The combustion of fossil fuels causes an increase in the release a group of gases found in the earth atmosphere that trap heat and contribute to the greenhouse effect, which in turn contributes to the occurrence of global warming. The advancement of sustainable energy sources plays an important role in human life due to renewable and environmentally friendly. This problem can be resolved by using alternative fuels as renewable sources of energy that are more environmentally friendly, such as bioethanol. Empty fruit bunches (EFB) constitute a portion of the solid waste that cause problems in storage, transportation, and processing costs. This is because EFB is waste in a solid that is produced from a processing facility where the fruits of the oil palm tree are processed to extract palm oil in large quantities. The process of producing bioethanol by utilizing coconut fruit bunches that are devoid of their contents as a raw material involves two essential stages: hydrolysis and drying. Hydrolysis with an acid catalyst results in a lower yield, but the catalyst itself is inexpensive. Conversely, when using enzyme catalysts, hydrolysis produces a greater quantity of reducing sugars. Enzyme catalysts can be employed in the simultaneous saccharification and fermentation (SSF) process using S. cerevisiae yeast, while chemical catalysts can be used in separate hydrolysis and fermentation (SHF) methods. The SSF method provides a comparatively elevated ethanol yield, demands less enzyme usage, has a shorter duration for ethanol production, and is environmentally friendlier when compared to the SHF procedure.

The rapidly evolving landscape of cryptanalysis necessitates an urgent and detailed exploration of the high-degree non-linear functions that govern the relationships between plaintext, key, and encrypted text. Historically, the complexity of these functions has posed formidable challenges to cryptanalysis. However, the advent of deep learning, supported by advanced computational resources, has revolutionized the potential for analyzing encrypted data in its raw form. This is a crucial development, given that the core principle of cryptosystem design is to eliminate discernible patterns, thereby necessitating the analysis of unprocessed encrypted data. Despite its critical importance, the integration of machine learning, and specifically deep learning, into cryptanalysis has been relatively unexplored. Deep learning algorithms stand out from traditional machine learning approaches by directly processing raw data, thus eliminating the need for predefined feature selection or extraction. This research underscores the transformative role of neural networks in aiding cryptanalysts in pinpointing vulnerabilities in ciphers by training these networks with data that accentuates inherent weaknesses alongside corresponding encryption keys. Our study represents an investigation into the feasibility and effectiveness of employing machine learning, deep learning, and innovative random optimization techniques in cryptanalysis. Furthermore, it provides a comprehensive overview of the state-of-the-art advancements in this field over the past few years. The findings of this research are not only pivotal for the field of cryptanalysis but also hold significant implications for the broader realm of data security.

This research aims to find out about sound and light materials. Researchers use qualitative research and this type of research is a descriptive method that groups people, an object, a condition, and an event. The descriptive method is a method that describes or analyzes a problem. Qualitative research is divided into 2, namely primary data through interviews and documentation, while secondary data through the books studied. The aim of this research is to analyze sound and light material which includes its properties and application in life. daily. The results of this research show that sound is a vibration that propagates as a wave through solid, liquid or gas media and sound is also defined as a series of waves of changes in density and sound pressure, while light is a wave that passes through a vacuum.

This activity aims to develop the potential for cultural literacy tourism in Padepokan Panji Asmoro Bangun Kedungmonggo Hamlet, Karangpandan Village, District. Pakisaji, Malang Regency. The service focuses on increasing the ability to equip Padepokan as a tourism destination for mask culture literacy.

Education is a process needed to obtain balance and perfection in the development of individuals and society. Education itself is faced with various problems that become obstacles to the quality of education itself. This can be seen in various aspects, some of which include the lack of adequate physical facilities such as the feasibility of buildings used in the learning process. These problems can hinder the development of students to reach their best potential and cause inequality in terms of access to quality education. There are differences in the quality of education in rural and urban areas, where rural areas have more specific challenges such as lack of school facilities, difficulty of access, and technological and social changes. In the context of education, technology has changed the way we learn, access information and communicate. Social changes, such as changing demographics, can also affect the way we design education systems. These factors create pressures on education that require creative thinking and innovative solutions. This research uses qualitative research methods through a phenomenological approach. The theoretical foundation used in this research is the functional structural theory proposed by Talcott Parson. Data collection in this study used interviews, observation, and documentation.
 

Money Politics is an attempt to bribe voters by providing money or services so that voters' vote preferences can be given to a briber. Political money is no longer surprising, it is a common thing that happens when it comes to elections, parties do various things to get votes from the people, this political money has been passed down from generation to generation. Violations that often occur during elections include the widespread practice of money politics. Money politics is considered a practice that injures democracy. Elections are a big party in democracy where every citizen is free to give their voting rights to the parties that are nominating. In the lead up to the election, many candidates are chosen by the party to take part in the community by giving gifts. This is what we often refer to as "Money politics", this cannot be avoided, because of this people become unstable in their choices. The aim of this research is to find out the political challenges in general elections, find out what factors cause the practice of money politics in general elections and to find out how to face these political challenges. The research method used by the author is a qualitative method, which is descriptive research and tends to use analysis. The aim is to explain a phenomenon in as much depth as possible by collecting data in as much depth as possible, with greater emphasis on the depth of the data obtained. Students have an important role in fighting money politics. As students who study politics, it is only natural that they can form public awareness by providing political education or education for the community or others around us about the importance of integration in politics, and encouraging transparency and accountability in general elections and so that they are more aware of the dangers of money politics so that with Education to the public will increase people's understanding of the dangers of money politics and they will be wiser in choosing a good and wise leader. And society will not be more easily influenced by using political money. By getting involved in anti-money politics campaigns and fighting for policies that reduce corruption and the influence of money in politics, students can help create a more just and democratic political system.
