Pest risk analysis for Bactrocera invadens : Guidelines on Pest Risk Analysis

Stripping related moisture damage has been recognized as one of the major pavement distresses since the early 1990s. The main objective of this study is to establish an effective test protocol to quantify moisture susceptibility of asphalt pavements. To this end, selective test methods (Texas Boiling test, Tensile Strength Ratio, Retained Stability, and Hamburg Wheel Test), and procedures based on surface chemistries and molecular-level mechanistic properties have been investigated in this study. Firstly, a comprehensive list of literature related to moisture damage in asphalts was reviewed. Based on the literature review, a detailed project plan and test matrix were developed. Binder samples originated from two different crude sources were collected. The moisture resistance related tests such as static contact angle measurements and Texas Boiling tests were conducted. Besides, asphalt binders’ nanomechanical properties using an Atomic Force Microscopy (AFM) and surface chemistries using a static contact were evaluated in the laboratory. Based on limited test data and analysis, it is concluded that there does not exist any single test method that all agencies are comfortable and equipped to follow in their daily work as each technique has some merits and demerits. However, the Texas Boiling test is found to be the simplest method that requires minimal time and resources. On the other hand, surface chemistry and atomic force microscope-based techniques are becoming popular among researchers and pavement professionals. Findings of this study are expected to help ARDOT in selecting an appropriate moisture resistance test method that is simple, reliable, and easy to implement in their routine work

Property Development Risk Analysis Mandalika Resort Lombok Tourism Area

The role of the property sector to the national economy is very important. Not only its role in absorbing labor but also contributions to improving national economic growth. Great relevance to other sectors of the economy also makes the property sector requires strict protection and supervision of various parties, especially the government. It aims to prevent systemic risk due to the fall of the property sector to other economic sectors. Risks and uncertainties always occur in property development. The risk of an effect on every stage of the process of the development of ideas, feasibility studies, commitment to the construction and operation phase. The risk management process is generally a continuous and iterative process, even every kind of development is different and unique properties. This study aims to identify sources of risk, risk factors, the level of hazard, vulnerability level, the level of capacity and determine the priority risks in property development process. Steps being taken in this study include: the identification of sources of risk, the stage of identification of risk factors, the stage of identification of the level of hazard, the stage of identification of the level of vulnerability, the stage of identification of the level of capacity, the stage of risk analysis and risk priority index ( IPR). Conceptually, the proposed method in this study refers to the key measures of risk management that includes identification, qualitative risk analysis in the process of property development. Data collected through interviews and questionnaires by resource persons involved in property development in the tourism area Mandalika Resort Lombok in West Nusa Tenggara Province. Results of research on the development of the area Mandalika Resort Lombok can be concluded that the stages of development that are most at risk is the stage of an idea (IPR = 0.152), followed by the stage of feasibility (IPR = 0.067), then the commitment stage (IPR = 0,036), construction (IPR = 0.026) and stage management (IPR = 0.010). The results of this assessment indicate that the idea stage is the stage of development of the property are recommended to get treatment or priority risk response. Concluded the process of property development in the region Mandalika Resort Lombok is not worth continuing before risk mitigation that is unacceptabl

Environmental Health Risk Analysis Exposure to Nitrogen Dioxide (No2) and Sulfur Dioxide (So2) on Street Vendor in Ampera Terminal Palembang 2015

Background: Terminal is a location that generates air pollution as a result of transport activity performed. The use of motorized transport will produce a wide range of gases including NO2 and SO2. At certain concentrations of NO2 and SO2 can have an effect on health disorders for example respiratory problems, throat irritation and eye irritation.Methods: This study was a descriptive study of environmental health risk analysis method. Eighty four traders were sampled in this study. Simple random sampling was used as sampling technique. The variable used is the concentration of NO2, SO2 concentration, Inhalation Rate (R), exposure time, frequency of exposure, duration of exposure, weight, time period average-average, RFC, risk level. Univariate data analysis techniques. And then the data is presented in tabular form and narrative to interpret the data. Result: The street vendors in Terminal Palembang Ampera has a weight of less than 65.57 kg by 54.8%, exposure time ≤8 hours/day by 54.8%, the frequency of exposure ≤362 days/year amounted to 98.8 %, duration of exposure ≤10 years of 57.1%, intake NO2 ≤0.00132 mg/kg/day by 50%, SO2 intake 0.00677 mg/kg/day by 50%, NO2 RQ>1 at 0%, SO2 RQ>1 amounted to 11.9%, SO2 RQ>1 male sex-men by 80%, and SO2 RQ>1 is derived from the four measurement points by 40%. Conclution: This research concluded that exposure to Nitrogen Dioxide (NO2) to street vendors at Terminal Ampera Palembang does not pose a risk, whereas exposure to Sulfur Dioxide (SO2) provides risk to 10 street vendors in Terminal Ampera Palembang

The role of trust and risk perception in current German nuclear waste management

One of the lessons learned in various countries that have to deal with spent nuclear fuel is that finding a proper place and siting a repository for high-level nuclear waste (HLW) cannot be achieved without public consent. After decades of obstruction, Germany recently launched a new, participatory, site-selection process for the disposal of HLW in deep geological formations. Nonetheless, significant opposition is assumed. Therefore, citizens’ trust in the procedure and the agents involved may be paramount. We conducted an online survey (N ≈ 5000) in March/April 2020 to test a theoretical model on trust, perceived risks and benefits, and acceptance. We differentiated acceptance as a dependent variable according to distinct phases: the procedure, a possible decision on a disposal location, and the repository facility itself. The results show that trust is mainly important for explaining acceptance of the ongoing procedure and less so for the acceptance of the decision or the repository facility itself. Moreover, our investigation of the sample using a cluster analysis reveals characteristic patterns of trust, risk perception, and acceptance by three clusters: a cluster focusing on risk perception, an ambivalent cluster, and an indifferent cluster. Trust is lowest in the risk-focused cluster and highest in the ambivalent cluster

Quarantine Risk Analysis

Australia’s quarantine policy is based on the concept of manageable risk, which is underpinned by quarantine risk analysis, which this article examines with particular reference to recommendations of the 1996 Australian Quarantine Review. Quarantine risk assessment addresses disease concerns associated with any particular proposed import and may also require detailed examination of possible economic and environmental effects. The degree of quantification varies, and more quantitative approaches may be either deterministic or stochastic. Assessments consider both the probability of an event occurring and its consequences, including the direct economic effect of any introduction of an exotic disease.International Relations/Trade,
