Abstract

Present of lead as a heavy metal can be harmful to health. One possible method to reduce the presence of lead metal content is obtained through the adsorption process using adsorbent from rambutan rind. This study aimed to determine the effectiveness of activated charcoal from rambutan rind in absorbing lead metal with variations of difference adsorbent mass and stirring time. In this study, chemical activation was carried out by soaking the rambutan rind using 0.1 M NaOH solution for 24 hours. Adsorbents were characterized using Scanning Electron Miscroscopy (SEM) to determine the surface structure and particle size of the adsorbent. Furthermore, the adsorption process was carried out by contacting the adsorbent with lead solution based on the time difference of 10, 20 and 30 minutes and the adsorbent mass of 5, 10 and 15 grams. Based on the test results, the lowest concentration of lead was 1.692 and the highest concentration was 2.983. The most effective absorption of lead was at a level of 15 grams with a stirring time of 30 minutes with an absorption effectiveness of 83.30%.

Abstract

Tahu merupakan salah satu makanan favorit Indonesia karena mudah diperoleh dan rasa yang enak. Sebagian industri tahu Indonesia adalah industri rumah tangga sehingga sisa produksi yang dihasilkan dibuang langsung ke badan air. Limbah ini mengandung polutan yang menyebabkan bau tidak sedap dan nutrient yang dapat menyebabkan eutrofikasi. Oleh karena itu, diperlukan metode pengolahan limbah cair tahu yang tepat untuk menurunkan polutan hingga sesuai dengan baku mutu yang dikeluarkan oleh pemerintah. Pada penelitian ini, metode pengolahan limbah yang digunakan adalah metode fitoremediasi menggunakan tumbuhan enceng gondok dan mengkombinasikannya dengan proses koagulasi – flokulasi menggunakan bio koagulan Moringa Oleifera. Proses fitoremediasi dilakukan pada lingkungan yang terkontrol selama 21 hari, diikuti dengan proses koagulasi flokulasi untuk mengurangi kadar polutan agar sesuai baku mutu. Proses fitoremediasi limbah cair tahu mampu menurunkan COD dari 4000 mg/L menjadi 60 mg/L, BOD dari 1544 mg/L menjadi 20 mg/L, TSS dari 775 mg/L menjadi 150 mg/L, pH dari 4,3 menjadi 8,4. Kombinasi fitoremediasi dan koagulasi-flokulasi mampu menurunkan turbiditas dari 401 NTU menjadi 10 NTU. Rangkaian proses fitoremediasi dan koagulasi–flokulasi pada penelitian ini mampu menurunkan kadar polutan pada limbah cair tahu hingga sesuai dengan baku mutu yang dikeluarkan pemerintah.

Abstract

Oil waste that enters the soil will cause damage to the soil. Bioremediation is an alternative to hazardous waste treatment which is relatively more economical, easy and environmentally friendly. This technology utilizes microbial activity to treat polluted soil. Cow dung is an organic material that contains many microbes and also contains good nutrition for microbial growth. Cow dung contains several microorganisms such as bacteria (Bacillus sp, Lactobacillus sp and Corynebacterium sp), fungi (Trichoderma sp and Aspergillus sp), protozoan and yeast species (Candida sp and Saccharomyces sp). Cow dung in this study acts as a bioactivator and a source of nutrients for microbes in degrading Total Petroleum Hydrocarbon (TPH) in oil-contaminated soil. This study aims to determine the effect of adding cow dung on bioremediation of oil-contaminated soil. This study consisted of six (6) treatments, namely the concentration of cow dung with variations in concentrations of 0 gr, 20 gr, 40 gr, 60 gr, 80 gr, and 100 gr on each soil of 300 gr and processing time for 30 days and analyzed 2 times a day. In this study, measurements of pH and TPH values ​​were carried out. The results of the analysis showed that the addition of cow dung with a concentration of 100 gr on 300 gr of soil was able to reduce the TPH value from 3.6% to 0.2%, with the effectiveness of reducing TPH by 86.66% within 30 days. Based on the results of the analysis using the Simple Linear Regression Test, it was stated that the bioremediation time and the addition of the concentration of cow dung had an effect on the decrease in the TPH value.

Abstract

Flight activities at the airport such as takeoffs and landings can cause noise. It can disturb the people who live around the airport. The people who are affected by the aircraft noise over a long period of time will experience health problems. This study aims to determine whether the settlement area around the Sultan Iskandar Muda International Airport is included in the noise area that has been defined. The noise distribution was analyzed using the software Integrated Noise Model. In this study, the noise simulation uses flight data which has been classified for one week based on the flight path used. The result of this study showed that there was one school building in the noise area level I and the settlement in the noise area level II. Further research is needed for seeing the aircraft noise at its peak conditions when the airport is in normal situation, and the aircraft noise mitigation could be done to reduce the impact of aircraft noise.
