Gunungsari Village, Windusari District, is one of the areas facing quite serious challenges in efforts to develop basic literacy in school-age children. The main problems faced are low interest in reading, limited access to adequate reading materials, and learning methods that are still conventional. These conditions have implications for many children who are not able to read and write fluently despite having received an elementary school education. In response to this situation, the community service team took the initiative to implement a literacy program that uses an interactive learning approach through the development of a literacy park. This program is not only designed to be a learning platform, but also to create a learning atmosphere that is fun, contextual, and involves the active participation of children. Various activities are implemented, including storytelling, the provision of a reading corner, educational games such as math games, vocabulary quizzes, and the provision of simple rewards to maintain high learning motivation. This program activities are carried out periodically with the involvement of the school, the surrounding community, and also the village government, so that its sustainability has the support of various parties. The results of the implementation show a significant increase in children's literacy skills. Not only are they reading more fluently, but they are also better able to comprehend story content and write simple ideas. Furthermore, the children appear more confident in expressing themselves, are more active in every learning activity, and are beginning to demonstrate positive reading habits. A culture of literacy is also slowly growing through the existence of child-friendly and inclusive literacy parks. This proves that a fun, community-based literacy approach is highly relevant in rural areas with limited resources and can be a simple yet impactful means of educational transformation for children's futures.

The low level of reading literacy in remote areas, such as the Muna Barat Daya Regency, poses a significant challenge in basic education. One innovation proposed to address this issue is the implementation of Scramble Fun Learning, an educational game-based approach designed to enhance reading literacy skills in students at SD Negeri 1Weet. This community service activity was carried out in two stages: a theoretical stage, which provided foundational understanding about the importance of literacy and gamification approaches, and a practical stage involving both teachers and fifth-grade students in word arrangement activities. Scramble Fun Learning combines game elements with a gamification approach by having students arrange words from random letters. The main objective is to train vocabulary recognition, strengthen reading comprehension, and increase student motivation to learn. In this activity, students are challenged to form words or sentences within a limited time, which not only stimulates their creativity but also makes the learning process more enjoyable and engaging. This method enables students to learn while playing, which is particularly effective in overcoming the boredom that often occurs in conventional learning. The results of this activity showed a significant improvement in student enthusiasm, active participation, and literacy skills. Many students who were previously disinterested in reading activities became more enthusiastic and motivated. Despite limitations in resources and time, the activity was still effectively implemented, thanks to creative adjustments made by the implementing team to ensure the material and activities were well received by both students and teachers. Overall, these findings indicate that Scramble Fun Learning is a highly potential and applicable approach to improving students' reading literacy, especially in areas with limited educational resources. This approach not only enhances literacy skills but also builds students' interest and motivation to continue learning.

In general, attacks on hospitals are prohibited under international humanitarian law (IHL), which aims to protect the life and health of civilians during armed conflicts. However, in certain circumstances, hospitals may lose their protection and thus become legitimate targets in warfare if they are considered to be involved in military activities or supporting the parties to the conflict. This brings into question the application of the principle of proportionality, which is an essential element of IHL. The principle of proportionality seeks to balance military necessity with the protection of civilians, requiring that the harm caused by military operations should not be disproportionate to the military advantage sought. This principle demands that military operations be conducted carefully to minimize harm to civilians and civilian objects, including hospitals. However, its application raises significant ethical questions regarding the moral justification of such actions, especially when hospitals are targeted in attacks. One prominent example that raises ethical concerns about this justification is the destruction of Al-Shifa Hospital in Northern Gaza. The hospital was destroyed in an airstrike during the conflict, causing severe harm to the civilian population that relied on this facility. While the principle of proportionality is designed to limit damage, attacks on hospitals such as Al-Shifa raise questions about whether the actions taken were truly consistent with this principle, particularly when the military gain achieved does not seem to outweigh the damage caused to human life and vital infrastructure. This article aims to explore the conventional moral justification of the principle of proportionality in international humanitarian law and evaluate its application in the case of Al-Shifa Hospital, challenging the boundaries of the principle in practice.

