Analisis Model Transformasi Hujan-Aliran pada DAS Kali Lamong dengan HECHMS
Get PDFHujan dan aliran merupakan sebuah fenomena alam yang berkaitan dimana hujan merupakan salah satu penyebab terjadinya aliran air dipermukaan tanah. Dalam proses terjadinya hujan menjadi aliran terdapat banyak parameter yang berpengaruh seperti tinggi curah hujan, karakteristik tanah dan tutupan lahan. Lokasi yang dipilih adalah DAS Kali Lamong dikarenakan pada DAS Kali Lamong memiliki potensi air yang belum termanfaatkan dan juga waktu musim penghujan sering terjadi banjir. Untuk mengetahui besar pengaruh dari parameter yang berpengaruh maka dibuat model hujan-aliran. Dalam pembuatan model hujan-aliran metode yang digunakan adalah SCS curve number dengan program bantu HEC-HMS. Setelah dilakukan pemodelan hujan-aliran hasil dari simulasi akan dibandingkan dengan debit observasi yang tersedia pada AWLR Boboh untuk mengetahui keandalan dari model yang telah dibuat. Berdasarkan hasil pemodelan data hujan tahun 2011 didapatkan nilai NSE 0.5961 dengan debit maksimum 223.9 m3/s yang terjadi pada tanggal 25 Maret 2011
Evaluating the CDMA System Using Hidden Markov and Semi Hidden Markov Models
Get PDFCDMA is an important and basic part of today’s communications technologies. This technology can be analyzed efficiently by reducing the time, computation burden, and cost by characterizing the physical layer with a Markov Model. Waveform level simulation is generally used for simulating different parts of a digital communication system. In this paper, we introduce two different mathematical methods to model digital communication channels. Hidden Markov and Semi Hidden Markov models’ applications have been investigated for evaluating the DS-CDMA link performance with different parameters. Hidden Markov Models have been a powerful mathematical tool that can be applied as models of discrete-time series in many fields successfully. A semi-hidden Markov model as a stochastic process is a modification of hidden Markov models with states that are no longer unobservable and less hidden. A principal characteristic of this mathematical model is statistical inertia, which admits the generation, and analysis of observation symbol contains frequent runs. The SHMMs cause a substantial reduction in the model parameter set. Therefore in most cases, these models are computationally more efficient models compared to HMMs. After 30 iterations for different Number of Interferers, all parameters have been estimated as the likelihood become constant by the Baum Welch algorithm. It has been demonstrated that by employing these two models for different Numbers of Interferers and Number of symbols, Error sequences can be generated, which are statistically the same as the sequences derived from the CDMA simulation. An excellent match confirms both models’ reliability to those of the underlying CDMA-based physical layer

Get PDFSMEs or small and medium enterprises currently have a very important position not only in employment, and the welfare of the community in the region, in many cases SMEs can stabilize the problem of social inequality. Therefore, SMEs are required to have good performance. There is a basic theory about financial literacy theory that argues that the behavior of people with a high level of financial literacy might depend on the prevalence of the two thinking styles according to dual-process theories: intuition and cognition. This study aims to examine the influence of financial literacy, entrepreneur’s motivation, industrial environment, and competitive strategy on the performance of small and medium enterprises. By classifying the result of previous research, this research found some propositions: (1) financial literacy has a significant effect on the performance of SMEs (2) entrepreneur’s motivation significantly influences the performance of SMEs (3) industrial environment significantly influences the competitive strategy (4) competitive strategies significantly influence SME performance (5) industrial environment significantly influences the performance of SMEs. This study using Partial Least Square (PLS) technique to analyze the data. The proposition as the result studies can be investigated empiricall

By the classifying the result found some propositions: 1) The good of environmental performance affect positive financial performance, 2) The higher disclosure of Corporate Social Responsibility affects the financial performance to be good, 3) The good implementation of Good Corporate Governance can make the financial performance to be good and, 4) The good ratio of Leverage will affect positively the financial performanc
Formulating Method to Improve Web Quality: Integrating Fuzzy Logic, Web Quality, and Refined Kano
Get PDFDisruption of technology requires businesses to perform digital transformation in its product marketing, one of which includes owning an e-commerce website. By having an e-commerce website, businesses get detailed consumer behavior patterns from their visits. This pattern of behavior can be utilized for future business process development. The importance of the existence of this e-commerce website requires businesses to be able to provide the best service when consumers access the website. In this research, the appropriate methods are formulated for businesses to improve the quality of their e-commerce services. In previous studies, Web Quality and Refined Kano methods are often used to improve the quality of e-commerce services. Although the two methods are often integrated to find more accurate recommendations, the recommendations produced are still subjective and have a high level of ambiguity. To reduce the level of subjectivity and ambiguity, it is necessary to integrate fuzzy logic into Web Quality and Refined Kano. The integration of fuzzy, Web Quality, and Refined Kano methods is expected to provide the most accurate and objective recommendations for businesses to improve the quality of their e-commerce services
