Abstract

Salah satu metode untuk mengurangi kekurangan unsur hara pada lahan yakni dengan menggunakan amelioran (pembenah tanah) dari kompos feses Walet sebagai sumber hara organik. Feses Walet memiliki potensi untuk menambah kandungan bahan organik pada lahan pertanian. Tujuan penelitian adalah untuk melihat pengaruh kompos feses walet terhadap pertumbuhan dan produksi tanaman bawang merah. Penelitian dilaksanakan di lahan percobaan Fakultas Pertanian, Peternakan dan Perikanan Universitas Muhammadiyah Parepare. Penelitian ini menggunakan metode eksperimen dengan pola Rancangan Acak Kelompok (RAK). Perlakuannya berupa pemberian dosis kompos feses burung walet dicampur tanah dalam 3 taraf dan 3 ulangan, yaitu tanpa kompos feses walet atau kontrol, pemberian10 ton.ha-1, dan 20 ton.ha-1. Pengambilan sampel tanah dilakukan sebelum aplikasi dan setelah aplikasi. Sampel tanah diambil secara acak pada petak perlakuan lalu dikompositkan, kemudian dianalisis di laboratorium. Parameter pengamatan meliputi, Tinggi tanaman, jumlah daun, produksi umbi, sedangkan pada status hara meliputi C-organik, N, P, K, pH dan Rasio C/N. Hasil Penelitian menunjukkan perlakuan pemberian kompos 20 ton.ha-1 memberi respon terbaik pada jumlah daun, tinggi tanaman dan produksi. Status hara sesudah pemberian kompos feses walet juga memberikan respon yang positif dengan adanya peningkatan hara, dan yang terbaik pada pelakuan 20 ton.ha-1.

Abstract

Acidic land is underutilized as agricultural land because of its lack of nutrients and minimal water content. At the same time, acid land is widespread in Indonesia. This study aimed to determine the soil texture and response of tomato plants after applying manure and humic acid from cocoa pod extract. Humic acid was extracted from cocoa pod skin compost using the Tan method, while soil texture was measured using the pipette method. The experimental design used was a randomized block design with 3 treatments of giving organic matter to acid soil, including untreated acid soil, acid soil + manure, and acid soil + manure + humic acid. The results showed that acid soil + manure treatment could reduce the sand fraction up to 53%. In addition, there was an increase in values for all growth and production parameters of tomato plants, including plant height, number of leaves, and tomato fruit weight in acid soil. The addition of manure + humic acid to acid soil can also increase tomato plants' wet weight, dry weight, and root volume.
