Computer network technology is developing rapidly, and wired networks are being replaced by WiFi technology. The limitation of the WiFi coverage area is the main problem with this technology. Therefore, it is necessary to design for optimal placement of access points. This study analyzes the need for access point placement at KSOP Tanjung Mas Port, Semarang, where the need for internet connection via WiFi is very high. Simulation Annealing and Trilateration method is used in this study to determine the position of the access point. With the point blankspot method can be reduced.

This study aims to determine the effect of corporate social responsibility disclosure and good corporate governance on company value. This research was conducted on all companies listed on the Indonesia Stock Exchange for the 2017-2021 period. The method of determining the sample using non-probability sampling method with purposive sampling technique and obtained 170 observations. The data collection method uses non-participant observation. The data analysis technique used is Partial Least Squares-Structural Equation Model. The results of the study show that corporate social responsibility disclosure has no significant effect on company value and good corporate governance has a significant positive effect on company value which means that the higher the corporate social responsibility disclosure will not affect the stock value and with the implementation of good corporate governance, the higher of company value is reflected in the stock price as well. The implications of this research show the application of signal theory, stakeholder theory, and agency theory as well as providing benefits to parties who need it, especially companies and stakeholders related to companies in expressing corporate social responsibility disclosure and improving good corporate governance which can increase company value.

Incremental rotary encoder is a sensor that can be used to measure the degree of rotation in ship steering simulations. To create a ship steering simulation, Visual Basic software was used to simulate the movement of the rudder and ship. Meanwhile, to obtain incremental rotary encoder reading data, serial communication is used via Universal Serial Bus (USB) media bridged by Arduino which is programmed to convert incremental sensor signals into ASCII signals with a bolt rate of 9600 bps. The aim of this research is to test the accuracy level of the incremental rotary encoder sensor in ship steering simulations using Visual Basic software on commercial ships by using the Solas rule that a ship's rudder must comply when rotated from the midship position to the 35 degree port side position followed by the 35 degree position. starboard side and returning to midship, the rudder movement time was less than 28 seconds. Test results in terms of response speed of the incremental rotary encoder sensor are very good, while in terms of accuracy level for one degree of steering rotation, the result is 4.571 on the Arduino IDE serial monitor reading..

E-Government menawarkan pelayanan publik bisa di akses secara 24jam, kapan pun, dan dari mana pun pengguna berada. E-Government juga memungkinkan pelayanan publik tidak dilakukan secara face to face sehingga pelayanan menjadi lebih efesien. Menyadari akan besarnya manfaat E-Government, pemerintah Indonesia sejak tahun 2003 telah mengeluarkan kebijakan tentang penerapan E-Government dalam bentuk Instruksi Presiden Nomor 3 tahun 2003. Dengan menerapkan sistem online masyarakat akan dapat lebih menghemat biaya, dan waktu karena proses pembayaran pajak dilakukan secara online. Dimasa sekarang ini telah muncul teknologi berbasis aplikasi yang dapat dijalankan di Android dan IOS yang dinamakan SIGNAL. SIGNAL adalah Aplikasi Samsat Digital Nasional yang dapat memudahkan masyarakat Indonesia melakukan Pengesahan STNK Tahunan, Pembayaran Pajak Kendaran Bermotor (PKB) dan Sumbangan Wajib Dana Kecelakaan Lalu Lintas Jalan (SWDKLLJ) secara daring dengan terbitnya dokumen digital berupa E-Pengesahan (POLRI) , E-TBPKP (Bapenda Provinsi) dan E- KD (PT. Jasa Raharja). Metode yang akan digunakan adalah pendekatan penelitian kuantitatif menjelaskan bahwa metode kuantitatif merupakan metode penelitian yang berbasis pada filsafat positivisme, yang mana digunakan untuk meneliti populasi atau sampel tertentu, yang umumnya pengambilan sampelnya dilakukan secara random, dan data dikumpulkan menggunakan instrumen penelitian, lalu dianalisis secara kuantitatif/statistik dengan tujuan menguji hipotesis yang telah ditetapkan. Dan menggunakan teknik analisis statistik menggunakan SPSS 22 dan Ms.Excel.
