Vanishing Dimensions in Four Dimensional Cosmology with Nonminimal Derivative Coupling of Scalar Field

We discussed a mechanism that allows the universe to start from lower dimension ($d < 4$) in its very early era and evolves to four dimension at the end of the process. The mechanism is generated by a nonminimal derivative coupling of scalar field, where derivative terms of the scalar field coupled to curvature tensor. We solve the Einstein equations for a limit of large and nearly constant Hubble parameter and analyze the evolution of the Hubble parameter in this limit. The lower-dimensionality in early universe has advantages in the context of unification theory.Comment: 7 pages, 1 figur

THE EFFECT OF CHINA'S TAX REFORMATION ON ENTERPRISES

The Central People's Government Administration Council issued and announced “The decision on the harmonization of national tax administration "and" Implement Scheme of National Tax Administration” in 1950, which marked founding of tax system of China. Since 1994, China’s central government has started a reformation of this system and established the State Administration of Taxation, the State taxation bureau, as well as the local taxation bureau. Taxes have been adjusted to adapt to the business. After the reformation, government increases revenue, optimizes the fiscal structure, reduces expenditure, improves the local government’s enthusiasm and positivity in economy, ensures fiscal revenue growth and promotes the sustainable development of national economy. Throughout 35 years since the reform and opening policy, especially in the past several years, every reforms of tax system in China impact enterprises (main sources of tax revenue) deeply. How to optimize the current tax system to improve enterprises is an essential research area

The impacts of 5D-Building Information Modeling on construction's Time and cost performance

The construction sector is essential to a country's economic growth and development. This is why the construction of building projects is one of the most pressing concerns for the Indonesian government. The industrial sector has become increasingly dynamic and responsive to the challenges of building projects due to technological advancements. One example is the Building Information Modelling (BIM) 5D, an emerging technology integrating project implementation time and costs into a 3D model. Therefore, this study aims to investigate the success factors of BIM 5D implementation on the time and cost performance of high-rise building construction projects at Campus-II UIN Sunan Ampel Surabaya. This was achieved through a quantitative research method using a questionnaire completed by 62 respondents: the project manager, site manager, engineering head, and site engineer. Moreover, descriptive statistics were utilized to examine the frequency distribution of concentration measures and data distribution on sample characteristics and variables. The findings showed that the factors of tender document, human resources, BIM software, planning process and production process simultaneously positively affected the construction project's cost and time performance

Analisis Faktor Penyebab CCO dan Pengaruhnya Terhadap Biaya Kontraktor Pada Proyek Jalan Tol

This case study showed a 54% increase in Contract Change Order (CCO) work against the initial contract fee. The purpose of this study was to determine the factors that cause the occurrence of CCO, the influence of CCO on the contractor cost performance, and how much CCO affecting the contractor costs performance on toll road projects. The research method was using survey methods and data are processed with multiple linear regression. The results of this research shows that CCO work has the impact of increasing costs because of several factors such as contract documents, stakeholders, design, and construction. The most dominant variables that increase in costs were construction variables with a test value of 2,830, a significant value of 0.007, and a regression coefficient of 0.103. This research greatly influenced the performance of costs on toll road works by 80.9% of the remaining 19.1% described by other variables beyond the regression model analyzed

FAKTOR DOKUMEN KONTRAK DAN STAKEHOLDER TERHADAP BIAYA PROYEK PEMBANGUNAN JALAN TOL

Salah satu fenomena lain pekerjaan contract change order pembangunan jalan tol proyek strategis nasional (PSN) pada kenyataannya sering terjadi karena perencanaan sebelum pekerjaan dimulai tidak selalu berjalan dengan baik sesuai perencanaan awal. Tujuan penelitian untuk mengidentifikasi faktor penyebab timbulnya CCO, dampak CCO terhadap cost performance perusahaan jalan tol, dan sekaligus dampak pengerjaan CCO terhadap cost performance kontraktor pekerjaan jalan tol. Metode yang dilakukan dengan menggunakan metode survey kemudian data diolah dengan model regresi linier berganda. Karakteristik riset ini yaitu pembangunan jalan tol yang memiliki target dari pemerintah proyek strategis nasional (psn), menggunakan perkerasan beton lebih dominan, menggunakan jembatan slab on pile pada ruas jalan tol. Hasil riset diketahui bahwa pekerjaan cco memiliki dampak pada peningkatan biaya yang disebabkan oleh faktor dokumen kontrak dan faktor stakeholder. Variabel dominan yang mempengaruhi kenaikan biaya pembangunan jalan tol adalah dokumen kontrak dengan nilai uji-t 4,575, nilai signifikan  0,000, dan koefisien regresi 0,258. Pada saat yang sama, penelitian ini memiliki dampak yang kuat sebesar 62% terhadap kinerja biaya lokasi pembangunan jalan tol, dengan 38% sisanya diperoleh dari analisis regresi di luar model variabel

The Effect Of Customer Trust And Service Quality On Post Purchase Intention Through Customer Satisfaction On Online Grab Transportation (Survey Of Grab Customers In Purworejo)

This study aims to determine the effect of Customer Trust and Perceived Service on Post Purchase Intention through Customer Satisfaction in Grab Online Transportation (Survey of Grab users in Purworejo). Based on preliminary research by conducting interviews with 10 users of grab services in Purworejo. Their answers can be summarized as follows: (1) three out of 10 customers stated that they use Grab's services because the fares provided are very in line with what they expected, so they only use Grab as an online transportation service; (2) five out of 10 customers stated that they chose the grab service because they were satisfied with the services provided by Grab, so they only used Grab as an online transportation service; (3) two out of 10 customers stated that they feel comfortable with Grab and are willing to recommend Grab to the people around them and have the intention to use Grab in the future.The problem in this research is Post-Purchase Intention. Post-purchase (post-purchase) is a post- purchase evaluation that involves a number of concepts, including consumer expectations, satisfaction, doubts and feedback mechanisms. Satisfaction is an important emotion of this stage and is a determinant for future buying behavior (Loudon &Bitta, 1993). The object of this research is Grab customers in Purworejo. Sampling using the No Probability Sampling method. In this study, data from questionnaires were analyzed using descriptive quantitative methods. The hypothesis testing of this research was carried out with the help of SPSS Version 25 software. These values can be seen from the results of a significance of 5%.The object of this research is Grab users in Purworejo Regency. Sampling using the Non Probability Sampling method.
