Abstract

Mangroves have ecological functions, one of which is being able to absorb and accumulate heavy metals which can pollute the environment. The aim of the research is to assess the ability of mangroves to accumulate the heavy metal Cu. The research location is on the East Surabaya River Coast. The research method is purposive sampling with a distance of 250 m from one point to another. The pH value is classified as neutral to slightly alkaline. The salinity value is classified as very high. The texture of mangrove sediments has fine particles consisting of clay and dust. Cu concentrations in sediments are still below quality standards according to the United States Environmental Protection Agency (US-EPA). The Cu concentration in the sediment was highest in the Tambak Oso River with an average of 50.50 mg/kg. The concentration of heavy metals in the roots is higher than in the leaves. The bioconcentration factor (BCF) value is classified as the excluder, while the translocation factor value is classified as the phytostabilization and phytoextraction classes. Keywords: Estuaries, Mangroves, Pollution, East surabaya, Cu toxicity.

Abstract

Land is an important part of the watershed because it is where the hydrological process occurs. There are several problems that can lead to land damage, especially in the downstream area of the watershed, precisely in the Manten Sub-watershed because it has the potential to become critical land. Therefore, this research was conducted with the aim to overcome the existing problems, it is necessary to identify the standard of land degradation in the Manten Sub-Watershed area in accordance with PP No. 150 of 2002. Manten sub-watershed covers 4 sub-districts namely Wajak, Poncokusumo, Tajinan, and Bululawang. Land use in Manten sub-watershed is divided into 3, namely rice fields, kailyards and fields. Based on the results of the analysis of all land use in Manten Sub Watershed, all parameters that have been observed do not exceed the critical threshold criteria except for the redox parameter has a very low value of <200mV. However, this condition can still be improved with proper management such as improving soil aeration using the addition of organic materials so as to increase oxygen levels in the soil and increase redox values.

Abstract

Soil erodibility is an important factor in determining soil loss. The objective of this study was to evaluate the soil erodibility value based on the Wischmeier-Smith Method. The study was carried out in Jatiarjo Village, Prigen District, Pasuruan Regency, at four land use units (LUU), including Mounts (MO), Mixed Garden (MI), Monoculture Garden (MG), and Shrubs (SR). Wischmeier-Smith algorithm was used to determine the erodibility values and classification. Results showed that shrub was identified as the land use with the highest potential for erosion and erodibility value. The correlation between clay fraction and erodibility has a negative value wit r = -0.76, while other fractions had r value < 0.5. This implied that the clay fraction and soil erodibility have an inverse relationship, where each increase in the clay fraction value will be followed by a decrease in the erodibility value. One way to reduce soil erodibility is to increase plant diversity on the land. Apart from adding organic matter, a variety of plants also have roots that are able to bind soil aggregates and help absorb water into the soil, thereby reducing water flow on the surface. If conservation is not taken seriously, it can undoubtedly result in.

Abstract

Soil salinity can damage soil structure due to its high sodium chloride content, leading to soil erosion and reduced aeration, which decreases the ability of plants to absorb water and inhibits plant growth. One approach to overcome this problem is by improving the chemical properties of saline soil; therefore, research on the application of arbuscular mycorrhizal fungi and manure is needed. This study aimed to determine whether the addition of manure and arbuscular mycorrhizal fungi at appropriate rates could improve the chemical properties of saline soil. A completely randomized design (CRD) with two factors was used, in which the first factor was the dose of arbuscular mycorrhizal fungi with four levels and the second factor was manure application with two levels, each repeated three times, resulting in eight treatments and 24 experimental units. The results showed that although the application of mycorrhizal fungi and manure did not significantly affect soil pH or electrical conductivity (EC), a single factor manure treatment increased soil pH and reduced EC values, while a single factor treatment of arbuscular mycorrhizal fungi reduced soil EC values. The combined application of manure and arbuscular mycorrhizal fungi significantly increased N-available (NH₄⁺ and NO₃⁻) during the first week after the application of 20 ton/ha of manure and 105 CFU/mL of arbuscular mycorrhizal fungi (M1K1).

