Abstract

Ultisols has an advanced degree of development, characterized by deep profil, increase of clay fraction along with the depth of soil, soil acidity, and low base saturation. Low pH, low nutrient elements such as nitrogen, phosphor, and potassium, low availability of organic carbon, Ca, Mg, Na, cation exchange capacity (CEC), base saturation are the characteristic of post bauxite mining land. The land that was formerly bauxite mining process by removing of a layer of top soil until the layer that contains the seeds of bauxite called post bauxite mining land. Coastal sediment is sediment which contains quite high micro nutrients with low CEC so by the addition of coastal sediment expected to increase base saturation and soil fertility. Cow manure is one of the alternative to improve the fertility of the soil. This study get analyzed by Complete Randomize Design (CRD) consisting of 4 treatments and 5 replications. A Treatment (control), B treatment (1.5 kg coastal sediment + 2.5 kg of manure), C treatment (2.4 kg coastal sediment + 4 kg of manure), the last D treatment (3.3 kg coastal sediment + manure). This research analyzed with the F test, if significant continued with Tukey’s Honestly Significant Difference (HSD) at the 5% level to obtain the difference between treatments. Based on the result, combination of Coastal sediment and cow manure from the C treatment (2.4 kg coastal sediment + 4 kg manure) able to increase pH of soil up to 6.68, which is the highest pH among the other treatments. Keywords : Ultisols, coastal sediment, cow manure, bauxite mining.

Abstract

The use of a single herbicide often cannot control all types of weeds. Increase the effects of weed control. This study aims to study the effectiveness of glyphosate and methyl metsulfuron herbicides to control the Ischaemum timorense weed and determine the nature of the mixture. This research was conducted from January to April 2019, for ± 4 months in the greenhouse and Pesticide Laboratory of the Faculty of Agriculture, Tanjungpura University, Pontianak. The research was arranged in random groups. The treatment consisted of 4 types of herbicides with five dose levels and 1 control, namely glyphosate (0, 0.188, 0.375, 0.750, 1.5, 3.0) l / ha, methyl metsulfuron (0, 10, 20, 40, 80, 160) g / ha, herbicide mixture A 240/10 SL (0, 0.25, 0.50, 1.00 2.00, 4.00) l / ha and mixed herbicide B 360/10 SL (0, 0 , 25, 0.50, 1.00, 2.00, 4.00) l / ha. The target weed is Ischaemum timorense, a grass weed which is planted in a 14 cm diameter pot and a target of 3 MST (Three weeks after planting a herbicide test is applied). The variables observed are the level of weed damage that was assessed through phytotoxicity scoring and weed dry weights and analysis of herbicide mixture properties. The results showed that the higher the dose of the herbicide that was given, the more effective the suppressor was in controlling weeds. Herbicides that have been able to restore weed growth include glyphosate (G3) at a dose of 0.750 l / ha, Methyl metsulfuron (M5) at a dose of 160 g / ha, A mixture of 240/10 SL (CG3) at a dose of 1.0 l / ha , Mixture B 360/10 SL (CB3) at a dose of 1.0 l / ha. A mixed herbicide A 240/10 SL with an LD50 value of 93.2 and a mixture of B 360/10 SL is 186.92 smaller than the LD50 value of a single glyphosate herbicide 186.83 and methyl metsulfuron 27.98. The index value of combination herbicide mixture A 240/10 SL is 1.0384 and herbicide mixture B 360/10 SL is 1.0262, thus the nature of the herbicide is not antagonistic.Keywords: Glyphosate, Methyl metsulfuron, LD50, Herbicide mixture.

Abstract

Sambal lime juice is one of the marinated ingredients that contain citric acid that have the function of preserving the quality of broiler meat. This research aimed to determine the quality of broiler meat marinated using sambal lime (Citrus microcarpa) juice with different concentrations and the immersion durations. The materials of this research were 24 pieces of broiler meat breasts. This research has used the factorial, completely randomized design (CRD). The first factor was the concentrations and the second factor was immersion durations of sambal lime, with the treatment combination were: 10%;10 minutes (K1L1), 10%;20 minutes (K1L2), 10%;30 minutes (K1L3), 20%;10 minutes (K2L1), 20%;20 minutes (K2L2), dan 20%;30 minutes (K2L3) with four replicated. The observed variables were the pH, protein content and water holding capacity. The results showed that the quality of broiler meat marinated using sambal lime juice, with different concentrations, did not affect all variables. However, the different immersion duration had a very significant effect on the pH value (4,67-5.47) and did not influence on protein content (21.38-22.54%) and water holding capacity (65.50-69.50%). The conclusion of this research is the best treatment of marinating using sambal lime juice on broiler meat quality is a concentration of 10% with an immersion duration of 20 minutes.
