Effect of Serving Factors of Milk Powder in Sachet Packaging on Total Microbial
The aim of this research was to study the microbial quality of milk powder based on the serving factors during milk powder serving process. The method used in this research was Total Plate Count (TPC). Nine sachets (400 g/sachet) of milk powder was used as many as This experiments used Split Plot Design, comprised three factors, storage factor (P1, P2 and P3), time of serving factor (morning and evening), and shelf life factor (day of 1st-7th). Each treatment consisted of three sachets of milk powder. Storage factors comprised P1 (sachets packaging contained of milk powder were placed into the glass bottle container), P2 (sachets packaging contained of milk powder were placed into glass botlle with spoon inside, and P3 (sachets packaging contained of milk powder with spoon inside were not placed into the glass bottle container). The results of this research showed that storage factors and time of serving did not sifnificantly (P>0,05) affect on the microbial count of milk powder, but shelf life factor significanly (P<0,01) affected on microbial count of milk powder at day of 1th and 7th. Milk powder in sachet packs (400 grams) has been opened, with or without spoon in the sachet and more than five days of shelf life can increase the total number of microbes, which was exceed TPC decision at 5x104 CFU/grams of milk powder
Optimum Feature for Palmprint Image Authentication
Palm print authentications have become extensive research in recent years. Some research discussing palm print authentication emphasize on matching of two feature vectors of it. Problem faced by the research in this field is the sampling process. Different position of hand geometry results in different palm print image cause palm print to be unauthenticated. This research proposes an approach to solve the problem by first making image dimension using Multi-scale Wavelet Pyramid (MWP) to produce features represent palm print image. The next stage is feature matching by using Hamming Distance Similarity. Testing in several levels combination show that integration of level 1 and level 2 yields optimum feature. The evaluation result produce that MWP has faster and better performance accuracy up to 77.93% with threshold 4700
Isolasi Dan Karakterisasi Aktinomisetes Penghasil Antibakteri Enteropatogen Escherichia Coli K1.1, Pseudomonas Pseudomallei 02 05, Dan Listeria Monocytogenes 5407
Isolation and Characterization of Actinomycetes ProducingAntibacterial Compound into EnteropatogenikEscherichia coli K1.1, Pseudomonas pseudomallei 02 05and Listeria monocytogenes 5407. Dwi N. Susilowati,Ratih D. Hastuti, and Erny Yuniarti. The resistance ofbacterial pathogens to some antibacterial agents and sideeffects of the antibacterial USAge demanded discovery ofnew effective, safe, and active antibacterial compounds.Some pathogenic bacteria, such as enteropathogen Escherichiacoli (EPEC) that cause diarrhoea on children andinfants, Pseudomonas pseudomallei that cause melioidosison human and animal, and Listeria monocytogenes thatcause listeriosis on newly born babies mortality and death ofpregnant woman. Actinomycetes is the largest bacterialgroup that produce antibiotics. More than 10,000 antibacterialcompounds had been discovered, two-third ofthem were produced by this bacterial group. A study wasdone to isolate and characterize Actinomycetes producingantibacterial compounds effective against EPEC K1.1 and P.pseudomallei 02 05. Soil samples were taken from 39locations in Indonesia and 115 actinomycetes isolates wereobtained. Two of the isolates, i.e., isolate A3.5 that waseffective against P. pseudomallei 02 05 and isolate F6.1 thatwas effective against EPEC K1.1 evaluated further. Theisolate A3.5 had an optimum time 72 hours to produce antibacterialcompound, while F6.1 took 96 hours. The antibacterialcompounds produced by both isolates were dissolvein the a 70% ethyl acetate solution, but not in a 40oCwarm methanol solution because it is very dissolved. Theantibacterial compound extracted from the isolate A3.5 hada similar effectiveness to antibiotics bacithracyn 10 unit andneomycin 30 g. On the other hand, the antibacterialcompound extracted from isolate F6.1 had a similar effectivenessto antibiotics colistin 10 g and doxyciclin 30 g.Further identification of the isolates suggested that both ofthem belongs to the genera Streptomyces
