Development of reliability and probabilistic safety assessment program RiskA
No full textAbstractPSA (probabilistic safety assessment) software, the indispensable tool in nuclear safety assessment, has been widely used. An integrated reliability and PSA program named RiskA has been developed by FDS Team. RiskA supplies several standard PSA modules including fault tree analysis, event tree analysis, uncertainty analysis, failure mode and effect analysis and reliability database, etc. RiskA has several advanced features such as extensible framework, fast fault tree analysis, multiple models formats support and web-based co-modeling. Not only the overview of the architecture and basic functions of RiskA, but also the challenges and solutions in the development procedure of RiskA were introduced. The comparison between RiskA and other popular PSA codes has demonstrated that the calculation and analysis of RiskA is more accurate and efficient. Based on the development of this code package, many applications of safety and reliability analysis of some research reactors and nuclear power plants were performed

The risks of developing substance addiction for young people and the role of social work in reducing the harm of problematic substance use
No full textBakalaura darba mērķis ir noskaidrot kādi var būt vielu atkarības un problēmlietošanas rašanās riska faktori starp jauniešiem un kāda ir sociālā darba loma riska faktoru un vielu problēmlietošanas kaitējuma mazināšanā, vecuma grupā no 13-19 gadiem. Pētnieciskie jautājumi ir par to vai jaunieši apzinās un ņem vērā riska faktorus izvēloties lietot atkarību izraisošās vielas un kāda ir sociālā darba loma kaitējuma mazināšanas pieejas īstenošanā strādājot ar jauniešiem ar atkarības un problēmlietošanas risku. Pētījums tiek balstīts uz kaitējuma mazināšanas teoriju. Pētījuma metodes ir daļēji strukturētās intervijas un dzīvesstāsta intervijas. Pētījumā izmantotais izlases veids ir mērķtiecīgā izlase. Pētījuma rezultāti atklāj, ka sociālais darbs kaitējuma mazināšanai netiek pielietots darbā ar jauniešiem bieži sociālā darba praksē īpaši valsts sociālajos dienestos, bet ir pieejami pakalpojumi caur NVO. Jaunieši bieži neapzinās riska faktorus, kādi var būt vielu lietošanai un tādēļ neņem tos vērā izvēloties lietot atkarību izraisošās vielas.The purpose of this bachelor’s thesis is to ascertain what risk factors may be for the occurance of substance addiction and problematic use among young people, and what role social work plays in reducing the harm of risk factors and problematic use of substances, in the age group from 13-19 years. The research questions are whether young people are aware and take into account risk factors when choosing to use addictive substances and what role social work plays in implementing a harm reduction approach when dealing with young people at risk of addiction and problematic use. The study is based on the theory of harm reduction. The study’s methods include semi-structured interviews and life story interviews. The sample used in the study is the targeted sample. The results of the study reveal that social work to reduce harm is not used in work with young people often, especially in social work practice in public social services, but some services are available through NGOs. Young people are often unaware of the risk factors that substance use may have and therefore do not take them into account when choosing to use addictive substances

Mitigating value conflicts in large infrastructure projects in indonesia: The Case of the National Capital Integrated Coastal Development (NCICD) Plan
No full textIn the effort to address flood problems in Jakarta, the Indonesian and Dutch Government finalized a study called Jakarta Coastal Defence Strategy (JCDS) in 2011. In the study, it is concluded that an offshore solution is crucial to protect Jakarta from the threat of sea level rise in the coastal area. The collaboration between these two countries was later continued by realizing the Master Plan for the National Capital Integrated Coastal Development (NCICD). The main purpose of this master plan is to provide a long-term solution for flooding problems. In addition to the main purpose, this plan also addresses other urban problems, proposes a solution to improve the coastal zone area and facilitates socio-economic development in the area. This project encounters high resistance from public and is deemed to be controversial in the public domain as the plan includes the construction of a large protection wall enclosing the sea and land reclamation. The public perceives that this project would have fatal environmental and social impacts, including the disappearance of mangrove forest, undesirable effect on the livelihoods of vulnerable communities, etc. Hitherto the plan has remained controversial, despite formal assessment conducted by the Indonesian government and Dutch consultants, in which the plan is considered as a measure to save Jakarta from being a sinking city caused by an alarming rate of land subsidence. Noting this constant debate of the project, identifying values of stakeholders is, therefore, important to understand the underlying reasons of persistent oppositions. Hence the objective of this research is to develop an approach for mitigating conflicting values in a public project in Indonesia as the supporting tool for decision making process.To be able to understand the decision-making process and identify the values at stake, an analysis was performed based on 243 newspaper articles which were selected using the keywords: ‘giant sea wall’ and ‘NCICD’ within a time period of 57 months; from January 2011 to September 2016. From these articles, the decision-making process was constructed to analyze how the decision-making process was conducted in the past and what important aspects have been missed in the implementation of decision-making process. In addition, values of the stakeholders were also identified by analyzing the arguments set forth by diverse stakeholders.From the previous literature and analysis in this research, it has been observed that there are certain stakeholders who are necessary to be involved but are still underrepresented in the plan. Furthermore, the values which are fundamental to certain stakeholders have not been covered in the previous assessments. Therefore, in this research, the values of stakeholders are adopted as the basis of using expert methods in decision-making process in combination with the stakeholder participation method. To conclude this research, the following list is the summary of the developed approaches in which an adapted version of existing methods are used to address specific value conflict: EIA and MCA as the method to mitigate the value conflict of safety, economic development vs environmental protection (i), CBA as a method to mitigate safety, economic development, cost-recovery vs economic and welfare (general), utilities (ii), VSD as the method to mitigate value conflict between safety, economic development vs economic and welfare (affected communities), culture/ Identity (iii), and VSD as a method to mitigate value conflicts between safety, economic development vs port development (economic interest) (iv).Engineering and Policy Analysi

Pambudi Widiatmaka, ST., MT. and Supervising professor II DR. Capt. Sahabuddin Sunusi, MT., M.Mar.
Main engine at MT. Fortune glory XLI is a Diesel engine 2 tak with 6 cylinder. When sea voyage from Tg. Uban to Cilacap the exhaust gas of main engine has a high temperature increase. A high exhaust gas is visible on the thermometer contained in cylinders 2 and 3 which is normally between 300 – 400 0C reach over 5000C. Seen also on the monitor that the compression pressure cylinders 2 and 3 decreased from normally between 30 until 40 Kg/Cm2 to be less than 30 Kg/Cm2. In this case, author use SWOT analysis method, this methode use to solve thr problem based on some factor analysis, Strength, Weaknesses, Opportunity and Threats by using strategies that determined correspondence by result of SWOT analysis method sistematically. That goals to solve the problem based on strategy and critical succes factor on SWOT method. There are many causes of the effect of low compression pressure so the combustion on the cylinder not optimal, some of the causes of these causes include was broken piston rings, worn piston, worn cylinder liner, Etc. From several factors analyzed to derive a major factor of low compression pressure at MT. Fortune Glory XLI. After the analysis turned out low compression pressure caused a broken piston rings caused lubrication that is not optimally at cylinder liner. Because lack of lubrication causes direct friction between ring piston and cylinder liner and causing piston rings to wear out even cracked or broken. So the compression pressure become low and affects the performance of the main engine.
