Abstract

Excessive and continuous use of inorganic fertilizers can pollute the environment. Therefore, to support sustainable agriculture, other alternatives are needed to meet the nutrients, namely the use of organic fertilizers, such as vermicompost fertilizer. This study used sawdust, banana weevil, cow dung, and vegetable waste as the feed and media for the cultivation of earthworms. This study aims to determine the content of N, P, K, C-org, C/N, and pH in the vermicompost fertilizer product Earthworm cultivation was carried out from December 2020 to March 2021 in Perlabian Village, Kampung Rakyat District, South Labuhanbatu Regency. Worm cultivation was carried out with two feeding treatments. The first treatment was given 1 kg of cow dung which had been diluted with 1 liter of water plus 250 grams of vegetable waste (K1) and the second treatment was given 2 kg of cow dung diluted in 1 liter of water and 500 grams of vegetable waste (K2). Feeding is conducted every 2 to 3 days for 1 month. The results of the next study were analyzed descriptively (comparing the results of the study with the standard compost of SNI-19-7030-2004). The test results showed that K1 vermicompost contained C-Org of 8.89%, N of 0.75%, P of 0.16%, K of 0.26%, C/N of 11.85, and pH of 6.5. The K2 vermicompost comprised C-Org of 10.92%, N of 0.86%, P of 0.16%, K of 0.23%, C/N of 12.69, and pH of 6.5. Based on the results of the analysis, the vermicompost produced in this study met the SNI-19-7030-2004 standard as compost and the K2 vermicompost contained higher organic and nitrogen content than the K1 vermicompost.

Abstract

Perbaikan kualitas lahan merupakan salah satu teknologi yang penting untuk meningkatkan hasil panen dan pendapatan petani serta bisa digunakan secara berkelanjutan. Penggunaan pupuk organik cair dari limbah pertanian merupakan alternatif yang dapat dijadikan sebagai sumber nutrisi bagi tanaman. Pengabdian ini bertujuan untuk meningkatkan pengetahuan terhadap petani mengenali pentingnya penggunaan bahan organik sebagai amelioran tanah untuk memperbaiki kesuburan tanah dan meningkatkan kemampuan tanah dalam menyerap serta mentransportasikan hara ke tubuh tanaman sehingga menghasilkan panen yang lebih baik dan berkelanjutan. Dari sosialisasi yang dilakukan petani Lestari di Kelurahan Bakaran Batu Kecamatan Rantau Selatan, sebagian besar petani melakukan budidaya hortikultura dan tanaman palawija. Namun, memiliki keterbatasan dalam pengolahan lahan karena memberikan bahan organik segar dari kotoran ayam yang bersifat panas sehingga mengganggu pertumbuhan tanaman dan tanaman cabai yang dibudidaya relatif sedikit. Selanjutnya, permasalahan petani ditemukan pada masa bera tanah yang relatif singkat tanpa pemberian bahan organik sehingga tanah di lahan petani menjadi lebih keras, berwarna cerah dan bersifat masam. Pengabdian di kelompok tani Lestari memberikan solusi berupa pembagian pupuk organik cair dan memberikan pemaparan cara mengolah limbah kotoran ayam menjadi kompos dengan cara inkubasi, masa pengolahan tanah dan pemberian bahan organik pada saat pengolahan. Tindak lanjut dari pengabdian ini direncanakan kerjasama antar petani, penyuluh dan perguruan tinggi untuk melakukan pecobaan demplot di lapangan menggunakan bahan organik dari yang dibuat oleh petani pada saat sosialisasi tahap awal.
