Effect of Sensor and Based NPK on the Growth of Pakcoy (Brassica rapa L.) Cultivation Hydroponic
Get PDFIn hydroponic cultivation, the effectiveness of nutrient distribution is crucial in ensuring optimal plant growth. This research aims to compare the efficiency of nutrient solution delivery using an Internet of Things (IoT)-based NPK sensor with the conventional manual method on the growth of pakcoy (Brassica rapa L.). The study was conducted using a Completely Randomized Design (CRD) with two treatment groups: one utilizing IoT-based NPK sensors and the other without sensors. Each treatment was repeated twice, with nine plant samples per repetition. The observed growth parameters included plant height, number of leaves, leaf area, fresh weight, and dry weight at six weeks after planting. The findings revealed that the implementation of IoT-based NPK sensors significantly enhanced the growth of pakcoy plants compared to the manual method. This was evidenced by a notable increase in plant height, leaf area, and fresh weight (p < 0.05). In conclusion, the application of IoT technology improves the efficiency and effectiveness of nutrient distribution in hydroponic systems, positively impacting plant growth. The scientific significance of this research suggests that integrating IoT-based technology into hydroponic farming can serve as an innovative approach to enhancing plant productivity in a precise and sustainable manner

This study aims to determine the analgesic effect of leunca leaf ethanol extract and determine the dose of leunca leaf ethanol extract that has the highest analgesic activity with the Randall Selitto method. Randall Selitto method has been widely used for the development of non-steroidal anti-inflammatory drugs. Leunca leaf powder was extracted using maceration method with 96% ethanol solvent. A total of 25 wistar male white rats were divided into 5 groups, namely positive control mefenamic acid 9 mg / 200 g BW, negative control CMC Na 1%, ethanol extract of leunca leaves doses of 5 mg / 200 g BW, 10 mg / 200 g BW and 20 mg / 200 g BW. The data obtained were analyzed by ANOVA test, then LSD test was used to determine the differences between groups. The results showed that the extract doses of 5 mg / 200 g BW, 10 mg / 200 g BW, 20 mg / 200 g BW and positive control were significantly different from the negative control group. The extract dose of 20 mg / 200 g BB is comparable to the positive control, indicating that the extract dose of 20 mg / 200 g BB has the highest analgesic activity. Steroid and flavonoid compounds contained in leunca leaves are thought to have an effect as analgesics
Life-Long Learning Profile of Junior High School Students in Science Learning
Get PDFImplementing life-long learning is vital to help students face rapid global development. Life-long learning is a principle in organizing education and a primary need for everyone to adapt to changing times. This study aims to analyze the application level of lifelong learning among SMP Negeri 1 Pucakwangi students, especially class VII students. This study used a descriptive qualitative approach with a sample of 28 students. Data were collected through a questionnaire containing five life-long learning indicators: complex thinking, information processing, effective communication, collaboration/cooperation, and habits of mind. The results showed that overall, the level of life-long learning application of students at SMP Negeri 1 Pucakwangi was still in the poor category, with an average score of 2.8 out of a 4.0 scale. Students obtained a high score (3.0) in the complex thinking indicator. In contrast, in other indicators, such as information processing (2.7), effective communication (2.6), collaboration/cooperation (2.8), and habits of mind (3.1), the scores obtained were still relatively low. The three indicators that obtained low scores, namely information processing, effective communication, and collaboration/cooperation, indicate that students still need further development in these skills. Based on the study results, it can be concluded that although some indicators show good results, there are also indicators that need to be improved to optimize the implementation of lifelong learning. Therefore, there is a need for further efforts in improving students' skills, especially in terms of information processing, effective communication, and collaboration, so that they can be better prepared to face the growing global challenges

The chemistry teaching modules made by teachers have begun to apply the principle of Understanding by Design (UbD). However, the chemistry teaching modules must be completed, especially in the assessment section
Improving the Quality of Gembili Pickle (Dioscorea esculenta) Through Fermentation with Starter Culture Lactobacillus plantarum B1765
Get PDFGembili is a type of tuber that grows widely in Indonesia and has the potential to be developed into functional food, but its utilization has not been optimal. One of the efforts that can be made is the development of gembili as pickle, a synbiotic fermented product of gembili by a starter culture of Lactobacillus plantarum B1765, which has been known as a probiotic. This study examines the effect of fermentation duration on the growth of total lactic acid bacteria (LAB), pH value, Total Titratable Acidity (TTA), and organoleptic quality aspects. The gembili tubers were cut into sticks and fermented for 0, 2, 4, and 6 days, using Lactobacillus plantarum B1765 starter culture at 37℃. Total LAB was calculated by total plate count (TPC), pH by pH meter, TTA by acid-base titration, and organoleptic test using untrained panellists to assess the preference level using a hedonic scale. The results showed that total LAB increased from the beginning of fermentation (2.37 x 107 CFU/mL) to 1.15 x 108 CFU/mL fermentation 4 days but decreased to 1.01 x 105 CFU/mL at the end of fermentation (6 days). The pH decreased from 6.43 ± 0.02 to 3.07 ± 0.002, and TTA increased from 0.31 ± 0.010% to 0.53 ± 0.008% at the end of fermentation (6 days). Organoleptic test results showed that fermentation time affected the preference level for color, taste, aroma, and texture. The highest preference level of the four aspects was the product with a fermentation time of 4 days with a preference level in the very like category. The results of this study indicate that the optimal time of gembili pickle fermentation is 4 days based on the total amount of LAB (> 106 CFU/mL), TTA (> 0.20%), pH (3.4-4.3) has met SNI criteria and also shows the highest preference level in color, taste, aroma, and texture. Gembili pickles can be recommended to be developed as a safe synbiotic product
