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

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.

Abstract

Many rimbang harvests, which are local vegetables from Central Kalimantan, are damaged and then thrown away because they are not marketable. This is clearly due to the relatively short shelf life of rimbang fruit. Farmers who depend on the harvest as their main source of income will certainly be disadvantaged by this. In addition, rotten rimbang vegetables will have a negative impact on the environment because they produce methane gas, one of the gases that causes global warming. So this community service program innovates rimbang, where rimbang is made into a syrup drink. Rimbang syrup can be a new innovation to create new products that are competitive, have high selling value, and are durable. The implementation of the community service program took place in the Habaring Hurung Village farmer group, Bukit Batu District, Palangka Raya City, Central Kalimantan Province. This activity program was carried out through 4 stages of activities, including location surveys, collection of raw materials, training in making eggplant dodol, and success indicators. The success indicators were carried out using the pre-test and post-test methods filled out by the activity participants in the form of a questionnaire. Based on the results of the activity, it can be concluded that this activity is able to increase insight and ability on how to make syrup with rimbang as the basic ingredient, even the residents can implement and apply this food innovation independently.

Abstract

The Kahayan River in Central Kalimantan is one of the waterways utilized for traditional gold mining that employs amalgamation techniques. The application of this method poses a significant risk of environmental pollution and degradation. This study was conducted to evaluate the capacity of bacteria to act as bioremediation agents for mercury (Hg) at different concentrations. The methodology involved inoculating sediment samples into Zobell 2216E medium, isolating and purifying bacterial colonies on Nutrient Agar (NA), followed by bacterial identification and assessment of mercury degradation using an Atomic Absorption Spectrophotometer (AAS). The findings revealed that isolate 34 was able to remove 132.73 ppm of Hg from an initial concentration of 250 ppm (equivalent to a 53.09% reduction), whereas isolate 108 removed 139.68 ppm, corresponding to a 55.87% reduction.

Abstract

The objective of this research is to assess the adsorption capacity of activated carbon derived from meranti wood (Shore spp) for mercury (Hg) removal from liquid waste. To establish the relationship between concentration and absorbance, the method employed involves calibrating mercury concentration using calibration curves. Additionally, the effects of pH and exposure time on adsorption capacity were examined. The results indicate that activated carbon from meranti wood can significantly adsorb mercury, achieving an efficiency level of 97.610% at pH 3, with adsorption stability reached within 80 minutes at an adsorption rate of 94.30%. The conclusions drawn from this study suggest that activated carbon from meranti wood is a sustainable and effective solution for addressing mercury contamination in wastewater. It also highlights the importance of regulating pH and exposure time. This research contributes significantly to the development of environmentally friendly methods for water purification.
