Abstract

 ABSTRACTThe manufacture of a biodegradable plastics film containing of polymer synthetic polystyrene(PS) and biopolymer of polycaprolactone (PCL), poly(3-hydroxybutyrate-co-3-hydroxyvalerate)[P(3HB-ko-3HV)] and biodegradation study in ocean water has been carried out. Plastics filmcontaining of PS/PCL/P(3HB-ko-3HV) produced by blending techniques followed by solventcasting with ratios were of 100/0/0, 95/5/0, 95/0/5, 90/5/5, 85/10/5, 85/5/10. This testing wasconducted based on immersion test method recommend by American Society for Testing andMaterials. Poly blend plastics film PS/PCL/P(3HB-ko-3HV) were characterized by tensilestrength, thermal properties and SEM analysis. The profiles of the rate biodegradation view byweight reduction of the tested plastic film for 1-7 weeks period. Tensile strength analysisshowed the decreasing of tensile strength with the addition of P(3HB-ko-3HV). Thermalanalysis showed a decreasing in the melting point with the addition of PCL and P(3HB-co-3HV). SEM micrograph showed the destruction occurred and erosion at surface of plastic filmduring observation time. The rate of biodegradation showed that increasing of PCL and P (3HBco-3HV) in a mixture of plastic film, so biodegradation increased.Keywords: polystyrene, polycaprolactone, poly(3-hidroxybutyrate-co-3-hydroxyvalerate),biodegradation, film plastic.

Abstract

One of the plants that can be used as traditional medicine is mahogany (Sweitenia mahagoni). The presence of flavonoid compounds in mahogany seeds is suspected as a compound that serves to inhibit bacterial growth. One of the antibacterial effects is to treat diarrhea diseases caused by Shigella dysenteriae. Diarrhea is infectious intestinal disease a public health problem in developing countries. The aim of this research is to know and measure the inhibition zone of ethanol extract of mahogany seed to the growth of Shigella dysenteriae bacteria with concentration 25%, 50%, 75%, 100%. This research is a descriptive study in vitro using disc method. The result of the research has found that the average inhibition zone diameter at 25%, 50%, 75%, 100% concentration is 6mm, 8mm, 8.33mm, 10.33mm. Negative controls do not provide inhibition and positive control yields an average diameter of 21.33 mm. Based on the above results, it can be concluded mahogany seed extract provides resistance to Shigella dysenteriae.

Abstract

Escherichia coli merupakan flora normal di dalam usus manusia dan akan menimbulkan penyakit bila masuk ke dalam organ atau jaringan lain. Salah satu penyebab manusia terinfeksi oleh Escherichia coli adalah berasal dari makanan atau minuman yang terkontaminasi bakteri Escherichia coli dengan gejala berupa diare yang di sertai darah, kejang perut, dan demam. Tujuan penelitian ini adalah untuk mengetahui cemaran bakteri Escherichia coli pada 3 depot air minum isi ulang yang dijual di jalan Pemuda Kelurahan Tampan Kecamatan Payung Sekaki Pekanbaru. Motode yang digunakan adalah metoda kultur atau pembiakan bakteri pada media pengkayaan di lanjutkan dengan media selektif. Selanjutnya hasil positif dilanjutkan dengan uji penagasan menggunakan reaksi biokimia. Berdasarkan hasil penelitian, pada sampel A, B dan C menunjukkan adanya bakteri gram negatif, namun pada reaksi biokimia bukan menunjukkan ciri-ciri bakteri Escherichia coli. Dengan demikian 3 jenis air minum isi ulang di jalan Pemuda Kelurahan Tampan Kecamatan Payung Sekaki Pekanbaru tidak terkontaminasi oleh  bakteri Escherichia coli.

Abstract

The use of celery leaves in this study is because celery leaves contain antibacterial compounds such as saponins, tannins, and flavonoids. The aim of this study was to determine the antibacterial activity of the ethanol extract of celery leaves against Staphylococcus Aureus at concentrations of 10%, 30%, and 50% using the agar diffusion method, with chloramphenicol as a positive control and Aquadest as a negative control. The extraction method was carried out by maceration method using 96% ethanol solvent. Inhibition test results with concentrations of 10%, 30%, and 50% of celery leaf ethanol extract could inhibit the growth of Staphylococcus Aureus with an average diameter of the inhibition zone of 0 mm, 0.6 mm, and 10.6 mm. From the above results, the ethanol extract of celery leaves has antibacterial activity with weak activity against Staphylococcus Aureus.

