Abstract
Inonu I, Kusmiadi R, Yuliana A, Nurtjahya E. 2020. The amelioration of post tin mining sand tailing medium with chicken manure for pepper cultivation. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 31-40. Pepper cultivation in tin mining sand tailings requires the amelioration of organic matter to improve soil characteristics. The paper investigates the effect of chicken manure dosage on the growth of three pepper cultivars in sand tailing medium. This study was conducted on April-August 2016 at Experiment Station of Universitas Bangka Belitung, Balunijuk Village, Bangka Island. This study was arranged in a completely randomized design with two factors and three replications. The first factor was the dosage of chicken manure (5 kg; 6 kg; 7 kg/plant). The second factor was pepper cultivars (Lampung Daun Lebar; Lampung Daun Kecil; Merapin). The. result of the analysis of variance showed that the treatment of chicken manure dosage significantly affected only on total leaf area. The treatment of pepper cultivars significantly affected the total of chlorophyll, root dry weight, and shoot dry weight. There was no interaction between chicken manure dosage and pepper cultivar. Pepper cv. Lampung Daun Lebar tends to grow better than the other cultivars in the sand tailing medium.
Highlights
Bangka Island is the largest tinproducing island in Indonesia
This study was conducted at Experiment Station of Universitas Bangka Belitung, Balunijuk Village, Bangka Island.on AprilAugust 2016
Based on the results of the analysis of variance (Table 3), it was shown that the manure dosage treatment did not significantly affect all observed variables, except the leaf area
Summary
Bangka Island is the largest tinproducing island in Indonesia. The area of tin mineral mining license (IUP) onshore is236,390.33 ha Bangka Island is the largest tinproducing island in Indonesia. The area of tin mineral mining license (IUP) onshore is. Reported that about 79,163 ha of tin mining land on Bangka Island, while according to Sukarman and Agustian (2016), 80,018 ha of ex-tin mining land on Bangka Island consisted of 72,400 ha of land area (90,48%) and ex-mining pit about 7.618 ha (9,52%). One of the impacts of tin mining activity is the formation of tailings land. The tin mine tailings land has a low soil fertility status, indicated by the dominance of the sand fraction and low soil pH, organic carbon, cation exchange capacity, and essential macronutrients (Asmarhansyah et al, 2017)