Acute Respiratory Infection (ARI) is a disease that attacks the respiratory system and is classified as an infectious disease. This disease can be caused by various types of microorganisms such as viruses, bacteria, or fungi, but most cases of ARI are caused by viral infections. ARI includes conditions such as the common cold, bronchitis, pharyngitis, and pneumonia. In developing countries, ARI is a leading cause of death, especially in children under the age of five. Lack of access to health services, poor sanitation, and malnutrition are factors that contribute to this condition. Therefore, efforts to prevent and treat ARI are crucial, both through conventional and alternative medicine. One herbal plant that has long been used in complementary therapy for ARI is Echinacea, which comes from the flowering plant Echinacea purpurea and is native to the United States. Echinacea is believed to have immunostimulant properties, meaning it can stimulate the immune system, thereby helping to prevent and accelerate the healing of upper respiratory tract infections. Several studies have shown that the use of Echinacea can reduce the duration and severity of ARI symptoms, as well as reduce the risk of recurrent infections. However, research findings on the effectiveness and safety of Echinacea continue to show significant variation. Some clinical trials report significant benefits, while others find no significant effect compared to placebo. Therefore, a systematic review aims to gather the latest evidence regarding the effectiveness and safety of Echinacea in the treatment and prevention of acute respiratory infections (ARI). This approach is expected to yield stronger and more reliable conclusions to support the use of Echinacea as a safe and effective alternative therapy.

In the digital era, conventional media such as radio face significant challenges due to shifts in media consumption behavior, particularly among urban youth who prefer digital platforms and social media. Jak 101 FM has adapted by utilizing Instagram digital media in an off-air program titled “Jak After School” to reach a broader audience and build a positive image. This study examines the public relations strategy of Jak 101 FM in managing Instagram as part of promotion and image enhancement using descriptive qualitative methods and Chris Heuer's 4C theory (context, communication, collaboration, and connection). Research findings show that Jak 101 FM's public relations strategy involves creative content production, utilization of Instagram's interactive features, collaborating with local communities and influencers, and building emotional connections with audiences. The “Jak After School” program become an effective medium that strengthens audience loyalty and maintains Jak 101 FM's existence amid digital media industry competition.

This study aims to determine the effect of using educational gim-based learning media on students' math learning outcomes on the material of Linear Equation One Variable (PLSV). The background of this research is the low student learning outcomes in conventional math learning which is considered less interesting, especially in PLSV material which is abstract. This study used a quantitative approach with a quasi-experimental design and a nonequivalent control group design. The sample consisted of two classes, namely the experimental class (using educational gim media) and the control class (using conventional methods), which were taken from VII grade students of MTs Ra’iyatul Husnan, Wringin Bondowoso. The research instrument was in the form of pretest and posttest tests that had gone through validity and reliability tests. The pretest results showed that both classes had relatively balanced initial abilities. However, in the posttest, the learning outcomes of experimental class students showed a more significant increase than the control class. The data were analyzed using normality, homogeneity, and Mann-Whitney U Test hypothesis tests because the posttest data were not normally distributed. The analysis results showed a significance value of Asymp. Sig. (2-tailed) significance value of 0.000 <0.05, which means there is a significant effect of using educational gim media on student learning outcomes. This finding shows that interesting and interactive learning media such as educational gims can improve students' motivation, understanding and learning outcomes in mathematics. Therefore, the use of educational gims is recommended as an innovative alternative in learning mathematics, especially on material that is abstract and difficult for students to understand.

This study aims to investigate the sensory characteristics and nutritional content of macarons with the addition of kecombrang flower essential oil (Etlingera elatior). The research was conducted to determine the effects of various concentrations of kecombrang flower essential oil (3%, 5%, and 7%) on macaron quality. The sensory attributes evaluated included color, aroma, taste, texture, and overall preference, while nutritional analysis focused on key macronutrients such as carbohydrates, sugar, fat, protein, and ash content. The sensory evaluation utilized a single-factor ANOVA and Duncan's multiple range test to compare the effects of the different concentrations of essential oil. The results indicated that the addition of 5% kecombrang essential oil yielded the most favorable sensory scores, with the highest ratings in color (4.20) and texture (4.29). Furthermore, aroma and taste were rated highly, confirming that this concentration enhanced the overall quality of the macarons. Although the likeability score did not show significant statistical differences between treatments, all treatments were generally categorized as “liked” by the panel. For the nutritional content analysis, the macaron sample with 5% essential oil was selected for testing through a proxy method. The results indicated that the macaron had a carbohydrate content of 46.31%, sugar content of 31.62%, fat content of 3.05%, protein content of 19.08%, and ash content of 0.14%. These findings are noteworthy, as the macaron with kecombrang flower essential oil showed lower carbohydrate and fat content compared to a typical macaron, while it exhibited higher protein content. These results suggest that macarons with kecombrang essential oil may offer a healthier alternative to conventional macarons, particularly for those seeking lower sugar and fat content in their diet.

