Soil fertility is an important element in agricultural sustainability, especially in supporting plant growth. One natural way to increase soil fertility is through Biological Nitrogen Fixation (FNB) by Rhizobium bacteria. These bacteria have a symbiotic relationship with legume plants, forming root nodules that convert atmospheric nitrogen into compounds that plants can absorb, such as ammonium (NH4+). The purpose of this article study is to determine the potential of Rhizobium bacteria in increasing and efficiency of nitrogen fixation which has an impact on soil fertility and increasing plant productivity. This study adopts a library research method or approach, which involves a series of systematic activities, starting from collecting data through various library sources, reading in depth, recording important information, to processing the research materials. The study results show that Rhizobium can reduce dependence on chemical fertilizers, increase soil fertility, and produce growth hormones that support nutrient absorption. These findings emphasize the important role of Rhizobium in supporting sustainable agriculture, especially in tropical regions where access to synthetic fertilizers is minimal.

The use of fertilizer in plant cultivation is basically carried out to meet the availability of nutrients for plants in order to obtain optimal results. However, excessive use of fertilizer can actually have a negative impact on the ecosystem, such as environmental pollution and decreasing soil quality. The use of biofertilizer as a substitute for biological fertilizer is an alternative that can be used to reduce dependence on chemical fertilizers. Biofertilizer is a biological fertilizer containing various live microorganisms which is used to increase plant productivity by improving the quality of soil fertility. One of the microbes that acts as a biofertilizer is the Bacillus sp. The purpose of this article is to find out how Bacillus sp. functions as a biological fertilizer that can increase soil fertility and increase crop productivity. Bacillus is a genus of bacteria that can be used as a biofertilizer because of its more varied antagonistic mechanisms and ability to produce endospores. The method used in this article is a meta-analysis or literature review method in several journals published online which are integrated with Google Scholar.

Regional Head Elections (Pilkada) are a manifestation of people's sovereignty and the implementation of democracy in Indonesia, as stipulated in the 1945 Constitution. This study examines the role of the Constitutional Court (MK) in resolving disputes over regional election results. The method used is normative juridical legal research, analyzing relevant regulations and literature. The MK holds permanent authority to adjudicate Pilkada disputes, replacing the Supreme Court. The impact of MK's decisions includes the implementation of Re-voting (PSU), which strengthens the legitimacy of Pilkada results and influences local political stability. However, challenges such as the complexity of evidence and reliance on the MK highlight weaknesses in the oversight system.  

Social media has changed the way people communicate and share information, opening up great opportunities as well as challenges such as hoaxes and polarization. In Indonesia, these platforms have become important spaces for public discussion, especially in politics. Wise management is needed for social media to support transparency, accountability and democracy. The purpose of this study is to analyze the role of social media in constitutional dispute resolution, identify challenges that arise, and provide recommendations for wise management so that social media can support transparency, accountability, and democratic principles. This research uses a normative method. Social media has a major role in constitutional disputes, both as a tool for information dissemination and a space for public discussion. On the one hand, social media helps transparency, participation, and community mobilization in constitutional issues. However, on the other hand, it also poses challenges such as disinformation, hoaxes, and political polarization that can escalate conflicts. Regulation and supervision are needed to address the misuse of social media without compromising freedom of expression. Digital literacy education is also important to encourage responsible use of social media, so that it can be a tool to support democracy and peaceful dispute resolution. Social media can worsen the political situation through hoaxes and hate speech. Therefore, clear regulations are needed to prevent abuse without reducing freedom of speech. Policy reforms that balance surveillance and freedom of expression are important, with collaboration between the government, platforms and communities to create a safe digital space. Digital literacy also needs to be improved so that people can sort out information and support political stability.

This study examines the use of language in the lyrics of "Bukti" by Virgoun as a means of expressing and communicating emotions deeply. Applying Ferdinand de Saussure's semiotic theory, the research focuses on how linguistic elements such as metaphor, simile, and personification are employed to respond to and depict emotional experiences related to themes of love and devotion. Document analysis method was employed to investigate the structure and meaning content in the song lyrics, identifying emerging themes and the complex relationships among textual elements. Findings reveal that "Bukti" not only conveys profound messages about the complexities of human emotions in romantic relationships but also presents meanings that resonate deeply with listeners through simple yet nuanced language. The implications of this study significantly enrich our understanding of the role of music as a powerful medium for expressing and communicating the essence of human emotions universally. This research contributes to deepening insights into the language in song lyrics as a form of artistic expression that influences and enriches human experiences broadly.

This research discusses the use of code-mixing in the lyrics of the song “Now I Know” by Kaleb J. Code-mixing, in the form of the insertion of English elements into Indonesian lyrics, often appears in modern music as a response to globalization. A qualitative research approach is used to identify the forms of code-mixing (words, phrases, and clauses), its function, and its impact on the song's message. The results of the analysis show that code-mixing dominates the chorus with English to accentuate emotional intensity, while Indonesian is present in the verses to provide a narrative that is familiar to local listeners. The use of two languages reflects a balance between local and global elements, enhancing the musical aesthetics and international appeal of the song. Intercoding acts as a linguistic and artistic tool that expands the range of listeners, supports the themes of love and regret, and strengthens pop music's connection to globalization trends.
