Abstract

The emergence of a new signal transmission protocol is a consideration in choosing the type of connectivity to be used, especially on a GPS Tracker. This study aims to develop a design of GPS Tracker testing stages using GSM and LoRa connectivity and determine the value of Packet loss in sending data using GSM and LoRa connectivity on a GPS Tracker. This research includes Research and Development research that uses experimental techniques. The results of the analysis of data communication and GPS Tracker LoRa signal reception resulted in an average packet loss value of 10%, RSSI of -116 dBm, and SNR of 0.2 dB. The analysis of data communication and GPS Tracker GSM signal reception results in an average packet loss value of 0%, RSSI of -65 dBm, and SNR of 23 dB. GSM connectivity has better quality in Non-Line of Sight (NLOS) test conditions in urban areas than LoRa connectivity. The performance and distance between the LoRa gateway transmitter and BTS with receiver (GPS Tracker) have a high influence on the quality of data communication and signal reception. The farther the transmitter is from the receiver, the worse the quality of data communication and signal reception, and vice versa. Keywords: Connectivity, GSM, LoRa, GPS Tracker

Abstract

The paprika plant (Capsicum annuum L.) is a plant native to South America that requires sub-tropical climate conditions togrow. In Indonesia, paprika grows well in the highlands at an altitude of 1000 - 1,500 m above sea level, requiring an idealtemperature of between 21ºC - 27ºC during the day and 13ºC - 18ºC at night. Extreme temperatures above 38ºC during theday and 32ºC at night can be detrimental to the growth of paprikas. To overcome the problem of temperature control in paprikaplants in Indonesia, the author designed a smart greenhouse with a temperature control system based on fuzzy logic. Fuzzylogic was chosen because of its flexibility in making decisions. This smart greenhouse uses cooling and heating actuators tomaintain the temperature inside. This research involved several stages of testing, including placement testing, actuator testing,and overall system testing. Placement tests showed temperature differences between various sides of the smart greenhouse, soit was necessary to use an actuator to even out the temperature inside. Testing the actuator explained that the cooling actuatorcontained a blower fan which functioned to even out the temperature inside the smart greenhouse and a peltier fan functionedto lower the temperature inside the smart greenhouse. Apart from that, there is a heating actuator in the form of a heater whichfunctions to increase the temperature inside the smart greenhouse. After collecting data from this test, proceed with testing theentire system. In this test, there are two conditions tested: day conditions with a setpoint of 24ºC and night conditions with asetpoint of 15ºC. Day conditions reach a steady state error of 1.26%, while night conditions do not reach a steady state errorbecause the cooling actuator is unable to approach the desired setpoint. The test results show that the system can maintain thetemperature inside the smart greenhouse. In addition, tests were carried out on paprika plants inside and outside the smartgreenhouse. The results showed that paprika plants grown in the smart greenhouse produced better development compared tothose planted outside. This research shows that a temperature control system based on fuzzy logic in a smart greenhouse canincrease the growth of paprika plants.

Abstract

Sektor industri menggunakan energi listrik yang sangat besar dan pada umumnya memiliki beban-beban induktif yang menyerap daya aktif dan daya reaktif yang cukup besar. Beban-beban induktif seperti motor, trasnfomer dan las listrik memiliki komponen induktor untuk magnetisasi. Magnetisasi akan menyerap daya reaktif yang akan menyebabkan peningkatan pada rugi-rugi energi sehingga faktor daya menurun pada sistem jaringan. Maka dari itu capacitor bank sering digunakan untuk memperbaikifactor daya. Namun, penggunaan capacitor bank pada jaringan yang mengandung harmonisa, dapat menyebabkan kenaikan nilai harmonisa akibat fenomena resonansi paralel yang terjadi. Sehingga detuned reactor sering digunakan untuk mencegah kenaikan harmonisa akibat penggunaan capacitor bank. Pada penelitian ini akan dilakukan analisis penambahan capacitor bank dan detuned reactor pada jaringan Convention Hall Grand Indonesia dengan metode pemasangan global compensation dan group compensation. Pada hasil penelitian ini, Saat capacitor bank capacitor bank terpasang faktor daya jaringan dapat diperbaiki baik menggunakan metode pemasangan global compensation dan group compensation mencapai nilai 95%. Penggunaan capacitor bank pada jaringan memberikan dampak kenaikan harmonisa pada jaringan dengan rata-rata kenaikan pada setiap panel mencapai 83% pada pemasangan menggunakan metode global compensation dan 136% pada saat pemasangan capactior bank menggunakan metode group compensation. Detuned reactor ditambahkan pada jaringan dengan dipasang seri terhadap kapasitor. Hasil penelitian ini menunjukkan baik dengan metode pemasangan global compensationataupun group compensation kenaikan harmonisa jaringan dapat dihindari dan bahkan dapat diredam. Hasil akhir nilai harmonisa jaringan mengalami rata-rata penurunan pada setiap panel mencapai 51% terhadap nilai harmonisa pada kondisi eksisting pada saat menggunakan metode pemasangan global compensation dan 47% saat pemasangan dengan metode group compensation.

