Soil stabilization with new hard and cement mixtures.
No full textAt present, one of the development activities in Indonesia is the provision of physical infrastructure, such as construction of road infrastructure, preparation of agriculture land and settlement living areas. Part of these activities are located on peat soil with a variety of thickness which have an extremely low bearing capacity. Consequently, there are many construction problems when building on layers of peat soil. The problems are generally caused by the high permeability, the extremely low bearing capacity, high consolidation properties, especially secondary compression with long duration. A large number of road damage is occuring relatively faster than the expected lifetime, and they often need large costs for road maintenance on that location. Stabilization is one known method in civil engineering to improve the strength of a soil. Cement stabilization is one of several known methods. The results of this research show that Cement (PC) NewHard (NH) admixture can improve the strength of peat to a siginificant value for several contents and proportions. At Optimum Moisture Content (OMC) with 28 days of curing, the addition of 10 % with 50 % PC 50 % NH proportions can improve the Unconfined Compression Strengths (qu) of peat up to 2.28 kg/cm2; an addition of 12 % with 50 % PC 50 % NH up to 3,02 kg/cm2, and an addition of 14 % with 50 % PC 50 % NH up to 3.15 kg/cm2. While without stabilization the Unconfined Compression Strength (qu) of peat was only 0.43 kg/cm2 at OMC condition. The bearing Ratio (CBR) value also increased up to 6.5 % with an addition of 10 % with 50 % PC 50 % NH, 7.0 % with an addition of 12 % with 50 % PC 50 % NH and 9.0 % with an addition of 14 % with 50 % PC 50 % NH, with 28 days curing time. While before stabilization the CBR value was 1.8 %. With more addition of PC NH, the peat strength tended to increase too. So it can be included that the strength and the bearing capacity of peat depend on the addition of PC NH, the curing time and also the peat water content
The Social Construction of Gender in the Experience of Vocational School Adolescents. A Critical Approach
No full textIn the context of vocational high schools, gender role divisions and stereotypes are often reinforced by the educational environment and social practices, which have an impact on career choices, social interactions, and future opportunities for adolescents, so this research aims to analyze how gender norms and stereotypes are formed and maintained in vocational high schools, identifies the social dynamics that influence adolescents' experiences of gender roles, presenting a critical approach to understanding and challenging the social construction of gender in educational institutions. It is also hoped that this research can provide important insight into how vocational education institutions become dynamic spaces in shaping adolescent gender identity. These findings also open a discussion regarding the importance of educational reform that is more inclusive and gender equal, so that it can encourage students to explore their potential without the limitations of gender stereotypes.Through a qualitative approach with in-depth interviews and participant observation, this research explores how patriarchal values, traditional gender norms, and educational policies implicitly shape adolescents' gender identity. This research concludes that the education system in vocational high schools is not gender neutral, but rather reproduces gender-based social injustice. Therefore, efforts are needed to deconstruct gender norms that exist in the curriculum and educational practices, in order to create a more inclusive and fair learning environment for all teenagers, regardless of their gender identity

Improving Student Learning Outcomes Through Discussion Strategies in Islamic Learning at SMP Negeri 2 Idanogawo
No full textThis study aims to improve student learning outcomes in Islamic Education by using Discussion Strategy. This study is a classroom action research that uses four steps, namely planning, action, observation and reflection. The subjects of this study were junior high school students. The data of this study were obtained by test and observation techniques. Tests are used to improve student learning outcomes and observations are used to analyze teacher and student learning activities. The data analysis technique used in this study is descriptive statistics by comparing the results obtained with indicators of research success. The results of the study indicate that Learning with Discussion Strategy can improve student learning outcomes. This can be seen from the increase in the percentage of completeness of improving student learning outcomes in each cycle with details of the pre-cycle 46.56%, the first cycle 78.57% and in the second cycle increased to 89.77%. Thus, the use of Discussion Strategy can be used as an alternative to improve student learning outcomes
