Abstract

This study describes the methods and discussion for analysing the comparison of the two types of antennas, namely the 24-star patch and 27-star patch array 2x1 microstrip antennas which are then also compared through performance comparisons on LTE router CPE modem. The 27-star patch has a better value in measurement results than the 24-star patch antenna and in the simulation results and performance results, the two types of antennas have various values. In the simulation results, the best parameter values for Return loss, VSWR, and Bandwidth are in the 24-star patch, but for Gain and Directivity are in the 27-star patch. In the results of the performance comparison, the values of the two antenna variations are identical and fluctuate which can be caused by the influence of the modem connection with the access network.

Abstract

Gili Ketapang Island is one of the strategic areas for marine conservation in East Java, offering various main activities such as snorkeling, diving, recreational fishing, religious tourism, both traditional and modern fishing, and the development of marine cultivation through floating net cages. Floating net cages are becoming increasingly popular as a method of fish cultivation in Indonesia. However, fish theft in floating net cages remains a frequent and significant problem for fish farmers, causing substantial losses. Therefore, a fish theft detection device is needed to help reduce cases of fish theft in floating net cages. In order to develop this fish theft detection device, the use of PIR sensors and accelerometers is required. PIR sensors detect human movements entering or exiting the sensor's range, while accelerometers are used to measure the angles generated by ocean waves, which will be set as triggers for the PIR sensor. The characteristics of PIR sensors and accelerometers are crucial indetermining the accuracy and reliability of the fish theft detection device. Therefore, in-depth research on the characteristics of PIR sensors and accelerometers to be used in the fish theft detection device in floating net cages is necessary. As a result, it is expected that the detection device will work effectively and assist fish farmers in preventing fish theft in floating net cages.

Abstract

Microstrip antenna is a type of antenna that has several advantages, namely having a small size and weight, easy and cheap to implement, being able to operate on single, dual or multi bands, can produce circular and linear polarization. However, there are several disadvantages of microstrip antennas, namely that they are easy to deform due to pressure and temperature from outside or from the antenna itself, causing the antenna to bend or bend which results in decreased antenna performance due to worse antenna parameters. This study analyzes the effect of bending the orientation of the xaxis and y-axis on the performance of the 27 star microstrip patch antenna. The design of the 27 star-shaped microstrip antenna with a copper conductor. The analysis was carried out using two methods, namely simulation using the CST Studio Suite 2021 application and antenna measurements using a vector network analyzer. The study used is analytical in nature which refers to the results of simulations and real measurements. The objectives to be achieved in writing this research are to design a 27 star microstrip antenna and analyze the effect of bend on antenna performance. The methods used in this research are: literature study, antenna design, antenna measurement, analysis of simulation results and antenna measurement results, as well as drawing conclusions and suggestions. The measurement and simulation results show that bending affects the quality of the antenna resulting in a change in the parameter results, this occurs due to a decrease in performance due to changes in the shape of the antenna which are different compared to the flat state, so that the parameter results have worse values than before Keywords: Microstrip antenna, X-axis bending, Y-axis bending, CST Studio Suite, ARINST VNA

Abstract

Bencana alam sering kali mengakibatkan gangguan pada sarana dan prasarana umum serta kesulitan dalam kegiatan pencarian dan perbaikan. Dalam kondisi seperti ini, catu daya portabel yang menggunakan baterai menjadi solusi yang berguna untuk menyediakan sumber energi cadangan. Namun, penggunaan baterai pada catu daya portabel juga memunculkan kekhawatiran terkait estimasi penggunaan daya yang tersedia. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan sistem pemutus catu daya dan algoritma estimasi lama penggunaan baterai untuk memastikan penggunaan daya yang optimal dan mencegah kehabisan daya secara tiba-tiba. Dalam penelitian ini, dilakukan pengujian terhadap perangkat yang mampu mengukur tegangan dan arus baterai dengan tingkat akurasi yang tinggi. Hasil pengujian menunjukkan bahwa perangkat memiliki akurasi pengukuran tegangan sebesar 99,02% dibandingkan dengan pengukuran menggunakan voltmeter. Selain itu, perangkat juga mampu mengukur nilai keluaran dari sensor arus dengan akurasi sebesar 94,2%. Sistem pemutus catu daya pada catu daya portabel telah berhasil dikembangkan untuk mengatasi penggunaan daya yang melebihi toleransi sistem. Jika daya yang digunakan melebihi 350 Watt, sistem akan memberikan tanda peringatan dan dalam jangka waktu tertentu, jika beban tidak dikurangi, sistem akan otomatis memutuskan penggunaan beban tersebut. Sistem ini juga mampu membatasi penggunaan energi pada baterai agar tidak melebihi nilai minimum yang diperbolehkan. Selain itu, estimasi penggunaan baterai juga dapat dihitung berdasarkan jumlah beban yang terhubung dengan tingkat akurasi sebesar 95,58%. Penelitian ini memberikan kontribusi penting dalam pengembangan catu daya portabel untuk situasi bencana alam. Dengan adanya sistem pemutus catu daya dan estimasi penggunaan baterai yang akurat, pengguna dapat mengoptimalkan penggunaan daya dan menghindari kehabisan daya yang tidak terduga. Hal ini akan meningkatkan efektivitas dalam upaya pertolongan pertama, khususnya dalam hal penerangan dan komunikasi, serta memberikan dampak positif terhadap psikologis para korban bencana.

