Loading And Unloading

Indonesia as one of the biggest archipelagic countries, sees the potential for the need for ports as an inter-island logistics sector. Ports in Indonesia are managed by PT. Indonesian Port, one of the branches of PT. Pelindo is PT. X which has liquid bulk stores specifically for CPO loading and unloading. The problem that occurs is the increase in loading and unloading service time that has exceeded the set resting time, which results in the length of the waiting time for the ship in the pool. So that it will have an impact on the quality of CPO, which causes an increase in the levels of free fatty acids in CPO. Because it is proposed to improve the process of loading and unloading CPO services to minimize queues and reduce ship waiting times. Simulation is completed with ExtandSim software. As for the selected scenario, namely the second alternative scenario showing an increase in service on each pier, the average ship input is 64 ships and the average output is 62 ships, more optimal than conceptual conditions, the proposed calculation of investment costs is the addition of a pipeline of 104,244.00 US $.Keywords:  Extendsim, Port Of Liquid Bulk, CPO, Descrette Event Simulation

Whole inshore male capelin (Mallotus villosus) were stored at −23 °C for 2 mo (C2), or 6 mo (C6) prior to thawing, beheading and eviscerating, and refreezing. Though the quality of the twice-frozen product was in both cases inferior to a once-frozen sample, it was still quite acceptable after 2 yr of refrozen storage. As expected, quality was superior in the C2 samples, but in both sets of samples taste deteriorated to a greater extent than texture. Chemical measurement of peroxide value indicated a possible development of rancidity that could not be detected by sensory analysis. Considerable lipid hydrolysis occurred, with the free fatty acids (FFA) at least doubling during storage; increases were greater in C6. In both experiments FFA production correlated with texture, taste, and with extractable protein nitrogen (EPN). Dimethylamine (DMA), trimethylamine (TMA), hypoxanthine, and EPN appeared to be good indicators of storage time and sensory quality. Key words: capelin, dimethylamine (DMA), extractable protein nitrogen (EPN), free fatty acids (FFA), hypoxanthine, peroxide value, refrozen storage, taste, texture, trimethylamine

BackgroundBreathlessness, a common symptom in advanced disease, is a distressing, complex symptom that can profoundly affect the quality of one’s life. Evidence suggests that specialist palliative care breathlessness intervention services can improve physical well-being, personal coping strategies and quality of life. In the UK, the use of quality improvement methods is well documented in the National Health Service. However, within the independent hospice sector there is a lack of published evidence of using such methods to improve service provision.AimThe aim of this project was to reduce the waiting time from referral to service commencement for a hospice breathlessness service by 40%—from a median of 19.5 to 11.5 working days.MethodsUsing a quality planning and systems thinking approach staff identified barriers and blockages in the current system and undertook plan-do-study-act cycles to test change ideas. The ideas tested included offering home visits to patients on long-term oxygen, using weekly team ‘huddles’, streamlining the internal referral process and reallocating staff resources.ResultsUsing quality improvement methods enabled staff to proactively engage in positive changes to improve the service provided to people living with chronic breathlessness. Offering alternatives to morning appointments; using staff time more efficiently and introducing accurate data collection enabled staff to monitor waiting times in real time. The reduction achieved in the median waiting time from referral to service commencement exceeded the project aim.ConclusionsThis project demonstrates that quality improvement methodologies can be successfully used in a hospice setting to improve waiting times and meet the specific needs of people receiving specialist palliative care.