This study examines the philosophy of Islamic economics and the legal principles underlying the implementation of the mudharabah muqayyadah contract in Islamic financial institutions. The mudharabah muqayyadah contract is a form of partnership contract involving the shahibul maal (capital owner) and mudharib (business manager), with provisions limited to a certain scope, so that the implementation of this contract must be based on sharia principles that regulate all forms of financial transactions. This study focuses on how ethical values in Islam are integrated with the legal principles of sharia contracts, particularly in maintaining fair relations between the two parties. Through a normative qualitative approach, data were collected from classical and contemporary literature as well as regulations applicable in the Islamic financial sector. The results show that the mudharabah muqayyadah contract is a manifestation of maqashid al-shariah in economic practice, which aims to safeguard assets, uphold justice, and create balance in economic transactions. The legal principles applied in this contract include freedom of contract, good faith, and fairness, which serve to ensure transparency, accountability, and justice between the parties involved. However, the biggest challenges in implementing the mudharabah muqayyadah contract are the aspects of supervision and compliance with sharia principles, as well as technical practices that are often influenced by conventional systems. Therefore, this study recommends the need to strengthen education on sharia philosophy for practitioners in the Islamic financial sector, as well as the need for regulatory harmonization to ensure the fair implementation of the contract, in accordance with the transcendental values taught in Islam. Furthermore, harmonization of regulations governing the mudharabah muqayyadah contract is also crucial to create uniformity in practice across Islamic financial institutions. Clear and firm regulations will reduce the potential for misinterpretation that can lead to bias against the interests of one party.

This study is motivated by the difficulty students face in understanding the concept of food chains, which is attributed to the conventional teaching methods still in use. Therefore, the researcher believes that the application of a new teaching model is expected to enhance student engagement in the teaching and learning process, ultimately improving learning outcomes. Natural Science is often considered difficult because of its many theories and the lack of variation in teaching methods, leading to poor student performance. Given these issues, an innovative teaching model is necessary. The aim of this study is to examine the impact of the Problem-Based Learning (PBL) model on students' knowledge in the Natural Science subject. The research method used is an experimental method with a quasi-experimental design. The study population consists of 50 fifth-grade students, with 25 students in the experimental group and 25 students in the control group. The hypothesis tested is that there is an effect of the Problem-Based Learning model on Natural Science learning outcomes. The results of the study show that the Problem-Based Learning model has a significant effect on students' knowledge. This is evidenced by the t-test results, which show a t-value of 12.400, greater than the t-table value of 2.01. Therefore, it can be concluded that the Problem-Based Learning model positively affects the understanding of food chain concepts in fifth-grade students. The findings of this study are expected to be beneficial for teachers in improving the quality of their teaching, for students to better understand the material through more engaging methods, and for the school environment in developing innovative and effective teaching practices.

The rise in motor vehicle theft cases in various regions indicates the weakness of the security systems implemented by most users. Systems such as manual locks and alarms often fail to prevent crime, either because they are easily hacked conventionally or due to user negligence in their operation. In today's technological era, a system is needed that is not only secure, but also intelligent and practical. One promising solution is the implementation of a facial recognition-based security system. This study aims to design and test a vehicle security simulation system using facial recognition technology integrated with Arduino Uno and MATLAB. This system utilizes a laptop camera to capture the user's facial image, then performs a detection and verification process using the FaceNet algorithm. If the face is recognized and verified with data stored in the database, the Arduino will activate the actuator components in the form of a DC motor to simulate starting the engine, and a servo motor to simulate opening the vehicle door. This study uses a quantitative experimental approach to analyze the effect of variations in distance (30, 40, and 50 cm) and lighting brightness levels (10–20, 21–30, and 31–40 lux) on the system's response time. A total of 27 combinations of conditions were tested, and the data obtained were analyzed using Microsoft Excel and ANOVA tests in Minitab software. The results of the analysis showed that the optimal response time was obtained at a distance of 40 cm with a medium level of illumination (21–30 lux). In addition, both distance, brightness, and the interaction between the two factors were shown to have a significant effect on the system's response time (P-Value < 0.05). These findings indicate that the system is quite sensitive to environmental changes, so further testing is highly recommended, especially to measure the actual delay, the detection error rate, and the development of a more robust face detection algorithm so that the system can be used reliably in various lighting conditions and face capture angles in the real world.

