Abstract

Grid computing provides high computing power, enormous data storage, and collaboration possibilities to its users. Grid computing is currently in the midst of evolving standards, inheriting and customizing from those developed in the high performance, distributed, and recently from the Web services community. Grid computing is widely regarded as a technology of immense potential in both industry and academia. Which this interest, security become necessery to provide authentication, authorization, resource protection, secure communication, data integrity, trust management and network security. This paper tells about progression of the security system on grid computing by conducting a survey of existing paper and applications have been developed.

Abstract

In order to fulfil the high water demand in Banda Aceh City, the Lambaro Water Treatment Plant (WTP) has been operating above its designed capacity. The produced and distributed water quality is decreasing in term of turbidity, as well. It is indicated by some events that the distributed water exceeds the allowed limit. The additional burden is that due to rainy season and human activities at river upstream, the raw water turbidity is higher than expectation in several occasions. This study is conducted to evaluate the influence of production flow rate and raw water turbidity on distributed water turbidity. The data used in this study is acquired from the SCADA system with time range from January to May 2014.

Abstract

Abstract: Diabetes mellitus is a chronic disease characterized by hyperglycemia for long time. Hyperglycemia is proven increase oxidative stress due to the production of reactive oxygen species that exceeds the ability of the natural antioxidant defenses, causing deficiency and insulin resistance. In this study, the effect of propolis as an antidiabetic was observed based on qualitative analysis of incision histology. 55 male mice (Mus musculus SW.) were divided into 5 groups: KN (normal control), P1, P2, P3 and KDM (diabetes control) induced diabetes with alloxan dose 200 mg/kg bw intraperitoneally. Propolis solution 50, 100 and 175 mg/kg bw given to P1, P2 and P3, while distilled water was given to KN and KDM by oral gavage for 21 days. Pancreatic incision histology is done every 7 days. Results of the qualitative analysis of histological cuts showed that the diameter of the islets of Langerhans in P1, P2 and P3 is smaller than KN (diameter 100-200 m). The heaviest pancreatic damage demonstrated by DM with no propolis treatment. Repairing of damage in the islets of Langerhans in mice treated with propolis showed that propolis potentially as an antidiabetic . Key words: diabetes, propolis, histology, pancreas, antioxsidan, alloxan Abstrak: Diabetes mellitus adalah penyakit kronis yang ditandai dengan hiperglikemia untuk waktu yang lama. Hiperglikemia terbukti meningkatkan stress oksidatif akibat produksi reactive oxygen species (ROS) yang melebihi pertahanan antioksidan alami sehingga menyebabkan defisiensi dan resistensi insulin. Pada penelitian ini dilihat peran propolis sebagai antidiabetes berdasarkan analisis terhadap sayatan histologist mencit. Sebanyak 55 ekor mencit (Mus musculus SW.) jantan dibagi menjadi 5 kelompok, yaitu KN (kontrol normal), P1, P2, P3 dan KDM (kontrol diabetes) yang diinduksi DM dengan pemberian dosis alloxan 200 mg/kg bb secara intraperitoneal. Larutan propolis 50, 100 dan 175 mg/kg bb diberikan kepada P1, P2 dan P3 sedangkan akuades diberikan kepada KN dan KDM secara oral gavage selama 21 hari. Pembuatan sayatan histologi pankreas dilakukan setiap 7 hari. Hasil analisis kualitatif sayatan histologi menunjukkan bahwa diameter pulau Langerhans pada P1, P2 dan P3 lebih kecil dibandingkan dengan KN (diameter 100-200 μm). Kerusakan pankreas terberat ditunjukkan oleh kelompok DM yang tidak mendapatkan perlakuan peropolis. Perbaikan kerusakan pulau Langerhans pada mencit yang diberi perlakuan propolis menunjukkan bahwa propolis berpotensi sebagai antidiabetes.

