In Asia alone, irrigated rice consumes as much as 150 billion m3 of water. With water being the most important component for rice production, yielding more rice with less water is therefore a formidable challenge. The aim of this study is to assess the water footprint of paddy plantation at Muda Rice Granary, Kedah for five consecutive years; 2012 to 2016. By using the life cycle assessment (LCA) approach, the potential environmental impacts due to water consumption in planting and processing rice will be assessed. By integrating water footprint with LCA may assist in analysing environmental impacts associated with direct and indirect water consumption throughout the whole process; starting from raw material extraction, processing or production, distribution, use, and disposal. The methodological framework follows the LCA framework; setting up goal and specifying the scope of study, followed by inventory analysis, water footprint sustainability assessment and finally interpretation or response formulation. The research boundary for this study include the growing phase of paddy; seedling and cultivating of the paddy until the rice milling process. By implementing this water footprint research in paddy field, it will be essential not only in research area but also in agricultural development in Malaysia. Consequently, it will become the baseline for other agricultural in Malaysia in this research area.","PeriodicalId":15706,"journal":{"name":"Journal of Energy and Safety Technology (JEST)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79622462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The keys of the system sizing are primarily to satisfy a specific load demand that depends on the power generated from the installed PV system and also to maintain hydrogen storage state of charge. A case study was conducted using Kuala Lumpur's meteorological data and a typical rural area load profile of 2.215 kWh. An economic analysis on the system was performed in order to determine system feasibility. The levelized cost of energy for the proposed system was RM1.98/kWh. However, the results showed that if the same configuration used absorbent glass mat (AGM) battery as the backup power supply, the system cost and levelized cost of energy is lower. Therefore, a sensitivity analysis of the electrolyzer and fuel cell efficiencies towards levelized cost of energy for the proposed system was executed. The result indicates that unless the efficiency of hydrogen storage technologies significantly increases in the future, the system will not be feasible to be implemented in Malaysia.","PeriodicalId":15706,"journal":{"name":"Journal of Energy and Safety Technology (JEST)","volume":"172 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76965140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human factor issues in the university laboratory were assessed according to four categories in HFACS: unsafe acts, precondition for unsafe acts, unsafe supervision, and organizational influences. The assessment showed that the student committed many errors due to precondition for unsafe acts, in particular no physical hazard evaluation required prior to conducting the experiment. Inadequate supervision in the university laboratory caused the presence of precondition for unsafe acts among students. The trajectory of human factor issues in the categories of unsafe acts, precondition for unsafe acts, and unsafe supervision pointed to the university’s organization. The human factor issues were analyzed according to three subcategories in organizational influences: resource management, organizational climate, and organizational process. The use of HFACS in the explosion in the Texas Tech University laboratory could demonstrate the sequence of failures and human factors leading to the accident.","PeriodicalId":15706,"journal":{"name":"Journal of Energy and Safety Technology (JEST)","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89191850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pyrolysis process was carried out from 25 to 700 °C under nitrogen atmosphere flowing at 150 ml/min via a thermogravimetric analyzer. The effect of biomass type was investigated on pyrolysis behavior. The particle size of biomass was in the range of 0.3 ≤ dp1 < 0.5 mm, whereas the heating rate was fixed at 80 °C/min. The thermogravimetric analysis (TGA) data were divided into three phases of degradation: moisture evolution, hemicellulose-cellulose degradation, and lignin degradation. The results showed that all biomass samples degraded between 25 and 170 °C in Phase I of moisture evolution. Among the biomass samples, coconut pulp achieved the highest mass loss (81.9%) in Phase II of hemicellulose-cellulose degradation. Lignin in all biomass samples gradually degraded from 450 to 700 °C in Phase III of lignin degradation. This study provides an important basis in understanding the intrinsic thermochemistry behind degradation reactions.","PeriodicalId":15706,"journal":{"name":"Journal of Energy and Safety Technology (JEST)","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84983023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accidents have resulted in various effects ranging from insignificant damages to very severe losses particularly on the environment and property. In order to avoid such accidents or reduce the risks of having one, it is vital to primarily understand the factors that could lead to marine transportation accidents involving HAZMAT. Surveys were conducted among 24 representatives from various shipping industries in Malaysia. The purpose was for the representatives to assign the appropriate ranking point for each factor based on their experiences and opinions on the significance of the factors in causing accidents. This information is valuable in serving as an initial screening for safety assessment in HAZMAT marine transport operation so that the potential hazards can be avoided or reduced. Based on the assessment results using the factors selected from the surveys, a more comprehensive assessment that is particularly relevant to enhance the existing safety assessment in HAZMAT operation can then be performed towards achieving an inherently safer HAZMAT marine transportation.","PeriodicalId":15706,"journal":{"name":"Journal of Energy and Safety Technology (JEST)","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82685244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
