Guru wajib melaksanakan kegiatan pengembangan keprofesional berkelanjutan (PKB). Salah satu kegiatan PKB guru adalah melaksanakan penelitian. Penelitian yang sesuai dan dapat dirasakan langsung manfaatnya adalah penelitian tindakan kelas (PTK). Dengan melaksanakan PTK diharapkan permasalahan dalam pembelajaran dapat diselesaikan. PTK adalah suatu bentuk penelitian tindakan yang dilaksanakan melalui refleksi diri yang dilakukan oleh guru dalam kegiatan pembelajaran yang dilakukan. PTK dilakukan dengan tujuan untuk memperbaiki atau meningkatkan kualitas pembelajaran. PTK dilakukan dalam beberapa siklus dan setiap siklusnya terdiri dari kegiatan perencanaan, pelaksanaan, pengamatan, dan refleksi. Kata kunci: guru, profesional, penelitian tindakan kelas.

Green chemistry is an emerging field that is concerned with the concept of process design and yielding products that are sustainable and benign to the environment and humans, it was introduced by Anastas in the year 1999 and works on the 12 principles points [1]. The green chemistry fields provide continuously environment-friendly compounds or develop processes that avoid the use of hazardous organic chemicals (benzene, toluene, VOCs solvents). Optimizing the quality of the result as well as enhancing environmental friendliness prove to be a major hurdle in the future of green analytical chemistry. The first action taken by chemists for the design of green pharmaceutical products and industrial-scale processes offers enhanced economic development [2]. The use of green raw materials, and avoiding toxic chemicals are needed to be considered by chemical industries and companies for the safety of workers and environments. Further, these steps account for better yields and lesser waste. In green analytical chemistry (GAC), the environmentalfriendly analyte in samples is of greatest demand. This is important to improve the quality of the sample. The main problems that come in an environment because of using traditional methods can be minimized by Anal. Methods Environ. Chem.
