"BTS, grup musik asal Korea Selatan yang debut pada Juni 2013 dibawah Big Hit Entertainment telah meraih ketenaran global dengan mengeksplorasi berbagai genre, tradisi musik, dan budaya. Kemudian terjadilah perdebatan seputar identitas genre BTS. Berdasarkan hal ini, timbul pertanyaan mengenai sejauh mana BTS dapat dipahami dalam ruang kategorisasi genre? Penulis melihat bahwa ada "kekacauan" dalam kategorisasi genre. Untuk menganalisis ini, penulis menggunakan dua metode penelitian, pertama, metode eksperimentasi pemikiran, yaitu menguji kebenaran adanya "kekacauan" kategorisasi genre mengenai esensi K-pop dan validitas penempatan BTS dalam genre tersebut. Kedua, metode analisis filosofis komparatif dengan membandingkan dialektika Hegel dengan kategorisasi, ditambah dengan kontra-argumennya, sehingga memicu refleksi filosofis yang kritis terhadap BTS dan hakikat kategorisasi itu sendiri, dimana dapat menunjukkan “cairnya” kategorisasi genre. Dialektika Hegel dan kategorisasi genre menjadi kerangka teori utama, dan topik K-pop menjadi teori pendukung dalam analisis ini. Melalui metode dan kerangka teori tersebut, akan dipahami bahwa makna BTS dan kategorisasi genre akan lebih filosofis jika kita melihatnya melalui dialektika Hegel.

BTS, a South Korean music group that debuted in June 2013 under Big Hit Entertainment, has achieved global fame by exploring various genres, musical traditions, and cultures. This has sparked debates about BTS's genre identity, leading to questions about the extent to which BTS can be understood within the framework of genre categorization. The author observes a "chaos" in genre categorization and employs two research methods for analysis. First, thought experimentation examines the truth of the "chaos" in genre categorization regarding the essence of K-pop and the validity of placing BTS within that genre. Second, a comparative philosophical analysis, contrasting Hegelian dialectics with categorization and supplemented with counter-arguments, triggers critical philosophical reflection on BTS and the nature of categorization itself, indicating the “fluidity” of genre categorization. Hegelian dialectics and genre categorization serve as the primary theoretical framework, with K-pop providing supporting theory in this analysis. Through these methods and theoretical frameworks, it will be understood that the meaning of BTS and genre categorization becomes more philosophical when viewed through the lens of Hegelian dialectics."

"Singing is the most important element of the traditional music culture on Siberut, the largest of the Mentawai Islands (West Sumatra, Indonesia). There are various types of songs on the island. Some of them are related to the world of spirits and ancestors. These are mainly sung by shamans during healing ceremonies and rituals. Other songs are made up by men and women during their daily activities, when they are fishing out at sea or when they take a rest from collecting forest products. Various animals (birds, primates, reptiles) or natural forces (wind, thunder) provide inspiration for lyrics and melodies, as do special events, like the arrival of a logging company on the island). In this article, we discuss the process of recording the songs and other types of music of the island and the production of two CDs and the reactions of the singers and the community to the presentation of the CDs. In a context of decades of suppression of various aspects of the traditional culture (religion, tattoo, loincloth) documentation of a form of intangible culture and its positive appreciation can generate a sense of pride among a local community. In addition, we have added an extensive appendix to this article containing the lyrics of a number of songs in both the local language as well as in translation. It allows readers to get an idea of the poetic nature of the song literature of the Mentawaians."

"Kelapa kopyor merupakan kelapa yang mengalami kelainan genetik sehingga daging buahnya tidak menempel pada tempurung kelapa. Hal tersebut diakibatkan oleh defisiensi enzim ?-D-galaktosidase yang menyebabkan tekstur dari daging kelapa kopyor unik. Keunikan tersebut menjadikannya memiliki banyak peminat sehingga harganya lebih tinggi, mencapai 4-5 kali lipat dari harga kelapa biasa. Dari penampakan luarnya kelapa kopyor tidak berbeda dibanding kelapa biasa. Selama ini petani maupun penjual menggunakan cara tradisional dengan mendengarkan suara guncangan dari kelapa kopyor untuk membedakannya. Sayangnya, cara tersebut sangat bergantung pada pengalaman dan keterampilan dari pemilahnya. Maka dari itu, pada penelitian ini diajukan metode deteksi kelapa kopyor berbasis pengenalan suara menggunakan Mel Frequency Cepstrum Coefficient MFCC sebagai metode ekstraksi fitur suara dan Dynamic Time Warping DTW sebagai metode pencocokan fitur suara. Objek yang akan dideteksi adalah kelapa kopyor dan kelapa biasa yang sudah tua. Dengan menggunakan kedua metode tersebut, sebuah program telah dibuat untuk dapat mendeteksi kelapa kopyor dengan akurasi sebesar 96.4.

