Manggis merupakan buah yang banyak ditemukan di daerah tropis, dan sudah lama buah ini menjadi pilihan untuk dikonsumsi, beberapa penelitian menunjukkan bahwa buah ini memiliki banyak kandungan vitamin dan juga antioksidan yang bermanfaat bagi tubuh manusia.Pada studi eksperimen ini digunakan ekstrak kulit buah manggis serta bakteri Acinetobacter baumanii.Tujuannya untuk mengetahui ada tidaknya aktivitas antibakteri ekstrak kulit buah manggis untuk bakteritersebut. Metode: Metode yang digunakan untuk menguji aktivitas antibakteri adalah metode sumuran. Antibiotik serta ekstrak kulit buah manggis dipipetkan pada setiap sumuran dalam satu medium agar yang berbeda, dengan konsentrasi yang berbeda-beda. Kemudian diinkubasi pada suhu 37oC selama 24-72 jam. Zona hambat bakteri uji diukur dengan mengukur daerah yang bening di sekitar sumuran. Hasil: Melalui uji Kruskal Wallis didapatkan hasil nilai p= 0,000 yang membuktikan bahwa terdapat perbedaan yang bermakna pada data-data tersebut. Dari uji Mann Whitney diperoleh hasil perbandingan antara tetrasiklin dengan aquades dan ekstrak kulit buah manggis dalam berbagai pengenceran memiliki perbedaan bermakna dengan nilai p < 0,05. Simpulan: Dapat disimpulkan bahwa secara statistik ekstrak kulit buah manggis tidak memiliki aktivitas antibakteri. Data ini sesuai dengan hasil percobaan yang menunjukkan tidak terbentuknya zona hambat pada agar yang diberi ekstrak kulit buah manggis. ......Mangosteen is a fruit that is found in the tropics area, and has long been a choice of fruit for consumption, some studies have shown that this fruit has alot of vitamins and also antioxidants that are beneficial for human. In the experimental study of the use of mangosteen peel extract and Acinetobacter baumannii. The goal is to determine whether there is the antibacterial activity of mangosteen peel extracts for bacteria. Methods: The method used to test the antibacterial activity is a method of diffusion. Antibiotics and mangosteen peel extract included in any medium in a different order, with different concentrations. Then incubated at 37 ° C for 24-72 hours. Bacterial inhibition zone test is measured by measuring the clear areas around sinks. Results: Through the Kruskal Wallis test showed p=0.000 which proves that there are significant differences in the data. Mann Whitney test obtained from the comparison between tetracycline with distilled water and mangosteen peel extracts in differentdilutions havesignificant differences with p<0.05. Discussion: The conclution that mangosteen peel extract has no antibacterial activity. The data are consistent with the results of experiments that showed no inhibition zone formation at a given order of mangosteen peel extracts.

Abstrak :
[Linear alkilbenzena sulfonat (LAS) adalah surfaktan dalam deterjen yang bersifat toksik terhadap organisme aquatik dan menurut Kepmenkes RI No. 492/MENKES/PER/IV/2010 kadar maksimum surfaktan dalam air adalah sebesar 0,5 mg/L. Degradasi LAS dilakukan dengan adsorpsi yang disimultan dengan peranan biofilm dari bakteri Acinetobacter baumanii yang terbentuk di atas permukaan karbon aktif jerami. Acinetobacter baumanii terbukti dapat membentuk biofilm diatas karbon aktif jerami dalam nutrient broth (NB), hal ini dibuktikan dengan adanya EPS (Extracellular Polymer Substance) pada Uji SEM dan FTIR. Analisis penurunan konsentrasi LAS dilakukan dengan menggunakan teknik MBAS (methylene blue active substance). Pada penelitian ini dilakukan degradasi LAS dengan dua variasi yaitu pertama variasi konsentrasi LAS 10 ppm, 20 ppm dan 30 ppm serta kedua variasi massa karbon aktif jerami yaitu 60 g, 100 g dan 150 mg. Hasil percobaan menunjukkan bahwa degradasi dengan konsentrasi 20 ppm pada massa karbon 150 gram memberikan hasil persen degradasi yang lebih besar, mencapai 96% pada hari ke-4 diikuti oleh degradasi LAS dengan konsentrasi 10 ppm yang mencapai 95% dan terkahir konsentrasi 30 ppm mencapai 56,25%. ;Linear Alkylbenzene Sulfonates (LAS) one of a kind surfactants in detergents and which is toxic to aquatic organisms, and according to Kepmenkes RI No. 492/MENKES/PER/IV/2010 the maximum levels of surfactant in water are 0.5 mg/L. LAS degradation conducted by adsorption simultaneously with the role of bacteria Acinetobacter baumannii biofilms formed on the surface of activated carbons straw. Acinetobacter baumannii shown to form biofilms on activated carbon straw in nutrient broth (NB), proven by the EPS (Extracellular Polymer Substance) presence in SEM and FTIR test. Degradation Analysis of LAS concentration was conducted by MBAS (Methylene Blue Active Substance). This research conducted with two variations: first variation is LAS concentration there are 10 ppm, 20 ppm and 30 ppm, and a second variation of the mass of activated carbon straw which are 60 g, 100 g and 150 g. The results showed that the LAS degradation with concentration 20 ppm at 150 grams have percentage degradation higher, reached 96% on day 4 followed by 95% for 10 ppm and the last 30 ppm, that is 56,25%. ;Linear Alkylbenzene Sulfonates (LAS) one of a kind surfactants in detergents and which is toxic to aquatic organisms, and according to Kepmenkes RI No. 492/MENKES/PER/IV/2010 the maximum levels of surfactant in water are 0.5 mg/L.
