Abstract

The condition of the broiler cage during the rearing period can affect the quality of the chicken meat produced. Conditions in the cage that are not comfortable for chickens can cause disease and inhibit the growth of chickens. One of the main factors that can affect the condition of the chicken coop is the temperature and humidity of the air. A comfortable temperature for chickens is between 19oC to 33oC, and humidity is between 30%RH to 70%RH. In addition, the air in the chicken coop is also susceptible to being polluted by ammonia gas produced from chicken manure. Ammonia gas with concentrations exceeding 25ppm for more than 8 hours can harm the health of chickens and breeders. The purpose of this study was to design a system that can monitor conditions in the chicken coop in the form of temperature, humidity, and ammonia gas concentration. The system uses a NodeMCU ESP8266 microcontroller, a DHT11 temperature and humidity sensor, and an MQ-135 gas sensor. The system made can measure temperature and humidity, with an average error of 1.97% for temperature, and 3.55% for humidity. Meanwhile, the results of the measurement of ammonia gas concentration have approached the characteristics in the datasheet. The stored measurement data is visualized on the ThingSpeak web application. In addition, the system can also send warning messages via the Telegram application when the measurement value is abnormal or there is a sudden change in value.Keywords: Broiler, temperature, humidity, ammonia gas

Abstract

Greenhouse is one of the modern methods of plant cultivation by manipulating environmental conditions according to the desired conditions. To produce healthy and fertile greenhouse plants, several factors are needed, such as temperature, sunlight, water, and soil moisture according to the type of plant. In this study, the design of a sensor node system was carried out as a monitoring of soil moisture and temperature in the greenhouse. In this design, the DHT22 sensor is used as a temperature and humidity detector, capacitive soil moisture sensor SEN0193 as a greenhouse plant soil moisture detector. The readings from the sensor will be processed by the ESP32 microcontroller so that it can be understood by the user, then sends the data to the pump controller node as input in the form of sensor data. The test was carried out several times to find that the output data from the sensor node was data that was in accordance with the circumstances. The soil moisture sensor test SEN0193 was compared with a 4 in 1 soil meter to obtain an average error of 1.15%. The DHT22 temperature sensor test was compared with a temperature thermometer

Abstract

In order to meet the electricity demand, we need to build a reliable distribution system. However, studies found that providing a service without interruption is challenging, especially avoiding voltage drop interruption remains a difficult task. Although voltage drop interruption is ineluctable, the distribution system usually can tolerate it at a certain level or threshold. Based on the regulation standard by the Ministry of Energy and Mineral Resources of Indonesia in 2009, the safe thresholds are between -10% to +5% of the standard value. As a part of the maintenance procedure, an engineer must ensure that an electrical power distribution system follows those rules to avoid voltage drop interruptions. This study observed the power flow of four connected feeders (Buluagung, Glagah Sari, Tutur, and Kayoman) at the Sukorejo main substation. The electrical power flow of each feeder fluctuated as follows: for Buluagung, the maximum voltage drop was 4.85%, Glagah Sari was 6.65%, Tutur was 2.59%, and Kayoman was 18.89%. Kayoman had te highest voltage drop, and the value passed the defined standard from the Ministry. Thus, this study proposed a framework to reduce the voltage drop value in Kayoman by adding a capacitor bank by analyzing the loss sensitivity along with the norm method. This study performed eight simulations and simulation number four, with additional capacitor installation on buses 8, 9, 12, and 16, giving the optimal result as the voltage drop value reduced to 8.71% for Kayoman. The real and reactive power losses were 934.43 kW and 1,303.54kVAR, respectively.Keywords: distribution system, loss-sensitivity analysis, reactive power difference, voltage drop

Abstract

The Center for Domestic Trade Studies of the Ministry of Trade of the Republic of Indonesia stated that chicken meat is one of the main commodities in meeting the animal protein needs of the community. This causes the community's need for broiler meat to be quite high. The high number of people's need for broilers makes the health of broilers something that deserves attention. The environmental condition of the chicken coop is one of the factors that affect the health of chickens. To maintain the health of chickens, it is very important to create a comfortable atmosphere for chickens, by paying attention to air circulation and humidity, and adjusting the density of the cage. For now, monitoring temperature and humidity, as well as setting the density of the cage is still carried out manually will take a lot of time and require a lot of manpower. For this reason, we need an application that can help monitor the temperature, humidity, and density of the cage. In this study, an application design assisted by the PyQt5 library will be carried out and aims to monitor the temperature, humidity, behavior, and distribution of chickens through an application that will be developed with the help of Internet of Things technology and Computer Vision technology. Keywords: Broiler chicken, computer vision, YOLOv4, PyQt5, Io

Abstract

The demand and need for network services and mobile data services are very high, which encourages the use of 5G NR technology. Currently, 5G NR technology has not been fully implemented in Indonesia. As a result, a 5G NR MHz network planning was carried out in this study based on the performance of the 4G LTE network obtained from the drive test method in the area of Brawijaya University, Malang. The coverage planning uses the cost-hatta propagation model. This propagation model is used with the consideration of flexible frequency usage, and the city of Malang is an urban area. The purpose of this study was to determine the site location mapping (gNodeB) and 5G NR network coverage at Brawijaya University Malang. So the results can be taken into consideration in planning the 5G NR network. 5G NR network planning is created by calculate the cell radius, coverage, calculate the number of sites, and mapping them on a planning tool called Atoll.

Abstract

This paper describes the simulation design of a boost converter that has a high voltage gain. High voltage gains are obtained using the new z-source dc-dc boost converter topology circuit. This converter uses an impedance network which is used as a bridge between the source and the converter. The Z-source converter overcomes the conceptual, theoretical and limitations of conventional voltage source converters and current source converters. The stress on the diodes and switches is lower than the boost converter, so efficiency is improved. At a low duty cycle, this converter is able to produce a higher voltage gain than the boost converter. Both converters are then tested with the same specifications with the aim of knowing the output comparison between the two converters. The test of the two converters is simulated with the PSIM application and analyzed at several stages of testing. The test includes the specifications of the components used, analysis of each component in transient and steady state conditions, comparison of the voltage gain tested at varying duty cycle values, as well as calculation of voltage stress and current stress on the z-source converter and boost converter circuits.Keywords: boost converter, z-source converter, high voltage gain, voltage stress, current stress, PSIM