Major Consideration

Nitrogen and sulphur, both vital structural elements, are especially needed for the synthesis of proteins and oils. Investigations revealed the required application of sulphur is one half to one third the amount of nitrogen, and the ratio becomes narrower in mustard (Brassica juncea L.), followed by wheat and rice. The efficiency of an increased level of nitrogen required a proportionately higher amount of sulphur. A critical investigation on the effective utilization of applied vis-à-vis absorbed nitrogen in wheat and mustard envisaged accumulation of NO3-N in vegetative parts when sulphur remained proportionately low. Application of sulphur hastened the chemical reduction of absorbed NO3–for its effective utilization. The effect was more pronounced in mustard than in wheat. Easily available forms of sulphur, like ammonium sulphate and gypsum, as compared to pyrite or elemental sulphur, maintained adequate N to S ratio in rice, resulting in a reduction in the percent of unfilled grain, a major consideration in rice yield. A narrow N to S ratio, with both at higher levels, increased the oil content but raised the saponification value of the oil, a measure of free fatty acids. Whereas, a proportionately narrow N to S ratio at moderate dose resulted in adequately higher seed and oil yield with relatively low saponification value, associated with increased iodine value of the oil, indicating respectively low free fatty acids and higher proportion of unsaturated fatty acids, an index for better quality of the oil.

Trawler-caught cod were frozen before and after rigor mortis in brine (23% NaCI) and between refrigerated plates, thawed in circulating water at 7 C or in a conveyorized microwave oven, then processed into fillets which were packaged, plate-frozen, and stored at −18 C.All samples thawed satisfactorily in circulating water. Some overheating was encountered during thawing in microwaves. But the equipment was not developed sufficiently to permit assessment of the commercial potential of microwave thawing.Examinations of the fillets from the thawed fish for appearance, odor, and texture showed that freezing pre-rigor is preferable to freezing post-rigor and that thawing by means of microwaves is preferable to thawing by means of water. Freezing or thawing methods did not affect the pH of the thawed fillets.Results of organoleptic and chemical tests to determine the changes in quality of the refrozen fillets packaged and stored at −18 C for 12 months indicated that neither the average taste panel scores nor the chemical tests for moisture, total lipid, free fatty acids, and extractable protein nitrogen showed any difference attributable to state of rigor, freezing method, or thawing method. The taste panel slightly preferred the texture of fillets from fish frozen pre-rigor and from fish frozen in brine. Free fatty acids increased sharply as a result of thawing and refreezing, and the rapid increase continued during the first 2 months of frozen storage. Taste panel scores correlated significantly with free fatty acids (1% level) and with extractable protein (5% level).

The need of energy never comes to an end so; the challenge is to procure power source sufficient to offer for our energy needs. Besides, this energy source must be dependable, renewable, recurring and non-contributing to climate change. Aims: This study was aimed to produce biodiesel from Roselle seed oil and to investigate its quality.  Methodology: The Roselle seeds were clean from dirt, milled to proper size and the oil was extracted using soxhlet with n-hexane as solvent. The extracted oil was subjected to physiochemical analysis tests and then transesterified using methanol and potassium hydroxide as catalyst; with ratio of oil to alcohol 1:8 at 65°C. The quality of produced biodiesel was investigated and compared to international standards. The fatty acid composition of the produced biodiesel was determined by GC-MS. Results: Based on the experimental results, the yellow with characteristic odor oil was obtained from the seeds had the following physicochemical properties: yield, 12.65%; refractive index (25°C), 1.467 m ; free fatty acids, 5.5%; saponification value, 252 mg KOH/g of oil; density, 0.915 g/mL and ester value, 241 mgKOH/g. Also the biodiesel yield achieved was 96%, with density, 0.80 g/mL; API, 44.63; Kinematics viscosity @ 40˚C, 0.742; Pour point, < -51˚C; and Micro Carbon Residual (MCR), 0.65%; which conformed to the range of ASTM D6751 and EN 14214 standard specifications. However, the GC-MS analysis result revealed that the biodiesel produced was methyl ester and free other undesired products such as linoleic acid (33%), elaidic acid (29%) and palmitic acid (17%) and other biomolecules. Conclusion: Based on the obtained results, Roselle seed oil had potential for biodiesel production due to its high contains of free fatty acids. Therefore, in the future, more investigations in alcohol: oil ratio and the concentration of catalyst may be warranted to increase the yield much more.

