Talking about elections cannot be separated from the implementation of campaigns, because campaigns are a very important process in holding general elections. An election campaign is activity participants or other parties appointed by to convince voters offering vision, mission, program and self-image participants. The aim this research determine supervisory mechanism Election Supervisory Agency minimizing violations prohibitions obtain an overview obstacles monitoring prohibitions. method...

The guidance of endothelial cell organization into a capillary network has been long-standing challenge in tissue engineering. Some research efforts have made to develop methods promote networks inside engineered constructs. Capillary and vascular that would mimic blood microvessel function can be used subsequently facilitate oxygen nutrient transfer as well waste removal. Vascularization engineering construct is one the most favorable strategies overpass supply limitation, which often major...

Natural rubber composite has been continuously developed due to its advantages such as a good combination of strength and damping property. Most carbon black (CB)/Natural Rubber (NR) were used material in tyre industry. The addition CB natural is very important enhance the rubber. particle loading different structure can affect strength. effects 20, 25 30 wt% structures N220, N330, N550 N660 series on tensile property investigated. result shows that elastic modulus rubber/CB was higher than...

Produk perkebunan merupakan salah satu komoditas yang sangat penting Indonesia. Duku adalah salas produk musiman menjadi sumber pendapatan ketika panen. Namun, umur simpan duku pendek, batas penyimpanan buah tidak lebih dari minggu. Buah akan mengalami perubahan pada warna buah, segar kecoklatan 3 sampai 5 hari pasca Berubahnya tersebut tentunya dapat menurunkan kualitas dan harga tersebut. Pendeknya sulitnya penjualan duku. Penelitian ini melakukan pengklasifikasian sesuai dengan...

Abstract We describe an in vitro culture process that uses 100‐μm diameter poly(ethylene terephthalate) monofilaments as contact guidance of human umbilical vein endothelial cells (HUVECs) to orient the development microvessels a 3D environment. Untreated fibers, distanced either by 0.05, 0.1, 0.15, or 0.2 mm were first covered with HUVECs and then sandwiched between two layers fibrin gel containing HUVECs. After 2 4 days culture, cell connections evaluated. Cell formed massively along...

Angiogenesis, the formation of micro-vascular network from preexisting vascular vessels, has been studied in connection to normal developmental process as well numerous diseases. In tissue engineering research, angiogenesis is also essential promote inside engineered constructs, mimicking a functional blood vessel vivo. Micro-vascular can be used maintain adequate oxygenation, nutrient transfer and waste removal. One problems faced by researchers find suitable vitro assays methods for...

Porous tantalum has been used as an orthopedic implant for bone defects it a good corrosion resistance and fatigue behaviour properties. However, there are some reports on the rejection of porous Ta after implantation. Those clinical cases refer to less bioactivity metallic-based materials. This study aims evaluate hydroxyapatite coated uncoated Tantalum in order improve biocompatibility osseointegration. was metallic-base substrate coating done using plasma-spraying technique. Scanning...

The damage of bone tissue may cause malfunction human load-bearing system. To date, hydroxyapatite (HA) is one the most potential materials to repair damages and restore function. It has been produced from both synthetic chemical natural resources, including limestone. In this paper, properties made CaCO3 limestone was investigated in a function sintering time, i.e., 2, 3 4 hours, temperature, 600, 800 1000°C. preparation HA included crushing, meshing, grinding sintering. powder then...

Polyacrylonitrile (PAN) is a synthetic biocompatible polymer used as filtering membrane in hemodialysis and for enzyme immobilization purposes. However, its potential usage other medical applications limited due to poor hydrophilicity. To overcome this problem, two groups of electrospun PAN fibers were treated with sodium carbonate (Na2CO3) hydroxide (NaOH), respectively at 100oC 5 minutes. Fibrin gel was then coated onto the samples before seeding human umbilical vein endothelial cells...

Material Aluminum (Al) dan paduannya telah banyak digunakan secara luas diberbagai bidang industri. memiliki sifat korosi yang baik, namun permasalahan adalah sulitnya proses penyambungan, karena adanya lapisan oksida di permukaan logam. Teknologi pengelasan gesek puntir (friction stir welding, FSW) merupakan alternatif potensial untuk diaplikasikan pada aluminum. Dalam penelitian ini, mesin freis vertikal Milko-12 difasilitasi indentor las. Proses dilakukan bahan 1100-H18 4 (empat) macam...

Glass-ceramics were fine-grained polycrystalline materials produced by controlled crystallization in the glass phase to have outstanding characteristics. The establishment of basalt from Sukadana - Lampung Province into glass-ceramic begins with process

Magnesium forms 2% in the earth's crust, magnesium is widely used industry. For example, industrial machinery and electronics, many developed field of biomedicine, especially orthopedics. about 60% present human bones, therefore it has great potential for body implants. However, necessary to increase mechanical chemical properties order be bone implant materials. Production process using squeeze casting method. Through this method, Liquid metal given hydraulic pressure, so were better. In...

Cellulose is a natural polymer contained in growing fibres, such as pineapple fibres. can be modified into cellulose acetate, that used the synthesis of acetate/polyethylene glycol (CA/PEG) membrane. The phase inversion method was this study to produce CA/PEG membranes. Variations polyethylene (PEG) concentration with ratio 1:1 where variations PEG concentrations are 2%, 5% and 8%. Acetone dimethylformamide organic solvents. Membrane morphological analysis using scanning electron microscopy...

Abstract Limestone is a mineral that mainly contained calcium oxide. has been used in manufacture industries for decades. Many researchers utilized limestone as material hydroxyapatite. Hydroxyapatite biocompatible human body and it potential to restore the damaging bone. However, hardness of hydroxyapatite low. In this research, made from disodium hydrogen phosphate dihydrate were mixed with polylactic acid. The was added source increased composite. Polylactic acid increase compatibility...

Kabupaten Ogan Komering Ilir merupakan daerah yang sebagian besar dataran rendah, yaitu rata-rata 10 m di atas permukaan laut. terdiri dari 75% lahan basah dan memiliki beberapa potensi sumber daya air salah satunya sungai.
