Abstract

Riyanti I, Putri WAE, Ulqodry TZ, Santeri T. 2019. Accumulation of heavy metal Zn and Pb in sediment, root and leaves of mangrove Avicennia alba in Payung Island, South Sumatra. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):141-147. Various industrial activities or natural activity in the Musi River, might contribute to the heavy metals input in mangrove area of Payung Island. The purpose of this study was to analyze the concentration of  heavy metals zinc (Zn) and lead (Pb) in sediment, root and leaves of mangrove A. alba. This research was conducted in January 2018. Analysis of heavy metal used Atomic Absorption Spectrophotometry (AAS). The results indicated that Zn concentration of sediment (13.35-22.61 mg/kg) and Pb (0.14-3.17 mg/kg), was still in quality standard level. Zn concentration in roots was 0.45-4.95 mg/kg and in leaf was Zn 2.46-12.76 mg/kg, while Pb on root and leaves was not detected.  The value of BCF roots, leaf BCF and TF values were 0.15-0.24 ; 0.30-0.59 ; and 1.69-2.47, respectively. The results of this study indicated that mangrove A. alba in Payung Island as moderate accumulator plants category, and plants could transmit heavy metals effectively.

Abstract

Adriani D, Wildayana E, Alamsyah I, Minha A. 2019. Performance and determinants of farmers in  adoption decision of innovation for swamps rice cropping system in South Sumatra. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):181-191. The development of food crops in swamplands became one of  main focus of the government in the development of rice farming in Indonesia. A variety of ecological constraints that accompany the development of agriculture in swamp land overcome by a variety of technological innovations, one of which is with the application of Cropping Index 200 (CI 200) technology. After nearly 5 years of CI 200 technology applied on swamp land is considered necessary for analysis related to the performance of socio-economic of farmers in the adoption of technology innovations CI 200. This study aimed to analyze the socio-economic condition of farmers in adopting IP 200 technology innovation, and analyze the determinants of IP 200 technology adoption decisions. Research was using the survey method and has been carried out in 2 districts, namely Tanjung Lago sub-District, Banyuasin District and Pemulutan sub-District, Ogan Ilir District in June-July 2019. Sampling method used disproportionate stratified random sampling. The analysis of the data was using tabulations, mathematical and logistic regression analysis. The results of the analysis showed that there were differences in the performance of the socioeconomy of farmers adopting and not adopting. The performance of the socio-economic of farmers who adopt were better than farmers who did not adopt the technology CI 200. The factors that determine the farmers adopt were the age, education, origin, experience, income, and the cost of farming.
