Abstract

Zircon sand mining is a major industry in Indonesia due to the country's vast zircon reserves. However, this industry also generates hazardous waste that can pollute the environment. This study aims to investigate the potential of magnetite (Fe₃O₄) synthesized from magnetic waste generated during zircon sand mining as an adsorbent for methylene blue dye removal. Magnetite was successfully synthesized via the co-precipitation method and characterized using XRD and FTIR. The synthesized magnetite demonstrated the ability to adsorb methylene blue from aqueous solutions with an adsorption efficiency of 68.52% after 80 minutes of contact time. The adsorption kinetics followed the pseudo second order model, evidenced by R² value of 0.9918, and the adsorption isotherm fitted the Langmuir model, indicating adsorption energy of 24.51 kJ/mol and adsorption capacity of 69.678 mg/g. These findings demonstrate the effectiveness of natural magnetite (Fe₃O₄) derived from zircon sand waste as an adsorbent for methylene blue dye removal. This research not only addresses the environmental issue caused by zircon sand mining waste but also develops a cost-effective and sustainable solution for methylene blue dye removal from wastewater.

Abstract

Hanjuang Merah (Cordyline fruticosa) is one of the plants used by the Dayak people as traditional medicine. Red hanjuang is an ornamental plant that is very abundant in Indonesia, but there is still not much research that proves the efficacy of red hanjuang. The aim of this research was to determine the phytochemical screening and antibacterial activity of leaf extract of hanjuang merah (Cordyline fruticose) against the bacteria Staphylococcus epidermidis. The method used in sample extraction was maceration, while in the antibacterial test used the paper strip diffusion method with concentrations of 25%, 50%, 75% and 100%. The yield of ethanol extract of hanjuang merah leaf was 11.35%. There was an increase in the diameter of the inhibition zone with the addition of the concentration of ethanol extract of hanjuang merah leaf. The addition of ethanol extract of hanjuang merah leaf at a concentration of 75% sensitive inhibited the growth of Staphylococcus epidermidis bacteria. Secondary metabolites such as tannins, alkaloids, saponins, flavonoids and quinones found in ethanol extract of hanjuang merah leaves are considered responsible for inhibiting the growth of Staphylococcus epidermidis bacteria.

Abstract

Purpose: Stunting is a condition in which a child's physical growth and development are hampered due to malnutrition during the growth period. This condition occurs in children under 5 years of age. This age period is critical for the formation and development of body organs in children. Therefore, an innovative and holistic approach is needed to prevent stunting. One potential that can be exploited is the fruit of the karamunting plant (Rhodomyrtus tomentosa), which has traditionally been used as an herbal medicine. Candy containing healthy and delicious caramunting fruits can be an interesting way to increase nutritional intake, especially for children who have barriers to consuming nutritious food. Methodology: Implementation of community service through an educational workshop on the importance of knowledge about stunting prevention in children through local food innovation with Karamunting fruit candy (Rhodomyrtus tomentosa) was carried out on Saturday, October 7, 2023, between: 08.00-11.00 WIB, with the activity location at Habaring Hurung Village Hall. The partners for this community service activity are the heads and staff of Habaring Hurung Village, Bukit Batu District, Palangka Raya City, and Central Kalimantan. The targets of this service activity are mothers and children in Posyandu. Service procedures are the coordination, observation, activity implementation, and evaluation stages. Results: The participants understood the dangers and prevention of stunting in their children. The participants understood how to make karamunting fruit candy a local food that can be used and developed. Limitations: Karamunting fruit candy as a food innovation to prevent stunting produced by this community service program has no known expiration date or shelf life and there is no standard composition or dosage for candy to prevent stunting. Contribution: This community service activity can have a positive impact on the people of Hurung Village. This activity is able to increase insight and the ability to prevent the spread of stunting through innovation in making candy from karamunting fruit, even if residents can implement it independently.

Abstract

Kelakai (Stenochlaena palustris) is a type of medicinal fern used by the Dayak ethnic community in traditional medicine. The diverse bioactivity of kelakai is closely related to its high antioxidant content. The phytochemical compounds found in kelakai, such as phenols, flavonoids, anthocyanins, hydroxycinnamic acid, proanthocyanidins, tannins, alkaloids, saponins, carotenoids, and terpenoids, are believed to be produced by the endophytic microbes present in kelakai. Endophytic bacteria can be isolated from the plant, such as leaves, stems, bark, and roots. This research aims to isolate and identify endophytic bacteria from S. palustris. The method used is direct planting. The samples used are the leaves and stems of S. palustris. The results of the research conducted revealed six isolates of endophytic bacteria found in the leaves and stems, namely D1, D2, B1, B2, B3, and B4, which exhibit different colony morphology on the surface and color, while having similar shapes and edges. The results of the Gram staining test on the endophytic bacteria showed negative results and they are rod-shaped. In this study, endophytic bacteria S. palustris were successfully obtained from leaves and stems, which can be further analyzed for their activity.

Abstract

One of the solutions developed for utilizing organic materials in agriculture is the use of biological fertilizer. This research is different from previous fertilizer research, where the biofertilizer in this study came from empty palm oil bunches, animal waste by using maggots (BSF larvae, Hermetia illucens) and local microorganisms to degrade them. The aim of this research is to obtain the composition of organic biofertilizer from three wastes that have been processed using maggots and local microorganisms. This research method uses RAL with 12 treatments with 3 repetitions. The results of a study of organic biofertilizer from BSF larvae and a consortium of local microorganisms on white mustard plants (Brasica chinensis) showed that treatment with a combination of animal waste, microbes and BSF larvae showed good results on the growth of white mustard plants. This is proven by the results of measuring soil pH, the highest height of chicory plants and the highest number of leaves compared to other organic biological fertilizer treatments, which were produced at the end of the measurement on day 30, the pH in the treatment with that combination is 4, plant height is 33 cm, and the number of leaves is 20.

Abstract

This study focuses on the utilization of ironwood as an activated carbon adsorbent to remove heavy metal mercury (Hg). The background of the problem includes mercury pollution from various industrial sources and its harmful impacts on the environment and human health. The purpose of this study was to develop an effective method for adsorbing mercury using natural ironwood materials. The research method involves the synthesis of activated carbon through pyrolysis and chemical activation processes, followed by a series of adsorption tests on mercury with variations in pH conditions, contact time, and acid concentration. The research data showed that the optimum adsorption capacity was achieved at a mercury concentration of around 500 ppm, with high adsorption efficiency at pH 1 and a contact time of 80 minutes. The results also showed that the adsorption kinetics followed a second-order model with a rate of 0.017119 g/mg.min. In conclusion, the mercury adsorption process using activated carbon from ironwood followed the Langmuir isotherm model, with an adsorption capacity of 63.036 mg/g, indicating that the adsorbent had been successfully synthesized and had an effective ability to remove mercury.
