Abstract

This study aimed to determine the efficacy of several varieties of maize at various rate of manure under drought condition on the dry land of North Lombok. The experiments were designed using split plot design, with manure rates (0, 5, 10, 15 and 20 t.ha-1) as the main plots, and five different maize varieties (P4IS, Gumarang, Lamuru, Sukmaraga and NK212 Hybrid) as subplots. The efficacy of several maize varieties were determined from the weight of dry seeds per plant. Experimental data were analyzed using analysis of variance (ANOVA) at 5 percent significant levels. The mean of each treatments was further tested using the Honestly Significant Difference (HSD) at the same level. The results showed that the highest yield of maize crop was obtained on Lamuru variety at rate of manure of 20 t/ha, ie 85.94 g.plant-1 or 6.14 t.ha-1. The yield of Lamuru variety is similar to that of Sukmaraga, but it is higher compared to P4IS, Gumarang and Hybrid of NK212.The highest yield of maize crop was obtained at rate of manureof 20t.ha-1.

Abstract

Agricultural land in North Lombok is dominated by a typology of sub-optimal land, physically, chemically and biologically. These properties make it vulnerable to degradation. In such land, agroforestry system is highly recommended, where the porang plant can be included as a component. Nowdays, porang is gaining popularity as a commodity with economic value, and is suitable as an intercropping plant. It is easy to grow on almost all types of soil, and is resistant to shade, making it adaptive to agroforestry systems as non-timber under standing plants in community forest systems. It is believed that this will provide multiple benefits economicly and environmentaly, if it accompanied by the principles of soil and water conservation. The role of porang as a conservative agent has been investigated through a scientific approach as the basis for the domistication of porang in agroforestry systems. The results showed that agroforestry with porang could help improve the stability of the soil aggregates as indicated by the soil aggregate stability index 59 which means rather stable. Soil moisture of wilting point in agroforestry system with porang increased from 3.0% (without porang) to 5.4%. In addition, the soil organic matter content increased to 3.94% (quite high) on the system with porang because the stems and leaves of porang plant are quickly weathered. The ground cover is relatively tight, so it can prevent soil erosion. Porang also play a role in increasing water infiltration due to the presence of porang’s roots and tubers. Thus the domistication of porang fulfills the requirements as an agent of soil conservation, as non-timber plant in the agroforestry system, if it is cultivated according to the principles of soil and water conservation on the typology of sub-optimal land in North Lombok.

Abstract

One of the tourist destinations in Lombok, West Nusa Tenggara is the Special Economic Zone Mandalika (KEK Mandalika), a coastal tourism area with various supporting infrastructures on an international scale covering an area of 1,035.67 hectares. The pace of development brings environmental impacts, especially the morphology of the land in the form of mountains and hills is exposed by the conversion of land functions from proteced forest to agricultural areas without the application of land conservation methods. Bypass BIL-KEK Mandalika as the main connecting road for this tourism area is 17.2 km long flanked by hills with a slope of >30o and almost all hilly areas have been converted into agricultural areas. In this area there is minimal standing vegetation accompanied by unstable physical conditions, making all hilly areas on the BIL-KEK Madalika bypass classified as a Very High Erosion Hazard Level which reaches > 560 tons/ha/year which triggers more potential hazards. big like landslides and floods. Various steps have been taken, such as: 1) Integration of porang (Amorphopallus) and standing vegetation (canopy) applied in hilly areas in the Bypass BIL-KEK Mandalika area; 2) Emphasizing and preventing the conversion of buffer zones; 3) Rehabilitation of the Bypass BIL-KEK Mandalika Hills Area.

Abstract

This study aims to determine the effect of biochar application on Hg mobility in a closed leaching experiment using gold processing tailings contaminated soil. The factorial experiment was set up using a Completely Randomized Design (RBD) which tested three types of biochar (rice husk biochar, coconut shell, and corncob biochar) and three doses of biochar (0.10 tons ha-1 and 15 tons ha-1). The PVC column containing a mixture of polluted soil and dibiochar was washed four times with deionized water for a total of 1090 ml of watering. The results showed that the application of biochar can reduce the mobility of mercury (Hg) in small scale gold processing tailings polluted soils. The dissolved Hg concentration in the leachate decreased with increasing dose of biochar application. Leachate from corn cob biochar (15 tons ha-1) treatment showed the lowest Hg concentration of 0.0012 ppm but was not significantly different from leachate from the soil column that was applied coconut shell and rice husk biochar. The concentration of Hg in the leachate for all biochar treatments ranged from 0.0012 - 0.0062 ppm, significantly different from the leachate concentration of the soil column without biochar, which was 1.62 ppm. This provides an indication that biochar can reduce the leaching rate, so that the concentration of Hg is not much leached into the soil. Therefore, biochar can be used as a soil enhancer in remediation of mercury (Hg) polluted soil so that it can slow down the mobility of mercury (Hg) so that it has a small impact on the environment.

Abstract

This study aims to determine the potential of biochar on the mobility of mercury (Hg) in polluted soil planted with mustard greens (Brasicca juncea) and to determine the growth response of mustard greens (Brasicca juncea) in absorbing mercury (Hg). This study used the experimental method, which is a method that aims to examine the effect of biochar application at various doses on the mobility of mercury using the indicator plant mustard greens (Brasicca juncea L) in mercury (Hg) polluted soil. This experiment was carried out from March to June 2023 in the Greenhouse of the Faculty of Agriculture, University of Mataram. Soil samples were collected in Pelangan Village, Sekotong District, West Lombok Regency at several points near the gold processing unit. The samples were taken at top soil of 30 cm with a distance of 100 cm from the processing site then composited. Soilschemical properties including concentration of Hg before and after experiments were measured. Agronomic variables include fresh and dry weight of roots, total dry weight of and concentration of Hg) in plant tissue were also measured. The results of the study showed that the application of rice biochar reduced mobility of Hg in soils. The concentration of extractable-Hg in biochar-treated soils were lower compared to control. This is likely related to the potential adsorption of a number of IHg and MeHg by the negative surface of the biochar and also the formation of association of Hg bonds with the functional groups of the biochar. However, this needs further confirmation.
