Abstract

IEEE 802.11n technology comes with many advantages such as high data rate and reliability. In 2,4 GHz and 20 MHz bandwidth, it gives data rate up to 300 Mbps. In order to improve reliability without complexity, it uses STBC (Space Time Block Coding) using Alamouti algorithm. This algorithm can be implemented with many STBC scheme, i.e., 2x1, 2x2, 3x1, 3x2, 3x3, 4x1, 4x2, 4x3 and 4x4 using BPSK, QPSK, 16-QAM and 64-QAM modulation. Impulse respons of (Laboratorium Telekomunikasi Radio dan Gelombang Mikro) LTRGM indoor channel can be modeled by using ray tracing method. This simulation also investigates the effect of MIMO channel corelation caused by channel fading and physical antenna factor. The results, LTRGM indoor channel give delay spread and rms delay of 71.94 ns and 1.5 ns respectively. The ergodic channel capacity declines steadily as the channel correlation becomes worse. This problem also cause a decrease in SNR performance to achieve SER of 10-3 with various modulation. However, this does not have significant influence on WLAN system that uses STBC with four both transmit and receive antenna

Abstract

Metode pembelajaran daring menjadi kebutuhan mendasar dalam proses pembelajaran di berbagai mata kuliah yang diajarkan selama kondisi pandemi saat ini. Teknologi Mitigasi Bencana merupakan salah satu mata kuliah pilihan Program Studi Teknik Elektro yang menggunakan proyek berbasis kelompok sebagai salah satu tugas perkuliahan semester genap 2020/2021 ini. Poster desain sistem peringatan dini (early warning system, EWS) merupakan luaran wajib dari setiap kelompok yang terdiri dari lima orang. Selain kejelasan dalam pembagian tugas, keberagaman metode dalam proses pemantauan tugas dan peran ketua atau koordinator kelompok memiliki andil yang besar dalam mencapai target penyelesaian. Pemberian umpan-balik secara rutin dan penerapan lini-masa (timeline) merupakan faktor pendorong penting agar setiap kelompok memiliki frekuensi atau kecepatan yang sama. Selain dukungan modul pembelajaran dan video penerapan EWS, hadirnya pembicara tamu dalam perkuliahan beserta skenario pelaksanaannya dapat menambah wawasan nyata terhadap teknologi yang dibuat.

Abstract

Disaster occurrence in Indonesia needs attention and role from all parties including the community to reduce the risks.  Disaster mitigation is one of the ways to reduce the disaster risk through awareness, capacity building, and the development of physical facilities, for example by applying disaster mitigation technology (early warning system, EWS). EWS is one of the effective methods to minimize losses due to disasters by providing warning based on certain parameters for disasters which usually occur such as floods. This research promotes a real-time IoT-based EWS flood warning system (Flood Early Warning System, FEWS) using Arduino and Blynk as well as Global System for Mobile Communication network (GSM) as the communication medium. The steps for implementing FEWS system in real locations are also discussed in this paper. Parameters such as water level, temperature, and humidity as well as rain conditions that are read by the EWS sensor can be accessed in real-time by using android based Blynk application that has been created. The result of the measurement of average temperature, humidity, and water level were 28.6 oC, 63.7 %, and 54.5 cm. Based on this analysis, the parameters indicated that the water level is in normal condition and there are no signs indicating that there will be flooding in the 30 days observation.  Based on the data collected by the sensor, FEWS can report four conditions, namely Normal, Waspada Banjir (Advisory), Siaga Banjir (Watch), and Awas Banjir (Warning) that will be sent immediately to the Blynk FEWS application user that has been created.

Abstract

Kerusakan lampu lalu lintas dapat menjadi penyebab utama kemacetan di persimpangan jalan Ketidakpedulian masyarakat dan lambatnya penanganan kerusakan lampu oleh petugas dapat memperburuk situasi di tengah kepadatan jalan dan bahkan dapat menyebabkan kecelakaan. Sistem monitoring kondisi lampu lalu lintas berbasis Internet-of-Things (IoT) diusulkan untuk memberikan solusi terhadap permasalahan tersebut. Pemantauan kondisi lampu dan notifikasi secara langsung kepada petugas terkait, dalam hal ini Dinas Perhubungan, baik melalui Short-Message-Service (SMS) maupun aplikasi Blynk dapat mempercepat penanganan kerusakan lampu. Selain itu, parameter seperti arus, tegangan, dan daya dapat dipantau secara real-time sehingga tanda-tanda kerusakan dapat dideteksi lebih awal. Sistem ini menggunakan sensor arus PZEM004T yang terintegrasi dengan Arduino Mega. Selain itu, terdapat modul GPS yang berfungsi untuk memberikan informasi lokasi titik lampu lalu lintas yang dipantau. Hasil pengujian menunjukkan bahwa sistem montoring yang terdiri dari modul pengirim dan aplikasi penerima berfungsi dengan baik. Meskipun akurasi pengukuran arus belum mencapai 70%, akurasi pengukuran tegangan dan daya di atas 97%. Petugas mendapatkan notifikasi kerusakan secara langsung ketika lampu padam atau rusak. Implementasi sistem ini diharapkan dapat meningkatkan kecepatan penanganan kerusakan lampu lalu lintas dan sekaligus memudahkan dalam pengelolaan lampu lalu lintas sebagai fasilitas utama di jalan raya.

Abstract

This paper presents Martibo, a smart tissue dispensing management system integrated with a smartphone based on the Internet of Things (IoT), to improve tissue usage efficiency in public spaces and households. The system uses sensors to detect tissue availability and sends notifications to the Blynk application. The system is evaluated based on reliability, accuracy, and user interface responsiveness. The results show high accuracy with an average error of 0.91% in tissue availability detection and an average notification response time of 1.2 seconds. The system transmits data accurately through a Wi-Fi connection, enhancing the convenience and efficiency of tissue usage. The advantages of this system include accurate real-time data, a user-friendly interface, and good integration with mobile devices, making it an ideal solution for efficient tissue management.
