Abstract: Waste management by composting is an alternative way that is considered most appropriate to deal with the problems of wet domestic waste.The purpose of this study was to develop a user guide for the experiment of composting wet domestic waste for the subject Environmental Change/Climate and Waste Recycling for 10th grade SMA/MA and to evaluate the effects of the use of rotten pineapple extract as the starter with the concentrations of 0%, 25%, 50 %, and 75% in the length of time of composting process.MAN 3 Malang was one of the schools in the city of Malang that had implemented Curriculum 2013, which contained the particular topic for the 10th grade.The results of the validation from materials experts, media specialists, and field experts resulted in the score of 94%, 93%, 99% respectively, and the test results from the students obtained the percentage of 91%.Based on the validation results it was concluded pedaltrain pt 1 that the teaching materials were suitable as an alternative instructional materials in the teaching of Biology for class X IPA.
The results of experimental studies indicated that the starter from the rotten pineapple extract in concentrations 75% was the most effective in speeding up the composting process.Keywords: rotten pineapple extract, user guide experimental composting, wet domestic waste Abstrak: Teknik pengelolaan sampah dengan pengomposan merupakan alternatif penanganan yang dianggap paling madelaine chocolate advent calendars sesuai untuk menangani permasalahan sampah basah rumah tangga.Tujuan dari penelitian ini adalah (1) untuk mengembangkan buku petunjuk percobaan pengomposan sampah basah rumah tangga pada materi Perubahan Lingkungan/Iklim dan Daur Ulang Limbah untuk siswa kelas X SMA/MA; (2) untuk meneliti pengaruh pemberian starter sari nanas busuk dalam konsentrasi 0%, 25%, 50%, dan 75% terhadap lama waktu pengomposan.Hasil penilaian angket validasi ahli materi, ahli media, ahli lapangan terhadap bahan ajar berturut-turut memperoleh persentase skor sebesar 94%, 93%, 99% dan hasil uji coba pada siswa mendapatkan persentase sebesar 91%.Berdasarkan hasil validasi para ahli tersebut dapat dikatakan bahwa bahan ajar layak digunakan sebagai salah satu alternatif bahan ajar dalam pembelajaran Biologi kelas X IPA.
