Abstract

Abstract The increase of incidence of natural disasters over the past two decades, spawned many ideas about disaster risk reduction impacts both in terms of social and engineering, including in the field of transport evacuation. The rules of scientific developments in the field of transport modeling evacuation typically rely on natural disasters as well as the movement of traffic during the evacuation process. Concept model of transportation for evacuation is divided in two parts, the first focusing on the performance of the road network and the second on the behavior of individual refugees. Based model of transportation refugee behavior has the advantage that individual refugee can be added capabilities and knowledge of the evacuation; only in this concept study is very limited area coverage. Then the concept of performance based transportation model has the advantage of the road network can capture the phenomenon of the movement of traffic as a result of the evacuation on a large scale, in which the main results of simulation in the form of evacuation time and the identification of network vulnerability, only this model require accuracy in data collection, analysis and calibration process. The application of the concept of performance-based model of the road network in the case of disaster evacuation in Indonesia is very applicable at the level set evacuation routes, where the system optimized and user optimized is part of the scenario modeling to optimize its performance. Keywords: model of transportation, disasters, evacuation, network, refugees  Abstrak Peningkatan kejadian bencana alam selama dua dasawarsa terakhir melahirkan banyak gagasan mengenai pengurangan dampak risiko kebencanaan baik dari sisi sosial maupun teknis, termasuk pada bidang transportasi evakuasi. Perkembangan kaidah keilmuan dalam bidang pemodelan transportasi evakuasi bergantung pada tipikal bencana alam serta pergerakan lalulintas saat proses evakuasi. Konsep model transportasi untuk evakuasi dibagi dua bagian, pertama fokus pada kinerja jaringan jalan dan kedua pada perilaku individu pengungsi. Model transportasi berbasis perilaku pengungsi memiliki keuntungan, yaitu individu pengungsi dapat ditambahkan kemampuan dan pengetahuan akan evakuasi, hanya pada konsep ini cakupan wilayah kajiannya sangat terbatas (mikro).

Abstract

Abstract This paper presents a modified optimal controller for stabilizing a multimachine power system. The design method does not need the specification of weighting matrices. The eigenvalues of electromechanical modes would be shifted to a pre-specified vertical strip. For practical implementation, the proposed method design using an optimal reduced order model whose state variables are torque angles and speeds. The reduced order model retains their physical meaning and is used to design output feedback controller that takes into account the realities and constraints of the electrical power systems. Effectiveness of this controller is evaluated and example, a multimachine power system is given to illustrate the advantages and effectiveness of the proposed approach. Keywords dynamic stability, strip eigenvalue assignment, power system stabilizer, optimal reduced-order model, output feedback excitation control

Abstract

Based on the family theory of structural functionalism, family is the first and the main porosity of human resource development. Family is the basic unit of society. The objectives of this study were to develop a measurement of family strength with high reliability and validity and to formulate policy implications to increase the family strength. 233 families from Leuwiliang district (19 villages) and Cibungbulang district (15 villages) were analyzed. Family strength data consisted of informations on physical resources, non-physical resources, family problems, copping mechanism, physical well-being, social welll-being, and psychological well-being. Applying Alpha Cronbach analysis, the family strength measurement had internal consistency coeficient of reliability 0.7 and applying factor analysis and Lisrel (Linear Structural Relationship) shared that there were there major latent variables of family strength, viz physical, social, and psychological. Strengthening the family should be an entegrated part of social economic, and family funcitioning development.