The rapid development of the smart city concept encourages the need for energy management that is more efficient, sustainable and adaptive to the needs of modern urban communities. In this context, renewable energy is the main solution to reduce dependence on fossil energy sources that are limited and pollute the environment. This research aims to optimize the utilization of renewable energy in smart cities by integrating Big Data technology and Decision Support Systems (DSS). The approach used in this research is a case study and system modeling method, which involves collecting energy data from various sources such as IoT sensors, weather stations, and energy distribution systems in real-time. The data is then analyzed using Big Data Analytics techniques to identify energy consumption patterns, potential renewable energy production, and peak load predictions. Furthermore, a decision support system was designed to assist policy makers and city managers in determining optimal energy distribution and usage strategies based on the available data and simulations. The results show that the integration of Big Data and DSS is able to increase the efficiency of renewable energy utilization up to 25% compared to conventional systems. In addition, the system is also able to dynamically respond to changing conditions and provide more accurate and adaptive decision recommendations. These findings indicate that the synergy between data technology and decision support systems plays a strategic role in creating sustainable and environmentally sound smart cities.

Public Fuel Filling Stations (SPBU) are important facilities that provide various types of fuel such as gasoline, diesel, and Pertamax to meet the needs of motorized vehicles. The existence of SPBU greatly helps the public in obtaining fuel at a more economical price compared to purchasing retail. However, the transaction system at SPBU generally still uses conventional methods, such as cash payments or the use of debit/credit cards that have not been fully integrated with an efficient digital system. The use of RFID (Radio Frequency Identification) technology has been implemented as a non-cash transaction method at several SPBUs, but this system still has various weaknesses, such as limited device compatibility and delays in transaction processing. This prompted the author to develop the concept of an independent SPBU based on modern technology that is more efficient and secure. The proposed innovation includes the use of contactless smart cards and coin acceptors for the payment system, allowing users to make self-service transactions without operator involvement. In addition, the author also added several supporting components such as proximity sensors, which function to detect the presence of vehicles or people around the SPBU area. These sensors can help in saving electrical energy by activating the system only when needed. Another component is a vibration sensor, which plays a crucial role in detecting excessive vibrations that could potentially cause leaks. If excessive vibration is detected, the system automatically closes the solenoid on the pump to prevent the risk of fire or damage. By integrating this technology, the autonomous gas station system is expected to improve operational efficiency, user convenience, and safety during the automatic refueling process. This development is expected to be an innovative solution for modernizing the gas station system in Indonesia.

Epilepsy is a chronic neurological disorder characterized by recurrent seizures due to abnormal electrical activity in the brain. This condition can significantly impact the quality of life of sufferers, making the development of effective and safe anticonvulsant therapies a priority in pharmacological research. This study aimed to evaluate the effectiveness of various anticonvulsant drugs, including herbal candidates, in a mouse model (Mus musculus) using acute and subchronic test protocols. Seizures were induced by administering strychnine, a glycine receptor antagonist that triggers excessive neuronal excitability. Parameters observed included seizure onset (the time from strychnine administration to the onset of the first seizure) and deadtime (the time of survival after a seizure). The study involved six treatment groups: a negative control (Na-CMC), four conventional drug groups (phenytoin, diazepam, pregabalin, and gabapentin), and one herbal candidate group made from Polyalthia longifolia (glodokan tiang). The results showed that most treatment groups were able to delay seizure onset and significantly prolong deadtime compared to the negative control. Statistical analysis using ANOVA yielded a p-value <0.05, indicating a significant difference between groups. The herbal candidate Polyalthia longifolia showed promising anticonvulsant potential, although it did not fully match the effectiveness of conventional drugs such as phenytoin or diazepam. The negative control (Na-CMC) showed the fastest onset and shortest survival time, reflecting the absence of a protective effect against seizures. This study emphasizes the importance of further testing using chronic protocols and evaluating additional parameters such as plasma drug concentrations and neurological side effect profiles. The obtained data are expected to form the basis for the development of anticonvulsant therapies based on a combination of modern drugs and natural ingredients, with the hope of producing safer, more effective treatment alternatives, and potentially reducing dependence on long-term synthetic drugs.

