Abstract

One of the efforts to increase soybean production in Bengkulu is through the use of coastal land. Coastal land improvement is carried out by adding compost fertilizers. In order to meet the nutrient needs for soybean plants in coastal lands, a combination of compost and urea is needed. This study aims to determine the performance of soybean in the application of various types of compost and doses of urea and determine the type of compost and the best dose of urea in coastal lands. The study was conducted in July-August 2020. The study used a 2-factor and 3-replications in Completely Randomized Block Design, the first factor was the type of compost: P1 = Widelia trilobata; P2 = Tithonia diversivolia; P3 = oil palm empty bunches, P4 = water hyacinth. The second factor is the dose of Urea: N0 = 0 kg.ha-1, N1 = 25 kg.ha-1, N2 = 50 kg.ha-1, N3 = 75 kg.ha-1. The soybean used was the variety of Direng 1. The results showed that the type of compost and the dose of urea were not significantly different in the soybean plant performance variables. The application of 4 types of compost as much as 10 tons ha-1 in coastal lands showed poor growth and yield a little. Thitonia compost gives the highest yields of 0.5 ton.ha-1 and 0.48 ton.ha-1 when giving urea 75 kg.ha-1. Soybean yields are still very low, so it is necessary to double the dose of urea in coastal lands. Keywords: Coastal Land, Direng 1, Compost and Urea.

Abstract

West Nusa Tenggara (NTB) Province is one of the seaweed production centers in Indonesia. However, the production of seaweed cultivation has various obstacles, one of which is the quality of the seeds and the growth rate of the thallus which tends to decline. Soaking Eucheuma cottonii seeds using seaweed extracts from Sargassum aquifolium, Ulva lactuca, Turbinaria sp. was able to improve seed quality and production of Eucheuma cottonii. The purpose of this study was to determine the extracted content of Sargassum sp. from the Ekas Gulf, East Lombok, NTB. The method in this study used proximate analysis of Sargassum sp., alginate analysis using the Fourier Transformed Infra-Red (FT-IR) test. The content of N, P, and K substances, water, ash, minerals Fe, Ca, fat and carbohydrates from the dry sample of Sargassum aquifolium taken from Ekas Gulf was 7.22; 0.18; 6,70,12,79; 28.89; 0.12; 3.34; -8.41 and 59.51%. Yield and FT-IR alginate samples were 20%; the hydroxyl group (-OH) at wave number 3467.1 cm -1, 1419.3 cm -1, the carbonyl group (saturated cyclic COC) at the number 1114.04 cm -1.1030.2 cm -1 and the typical CH group pyranose at 880.37 cm -1. Sargassum sp. can increase Eucheuma production by soaking seeds before sowing because they contain many minerals that are needed for eucheuma for growth and development.
