PERBEDAAN VARIASI TAKARAN AIR CUCIAN BERAS TERHADAP KECEPATAN PROSES PENGOMPOSAN TAKAKURA

Abstract

ABSTRAK

Pendahuluan: Indonesia menghasilkan 64 juta ton sampah setiap tahunnya, dimana 60% sampah yang dihasilkan berupa sampah organik. Sampah dapat menimbulkan masalah bagi lingkungan jika tidak dikelola dengan benar. Pengelolaan sampah organik yang mudah dilakukan adalah pengomposan takakura, dimana aktivator yang digunakan adalah air cucian beras. Penelitian ini dilakukan dengan pemberian takaran air cucian beras yang berbeda yakni 20ml, 30ml dan 45ml. Tujuan Penelitian: Mengetahui perbedaan kecepatan proses pengomposan takakura terhadap pemberian air cucian beras 20ml, 30ml dan 45ml. Bahan dan Metode: Jenis penelitian Quasi Experiment, dengan desain penelitian Posttest Only Control Group Design. Ada 3 perlakuan, yaitu Pemberian air cucian beras 20ml, 30ml dan 45ml dengan 3 kali pengulangan menggunakan metode RAL, serta 1 kontrol. Pada masing-masing perlakuan digunakan sampah organik sebanyak 1,5kg. Lama waktu pengomposan dihitung berdasarkan karakteristik fisik kompos, yaitu warna, bau dan tekstur. Hasil Penelitian: Pemberian air cucian beras 45ml matang pada hari yang lebih cepat yaitu pada hari ke-19, dengan suhu 30-37⁰C, kelembaban 55-71%, pH 7,5-7,9, dan C/N 11,718;11,175;12,324 yang  sesuai dengan SNI 19-7030-2004. Kesimpulan: Ada Perbedaan kecepatan proses pengomposan takakura terhadap pemberian air cucian beras 20ml, 30ml, dan 45ml yang dipengaruhi oleh variabel Kelembaban dan pH kompos karena nlai p ≤ 0,05.

ABSTRACT 

Introduction: Indonesia produced 64 million tons of waste annually, of which 60% of the waste generated in the form of organic waste. Garbage can create problems for the environment if not managed properly. Organic waste management that is easy to do is composting takakura, where the activator used is water washing rice. This research was conducted by giving different amounts of rice washing water, namely 20ml, 30ml and 45ml. Research Objectives: To determine the difference in the speed of the takakura composting process to the provision of 20ml, 30ml and 45ml washing water. Methods and Materials: This type of research is a Quasi Experiment, with a Posttest Only Control Group Design research design. There were 3 treatments, namely giving water for washing rice 20ml, 30ml and 45ml with 3 repetitions using the RAL method, and 1 control. In each treatment used organic trash as much as 1.5 kg. The length of time for composting is calculated based on the physical characteristics of the compost, namely color, smell and texture. Results: Provision of 45ml ripe rice washing water on the earlier day, namely on the 19th day, with a temperature of 30-37⁰C, humidity 55-71%, pH 7.5-7.9, and C / N 11.718 ; 11,175; 12,324 in accordance with SNI 19-7030-2004. Conclusion: There is a difference in the speed of the takakura composting process to the provision of 20ml, 30ml, and 45ml washing water which is influenced by humidity and compost pH variables because the value is p ≤ 0.05.