Abstract

In floating cage cultivation, security is one of the important aspects to be considered. Possible threats include fish theft, theft of cultivation equipment, predator attacks such as birds or predatory fish. The importance of security devices against fish thieves in floating cages on Gili Ketapang Island cannot be underestimated. In an effort to protect and maintain the sustainability of fish farming, the use of effective security devices is essential. By installing security devices such as suspected movement detection, notification delivery, and sirens, cage owners can increase the likelihood of detection and prevent acts of fish theft. These devices provide better surveillance and allow cage owners to respond quickly in case of suspicious behavior. To prevent fish theft in floating cages, research was conducted to design a cage security system. An effective security system can help identify and prevent theft or attacks on floating cages, improve supervision, and provide a sense of security to cage owners. In this final research project, we will analyze the performance of ESP32 Cam in sending images, analyze the performance of SIM800l module in making calls and power consumption in the security system of fish theft in floating cages. The implementation results obtained that the security system using a 17Ah LifePO4 battery was able to be active for 12 hours in standby conditions with a total power of 2.88W and in a state of detecting movement the system was able to be active for 2.5 hours with a total power of 35.96W. In this study, a security system was designed for monitoring cages remotely using ESP32 Cam using telegram bot assistance, for motion detection using the SIM800l module with PIR sensor as object detector and triggering the SIM800l module to make a call. The results of this study are that for monitoring, ten tests were carried out and had a success percentage of 90%, for motion detection it had a success rate of 80% by conducting ten tests. Keywords : security system, battery life, image processing, motion detection.

Abstract

Antennas are expected to keep up with an era that requires flexible and wearable forms. In this use, it is possible to require bending of the microstrip antenna which changes the characteristics or parameters. In this research a microstrip antenna is designed with a 30-star ground plane patch in the form of a staircase working at a frequency of 2.4 GHz. Design and simulation were carried out in CST Studio Suite 2018 software and measurements were carried out with a Signal Generator and SpectrumAnalyzer. The simulation results show that bending causes yield degradation only in the parameters of the microstrip antenna, which is axial ratio that has an impact on polarization. And the measurement results show that there is degradation only in the axial ratio parameter which affects polarization. The smaller the bending radius that is done so that the antenna bends more, the way the antenna works will change. Keywords: Microstrip Antenna, Bending, Radiation Pattern, Polarization, Axial Ratio

Abstract

Mikrostip antennas have various dimensions and placements that depend on needs. In some antennas, especially antennas placed on uneven surfaces, it can allow bending of the microstrip antenna which can affect the characteristics or parameters of the antenna. In this study, a microstrip antenna with a 21-star patch with a staircase shape on a groundpalne that worked at a frequency of 2.4 GHz. Design and simulation were carried out using CST studio suite 2021 software and measurement were carried out with nanoVNA SAA2. The simulation results show that bending causes degradation in the microstrip antenna parameters which include return loss and vswr. On the contrary, the measurement results show that there is an increase in performance on the return loss and vswr parameters. The results of the antenna measurements carried out in the anechoic chamber did not have a significant effect on the vswr parameters, return loss, bandwidth and impedance. Radiation pattern, polarization, gain, and other antenna parameters related to radiation in free space are the right parameters to be measured in the anechoic chamber. Keywords :Microstrip, Bending, Return Loss, VSWR, Bandwidth, Impedance, Anechoic Chamber
