The Influence of Alpha Waves in Cultural Arts (Music) Learning at Secondary School

Pendidikan musik, seperti yang dirasakan oleh para siswa, terutama berkisar pada aspek-aspek praktis, sering kali mengabaikan dimensi kognitif, afektif, dan psikomotorik yang melekat dalam pendidikan. Akibatnya, aspek kognitif dari pendidikan musik cenderung kurang menarik bagi siswa. Sebagai tanggapan, berbagai upaya telah dilakukan untuk merangsang konsentrasi kognitif siswa selama aspek teori pendidikan musik dengan memanfaatkan gelombang alpha. Gelombang alpha ini diintegrasikan selama pelajaran teori musik dan disajikan dalam bentuk video yang diunggah ke YouTube agar dapat diakses kapan saja dan di mana saja.Artikel ini bertujuan untuk menyelidiki dampak dari penggunaan YouTube sebagai media, dikombinasikan dengan musik latar yang mengandung frekuensi gelombang alpha, terhadap aspek teoritis pendidikan Seni Budaya (mus-ik). Penelitian ini menggunakan metode kuantitatif untuk mengkorelasikan kinerja antara kelompok kontrol (tidak terpapar gelombang alpha) dan kelompok eksperi-men (mengalami stimulasi gelombang alpha). Data dikumpulkan melalui penilaian yang dilakukan oleh guru Seni Budaya dan kemudian dianalisis dengan menggunakan teknik korelasi Pearson sebagai bentuk analisis data. Setelah meninjau hasil dari sampel pertama (kelompok eksperimen) dan sampel kedua (kelompok kontrol), terlihat jelas bahwa hipotesis akhir (hasilnya) tidak sesuai dengan hipotesis awal (H0 > Ha)

Analisis Pengukuran Waktu Baku Untuk Menentukan Tingkat Produktivitas Pada Operator Pemasangan O-Ring Menggunakan Metode Jam Henti (Studi Kasus Di PT Y)

With the development of the era of globalization and technological progress, the development of a manufacturer must also increase. One way to increase labour productivity is to calculate standard time. The standard time is the time required reasonably by a normal worker to complete a job that is carried out in the best work system. The research was carried out by direct observation in the field. Observation of the standard time that occurs through a certain time interval is useful for knowing the description of the use of queues. In this study, the population was operators working at PT Y at the time of the study, while the sample used was the total time of O-Ring installation. The analysis method used in this study uses the standard time analysis method using a stopwatch. Adjustments are made as a measuring effort to normalize the average price carried out by the operator. Adjustments are taken into account because operators in the work can do inappropriately, for example too fast as if in a hurry, encounter some difficulties, and other things. Time data collection was carried out 30 times by breaking down the work into three motion elements. The results of the standard time measurement for each motion element are motion element A of 65.125 seconds, motion element B of 463.84 seconds and motion element C of 59.66 seconds.
