Abstract

Chemicals such as formalin and borax are actually chemicals that can only be used for purposes outside the body, meaning that borax and formalin are not allowed to enter the human body because they will seriously damage the organs inside. The purpose of this study was to determine the presence of formaldehyde and borax in snacks at SMAN 1 Nguter, Sukoharjo. This research method is experimental research then summarizes the entire research. This study used turmeric and dragon fruit extracts as research indicators. The results of several samples that the researchers observed contained formalin, namely sausage tempura, middle star tempura, bread tempura, rolled noodle tempura, star tempura, cireng tempura, thigh tempura, round white tempura. And some of the samples contained borax, namely ice doger and tempura bintang tengah. Based on the results of the study, it was found that there is a danger posed when consuming foods containing a lot of borax and formalin, one of which can damage liver and kidney function and can even trigger cancer.

Abstract

Learning biology directly in the environment provides experiences for students so they can develop an interest in biology. Local potential can be used as a source of learning biology. Biology material has not been linked much in everyday life and is fixated on books. Some biology teachers are less sensitive to the potential in the environment. The solution is to combine biological materials with local potential. The purpose of this article is to identify local potential at SMA N 1 Nguter as a source of learning biology based on local potential on biodiversity material and a form of integrating local potential into biodiversity material. This type of research uses qualitative. As well as an inventory of local plants along with their morphological characteristics using observation and interview methods as well as the types of flowers, the classification is written down. Based on the results of the study, the local potential of flower plants at SMA N 1 Nguter has 5 types of flowers with 12 kinds of colors that can be used as a source of learning biology based on local potential. The form of integrating the potential of flower plants on biodiversity material at the gene and species level can be arranged in modules.
