Abstract

Corn (Zea mays) is a widely cultivated crop in Gorontalo and has high economic value as well as an important role in food security. Fertilization is one of the key factors that influence the productivity of corn plants. This research aims to determine the combination of NPK fertilizer doses granulated with Biochar-Chitosan in enhancing the growth and productivity of corn plants, as well as its impact on the quality of total N soil content. The study was conducted by planting corn, applying fertilizer, and observing its growth through measurements of plant height, leaf length, stem diameter, cob weight with husk, and cob weight without husk. The observational data were then analyzed descriptively, summarizing or classifying the data set to provide an overview of the data. Additionally, the analysis of soil N-total content was conducted before and after the application of fertilizers. The research results show that the combination of NPK-Biochar fertilizer doses has a significant impact on the growth and productivity of corn plants. The 7.5-gram NPK-Biochar fertilizer dose yielded the best results in increasing plant height, number of leaves, stem diameter, and cob weight with and without husks compared to other doses. Soil chemical property analysis also indicates that the application of NPK-Biochar fertilizer has a positive impact on the quality of the soil's total nitrogen content.

Abstract

Tabongo Timur Village, located in the Tabongo Subdistrict, Gorontalo Regency, has significant potential for developing Sacha Inchi as a leading commodity to support food security and enhance the local economy. This empowerment program aims to increase the productivity and quality of Sacha Inchi plants through social, technical, and technological interventions. The program employs the Participatory Rural Appraisal (PRA) approach to actively engage the community in the planning and implementation processes. The methods used include cultivation socialization, technical guidance, product innovation training, and technology implementation for post-harvest processing. The results of the program showed a significant increase in plant productivity and the quality of Sacha Inchi products, achieved through the application of semi-organic cultivation techniques, the use of modern tools, and education related to product innovation. The training provided also improved partners' skills in processing Sacha Inchi into high-value products, such as oil, milk, jam, and snack bars. The discussion shows that this program successfully shifted farmers' mindsets towards better utilization of local potential and strengthened community involvement in productive agricultural activities. Collaboration between the village government, university, and farmer groups was key to the program's success, making Tabongo Timur Village a competitive Sacha Inchi processing center. This program can serve as a model for other villages in empowering local resources to support food security and improve community welfare.

Abstract

This research aims to formulate and examine the physicochemical characteristics and antioxidant activity of sacha inchi (Plukenetia volubilis L.) as a plant-based milk. Moreover, this research also aims to conduct organoleptic tests on the products. The sacha inchi milk is formulated with five ratios: SI1 (sacha inchi 1:10 parts water), SI2 (sacha inchi 2:10 parts water), SI3 (sacha inchi 3:10 parts water), SI4 (sacha inchi 4:10 parts water), and SI5 (sacha inchi 5:10 parts water). Organoleptic tests are carried out by assessing the aspects of taste, color and aroma of the product with a score range of 1 (least preferred) - 5 (most preferred). The results of the organoleptic test showed that the most preferred sacha inchi peanut milk formulation was SI5 with a preference level reaching a score of 4.48. The SI5 formulation is more dominantly preferred because it is richer in taste, color and aroma. Then continued with physicochemical testing which includes water content, ash content, fat content, protein content, carbohydrate content, calcium content, pH, and viscosity and IC50 antioxidant activity test using UV-Vis Spectrophotometer instrument. The results of physicochemical tests and IC50 antioxidant activity conducted in this study were respectively: water content (74.10%), ash content (0.65%), fat content (19.15%), protein content (4.29%), carbohydrate content (1.82%), calcium content (0.043%), pH (6.01), viscosity (209 mPa∙S), and IC50 antioxidant activity (429.10 ppm).

Abstract

Corn is the main commodity product and the flagship of Gorontalo Province, ranked in the top 10 in Indonesia. In Daenaa Village, West Limboto Subdistrict, corn has not been maximally processed to increase creative economic growth due to limited knowledge and processing techniques, even though Daenaa Village is a corn production center in Gorontalo Regency. This community service activity aims to improve the skills and income of the residents of Daenaa Village, West Limboto District, through training in making processed corn products such as tortilla chips and corn milk. The training on making tortilla chips involves the process of boiling corn with lime water, mixing spices, adding corn flour, to shaping and drying to produce a durable ready-to-fry product. Meanwhile, the process of making corn milk includes boiling young corn, grinding, filtering, and adding sugar, flavor, and CMC to create a nutritious drink with a soft texture. The final product is hygienically packaged and labeled to increase its selling value. The results of the activity showed an increase in participants' knowledge and skills in processing corn into value-added products that have the potential to become micro-enterprises. Hopefully, this program can be the first step for the people of Daenaa Village to utilize local potential as a new source of sustainable income.

Abstract

This research focuses on Natural Science learning, especially colloid material, where teaching is still dominated by the lecture method. Learning models that encourage students to make direct observations through experiments are rarely applied. This causes students to be less trained in solving problems, so their critical thinking skills are not optimally developed. This study aims to determine the effect of STEM (Science, Technology, Engineering, and Mathematics) learning model on students' critical thinking skills on colloid material at SMA Negeri 1 Telaga. The research design used was pre-experiment with one group pre-test post-test design. The research sample consisted of 29 students selected by census/total sampling. Data collection was done through critical thinking skills test. The results showed that the average percentage of students' critical thinking skills in the pre-test was 46.11%, which was in the medium category, and in the post-test it increased to 83%, which was in the very high category. This shows that the STEM learning model can improve students' understanding and critical thinking skills. The statistical test shows a significance value of 0.000 < 0.05, which means H1 is accepted and H0 is rejected. Thus, it can be concluded that the STEM learning model has a positive influence on students' critical thinking skills.