Improving the quality of biology learning in secondary schools requires pedagogical innovations that connect academic content with real-life contexts and leverage digital technology. This study aims to analyze the effect of a contextual teaching approach assisted by interactive PowerPoint on students’ learning outcomes in the human respiratory system topic. A true experimental design with a pretest–posttest control group was employed at SMA Negeri 1 Langowan, involving two eleventh-grade classes selected through simple random sampling. The experimental class received contextual instruction integrated with interactive PowerPoint, while the control class was taught using conventional methods. Data were collected through validated achievement tests and analyzed using normality and homogeneity tests, followed by independent and paired t-tests. The results indicate a significant improvement in learning outcomes for students in the experimental class compared to the control group. The experimental group’s posttest scores were substantially higher, and the difference was statistically significant. Integrating a contextual approach with interactive visualization effectively enhanced students’ understanding of abstract biology concepts, promoted active participation, and strengthened learning motivation. These findings support constructivist theory and highlight the relevance of contextual teaching in science education aligned with the Merdeka Curriculum. The study implies the importance of implementing context-based strategies combined with simple digital media to improve biology learning effectiveness. Future research may explore its impact on non-cognitive skills such as critical thinking and scientific attitudes. Furthermore, the results of this study provide opportunities for teachers to be more creative in designing teaching materials that are not only informative but also interactive and relevant to students' lives. By utilizing media such as interactive PowerPoint, teachers can present complex biological content in a more engaging and understandable way.

This community service activity was conducted in Sawahan Hamlet, Mojotengah Village, Kedu District, Temanggung Regency, with the primary objective of enhancing the health and productivity of sheep through the introduction and production of mineral block molasses as supplementary feed. Mineral block molasses is a nutrient-rich feed supplement designed to meet the mineral requirements of ruminants, particularly sheep, which are often not fully met by conventional forage. The program was implemented using a participatory method, beginning with a lecture session that provided theoretical knowledge regarding the benefits, composition, and formulation of mineral block molasses. This was followed by an interactive discussion session in which participants, mainly local sheep farmers, were encouraged to share challenges and constraints they face in livestock feeding management. The facilitators then provided practical problem-solving approaches tailored to the local context. The final stage involved a hands-on demonstration of the step-by-step process of producing mineral block molasses, enabling participants to observe and practice directly. The results of this activity showed that participants not only gained new knowledge about the nutritional importance of mineral supplementation but also developed the practical skills necessary to independently produce mineral block molasses for their livestock. This is expected to improve feed efficiency, promote better animal health, and increase livestock productivity. Furthermore, the activity fostered community awareness of sustainable livestock management practices and the economic benefits of producing feed supplements locally. In conclusion, this program successfully empowered the local farming community with both theoretical and practical competencies in mineral block molasses production, contributing to improved livestock performance and farmer welfare. The continuation of such initiatives is recommended to ensure long-term adoption and optimization of livestock feeding practices in the region.

Advances in digital technology have brought significant changes to various aspects of life, including socio-economic activities such as arisan (social gathering). Arisan, which was previously conducted conventionally, has now begun to transform into online arisan. This change offers several advantages, including ease of access, reduced time constraints, and a wider range of participation. However, behind this convenience, an equally important challenge lies the lack of regulation and oversight of online arisan practices, which are prone to legal threats. This study aims to examine the urgency of creating written agreements in the implementation of online arisan and examine their legal force as a form of legal protection for the actors, both organizers and members. Using a normative juridical method through a regulatory-statutory approach and case studies, this study emphasizes the importance of legal validity in civil relations formed through online arisan. Data were obtained through observation, interviews, and documentation, which were then analyzed through a process of data reduction, presentation, and drawing conclusions. The results of the study indicate that written agreements in online arisan have legally binding force as long as they meet the requirements for a valid agreement according to Article 1320 of the Civil Code. The existence of a written agreement can increase legal certainty, strengthen the legal standing of the parties, and serve as valid evidence in the event of a breach of contract. Therefore, creating a written agreement is crucial to avoid losses and strengthen legal protection in online arisan (social savings and credit) practices. Furthermore, a written agreement also reflects the good faith of the parties in carrying out their commitments professionally and responsibly. This serves as an important foundation for building trust and creating a transparent and accountable online arisan system. Therefore, it is recommended that every online arisan participant create a clear written agreement and have it notarized to strengthen its legality.

