Sustainable Ground Improvement Technique for Geo-Disaster Mitigation

This research was motivated still many natural disasters in Indonesia. Geological disasters would always be an important issue in the Indonesian Nation as a consequence Indonesia's geological conditions unique region, rich in natural resources but full of potential disasters. Disaster handling required the participation of all components of the nation led to the importance of the massive dissemination of disaster information to all levels of society. The role of the community in the society was considered to be very strategic as agents of change. Unfortunately, the competence of members of the community who were still considered weak in disaster mitigation and counseling techniques became constraints the achievement of objectives disaster-conscious society. Increased competence was absolutely necessary and training could be selected as an option to improve competence. Research conducted using the method of research and development which was divided into three main stages. First, the needs analysis as a preliminary study, the second, the development of a model curriculum, and the third trials of the curriculum model to determine the effectiveness in improving the competence fields of geological disaster mitigation. This study was conducted to determine the curriculum development process proper training to improve competence in community-based geological disaster mitigation. The results showed that the model developed training curriculum based on the needs analysis proven effective in improving participants's competence to do counseling disaster mitigation. Pre-post test results showed an increase in the cognitive aspects of participants in Trial I and Trial II. Significant improvement occurred on the competence of counsel which showed a success rate of Trial II in improving the competence of counsel practice of training participants. Factors supporting the development of a model curriculum Extension Disaster Mitigation Training Community-Based Ground Motion were: (a) the competence of lecturers geological disaster mitigation; (B) the interests of members of community volunteers; and (c) the support of policy makers, while the factors that impeded the development of curriculum models were limited clump of competence training in geology, low educational background and knowledge of the geology and ground motion, and limited time.

Design And Construction

AbstractLa Parrilla is a tungsten and tin mine located in western Spain. The tailings facility has a total capacity for 3 Mm3 and will be executed in four different phases. The main constraint for the design and construction of the tailings dam is that it has been constructed over an existing one from the 1980s. The construction activities involved removal and substitution of the old tailings from the southern portion of the facility, ground improvement with gravel columns over an area of about 10,000 m2, and construction of the dyke’s dam. This article describes the main design and construction aspects, including monitoring, until the dam’s completion in June 2019.
