Abstract

Making musical instruments that accompany vocals in a song depends on the mood quality and the music composer’s creativity. The model created by other researchers has restrictions that include being limited to musical instrument digital interface files and relying on recurrent neural networks (RNN) or Transformers for the recursive generation of musical notes. This research offers the world’s first model capable of automatically generating musical instruments accompanying human vocal sounds. The model we created is divided into three types of sound input: short input, combed input, and frequency sound based on the discrete cosine transform (DCT). By combining the sequential models such as Autoencoder and gated recurrent unit (GRU) models, we will evaluate the performance of the resulting model in terms of loss and creativity. The best model has a performance evaluation that resulted in an average loss of 0.02993620155. The hearing test results from the sound output produced in the frequency range 0-1,600 Hertz can be heard clearly, and the tones are quite harmonious. The model has the potential to be further developed in future research in the field of sound processing.

Abstract

Most Indonesian social media users under the age of 25 use various words, which are now often referred to as slang, including abbreviations in communicating. Not only causes, but this variation also poses challenges for the natural language processing of Indonesian. The previous researchers tried to improve the Recurrent Neural Network to correct errors at the character level with an accuracy of 83.76%. This study aims to normalize abbreviated words in Indonesian into complete words using a Recurrent Neural Network in the form of Bidirected Long Short-Term Memory and Gated Recurrent Unit. The dataset is built with several weight confgurations from 3-Gram to 6-Gram consisting of words without vowels and complete words with vowels. Our model is the frst model in the world that tries to fnd incomplete Indonesian words, which eventually become fully lettered sentences with an accuracy of 97.44%.

Abstract

Masyarakat pesisir memiliki peran penting dalam pengelolaan sumber daya pesisir yang berkelanjutan. Namun, keterbatasan akses terhadap teknologi dan pengetahuan dalam pemetaan sumber daya pesisir sering menjadi kendala dalam pengambilan keputusan berbasis data. Penelitian ini bertujuan untuk memberdayakan masyarakat pesisir Desa Lontar, Kabupaten Serang, Banten, melalui peningkatan kemampuan teknik survei dan pemetaan potensi desa pesisir. Metode yang digunakan meliputi pelatihan teori dan praktik survei lapangan, penggunaan teknologi Global Positioning System (GPS), analisis citra satelit, serta pengolahan data spasial menggunakan Sistem Informasi Geografis (SIG). Hasil kegiatan menunjukkan bahwa peserta pelatihan, yang terdiri dari perangkat desa, nelayan, dan masyarakat pesisir, mengalami peningkatan pemahaman terhadap teknik survei dan pemetaan. Peta penggunaan lahan yang dihasilkan mencakup informasi tentang ekosistem mangrove, tambak, pemukiman, serta utilitas lainnya. Evaluasi pasca-pelatihan menunjukkan bahwa 85% peserta mampu menggunakan GPS dan perangkat lunak pemetaan secara mandiri. Hasil dari kegiatan ini tidak hanya memberikan gambaran mengenai teknik survei pemetaan, tetapi juga ikut membantu pemerintah khususnya melalui perangkat desa dalam hal upaya pengayaan/pembaruan data dan informasi guna pengelolaan wilayah pesisir secara berkelanjutan.

Abstract

Terumbu karang adalah ekosistem laut yang menyediakan rumah bagi sekitar 25% organisme laut. Beberapa dekade terakhir, penggunaan metode Underwater Photo Transect (UPT) untuk pemantauan terumbu karang semakin populer. Penelitian ini bertujuan untuk memantau kondisi terumbu karang di Pulau Dua, Pulau Tikus, Pulau Belanda, dan Pulau Dapur. Penelitian ini menggunakan software Coral Point Count with Excel extensions (CPCe), untuk meningkatkan efisiensi upaya pemantauan terumbu karang. Transek foto diambil dengan penyelaman scuba. Foto komunitas terumbu karang diambil setiap 1m di sepanjang garis transek sepanjang 50m. Sebanyak 30 sampel titik acak dipilih untuk setiap foto. Beberapa foto digabungkan dan untuk setiap titik dikodekan sesuai dengan kode masing-masing kategori, biota, dan substrat pada titik acak. Hasil penelitian menunjukkan kondisi terumbu karang di Bengkulu termasuk dalam kategori sedang hingga baik, sedangkan kondisi terumbu karang di Kepulauan Seribu termasuk dalam kategori buruk hingga. Genus karang yang paling banyak ditemukan di Bengkulu adalah Porites dan Pocillopora, sedangkan di Kepulauan Seribu adalah Porites dan Acropora.

Abstract

Indonesia boasts a diverse range of indigenous scripts, called Nusantara scripts, which encompass Bali, Batak, Bugis, Javanese, Kawi, Kerinci, Lampung, Pallava, Rejang, and Sundanese scripts. However, prevailing character detection techniques predominantly cater to Latin or Chinese scripts. In an extension of our prior work, which concentrated on the classification of script types and character recognition within Nusantara script systems, this study advances our research by integrating object detection techniques, employing the YOLOv5 model, and enhancing performance through the incorporation of the U-Net model to facilitate the pinpointing of fundamental Nusantara script's character locations within input document images. Subsequently, our investigation delves into rearranging these character positions in alignment with the distinctive styles of Nusantara scripts. Experimental results reveal YOLOv5's performance, yielding a loss rate of approximately 0.05 in character location detection. Concurrently, the U-Net model exhibits an accuracy ranging from 75% to 90% for predicting character regions. While YOLOv5 may not achieve flawless detection of all Nusantara scripts, integrating the U-Net model significantly enhances the detection rate by 1.2%.
