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

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

Urban farming activities in Surabaya have continued to grow rapidly since the end of the COVID-19 pandemic in 2022, meeting approximately 20 percent of the city's vegetable needs. The improved skills of various vegetable cultivation groups, including the Barokah Farmers Group in Babat Jerawat Village, Pakal District, have led them to be named "Jawara". Armed with this achievement, they are attempting to expand into seasonal fruit farming using hydroponic technology under the shade of a screen house. On the other hand, Surabaya's hot weather and relatively high humidity are obstacles to implementing hydroponic cultivation systems in screenhouses. Exposure to intense sunlight during the day can increase the temperature of the pipes containing the net pots and nutrient reservoirs to 45°C, thus impacting the temperature of the AB Mix nutrient solution and the physiology of melon plant roots. Armed with experience from research and melon cultivation practices, the community service implementation team conducted a demonstration plot of superior hydroponic melon cultivation in a screenhouse. Based on the findings of the hydroponic installation research on campus, several modifications have been made to the hydroponic installation, including the addition of a cooling layer for the netpots and hydroponic nutrient reservoirs. The added heat insulation layer maintains the temperature of the piping and nutrient reservoir between 30-32°C. This is expected to allow the melon plants to grow normally without environmental stress until harvest, when they yield optimal fruit.

Abstract

The utilization of banana peels as a natural remedy for minor burn wound healing and antimicrobial activity has garnered increasing attention amidst the growing interest in plant-based traditional medicine. This study investigated the bioactive components present in banana peels, including flavonoids, tannins, and polyphenols, which contribute to wound healing and the prevention of infections. Conducted as a community engagement initiative in Jemur Wonosari Sub-district, Surabaya, the activity was designed to be replicable at the household level using simple tools and locally available materials. The preparation process involved cleaning the peels, heating them with virgin coconut oil, and optionally adding natural honey to enhance antibacterial properties. Findings highlight the potential of banana peels as an effective natural burn ointment with antimicrobial and antioxidant properties, while also supporting circular economy principles through the utilization of agricultural waste. Further research is needed to standardize formulations and clinically validate the widespread use of ointments based on banana peels.

Abstract

Ngadilegi Utara Hamlet is one of the hamlets of Plintahan Village, Pandaan District, which has great potential in the agricultural sector. However, global climate change has caused problems that Ngadilegi Utara farmers, especially the Madulegi Farmer Group, must face in cultivating crops. The impact of global climate change can trigger the emergence of plant pest organisms (OPT) which can affect the achievement of quality to meet market demand (consumers). Meanwhile, farmers in Ngadilegi Utara Hamlet still carry out crop cultivation activities on open land which is very potential for pest and disease attacks, and can be disrupted by environmental stress. Cultivation innovation using a screenhouse is one solution to overcome the problem in order to increase plant productivity. The screenhouse was built with a size of 6 x 8 meters using a hollow and galvanized C frame. The roof uses UV plastic with a thickness of 200 microns, the walls use insect net with a density of 50 mesh, and the base is covered using tarpaulin. The construction of the screenhouse in Ngadilegi Utara Hamlet is considered to reduce the attack of plant pest organisms (OPT) and environmental stress factors, so that farmer groups in Ngadilegi Utara Hamlet can increase crop productivity well.

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.
