Abstract

Susilawati et al, 2019.The Effect of Using Growing Media Composition on Growth and Yield of Shallot (Allium cepa L.). pp. 93-102.The aimed of research was to study the effect of using growing media composition on growth and yield of shallot (Allium cepa L.). Research was conducted from February until April 2017. Design used in this study was randomized block design (RBD) with 9 treatments and 3 replications. The treatments was A0 = Control (90% soil : 10% chicken manure), A1 = 80% soil : 20% cow manure, A2 : 70% soil : 30% cow manure, A3 = 60%  soil : 40% cow manure, A4 = 50% soil : 50% cow manure , A5 = 80% soil : 20% husk charcoal, A6 = 70% soil : 30% husk charcoal, A7 = 60% soil : 40%  husk charcoal, A8 = 50% soil : 50 husk charcoal. The results showed that the use of planting media composition of 60% soil : 40% of cow manure can improve the growth and yield of shallot plants better. This is consistent with plant height variables, number of leaves, number of tillers, number of tubers, fresh weight of tubers, and dry weight of tubers. The highest dry weight yield was found in the composition of 60% soil : 40% of cow manure with an average yield of 84.36 g per hill.

Abstract

Priatna et al, 2019. Land Quality Improvement Through the Utilization of Palm Oil Waste (Study Case of PT. Waimusi Agroindah Palm Oil Plantation). pp. 421-429.Oil palm plantations are one of the natural resource-based businesses that have strategic roles and contributions to the Indonesian economy. Increasing the development of the oil palm plantation sector needs to be balanced with a good environmental management, control and preservation system. The application of clean technology is one part of sustainable and environmentally friendly development that needs to be applied in the stages of waste management. This research activity aimed to determine the effect of palm oil liquid waste utilization (LCPKS) on the quality of land in oil palm plantations of PT. Waimusi Agroindah, Mesuji Raya District, Ogan Ilir Regency, South Sumatra. The dose of LCPKS utilized was 218.77 m3 / ha / year from the 8th pool (aerobic pond) which was transported using a 15,000 liter capacity tank to the study block. The distribution of LCPKS in the study block was carried out by longbed measuring 2.5 x 1.5 x 0.25 m which was interconnected with a small ditch in a row. The block used as a comparison (control block) was only given conventional fertilizer N, P and K without LCPKS. Changes in land quality were assessed by observing soil properties in 6 layers with a depth of 20 cm in each layer and through crop productivity data. The results showed that in general the conditions of soil properties (pH, organic C, N-total P available, K-dd and elements Na, Ca and Mg) experienced an increase that could be seen up to a depth of 40 cm. The element that experienced the most increase was the element P, whereas in the N and K elements the increase that occurred was not too significant. Based on productivity data, oil palm plants in the study locations have higher TBS harvests compared to control locations. The increase in plant productivity in the study area increased by an average of 22.01% when compared to control land that was not applied by LCPKS. LCPKS utilization activities on land are considered to have a positive impact, provided that N and K fertilizers are still needed to further optimize plant growth & productivity.

Abstract

Nurfitriani et al, 2019. Mercury Accumulation Ability of Bacteria Isolated from Small-Scale Gold Mine Tailing. pp. 366-375. Heavy metal pollution in the soil due to small-scale gold mining activities (ASGM) is responsible for 37% of mercury (Hg) pollution to the environment in the form of tailings . This pollution causes mercury enrichment  in agricultural land and crops above the safe limits. This study aimed to isolate heterotrophic bacteria which can  accumulate mercury from small-scale gold minetailings in Sekotong District, West Lombok. In this study, mercury resistant bacteria were obtained through a series of on Nutrient Agar medium. The obtained isolates were identified based on the colony morphology (the Bergey Manual Determinative system), gram staining test, biochemical test and growth curve test. Hg accumulation ability test was carried out on liquid Nutrient Broth (NB) medium containing 50 mL + HgCl2( 10 ppm, 20 ppm, and 30 ppm). The ability of isolates to accumulate Hg was also tested on gold mine tailings with an incubation method for 4 weeks. The results showed that four isolates of mercury-resistant bacteria were isolated, namely Brevundimonasvesicularis, Nitrococcusmobilis, Fusobacterium aquatile, and Fusobacterium necrogenes. Two of four isolates obtained, Fusobacterium aquatile and Brevundimonasvesicularis, could accumulate Hg highest in tailing medium.Brevundimonasvesicularis had the highest Hg accumulation ability which was approximately 1.68, 2.08, and 2.17 ppm Hg at 10, 20, and 30 ppm Hg treatment, respectively. Based on this study, Fusobacterium aquatile and Brevundimonasvesicularis have the potential to be used in bioremediation of soil contaminated with mercury.