Increasing of N-uptake by Inoculation of Diazotroph Endophytic Bacteria in Vermiculite Media
Intensive selection of selected 15 isolates on N2-fixing activities and auxin production to diazotroph endophytic bacteria showed that five isolates were superior, that is KACP12 (0.2569 μmol hour-1 culture-1), KACP13 (0.3026 μmol hour-1 culture-1), KACP21 (0.4592 μmol hour-1 culture-1), KACP32 (0.3131 μmol hour-1 culture-1), and KAMG2 (0.4843 μmol hour-1 culture-1). Inoculated five superior isolates into soybean seeds in vermiculite media showed that soybean plant inoculated by KAMG2 has the highest nitrogenase specific activity compared to others and control, that is 2,54 ± 1,2 μmol hour-1 plant-1. However inoculation with KACM and KACP32 showed higher N-uptake of soybean plant. Although this research has conducted within theearly stage of soybean plant growth, it is obvious that inoculated diazotroph endophytic bacteria in vermiculite media seem to be a good method to introduce selected strain envisaging growth promoting and nitrogen fixation
Etika Kesehatan pada Persalinan melalui Sectio Caesarea tanpa Indikasi Medis
Angka persalinan dengan sectio caesarea di Indonesia terbilang cukup tinggi. WHO menyatakan, angka sectio caesarea maksimum sekitar 10 sampai 15%. Oleh karena itu, perlu dikaji pengambilan keputusan melakukan tindakan sectio caesarea berdasarkan prinsip-prinsip etika kesehatan. Penelitian ini menggunakan pendekatan kualitatif, yang dilaksanakan di rumah sakit dan klinik persalinan di Jakarta. Pengumpulan data melalui wawancara mendalam pada narasumber tenaga medis fungsional, bidan dan manajer rumah sakit. Data dianalisis menggunakan content analysis. Hasil penelitian menunjukkan trend persalinan sectio caesarea sangat tinggi mencapai 70%. Persalinan sectio caesarea hampir seluruhnya disebabkan indikasi medis. Trend persalinan melalui tindakan sectio caesarea yang sangat tinggi tidak serta merta menunjukkan bahwa terdapat hal yang bertentangan dengan etika pelayanan kesehatan. Banyak faktor di luar indikasi medis, baik dari sisi ibu maupun bayi, yang menyebabkan sectio caesarea dipilih,antara lain faktorpsikis ibu,peralatan medis yang tidak siap digunakan untuk persalinan normal, hak pasien dalam memilih tindakan medis yang ingin dilakukan, regulasi yang lemah dalam mengendalikan rumah sakit yang menawarkan paket sectio caesarea, serta regulasi yang dipandang merusak sistem jasa medis yang telah berjalan baik sehingga mendorong moral hazard dari para dokter untuk membiarkan adanya permintaan persalinan melalui sectio caesarea tanpa indikasi medis yang adekuat

Teknologi pengawetan kayu dengan metode infus dan bandage-wrapping pada pohon berdiri yang masih hidup merupakan metode baru dalam pengawetan kayu. Metode ini memiliki keunggulan dapat mengawetkan kayu berukuran besar secara mudah. Kayu utuh berukuran besar dibutuhkan untuk bahan baku pembuatan Jalur, yaitu, perahu tradisional khas daerah Riau. Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan pengawetan kayu pada pohon berdiri terhadap karakteristik kayu, terutama sifat kimia dan sifat mekanisnya. Masing-masing sebanyak dua pohon dari jenis kayu alternatif bahan baku pembuatan Jalur yaitu Bintangur (Callophyllum soulattri Burm.f.) dan Balam (Macaranga conifera (Rch.f. & Zoll) Mull.Arg) diawetkan menggunakan senyawa boron dengan metode infus dan bandage-wrapping. Sebagai kontrol, satu pohon dari masing-masing jenis juga ditebang dan diuji. Sampel kayu yang digunakan dibagi menurut posisi aksial pohon (pangkal, tengah, dan ujung) untuk diamati sifat kimia dan sifat mekanis dengan masing-masing tiga ulangan. Hasil penelitian menunjukkan bahwa posisi aksial mempengaruhi sifat kimia kayu Balam dan Bintangur secara siginifikan pada kadar lignin (30-36%) dan kadar alfa selulosa (48-52%). Secara umum, sifat mekanis yaitu Modulus of Rupture (MOR) dan Modulus of Elasticity (MOE) meningkat secara signifikan setelah diawetkan, kecuali pada Bintangur untuk metode bandage-wrapping. Hasil analisis sidik ragam dan uji lanjut menunjukkan bahwa perlakuan infus memberikan pengaruh nyata yang positif terhadap sifat kimia dan mekanis kayu Bintangur, sehingga pohon Bintangur yang telah diawetkan menggunakan metode infus dapat direkomendasikan sebagai alternatif bahan baku pembuatan Jalur