Indonesia is recognized as one of the world’s richest countries in terms of biodiversity, including a wide variety of traditional medicinal plants. One of the lesser-known yet promising local species is matoa (Pometia pinnata J.R. Forst & G. Forst), whose leaves have been traditionally used by local communities to treat various ailments, including diarrhea and seizures. This study aims to investigate the pharmacological effects of matoa leaf extract, with a particular focus on its anticonvulsant activity, while also reviewing its potential chemical constituents as a basis for herbal medicine development. The research was conducted using a combination of literature review and experimental testing on mice (Mus musculus) induced with strychnine to trigger seizures. Key observed parameters included seizure onset time and survival duration (dead time) following the administration of either synthetic drugs or matoa leaf extract. The results demonstrated that the matoa leaf extract exhibited significant anticonvulsant effects, as indicated by prolonged seizure onset and increased survival time in test animals. These pharmacological effects are presumed to be related to the presence of active compounds such as flavonoids, tannins, and alkaloids, which may contribute to the stabilization of the central nervous system. Compared to conventional synthetic anticonvulsants, matoa leaf extract may offer a safer, plant-based alternative with potentially fewer side effects. The findings of this study provide valuable scientific evidence supporting the potential of Pometia pinnata leaves in the development of Indonesian herbal phytopharmaceuticals. Furthermore, they highlight the importance of further research, including preclinical and clinical trials, to validate efficacy, determine optimal dosages, and ensure safety for human use.

This study aims to compare the financial performance of Islamic banks and conventional banks operating in Jambi Province during the 2021–2023 period. The approach used is comparative quantitative, with descriptive analysis and independent sample t-tests. Five key financial ratios were analyzed in this study: Return on Assets (ROA), Return on Equity (ROE), Operating Expenses to Operating Income (BOPO), Net Interest Margin (NIM), and Loan to Deposit Ratio (LDR). Data were obtained from the quarterly financial reports of each sample bank, thus reflecting actual financial performance on a periodic and ongoing basis. The analysis shows significant differences in three key financial ratios: ROA, ROE, and BOPO. Conventional banks demonstrate higher levels of profitability and operational efficiency than Islamic banks. High ROA and ROE values reflect the effectiveness of conventional banks in generating profits from their assets and capital. Furthermore, lower BOPO ratios in conventional banks indicate a better ability to control operating costs. In contrast, no significant differences were found in the NIM and LDR ratios, indicating equality between the two types of banks in generating interest margins and disbursing credit or financing to customers. This finding has important implications for the development of the Islamic banking sector to be more competitive, particularly in terms of efficiency and profitability. Islamic banks are expected to improve their asset and operational management strategies to increase competitiveness amidst the dual banking system in Indonesia. This research also contributes to regulators in formulating policies that support the growth of Islamic banks in the regions. For academics and practitioners, this study broadens understanding of the dynamics of local banking financial performance and serves as a reference for further research on the effectiveness of the dual banking system in the regional context.

This study aims to analyze the differences in various extraction techniques and their relationship to the yield and biological activity of phytochemical compounds from natural materials. The research was conducted through a systematic literature review from various reliable scientific sources over the last decade. The results indicate that extraction methods such as maceration, soxhlet extraction, microwave-assisted extraction (MAE), and ultrasound-assisted extraction (UAE) have varying effectiveness. The effectiveness of these methods is highly dependent on the type of material, solvent used, and process parameters such as temperature, time, and solvent-to-material ratio. Modern extraction methods such as sonication, MAE, and UAE tend to produce higher yields and better biological activity. These modern methods have the advantage of being more time-efficient and requiring fewer solvents, thus allowing the extraction of active compounds more optimally. Additionally, technologies like microwave and ultrasonic waves help break down the cell walls of natural materials, enhancing the release of phytochemical compounds more effectively and rapidly. However, conventional methods such as maceration and soxhlet extraction remain relevant, especially for materials containing thermolabile compounds that may degrade at high temperatures. These methods are still preferred to maintain the stability of active compounds sensitive to thermal degradation. Choosing the appropriate extraction method is crucial in producing high-quality extracts that can potentially be used as raw materials for phytopharmaceuticals, supplements, or other natural products. This study provides a strong theoretical foundation for further experimental research and guidance in selecting extraction methods based on the required efficiency and effectiveness for industrial applications. Thus, this study contributes to the development of more efficient and high-quality natural products.