Kopyor coconut is a coconut that has genetic abnormalities which cause the coconut meat to not stick to the coconut shell. It is caused by deficiency of enzyme D galactosidase which causes the texture of kopyor coconut meat to become unique. Its uniqueness attracts many enthusiasts resulting in a high economic value, 4 5 times that of the ordinary coconut. From its external appearance, kopyor coconut does not differ with ordinary coconut. To date, both farmers and sellers use a traditional method by listening to the sound of whisk from kopyor coconut to detect them. Unfortunately, it relies heavily on experience and expertise of the person.

Therefore, a new detection method is proposed based on sound recognition using Mel Frequency Cepstrum Coefficient MFCC as the method for feature extraction and Dynamic Time Warping DTW as the method for feature matching. Objects that will be detected are kopyor coconuts and ordinary coconut which has grown mature. By using both methods, a program has been developed to detect kopyor coconut with an accuracy 96.4."

"Dengan kemajuan teknologi saat ini, perkembangan peralatan yang digunakan manusia dari segi informasi, komunikasi, produksi, transportasi, dan hiburan semakin pesat. Namun, sebagian besar peralatan ini menghasilkan suara yang tidak diinginkan, menyebabkan gangguan. Untuk mengatasi masalah ini, telah dikembangkan berbagai jenis bahan peredam suara. Meskipun kemajuan ini memberikan manfaat besar dalam meningkatkan efisiensi dan kenyamanan penggunaannya, tetapi juga memunculkan masalah baru terkait gangguan yang tidak diinginkan. Penelitian ini bertujuan untuk mengembangkan lembaran sandwich menggunakan SS Wire Mesh 8 sebagai inti dan SS 304 sebagai lapisan muka, dengan variasi filler glasswool dan rockwool untuk meningkatkan sifat mampu bentuk dan penyerapan suara. Evaluasi eksperimental dilakukan, termasuk pengujian regangan, perluasan lubang, regangan-bend, dan uji transmisi suara, untuk mengevaluasi sifat mampu bentuk komposit dan kemampuan peredam suaranya. Hasil penelitian menunjukkan peningkatan Batas Tinggi Kubah (LDH) sebesar 20,51% dan 8,46% dengan penggunaan filler rockwool dan glasswool, yang mengindikasikan peningkatan kemampuan regangan dari 3,90 mm menjadi 4,70 mm dan 4,23 mm, masing-masing. Rasio Ekspansi Lubang (HER) juga menunjukkan peningkatan signifikan sebesar 10,6% dan 19,6% untuk sampel dengan filler, dari 3,8%, karena pengaruh filler terhadap sifat penyerapan energi dan distribusi beban pada komposit sandwich. Namun, pengujian rentang tekuk menunjukkan bahwa peningkatan ketebalan sampel dengan filler menghasilkan Rasio Tekuk yang lebih rendah. Hasil pengujian pada sampel komponen peredam suara menunjukkan bahwa komposit sandwich dengan filler mampu menyerap suara lebih baik dibandingkan yang tanpa filler, dengan nilai kehilangan transmisi (TL) pada sampel filler glasswool dan rockwool masing-masing mencapai 4,41 dB dan 4,37 dB.

The rapid advancement of technology has led to the increased development of tools across various sectors including information, communication, production, transportation, and entertainment. However, many of these tools generate unwanted noise, causing disturbances. To mitigate this issue, various sound-absorbing materials have been developed. While these technological advancements have significantly enhanced human efficiency and comfort, they have also introduced challenges related to unwanted disturbances. This study focuses on the development of sandwich sheets using SS Wire Mesh 8 as the core and SS 304 as the face, incorporating variations of glasswool and rockwool fillers to improve sound formation and absorption properties. Experimental evaluations included stretching, hole expansion, stretch-bend, and sound transmission tests were conducted to evaluate the formability and sound-damping characteristics of the composite. The findings revealed an increase in the Limiting Dome Height (LDH) by 20.51% and 8.46% with rockwool and glasswool fillers, respectively, indicating enhanced strain capacity from 3.90 mm to 4.70 mm and 4.23 mm, respectively. The Hole Expansion Ratio (HER) exhibited a notable increase of 10.6% and 19.6% for samples with fillers, compared to 3.8% without fillers, demonstrating the fillers' impact on energy absorption and load distribution in the sandwich composite. However, the stretch-bend tests indicated that increased sample thickness with fillers resulted in a lower Bend Ratio. Sound absorption tests on the composite samples for sound-damping components indicated superior performance of sandwich composites with fillers compared to those without fillers, achieving transmission loss (TL) values of 4.41 dB and 4.37 dB for glasswool and rockwool fillers, respectively."
