yesterday I was field trip to the village and Kotagede Sukunan. I field trips with friends and school. in Sukunan we learn process waste. garbage could be turned out good stuff, too. eg sheaths NutriSari, pop ice, etc. could be used as bags, purses, tablecloths, and many more. there also exist a unique motorcycle with eggshells. so that treat wastewater. in Kotagede us to the tomb of kings. there are baths. but it should not be bathing place we use, so we just look around. there we are also into Kotagede market. but I’m in the market do not buy anything just to see it. after that we all return home.
