The effect of project-based learning in developing naturalist intelligence in children

The existence of plastic waste has long been a conversation that never ends. Although there have been many movements and solutions for handling it, in fact Indonesia is still the largest waste contributor after China. The lack of awareness, concern and ability of our society in managing waste are considered as the causes of the increase of our waste every year. So it is considered necessary to prepare a better generation by providing stimulation and good habituation to the younger generation so that they can become the next generation that will be more environmentally literate. This study aims to see how the impact of the project-based learning approach in developing naturalist intelligence in early childhood. The research used quantitative method (a quasi-experimental design). The sample in this study was 24 early childhood children, with details of the experimental class 10 children, and the control class 14 children. Data collection was performed by using observation sheets and documentation and consequently the data was analyzed statistically using the T-test. As the result, the study found that the project approach increased the naturalist intelligence score of early childhood by 64%. The highest percentage of changes in children's value is in recycling activities: children are very enthusiastic about being directly involved in the process and can channel their ideas and energy in producing works. It can be concluded that the project-based learning approach affects children's naturalist intelligence and can be used as a learning approach in developing children's naturalist intelligence.

Based on the results, it is found that the Lae Soraya River has a mild pollution status. Considering the testing values and determination of water quality status, the river is not suitable for direct use for hygiene and sanitation needs or as a raw water source for drinking

PENGGUNAAN PEMBATAS ALIRAN (KATUP) JENIS SWING CHECK PADA KERAN AIR UNTUK EFISIENSI AIR WUDU

In Islam, the most frequent need for water is when performing ablution activities. Prophet Muhammad SAW used only 1 mudd of water (about two-thirds of a liter) or about 0.67 liters for ablution. This study aims to determine the efficiency of using a Swing Check type of flow limiter on a water faucet related to ablution activities. The results showed that the flow limiter (valve) of the Swing Check type was able to efficiently use water in an average of 43%. With the Swing Check valve wudu volume per individual is 17.68 l/person before the flow limiter is used this valve and 10.09 liters/person. With this research, it is hoped that in the future we can update technology that can save water, not only in saving water but also in maintaining the existence of water, especially the involvement of water conservation also plays an important role in water conservation

PERAN PEREMPUAN DALAM KONSERVASI AIR RUMAH TANGGA

The availability of world freshwater that can be used by humans is very small in number compared with many people's estimates, especially for those living in regions with abundant of water. Water conservation should be done according to Islamic advice, then considering other users' water needs, maintaining water quality, saving energy, and considering increasing water demand as per population growth. Prior to the scarcity and water damage, water conservation needs to be done in non-domestic and domestic / household levels. Household water conservation can be done through behavioural change and technological change. This study focuses on changes in household behavior in water conservation related to the role of women. A qualitative approach is applied in this study by conducting interviews with resource persons who play a significant role in environmental issues and some are housewives. The results show that household water conservation can be done in simple and easy ways, for example by monitoring water use by children, choosing water-saving ways of gardening, washing clothes at once, and so on. The role of women in household water conservation is significant because women are the main users of water and women can educate children early on. The government is expected to arrange strategies to promote water conservation on a household scale by educating and disseminating it to women's associations at the village level.Keywords :
