Fawwaz Mulya Rabbani Fawwaz — 2024-06-19

Around 90% of Indonesia's population uses rice as food. However, the production process has not been able to fully fulfil the needs of the community, due to several obstacles that affect productivity. Bird pests are one of the main causes of rice disruption. Group birds are known as one of the few pests that tend to cause population problems. The purpose of this research is to get the design of an IoT-based rice bird repellent. This IoT-based bird repellent consists of two main parts: hardware, or hard system, and software, or soft system. An ESP32 microcontroller and ultrasonic sensors are used in this prototype. This Bird Pest Prototype can be hammered automatically. As a result, the existence of this prototype makes it easier for caregivers to treat patient wounds in case of pest injuries; however, this can be done more effectively and efficiently because caregivers do not need to visit the fields to treat patient wounds due to various pest injuries. Based on this prototype, if the ultrasonic sensor detects a bird with a range of 0 to 4 metres, the buzzer will sound, and the servo motor will move the lever to bring the radar-detected bird closer.

Analisa Metode Pengalokasian Time Slot pada Jaringan Time Division Duplex

Rini Astuti — 2025-01-11

Perkembangan komunikasi bergerak sudah sangat maju teknologi. Tujuan perkembangan jaringan komunikasi bergerak adalah menyediakan standar yang dapat memenuhi aplikasi-aplikasi nirkabel yang luas variasinya, tidak hanya mampu menyediakan jenis layanan dasar seperti suara (voice) dan pesan (messaging) saja melainkan telah diperluas hingga mampu menyediakan jenis layanan multimedia dan high multimedia. Salah satu karakter layanan multimedia dan high multimedia adalah sifat keasimetrisan dari sisi trafiknya, sehingga kebutuhan data rate pada arah downlink berbeda dengan kebutuhan data rate pada arah uplink. Hal ini dapat menyebabkan ketidakefisienan penggunaan bandwitdh apabila diimplementasikan dengan menggunakan sistem FDD, untuk hal tersebut maka UMTS juga mengeluarkan standard TDD dimana pada sistem ini alokasi time slot antara uplink dan downlink dapat diatur sehingga sistem dapat mencapai kondisi optimal. Pengalokasian time slot antara uplink dan downlink yang optimal disimulasikan dengan metode alokasi time slot seragam (uniform allocation) dan metode alokasi time slot tak-seragam (non-uniform allocation). Masing-masing formulasi kedua metode alokasi time slot tersebut diselesaikan dengan metode optimasi simpleks. Dari hasil simulasi tersebut terlihat bahwa metode uniform allocation sesuai untuk jenis trafik simetris dan komposisi trafik antar sel yang seragam, sedangkan metode non-uniform allocation sesuai untuk jenis trafik asimetris dengan tingkat keasimetrisan yang tinggi. Pada kondisi rasio interferensi yang tinggi maka metode non-uniform memiliki tingkat ketahanan kapasitas yang lebih baik dibandingkan metode uniform.
