Limbah cair tahu dapat dimanfaatkan, salah satunya adalah bahan bakar biogas yang tentunya berguna bagi masyarakat. Selain limbah tahu, limbah roti juga dapat digunakan sebagai bahan untuk pembuatan biogas. Limbah cair tahu dan limbah roti memiliki semua komponen yang dapat dijadikan sebagai feedstock untuk proses biogas yang menjanjikan karena limbah roti dan limbah cair tahu mudah didapatkan. Penelitian ini bertujuan untuk mengetahui hasil dari kombinasi limbah cair tahu, limbah roti dan feses sapi yang sudah kadaluarsa serta untuk mengetahui zat apa saja yang dihasilkan oleh kombinasi limbah cair tahu, limbah roti dan feses sapi yang sudah kadaluarsa. Pengamatan pada suhu di dalam biodigester dilakukan selama 42 hari, dan hasil dari pengamatan didapatkan suhu rata-rata pada digester 1= 31,4, pada digester 2= 31,2, dan pada digester 3= 31,2. Proses produksi gas berada pada rentang suhu diatas 30oC yang merupakan rentang suhu yang optimal untuk produksi biogas.

Kegiatan di sekitar jalan raya tidaklah lepas dari kehadiran alat transportasi seperti kendaraan bermotor. Kepemilikan dari kendaraan bermotor semakin meningkat setiap harinya baik itu milik pribadi ataupun kendaraan umum sehingga menimbulkan kebisingan pada daerah tersebut. Kebisingan merupakan suatu bunyi atau suara yang tidak diharapkan dari suatu usaha maupun suatu aktivitas dengan rentang waktu pemaparan yang tertentu sehingga dapat menyebabkan berbagai gangguan pada kesehatan tubuh manusia serta terganggunya kenyamanan akan lingkungan hidup. Oleh karena itu kebisingan perlu direduksi atau dimitigasi dampaknya. Salah satu Metode yang dapat digunakan untuk mengurangi tingkat kebisingan yaitu menggunakan Metode MEAD. Metode ini berkaitan dengan menganalisis, mengevaluasi dan mendesain sistem kerja dalam organisasi sehingga dapat menjadi lebih efektif serta efisien. Dari hasil penelitian di SPBU Lingke Banda Aceh didapati bahwa persebaran tingkat intensitas kebisingan yang diuji pada titik 1 hingga 7 diperoleh dengan rata-rata masih dibawah 85 dBA.

One of the reclamation stages is re-vegetation to plant the exploited mine area with cover crops. Cover crop monitoring commonly is taken by direct assessment of plants growth. However, this approach is ineffective and also expensive which is proportional to the large reclamation area. The objective of this research is to apply remote sensing methods to monitor cover crop growth at Siltstone Quarry of PT Aroma Cipta Anugrahtama, in Lhoknga subdistrict, Aceh Besar. The monitoring was conducted using Sentinel-2 satellite imagery data by computing the Normalized Difference Vegetation Index (NDVI). The analysis was done in a time series from the year 2019 to 2022 using the Google Earth Engine (GEE) cloud platform. The result shows that the NDVI value is varied from 0 to 0,8 which is classified into no vegetation to high vegetation area. Based on spatial distribution of NDVI values, can be observed that the northern area has higher uniform NDVI value compared to the southern area which is more mixed. This indicates the southern part has been exploited earlier. Overall the re-vegetation successful rate for reclamation zone before 2019, 2019, 2020, 2021 and 2022 are 96%, 99,5%, 70,6%, 36,6% and 6,2%. \u0000 ","PeriodicalId":223573,"journal":{"name":"Lingkar : Journal of Environmental Engineering","volume":"318 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121745600","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}

One method of treating vehicle washing liquid waste using a filtration system has been proven to be effective and capable of breaking down pollutants contained in wastewater. However, filtration using activated carbon, silica sand, zeolite and gravel media with different variations and doses of media thickness to reduce levels in the parameters pH, TSS, COD and Phosphate has not been studied. This study was conducted to determine the effect of variations and doses of filter media and their effectiveness in reducing the levels of TSS, COD, pH and Phosphate in vehicle washing waste, with variations in the thickness of activated carbon media 10, 20, 25 cm and silica sand, zeolite, gravel 15 , 20 cm. The results showed that activated carbon, silica sand, zeolite and gravel media were able to reduce TSS, COD, pH and phosphate levels. The decrease in levels is highest in the 6th variation. The percentage of TSS is 97.13%, COD is 93.93%, Phosphate is 74% and a decrease in pH 7.

This study aims to test the quality of rainwater in the district of Syiah Kuala, Banda Aceh City, then plan the design of a rainwater harvesting system for shop houses that are often found in this area. The study conducted by testing the physical parameters of rainwater quality, collecting common shop house dimension data, and rainfall data, then calculating the potential rainwater that can be harvested by hydrology analysis, and then determine the volume, design, drawing of the rainwater harvesting system.
