational ability in managing irrigation assets will result in a good understanding of farmers on how to distribute water. Furthermore, P3A organizations are also very concerned about the protection and implementation of irrigation systems that will reduce the risk of farmers' complaints about irrigation water regulations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
