This study analyzes the symbolic meaning in the lyrics of the song "Halu" by Feby Putri using Ferdinand de Saussure's semiotic approach. The purpose of the study is to reveal the relationship between the signifier and the signified in the song lyrics to understand the emotional and cultural messages contained therein. The method used is descriptive qualitative analysis with a focus on linguistic signs in the lyric text. The results of the study show that the song "Halu" utilizes metaphors (such as "candu" and "bayang-bayang") to represent one-sided love, illusion, and emotional alienation. The lyrics of the song are not only a personal expression of the creator, but also reflect the collective experience of the younger generation in interpreting unrealized relationships. This study concludes that popular music, through its semiotic structure, functions as a complex medium of cultural communication. Suggestions for further research include exploring the interaction of musical elements with lyrics and the application of other semiotic theories to enrich the analysis. These findings also emphasize the importance of media literacy in understanding music not only as entertainment, but also as a cultural product that is full of meaning.

The large number of cattle breeders in Indonesia has positive and negative values. Cattle farmers generally produce livestock waste such as cow rumen. Cow rumen can be used as a starter for alternative biogas energy production, and cabbage vegetable waste has the potential to be used as raw material for making biogas, because it contains nutrients such as crude protein (PK) 22.47%, crude fat (LK) 3.05%, crude fiber (SK) 12.09%, dry matter 10.22% and extract material without nitrogen 34.96%. Apart from that, in this research cow rumen and EM4 were also used as starters for the anaerobic fermentation process. The cow's rumen contains methane bacteria, namely Methanosarcina sp, and the cow's rumen also contains quite high levels of organic compounds with a COD value of 17,183 mg/l. Effective Microorganisms (EM4) are bacteria whose function is to accelerate the degradation process of organic materials. The aim of this research is to design a biodigester, and carry out biodigester design trials. The research methods carried out are COD analysis, CH4 analysis and pH analysis. The results showed that the percentage of CH4 increased in a mixture of 100% cow rumen, because the total COD value in the substrate was directly proportional to the addition of the cow rumen composition. This can be seen from the total COD in 100% beef rumen starter of 1175 ppm.

Noise generated by Diesel Power Plants (PLTD) is a significant environmental problem, especially in urban areas and settlements adjacent to power plant facilities. This study analyzes the noise level around the Fakfak Cotton Plant and its impact on the local community. This study uses a combination of methods, including noise level measurements using a Sound Level Meter (SLM), field observations, interviews with the community, and a SWOT analysis to evaluate the strengths, weaknesses, opportunities, and threats in noise mitigation. The measurement results show that the noise level generated exceeds the threshold of 55 dBA set by the Decree of the Minister of Environment Number 48 of 1996 for residential areas. This condition has a negative impact on the comfort, health, and social interaction of the community around the PLTD location, causing sleep disturbances, stress, and decreased quality of life. The SWOT analysis shows that although the PLTD has advantages in terms of sustainable operations and professional workers, the main weaknesses lie in the lack of soundproofing and the absence of regular noise evaluations. However, there is a great opportunity in the application of noise mitigation technologies, such as the installation of soundproofing, the use of acoustic walls, and planting vegetation as a sound barrier. In addition, collaboration with local governments and increasing environmental awareness can help manage noise impacts more effectively. The main threats identified include potential social conflicts with surrounding communities, negative health impacts, and changes in environmental policies that can affect PLTD operations. With the right mitigation strategies, such as the application of soundproofing technologies, improved communication with the community, and better integration of environmental policies, the environment around PLTDs can become more comfortable and conducive for the community. This study emphasizes the importance of regulatory and technology-based approaches in managing noise in urban environments, as well as the need for sustainable mitigation measures to maintain the well-being of communities around PLTDs..

Using smartphones in interpersonal communication among adolescents is now commonplace. Many teenagers who follow the flow of communication media in technology choose smartphones as a more effective interpersonal communication medium. Compared to other forms of communication, interpersonal communication occurs personally, in face-to-face situations, and through media. Interpersonal communication is fundamental since it permits it to require place dialogic communication. Exchange may be a shape of interpersonal communication that appears in the event of interaction. Those included in this communication frame are double-functioning, each being the speaker and the audience, on the other hand. This report analyzes adolescents’ interpersonal communication culture in the smartphone-use era based on this statement. The method used is the phenomenological method. The conclusion of this study indicates that the current adolescent interpersonal communication culture is more influenced by digital technology than direct interaction. Therefore, efforts are needed to foster awareness of the importance of maintaining a healthy quality of interpersonal communication amid technological advances.

Air quality in Western Java is highly dynamic and shaped by environmental changes influenced by intense human activities. Aerosols—tiny particulate matter that affects air quality, weather, and climate—can be quantified using Aerosol Optical Depth (AOD), which measures aerosol concentrations in the atmospheric column. This research uses spatial regression analysis to examine the spatial distribution of AOD from GEE’s platform (Google Earth Engine) and its relationship with rainfall and wind patterns during both the wet and dry seasons. The findings indicate that wind speed does not significantly impact AOD values, but wind direction does affect the distribution of rainfall and AOD, likely due to the monsoon system. During the wet season (December to March), high-intensity and widespread rainfall effectively cleanses the atmosphere of aerosols, leading to no significant effect on AOD (p-value > 0.05). In contrast, during the dry season, rainfall significantly influences AOD spatial patterns (p-value < 0.05). These results highlight the intricate interplay between meteorological factors and aerosol’s behavior, emphasizing the seasonal variability in their interactions.
