Desain Kontroler PID-Genetic Algorithm untuk Sistem Pengaturan Level Air Steam Drum pada Pembangkit Listrik Tenaga Uap (PLTU)

Perubahan laju aliran uap menimbulkan gangguan pada sistem pengaturan level air steam drum. Level air dijaga pada titik tengah ketinggian drum atau disebut Normally Water Level (NWL), agar uap yang dihasilkan memenuhi spesifikasi serta tidak merusak peralatan pada pembangkit. Pada umumnya, sistem pengaturan level menggunakan kontroler PID konvensional. Namun, adanya gangguan dapat menyebabkan performa sistem dengan kontroler PID konvensional tidak mampu memenuhi spesifikasi. Kontroler PID-Genetic Algorithm (PID-GA) diterapkan untuk mengatur level air steam drum agar berada pada titik NWL ketika terdapat gangguan. Sistem pengaturan menggunakan kontroler PID-GA mampu meredam gangguan berupa beban minimal, nominal, dan maksimal, yaitu dengan perturbation peak masing-masing sebesar 0,18 m; 0,22 m; dan 0,26 m

Gambaran budaya masyarakat Brunei dalam kumpulan puisi Diam-Diam karya K. Manis

Kajian ini merupakan sebuah kajian kepustakaan yang bertujuan mengenal pasti dan membincangkan gambaran budaya masyarakat Brunei dalam kumpulan puisi Diam-Diam (2010) karya K. Manis. Kumpulan ini mengandungi 73 buah sajak. Data kepustakaan dianalisis dengan memanfaatkan kaedah analisis kandungan bersandarkan konsep budaya yang dikemukakan Edward B. Tylor (1974) dan juga yang diajukan oleh A. Aziz Deraman (2005). Hasil analisis mendapati enam gambaran budaya masyarakat Brunei yang diangkat penyair. Enam gambaran budaya masyarakat itu adalah yang bergantung hidup pada sumber pertanian, masyarakat yang berhadapan dengan musibah, gambaran akan adat orang Besar-Besar, gambaran budaya berbudi pada tanah, gambaran budaya warga bernegara dan gambaran perubahan budaya. Enam gambaran itu dapat dikelompokkan kepada tiga aspek kehidupan masyarakat iaitu pertanian, alam sekitar dan hidup bernegara. Dapatan kajian juga merumuskan tiada gambaran budaya yang berkait dengan aspek perdagangan antarabangsa, petroleum, politik dan pendidikan, walhal kegiatan-kegiatan ini merupakan teras kemajuan dan pembinaan masyarakat bernegara di Brunei. Berdasarkan dapatan ini, beberapa cadangan wajar diambil perhatian khususnya kepada pihak Dewan Bahasa dan Pustaka Negara Brunei Darussalam. Antaranya usul supaya dilaksanakan kajian lanjut tentang budaya masyarakat Brunei yang juga perlu diperluaskan kepada kumpulan-kumpulan puisi penyair dan genre-genre lain yang melibatkan prosa tradisional dan moden. Ia pasti sahaja memberikan sumbangan besar kepada khazanah kesusasteraan Brunei mahupun kesusasteraan Melayu Nusantara

Development of MIS Courses through knowledge Management: An e-learning project for Online Delivery by the Ministry of Education in Jordan

In this era of information, traditional practices, technologies, skills, and knowledge are becoming obsolete at a much faster pace than ever before. The technological pace and the advent of the knowledge society will set in the next years the new context for e-learning evolution. This makes lifelong learning a necessity for everyone. An e-learning project is a promising solution to the demand for a flexible means of delivering knowledge to educate a large number of people over a vast area. MIS-Online project is an e-learning project in ministry of education in Jordan. The main objective of the project is to develop e-materials based on the curriculum of the Management Information Stream (MIS), which is an academic stream in the secondary schools. The adopted pedagogical model is project-based learning, through the development of different scenarios that link to different them

Pengaruh Perendaman Larutan KOH Dan NaOH Terhadap Kualitas Alginat Rumput Laut Sargassum Polycycstum C.A. Agardh

Sargassum polycystum seaweed is a type of brown algae that contains alginate. Alginate from S. polycystum did not optimally and alginate has an importnat role from a variety of industries. Alginate ekstraction obtained by submersion wes using NaOH and KOH solvent, then continued using Na2CO3 solvent. The purpose of this research was to determine the effect of immersion with KOH and NaOH with concentration 0,3%, 0,5% and 0,7% solution to the quality alginate from brown seaweed S. polycystum. Experimental design used was Rancangan Acak Lengkap (RAL). The results showed that aging of the KOH solution has a lower water content and higher viscosity than NaOH solution. The concentration of the solution used also affects the yield, moisture content, ash content and viscosity alginate S. polycystum. The higher concentration of the solution then the yield, moisture content and lower ash content, while viscosity alginate increased. The best results obtained in the treatment with a solution of KOH concentration of 0.7%

Dynamic Behavior of Jacket Type Offshore Structure

Unlike structures in the air, the vibration analysis of a submerged or floating structure such as offshore structures is possible only when the fluid-structures is understood, as the whole or part of the structure is in contact with water. Using the commercial F.E.A. program ANSYS (v.12.0) (to model the Winkler and Brick-full bond models) and program ABAQUS(v.6.9) (to model the Brickinterface model), the stress matrix considering a dynamic load was superposed on the stiffness matrix of the structure. A time domain solution is recommended, using the generalized Morison’s equation by FORTRAN90 program to construct a program to calculate the wave forces, and Airy's linear and Second Order Stoke's wave theories are employed to describe the flow characteristics by using MAPLE13 program (to solve and apply the boundary conditions of the problems on Laplace's equation), and the results are compared and discussed. Both free and forced vibration analyses are carried out for two case studies

Comparison of domestic violence and its related factors in pregnant women in both urban and rural population in Zarand city, 2014

Background and aims: Domestic violence is a public cultural and health-related problem that its prevalence varies among different societies and affects pregnancy outcomes in direct and indirect fashions. The aim of this study was to compare domestic violence and its related factors in rural and urban pregnant women in Zarand. Methods: In this cross-sectional study, 400 pregnant women referred to Zarand’s urban and rural healthcare centers during 2014 were included by simple (convenient) sampling method. Demographic and CTS-2 questionnaires were given to the samples. Data was analyzed by means of the independent t-test, Kruskal-Wallis and Friedman’s statistical tests. Results: The study results showed that domestic violence the mean of violence in urban and rural pregnant women was 1.82±2.86 and 1.00±1.60 in physical domain, 2.93±1.61 and 2.04±1.46 in psychological domain, 3.87±2.93 and 1.99±2.89 in sexual domain, and 1.43±1.89 and 2.29±2.36 in injury-resulted violence, respectively. A significant difference between urban and rural groups in physical, psychological and sexual violence was observed (P<0.01), but there was no statistically significant difference in injury-resulted violence between two groups. Woman’s age, spouse’s age and education level, economic (financial) status, number of pregnancies and children, marriage duration and spouse’s addiction (drug/substance abuse) were significantly related to the types of domestic violence (P<0.05). Conclusion: According to project results about high domestic violence, it is recommended screening violence in the all health and therapy centers
