Place Attachment of Entrepreneurs: A Proposed Analytical Framework
Get PDFIn recent years, home-based enterprises have been giving significant implications for the economic improvement of the middle-low income community in Surabaya. With all of the limitations that exist, space, complex activities, and community acceptance become predictors that influence the formation of people-place relationship. Previous studies that tend to focus on the use of space are less concerned with the interaction undertaken by entrepreneurs which make them choose to continue their business where they have started. The dynamics of daily life in shaping social relations and functionality of place will affect how entrepreneurs perceive and assess their home-environment. Thus, it is important to highlight the process of the emerging attachment related to the use of a home for generating additional income. As the nature of place attachment which is multidisciplinary and socially constructed, this paper provides reviews on different paradigms, conceptualizations, and attachment types that should be used as analytical frameworks in the context of productive housing. A rich literature study aims to give further insight without ignoring the natural settings of the research context. By emphasizing the role of life experience of entrepreneurs, a more fruitful understanding towards accumulative assessment and perceived environment that triggers place attachment could be obtained in the future research
Development of Monitoring Tool to Support Lean Manufacturing Implementation
Get PDFLean is an approach that is carried out continuously to identify and eliminate waste or other activities that do not provide added value. Many companies have implemented lean concepts and got the benefits such as reduced cycle time, reduced operational costs, improved product quality, and other benefits. Although it provides many benefits, there are some weaknesses in implementing lean, one of which is due to the lack of monitoring. After the initial implementation, the process has never been reviewed and is rarely checked to ensure its implementation. Monitoring lean implementation requires tools that can help monitor work more efficiently. There are no specific tools that can be used to control and oversee lean implementation in the company. For this reason, this research will develop a tool for monitoring lean implementation. The tools to be developed adopting the logic of several methods, namely Quality Function Deployment (QFD), the framework of three matrix houses in lean implementation, and the House of Risk (HOR). This Lean monitoring tool is used to ensure that the corrective actions recommended for lean implementation are implemented. The Lean monitoring tool consists of three matrices that offer the ability to identify potential failures, the root causes of failures, and solutions to deal with lean implementation failuress

Mapping the Potential Liquefaction Area in Yogyakarta City Based on Ground Shear Strain Data
Get PDFThe appearance of liquefaction phenomena in some places in Yogyakarta city due to the 2006 earthquake indicates that the sediment in this area has a high potential to liquefy. Three main factors that caused liquefaction are ground shaking, lithological conditions, and groundwater depth. This study aims to investigate one of the three factors i.e ground shaking. For this purpose, the ground shear strain (GSS) data were analyzed for mapping the potential liquefaction area in Yogyakarta city. They were calculated from the seismic vulnerability index and PGA. The seismic vulnerability index was analyzed from a microtremor single station data recorded in 110 sites while PGA was calculated using a reference of the 2006 earthquake. The GSS value in the study area is at a range of 2.0 × 10−4 to 5.8 × 10−3 . In this range, the soils begin to be elastic-plastic so that they are susceptible to be fracture and settlement. The high GSS correlates with the location of the liquefaction due to the 2006 earthquake. The liquefaction potential map was obtained by comparing the GSS with liquefaction sites. The high liquefaction potential is located in the southern part of Yogyakarta city covering Mantrijeron, Mergangsan, Pakualaman, Umbulharjo, and Kotagede districts
A Structural Investigation of T’-Pr2-xCexCuO4 nanocrystals with x = 0.13
Get PDFThis report is briefly investigating the structural defect information of T’-Pr2-xCexCuO4 (T’-PCCO) nanocrystals with x = 0.13 at three different calcination temperatures. The as-synthesized powder of Pr2-xCexCuO4 (PCCO) nanocrystals with x = 0.13 were synthesized by using the chemically dissolved method within three different calcination temperatures, namely 900oC, 950oC, and 1000oC for 15 h in air. X-ray diffraction (XRD) technique is used to characterize the phase, structural, and crystalline defect information on the nanocrystal powder. It is found that all the indexed peaks are confirmed as PCCO phase with space group of I4/mmm and a minor impurity of Fm-3m space group. The lattice parameters are confirmed to be fluctuated signifying the stability of the Coulomb force at those temperatures. The post-Rietveld analysis using Bond Valance Sum (BVS) calculation shows the Ce-dependent of T’-PCCO nanocrystals while the Fourier difference suggests that the created crystalline defect as a part of the tetravalent doping effect which binds stronger apical oxygen. Moreover, at Pr- and Cu-site, the scattering distribution are fluctuating with the stable structure at 1000oC. This initial structural information is worth complementing the fundamental feature for understanding the T’-type cuprates
Penentuan Nilai Awal Iterasi pada Masalah Pendugaan Parameter Regresi Taklinier
Get PDFPaper ini membahas tentang pendugaan parameter model regresi tak linier menggunakan metode Newton, Gauss-Newton, steepest descent, dan metode homotopi. Metode-metode tersebut tidak senantiasa dapat memberikan hasil sebagaimana yang diharapkan, sebab hasil yang diperoleh sangat bergantung pada nilai awal yang diberikan. Keberhasilan metode-metode tersebut juga tidak ditentukan oleh seberapa dekat nilai awal terhadap solusi yang diharapkan, tetapi lebih kepada berhingga atau tidaknya elemen-eleman matrik Jacobi dari hampiran sistem persamaan tak liniernya. Selanjutnya, nilai awal diperoleh dengan cara membangkitkan bilangan random pada rentang tertentu dan dipilih yang dapat menghasilkan matriks Jacobi dengan elemen-elemen berhingg
Perbandingan Penyelesaian Integral Riemann, Lebesgue dan HK Berdasarkan Definisi
Get PDFSejak integral diperkenalkan oleh Newton dan Leibniz pada abad ke-17, alat ukur ini terus dilakukan kajian dan perumuman hingga saat ini. Terdapat tiga integral yang dikenal secara luas yaitu integral Riemann, integral Lebesgue dan integral HK. Pada masanya integral Riemann diterapkan untuk menyelesaikan berbagai persoalan tetapi kemudian diketahui memiliki keterbatasan. Integral Lebesgue muncul untuk mengatasi keterbatasan ini. Integral Lebesgue pun kemudian diketahui memiliki keterbatasannya tersendiri sehingga muncul integral Henstock-Kurzweil (integral HK) untuk mengatasi keterbatasan integral Lebesgue. Dalam banyak literatur seringkali untuk menyelesaikan soal integral tidak menggunakan definisi/ kerangka acuan yang sama sehingga sangat sulit memahami substansi maupun keterkaitan ketiga integral ini. Oleh karena itu, pada penelitian ini dilakukan perbandingan penyelesaian persoalan integral menggunakan definisi. Adapun dari empat persoalan integral yang dibahas, integral Riemann dapat menyelesaikan satu persoalan, integral Lebesgue dapat menyelesaikan dua persoalan dan integral HK dapat menyelesaikan seluruh persoalan yang dibahas
