Abstract

The purpose of this study was to determine the optimal extraction method of potassium from corn cobs in semibatch and batch. In this research, semibatch maceration is a leaching process used to obtain the time needed for the solvent to absorb alkali in corn cob ash. While the batch system maceration is a leaching process used to obtain the amount of time needed for the solvent to reach saturation point. Data collection techniques in this research are: sample preparation and drying of corn cobs, corn cobs pyrolysis, semibatch and batch maceration of corn cobs ash, and determination of alkali content by titration method. From the results, it can be concluded that corn cobss have the potential to be used as a source of alkali because the potassium (K) content in corn cob ash is 25.78%. The moisture content and yield of corn cob ash were 77.5% and 17%, respectively. The saturated solvent time for semibatch maceration was 3.5 days, while for batch maceration it was 12 days. Where at consecutive ratios of 1 gram/25 mL; 2 grams/25 mL; 3 grams/25 mL; and 4 grams/25 mL each had concentration values that still increased from 0.112 N to 0.9672 N; 0.223 N to 3.2364 N; 0.3348 N to 2.0646 N; and 0.558N to 3.6828 N. The highest alkali yield was obtained at a corn cob ash/solvent ratio of 1 gram/25 mL, which was 20.15%.

Abstract

The Peatland Care Independent Village (DMPG) program in North Sumatra, implemented in 2024, was designed to enhance environmental quality, protect, and sustainably manage peatland ecosystems. The program involved structured community engagement through various stages, including the recruitment of community facilitators, technical training, the establishment of peatland ecosystem task forces, the development of community activity plans (RKM), and the implementation and presentation of these plans. It was carried out in 12 villages across four districts in North Sumatra. Activities focused on local economic development, such as crop and livestock farming, handicraft production, and capacity building for the community. The stages of the DMPG program are implemented simultaneously and continuously, involving all levels of society and monitored by the university and a delegation from the Ministry of Environment and Forestry. At the end of the program, an evaluation was conducted to measure the impact on the quality of the peatland environment and the economic improvement of the communities in the 12 target villages. The results showed significant improvements in the environmental quality of peatland areas and local economic growth. A survey conducted across 12 villages revealed that 10 villages considered the program highly beneficial in improving the environmental quality of peatland areas, while 2 villages found it beneficial. Regarding economic benefits, 8 villages reported significant improvements in local economies, and 4 villages reported moderate benefits. The program successfully raised community awareness of the importance of peatland conservation and fostered an effective collaborative model involving universities, government agencies, and local communities. These findings underscore the importance of an integrated approach to restoring the ecological functions of peatlands and improving the welfare of surrounding communities.Program Desa Mandiri Peduli Gambut (DMPG) di Sumatera Utara tahun 2024 dirancang untuk meningkatkan kualitas lingkungan, melindungi, dan mengelola ekosistem gambut secara berkelanjutan.

Abstract

Abstract: Sansevieria Trivasciata (snake tongue) is a traditional medicinal plant known to contain various bioactive compounds. This study aims to identify secondary metabolite content and characterize Sansevieria leaf crude extract. Plant samples were obtained from Aekbolon village, North Sumatra, and have undergone a taxonomic identification process. The crude extract was prepared by drying and grinding the leaves. The characterization results showed a water content of 8.5% and a water-soluble extract content of 23.85%, which is in accordance with the quality standards of crude extracts according to the Indonesian Herbal Pharmacopoeia. Extraction was carried out using a maceration method using 96% ethanol for three consecutive days. The resulting thick extract was then tested qualitatively to detect secondary metabolites. The screening results showed the presence of allkaloids, flavonoids, saponins, and steroids, while tannins were not detected. These findings indicate that Sansevieria has potential as a source of natural active ingredients for the development of herbal medicines.

Abstract

This study aims to determine the effect of the Problem Based Learning (PBL) model on student learning outcomes and science process skills in thermochemistry material. This study employed a quasi-experimental design with a pretest-posttest control group design. The research population was grade XI students of SMA Negeri 1 Silaen. Sampling was conducted using a random sampling technique, resulting in class XI-2 with 35 students as the experimental class implementing the Problem Based Learning model, and class XI-3 with 35 students as the control class using conventional learning. The results showed that the mean score of learning outcomes in the experimental class was 82.86 and the control class was 76.57. The hypothesis test showed >  (3.859 > 1.667), indicating a significant effect of the problem based learning model on student learning outcomes in thermochemistry material. The average science process skills of the experimental class reached 82.46% categorized as very good, higher than the control class at 78.06% categorized as good. Correlation analysis using the product moment correlation obtained  of 0.717, indicating a strong correlation between science process skills and learning outcomes, with a coefficient of determination of 51.44%. Thus, the problem based learning model is proven to effectively improve student learning outcomes and science process skills significantly in thermochemistry material.
