Kata Pengantar

P

endidikan kesetaraan sebagai pendidikan alternatif memberikan layanan kepada mayarakat yang

karena kondisi geografi s, sosial budaya, ekonomi dan psikologis tidak berkesempatan

mengiku-ti pendidikan dasar dan menengah di jalur pendidikan formal. Kurikulum pendidikan kesetaraan

dikembangkan mengacu pada kurikulum 2013 pendidikan dasar dan menengah hasil revisi berdasarkan

peraturan Mendikbud No.24 tahun 2016. Proses adaptasi kurikulum 2013 ke dalam kurikulum pendidikan

kesetaraan adalah melalui proses kontekstualisasi dan fungsionalisasi dari masing-masing kompetensi

dasar, sehingga peserta didik memahami makna dari setiap kompetensi yang dipelajari.

Pembelajaran pendidikan kesetaraan menggunakan prinsip fl exible learning sesuai dengan karakteristik

peserta didik kesetaraan. Penerapan prinsip pembelajaran tersebut menggunakan sistem pembelajaran

modular dimana peserta didik memiliki kebebasan dalam penyelesaian tiap modul yang di sajikan.

Kon-sekuensi dari sistem tersebut adalah perlunya disusun modul pembelajaran pendidikan kesetaraan yang

memungkinkan peserta didik untuk belajar dan melakukan evaluasi ketuntasan secara mandiri.

Tahun 2017 Direktorat Pembinaan Pendidikan Keaksaraan dan Kesetaraan, Direktorat Jendral Pendidikan

Anak Usia Dini dan Pendidikan Masyarakat mengembangkan modul pembelajaran pendidikan kesetaraan

dengan melibatkan Pusat Kurikulum dan Perbukuan Kemdikbud, para akademisi, pamong belajar, guru

dan tutor pendidikan kesetaraan. Modul pendidikan kesetaraan disediakan mulai paket A tingkat

kompe-tensi 2 (kelas 4 Paket A). Sedangkan untuk peserta didik Paket A usia sekolah, modul tingkat kompekompe-tensi 1

(Paket A setara SD kelas 1-3) menggunakan buku pelajaran Sekolah Dasar kelas 1-3, karena mereka masih

memerlukan banyak bimbingan guru/tutor dan belum bisa belajar secara mandiri.

Kami mengucapkan terimakasih atas partisipasi dari Pusat Kurikulum dan Perbukuan Kemdikbud, para

akademisi, pamong belajar, guru, tutor pendidikan kesetaraan dan semua pihak yang telah berpartisipasi

dalam penyusunan modul ini.

Setelah melihat contoh-contoh hasil percobaan indikator alami, anda sangat tertarik kan?. Cobalah buat indikator alami dari bahan yang ada disekitar anda, catat warna ekstraknya, lakukan pengujian dengan menggunakan asam (misalnya cuka), basa (misalnya sabun) bila terjadi perubahan warna dalam asam dan basa maka ekstrak tersebut dapat digunakan sebagai indikator.
