The data that has been obtained is analyzed using the scoring or weighting method to determine the level of land suitability. Based on the calculations and analysis carried out on the evaluation of land suitability for settlements in the Gunung Sarik area, it can be concluded that the post-mining area in the Gunung Sarik area is suitable for settlements with a land suitability level value of 57 which with a land suitability level value of 58.7 - 37.4 is appropriate with details of 6 physical parameters that are met, namely, the level of slope 15.76%; Alluvial soil type, erosion hazard 348.83 tons/day/year, never flooded, fine soil texture (Clay), and has good soil bearing capacity (165 kg/cm 2 ).

PHYTIC ACID CONTENT IN BIOFORTIFIED RICE LINES AND ITS ASSOCIATION WITH MICRONUTRIENT CONTENT AND GRAIN YIELD OF RICE

Iron and zinc are essential micronutrients for human growth, development, and immune system maintenance. Iron (Fe) and zinc (Zn) are necessary for psychomotor development, sustained physical activity and work capacity, infection resistance, and various metabolic functions. Currently, rice, preferred for being high in Fe and Zn, is also a choice for being low in anti-nutritional compounds, namely, phytic acid. The presented study sought to identify the phytic acid content in several biofortified rice lines and determine the correlation of phytic acid with Fe and Zn content and yield characters. The research ran during the dry season (DS) from January to September 2022, with an alluvial soil type at the Sukamandi Experimental Station of ICRIST – Subang, West Java, Indonesia (altitude of 40 masl). Testing of 10 rice (Oryza sativa L.) genotypes comprising six BC4F3 biofortified rice lines for high Zn and four check cultivars (Inpari IR Nutri Zinc, Inpari 23, Ciherang, and Sintanur) used a randomized complete block design with three replications. Correlation analysis determined breeding strategies for high Zn/Fe rice with low phytic acid. The results revealed that phytic acid did not significantly correlate with Zn content, 1000-grain weight, and yield per plant. However, phytic acid had a strong positive correlation with Fe content. The rice line WR10 occurred as the best line because it had the highest Zn content (33.80 mg kg-1) and lower phytic acid and Zn ratio (PA: Zn) compared with all check cultivars, giving the highest yield potential and better yield than the Ciherang cultivar.

Growth And Production of Lowland Rice Due to Soil Ameliorant Application on Andosol, Mediterranean And Alluvial Soil

Lowland rice production and growth in Andosol, Mediterranean, and Alluvial soil types were observed in the study, both with and without amendments. The investigation was conducted using a plot experiment with a fully randomized design and three replications. L1: Andosol, L2: Mediterranean, and L3: Alluvial soil types made up the primary plots. Land amendments were divided into two subplots: R1 with no amendment and R2 with an amendment. Plant height, shoot and root dry weight, shoot:root ratio, and grain dry weight were the parameters measured. The findings demonstrated a significant (P<0.05) impact of the interaction effect of soil type amendment and bioslurry dose on the development and yield of three rice cultivars. Plant height, shoot dry weight, and grain dry weight with soil amendment were more significant (P<0.05) than without amendment, according to the interaction between soil type and amendment. The amendment application had little effect on the andosol soil. Alluvial soil types had the highest soil amendment response (P<0.05), followed by Mediterranean and Andosols. Based on the experimental findings, the soil enhancer formulation has been suggested for use in rice production, particularly in Mediterranean and Alluvial soils, although additional study is required to develop new formulations for Andosol soils.

Finding the optimum groin layout for the Konaweha river banks protection via 2D numerical modeling

River bank erosion has become a critical issue, especially for river bends with an alluvial soil type. Mostly, river bank erosions have caused structural failures because many national roads in Indonesia are placed near the river bend areas. Groins can reduce flow velocity, thereby increasing riverbank stability. However, most groins were installed in the river without impacting the river flow due to the improper design. This paper analyzes the use of groins placed at the river bend of the Konaweha River to protect the river bank with a length of 250 m from erosion. The evaluation employs 2D numerical modeling using MIKE21 FM to observe the influence of the groin on the river velocity, flow distribution pattern, and water level. Sixteen model scenarios with four groin configurations were tested for 25-year discharge, 2-year discharge, normal discharge 600 m3/s, and low discharge 197 m3/s to achieve the most effective plan. Based on the simulation results, Scenarios with five groins are recommended to reduce the flow velocity along the outer river bank from 2 to 0.3 m/s, thus minimizing the erosion. In addition, the spacing of groins being twice the groin length is recommended.

