Abstract

Di era saat ini, perkembangan teknologi sangat pesat, termasuk di bidang pariwisata. Salah satu hal utama yang menjadi perhatian di bidang pariwisata adalah kenyamanan pengunjung, yang dipengaruhi oleh faktor keamanan, terutama keamanan anak-anak. Masalah yang sering terjadi adalah terpisahnya anak dengan keluarganya di tengah keramaian pengunjung pariwisata. Sistem monitoring yang dapat memantau posisi anak-anak merupakan solusi dari permasalahan ini. Sistem monitoring yang diajukan menggunakan metode wireless network clustering dan terdiri dari perangkat statis node, mobile node danserver. Mobile node merupakan perangkat yang dibawa oleh pengunjung anak-anak yang berfungsi mengirimkan data posisi secara realtime ke statis node menggunakan modul transmisi RF HC-12, sedangkan statis node berfungsi sebagai penangkap pancaran dari mobile node, yang kemudian mengirimkan data pada server untuk kemudian ditampilkan di perangkat android yang dibawa oleh orang tua atau keluarganya. Hasil pengujian menunjukkan bahwa data dapat dikirim dengan optimal ketika pengaturan RF HC-12 menggunakan daya transmisi 20 dBm dan posisi antenna spring vertikal. Statis node dipasang dengan jarak 15 meter satu sama lain, sesuai dengan radius maksimal pengiriman data RF HC-12. Akurasi yang didapat mencapai 92% dengan 1000 kali percobaan pengiriman data.

Abstract

Super intensive shrimp pond wastewater with a stocking density of 750-1,250 individuals/m2 contains an average total suspended solids (TSS) of 798-924 mg/L, dissolved organic matter (BOT) of 81,227-88,641 mg/L; total nitrogen (TN) 9.8389-14.4260 mg/L; and total phosphate (TP) 7.8770-11.8720 mg/L. This value has exceeded the threshold limit of the permissible pond wastewater standard so it has the potential to hurt the environmental quality of water bodies receiving the waste load. making a more intensive vannamei shrimp farming pond cleaning system using turbidity sensors to read turbidity in shrimp farming ponds and ultrasonic sensors as readers of the water level in shrimp farming ponds and using a camera to detect the presence of foam waste in shrimp farming ponds and the Raspberry Pi microcontroller as a center system control on control devices and monitoring of all sensors then the output data will activate the drainage of leftover shrimp feed and shrimp waste from drainage to disposal using PVC pipes and automatic faucets that are driven using DC power window motors. The Internet of Things (IoT) automatic system in the construction of a waste cleaning device for shrimp ponds was built using a turbidity sensor that can detect the level of turbidity in water with an accuracy of 0.51%. The need for additional water in the pond is assisted by an ultrasonic sensor which provides information to the water pump with an average accuracy of 0.56%. To detect foam waste using a webcam camera as a foam detector.

Abstract

Hotel is a company that provides accommodation services and provides other facilities that meet the requirements of comfort and commercial purposes. The development of the times and technology, also affects the development of the hotel. The use of hotel reservation technology makes it easier for the hotel booking process. Service quality, trustworthiness, facilities and security affect hotel selection decisions. A common application of security technology is the use of duplicable RFID card lock technology. For this reason, it is necessary to add a double security system in the form of an OTP (One Time Password) code and limit access to visitors and visitors from visitors. The test results using NFC PN532 to read e-KTP cards obtained readings in under 1.00 seconds, with 100% accuracy within a distance of 0 - 2.5 cm. In testing with an additional OTP (One Time Password) code, the results obtained are good accuracy readings with an accuracy rate of 100% when the OTP code is appropriate.

Abstract

Pada penelitian ini dilakukan analisis performansi downlink LTE dan 5G dengan menggunakan MATLAB. Penelitian ini bertujuan untuk menganalisis perbandingan kinerja teknik modulasi QPSK, 16-QAM, dan 64-QAM yang digunakan pada downlink LTE dan teknik modulasi QPSK, 16-QAM, 64-QAM, dan 256-QAM pada downlink 5G yang melalui kanal AWGN untuk mengetahui nilai BER pada teknik modulasi yang digunakan. Teknik multiplexing yang digunakan adalah OFDM dan CP-OFDM untuk downlink LTE dan CP-OFDM untuk downlink 5G dengan variasi cyclic prefix yang digunakan adalah kategori ”normal”. Pada downlink LTE, kinerja modulasi QPSK lebih baik dari 16-QAM dan 64-QAM. Pada OFDM, BER QPSK diperoleh 10-19 pada Eb/No 16 dB, BER 16-QAM diperoleh 10-19 pada Eb/No 20 dB dan BER 64-QAM diperoleh 10-8 pada Eb/No 20 dB. Pada CP-OFDM, BER QPSK diperoleh 10-20 pada Eb/No 16 dB, BER 16-QAM diperoleh 10-19 pada Eb/No 20 dB dan BER 64-QAM diperoleh 10-9 pada Eb/No 20 dB. Pada downlink 5G CP-OFDM, kinerja modulasi QPSK lebih baik dari 16-QAM, 64-QAM dan 256-QAM, BER QPSK diperoleh 10-24 pada Eb/No 16 dB, BER 16-QAM diperoleh 10-23 pada Eb/No 20 dB, BER 64-QAM diperoleh 10-14 pada Eb/No 20 dB, dan BER 256-QAM diperoleh 10-7 pada Eb/No 20 dB.

Abstract

Mosques are one of the places where community activities are concentrated in the religious field, especially in Indonesia where the majority of the population is Moslems. The mosques are also important means of spreading religion, due to the close location and spread out in the community. The arrangement of the sound system in a mosque is one of the vital things to support religious activities. The purpose of this activity is to provide training on the installation and arrangement of sound systems at the Darul Muttaqin Mosque, Kedungkandang District, Malang. Training is given to mosque takmirs so that they can install and maintain sound systems in mosques. The result of this training was that the sound system of the mosque which was initially bad due to a buzzing sound and did not clearly convey the information provided became clearer and no longer disturbed the congregation or local residents. When there is a sound system problem, takmir can repair it directly without the need to wait for a technician so that religious activities and messages run smoothly.
