Abstract

Information on the ecological status of inland waters is important to know in the framework of management and conservation purposes, including the biota elements of the Macro-zoobenthos community. This study aims to determine the composition and ecology of feeding acro zoobenthos and its relation to the water quality of Lake Maninjau. Lake Maninjau is one of the priority lakes that has an important role both economically and ecologically. Data were collected from journal literacy. There are 34 types of acro zoobenthos with a low diversity index (H= 0.34-0.82). The distribution of each Taxa was less to nearly even (E= 0.30-0.93). The Macro-zoobenthos found belonged to Molluscs, Oligochaeta, EuHirudinea, Insect Larvae, and Crustaceans. Molluscs were the most abundant, spread over 70% of locations and dominated by Corbicula species. The highest abundance is in the Sigiran location. A total of 26 Taxa were characterized by temperature, TDS, and conductivity variables, while the other 8 were characterized by DO and ORP based on CCA results. The feeding Collector ecology group (especially the filter collector) dominates. This indicates that the waters of Lake Maninjau are rich in fine particulate organic matter (FPOM).

Abstract

Watersheds are a method of managing river water resources with the aim of preserving the viability of aquatic resources in the long term. One of the elements needed for management is how the current state of aquatic resources. Reduced flood swamp areas, sedimentation, decreased water discharge and water levels, and difficulties for some fish species to migrate are all effects of environmental modifications such as damming rivers for irrigation and hydroelectric power and changing the mass of water. In the middle and lower reaches of the river, the addition of anthropogenic materials from various industrial activities can have an impact on aquatic life, fish, and fishermen's catches. To ensure the future existence and survival of fish resources in river waters, it is necessary to manage resources, especially watersheds covering aquatic habitats with various species, as well as multi-species habitats. Watershed management considerations must include a variety of factors, including area/ecology, sector, scientific field, and stakeholders.

Abstract

Dams have a very large ability to develop fish culture, then from that the development of fish culture grows rapidly. This rapid progress greatly resulted in a reduction in water quality, good for the life and progress of fish and their food-living creatures. This dam is also used for capturing fisheries, floating net cage aquaculture (KJA), transportation, and tourism. This research is literary research from several posts that study articles on the status of the sustainability of dams and the sustainability of KJA aquaculture in multidimensional sustainability (environmental, economic, and social sciences). Based on the results of policy research on the sustainability of environmental, social, and economic science and fish farming in dam waters, the sustainability of dams as well as the sustainability of KJA cultivation are very supportive of one another. Prolonged management of the dam will help the sustainability of KJA cultivation.

Abstract

Mismanaged plastic wastes still become main environmental problem in many countries. It also believed as the root of many environmental problem today faced by both advanced and develop countries, like Indonesia. Microplastics polluted the aquatic environment of Indonesia today mainly come from mismanaged plastic wastes (secondary), but both of the primary and secondary microplastics exist in Indonesian water. This paper reviews microplastic pollution in Indonesian water focused on two main topics, namely the characteristics of microplastics in Indonesian waters and their sources and effects of the presence of microplastics on aquatic organisms. This article was compiled using secondary data consisting of various data and papers, materials obtained from various sources of relevant and reliable official publications that are closely related to the microplastic pollution in Indonesian waters. These findings were then analyzed in an explanatory descriptive manner to provide an overview of characteristics and the sources of microplastics in Indonesian waters and how microplastics affect aquatic ecosystems. It is hoped that this will provide an opportunity to address this issue more effectively.

Abstract

Based on data analysis from observations and interviews with science teachers at SMPN 22 Padang, it can be seen that the student learning process is still passive, and students' interest and motivation in learning are still lacking. Textbooks are the main teaching materials used by both teachers and students. These problems make it difficult for teachers to carry out the learning process, causing students to have difficulty understanding the learning material. This study aims to produce an e-module based on problem-based learning using Adobe Flash Professional CS6 which is valid, practical, and effective for class VIII SMP students. This type of research is design and development research that uses the Plomp development model. The research data were obtained from validity, practicality, and effectiveness tests. Based on the results of the study, showed that the e-module based on problem-based learning had a validity value of 84.24% with very valid criteria based on the validator's assessment. The results of the practicality assessment by the teacher are 90.68% and the results of the practicality assessment by the students are 87.72% with very practical criteria. Problem-based learning-based e-modules that have been developed have effectiveness with very effective categories in terms of competency assessment in the cognitive domain, affective domain, psychomotor domain, and student learning activities
