Learning Environment by using the Inquiry method can bring students into problems directly, so they can develop capabilities in terms of solving environmental problems that will be faced. In addition, the Inquiry method will train students to communicate well between fellow students and teachers (lecturers). The application of inquiry methods is effective in increasing students' competency of the environment and would be skilled in solving problems. By investigations conducted at Tondano Lake, students will be able to prove the truth of a theory by themselves. This type of research is an experiment using descriptive quantitative data analysis techniques by one group pretest-posttest design. This research is intended to describe the presence or absence of a treatment given to the subject of the study. Based on the results of the research and discussion, it was concluded that environmental learning using the inquiry method at Tondano Lake had a significant effect on students' competency. This is evidenced by the average gain score reaching 92.4769 or 94.5% and the implementation of learning which is in the effective category.

Isu global sampah sangat mengkhawatirkan karena berdampak langsung pada lingkungan biotik dan abiotik bahkan telah menyebabkan bencana non alam. Mengurangi sampah dari sumbernya dengan metode pemilahan dan dikelola lanjut menjadi produk baru merupakan cara untuk menangani permasalahan sampah. Mengurangi sampah dari sumbernya dengan pemilahan selanjutnya ditabung di Bank Sampah adalah terobosan yang menjanjikan dan dapat mendorong masyarakat untuk berpartisipasi aktif dalam pengelolaan sampah sekaligus menunjang penerapan green constitution di masa yang akan datang. Tujuan penelitian ini untuk mendapatkan pemetaan wilayah persebaran bank sampah di Kota Manado dalam menunjang penerapan green constitution. Data diperoleh melalui penelitian menggunakan aplikasi pemetaan dan dilakukan dengan mesin pencari google, dengan dasar bahwa aplikasi ini banyak digunakan dalam mencari alamat oleh berbagai pengguna. Data dianalisis menyangkut pemetaan posisi bank sampah yang ada di Indonesia, ditemukan dalam situs milik kementerian lingkungan hidup dan kehutanan dengan nama sistem informasi pengelolaan bank sampah nasional. Namun saat difokuskan pencarian bank sampah khusus di kota Manado, maka aplikasi smash yang dapat menunjukkan lokasi bank sampah yang ada. Hasil penelitian selanjutnya menunjukkan pemetaan posisi bank sampah di kota Manado terdiri dari pusat, pinggiran, dan luar kota. Selanjutnya hasil perbandingan ketiga bank sampah menghasilkan metode pengelolaan yang dapat disimpulkan bahwa pengelolaan bank sampah efektif dilakukan melalui strategi penerapan 3R (Reuse, Reduce, Recycle) dalam pengelolaan sampah pada sumbernya di tingkat masyarakat. Hasil pemetaan diharapkan menjadi dasar pengembangan kebijakan green constitution sebagai pengembangan model pengelolaan bank sampah di masa yang akan datang.Kata Kunci: Pemetaan, Pengelolaan Bank Sampah, Green Constitution, Kota Manado

Unmanaged waste can cause various problems of environmental damage including threatening tourism development. The current waste problem is quite worrying because it can have a direct impact on humans, such as the entry of plastic elements into the human body through fish or food exposed to microplastics. Aim: The waste bank around Lake Tondano tourism object was studied qualitatively with the aim of describing the waste bank management mechanism to be used as a model for developing a waste bank to support sustainable tourism development. Methodogy and Results: The research data was obtained through field research through observations and interviews with waste banks around the Tondano lake tourist attraction, in this case the Mapalus waste bank located in Papakelan Village. Conclusion, significance, and impact study: The results show that the current form of waste bank management on the shores of Lake Tondano is a waste bank that is purely managed by the community. The form of management is to collect waste from the community by first going through a sorting process. After sorting, organic waste is used as fertilizer and inorganic waste is made into valuable products and can be used as souvenirs for tourists.  The waste bank program can reduce the increase in waste directly from the source. In addition, the waste bank can produce new products and provide benefits to the community. The waste bank is also a solution in the context of developing tourism on the coast of Lake Tondano.
