Abstract

One of the efforts to improve students' argumentation and critical thinking skills in 21st century learning is to apply problem solving learning models by paying attention to students' academic abilities. The type of research used is quasi-experimental with a 2x2 factorial design. The study population was students of class VIII SMPN 18 Padang, while the research sample was students of class VIII.8 and class VIII.7 by taking samples based on certain criteria. The instrument is a data collection technique with a written test. Data analysis was performed by testing the two-way ANOVA hypothesis using SPSS. The results showed that: (1) the problem-solving learning model affected students' argumentative skills and critical thinking. (2) the problem-solving learning model affects the argumentative and critical thinking abilities of students with high and low academic abilities. (3) there is no interaction between the problem-solving learning model and the academic ability of students 'argumentation skills (4) there is an interaction between the problem-solving learning model and the academic ability of students' critical thinking skills. To sum up, problem solving learning model is able to realize students who have critical thinking skills and arguments that can compete in the era of globalization needed in this 21st century education

Abstract

Rabbits are a group of animals that are very popular and enjoy doing the community. Rabbits in general have high biological and economic potential to produce quality meat, skin and hair, as well as pets (ornamental) and as modern business farming. Rabbits are well known to the people of Indonesia and developed mostly for rabbit farming. To obtain information about this, this study will discuss the objective of knowing the morphometric characteristics and genetic distances of rabbits. The parameters observed were head length, head width, ear length, ear width, chest circumference, chest width, chest width, humerus bone length, radius-ulna bone length, tibia bone length, and body length. The results of body variables measurement in FG rabbits had a higher mean for body size PK (12.64 cm), PTL (13.59 cm), LTL (6.47 cm), PH (9.52 cm), PRU (8, 95 cm) and PB (41.97 cm) for body size compared to other families. Genetic distance shows that it has a fairly close genetic distance (0.63106), while the farthest genetic distance is found in Rexb rabbits and ES rabbits, which is as far as 6.96749. Estimation of genetic distances and tree phenogram construction results from the estimation of kinship between other rabbit clumps.

Abstract

A Watershed is a land area that is an ecosystem unit with rivers and their tributaries that function to accommodate, store, and drain water that comes from rainfall to lakes or seas naturally, whose boundaries on land are topographical and separator boundary in the sea up to the watering area which is still affected by land activities. Characteristics and ecological conditions of the watershed environment are influenced by changes in spatial use patterns with reduced land cover in the watershed area will affect watershed conditions. Human intervention with various activities, especially economic, industrial and residential activities in the upstream to downstream watershed areas affects the water cycle (hydrological cycle) as well as the quality and quantity of the aquatic ecology of the watershed environment. Efforts to maintain the availability of green open space in the watershed area is one of the important things to be able to maintain and maintain water ecology in the Cisadane watershed in addition to various efforts to maintain the water quality of the watershed so that various unique aquatic biota can still be maintained and well maintained. The involvement of local governments, stakeholders, and the community is one of the most important things in preserving and maintaining the environmental conditions of watersheds.

Abstract

The Musi Watershed as a priority watershed is also contained in the Decree of the Minister of Forestry No. SK.328/Menhut-II/2009. The Musi watershed with an area of about a million ha is one of the 108 watersheds in Indonesia that was designated by the Minister of Forestry Decree No. SK.328/MenhutII/2009 as a priority watershed because of its critical condition. This condition is indicated by the area of critical land with a moderately critical to very critical category which reaches 1.7 million ha. Another indication is that the remaining forest cover in South Sumatra is 1,346.8 ha (± 15.6% of the total area of South Sumatra). Musi watershed is simply an area unit that drains water to the same point which is influenced by various ecosystems in it, such as Peatland is a unique ecosystem that has economic value, ecological value, and environmental function, and downstream there is a Mangrove ecosystem and Estuaries, this ecosystem from ecological and environmental functions, among others, has a high biodiversity value, a hydrological function in the management of storage and release of water, as well as a carbon storage function. South Sumatra has a peat area of 14 million ha or 16.3% of the total area, and this condition is one of the potential natural resources to be managed and utilized for the benefit and welfare of the entire community.

Abstract

AbstractSanitation and environmental health are complex problems facing Indonesia today. If these problems are not addressed immediately, this will certainly have an impact on sanitation and environmental health in the settlements themselves, such as the emergence of germs. So this literature review aims to describe the description and handling strategies of slums settlements in Batang Arau Village, Padang City regarding sanitation and environmental health. The method used is qualitative and literature review. The results of the study show that the settlements in Batang Arau Village, Padang City have mild, medium, and large slums sanitation categories. The environment street and drinking water supply are in the low category. The medium category includes buildings, waste water management, and solid waste management. While environmental drainage and fire protection are included in the large category. The handling strategy that can be taken to deal with these slums settlements are to carry out a socialization program in the form of the Kotaku Program, create an environment-based slums settlement concept, carry out a community empowerment/ human resources (HR) strategy, carry out sustainable slums management, and carry out area management plans settlement. If this strategy is carried out, it will reduce slum settlements in the PadangCity.Keywords: Batang Arau Village, environmental health, slums, sanitation, handling strategies

Abstract

This research was carried out in rivers and estuaries in the Batang Naras River, Padang Pariaman Regency, West Sumatra. The river is often used by residents for pond irrigation and ice factory cooling machines. This activity will indirectly affect the biota in rivers and estuaries. Macrozoobenthos is one of the biological aspects that play an important role in assessing the quality of water. The purpose of this study was to determine the community structure of macrozoobenthos in the estuary of Batang Naras. The method used is a descriptive survey. Sampling was done by purposive sampling by setting up 3 research stations. Based on the research results found 2 phyla, namely Arthropoda and Mollusca, 3 classes namely Crustacea, Insects, and Gastropods, 6 orders, 11 families, and 12 genera. The highest benthic diversity index (H') was found at station I at 1.803 and the lowest was found at station III at 1.222. This zone belongs to lightly to moderately polluted waters and the dominance value is 0.5. Diversity and dominance show moderate values. The influence of industrial activities and aquaculture disturb the amount of benthos in the estuary.

Abstract

Ecology which studies individual organisms is called autecology, the environment is mainly studied in environmental science which is applied ecology with the aim that humans can apply the basic principles and concepts of ecology in the living environment. In ecology, the relationship between living things and their environment is objective, humans are seen as equal to other living things. In environmental science, humans are distinguished from other living things, and the view of the relationship between humans and the environment is subjective (ecology and environmental science). In ecology, interactions are not only between organisms and abiotic components but also between living organisms themselves. Interactions can occur between organisms of the same type or population.