Abstract

The rapid rate of population growth in urban areas, especially, can cause environmental problems, one of which is a decrease in the availability of agricultural land. On the other hand, global problems such as changes in world temperature and extreme climate change can disrupt stability in maintaining food availability. In this millennial period, many businesses have developed to fulfill their own food needs, starting from the application of theory to technology. One method that is being widely used by farmers in Indonesia is hydroponics. The research, which was conducted in a closed room in a house in Mojokerto for 10 days, experimented with growing pakcoy hydroponically using several control integrations in the form of indoor photosynthesis, automatic nutrient dosing, liquid level monitoring, and air circulation regulation. Based on the implementation of the research using a programmable logic controller, which compared the results of indoor and outdoor planting, it was found that the temperature of the planting environment and the temperature of the water in the indoor growing media remained in the range of 24℃-29℃, the air humidity was 63% -96%, the nutrient density was 789-1298 PPM, and leaf growth of 1-2 strands per day. Yields of pakcoy plants on indoor growing media give maximum results on leaf growth and leaf color, but are not better than pakcoy plants on outdoor growing media or those exposed to direct sunlight. Keywords: PLC, hydroponic, indoor, pakcoy, automatic.

Abstract

Batik is a historical heritage that can still be preserved and conserved to this day. One of the types of synthetic dyes used in batik coloring is indigosol dye. Indigosol dye is a type of water-soluble dye substance. To achieve optimal sunlight exposure, technology is needed in the form of a device that can assist in the drying process to optimize the drying results and anticipate rain. One of the technologies that can assist the industrial sector in the drying process of fabrics using indigosol is an automatic dryer. This device releases wet fabric when the weather is hot and clear, and it secures the fabric when the weather is cloudy and rain is expected or when rain suddenly falls. The use of PID control on the DC motor driving this device is used to gradually increase the speed before the first two seconds so that the hung fabric does not sway too much and burden the motor. PID control is also used to ensure a stable motor rotation before the first two seconds. This research involves several testing stages, including testing the system's response with PID control and sensor readings. Testing begins with determining the PID parameter values to be used and continues by observing the system's response to the motor values controlled by PID. Sensor readings are used to determine whether the sensor is functioning properly, and this is done by reading the sensors in the Arduino IDE application. The testing process yielded the PID parameter values: KP = 0.1 , Ki = 0.01 , Kd = 0.04. The system's response with these parameter values showed stable system performance with a delay time of 1.6 seconds, rise time of 1.6 seconds, peak time of 2 seconds, no overshoot, and a settling time of 2 seconds.

Abstract

Batik is a historical legacy that serves as a cultural heritage and a tourism commodity for the indigenous people of Indonesia. One of the synthetic dyes that can be utilized is the dye known as indigosol. Indigosol belongs to the group of oxidation dyes, where the color emerges after undergoing oxidation processes using oxidizers such as strong acids (HCl, H2SO4), with additional nitrite as a catalyst. To achieve an even and stronger color, optimal sunlight is required so that molecules can be excited perfectly. To attain optimal sunlight, a technology in the form of an automatic drying device is necessary to aid in the drying process. This helps optimize the drying results and anticipate rain. The device is equipped with UV lamps, an Arduino Uno microcontroller, a Light Dependent Resistor (LDR) sensor, a Raindrop sensor, and an Ultrasonic sensor (HCSR). The system of this device also employs logic that combines inputs from sensors and the microcontroller with outputs such as a DC motor and UV lamp, utilizing Fuzzy Mamdani logic. Fuzzy Mamdani logic is chosen due to its simplicity and ease of understanding compared to other fuzzy logics. Fuzzy Mamdani provides 5 membership sets for the LDR sensor and 3 membership sets for the Raindrop sensor, resulting in 1 output indicating the direction of the DC motor rotation. The use of this device significantly impacts the color output of indigosol-dyed batik fabric, especially during cloudy and rainy conditions, thanks to the UV lamp serving as a substitute for sunlight. The contribution of this device is quantifiable through the use of a histogram of images, depicting changes in color density in detail. Therefore, this device not only serves as a practical solution but also delivers a positive impact on the final outcomes in the Indonesian batik industry.

