Abstract

This research is intended to analyze the quality of tofu liquid waste, analyze the quality of river water around the tofu industry in Mejing Village and analyze government policies in managing tofu liquid waste. The research method used is grab sampling, observation, and interviews to obtain primary data. Secondary data from journal articles and research reports are used to support primary data. The research results show that the quality of tofu liquid waste has a pH of 2.8-33, a temperature of 41-51 oC and is not in accordance with established quality standards. Tofu liquid waste also has a pungent sour odor, yellowish color, and contains many suspended particles. Disposal of tofu liquid waste into the waters causes the river flowing in Mejing Village to be dirty and indicates light to heavy pollution. The government has set quality standards for wastewater produced by the tofu industry. Unfortunately, the tofu industry in Mejing Village does not comply with this regulation properly. The low awareness of tofu industry players to manage liquid waste is caused by various factors. Good communication between the government and industry players is needed so that industry players know how to process the liquid waste they produce. The government needs to supervise the application of government regulations related to the management of tofu liquid waste and provide sanctions to industries that violate it. Planning for a communal IPAL as well as an appropriate solution must be realized immediately so that the problem of tofu liquid waste in the tofu industry center in Mejing Village can be resolved immediately.

Abstract

Forests are natural ecosystems that consist of large areas of land that contain many biological resources. Forest fires have several factors, namely due to human activity, high air temperatures. In this study, the cause of forest fires on Mount Sumbing is due to very hot air temperatures, the temperature this year is hotter than the average, this is due to the phenomenon of hot air trapped in the area due to anomalous atmospheric dynamics. The purpose of this study is to determine the potential for summer to cause forest fires on Sumbing Mountain. The research method used is qualitative descriptive analysis based on the results of drought index management related to the distribution of hot spots in 2023. The results of the research studied by the researcher are the fires that occurred in the Mount Sumbing forest on Friday, 1 which resulted from hot weather. So the potential for forest fires that occur on Mount Sumbing during hot weather has a very large potential and causes serious forest fires, therefore the guards on Mount Sumbing are dexterous if unwanted things happen such as evacuating residents and climbers

Abstract

Penambangan pasir di Kawasan Gunung Merapi Kabupaten Sleman, Yogyakarta telah menyebabkan kerusakan ekosistem yang signifikan. Tujuan dari penelitian ini adalah untuk mengidentifikasi dampak kerusakan ekosistem akibat penambangan pasir di kawasan tersebut. Metode penelitian yang digunakan adalah pendekatan yang mengintegrasikan studi literatur dan analisis data sekunder. Hasil penelitian menunjukkan bahwa penambangan pasir secara berkala menyebabkan berkurangnya keanekaragaman hayati baik flora maupun fauna. Selain itu, kondisi topografi di kawasan Gunung Merapi juga mengalami perubahan akibat pengerukan pada wilayah-wilayah sungai yang dapat menyebabkan tanah longsor pada tebing, erosi sungai, dan terjadi perubahan pola aliran sungai. Penambangan pasir yang dilakukan secara ilegal dan tanpa izin semakin memperparah kerusakan ekosistem di kawasan tersebut. Oleh karena itu, pengelolaan keanekaragaman hayati menjadi jalan utama agar tercipta keanekaragaman yang stabil, aman, dan berkelanjutan.

Abstract

The Dieng Plateau is an area with an abundant diversity of flora and fauna. However, this area can experience temperatures. The objectives of this research are 1) to determine the factors causing drastic temperature changes in the Dieng area, Central Java; 2) to analyze the impact of temperature changes on the environment, ecosystem, and living creatures in Dieng; and 3) to look for solutions to overcome the negative impacts of changes in Dieng. The research method used is a study of literature  from several journals which is then summarized, analyzed, and supported by the researcher's arguments. The Dieng area has different temperatures during the day and at night, making it different. This impacts the agricultural, tourism, health, quality, and availability of drinking water sectors. This can be overcome with several strategies, such as using plants resistant to temperature changes, maintaining body health, and good tourism management. Therefore, significant temperature changes have positive and negative impacts on the ecosystem and surrounding communities.

Abstract

Environmental issues caused by plastic waste have become both an ecological and humanitarian crisis. In response to this reality, this study aimed to explore how the song Plastic Tree by Endah N Rhesa serves as an agent of ecological critique through poetic symbolism. Using Ferdinand de Saussure’s semiotic approach, the song lyrics were analysed as signs conveying hidden environmental meanings. Symbols such as “plastic tree,” “rubber bee,” and “paper bird” reflect the loss of natural ecosystems replaced by lifeless artificial objects. The analysis revealed that the song successfully builds ecological awareness and rejects superficial solutions, thereby encouraging listeners to become more reflective and concerned about their surrounding environment.
