Increasing fish consumption value should be supported by enhancing the safety and quality offish products. Microbiological level is most of importance since every food contains microorganismswhich could multiplicate due to temperature abuse and time delay during handling and processing.Risk assessment is a structurally and scientifically based approach aimed to protect consumerfrom risk (hazard) particularly microbiological hazard when consuming certain food. Microbiologicalrisk assessment of fishery products have not been structurally developed in Indonesia, eventhoughseveral initial data on hazard identification have been available. As an attempt to build an integratedrisk assessment, a model for microbiological risk of pathogenic  Vibrio parahaemolyticus inshrimp will be proposed in this article. The available data could be used as a starting point whileother required data could be collected in collaboration with other related institutions.

Abstract Motivation Generalized Read-Across (GenRA) is a data-driven approach to estimate physico-chemical, biological or eco-toxicological properties of chemicals by inference from analogues. GenRA attempts to mimic a human expert’s manual read-across reasoning for filling data gaps about new chemicals from known chemicals with an interpretable and automated approach based on nearest-neighbors. A key objective of GenRA is to systematically explore different choices of input data selection and neighborhood definition to objectively evaluate predictive performance of automated read-across estimates of chemical properties. Results We have implemented genra-py as a python package that can be freely used for chemical safety analysis and risk assessment applications. Automated read-across prediction in genra-py conforms to the scikit-learn machine learning library's estimator design pattern, making it easy to use and integrate in computational pipelines. We demonstrate the data-driven application of genra-py to address two key human health risk assessment problems namely: hazard identification and point of departure estimation. Availability and implementation The package is available from github.com/i-shah/genra-py.

Tunnels are artificial underground spaces that provide a capacity for particular goals such as storage, under-ground transportation, mine development, power and water treatment plants, civil defence. This shows that the tunnel construction is a key activity in developing infrastructure projects. In many situations, tunnelling projects find themselves involved in the situations where unexpected conditions threaten the continuity of the project. Such situations can arise from the prior knowledge limited by the underground unknown conditions. Therefore, a risk analysis that can take into account the uncertainties associated with the underground projects is needed to assess the existing risks and prioritize them for further protective measures and decisions in order to reduce, mitigate and/or even eliminate the risks involved in the project. For this reason, this paper proposes a risk assessment model based on the concepts of fuzzy set theory to evaluate risk events during the tunnel construction operations. To show the effectiveness of the proposed model, the results of the model are compared with those of the conventional risk assessment. The results demonstrate that the fuzzy inference system has a great potential to accurately model such problems.

Oil Pipeline

The oil and gas pipeline companies in China are facing unprecedented opportunities and challenges because of China’s increasing demand for oil and gas energy that is attributed to rapid economic and social development. Limitation of land resource and the fast urbanization lead to a determinate result that many pipelines have to go through or be adjacent to highly populated areas such as cities or towns. The increasing Chinese government regulation, and public concerns about industrial safety and environmental protection push the pipeline companies to enhance the safety, health and environmental protection management. In recent years, PetroChina Pipeline Company (PPC) pays a lot of attention and effort to improve employees and public safety around the pipeline facilities. A comprehensive, integrated HSE management system is continuously improved and effectively implemented in PPC. PPC conducts hazard identification, risk assessment, risk control and mitigation, risk monitoring. For the oil and gas stations in highly populated area or with numerous employees, PPC carries out quantitative risk assessment (QRA) to evaluate and manage the population risk. To make the assessment, “Guidelines for quantitative risk assessments” (purple book) published by Committee for the Prevention of Disasters of Netherlands is used along with a software package. The basic principles, process, and methods of QRA technology are introduced in this article. The process is to identify the station hazards, determinate the failure scenarios of the facilities, estimate the possibilities of leakage failures, calculate the consequences of failures and damages to population, demonstrate the individual risk and social risk, and evaluate whether the risk is acceptable. The process may involve the mathematical modeling of fluid and gas spill, dispersion, fire and explosion. One QRA case in an oil pipeline station is described in this article to illustrate the application process and discuss several key issues in the assessment. Using QRA technique, about 20 stations have been evaluated in PPC. On the basis of the results, managers have taken prevention and mitigation plans to control the risk. QRAs in the pipeline station can provide a quantitative basis and valuable reference for the company’s decision-making and land use planning. Also, QRA can play a role to make a better relationship between the pipeline companies and the local regulator and public. Finally, this article delivers limitations of QRA in Chinese pipeline stations and discusses issues of the solutions.