Abstract

Railway is one of the ground transportation modes that has characteristics and advantages more efficient compared to other ground transportation modes. However, accidents at railway crossings remain a serious issue. To reduce accidents between trains and road users at level crossings due to negligence or errors in the system, or due to road users' lack of discipline, there is a need for automatic crossing barriers, such as the use of automatic railway crossing gates integrated with components, making it safer and minimizing the possibility of road users attempting to pass through railway gates when they are closing. This research employs arduino UNO components, HC-SR04 ultrasonic sensors, FC-51 infrared sensors, DC motors, L2986N motor drivers, 16x2 LCD with I2C module, LEDs, power supply, and an emergency stop. The railway crossing gate system is designed with a working principle using sensors to detect trains and objects around the crossing. Testing of the ultrasonic sensor successfully detected trains at a maximum distance of 5 cm, with angles of 20° and 30° providing optimal initial detection. The infrared sensor showed rapid response to approaching objects, and using PWM duty cycle 27,4% provided optimal performance for the gate's sliding movement. Additionally, testing of the LED, LCD, buzzer, and emergency stop button functioned according to their purposes. The overall testing results of the system concluded that the design of the railway crossing gate system was successfully integrated to enhance safety at railway crossings and optimize train operations.

Abstract

This research analyzes the total attenuation loss in Fiber to the Home (FTTH) networks with the aim of improving signal quality and network efficiency. The study results indicate that the attenuation values at ODP 122 and ODP 123 pose challenges related to total attenuation loss. The standardization of attenuation is 28dB, while the calculated result shows 19.021dB at ODP 122. The Fiber Optic's output power is 3 dBm with a standard input power of -28dBm. The received power at ODP 122 and ODP 123 is -16.021 dB and -15.972 dB, respectively. Although the error values are acceptable, the study suggests improvements in network design, appropriate component selection, and attenuation management strategies to optimize signal quality. Factors such as cable length, cable type, and connectivity also significantly influence network performance. Keywords: Fiber to The Home, Fiber Optic, Loss

Abstract

The development of EBT in Indonesia is still far from the target of the National Energy Policy (KEN), namely the EBT mix of 23% in 2025 and 31% in 2050. One form of EBT development is utilizing solar energy in building technology that has high energy efficiency so that the number of electrical energy consumption is close to zero or called nearly Zero Energy Building (nZEB). Therefore, it is necessary to design the most optimal rooftop solar power plant (PLTS) so that it has good energy production and economic feasibility. To get good energy production, a simulation is carried out using HelioScope software by inputting data on the mechanical and electrical segments so that the amount of energy that can be produced by the rooftop solar power plant is obtained in detail. The results of the simulation of the rooftop solar power plant system that is installed on-grid in HelioScope are composed of 96 monocrystalline solar panels of Trina Solar TSM-DE20-605W (605W) and 3 3-phase inverters of Growatt MID 17KTL-X. The rooftop solar power plant produces an annual production of 84,08 MWh with a performance ratio of 82,1%. Thus, the average percentage of energy supply from rooftop solar power plants is 39,82% or can be said to be good in supplying the electrical energy needs of buildings so that the nZEB can be developed. From the simulation results, the economic feasibility is known, with the Break Even Point (BEP) reached in 12,4 years of the 25 years project period, and the Net Present Value (NPV) and Return on Investment (RoI) are positive, indicating that the rooftop solar power plant is profitable and feasible to develop. Keywords: Rooftop Solar Power Plant, HelioScope, nearly Zero Energy Building, Feasibility Study