Abstract

Tanaman alpukat (Persea americana Mill) merupakan tanaman yang dapat tumbuh subur didaerah tropis seperti Indonesia dan merupakan salah satu jenis buah yang digemari oleh masyarakat karena rasanya yang enak. Penggunaan daging buah alpukat pada penelitian ini dikarenakan daging buah alpukat memiliki kandungan senyawa antibakteri seperti saponin, tanin, alkaloid, flavanoid, steroid, dan fenol. Tujuan penelitian ini adalah untuk mengetahui aktivitas antibakteri daging buah alpukat dan ekstrak etanol daging buah alpukat terhadap Escherichia coli pada konsentrasi 30%, 50%, dan 70% menggunakan metode difusi agar, siprofloksasin sebagai kontrol positif dan DMSO sebagai kontrol negatif. Metode ekstraksi dilakukan dengan metode maserasi menggunakan pelarut etanol 96%, buah alpukat yang berwarna hijau. Hasil uji daya hambat dengan konsentrasi ekstrak etanol daging buah alpukat 30%, 50%, dan 70% dapat menghambat pertumbuhan Escherichia coli dengan rata-rata diameter zona hambat 11,45 mm, 12,42 mm, dan 13,95 mm, dan kontrol positif siprofloksasin adalah 25,94 mm. Zona hambat rata-rata pada daging buah alpukat 8,9 mm, 7,73 mm, dan 6,66 mm pada konsentrasi 30%, 50%, dan 70% dan kontrol positif siprofloksasin adalah 28,56 mm. Dari hasil diatas dapat diambil kesimpulan bahwa daging buah alpukat dan ekstrak etanol daging buah alpukat (Persea americana Mill) memiliki aktivitas antibakteri terhadap Escherichia coli.

Abstract

Phlebotomy technique (Fasdhu) is a technique used to remove blood from the functioning cubital vein. This technique is useful for reducing excess levels in the body, one of which is high blood pressure (hypertension). Many methods have been used to reduce high blood pressure, including synthetic drugs, consuming herbal medicines and several other efforts that are thought to be able to reduce blood pressure. The aim of this service is to hope that hypertension sufferers will return to normal blood pressure after carrying out the phlebotomy (fasdhu) technique. The method or implementation stages used in this service begin with providing education about hypertension, followed by the next stage of measuring blood pressure, the next stage of removing blood using the phlebotomy technique (fasdhu) and the final stage of measuring blood pressure after treatment with the phlebotomy technique. From the treatment carried out on 10 respondents who experienced high blood pressure, the average blood pressure before the phlebotomy technique (fasdhu) treatment was 172/88.5 mmHg, while after the treatment the average blood pressure was 148.2/88.3 mmHg. From the results of the phlebotomy technique (fasdhu) treatment that has been carried out, the fasdhu technique treatment is able to reduce high blood pressure. Key words: Phlebotomy, fasdhu, hypertension.

Abstract

Bakteri Mesofilik merupakan bakteri yang dapat tumbuh pada suhu 25-40ºC. Beberapa jenis bakteri Mesofilik diantaranya E.coli, Salmonella thypi, dan Shigella dysenteriae. Jenis bakteri ini dapat menimbulkan berbagai macam penyakit yang menginfeksi pada saluran pencernaan manusia seperti diare, sakit perut, muntah, dan penyakit saluran pencernaan lainnya. Bakteri jenis ini banyak dijumpai pada air mentah atau makanan yang kurang matang. Tujuan dari penelitian ini adalah untuk mengetahui ada atau tidaknya cemaran bakteri patogen mesofilik pada dua sumber air bersih yang berada di Jalan Riau Ujung kota Pekanbaru. Metoda yang digunakan adalah metoda kultur atau pembiakan bakteri pada media pengkayaan, dilanjutkan dengan pewarnaan gram, penanaman pada media selektif dan uji penegasan yaitu uji reaksi biokimia. Hasil penelitian menunjukkan bahwa pada sampel sumber air A yang berada di Kelurahan Air Hitam tidak ditemukan bakteri mesofilik. Sedangkan pada sampel sumber air B yang berada di Gg.Anggrek ditemukan adanya bakteri mesofilik Escherichia coli dan Enterobacteraerogenes.
