From the destination research this obtained results analysis in a manner economical cost acceleration (crashing) with working hours more shift economical with total costs project as big as Rp. 13,881,934,901.31 and for optimal duration time project the fastest that is with acceleration (crashing) additional working hours (overtime) 3 hours with duration time project finished for 154 days or 56% more fast from normal duration is 350 days
STUDI KOMPARASI METODE EOQ DAN POQ DALAM EFISIENSI BIAYA PERSEDIAAN MATERIAL PAVING BLOCK
No full textConstruction materials project is one of the businesses in the construction project to provide building materials in setting up a building. Rapid increasing development causing many businesses engaged in the field of construction materials. In its activities, the company is in dire need of accurate, relevant and efficient information. Information is not only needed for decision-making, but also for planning and controlling. One of the most important information is inventory information. Inventory information will determine the survival of the company due to lack of inventory. Therefore, the company needs inventory control calculation, or excess inventory will have direct impact on the survival of the company. This paper has objective of sand material analysis for paving block production. Inventory control and material measures that will be used to analyze are Economic Order Quantity (EOQ) and Period Order Quantity (POQ). The case study in this research is in the company of the paving block Merapi Volcanic Materials Innovation Centre - Islamic University of Indonesia (PIMVM - UII). Object of this research is on the sand material inventory. The data to be processed is the data of volume requirements, the cost of ordering, purchasing and storing of sand material. The data will be processed using the method Inventory Control EOQ and POQ. The result of this research showed the cost of EOQ is Rp. 22.505.098,-, and the cost of POQ is Rp. 44,577,478,-. From the results of these two methods, the difference in the price of sand on the EOQ is 49.5% less expensive than the POQ. It is because the cost of storage on the POQ greater than EOQ so the costs for materials become more expensive. Thus, the optimal inventory control methods in the production of paving blocks PIMVM-UII is EOQ
EVALUASI BIAYA DAN WAKTU PADA PROYEK PENGGANTIAN JEMBATAN DENGAN MENGGUNAKAN METODE KONSEP NILAI HASIL
No full textOn the implementation of project, there could have been problem in performance of time and cost that caused project that had been completed not to go according to plan. Therefore, performance evaluation is needed so that project can be carried out as planned and can also evaluate of project performance. In this research, time and cost performance will be evaluate using the earned value concept method in the Project for Replacement of the Nanga Tepuai-Nanga Semangut Section Bridge. Earned Value Concept can provide information about progress position of project time and cost performance in a certain period of time. The stages of this research begin with data collection of S-Curves, RAB, Weekly Progress Report and Financial Report. Next, determine three indicators, that is BCWS, BCWP and ACWP, which is then used to analyze the Schedule Variance, Schedule Performance Index, Cost Variance, Cost Performance Index, Estimation at Schedule, and Estimation at Completion. The result of this research showed, from time performance, in month-1 until month-6, value of SV is postitive and the value of SPI is more than 1, which means that the project is implemented faster than plan, and in month-7 the value of SV is 0 and the value of SPI is 1, which means that the project is implemented according to the plan. About cost performance, in month-1 the value of CV is negative and the value of CPI is less than 1, which means the costs incurred for implementating more than the plan, and in month-2 until month-7 the value CV is positive and the value of CPI is more than 1, which means the costs incurred for implementating less than the plan. The best EAS value is obtained in reporting month-2, it’s 3,63 months. The best EAC value is obtained in reporting month-4, it’s Rp. 7.239.951.844,01
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
