Analisis Waktu Baku dan Kapasistas Produksi dalam Proses Pembuatan Mesin Perontok Jagung di CV. Citra Dragon

This study aims to calculate the standard time to produce the right time in producing corn thresher machine, so that the production capacity in one month is obtained at CV. Citra Dragon. Observations was made in the manufacture of corn threshing machine. Working time data was collected using stopwactch time study and adjustment method used was Westinghouse. The research method use was to analyze the work done by operators in the manufacture of corn thresher machine, and calculate the operator’s working time per work element. The result showed that the standard time needed in the process of making 1 unit of corn thresher machine is 78.603 second (21 hours) and the production capacity per month is 7 units of corn thresher machine.

Ontology of a Wavefunction from the Perspective of an Invariant Proper Time

All the arguments of a wavefunction are defined at the same instant, implying the notion of simultaneity. In a somewhat related matter, certain phenomena in quantum mechanics seem to have non-local causal relations. Both concepts contradict the special relativity. We propose defining the wavefunction with respect to the invariant proper time of special relativity instead of the standard time. Moreover, we shall adopt the original idea of Schrodinger, suggesting that the wavefunction represents an ontological cloud-like object that we shall call “individual fabric” that has a finite density amplitude vanishing at infinity. Consequently, the action of measurement can be assimilated to the introduction of a confining potential that triggers an inherent nonlocal mechanism within the individual fabric. This mechanism is formalised by multiplying the wavefunction with a localising Gaussian, as in the GRW theory, but in a deterministic manner.

CONTRIBUTION OF MOTION STUDY TO STANDARD TIME AT BALL TEA STATION (CASE STUDY PT. MITRA KERINCI, SOUTH SOLOK)

PT Mitra Kerinci is a company established in West Sumatra Province which is engaged in tea plantations and tea processing in its factories. PT Mitra Kerinci produces an average of 7,000 kg or 7 tons of green tea shoots per day. The production process for processing tea shoots, the factory sometimes does not reach the production target in accordance with the production target of the company. The goal of research to determine the amount of the contribution of the motion study to the standard time and determine the amount of the contribution of the standard time to the increase in productivity in the final drying process at Ball Tea station, the production of tea shoots at PT. Kerinci Partners. This research an experimental research type and uses the same subject research design (treatment by subject design), namely the treatment is imposed on the same subject. The results of time calculations after the motion study on the process flow map reached 15,676.02 seconds. Then proceed with the calculation of the cycle time which reaches 825.41 seconds with the actual standard deviation obtained at 3.58 and the standard deviation of the subgroup distribution is 1.79. After knowing the results of the average cycle time, the actual standard deviation and the standard deviation of the subgroup distribution, the data uniformity test was continued, starting with calculating the BKA and BKB. The BKA calculation results obtained 830.78 and the BKB reached 820.04. So that in the data uniformity test the results reached 0.908. In the series of movements of the left and right hands after the repair, a cycle time of 825.41 seconds / unit of Ball Tea was obtained from the previous time, reaching 906.66 units / Ball Tea and getting a time difference of 81.25 seconds. In the calculation of the standard time, the normal time calculation is carried out first, after it is known that the result of the adjustment calculation reaches 1.12 so that the normal time is obtained with a total of 924.45 seconds. Continue to calculate the standard time and the results reach 1423.65 seconds with an allowance of 54%. This contributed to an increase in productivity by 5.7%.

EP.FRI.1036 Provision of 7 Day Radiology Service: Are we compliant against standards

Aim The audit aimed to retrospectively look into reporting times for investigations for acute surgical inpatients and determine if we were able to meet standards as set in NHS 7 day service provision standards which aims to provide 7day radiological service for hospital inpatients from commission to reporting. Method A prospective audit is undertaken to collect waiting times for investigations for all acute admissions requiring radiological investigations over one month. Investigations were categorized into ‘critical’, ‘urgent’ and ‘non-urgent’ according to guidelines set by Royal College of Surgeons. The results were tabulated in Excel and analyzed to determine level of compliance. Results Collected data shows that off the total 119 investigations performed, 34% were USG, 63% were CT scans and 2.5% were MRI. Standards were met for a total of 67% of the investigations. Only 20% of critical, 67% of urgent and 76% of non-urgent scans were done within the standard time while by modality, CT scans had the highest rate of compliance. 60% of investigations requested over weekends met standards with highest compliance for USG and for non-urgent scans. Average reporting time was approximately 50 minutes. Conclusion The audit outcome highlighted that 1 out of 3 investigations did not meet standards. Within its limitations of no numerical parameters to guide urgency, the audit was able give an idea of the radiology service offered by the hospital and highlighted clear areas for improvements which can be suggested to improve compliance such as documenting ‘operative catergory’ of requested investigations on request forms.

Tidal deformation of quantum black holes

The response of a gravitating object to an external tidal field is encoded in its Love numbers, which identically vanish for classical black holes (BHs). Here we show, using standard time-independent quantum perturbation theory, that for a quantum BH, generically, the Love numbers are nonvanishing and negative. We calculate the quadrupolar electric quantum Love number of slowly rotating BHs and show that it depends most strongly on the first excited level of the quantum BH. Finally, we discuss the detectability of the quadrupolar quantum Love number in future precision gravitational-wave observations and show that, under favourable circumstances, its magnitude is large enough to imprint an observable signature on the gravitational waves emitted during the inspiral. Phase of two moderately spinning BHs.
