Abstract

Natural medicine is safer than modern or synthetic medicine because it has few side effects if used correctly. The aim of this research is an introduction test to know the barrier power of sarang tawon angkut-angkut extracts (Eumennes coarcatus) as a natural antimicrobial for avoiding Escherichia coli growth. Kirby bauer method (paper disk method) is used in this research. Sarang tawon angkut-angkut extract is used for the sample and 0.5 mL Escherichia coli bacterial suspension. The result of this research showed that sarang tawon angkut-angkut extract has barrier power as naturally antimicrobial in Escherichia coli growth with 4.2 mm average of barrier zone with weak antibacterial activity. This research concludes that sarang tawon angkut-angkut extract has potency as an antimicrobial. ABSTRAKPenggunaan obat alami dinilai lebih aman dari pada obat modern atau sintetis karena memiliki efek samping yang relatif kecil jika digunakan secara tepat. Penelitian ini bertujuan untuk uji pendahuluan mengetahui adanya daya hambat ekstrak sarang tawon angkut-angkut (Eumennes coarcatus) sebagai antimikroba alami untuk mencegah pertumbuhan bakteri Escherichia coli. Metode yang digunakan adalah metode Kirby bauer (metode kertas cakram). Sampel yang digunakan adalah ekstrak sarang tawon angkut-angkut dan suspense bakteri 0,5 mL bakteri Escherichia coli. Hasil penelitian menunjukkan bahwa ekstrak sarang tawon angkut-angkut memiliki daya hambat sebagai antimikroba alami dalam pertumbuhan Escherichia coli dengan rata-rata diameter zona hambat yaitu 4,2 mm dengan aktivitas antibakteri lemah. Kesimpulan penelitian ini adalah ekstrak sarang tawon angkut-angkut memiliki potensi sebagai senyawa antimikroba.

Abstract

The electrokinetic remediation method can function as a primary or secondary technology and can be applied in conjunction with other physical and biological methods, such as soil washing, phytoremediation, and bioremediation. Environmental impacts arising from the electrokinetic remediation process can be determined using life cycle assessment analysis (LCA) or other tools. This study compared the conventional electrokinetic remediation strategy with two hybrid strategies: electrokinetic-phytoremediation (EKR-Phyto) and electrokinetic-bioremediation (EKR-Bio). The environmental performance of the three strategies is then tested through LCA analysis. The database used was The Ecoinvent, and the freeware software used during the inventory stage was OpenLCA. The impact assessment stage was used in the Recipe I (2016) midpoints, Available Water Remaining (AWARE) midpoint, Intergovernmental Panel Climate Change (IPCC) midpoint (2003), UNEP Society of Environmental Toxicology (USEtox) midpoint, and cumulative energy demand midpoint. The significance of the analysis results was not obtained for the GWP parameter but for the freshwater eutrophication parameter. Among the three strategies, the EKR-Phyto strategy showed the highest significance in eutrophication but the lowest significance in land change. Substitution of chemical fertilizers into natural fertilizers in the EKR-Phyto strategy can be an opportunity for environmental sustainability. The highest impact for ecological analysis of the three strategies was EKR-Phyto in terms of GWP, the sum of primary energy, Acidification Potential (AP), and Photochemical Ozone Creation Potential (POCP).

Abstract

The Content of fat and oil in laundry wastewater can cause environmental problems. This study aims to determine the effect of giving EM4 in the preliminary test of simple filtration bioventing techniques on the treatment of laundry wastewater. The initial work step is to design a bioventing using an aerator and sand media, while simple filtration using gravel, coconut fiber, durian skin, zeolite stone and foam filter media. The research was conducted with two treatments in the bioventing tub, the first treatment of 2000 ml of laundry wastewater added 15 ml of EM4 and the second treatment of 2000 ml of laundry wastewater without adding EM4. On the sixth day, two treatments were added with Pistia stratiotes plants as phytoremediation and molly balloon fish as an indicator. Testing of pH, temperature, DO, color and odor parameters was carried out in the inlet and outlet basins. The results of the research on the provision of EM4 in the laundry wastewater treatment process have a significant effect on reducing the pH parameter value, very significantly reducing the temperature value and significantly increasing the DO value. The color parameter shows a change solid white to digestible white, while the odor parameter shows data from pungent to not pungent. Observation of molly balloon showed no dead fish. This study concludes that there is an effect of giving EM4 to the parameters values of pH, Temperature, DO, Color, and Odor in the preliminary test of simple filtration bioventing techniques and phytoremediation of laundry wastewater treatment. ABSTRAK Kandungan lemak dan minyak yang terdapat di air limbah penatu dapat menimbulkan gangguan lingkungan. Penelitian bertujuan mengetahui pengaruh pemberian EM4 pada uji pendahuluan teknik bioventing filtrasi sederhana terhadap pengolahan air limbah penatu. Langkah kerja awal membuat desain alat bioventing menggunakan media aerator dan pasir, alat filtrasi sederhana menggunakan media batu kerikil, serabut kelapa, kulit durian, batu zeolit dan busa filter. Penelitian dilakukan dua perlakuan tiga ulangan. Perlakuan kesatu 2000 ml air limbah penatu ditambahkan EM4 sebanyak 15 ml dan perlakuan kedua 2000 ml air limbah penatu tanpa ditambahkan EM4. Hari ke enam, kedua perlakuan tersebut ditambahkan tumbuhan Pistia stratiotes sebagai fitoremediasi dan ikan molly balon sebagai bioindikator. Pengujian parameter pH, Suhu, DO, warnadan bau dilakukan di bak inlet dan bak outlet. Hasil penelitian pemberian EM4 pada proses pengolahan air limbah penatu berpengaruh signifikan untuk menurunkan nilai parameter pH, sangat signifikan menurunkan nilai parameter suhu dan signifikan menaikkan nilai parameter DO. Parameter warna menunjukkan perubahan putih pekat menjadi putih jernih sedangkan parameter bau menunjukkan bau menyengat menjadi tidak menyengat. Pengamatan Ikan molly balon menunjukkan tidak ada ikan yang mati. Kesimpulan penelitian ada pengaruh pemberian EM4 terhadap perubahan nilai parameter pH, Suhu, DO, perubahan Warna, perubahan Bau pada uji pendahuluan teknik bioventing filtrasi sederhana terhadap pengolahan air limbah penatu.