Quality is the overall characteristics and characteristics of a product or service whose ability to satisfy needs, both expressed and implied (Irwan & Haryono, 2015). In this era of increasingly competitive industrialization, every business person who wants to win the competition in the industrial world will pay full attention to quality. QCC is a new concept to improve the quality and productivity of industrial/service work. It is evident that one of the success factors of industrialization in Japan is the effective implementation of QCC. In this research journal, the quality of crude palm oil (CPO) levels is decreasing. There are 3 types of defects, namely levels of FFA (Free Fatty Acids), levels of Moisture (Water) and levels of Dirt (Stool). Of these three, the most dominant are FFA levels and Moisture levels. Free fatty acid content (FFA) of 158 samples tested contained 150 samples of free fatty acids (FFA) which were outside the company standard. Then followed by moisture content with a total defect of 45 samples from 158 test samples. At the level of dirt (Dirt) there are absolutely no samples that are outside the company's standards.

The Subject

Emergency departments (ED) are responsible for the immediate care and stabilization of patients in critical health conditions. Several factors have caused overcrowding in the emergency care system, but the variability of patient arrival and the triage process requires special attention. The criticality of these components and their configuration directly impact the waiting times, length of stay and quality of service, being the subject of several studies. So, this paper aims to understand by means of Discrete Event Simulation how ED works with the variation of patient arrival and how this variation highlights the bottlenecks of the triage process. Varying the patient arriving interval between 0.1 and 7.6 in a 4-hour scenario,  the system saturation point was established in β = 1.1. Besides, with the variation in the number of triages points, a considerable decrease in the total length of stay spent and the waiting times were noticed, mainly when there was two triage points operating simultaneously.

Study on the purification and quality test of used cooking oil with turmeric has been done. This study aims to determine the quality of cooking oil after purified turmeric. The quality parameters of oil studied were the moisture content, free fatty acids (FFA), and peroxide. The methods used for determination of these parameters were gravimetry for moisture content, acid-base titration for free fatty acids, and iodometric for peroxide. The test results for water from 0.6% to 0.4% free fatty acid from 1.2% to 0.2%, and peroxide levels before and after purification were successively from and 6 meq/g to 4 meq/g, respectively. Only free fatty acids of all three parameters met the requirement of SNI.

ObjectivesWe assessed: (1) waiting time variation among surgeons; (2) proportion of patients receiving surgery within benchmark and (3) influence of the Winnipeg Central Intake Service (WCIS) across five dimensions of quality: accessibility, acceptability, appropriateness, effectiveness, safety.DesignPreimplementation/postimplementation cross-sectional design comparing historical (n=2282) and prospective (n=2397) cohorts.SettingRegional, provincial health authority.ParticipantsPatients awaiting total joint replacement of the hip or knee.InterventionsThe WCIS is a single-entry model (SEM) to improve access to total hip replacement (THR) or total knee replacement (TKR) surgery, implemented to minimise variation in total waiting time (TW) across orthopaedic surgeons and increase the proportion of surgeries within 26 weeks (benchmark). Impact of SEMs on quality of care is poorly understood.Primary and secondary outcome measuresPrimary outcomes related to ‘accessibility’: waiting time variation across surgeons, waiting times (Waiting Time 2 (WT2)=decision to treat until surgery and TW=total waiting time) and surgeries within benchmark. Analysis included descriptive statistics, group comparisons and clustered regression.ResultsVariability in TW among surgeons was reduced by 3.7 (hip) and 4.3 (knee) weeks. Mean waiting was reduced for TKR (WT2/TW); TKR within benchmark increased by 5.9%. Accessibility and safety were the only quality dimensions that changed (post-WCIS THR and TKR). Shorter WT2 was associated with post-WCIS (knee), worse Oxford score (hip and knee) and having medical comorbidities (hip). Meeting benchmark was associated with post-WCIS (knee), lower Body Mass Index (BMI) (hip) and worse Oxford score (hip and knee).ConclusionsThe WCIS reduced variability across surgeon waiting times, with modest reductions in overall waits for surgery. There was improvement in some, but not all, dimensions of quality.
