SIMULASI PEMODELAN SISTEM PEMBANGKIT LISTRIK TENAGA HYBRID (PV - WIND TURBINE) MENGGUNAKAN PERANGKAT LUNAK HOMER

Pertumbuhan populasi dan ekonomi yang semakin meningkat sebanding dengan kebutuhan akan energi listrik. Hal ini mengharuskan perusahaan listrik untuk mengikuti kebutuhan yang di minta oleh masyarakat, akan tetapi dengan terbatasnya ketersediaan pembangkit yang ada dan juga sebagian besar masih menggunakan pembangkit dari bahan bakar fosil maka ini mengakibatkan penurunan efisiensi dari pembangkit tersebut untuk itu perlu adanya pembaharuan pembangit listrik yaitu dengan pembangkit energi terbarukan. Penelitian ini dibuat untuk membahas potensi dari pembangkit listrik tenaga hybrid (PV-Wind Turbine) dan memprediksi dalam kurun waktu jangka panjang. Metode yang dilakukan untuk penelitian ini adalah dengan mensimulasikan pembangkit lisrik hybrid(PV-Wind Turbine) dengan menggunakan perangkat lunak HOMER dan berdasarkan strategi kontrol Load following dan Cycle charging. Dimana hasil yang dicapai dari metode ini adalah optimalisasi berdasarkan strategi Load following dan Cycle charging sehingga didapatkan karakteristik dari segi teknis, segi ekonomis maupun dari segi emisi yang dikeluarkan. Dari segi teknis kedua strategi memiliki renewable fraksi yang sudah melebihi 50%, dari segi ekonomis LF dengan NPC $215.879 dan CC$222.532. Sehingga diiharapkan penelitian ini dapat bermanfaat sebagai acuan pemerintah dalam perencanaan pembangunan pembangkit listrik menggunakan energi baru lagi terbarukan

‘And the winner is …’

With a commitment to artistic excellence film festivals are set apart from regular exhibition venues and commercial interests. Although one of the festivals’ key functions is to add value, few academics have carried out empirical research on festival prizes and prestige. In this article we aim to contribute to the understanding of film festivals as a network of cultural capital by reconstructing what happens behind the scenes of the Joris Ivens competition of the International Documentary Film Festival Amsterdam, analyzing, among others, jury reports and interviews with jurors. In our analysis we draw attention to the various subjective and contingent elements in the selection process as well as to the influence of the festival context in setting (expert) evaluation standards. We identify recurring elements in the jury deliberations and, following our findings, argue that festivals are not mere barometers of changing norms, but forces that drives, shape and legitimize change

Effect of E-beam sanitation of surface mould cheese on texture and sensory attributes

The effects of E-beam radiation at doses up to 3 kGy on mechanical and colorimetric parameters and sensory attributes of Camembert and Brie cheeses and their behaviour during storage at 4 and 14 °C were studied using response surface methodology. Immediately after treatment, no significant differences (p > 0.05) in adhesiveness, springiness and chewiness were found in either of the cheeses. However, hardness, cohesiveness, gumminess and breaking force decreased in Camembert cheese as the dose increased, while values for the Brie samples remained fairly constant. Nevertheless, no significant differences (p > 0.05) between untreated and treated samples after two weeks of storage were detected. Minor changes in the colour parameters were due to the E-beam treatment even at 3 kGy and then minimized during storage. A similar behaviour was observed in sensorial parameters. Because the dose studied was higher than that required to achieve the food safety objective according to EU and USA regulations, it was concluded that E-beam treatment is a useful method for sanitizing soft mould-ripening cheeses with negligible changes in the sensory quality and rheological properties.Sección Deptal. de Farmacia Galénica y Tecnología Alimentaria (Veterinaria)Fac. de VeterinariaTRUEpu
