Abstract

ABSTRAKKemampuan pengubahan suara yang dilakukan Dubber untuk beragam bentuk suara menjadi perhatian khusus dengan melakukan rekayasa suara, di dalam perkembangan teknologi di kenal sebuah teknikpitch shifting yang digunakan untuk mengubah suara manusia di bagian timbre dan pitch. Penelitian ini menggunakan metodepitch shifting PSOLA (Pitch Synchronous Overlap Add) untuk merubah pitch sekaligus timbre suara. Proses yang dilakukan meliputi perekaman suara sehingga didapatkan sinyal suara. Sinyal hasil perekaman kemudian diolah untuk menemukan posisi pitch dari sinyal pada domain waktu. Setelah posisi pitch diketahui, jarak antar pitch akan dikalikan dengan bilangan skala pergeseran yang sudah ditentukan. Hasil dari perkalian tersebut adalah perubahan pada pitch suara, sehingga menghasilkan suara yang lebih tinggi atau lebih rendah. Perubahan juga terjadi pada timbre sehingga menghasilkan karakter suara yang berbeda dengan suara aselinya.Hasil pengujian pitch dan timbre dengan menggunakan metode PSOLA menunjukkan keberhasilan mencapai 98% berdasarkan sinyal sinus.Kata kunci: Pitch, Timbre,Pitch Shifting, PSOLA.ABSTRACTThe ability of converts sound done in various forms of a dubber sound, becomes a special attention in doing an engineering design sound. In the development of technology the pitch of shifting know a technique that is used to turn the human voice in the timbre and  pitch. This study using methods  pitch  shifting psola (pitch synchronous overlap add) to change the pitch as well as the timbre sound. The process was about recording a sound so obtained up a noise. Recording signals then processed the results to find the position of the pitch signals on the domain of time. After the position of the pitch known, the distance between the pitch will be multiplied by the number of the scale of a shift that had been determined. The result of the multiplication of the sound is a change in pitch , so producing a higher or lower, Also happens to change the timbre that produces characters a different voice with the original sound. The examination result of pitch and timbre using PSOLA method shows the success as big as 98% for signal sinus examination.Keywords: Pitch, Timbre, Pitch Shifting, PSOLA.

Abstract

ABSTRAKHidroponik merupakan sistem pertanian yang menggunakan air sebagai media tanam sehingga tidak memerlukan media tanah ataupun area luas. Hidroponik memerlukan perlakuan khusus seperti menjaga kadar nutrisi dalam rentangnya sehingga penggunaan sistem kendali dapat mempermudah pemantauan dan pengaturan parameter. Sistem kendali yang digunakan adalah fuzzy logic mamdani dengan input offset kadar nutrisi dan level air, serta output durasi nyala motor pompa nutrisi dan air untuk mencapai set point yang dapat ditentukan melalui antarmuka berdasarkan database objek tanam atau slider manual. Hasil penelitian menunjukkan nilai keberhasilan sebesar 95,14% untuk kendali nutrisi dan 91,64% untuk kendali level air dalam mencapai set point, serta menghasilkan pertumbuhan tanaman yang lebih baik, dimana rata-rata penambahan tinggi antara sistem dengan dan tanpa kendali nutrisi memiliki perbedaan sebesar 1,96 cm.Kata kunci: sistem kendali, fuzzy logic, IoT, hidroponik, nutrisi ABSTRACTHydroponic is a farming system which uses water as planting media, so it is unnecessary to use soil nor consume wide area.

Abstract

This study aims to develop an automated anthropometric system based on machine vision, integrated into a medical cyber-physical system (MCPS), to measure human head circumference. Head circumference is a critical parameter in growth monitoring, particularly for detecting abnormalities such as microcephaly and macrocephaly, which can affect cognitive development and overall health. To address this challenge, the study proposed an anthropometric system that enabled automated, accurate, and contactless measurements, accessible in real-time by healthcare professionals. The system was designed using a machine vision approach, incorporating object detection technology and elliptical model-based perimeter estimation to determine head circumference noninvasively. A 1,920 × 1,080-pixel (1080p) camera operating at 30 fps with a 60° field of view was mounted on a three-axis motion mechanism driven by stepper motors to automatically capture frontal and side views of the head. The measurement process began with head detection and bounding box adjustment to obtain head width parameters. Euclidean distance was used for measurement, followed by elliptical geometry modeling to estimate head circumference. Experimental results showed the lowest error rate of 2.29% at a distance of 50 cm under 300 lux lighting conditions. Performance evaluation using a confusion matrix yielded an accuracy of 92.8%, precision of 100%, recall of 97.5%, and F score of 98.7%. The proposed system provides an effective solution for healthcare professionals to perform growth screening quickly, accurately, and safely. It also supports remote healthcare services, particularly in areas with limited access to medical facilities.

Abstract

Upaya mencapai efisiensi energi, perlu pengurangan penggunaan AC yang tidak efisien, mengakibatkan konsumsi energi tinggi dan emisi karbon. Beban termal adalah total panas yang harus dikeluarkan dari ruangan untuk mempertahankan suhu nyaman, termasuk beban kalor sensibel dan laten. Tujuan penelitian ini untuk menganalisis manajemen pengondisian suhu ruangan berdasarkan beban termal menggunakan sensor thermopile infrared array. Jenis penelitian merupakan studi literatur. Sistem otomatisasi berbasis kamera termal AMG8833 dengan resolusi 8x8 piksel dikembangkan untuk mendeteksi kondisi ruangan secara efisien. ESP32 digunakan sebagai mikrokontroler untuk mengolah data dari kamera termal dan mengubah set point suhu ruangan menggunakan IR Transmitter. Pengaturan suhu dilakukan dengan mengatur fan AC berdasarkan hukum konveksi, sehingga distribusi udara lebih efektif. Sistem ini dilengkapi antarmuka dan LCD untuk pemantauan real-time serta pengubahan suhu langsung. Pengujian menunjukkan bahwa sistem berhasil mengoptimalkan suhu dan kenyamanan termal dengan penghematan daya 0.365 kWh. Sistem ini tidak hanya mengurangi konsumsi daya dan emisi karbon, tetapi juga meningkatkan kenyamanan dan produktivitas penghuni ruangan.
