Abstract

Brown rice local cultivars are found in West Nusa Tenggara, but brown rice is still very rare to be used as a source of genetic diversity and its improvement is also lacking to be considered. This research aims to determine the effect of 300 Gy gamma ray irradiation on the quantitative properties of third generation G16 brown rice (M3) in the uplands. In this research, an experimental method was used with field experiments from May to December 2022 in Tatar Hamlet, Nyurlembang Village, Narmada District, West Lombok Regency. This research used Randomized Block Design (RBD) in an Augmented design with 18 treatments consisting of 15 G16 mutant strains and 3 comparison plants. The data obtained were analyzed using Analysis of Variance (Anova) with a level of 5%, then the real different treatment was further tested using the Least Significance Different (LSD) test. Based on the results of the research, it was obtained that some of the quantitative traits observed did not have differences in the properties of the elders and their comparators. The morphological apperance of mutant plants is the same as that of both the elders and the comparison varieties. However, it can be said that all strains based on their morphological appearance have the potential to be developed on dry land, because all strains tested show the same results compared to their elders and peers.

Abstract

Dryland is defined as land that is never flooded or submerged in water throughout the year. Indonesia has a very large area of dryland, which is 11,876,881 hectares. Generally, drylands have low fertility and thin soil layers with low organic matter content. There are several types of plants that can be cultivated in drylands, one of which is tobacco. Environmental conditions such as soil conditions (physical and chemical properties of soil) affect the production and quality of tobacco, among others, soil status. In this topic, the descriptive method was used as an approach. Data collection techniques (literature) were carried out using books, articles, and scientific journals derived from previous research. It was concluded that an increase in C-organic content, CEC, and KB increased tobacco production. Conversely, an increase in pH can adversely affect tobacco production and quality.

Abstract

Organic matter is one of the important factors that can determine the level of soil fertility and health. The presence of organic matter in the soil is currently quite worrying. This is due to the behavior of the farmers themselves who tend to carry out inappropriate cultivation and the excessive use of inorganic fertilizers and the use of chemical pesticides that exceed the dosage. It is necessary to take appropriate measures so that the organic matter in the soil is not reduced. The analysis was carried out descriptively by conducting a literature study on relevant literature and conducting a qualitative analysis. Based on the results of a review of international and national journals that cover crops can play an active role in the growth rate and yield of cultivated plants. Ground cover plants can be used as conservation plants, soil health and fertility and the environment as erosion control, maintaining soil moisture, controlling pest populations, suppressing weed growth. The advice that can be given from this paper is the need for further research on the use of cover crops as a source of organic matter in soil balance and agro-ecosystems.

Abstract

The potential of dry land for agricultural development in Indonesia is very large, one way that can be done to increase soil fertility and productivity of dry land is by using PGPR biologival fertilizers and various planting media such as husk charcoal and cocopeat. The purpose of this writing is to determine the effect of giving Plant Growth Promoting Rhizobacteria and various planting media on soil fertility in dry land. This research was conducted using a descriptive method by obtaining data from publication in the form of research journal, review journal published in international and national journals and other related information. Descriptive analysis was carried out by means of 1). Do a search of appropriate literature 2). Screening and selecting relevant articles 3). Conducting qualitative analysis and 4). Compile articles. The application of PGPR and various planting media can increase the physical and chemical fertility of the soil and nutrient absorption for the soil, such as improving soil ph, organic C, P-total and soil N-total. The mechanism of PGPR to increase soil fertility is by fixing nitrogen in the air with the help of the enzyme nitogenase, as a phosphate solvent, and as a producer of plant hormones.

Abstract

Indonesia has abundant natural resources. One of the great natural resources is mineral resources in the form of gold. With this potential, the number of national mining locations continues to increase, both large, medium, small and unlicensed gold mining (PETI) carried out directly by the community, either in groups or individually, which can have a negative impact on the environment. pollution such as land and water. , because the results of gold processing which contain heavy metals (Hg) are immediately thrown away without any further processing. This can harm the surrounding environment and even enter the food chain. Therefore, the purpose of this paper is to study and find out related information regarding the effectiveness of phytoremediation of soil contaminated with heavy metals such as mercury (Hg) using vetiver (Vetiveria zizanoides L.) and soil ameliorant materials in the form of rice husks. biochar to reduce the concentration of these heavy metals, as well as the mechanisms involved in phytoremediation of soil contaminated with heavy metals. The vetiver root plant (Vetiveria zizanoides L) is very effective for use in remediating soil contaminated with mercury (Hg) or other heavy metals. The use of biochar can influence the growth and absorption of heavy metals by vetiver (Vetiveria zizanoides L). Biochar is also able to improve the physical and chemical properties of soil and stabilize heavy metals in the soil.

Abstract

: The dangers of mercury in nature cause negative impacts on the environment and humans. The nature of mercury is bioaccumulative and toxic, and it cannot be degraded quickly but only through valence transformation. One effort that can be made to reduce the level of toxicity from mercury is to use biochar as an adsorbent agent in the soil. This article's goal is to review data regarding the use of biological charcoal (biochar) as a soil adsorbent for mercury. In order to clean up soil that has been contaminated with mercury (Hg), rice husk biochar plays a crucial function. Other than that, by using these organic materials instead of synthetic ones, soil production can be increased while environmental impact is reduced by 56%. Mercury is absorbed by biochar through a number of different mechanisms, including: (1) electrostatic bonds; (2) K+ and Na+ with Hg2+ and Hg+ ions simultaneously; (3) covalent reduction of mercury from Hg2+ to Hg+ and Hg0; (4) formation of a mineral complex (Hg2(OH)2) through precipitation of Hg2+ with carboxyl groups, such as lactones; and (5) complexation reactions on oxygen-containing functional groups such as - In comparison to soil alone, the use of biochar along with other organic elements can boost the capacity of heavy metal adsorption. With this combination, mercury levels were reduced to 12.45 ppm while soil pH increased dramatically from 0.3 to 1.33 units, near to neutral.

Abstract

One of the hazardous wastes generated from unlicensed gold mining is mercury. Mercury is a toxic metal that can have a negative impact on the environment such as reducing soil and water quality and disturbing human health. The presence of mercury in the soil is completely controlled by adsorption-desorption of various sorbents. Soil properties greatly affect the adsorption and desorption of mercury in the soil. Because different soil properties will adsorb and desorb mercury in different ways and amounts.  The purpose of writing this article is to review the results of previous research on the adsorption-desorption of mercury in soil so as to determine the extent of the risk of soil and environmental pollution. The method used in this writing is to collect and process data sources from previous research published in scientific articles, books, and discussion results. The results show that soils with high organic matter, iron oxide and clay content can absorb more Hg2+. In addition, lower pH has more hydroxylated surfaces that can adsorb more Hg2+. Irreversibility was found where the amount released or desorbed was less than the adsorption of mercury.
