Abstract

The room temperature depends on the intensity of light. Low light intensity is not proper for the room because it causes bacteria or fungus on the room’s walls. We create a telemonitoring system and air quality control in semi-indoor rooms using wireless sensors as a support system. It can provide real-time information to the user on the screen display. In this study, we use a wireless sensor as monitoring, VEML6070, DHT11, and BH1750 as sensors to determine the air quality in the semi-indoor room. Data will be sent from Arduino Uno to a server through raspberry pi 3 and NRF24L01. Client-server communication techniques are designed for communication between the node and the server, so the data transmission errors can be pressed. The display of the work system will be monitored using a display in the android application. From the experimental results, the system between the node and the server runs well. The experimental results obtained varying Delay with an average delay of 0.318 seconds when there is no change in conditions on the fan and UV lamp. The average Delay is 0.491 seconds when there is a change in conditions on the fan and UV light

Abstract

According to the World Health Organization (WHO), an elderly person is someone who has entered the age of 60 years and over. Based on recorded data from Radio Suara Surabaya from January 2017 to July 2019, Radio Suara Surabaya has received 618 listener reports of missing people due to dementia or senility. This research aims to provide an alternative in order to keep an eye on the presence of the elderly by utilizing the U-Blox Neo 6m GPS module and the ESP8266 NodeMCU microcontroller. In addition, supervisors can use an android application to implement geofence technology. The results of the research conducted gave the results by testing the GPS U-Blox Neo 6m module placed in different locations and conditions resulting in receiving information signals obtained from 3-9 information satellites that send signals. The distance difference test was carried out at 10 different location points resulting in a difference in the distance from 1 m to 8 m. In addition, there is data transmission delay testing carried out at different times of the morning, afternoon, and night which results in delays ranging from 0.2 seconds to 1 second. Based on the research conducted, it can be concluded that the implementation of geofence results in a geofence application that can apply geofence to the elderly by depicting a circle radius of 100 m based on the center point of a specified location. The use of GPS U-Blox Neo 6m gives results by calculating the average distance difference of 3.7m.

Abstract

A Server is a system that provides certain services on a computer network. The Server has its own operating system called the network operating system. The Server also controls all access to existing networks.  In order to help server tasks, a server mirroring system is set up where the server is duplicating a data sets or an exact clone of a server providing various information. Mirror server or also called Server synchronization is a duplicate of a server. To add performance from the server, a load balancer is required. Load balancing is a technique for distributing two internet connection paths equally. With the application of load balancing the traffic will run more optimally, maximizing throughput, and avoiding overload on the connection path. Iptables is used for IP filtering so the clients could access the server according to the closest server zone, so that the load balance combined with iptables can reduce the server's load. A common problem is when many clients access a server and the server will overload and cause the server performance to be slow because of the heavy traffic. The access Client also get the effect of this, which is slow response time. From the result of research on the combination of load balance and iptables, it was found that the load balance with the round robin algorithm the average delay obtained for server1 was 0.149 seconds and 0.19122. Server2 has an average delay of 0.161 seconds and 0.012 seconds.

Abstract

The growing number of internet applications and their users can affect the quality of the internet, each application has different traffic needs. In addition, bandwidth management can also lend bandwidth that has been allocated in accordance with its priorities in order to optimize existing bandwidth usage. Regulating and limiting internet bandwidth usage is indeed an important thing when our internet connection is limited. We need to limit the bandwidth quota of each user connected to the Mikrotik Router. In Mikrotik Router itself, there are features that can limit bandwidth, namely simple queue and queue tree. In the use of VoIP services, bandwidth management is required to manage traffic on the network, the appropriate bandwidth settings can optimize the speed of data transmission. Looking at the internet needs, this research designs an implementation of bandwidth management using routerboard, which will be applied to IP-PBX and use raspberry pi as a server. The results of the research on bandwidth management implementation in simple queue and queue tree is each able to serve 6 users with PCMU codecs, from the test obtained packet loss value of 0.00% from 3 clients, and jitter has an average value of 167.37% from 3 clients.

Abstract

So far, there are many manual methods used to determine the freshness of chicken eggs, for example utilizing sunlight or a flashlight to illuminate the eggs in a dark place and then look at the contents of the chicken eggs for sorting. The same process has also been carried out by breeders or grocery traders to sort chicken eggs based on their quality. The purpose of this research is to make a chicken egg detection device using a conveyor, LDR (Light Dependent Resistor) sensor, lamp, LCD (Liquid Crystal Display), servo motor, esp8266 module and Arduino Mega Microcontroller as a processor. The performance results of this device affect the condition of the egg chicken to be detected. The results of this study, this tool has an accuracy of 95% in detecting egg quality, where the LDR sensor shows an ADC value of <260 for indicators of good egg quality, while ADC values ??of more than> 26 for indicators of poor egg quality. Once the eggs are detected, the servo will direct good quality chicken eggs to the right and poor quality chicken eggs to the left. Delivery of notifications and information to the website application is done online and in real time, and a good internet network is required. The time it takes for the system to transmit data from the time the system detects an egg until it appears on the website is 20 - 50 ms, according to ITU-T standards

Abstract

Many types of antennas work on the UHF band, including a 1 / 2l dipole antenna, Yagi-Uda array antenna, log periodic antenna, etc. The antenna of this type, its physical dimensions are adjusted according to the wavelength. The higher the working frequency, the shorter the wavelength, so the shorter the antenna's physical length. Bow tie antennas are often used as a TV receiver antenna, besides being relatively easy to manufacture, simple and significant. In this study, the antenna designed is a bow-tie antenna (butterfly) which works at a UHF frequency of 750 Mhz, arranged in an array, then fed with a 4: 1 balun (antenna impedance 300 ? to 75 ?), using a toroidal balun. With an air core in order to match the coaxial cable impedance of 75 ?. Antenna material from aluminum (solid). The research site was carried out in the Polinema Telecommunication laboratory. Antenna test results at an operating frequency of 750 Mhz show that the value of RL (return loss): - 11 dB, the coefficient of reflection G= 0.282, and the VSWR magnitude value = 1.786. The highest gain measurement occurs at the frequency: 567.25 Mhz (channel 33), which is 10.45 dB, and the average gain of the antenna is 3.19 dB. Because the VSWR price is less than 2, it can be said that the bow-tie antenna is still quite decent or good. It meets the criteria of an antenna parameter