ABSTRAK Rumah Potong Hewan merupakan suatu bangunan yang memiliki desain dan konstruksi khusus digunakan sebagai tempat pemotongan hewan. Aktivitas kerja di RPH memiliki potensi bahaya yang dapat mengancam keselamatan dan kesehatan kerja. Berdasarkan observasi awal, RPH Kota Pekanbaru ini tidak memiliki laporan bulanan maupun tahunan mengenai data kecelakaan, dan juga belum pernah melakukan identifikasi, dan penilaian terhadap bahaya yang ada. Adapun tujuan penelitian ini yaitu untuk menganalisis keselamatan kesehatan kerja (K3) terhadap risiko bahaya lingkungan fisik di tempat kerja dengan metode “HIRARC” (Hazard Identification, Risk Assessment, and Risk Control). Jenis penelitian ini adalah kualitatif analitik. Lokasi penenlitian dilakukan di rumah potong hewan Kota Pekanbaru, penelitian dilakukan pada bulan Juli-Agustus 2020. Informan dalam penelitian ini sebanyak 6 orang, sebagai informan utama yaitu Kepala UPTD, 2 orang informan pendukung yaitu koordinator lapangan dan dokter hewan, dan informan kunci yaitu pekerja, metode yang digunakan peneliti yaitu wawancara mendalam dan observasi langsung. Berdasarkan hasil penelitian yang dilakukan potensi bahaya tingkatan risiko “Ekstrim” seperti diseruduk sapi pada proses penggiringan sapi menuju killing box, tertimpa katrol dan sapi pada proses penggantungan dan pemindahan sapi menggunakan katrol. Rumah Potong Hewan belum pernah melakukan identifikasi bahaya, penilaian risiko akan tetapi untuk pengendalian risiko sudah dilakukan beberapa upaya di rumah potong hewan, seperti SOP, Shift kerja, dan juga APD. Rekomendasi yang diberikan yaitu diharapkan sebaiknya RPH memiliki fasilitas yang berhubungan dengan kesehatan pekerja. Perlu adanya upaya pengendalian risiko secara engineering control, contohnya, membuat kerangkeng sapi. administrative control, seperti, memberikan sosialisasi, maintenance, housekeeping dan inspeksi, terhadap alat, mesin dan pekerja. ABSTRACTSlaughterhouse is a building having the design and construction specifically used as animal slaughterhouse. Slaughterhouse’s work activities have potential of hazards which can cause harm to workers’ safety and health. Based on pre observation, the slaughterhouse in Pekanbaru does not have any monthly and annual report about the data of accident. This livestock production also has no doing identification and assessment of hazard. The purposes of this study are to analyze occupational health and safety toward risk of danger physical environment at work, this study uses Hazard Identification, Risk Assessment, and Risk Control “HIRARC” method which using likelihood and severity level of each hazard as references to define a risk value. There are 6 informants the maininfromants is a UPTD head, 2 supporting informants are the field coordinator and venetarian, and the key informant is a worker, The methode that use in this study is interview And observation. The study shows that the most extreme are getting hit by a cow in cattle herding to killing box, falling of a cow hoist material from conveyor railing in shackling and hoisting process. Slaughterhouse has never done hazard identification and risk assessment. However, for risk control have done several attempts in slaughterhouse, such as Standard Operating Procedures, work shifts, and Personal Protective Equipment. Recommendation is given that the slaughterhouse should has facilities related to health of workers. It needs an effort to risk control through engineering control such as making cow cages, administrative control, such as giving socialization, maintenance, housekeeping and inspection of tools, machines and workersKeywords : Slaughterhouse, Hazard, Risk, Physical Environtmen, HIRARC.
