Abstract

The capacitive slit is a method of making the impedance value to be resistive. To achieve this goal is a challenge in addition to the slit antenna and gives impact to gain as one of the important parameters in antenna design. The antenna gain in a particular direction is defined as 4π times the ratio of radiation intensity in that direction to the power received by the transmitter antenna. In this research, the proposed capacitive slit method was tested on the hexacula omnidirectional broadband antenna operating on frequency 0.85-3 GHz and gain 4.8 dBi. The testing was conducted to obtain the gain improvement of the hexacula omnidirectional broadband antenna. The placement of the capacitive slit was implemented on double strip antenna with 4 times experiments. The best experiment result was obtained when three capacitive slits were placed on different strips. The capacitive slit was designed by analyzing the average value of input impedance before calculating the dimension of the capacitive slit that applied to the antenna. The experiment result shows that the best value of antenna gain is 7.19 dBi. The gain increment is linear to the number of capacitive slits applied to the antenna.

Abstract

The wireless communication technology is grow up very fast and varied. The transmission equipment, andantenna will be effected by it. At this time many applications work in frequency band 0.3 GHz - 3.0 GHz,such as television, GSM, CDMA, and WiMAX. However, its used one-antenna for one technology. So weneed an antenna that can solve this problem, the Hexacula omnidirectional antenna will created to solvethis problem. After measured in laboratorium of microwave and in environment of ITTelkom, operatingfrequency 736.2 MHz-3000Mhz in VSWR≤1.5 and 600MHz-3000MHz in VSWR ≤2.0, Omnidirectional,Ellips Polarization, gain 6,353±1,428 dBi and the average impedance is 52.00821+j8.46. The result ofmeasurement already achieve the specification except operating frequency and polarization. If want toachieve the oprating frequency as the specification, suggestion are make a smaller slice in upper stripsfrom 2mm to 0.1mmand make conic higher than before that is from 3.1cm to 5.0cm. If want to achieve thepolarization as the specification, suggestion are use the pencil beam antenna when measure thepolarization and dielectric size must be match with width strips.

Abstract

In general, only one antenna is used for one application. To streamline the use of an antenna, a broadband antenna can be utilized for various applications. One broadband antenna suitable for various applications are broadband antennas six branches of the plate with a single capacitive gap binomial method. This antenna works in the frequency range 0.81 GHz - 3 GHz, which has a bandwidth of 2.19 GHz with a VSWR ≤ 1.5. This antenna has a dielectric antenna different. Dielectric antenna using materials from household waste such as plastic, paper, stereofoam, and others. It became one of the benefits is because the antenna is able to utilize waste materials for the application of technology. This antenna is relatively large dimensions so that the antenna is suitable for use in the transmission system and not be used as a suitable handset. Applications that can use this antenna including GSM 1900, Wifi 2.4 GHz, amateur radio, and more. This antenna uses a binomial method and a single capacitive gap as a method of widening the bandwidth. Binomial method is used to make the antenna impedance into tiers binomial pointless to shrink the transition effect antenna impedance of each level. slit method serves as a single capacitive impedance value improvements that will affect to the bandwidth of the antenna.

Abstract

Smart Gesture is one of the interesting technologies to be developed. Smart gesture can be harnessed into a vast range of things to ease the people work people. In general the suitcase uses to pack the stuff which is pulled manual. By using a Smart Gestures suitcase, user does not need to pull the trunk anymore, it can be controlled by using gloves. Smart Gesture is applied on a suitcase using the accelerometer sensor to start the motor. It controls the suitcase on the level of the slope of the hands resulting from the accelerometer sensor. To minimize the discharge of excess power in pulling the suitcase, it makes the user to control the suitcase without pulling it directly.

Abstract

Generally, in Banda Aceh there are several entertainment venues that provide water dancing which are still monotonous and unvaried. This situation is caused by the absence of new innovations that are displayed to be enjoyed. To deal with, this final project created an this application can provide water dancing with varied patterns. This tool can be controlled via android. Furthermore, it uses Arduino Mega, DC Motor, L293D motor driver, Android.

Abstract

Many victims are caused by floods every year due to inadequate warning systems that exist today. Making a flood disasterwarning application is used to receive information in the form of the latest water level conditions that are designed usingultra sonic sensors, So as to minimize the number of flood victims. Ultrasonic sensors detect water levels above 11cm, soArduino sends a signal to Android to instruct the Android to send a water warning SMS that has reached the standby pointto the user using the SMS Gateway Method, so users can receive SMS notifications about water levels in real time.

Abstract

At this time to turn on the waterwheel on shrimp ponds, electricity sources from PLN are used or often also use generatorsas a backup power source. So to overcome this problem, a hybrid system with an energy source from Photovoltaic (PV) -PLN-Batteries with voltage output is used to drive a waterwheel in a shrimp pond. The purpose of this study is to reducethe use of electrical energy from PLN and also generators with fuel oil which will gradually run out of energy sources. Themethod used includes PV with a power of 200Wp and an output voltage of 12V, the energy generated by the PV is receivedby the solar charge control which is stored in a 3000 mAh capacity battery. The output voltage generated from PV isdetected by the ZMPT sensor 101B (voltage sensor) which will provide input data to the PLC to be processed with amaximum voltage of 25VDC, when the battery voltage is empty, the PLC will change the input of electrical energy that wasoriginally supplied from the battery into an electrical energy input from PLN sources. The results of the system simulationare obtained that every condition that is tried can be run in accordance with expectations, namely the voltage sensor candetect each voltage signal from the three voltage inputs originating from PV, PLN and also the battery.

Abstract

This study aims to examine the implementation of the concepts of balance and justice in Islamic financial institutions in Aceh, focusing on their role in promoting not only economic benefits but also fairness and social welfare. Using a qualitative descriptive approach supported by field data and document analysis, the research explores the opportunities and challenges encountered in operationalizing these values. The findings reveal several opportunities, including enhanced public trust, local economic development, and increased financial system stability and resilience. However, the study also identifies significant challenges such as limited public understanding and education, inadequate infrastructure and technology use, shortage of qualified human resources, suboptimal regulatory oversight, competition with conventional financial institutions, socio-cultural constraints, and difficulties in product implementation. To address these issues, the study proposes several strategies: adherence to sharia principles in operations and transactions, comprehensive sharia-based supervision, community outreach and education, collaborative initiatives with governmental bodies, innovation in sharia-compliant financial products, robust risk management, and a firm commitment to social responsibility. Contribution: This study contributes to the discourse on Islamic finance by emphasizing the practical integration of maqashid al-shariah in institutional governance. It also provides insights for policymakers and practitioners seeking to strengthen the role of Islamic financial institutions in achieving socio-economic justice in regional contexts.
