Abstract

Pomegranate (Punica granatum L.) is a fruit plant that is easy to grow in almost all climates. The utilization of this plant as a traditional medicine is very varied and all parts of the pomegranate plant (Punica granatum L.) can be used as medicine, one of which is pomegranate leaves. This study aims to determine the content contained in pomegranate leaves. Pomegranate leaves were extracted by maceration with 96% ethanol solvent. The extraction results then go through a color reaction compound test process. Testing of color reaction compounds includes saponins, steroids/terpenoids, flavonoids, alkaloids, and tannins. This study aims to analyze the content of chemical compounds contained in pomegranate leaves extracted using 96% ethanol. This research method includes maceration extraction and chemical compound screening tests using chemical reagents. The results showed that pomegranate leaves extracted using 96% ethanol solvent and phytochemical screening showed positive results on alkaloid compounds, steroids/terpenoids, flavanoids, tannins but on saponin metabolites showed negative results.

Abstract

Phytochemistry is a method used to determine the compounds found in plant essence. Phytochemical identification is carried out using chemical substances used in a reaction to determine the collection of secondary metabolite compounds. Indonesia is a country that has various types of medicinal plants, one of which is the leaves of Katang-katang (Ipomoea pes-caprae). Katang-katang is a tropical vine that is easy to find and belongs to the Convolvulaceae family. The utilization of this medicinal plant is one of the alternatives in an effort to treat a disease.  Along the road in the sandy beach area, many of these plants are found growing creeping on the edge of the shoreline, this plant has a trumpet-like flower and is known as Katang-katang (Ipomoea pes-caprae). (Ipomoea pescaprae L.). Empirically, people often use katang-katang plants to treat infections in wounds, relieve pain, and as antioxidants. The active compounds of katang-katang as antibacterial are terpenoids, steroids, saponins, tannins and flavonoids. The active compound that plays the most role is thought to be the flavonoid compound content.

Abstract

Forecasting the number of electricity customers is a crucial aspect of resource planning and management at PT PLN Tasikmalaya. One method that can be used to improve forecasting accuracy is Lagrange Interpolation, which constructs an interpolation polynomial based on known data points. Although this method has been widely applied in various fields, its use in forecasting the number of electricity customers remains rare. Therefore, this study aims to explore the application of the Lagrange Interpolation method in forecasting the monthly number of electricity customers at PT PLN Tasikmalaya.In this study, historical electricity customer data was used as the basis for constructing an interpolation polynomial, which was then utilized to forecast the number of customers from January 2024 to May 2024. The forecasting results indicate an increase in the number of electricity customers each month. After rounding, the estimated number of customers is 274,952 in January 2024, 278,142 in February 2024, 284,402 in March 2024, 296,031 in April 2024, and 316,391 in May 2024.The findings of this study demonstrate that the Lagrange Interpolation method can be applied to forecast the monthly number of electricity customers at PT PLN Tasikmalaya. However, to improve forecasting accuracy, it is recommended to compare this method with other forecasting techniques and consider external factors that may influence the number of customers, such as government policies, economic growth, and changes in electricity consumption patterns.

Abstract

This study aims to enhance students' critical thinking skills in Science learning at SMP Negeri 259 Jakarta through the utilization of the Class Point application. The research employs the Classroom Action Research (CAR) method conducted in three stages: pre-cycle, cycle I, and cycle II, with 35 eighth-grade students as the subjects. The results show that the use of Class Point significantly improved students' critical thinking skills, reflected by the increase in the class average score from 68.2 in the pre-cycle to 82.1 in cycle II. The students' engagement also increased from 55% in the pre-cycle to 89% in cycle II. Thus, the use of Class Point proves to be an effective alternative in enhancing students' critical thinking abilities in Science learning.
