The low production yields of rice among farmers in Sawaru Village is caused by the scarcity of chemical fertilizer and its high price in planting season, so farmers cannot buy fertilizers as needed by plants. In contrast, farmers have cows whose droppings or waste has potential to become fertilizers, in both solid and liquid forms. At the same time, waste of rice straws can be processed and used as food sources during dry season and planting season, when fresh feed is limited. Cow and rice integration system is the best solution to increase farmer’s income. The activities aim at optimalizing the resources owned by the farmers through cow and rice integration activities, applying the technology of rice waste utilization to be cattle feed, applying the technology of cow droppings utilization to be organic fertilizer applied on rice plants. The location of activities is in Sawaru Village Camba Subdistrict South Sulawesi Province and it took place from March to June 2018, The method used is in the form of counselling, training, demonstration plot (demplot) making and supervision. The results of the activities show the farmer’s increasing knowledge and skills in applying cow and rice system, the making of fermented feed from waste of rice straws, the making of organic fertilizer, increasing utilization of resources owned by the farmers, and increasing agriculture business income that doubles the previous income before the application of integration pattern.
Mathematics is a field of study that plays an important role in the world of education. Mathematics as a science that must be mastered because it supports and is interelated with other subjects. The background of writing this article is the low ability of students to solve mathematical problems. This research was conducted because there are still many teacher centered learning acitivities.To improve the ability to solve the need for an approach model that an be developed to position students as learning centers is the application of scientific models.the scientific approach is an approach aimed at students. In learning activities direct students to be active and understand the concept. This study aims to apply a scientific approach to Dharma Kartini Junior High School students. The research target was class VIII with a 28 students on the subject matter of a two variable linear equation system. The research conducted was classroom action research.Classroom action research trains critical, systematic thinking, starting from planning, implementing, observing and reflecting. This study provided instruments, namely pre-test and post-test in the form of 5 questions of problem solving abilities to students which were carried out in 2 cycles. The research results obtained for the first cycle showed that students mastery of mathematical concepts was still not good. Therefore, proceed to the next stage, namely the second cycle. Based on the implementation of learning in the second cycle, a very significant increase was obtained. Thus it can be concluded that the scientific approach can be applied in learning to improve problem solving abilities in the matter of a system of two variable linear equations.
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.
