How Structural and Environment Variables Affect Job Satisfaction of Hotel Employees in Surabaya

Abstract: This research focused on structural variables that could be controlled by the company and environment variables that could not be controlled by the company. These two variables could influence the creation of job satisfaction by hotel employees in Surabaya. This research was associative causal research using Structural Equation Modeling (SEM) as a statistical tool with SmartPLS 2.0 as the statistical software. This research used the non-probability method with convenience sampling technique with employees from four and five star hotels in Surabaya as the population. The total sample was 100 respondents. This research was conducted from November 2018 to January 2019. The results of this study show that structural variables have a positive and significant effect on job satisfaction. Meanwhile, environment variables have a negative and significant effect on job satisfaction.

Risk analysis on the development of a business continuity plan

Abstract: In the era of globalization increasingly advanced enterprise engaged in the sale of concrete iron will execute business processes by using software, hardware, networking, and others. Judging from the condition and the current reality of this company did not rule out the occurrence of the risk due to the problems in terms of data security, data integrity, hard disk damage, IT business continuity process. In this research conducted a risk analysis of the entire area of IT and business processes within the company. As for the area to be analyzed by means of analyzing the business continuity that is based on the Standard ISO 27002: 2005 chapter 14, and analyze IT Domain and perform risk assessment and risk mitigation. The risks are found is their dependence on outsourced programmers who acts as a consultant, so rarely do risk assessment in IT companies, the unavailability of a Disaster Recovery Plan and IT Security Plan, an evaluation of the permissions are less common, and no one specifically designated for IT management, lack of training or, and the absence of a standard or framework. The results of this risk analysis can help companies recognize and avoid the risks of what might happen and can avoid the danger of business continuity, so that the company can take action to prevent or deal with the risks that would happen.

Implementation of Fuzzy Logic in FPGA for Maze Tracking of a Mobile Robot Based on Ultrasonic Distance Measurement

Abstract: This paper describes an application of fuzzy logic to solve the problem of an autonomous mobile robot in tracking the path within a maze. The robot equipped with ultrasonic transceivers to measure the distance between robot and the wall. The information of distance then will be processed using fuzzy-based algorithm and implemented in two chips FPGA. The FPGA has responsibility to formulize the rule of the fuzzy and generate the PWM signals for robot’s motors as the result of fuzzy inference. Implementing all necessary fuzzy logic algorithms will require many FPGA resources. Therefore, we use two FPGAs: XC4010E and XC4005XL. The first one for the fuzzification and rule base evaluation, and it consumes 98% of its resources (CLBs). The second one for defuzzification and PWM output generation, which utilizes 78% of all its CLBs. By implementing fuzzy logic using FPGA, the robot achieves relatively safe tracking the path in real-time sense. Abstract in Bahasa Indonesia: Dalam paper ini dijelaskan aplikasi logika fuzzy pada robot bergerak untuk mencari jalan keluar dalam sebuah labirin. Robot dilengkapi dengan pemancar dan penerima ultrasonic sebagai pengukur jarak antara robot dengan dinding labirin. Informasi berupa jarak tersebut kemudian diproses menggunakan algoritma fuzzy yang diimplementasikan dalam dua buah FPGA. FPGA bertanggungjawab dalam memformulasikan aturan dari logika fuzzy yang digunakan dan membangkitkan sinyal-sinyal PWM untuk mengendalikan motor robot sebagai hasil dari proses inferensi. Untuk mengimplementasikan semua fungsi-fungsi logika fuzzy, dibutuhkan banyak sekali sumber daya FPGA. Karenanya kami menggunakan dua buah FPGA: XC4010E dan XC4005XL. Komponen FPGA yang pertama, yakni XC4010E, digunakan secara khusus untuk proses fuzzification dan menggunakan 98% dari sumber daya FPGA yang berupa CLB. Komponen FPGA yang kedua, yakni XC4005XL, digunakan untuk proses defuzzification serta pembangkitan sinyal PWM, dan menggunakan 78% dari total CLB yang tersedia. Dengan mengimplementasikan logika fuzzy menggunakan FPGA, robot dapat menelusuri jalur labirin secara real-time dengan lebih aman.

Exploring the Impact of Brand Equity, Corporate Reputation, and Product Quality on Customer Loyalty toward a National Newspaper in Surabaya

Abstract: National and local newspaper competes for gaining more market share. It is also happened with XYZ newspaper. XYZ newspaper as the biggest national newspaper in Indonesia tends to have low market share in other area outside Jakarta, especially in Surabaya. Previous researches showed that brand equity, corporate reputation, and product quality are able to influence customer loyalty which can lead to increasing number ofcustomer and market share. Therefore, this research is conducted to examine the influence of brand equity, corporate reputation, and product quality on customer loyalty toward XYZ newspaper in Surabaya. Quantitative method is used and multiple regression is chosen as the analytical method. With 95 samples collected through simple random sampling method, the result of the research shows that brand equity, corporate reputation, and product quality simultaneously have significant influence on customer loyalty toward XYZ newspaper in Surabaya. Also, corporate reputation and product quality individually have significant influence on customer loyalty toward XYZ newspaper in Surabaya. But, brand equity as individual has no significant influence on customer loyalty toward XYZ newspaper in Surabaya. Based on this fact, author concludes that XYZ newspaper should focus on improving corporate reputation and product quality, while also enhances its brand equity in order to increase the customer loyalty.

Aplikasi e-tailing penjualan handphone online pada toko peace cell

Abstract: Dengan makin ketatnya persaingan bisnis, maka tiap badan usaha dituntut untuk dapat memberikan pelayanan sebaik mungkin terhadap customernya serta dapat memperluas daerah pemasaran untuk menghadapi persaingan yang ada. Salah satu cara yang tepat adalah dengan memanfaatkan teknologi informasi yaitu melalui website E-Commerce. Untuk mengimplementasikan sistem, pertama-tama dilakukan analisa sistem penjualan yang ada saat ini. Dari hasil analisa yang dilakukan dapat diketahui bahwa sistem yang dibutuhkan adalah suatu sistem yang dapat melakukan penjualan secara online, memberikan informasi mengenai handphone yang dijual secara lengkap, dan mengelola data produk. Sistem dirancang dan dibangun dengan menggunakan teknologi PHP, Apache sebagai web server, dan MySQL sebagai database server. Berdasarkan dari pengujian dengan metode kuisioner terhadap pengguna terhadap fasilitas-fasilitas yang tersedia untuk member dan administrator, fasilitas pembayaran, serta sistem laporan, didapatkan hasil kuisioner evaluasi pengujian sistem oleh member sebesar 85,42 % dan administrator sebesar 81,25 % maka disimpulkan bahwa sistem website berjalan sesuai yang diinginkan.
