One of the environmental issues that arises is noise pollution, especially in urban areas experiencing high growth in the transportation sector. The research aims to evaluate the relationship between road service levels and noise levels. The analysis of the data reveals that the highest peak hour volume occurs on Mondays from 12:00 to 12:15, with a value of 133.8 vehicles per hour (vph), followed by Sundays from 16:00 to 16:15 with 130.7 vph. The road capacity reaches 1484.05 vph with a Volume-to-Capacity Ratio (DS) of 0.101 (DS < 0.75), indicating good service levels. The free-flow speed of vehicles on Imam Bonjol street is 34.06 km/h. Overall, the road is categorized at service level B. However, the noise level generated by vehicles around this road is quite high, exceeding the established quality standards ranging from 58 to 63 dB. The highest values occur on weekdays, especially during peak hours, indicating that traffic volume and surrounding activities influence noise levels. Noise exceeding the standard limits can have negative impacts on human health and environmental comfort.","PeriodicalId":516595,"journal":{"name":"Lingkar: Journal of Environmental Engineering","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140502131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This mosque is used for worship, this mosque is often utilized for major religious activities. The Grand Mosque of Al-Falah has a rich history. It was constructed in the 18th century by Sultan Thaha Syaifuddin, a leader of the Jambi Sultanate at that time. As a result, this mosque has become one of the significant historical heritages in the city of Jambi. This study aims to examine the implementation of sanitation standards for public places in the Agung Al-Falah Mosque tour in Jambi City. The research employs a mixed-method approach, which combines qualitative and quantitative methods. The assessment is conducted using a checklist and interview instruments, and the collected data are presented. Based on the research findings, it is evident that the assessment of Environmental Aspects (both outside the yard and inside the structure) achieved a percentage of 97.5%, while Sanitation Facilities (Clean Water, Wastewater, Garbage, and Bathrooms) attained a percentage value of 100%. The total score for all sanitation variables used amounted to 98.5%. So, the sanitation implemented in the religious tourism site of the Agung Al-Falah Mosque in Jambi City is deemed healthy, as the total variable score surpasses 75%.","PeriodicalId":516595,"journal":{"name":"Lingkar: Journal of Environmental Engineering","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140502341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pemrosesan limbah cair yang efektif dan efisien sangat penting untuk menjaga keberlanjutan lingkungan. Penelitian ini bertujuan untuk menganalisis penggunaan media filtrasi multi layer dalam pemrosesan limbah cair. Media filtrasi multi layer terdiri dari beberapa lapisan dengan sifat dan ukuran pori yang berbeda. Setiap lapisan memiliki peran tertentu dalam menghilangkan partikel dan kontaminan dari limbah cair. Dalam analisis ini, kami mengumpulkan data tentang performa media filtrasi multi layer dalam menghilangkan zat pencemar tertentu, seperti pH, COD, TSS, dan kekeruhan. Metode yang digunakan dalam penelitian ini meliputi pengambilan sampel limbah cair dari SPBU kuta alam, pembuatan media filtrasi multi layer dengan kombinasi lapisan yang tepat dan pengujian performa media filtrasi menggunakan teknik analisis laboratorium yang sesuai. Kesimpulan penggunaan media filtrasi multi layer dapat menjadi solusi yang efektif dalam pemrosesan limbah cair. performa filtrasi yang tinggi dan mampu menghilangkan berbagai zat pencemar.

The data noise collection method uses a Sound Level Meter (SLM) with the HT-80A type and also counts the number of two-wheeled and four-wheeled vehicles passing by using the Traffic Counter application that has been installed in a smartphone. Noise can have an impact on human health, especially hearing problems and also cause inconvenience to both road users and residents in the vicinity. The variables that will be discussed are: volume of vehicles, especially two-wheeled and four-wheeled vehicles, and noise intensity. This data collection is needed to find the noise level and then compared using the standard allowable level, namely using the Decree of the State. Minister for the Environment No: Kepmen-48/MENLH/11/1996 for residential zones. Data analysis uses the Leq formula and then also uses the chi-square method to determine the relationship between the two variables. The total number of vehicles passing on the Taman Siswa road during the measurement was 23,530. In this study, the significance level used was 0.05 with the result that the p value for two-wheeled vehicles was 0.008 and for four-wheeled vehicles was 0.2.
