Abstract

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.

Abstract

Sand tailings derived from tin post-minings activities have high porosity, low water holding capacity, and low organic matter content. These conditions causes soil water defi cit, especially in dry season. To increase the successful of sand tailings revegetation with rubber tree, it is important to select some rubber tree clones based on their adaptability on the sand tailings conditions, especially drought stress. This research aimed to study the response of several rubber tree clones to the frequency of watering on sand tailings. The experiment was conducted in a plastic house at the experimental station of Agrotechnology Study Program of Bangka Belitung University, Sungailiat for 4 months. The experimental design was a factorial randomized block design with two factors and three replications. The fi rst factor was the frequency of watering (every day, every 3 days, and every 5 days), the second factor was a combination of recommended rootstock clones and recommended latex clones (clone GT 1 + PB 260, GT 1 + IRR 118, and PB 260 + BPM 24). The results showed that watering every 5 days caused drought stress resulted in impaired growth of rubber in sand tailings media derived from tin post-mining. The combination of rootstocks and scions PB 260 + BPM 24 and PB 260 + IRR118 were categorized as moderately tolerant clones while GT 1 + PB 260 was categorized as sensitive clones to drought stress in the sand tailings media.Keywords: drought tolerance, watering frequency, rubber tree clones, sand tailings

Abstract

Kebutuhan bawang merah di Indonesia terus mengalami peningkatan. Produksi nasional belum mampu memenuhi permintaan akibat keterbatasan lahan, ketergantungan iklim, dan teknik budidaya yang belum optimal. Inovasi penggunaan True Shallot Seed (TSS) menjadi alternatif sumber benih dengan keunggulan pertumbuhan seragam, serta pengurangan ketergantungan pada umbi. Tahap awal penggunaan TSS masih menghadapi kendala pada proses perkecambahan sehingga perlu dikaji pengaruh lama perendaman air hangat dan varietas terhadap pertumbuhan benih TSS bawang merah. Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman air hangat terhadap pertumbuhan dua varietas benih True Shallot Seeds (TSS) bawang merah, serta menentukan kombinasi perlakuan yang optimal. Rancangan acak lengkap faktorial digunakan dengan dua faktor, yaitu lama perendaman (60, 120, dan 180 menit) dan varietas (Lokananta dan Merdeka). Hasil menunjukkan bahwa lama perendaman berpengaruh nyata terhadap kadar air, keserempakan tumbuh, panjang radikula, panjang plumula, dan tinggi bibit. Varietas Merdeka memperlihatkan viabilitas dan keserempakan tumbuh lebih tinggi dibandingkan Lokananta. Kombinasi perlakuan terbaik diperoleh pada perendaman 120 menit dengan varietas Merdeka, yang menghasilkan daya tumbuh 95,56% dan keserempakan tumbuh 85,56%. Lama perendaman air hangat berpengaruh terhadap kadar air, keserempakan tumbuh, panjang radikula, dan tinggi bibit benih TSS bawang merah, dengan durasi 60–120 menit menunjukkan kondisi yang lebih sesuai dibandingkan perendaman lebih lama. Varietas berpengaruh terhadap persentase daya tumbuh benih, kadar air, keserempakan tumbuh, potensi tumbuh maksimum, panjang radikula, dan tinggi bibit benih TSS bawang merah. Varietas Lokananta berpengaruh nyata pada vigor awal, sedangkan Merdeka berpengaruh nyata pada keserempakan tumbuh dan potensi tumbuh. Interaksi antara kombinasi lama perendaman dan varietas berpengaruh terhadap persentase daya tumbuh, kadar air, potensi tumbuh maksimum, indeks vigor, laju pertumbuhan, kecepatan tumbuh, dan panjang radikula. Kombinasi perendaman 120 menit dengan varietas Merdeka memberikan respon yang paling seimbang.
