Abstract

Contamination of heavy metal including Arsenic (As) due to mining activities decreased ecosystem quality. The objective of this study was to determine the arsenic level of tailing and agricultural soil, and evaluate the spatial distribution of As in closed gold mine and nearby agricultural area in Buru Sub-district of Maluku. Tailing and soil samples were taken by purposive method based on mining and agricultural activities. Arsenic level in tailing and soil samples was determined by Atomic Adsorption Spectrophotometer after mixed acid extraction. The study showed that gold mine increased As level in the top soil and tailing but soil of nearby agricultural area was not contaminated by As. Increased concentration of As in tailings has been verified. pH level of the agricultural area was neutral hence lowered As availability for plant.

Abstract

In the past decade, Indonesian interest towards sweet corn has increased. This condition creates a wide market opportunity for sweet corn. However, sweet corn cultivation in Indonesia is often constrained by low soil fertility. One of the essential nutrients needed by sweet corn is nitrogen. Nitrogen can be obtained from inorganic fertilizers such as Ammonium Chloride (NH4Cl) fertilizer. This research aimed to determine the effect and the best dosage of Ammonium Chloride (NH4Cl) in increasing N-total, N uptake, and yield of Sweet Corn (Zea mays saccharata Sturt) of Talenta variety on Jatinangor Inceptisol. This experiment was conducted at the research field of Soil Chemistry and Plant Nutrition, Department of Soil Science and Land Resources, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor from July to October 2020. The experimental design used in this research was Randomized Block Design (RDB), which consisted of nine treatments with 1 control treatment (without fertilizer), 1 standard single N, P, K fertilizer treatment, 3 dosages of Ammonium Chloride (NH4Cl) fertilizer treatment, and 4 combinations of Ammonium Chloride (NH4Cl) fertilizer with ¾ recommended dose of standard N, P, K fertilizer. The results showed that the combination of Ammonium Chloride (NH4Cl) fertilizer affected the total Nitrogen content, nitrogen uptake, and yield of sweet corn. Combination of 1 ¼ dose of Ammonium Chloride (NH4Cl) fertilizer with ¾ recommended dose of standard N, P, K fertilizer show the highest increase in total nitrogen (0,24%), nitrogen uptake (2,72 g per plant), and fresh weight of the corn cobs (0,42 kg per plant).

Abstract

Hydroponic system is an alternative agricultural cultivation technology and a potential system to overcome the decreasing availability of land. Tomato production with this system has its own market segment. Balanced nutrient management combined with inoculation of functional microbial consortium (N-fixing bacteria and phosphate solubilizers) is one of the efforts to increase tomato production in a hydroponic system. This experiment aimed to examine the effect of microbial consortium and hydroponic nutrition on tomato plant growth, Azotobacter spp. population, N uptake and tomato yield. The research design used was a factorial randomized block design (RBD) consisted of two factors. The first factor was the dose of the microbial consortium, consisting of three levels (0 mL/polybag, 5 mL/polybag, and 10 mL/polybag. The second factor was the nutritional dose consisting of three levels (0 mL, 250 mL, and 500 mL). The experimental results showed that there was no interaction between the microbial consortium treatment nutrients on hydroponic plants’ height, N uptake, Azotobacter spp. population and tomato yield. Increased nutrient dose significantly increased N uptake, with the highest yield at 500 ml/pot. But the increased nutrients dose did not lead to significantly different tomato yields. Inoculation of the microbial consortium did not significantly increase all tested parameters.

Abstract

The process of refining iron by Blast Furnace (BF) or Electric Arc Furnace (EAF) produces steel and by-product: steel slag. This by-product can be used for various fields such as construction, industry and agriculture. This paper aimed to discuss the use of steel slag in agriculture as fertilizer, lime and ameliorant in the soils. The content of elements and compounds in steel slag is the basic component for the utilization of this material, therefore they are displayed quite completely. The presence of other contents like of heavy metals which are classified as hazardous toxic materials is also stated. Utilization of steel slag for agriculture has been carried out widely in various countries such as Japan, Germany and the United States. There have been many studies of steel slag in Indonesia that prove the benefits of steel slag in adding nutrients and improving soil reactions. However, the use of this material is still limited to research field, has not been widely used. Meanwhile, many research has proven that steel slag can improve some chemical characteristics like pH and CEC, as well improve Ca, Mg and Si content. Steel slag can release P from retention and fixation and Andisols and Ultisols. Research showed that steel slag improved the yield of rice, maize, horticultural and industrial plants.

Abstract

The development of rubber plantation in Sintang District continues to increase anually. Consequently, it is necessary to prepare a good rubber tiller. A Good rubber tiller can be obtained with the application of growth regulator when the tillers are ready to be planted. This study aimed to determine the effect of giving growth regulator Rootone-F on the growth of natural rubber saplings and to obtain a dose of Rootone-F growth regulator with the highest growth of natural rubber saplings.This study used a Randomized Block Design method, with one treatment (Rootone-F growth of regulator), consisted of 5 treatment levels: r0 = 0g Rootone-F per liter of water (control), r1 = 1g Rootone-F per liter of water, r2 = 2g Rootone-F per liter of water, r3 = 3g Rootone-F per liter of water, r4 = 4g Rootone-F per liter of water. Each treatment was repeated 4 times. Observations were made on these variables: plant height, leaves count, and stem diameter. The results showed that the Rootone-F growth regulator had the effect on the growth of natural rubber saplings. Highest growth was achieved at the dose of 2 g Rootone-F per liter of water, and based on the result of that dose there was an average increase in plant height (8.88 cm) and an average number of leaves (4.78 leaves).
