Abstract
A complicated problem for big city governments today is the increasing volume of solid waste, due to population growth and mobility so that the waste load will also increase, especially in metropolitan cities such as Makassar City. To reduce the rate of organic waste generation, which is 60%, is to use organic waste as compost, both liquid and solid. The purpose of this study was to compare the effectiveness of composting with EM4 and MOL activators. The results of the study with the addition of EM4 activator, MOL activator and without the addition of activator from the first day to the fourteenth day the compost structure was different. The addition of MOL produces a slightly coarser structure compared to the addition of EM4, while the compost without activator still smells like wet waste. The quality (C/N) of compost, the addition of 100 ml of EM4 was in the optimum level, while the addition of 100 ml of MOL was less than optimum.

Profil sampah di Indonesia masih didominasi sampah organik (60%), sampah plastik (15%), sampah kertas (10%) dan lainnya sekitar 15%
Penimbunan sampah di TPA (69%), kubur (10%), daur ulang dengan prinsip 3R (7,5%), bakar (5%) dan lainnya tidak terkelola (8,5%)
Summary
Tujuan penelitian untuk mengetahui perbandingan efektivitas pembuatan kompos dengan activator EM4 dan MOL. Lakukan penyemprotan setiap kali melihat atau membuka sampah kecuali pada ember/tong ketiga (control) dan tutup kembali ember / tong dekomposter rapat-rapat, Selama ± 7-14 hari peneliti melakukan 4 kali mengamatan atau 2 kali dalam seminggu, Kemudian tuang kompos yang telah berbentuk bubur, Kompos merupakan pupuk yang dibuat dari sampah organik yang sebagaian besar berasal dari rumah tangga, Aktivator adalah adalah bahan tambahan yang mampu meningkatkan penguraian mikrobiologis dalam tumpukan bahan organik, Larutan Mikroorganisme Lokal (MOL) adalah cairan yang terbuat dari bahan-bahan alami seperti sisa pencucian beras, yang disukai sebagai media hidup dan berkembangnya mikroorganisme, EM4 (Effective Mikroorganisme 4) merupakan bakteri fermentasi bahan organik tanah untuk menyuburkan tanaman dan menyehatkan tanah. Hasil pengamatan Aktivator EM4 secara fisik melalui warna, tekstur dan bau selama proses pengomposan Hasil penelitian kompos setelah dilakukan penyemprotan dari ke tiga buah wadah yang masing-masing 10 kali (10 cc) penyemprotan untuk setiap pengecekan sehingga mengalami perubahan warna coklat kehitaman.
