In the automotive sector, which produces over 60-70% of global pollution emissions, the world faces difficulties in making the switch from fossil fuels to environmentally friendly renewable energy sources. Technology has advanced significantly, and companies such as Toyota and FiA are working to improve competitiveness and attract more manufacturers to produce hybrid cars. Reducing environmental impact and greenhouse gas emissions is the goal of the Formula 1 project, which partners with ARAMCO, one of the world's largest mining companies. Using the methodology of reviewing literature on energy-efficient fuels and adapting to Formula 1 vehicle regulations, with a special emphasis on hybrid strategies, to achieve net zero emissions by 2050. Research on the use of synthetic materials in fuels such as ethanol, ethanol, butanole, dimethyl methacrylate (DMM), and oxymethylethyl (OME) 3-5 has shown promising results in reducing greenhouse gas emissions. The transition to renewable energy sources is essential to reduce global pollution.

Students are required to memorize tashrif in the Shorof course, because tashrif is the main basis in understanding the structure of the Arabic language, especially in word formation and change. Mastery of tashrif helps students recognize the patterns of word changes from roots to derivatives, which is very important for understanding religious texts such as the Qur'an, Hadith, and classical books. In addition, this ability improves reading, writing and speaking skills in Arabic. By memorizing tashrif, students are also more confident in using Arabic actively, both in academic and practical contexts. Therefore, tashrif is an important part of Arabic language learning that not only facilitates text comprehension, but also builds language skills.This study aims to analyze the effect of the singing method on the ability to memorize tashrif in the Shorof course of class 5B students of class 2022. using quantitative approach research with data collection through questionnaires filled out by 28 students. The data obtained were analyzed using descriptive statistics to see the tendency of the influence of the singing method on memorizing tasrif. The use of this singing method is very helpful in improving students' memory in memorizing tasrif. In addition, students consider this method fun and motivate them to be more active in learning.

The Constitution is the fundamental foundation for the establishment and development of an independent state, reflecting the framework of a democratic and just political life. As an integral part of the constitutional system, the Constitutional Court (MK) plays a crucial role in safeguarding justice and democracy through its oversight and constitutional interpretation functions. The Constitutional Court in Indonesia functions as a guardian of the constitution, ensuring that all components of the state and society consistently implement the constitution. Indonesia's constitutional history shows significant dynamics of change, with the 1945 Constitution undergoing various amendments before finally being reaffirmed in the reform era. The establishment of the Constitutional Court in 2003 reflected the spirit of reform to guarantee human rights and the rights of citizens that had previously been neglected. With a special task in handling constitutional cases, the Constitutional Court aims to maintain government stability and overcome the problem of multiple interpretations of the constitution that occurred in the past.

Law No. 19 of 2013 on the Protection and Empowerment of Farmers aims to improve farmers' welfare through various programs, including fertilizer subsidies. However, the distribution of subsidized fertilizers often faces issues such as misallocation, delays, and misuse. The Farmer Card (Kartu Tani), an innovation to facilitate the distribution of subsidized fertilizers, has significant potential to address these problems. This study aims to evaluate the effectiveness of the Farmer Card in the distribution of subsidized fertilizers, identify the challenges faced by farmers in its use, and propose solutions for the optimization of the Farmer Card. Using a descriptive qualitative approach through literature review, this study finds that the main challenges include technical issues, lack of socialization, bureaucratic hurdles, and farmers' distrust of new technology. Proposed solutions include enhancing technological infrastructure, providing intensive training for farmers, and simplifying administrative procedures. The study's results indicate that improvements in these aspects can enhance the effectiveness and transparency of subsidized fertilizer distribution through the Farmer Card.

This study aims to examine the contribution of historical science in the effort to revitalize museums as educational institutions and preserve cultural heritage. Museums, as public spaces that store and exhibit historical collections, have an important role in facilitating public understanding of the nation's history. However, in the context of the development of the times and changes in public preferences, museums often face challenges in attracting visitors. The contribution of historical science in museum revitalization includes a more interactive approach, technology integration, and storytelling based on in-depth historical research. Thus, historical science not only functions as a source of information, but also as a basis for creating educational experiences that can connect the current generation with relevant historical values. This study suggests various revitalization strategies that can be applied to increase the attractiveness and function of museums as centers for learning and preserving culture, as well as strengthening historical awareness.

This study aims to analyze the relationship between the use of social media and sleep quality in FEBI students. This study uses an analytical observational research design with a cross sectional approach. Data was collected using a questionnaire consisting of information about social media usage and sleep quality. The results showed that there was a weak correlation between social media use and sleep quality (?=0.004, R=0.506). This shows that excessive use of social media can interfere with the quality of students' sleep

Ikan neon adalah spesies ikan cantik yang populer, terutama di kalangan penggemar aquascape. Terdapat dua jenis ikan neon yaitu ikan neon tetra dan ikan kardinal yang masing-masing memiliki pola sisik yang berbeda, ikan neon tetra memancarkan kilatan warna biru dan neon merah yang memanjang dari pusat tubuh hingga ke bagian bawah otak. dan ikan neon cardinal memiliki lampu berwarna biru dan merah dari pangkal ekor hingga kepalanya. Namun, spesies ikan seringkali memiliki bagian tubuh, sirip, dan ekor yang mirip, sehingga sulit untuk mengidentifikasi spesies tersebut. Karena keterbatasan kemampuan mata manusia untuk membedakan ikan tetra dari neon kardinal, peneliti mengklasifikasikan ikan neon menggunakan teknik ekstraksi fitur Gray Level Co-occurrence Matrix (GLCM) dan Extreme Learning Machine (ELM) untuk membedakannya. Dataset citra yang dihasilkan adalah untuk mendapatkan nilai x dan y dari fungsi GLCM dengan membuat 1.915 sampel citra yang terdiri dari 954 citra Neon Tetra dan 961 citra Neon Tetra, dilanjutkan dengan 700 data latih dan 300 dataset uji. Didapatkan efisiensi 97,90% dan nilai Loss 2,10% pada penelitian ini menunjukkan hasil akurasi yang sangat baik.
