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

An analysis of the silica nanosol-hexadecyltrimethoxysilane hybrid has been carried out through optimizing the concentration of silica nanosol and determining the type of fabric regarding hydrophobicity. This research began with the synthesis of silica nanosol via the sol-gel method, where TEOS as a precursor was dissolved in a mixture of ethanol-distilled water with a base catalyst with a contact time of 2 hours. The concentration of silica nanosol was varied by 0.025, 0.05, and 0.075 mol. The dip-coating method was used to coat the fabric with nanosol, with a tensile rate of 3 cm per second. Then the fabric was re-coated with silica nanosol in HDTMS solution (4% wt/wt ethanol) and dried in a 120°C oven for 10 minutes. This research tested calico, cotton and mori fabrics. A Canon DSLR camera with a Thamron 100mm lens was used to measure the contact angle of the fabric surface. ImageJ software processes images to obtain contact angle values on the fabric surface. The fabric was then characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM) and the silica nanosol was characterized using a Transmission Electron Microscope (TEM). The optimum concentration of silica-hdtms nanosol was obtained at a concentration of 0.075 mol with surface contact angles of cotton, mori and calico fabrics of 134, 132 and 135°. The flow speed of water with a slope of 100 on cotton, mori, and calico fabric produces flow speeds of 3.3, 6, and 5 m/s.

Abstract

Abstrak Indonesia merupakan negara produsen dan eksportir kelapa sawit terbesar di dunia, yang menghasilkan limbah biomassa yang melimpah. Produksi minyak sawit tahun 2018 di Indonesia sebesar 34,94 juta ton dengan hasil samping berupa tandan kosong (23%), mesokarp serat (12%), dan cangkang sawit (5%). Cangkang inti sawit merupakan biomassa potensial yang dapat meningkatkan kualitas sebagai bahan bakar padat melalui proses termokimia. Pemanfaatan limbah hasil industri kelapa sawit menjadi bahan bakar dengan modifikasi termokimia dapat menjadi salah satu solusi untuk membuat nilai tambah dari limbah tersebut. Torefaksi adalah salah satunya proses termokimia yang saat ini digunakan untuk meningkatkan kualitas biomassa. Metode yang biasa digunakan untuk proses torefaksi di laboratorium adalah metode batch. Namun, metode ini memiliki kelemahan ketika kapasitas ditingkatkan membuat penurunan kualitas bahan bakar yang dihasilkan. Dalam penelitian ini, kualitas cangkang sawit torefaksi dari batch luas permukaan internal dibandingkan dengan torrefaksi batch yang di modifikasi. Torefaksi proses dilakukan pada suhu 275° C, dengan waktu 30 menit. Hasilnya menunjukkan bahwa torefaksi dari metode batch yang dimodifikasi memiliki nilai kalor yang lebih baik, dan dekat dengan bahan bakar. Abstract Indonesia is the largest producer and exporter of palm oil in the world, which produces abundant biomass waste. Palm oil production in 2018 in Indonesia was 34.94 million tons with by-products in the form of empty fruit bunches (23%), fiber mesocarp (12%), and palm shells (5%). Palm kernel shell is a potential biomass that can improve its quality as a solid fuel through a thermochemical process. Utilization of waste from the palm oil industry into fuel with thermochemical modifications can be one solution to create added value from the waste. Torrefaction is one of the thermochemical processes currently used to improve the quality of biomass. The method commonly used for the torrefaction process in the laboratory is the batch method. However, this method has a disadvantage when the capacity is increased, resulting in a decrease in the quality of the resulting fuel. In this study, the quality of the torrefaction palm shells of the internal surface area batch was compared with the torrefaction of the modified batch. Torrefaction process was carried out at a temperature of 275°C, with a time of 30 minutes. The results show that the torrefaction of the modified batch method has a better calorific value, and is close to that of the fuel

Abstract

The Green Initiative conducted in Tumbang Habaon Village, Tewah District, Gunung Mas Regency, Central Kalimantan, aimed to improve environmental awareness and strengthen community capacity in the cultivation and sustainable management of potential plant species. Using a Participatory Action Research (PAR) approach, the program involved socialization activities, technical training, and the collaborative planting of 2,000 trees, including guava, petai, and jengkol. Community members received guidance on proper planting techniques, land preparation, and plant maintenance. The activity successfully increased community understanding of environmental conservation from 40% to 80%. The planted trees showed an 85% survival rate within the first six months, supported by routine mentoring. The program also generated early economic benefits for 50 households through the introduction of productive tree species and contributed to reducing flood risks and improving local biodiversity. Challenges faced during implementation—such as limited availability of quality seedlings and initial community reluctance—were addressed through cooperation with local government stakeholders. Overall, the Green Initiative serves as a practical community service model that promotes environmental sustainability, community participation, and local empowerment, with potential for replication in other rural villages facing similar environmental issues.

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.
