Abstract

Inonu, et.al. Use of Composted Chicken Feathers for Lettuce Cultivation in Sand Tailings of ex Tin-Mining Site. JLSO 5(2):145-152.Chicken feathers is a solid waste which can be composted for sand tailings of ex tin-mining site ameliorating. The objective of this research was to analysis the  different doses of composted chicken feathers to obtain the proper dosage for growth and production of lettuce grown on sand tailings of ex tin-mining site. This research used experimental method with Randomized Completely Block Design (RCBD). The treatment factor were doses of composted chicken feathers with five levels (5.0; 7.5; 10; 12.5; 15 tons/ha of chicken feathers) and 20 tons/ha of chicken manure as a control. The results showed  growth and production of lettuce were treated with 20 tons / ha of chicken manure is higher than all treatment of doses of composted chicken feathers. Sand tailings of ex tin-mining site which is treated 12.55 tons/ha composted chicken feathers produced the highest growth and production of lettuce.

Badriah B, Inonu I, Asriani E. 2019. Growth of one year old pepper (Pipper nigrum L.) in post tin mining land using different dosage biofertilizer. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):117-125.    The yield of pepper as important spice plant has been decreased due to the reduction of pepper planting area which are converted into tin mining area. One effort can be done is utilizing suboptimal lands that has low soil fertility. The aim of this research was to determine the effect of biofertilizer dosage on one year old pepper to growth in post tin mining land. This research had been conducted from February 2018 until June 2018 in post tin mining land owned by PT Timah at Dwi Makmur Village, Bangka. The research used expremental method with Completely Randomized Block Design (CRBD) with single factor. The factor was biofertilizer dosage: (0,0; 0,5; 1,0; 5,0; 10,0; and 15,0 g/L/plant). The result showed enrichment biofertilizer significantly effect on chlorophyll content and number of branch, but not significantly on plants height, number of nodes, and leaf area. The treatment dosage 10 g/L/plant (1x108 cfu) was the best inclined result growth of one year old pepper plant in post tin mining land.

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.

Abstract

Pineapple peel waste can be used as liquid organic fertilizer (LOF) to add organic matter and improve soil quality for cultivating crops such as shallots. Shallots re vegetable crops that have great prospects for farmers because of the high demand for shallots that were not in accordance with their production. This study aimed to determine the effect of concentration and frequency of application of LOF of pineapple peel waste on the growth and yield of shallots. This research had conducted in farmer’s land in Perlang Village, Lubuk Besar District, Central Bangka Regency, from January to April 2021. This research used experimental method with a split plot design. The main plot is the concentration of LOF of pineapple peel waste which consists of 30 ml/l and 60 ml/l. Sub-plots are the frequency of application LOF of pineapple peel waste which consists of once in 7 days, once in 14 days, and once in 21 days. The results showed that the concentration of LOF of pineapple peel waste had no significant effect on all observed variables. The frequency of application LOF pineapple peel waste had a significant effect on the number of tillers per clump, but had no significant effect on the other variables. The interaction between the concentration and frequency LOF pineapple peel waste had no significant effect on the growth and yield of shallot plants. LOF application of pineapple peel waste with a concentration of 30 ml/l and a frequency of once every 7 days tends to be better for the growth and yield of shallot plants.
