Abstract

Buah tomat (Lycopersicum esculentum Mill.) merupakan salah satu produk pangan penting, selain itu tomat merupakan bahan baku industry dan kosmetika bahkan sebagai bahan obat-obatan, namun produksinya masih fluktuatif dari tahun ke tahun karena umumnya dibudidayakan pada tanah marjinal. Tujuan penelitian ini adalah untuk mengetahui pengaruh pupuk kandang kambing dan bokasi limbah pasar terhadap pertumbuhan dan hasil tomat pada tanah Ultisol. Penelitian menggunakan Rancangan Acak Kelompok pola factorial, dengan 3 ulangan. Faktor pertama adalah pupuk kandang kambing (K) yang terdiri dari 4 taraf yakni: K0= tanpa perlakuan, K1= 300 g polybag-1, K2= 400 g polybag-1, K3= 500 g polybag-1. Faktor kedua adalah bokasi limbah pasar (P) yang terdiri dari 4 taraf yaitu P0= tanpa perlakuan, P1= 300 g polybag-1, P2= 400 g polybag-1, P3= 500 g polybag-1. Hasil penelitian menujukkan bahwa penggunaan pupuk kandang kambing dan bokasi limbah pasar secara nyata meningkatkan tinggi tanaman, jumlah daun, jumlah buah dan bobot buah per tanaman. Aplikasi 500 g pupuk kandang kambing dan 500 g bokasi limbah pasar masing-masing mencatatkan bobot buah terberat yakni 242,12 g dan 197,27 g per tanaman.

Abstract

Nickel is a fundamental natural resource with high economic value as a raw material for the stainless steel industry, vehicle batteries, electronic products, military weapons, and other industries. Unfortunately, the exploitation of nickel ore through open-pit mining creates a negative impact on the soil and ecosystem. A study was conducted to evaluate the effects of rice husk biochar and cow manure towards the Fe and Ni content and several soil chemical properties and patchouli growth on nickel-mined soil. The study was conducted at the Experimental Farm of the Faculty of Agriculture, Halu Oleo University, from August to November 2023. This study was set up in according to the randomized block design in a factorial pattern in which the first factor was rice husk biochar comprised of without biochar, 75, 150 and 225 g polibag-1, while the second one was cow manure consisted of without cow manure, 75, 150and 225 g polibag-1. The results highlighted the increment of soil pH, CEC and available P due to the application of biochar and cow manure, and conversely the Iron (Fe) and Nickel (Ni) content tended to decrease linearly. Co-application of 3% rice husk biochar and 4.5% cow manure results in successful outcome on soil quality and promotes the dry weight of patchouli plants on nickel-mined soil
