Abstract

The development of renewable energy sources is important due to the increasing demand for electricity. Microbial Fuel Cell (MFC) is a technology that utilizes microorganisms to convert organic substrates into electrical energy. This study aims to determine the potential of Aneurinibacillus thermoaerophilus strain N25 in producing bioelectricity at different starter concentrations. The research was conducted using an experimental method with variations of starter concentrations in an MFC system. Bioelectricity production was measured using a digital multimeter in millivolts (mV). The results are expected to provide information about the optimal starter concentration for bioelectricity production by thermophilic bacteria.

Abstract

Tomato plants (Solanum lycopersicum L.) are horticultural commodities that have high nutritional value and economic value and are widely needed by the community. The increase in demand for tomatoes needs to be balanced with efforts to increase production through proper cultivation techniques, one of which is through fertilization. The continuous use of inorganic fertilizers can reduce soil fertility and negatively impact the environment, so a more environmentally friendly fertilization alternative, such as the use of liquid organic fertilizer (POC), is needed. FloraOne® liquid organic fertilizer contains nutrients and microorganisms that have the potential to support plant growth. This study aims to determine the effect of applying FloraOne® liquid organic fertilizer on the growth of tomato plants. The research was carried out using an experimental method with a Complete Random Design (RAL) consisting of seven FloraOne® concentration treatments, namely P0 (control), P1 (0.1%), P2 (0.2%), P3 (0.3%), P4 (0.4%), P5 (0.5%), and P6 (0.6%) with four replicates. The observed parameters included plant height, stem diameter, wet weight, dry weight, and flowering age. The data was analyzed using the Analysis of Variance (ANOVA) test at a significance level of 5%. The results showed that the application of FloraOne® liquid organic fertilizer did not have a significant effect on the height, diameter, wet and dry weight of tomato plants (p>0.05) while P3 and P6 showed the appearance of flowers in the 8th week. However, descriptively, the 0.3% concentration treatment showed a better growth tendency than the other treatments.

Abstract

This research explores the potential of chicken eggshell waste as an alternative biofertilizer to reduce dependence on synthetic chemical fertilizers, which often trigger land degradation. The main focus of this study was to analyze the extent to which eggshell powder application affects the vegetative phase of peanut (Arachis hypogaea L.) plants, while also determining the most responsive application dose. The experiment was conducted with a four-stage treatment design: P0 (control), P1 (133.3 g/polybag), P2 (200 g/polybag), and P3 (266.6 g/polybag). Parameters observed included plant height dynamics and leaf productivity. The results showed that the integration of eggshell biofertilizer significantly stimulated plant growth compared to the control. The P3 dose (266.6 g/polybag) was identified as the most effective treatment, with an average plant height of 26 cm and 32 leaves at the end of the observation period. Interestingly, at the intermediate dose (P2), there was evidence of inhibition of stem elongation despite the high leaf count. This phenomenon is thought to be related to nutritional imbalances caused by excess calcium (Ca), which inhibits the absorption of other essential micronutrients. Overall, this study confirms that the use of eggshell waste not only serves as a natural source of calcium carbonate (CaCO₃) for soil pH stabilization but is also effective in sustainably improving the agronomic performance of peanuts.