Abstract

Market demand for cardamom (Elettaria cardamomum) continues to rise, yet its cultivation remains limited to specific regions with suitable environmental conditions. Therefore, land suitability evaluation is essential as a basis for planning the development of this commodity. This study aims to assess land suitability for cardamom cultivation in Sumber Rejo Village, Purwosari Subdistrict, Pasuruan Regency. The evaluation was based on physical and chemical soil properties, including pH, organic carbon (C-organic), cation exchange capacity (CEC), base saturation, as well as soil texture and slope. Samples were collected from two types of land use: dry land (tegalan) and coffee plantations, with a total of six sampling points. The results showed that soil pH ranged from 5.70 to 5.92 (S1), C-organic ranged from 1.61% to 2.79% (S1), CEC from 23.93 to 33.07 cmol/kg (S1), and base saturation was in average < 35% (S2). Overall, the study area falls into the moderately suitable (S2) category for cardamom cultivation with potential improvement to S1 through manure and compost application. This evaluation, however, was based on only four parameters so that future research should continue with other parameters to have a more comprehensive results on land suitability for cardamom cultivation in Sumber Rejo village.

Abstract

Soil contamination by heavy metals poses a significant threat to sustainable agriculture, especially in areas adjacent to industrial zones. This study demonstrates that while the initial application of the biosilica-humic acid (BSi-HA) soil amendment did not result in statistically significant changes in soil chemical properties within the first 7 days of incubation, prolonged incubation for 60 days revealed meaningful effects, particularly in reducing heavy metal availability in soil. Significant decreases in iron (Fe) and lead (Pb) concentrations were observed over time, with Fe reductions ranging from 45–67% and Pb reductions between 8–40%. These results are attributed to the synergistic effect of functional groups in BSi-HA—especially the carboxyl (–COOH) and hydroxyl (–OH) groups in humic acid—which exhibit high metal-binding affinity under acidic conditions (pH ~5). Although soil fertility parameters such as C-organic content and cation exchange capacity (CEC) showed a declining trend due to microbial activity during incubation, the ability of BSi-HA to immobilize heavy metals without exceeding safe thresholds highlights its potential as a sustainable soil amendment. Moreover, previous findings indicating reductions of up to 90% for Pb and 76% for Cd in plant tissues further support the efficacy of BSi-HA in mitigating heavy metal contamination in agricultural soils near industrial zones. Further long-term studies are recommended to evaluate BSi-HA's remediation capacity, persistence, and impact on crop yield and food safety. Combining biosilica and humic acid offers a promising, eco-friendly approach for managing heavy metal contamination in soils.

Abstract

Environmental factors, particularly salinity conditions, influence the function of mangrove forests. Salinity plays a crucial role in the growth, resilience, and zonation of mangrove species. Therefore, it is essential to analyze salinity levels. This study aims to assess salinity levels to determine their effect on soil fertility and to evaluate the influence of the distance from salinity sources in the Wonorejo Mangrove area. Soil sampling was conducted at distances ranging from 5 meters to 60 meters from the riverbank, along three designated paths: J1 (first path), J2 (second path), and J3 (third path). Both composite and intact soil samples were collected. Composite and intact soil samples were taken at intervals from 5 to 60 meters from the riverbank, with each path containing two sampling points, resulting in a total of six sample points (T1, T2, T3, T4, T5, T6), each repeated three times. The observed parameters included soil pH, electrical conductivity (EC), soil permeability, soil texture, cation exchange capacity, and organic carbon content. The results of the chemical and physical analyses of the mangrove forest soil samples indicate that salinity levels range from high to very high. This finding is evidenced by the lowest EC value recorded in soil sample T3U3, which was 15.9 dS/m, indicating high salinity.
