Abstract

Light is a source of energy that is needed in human life. In hospitals, artificial lighting is very necessary, especially in operating rooms that are impermeable to natural light and must be sterile from room bacteria. Artificial light exposure that does not meet the SNI standard for room lighting causes various problems. Therefore, in this study, a tool to control the intensity of artificial light according to the SNI standard in hospitals was designed. This research uses measurement, calculation and comparison methods. The first measurement is to measure the value of the light intensity of the lamp, then measure the temperature value in the room, the last one is to sterilize the room bacteria. From these measurements, values ??are obtained to be compared in reaching conclusions. From this research, it can be concluded that the monitoring system with the LDR light sensor can read the value of the light intensity properly according to the digital lux meter in the morning at 400 lux, 200 lux in the daytime, and 120 lux at night. Then the DHT-11 sensor can read the temperature value in the room according to the HTC comparison with the morning temperature is 25 degrees, daytime 29 degrees, afternoon 27 days, and night is 24 degrees. To help kill room bacteria, a Utraviolet lamp is used with a light for 2 hours in the morning.

Abstract

One of the products of Indonesia's fishery is Tuna. To overcome the increasing demand of the world market, the Ministry of Marine Affairs and Fisheries provides routine information on map information on potential zones of fish, especially Tuna. However, for some fishermen it is relatively difficult to access the map because it requires the internet, so it becomes an obstacle in disseminating information on this fish potential zone map. From the above problems, such as the lack of knowledge of fishermen regarding the condition of the location of tuna points, while the current information is relatively difficult to obtain for some fishermen, so it is necessary to develop a "Coordinating Information System for Tuna Fish Estimates for Fishermen". With this system, it can make it easier for fishermen to subscribe to tuna fish coordinate update information either through the website or via SMS. The method used to determine the coordinates of the fish on the PDPI map is to use image processing with the medium scaling method SMS was chosen because it is one of the media for transferring information that is widely used among middle to lower income fishermen. From the results of testing and analysis of software. digital coordinates can run with an average reading duration of 31.651 seconds. The map error tolerance for longitude is 1099,591 meters and for latitude is 1401,939 meters.

Abstract

In this article, the implementation of wirelessVoIP at State Polytechnic of Malang uses microtic management with the aim of knowing the QoS (Quality of Services) performance between systems without microtic management and systems using microtic management. In the implementation of this system, two tests were carried out, namely QoS testing when without proxy management and when using proxy management. From the two tests, the performance will be compared by doing data compilation using the VQ manager software. The QoS parameters to be taken are delay, jitter, packet loss and throughput. From the measurement it is known that when the VoIP server serves <= 3 calls simultaneously, the MOS value between the managed system (MOS = 3.7) and the system without management (MOS = 3.7) is almost the same because the value of delay and packet loss in the system without management and systems with management did not differ much, namely 107 ms and 83 ms, and the packet loss value was the same, namely 5%. And when serving> 3 simultaneous calls, there is a difference of 0.18 from the MOS value between the managed system (MOS = 3.48) and a system without management (MOS = 3.3) with a value of delay and packet loss for systems without management and systems with management, namely 527 ms and 340 ms, and the packet loss values ??were the same, namely 8% and 7.2%.

Abstract

In the Modern Era, a source of electrical energy is very necessary, given the large number of electronic equipment that really requires a source of electrical energy. Solarcell is a device or component that can convert light energy into electrical energy. However, the energy used in this solar panel needs to be considered the efficiency of its use. Therefore it is necessary to monitor currents and voltages and loads in real time to determine the energy needs of solar panels for lamps. Monitoring of voltage, load and current on this solar panel is based on a microcontroller. The voltage generated by the solar panel and the battery voltage is measured using a sensor. It takes a Web and a modem device to send solar panel measurement data from a distance, with remote monitoring makes it easier to find out what the voltage and load is without having to be in place of the solar panel. Web as a control for lights, blackouts, dim and bright lights, on the web can monitor voltage and current values. The results of the microcontroller ADC are able to send data to the web. The data stored in the ms.excel file contains the voltage from the solar cell, the current at the load and the time when storing and charging the battery. The lights can only last 5 hours when all loads are active (ON), while charging (charging) for 13 hours when the battery is empty.

Abstract

Currently, most motorized vehicle safety technologies, especially cars, still rely heavily on the manufacturer's default safety system from the car system itself. By using a security system from the factory default there are still shortcomings because a motorized vehicle or car can still be used by anyone and there is no age limit in its use. For that, we need a car safety system that is able to prevent the occurrence of car theft and underage drivers. The purpose of this research is to design a central lock security system for motor vehicles, especially cars, using e-KTP identification to improve the security system and reduce underage drivers. For the identification process of e-KTP ID using the RFID reader MFRC522. The RFID reader is connected to the Arduino Nano as a controller. The results of the research used the RFID reader to read e-KTP ID in a vertical and horizontal position with a distance of less than 12 mm. When there is an acrylic barrier and a glass barrier the maximum reading distance is less than 9 mm and the plate barrier cannot be read. The existence of obstacles makes reading the e-KTP card will be reduced.

Abstract

In swallow nest cultivation, swallow breeders still have difficulty in tropical climates, one of which is maintaining the temperature and humidity in the swallow nest room to be stable and to know the value of swallow population. When the temperature is hot, the swallow room will become dry which impacts on the nest is damaged and the swallow is not comfortable living there. Therefore, a system that can be easily managed by swallow farmers is made so it can help reduce hot temperature and lack of humidity in the swallow nest room by using a sprayer that works automatically. In this system, there are temperature and humidity detection module which functions to detect the temperature valueand humidity when the room is hot / dry, the detected value will be processed by the microcontroller so that it gives an active sprayer command if the room temperature is hot, while the swallow detection module that uses infrared sends the movement value if there is a moving object. The value of the system will be sent to a cloud database which will be conveyed via the farmer wallet smartphone application. The accuracy level of the infrared detector sensor module and the air humidity sensor is very good, so that it can control the temperature conditions in the swallow room which is 27 degrees C and a stable humidity at a value of 80%. The stability of temperature and humidity produces swallow nests which have high selling value.

Abstract

Analog telecommunication system equipment is now starting to develop and be replaced with digital telecommunication systems, one of them is in the audio signal processing. The focus of audio processing is audio crossover. Audio crossover in development there are still many who use analog systems. This analog system has disadvantages when adjusting the sound balance because it still uses analog filters to balance it. It is necessary to develop a technology that aims to create a digital-based crossover audio system using the STM32L4, so that by using this digital-based signal processing it is able to adjust the sound more specifically than the signal processing used analog based. This digital filter uses the Finite Impulse Response (FIR) method. Testing audio crossover using STM32L4 produces a digital-based crossover audio system design using a STM32L4 microcontroller with a voltage of 3.3V as power supply, mp3 player as sound input device, FIR filter as digital filter processing, LM386 as sound amplifier and speaker as sound output for crossover audio on rangelow frequency (200Hz to 4000Hz), high (2200Hz to 6000Hz), medium (200Hz to 4000Hz).