Floodplain soils on the soil map of the Russian Federation, scale 1 : 2.5 M, 1988, in the Russian soil classification

The development of the digital model of the soil map of Russia derived of the map of the Soviet Russian Federation, 1988, compiled in Dokuchaev Soil Science Institute, comprises the transfer of soil names in the initial legend to those in the new classification system of Russian soils (2004). Floodplain soils (only native) are represented by seven legend units (out of 205) that were named in terms of soil classification of USSR, 1977, and part of their names indicated ‘landscapes’ rather than soils, which disagrees with the principles of the new classification system. Basing on numerous publications and following the rules of the new system, soils were renamed. Most of them were referred to alluvial soil types within the synlithogenic trunk (Fluvisols), and their new names indicate both their properties and their zonal attachment. In order to obtain more adequate patterns of soils in river valleys additional soils were introduced including stratified-alluvial soils in the trunk of primary pedogenesis (Regosols). Simultaneously, the composition of polygons in the database was revised in accordance with regional data; human-modified soils were introduced (agro-soils and urbo-soils).

Agronomic character of several local genotypes of sorghum (Sorghum bicolor l.) at East Java

Sorghum classified as an annual crop that is very easy to be cultivated but its production until now classified as lagging compared to rice, corn and other cereals. In an effort to increase the fulfillment of food needs, sorghum plants can be developed in Indonesia as an alternative to local food other than rice. The development of sorghum plants is considered capable of supporting government programs to prevent the policy of importing rice and wheat.This study aims to determine the character of several genotypes of local sorghum East Java grown on paddy fields in Purutrejo Village, Purworejo Sub-District, Pasuruan City at an altitude of 5 m ASL with alluvial soil type. The average temperature is 29°C - 34°C with an average rainfall of 1430 mm / year. The study was conducted from June to August 2017. The experiments were arranged in a Randomized Block Design, using nine local sorghum genotypes replicated three times. Nine genotypes of local sorghum are Pasuruan, Lamongan 1, Lamongan 2, Tuban, Sampang 1, Sampang 2, Tulungagung 1, Tulungagung 2 and Jombang.The results showed that nine characterized genotypes had various agronomic characteristics on plant height, leaf number, stem diameter, panicle length, number of seeds per panicle, seed weight per panicle and 100 seed weight.

Subsidence analysis in DKI Jakarta using Differential Interferometry Synthetic Aperture Radar (DInSAR) Method

Land subsidence in DKI Jakarta influenced by several key factors, including the number of buildings that increase the load above the surface. There are still many people who explore groundwater sources as the principal source of clean water. Also, the soil type is dominated by alluvial. This alluvial deposit can be one of the parameters for soil deformation in the form of land subsidence and uplift in land surface because basically, alluvial soil types have a susceptibility to the load support power above. So that the land subsidence in DKI Jakarta is relatively continuous. To find out the land subsidence is used a high-tech method, Differential Interferometry Synthetic Aperture Radar (DInSAR) satellite image of radar data (SAR Sentinel-1A) in 2017. The result shows the land subsidence in the average value of DKI Jakarta which is about -3.685 cm/year and the highest subsidence happened in the West Jakarta district about -5.850 cm/year in average.

Characterization of fava bean (Vicia faba L.) genotypes for phytoremediation of cadmium and lead co-contaminated soils coupled with agro-production

The identification of high yield genotypes that are capable of accumulating multiple heavy metals in the non-edible parts (roots and shoots), but not in the edible parts (seeds) and have desired nutritional value is necessary for accomplishing phytoremediation coupled with agro-production. In this study, 17 fava bean genotypes were screened in two different field conditions to examine their phytoremediation potential in terms of uptake and translocation of Cd and Pb. Ten genotypes, LBAO, JNJX, DCAN, QXCJ, QIKM, LXYC, YDL6, RBCD, QPID and ZHW6 were found as the best accumulators for Cd and Pb with permissible limit of metals in seeds. The concentration of plant nutrients were genotype and soil type dependent and there was a significant correlation between these two factors. Furthermore, the three genotypes DCAN, LBAO and LXYC showed best performance in alluvial soil type while QPID, RBCD and LXYC were the best in red soil type. Genotype LXYC was similar for both soil types and appeared to be the best fit for phytoremediation coupled with agro-production for slightly or moderately Cd and Pb co-contaminated soil. Therefore, fava bean LXYC genotype is suggested as a potential candidate for phytoremediation of Cd/Pb co-contaminated soils coupled with agro-production.
