Abstract

The high productivity of corn in Kendal Regency produces a large amount of waste that has not been optimally utilized. Therefore, appropriate technology needs to be applied to convert corn cobs into a growing medium for oyster mushrooms. Oyster mushrooms were chosen because they are among the most popular edible mushrooms in society and have relatively stable market prices, making them suitable for cultivation. The purpose of this program is to improve the knowledge and skills of the Sekandang Farmers Group in producing oyster mushroom growing media using corn cob waste. The method used in this community service activity involves both theoretical and practical training, including corn cob grinding, mixing with rice bran and lime, sterilization using a steamer machine, seeding, as well as basic financial management and marketing strategies (both online and offline). The results of the program, based on interviews and pre-test and post-test evaluations, show a significant increase in participants’ scores, indicating improved knowledge and skills among the farmers. In addition, participants demonstrated high enthusiasm and active participation during the practical sessions. In conclusion, this training successfully enhanced the farmers’ ability to utilize corn cob waste as an effective growing medium for oyster mushrooms, thereby supporting the improvement of their economic welfare.

Abstract

Biomass as an energy source is very compatible with Indonesia's natural resources. Pineapple peel waste contains a lot of cellulose, which can be used as a renewable energy source. However, the presence of lignin in pineapple skin stops the hydrolysis process. So, this research looks at how the MAE (microwave assisted extraction) delignification method optimizes pineapple peel waste cellulose. The results of research by changing the operating temperature to 70oC, 80oC, and 90oC show that lignin solubility increases with operating temperature. To compare, the control sample had lignin and cellulose solubility of 2.68% and 17.39% of the sample weight, while the sample delignified with MAE had a solubility of 9.04% and 29.42% of the sample weight at an operating temperature of 90oC, for two twenty minutes, and with a ratio of 1:20 (w/v). After delignification, analysis continues using FTIR to compare the organic components in the sample. In the graph of microwave pretreatment spectra results, wide absorption is found at 3320 and 3333 cm-1; The spectra results without pretreatment show free O-H vibrations from a group of hydroxyls in the cellulose molecule. The peaks that have changed can be seen in the graph of the microwave pretreatment spectrum results, which shows wave values ​​of 1625 and 1630 cm-1, and shows the vibration of the aromatic chains in lignin. The cellulose peaks are 1032 and 1034 cm-1. These peaks are glucose ring stretching, changes in the C-H form in hemicellulose and cellulose.

Abstract

Zero net emission has become a global issue that is being discussed intensively along with the development of technology to the point of giving birth to various policies that have been issued by many countries in the world. One way to realize this is by diversifying green energy. Bio energy is the right solution to achieve this global goal, namely the utilization of pineapple skin waste as raw material for biogas production. so it is very appropriate to conduct research to examine the effect of adding pineapple skin waste to increase biogas production with microwave treatment and process optimization. The optimum condition of the temperature variable obtained the best results at a temperature of 900C with a cellulose solubility of 29.42%, while the lignin solubility obtained was 9.05% which can be concluded that MAE pretreatment can increase the solubility of the cellulose and lignin composition. Furthermore, the optimum condition for biogas production was produced in pineapple skin samples with MAE treatment with a ratio of 1:2 (w/v) of 917mL. From the research that has been carried out, it shows that along with the increase in total solids entered into the biodigester, the amount of biogas production produced will increase.

Abstract

Heavy metal pollution such as chromium (Cr) in industrial wastewater is a serious environmental problem because of its impact on human health and aquatic ecosystems. One effective method to reduce Cr levels in waste is adsorption using activated carbon based on natural materials. This study aims to examine the effectiveness of activated carbon obtained from pyrolysis wood twig waste in absorbing Cr ions. Activated carbon was activated using sulfuric acid (H₂SO₄) with concentration variations of 1, 3, and 5 M to increase adsorption capacity. Adsorption tests were carried out with contact time variations of 60, 90, and 120 minutes, and analyzed using Atomic Absorption Spectroscopy (AAS). The results showed that activated carbon with H₂SO₄ activation increased adsorption capacity against Cr ions. The higher the concentration of H₂SO₄, the lower the water content and ash content in activated carbon, which indicates an increase in surface area and porosity. The effect of initial Cr concentration on adsorption effectiveness was also observed. At an initial concentration of Cr of 10 ppm, activated carbon was able to absorb up to 58.73% of the total metal ions present. However, when the initial concentration was increased to 25 ppm, the adsorption effectiveness decreased to 41.28%. At a higher concentration, namely 50 ppm, activated carbon was only able to absorb 34.78% of Cr ions. These results indicate that activated carbon from pyrolysis wood twig waste can be an economical and environmentally friendly alternative for the treatment of waste containing heavy metals.
