This article investigates the effectiveness of the posture movement of a pressing machine to mold the cassava crackers. This study is undertaken at Karya Lestari Jaya, which is one of SMEs in Tulungagung, East Java Indonesia. This industry has a problem with the new manual pressing machine which is too stiff and heavy to be handled. The operators complain about feeling sore at upper and lower arms. It means that this activity has a poor posture when the operators are working. This research aims to identify the ergonomic risk factors for the pressing machine and to determine the best recommendation suggested by the operators and the owner of SMEs-Karya Lestari Jaya. We undertake a case study by collecting data from the observation. We analyze the observation data by RULA (Rapid Upper Limb Assessment). Then, we interview eight interviewees to attain the attribute requires in improving the machine. Also, we analyze the best recommendation by using AHP (Analytic Hierarchy Process).  This study yields the score of RULA is 6 which means the posture in pressing the dough or the working facilities needs to be improved immediately. The results from AHP shows the best recommendation is adding the pneumatic system to the pressing machine to lighten the lever. Ultimately, this finding can be beneficial for the company by figuring the posture and evaluating improvement for the machine.

Objective: This paper uses the Analytic Hierarchy Process (AHP) to rank main actions and their associated task areas outlined in the Hyogo Framework for Action (HFA) in the case of Nigeria. The focus is on three major challenges namely (1) stakeholder inclusiveness, (2) capacity building and communication and (3) local adaptation. Methods: The perceptions of a sample of 26 field disaster management experts on the HFA were studied and analyzed using AHP. The study found that "Disaster Preparedness" is the most important expected goal followed by "Risk Assessment and Early Warning." Results: Their priority indices are 0.258 and 0.219, respectively. "Local/City Governance" however, shows poor performance with a priority index of 0.085. Monte Carlo simulation was further applied to examine the robustness of the AHP assessments. Conclusion: The results are indicative of the perceptions of the performance levels attained and the areas that need improvement.

The exploitation of wind energy for generating power is taking a major role in the electricity consumption globally. Proper utilization of wind resource could maximize its capacity factor and minimize electricity costs. This article will provide a tool for minimizing wind energy project risks for further investment to consider and choosing the best location in Jordan. For this process, the following risk factors were first identified: strategic management errors, transport, construction, operation and maintenance, marketing and policy risks. Then, using analytic hierarchy process, a complete risk assessment model was built and applied to two alternatives, Ras Moneef and Al-Fujaij. The results showed Al-Fujaij as a better potential location with relative importance to the factors compared with Ras Moneef. Among these risk factors, strategic and business risk have the highest impact, which can be mitigated by performing effective management, accurate contracting, and conducting emergency plans. It is believed that such results could benefit the project stakeholders to be aware of the risk items to be invested in while considering the project funding limits. The proposed framework also enables decision makers to create a reasonable fund and set achievable objectives for the project.

Droughts occur from a combination of natural factors and human activities rather than just a single natural cause. Spatial factors have also heavily influenced the causes of draught. This study was conducted in the Lam Ta Kong watershed, Thailand. In this study, the Fuzzy Analytic Hierarchy Process (FAHP) method was applied to evaluate the risk of agricultural drought and the GIS technique was employed to give full consideration to the ambiguity and uncertainty of the agricultural drought risk. There are five risk factors to consider in the agricultural drought risk assessment and they are divided in a total of fifteen criteria: physical factors (slope gradient and elevation), climatic (rainfall and aridity index), soil (texture, drainage, fertility, erosion, and soil salinity), land utilization (land use and land cover) and water resources (precipitation days, stream density, distance from an irrigation canal, and groundwater volume). These criteria determine the weight and score used to evaluate their parental risk factors. The Analytic Hierarchy Process (AHP) was applied together with the triangular fuzzy numbers (TFNs) method to assess the data obtained from the criteria to achieve the drought risk assessment. The results indicated that the overall risk of the Lam Ta Kong area was at a moderate risk of agricultural drought (50.45%), of which 15.63% of the total area was at a high risk of agricultural drought. Moreover, 0.40% of the total area located at the central part of the watershed was at a very high risk which was due to its saline soil with > 50% dense salt crust. This research indicated that the major factors causing droughts in the watershed were related to the soil factors, especially soil texture, soil fertility and soil salinity. These soil factors were considered as the driving factors of drought. The results of this study can be used for land use planning and water resource management in order to prepare for droughts in the watershed.

Forest Fire Risk

Forest fires in the mid hills of Himachal Pradesh are mostly related to human activities. More than 90% of fires are originated from either deliberate or involuntary causes. The purpose of study is linked to identification of forest fire risk factors in 19 villages under Nauni and Oachhghat Panchayats. The methodology paradigm applied here is based on knowledge and fuzzy analytic hierarchy process (FAHP) techniques. Knowledge-based criteria involve socio-economic and biophysical themes for risk assessment. The risk factors are identified according to past occurrence of fire. Fuel type scores highest weight (0.3109) followed by aspect (0.2487), agricultural workers (0.1865), nutritional density (0.1244), population density (0.0622), elevation (0.0311), literacy rate (0.0207) and distance from road (0.0155) in descending order. In the study area applying FAHP, 24.96% of total area was classified under high-risk prone area, 21.69% area classified under high-risk, 34.63% area under moderate risk, while 18.61% area under low risk. The results were in accordance with actual fire occurrences in the past years.