Abstract

Rangka (tulang) merupakan struktur penting penyusun tubuh manusia. Terdapat beberapa penyebab yang dapat mengakibatkan kelainan-kelainan pada tulang yang kemudian menggangu efektifitas fungsi tulang. Dalam hal ini patah tulang (fraktur) dan pengapuran tulang (osteoporosis) merupakan 2 kondisi yang sangat sering ditemukan. Pada penelitian ini akan dilakukan pengujian metode pengolahan citra digital dengan analisis tekstur pada penentuan kondisi tulang femur. Secara umum, sistem pengenalan kondisi tulang femur tersebut terdiri dari dua bagian utama, yaitu ekstraksi ciri menggunakan analisis tekstur yang menghitung nilai-nilai statistik citra bersasarkan histogramnya serta klasifikasi dengan metode K nearest neighbor (KNN). K-NN merupakan metode pengenalan objek berdasarkan perhitungan jarak terdekat dengan data pembelajaran. Pada kondisi fraktur ekstraksi ciri dengan operasi morfologi menunjukkan adanya diskontinuitas, hal ini yang kemudian akan menjadi indikasi pada kondisi femur fraktur, begitu pula dengan pengenalan morfologi pada kondisi lainnya. Adapun hasil pengujian dan analisis simulasi sistem menunjukkan bahwa pengujian secara terpisah pada masing-masing kondisi memiliki nilai akurasi yang lebih tinggi dibandingkan pengujian secara bersamaan. Untuk pengujian osteoporosis memiliki nilai akurasi tertinggi yaitu 90%. Perbaikan metode pada tahap pre-processing diharapkan mampu meningkatkan nilai akurasi yang diperoleh begitu juga dengan penambahan jumlah data yang digunakan. Kata kunci :

Abstract

Telah dilakukan perluasan model black hole schwartzchild dengan pendekatan metrik yang gayut waktu. Selain itu, dianalisis pula konsekuensi fisis akibat black hole bergerak dengan kecepatan seragam terhadap pengamat. Hasil yang di luar dugaan adalah ternyata horizon peristiwa terus mengalami perluasan bagi pengamat bila black hole mengalami gerakan dengan kecepatan seragam. Perluasan model ini pada akhirnya menunjukkan terjadinya pergesaran biru (blue-shift).

Abstract

QSAR studies had done on derivatives of triazolopiperazine amide as inhibitors DPP IV enzyme that causes diabetes mellitus type 2. The studies had began by modeling the structures of the derivatives of triazolopiperazine amide and calcutating the descriptors of QSAR by semiempirical AM1 method which available on HyperchemÒprogram. QSAR analysis had done by multilinear regression method analysis which is available on SPSSÒprogram using electronic and molecular parameters. The best QSAR equation model for method of semiempirical AM1:-log IC50 =  152.252 + (18,.295*qC1) + (2.343*qC5) + (2263.448*qC9) +  (1662.252*qC10) – (350.806*qC15) + (639.687*qO25)+ (6.515*EH)n = 18; r2 = 0.712; adjusted r2 = 0.510; Fhit/Ftab = 1.124; PRESS = 0.006 The main side of the compound can be determined through the equation. It can be used to study in preventing the disease of DM2 by inhibiting of enzyme DPP IV.

Abstract

This research studies about measurement of environmental physical characteristics such as temperature, humidity, and solar radiation which had done in strawberry field of Purbalingga, Jawa Tengah. The measurement had done to determine physical data values in the field and to give additional data for increasing the harvest productivity. The data had been aggregated by direct measurement in the field as long as 24 hours. Thus, the data are converted into a model which shows interpretation between the charracteristic parameter and time. Its result is used to make nonlinear interpolation in order to predict unmeasured values in this study. The study also measures the mass of the fruits for several sample. The results are analized comprehensively in environmetal physical characteristics and the fruits quality based on the additional data. These show that the ideal elevation field is 1297 m msl, temperature about 17.1-24.7 oC, humidity about 40.2-90.5 %, solar radiation ± 11 hours which gained at 06.00-17.00 WIB is 0-38x103 lxand fuits average mass in 16.779 g/fruit

Abstract

Conducting data analysis on a large set of documents is not an easy task. The common stages are document filtering, document selection, and document clustering. Clustering is a technique used in data mining to find groups of data that do not have a natural grouping. There are many clustering algorithm have been introduced, and two of them are K-means and K-medians. Both methods classify documents based on the proximity of words weighting between documents. This study aims to compare the quality of the clusters produced by K-means and K-medians. The results show that K-medians obtain a better cluster quality when compared to K-means. However, it takes more time to cluster.
