Abstract

The Serayu River Basin (DAS) spans 180 km and traverses several districts in Central Java, including Wonosobo, Banyumas, Banjarnegara, Cilacap, and Purbalingga. Significant pollution has been observed in the Serayu River Basin, with the primary sources of pollution being agriculture, industry, and community activities. The objective of this investigation is to evaluate the Serayu River Basin's condition in relation to the STORET method and Class I, II, III, and IV water quality standards, as well as physical and chemical parameters. Ex situ analysis of water samples was implemented through purposive random sampling in the survey methodology. Class I pollution levels in the Serayu River Basin are classified as Category D, which denotes substantial pollution, according to the STORET method. Class II is classified as Category C, which denotes moderate pollution, as indicated by a STORET index value of -26. Several research locations exhibit water parameters that exceed the quality standards, including pH, DO, COD, phosphate, and ammonia. In order to preserve the purity and condition of the Serayu River Basin, it is necessary for all stakeholders, including the community, to participate. Furthermore, the management of the Serayu Watershed necessitates the implementation of control strategies or efforts. Keywords: Basin; River pollution; Serayu; STORET; Water Quality

Abstract

This study aims to explore the design process of Acehnese local history teaching materials oriented toward strengthening students’ social cohesion. The research employed a qualitative case study approach involving six social studies teachers, twelve students, and two curriculum developers selected through purposive sampling. Data were collected through classroom observations, interviews with teachers and students, and analysis of curriculum documents and teaching materials. Data were analyzed using Miles and Huberman’s interactive model, which includes data condensation, data display, and conclusion drawing and verification. The findings indicate that local history learning in Aceh remains dominated by elite-centered narratives and does not adequately represent the roles of cross-ethnic and cross-class actors in shaping social cohesion. Empirical evidence shows that integrating alternative sources—such as local archives, oral histories, and multi-perspective case studies—broadens students’ understanding of social cohesion as a historically constructed process formed through interaction and social negotiation rather than as a given condition. These findings underscore that strengthening social cohesion through history education requires a shift from single narratives toward contextual and inclusive instructional design. However, challenges remain in the availability of contextual teaching resources and pedagogical strategies. Overall, the study highlights the importance of systematically designing local history teaching materials aligned with social cohesion theory to enhance the role of history education in fostering national character.
