The utilization of clam shells as adsorbents has attracted considerable attention due to their ability to adsorb contaminants such as heavy metals, hazardous substances, and oil. Clam shells, which are composed mainly of calcium carbonate (CaCO₃), possess a porous structure that favors adsorption. Calcium carbonate imparts alkaline properties that neutralize acidic effluents and promote the formation of precipitates. Physical and chemical modifications can enhance the surface area and porosity of the shell, thereby enlarging the active sites for contaminant sorption. Clam shells heavy metals such as Pb, Cd, Hg, organic substances and can be used for oil spill remediation due to their hydrophobic and oleophilic properties. The calcination process converts the shells into a material that contaminants such as TSS, COD, and BOD. This utilization not only mitigates pollution but also creates opportunities for adsorbent products with economic value, especially in coastal areas where shell waste is abundant. However, this application must take into account ecological and health impacts, as overharvesting and non-environmentally friendly processing can damage the ecosystem. A sustainable approach with environmentally friendly regulations and technologies is essential to maximize the benefits of clam shells as adsorbents.  

The development of electric propulsion systems has become a major focus in efforts to provide energy-efficient and environmentally friendly air propulsion technology. One emerging innovation is the electric motor-based turbojet fan, which is expected to replace conventional fossil-fueled systems. As the need for energy efficiency increases, studies on electrical power consumption and airflow performance are crucial in supporting the development of new-generation propulsion systems. This study aims to evaluate the relationship between nozzle angle and the characteristics of electrical power consumption and airflow velocity in a double-spool turbojet fan. The method used is an experimental test with an ESP32-based control system. The duty cycle is set at 80% to maintain operational stability. Research data is obtained through measurements of electrical current, voltage, and airflow velocity. The nozzle angle variations tested include 13°, 19°, and 25°. The test results show a significant difference between nozzle angle variations on electrical power consumption and wind speed performance. The 13° nozzle angle produces the highest electrical power consumption, indicating a greater energy requirement to maintain airflow. Conversely, the optimal wind speed was found at an angle of 19°, indicating a balance between energy efficiency and aerodynamic performance. Meanwhile, an angle of 25° showed a decrease in performance in terms of both power and speed, making it less effective. In conclusion, the nozzle configuration has a direct influence on energy consumption and fluid dynamics in electric turbojet fan systems. This research provides an important contribution to the design of electric-based propulsion systems by emphasizing efficiency and performance aspects, while supporting the transition to environmentally friendly technologies.

This study aimed to evaluate the effect of compost fertilizer and potassium chloride (KCl) fertilizer, as well as their interaction, on the growth and yield of sweet corn (Zea mays saccharata Sturt). The experiment was conducted from May to August 2022 in Kuning Village, Bambel District, Southeast Aceh, using a factorial randomized block design with two factors: compost dosage (480 g/plot, 960 g/plot, 1,440 g/plot) and KCl dosage (20 g/plot, 40 g/plot, 60 g/plot), each replicated three times for a total of 27 plots. Observed parameters included plant height, stem diameter, leaf area, days to flowering, ear length, and ear weight per plot. Results indicated that compost and KCl fertilizers significantly affected plant height, leaf area, days to flowering, and ear length, but had no significant effect on stem diameter or ear weight per plot. The interaction between compost and KCl produced the highest plant height (165.89 cm) and ear length (21.69 cm) in treatment K3C1. The findings suggest that optimal fertilization using compost and KCl can enhance sweet corn productivity by improving vegetative growth and reproductive development. Nevertheless, the absence of significant effects on stem diameter and ear weight per plot indicates that nutrient balance, especially nitrogen (N) and phosphorus (P), remains crucial for maximizing yields. Therefore, integrating compost and KCl with complementary sources of macronutrients could promote more consistent outcomes. This research also highlights the role of organic matter in enriching soil fertility, maintaining soil structure, and supporting sustainable agriculture. The combination of organic and inorganic fertilizers demonstrates the potential for eco-friendly crop management practices that balance productivity with environmental responsibility. These results provide valuable insights for farmers, agronomists, and policymakers in developing efficient fertilization strategies for sweet corn cultivation within local conditions.

Propagation of rose plants through stem cuttings is a widely used method; however, its success is often influenced by the availability of adequate plant growth regulators and nutrients. The use of natural materials such as shallot extract as a source of plant growth regulators and cow manure as an organic fertilizer is expected to enhance the growth of cuttings in an environmentally friendly manner. This study aimed to determine the effect of soaking duration in shallot extract, the application of cow manure, and the interaction between both treatments on the growth of rose (Rosa hybrida L.) cuttings. The research was conducted in November 2025 in Sampe Cita Glugur Rimbun Village, Kutalimbaru District, Deli Serdang Regency, North Sumatra, at an altitude of approximately 500 meters above sea level. The study employed a factorial Randomized Block Design with two treatment factors and three replications, resulting in 48 experimental units. The first factor was the soaking duration in shallot extract (0, 4, 8, and 12 hours), while the second factor was the dosage of cow manure (0, 50, 100, and 150 g per polybag). Observed parameters included survival percentage, time of shoot emergence, number of shoots, shoot length, number of leaves, and leaf length. The results showed that all treatments, both individually and in interaction, had no significant effect on all growth parameters. Nevertheless, plant growth increased with plant age, with a relatively high and uniform survival rate of approximately ±90%. These findings indicate that, at the treatment levels applied, shallot extract and cow manure were not effective in significantly improving the growth of rose cuttings, suggesting that further research with different concentrations or treatment combinations is needed.
