Abstract

Industrial accidents are accidents that occur in the workplace, especially in an industrial environment. The most important factors in the occurrence of work accidents are technical equipment, work environment, and the workers themselves. Lighting that is not enough to illuminate workers when using machines can cause work accidents during the production process. In addition, hot conditions can also cause work accidents because hot temperatures make the body uncomfortable at work, reduce agility, interfere with the carefulness of the brain, and ease emotions so that workers cannot concentrate and can cause work accidents. The purpose of this research is to create a system that can detect temperature, smoke, and light in a GSM-based industrial environment. This system can help prevent industrial accidents by obtaining information about industrial environmental conditions for workers in the form of SMS. Temperature, smoke, and light sensors will send SMS information when each sensor exceeds the threshold value specified in the program. Information delivery is carried out using 3 different providers, namely Three, Indosat, and Telkomsel by comparing the amount of delay. The test results can be concluded that the three sensors can work well. The temperature sensor can detect temperature with an average error value of 0.03%. The smoke sensor can detect smoke with an average value of 0%. Provider Three can send information with a small average delay, namely 1.46s. Indosat providers can send information with an average delay of 3.68s. Telkomsel providers can send information with an average delay of 1.52s.

Abstract

In this study, a tool for telemonitoring dissolved solids was designed in the filtration of laundry wastewater which is used as a hydroponic planting medium, pH sensor, and TDS sensor to measure and obtain dissolved solids data that affect the plant growth process, then these data will be processed by the Arduino microcontroller. Nano so that the final result will be stored in the database and sent wirelessly via Wemos D1 so that it can be displayed in the android application. The research that has been done, obtained the results of the measurement value of dissolved solids of laundry wastewater before filtering for a Ph value of 6.63 and a solution concentration of 250 ppm. After twice filtration, the dissolved solids for Ph were 6.32 and TDS was 1276 ppm. Based on this study, the results of telemonitoring the average dissolved solids of laundry waste filtration water after being used as a hydroponic planting medium with a PH value of 6.86 and a TDS of 681 ppm. Because the dissolved solids value of the planting medium is not in accordance with the minimum standard of use in hydroponic agriculture (PH = 6.5; solution concentration = 850 ppm), it can be concluded that the use of laundry wastewater filtration causes plants to grow slowly and abnormally (stunted).

Abstract

Pests are one of the main enemies of rice farmers who at any time can attack crops. The impact of rice pest attacks can reduce the production of rice crops, causing crop yields to decline. One of the pests that often unsettling rice farmers is bird pests (Passer spp.) and rats (Hundred argentiventer), the pest attack is determined by the state of the climate, and the unwise use of insecticides and the manual expulsion of pests takes a lot of time.  To reduce the above problems in this study will develop new innovations in agriculture, through The Repellent Tool Automatically is one way to help rice farmers to pollute the environment and expulsion manually. In this tool is installed a micro controller raspberry pi 3 as a link between the pear sensor and the camera module, in addition raspberry pi 3 is integrated with the smartphone application in real-time for the process of monitoring the presence of pests and using speakers to repel pests. The test results obtained by rat pests are disturbed when the speakers emit an ultrasonic wave frequency of 34-45KHz and bird pests will be disturbed if the speakers emit a frequency of 60kHz. The PIR sensor can detect the presence of rat pests with a vulnerable distance of 5-50cm, while the camera detects the movement of bird groups and gets an accuracy percentage of 44.4% of the test results and an average delay of 1.08 seconds.

Abstract

Birds are animals that are very much favored by the community. Currently, lovebirds is popular to be kept and even bred, because the cost of maintenance is cheap and the opportunity to raise it is very good and promising. So that many people are interested in pursuing lovebird livestock business even though breeding is neither easy nor difficult. The reseach purpose was to create monitoring system for the quality of lovebird eggs to be declared hatchable and unable to hatch by utilizing conveyor machines, infrared sensors, LDR sensors and servo motors. All these components are connected to smartphone via mcu node. The captured data is sent to firebase and monitored on the smartphone. The data includes the number of fertile and infertile eggs, and the eggs resistance value scanned by the LDR sensor. The system implementation is done by placing sample of lovebird eggs on conveyor machine and then testing it one by one, then the resistance value is displayed on the smartphone, then the average value is calculated, and the percentage of the sensor is successful in reading the egg condition. The results of testing on lovebird eggs produced 2 conditions, fertile and infertilee. If the resistance value is > 505ohm then the egg is declared fertile and it’s declared invert if resistance value is < 505ohm. In distance testing, the most accurate distance is 1-24cm, the sensor cannot work accurately if the distance between eggs shorter, because the sensor takes time to return to the initial scan mode.

Abstract

Voice over Internet Protocol (also called  VoIP,  IP Telephony,  Internet Telephony  or  Digital Phone)is a   technology that enables remote voice conversation through internet media. Voice data is converted into digital code and streamed over a network that delivers data packets, rather than through a regular analog telephone circuit. In VoIP  communication,users make telephone connection through a terminal in the form of a PC or a regularphone. By calling voip,  manyadvantages that can be taken in terms of costare obviously cheaper than traditional phone rates, because IP networks are global. IP Phone can be added, moved and changed. This is because  VoIP can be installed in any ethernet and IP address,unlike conventional phones that must have their own port in Sentral or  PBX  (Private branch exchange). In this study implementing connectedness between servers using single board computer   installed  elastix operating system that aims to implement  prefix for between servers and use some audio codecs. The results of telephone research using prefix and without prefix as many as 6 clients or 3 pasng calls simultaneously the highest packet loss  value in codec speex   with prefix  of 2.34%. The  highest bandwidth value used is with pcmu prefix codec with an average of 82.3 Kbps and without prefix 79.3 Kbps.
