Abstract

Noise pollution can come from various sources around us, such as loudspeakers. In Indonesia, where the majority of the population is Muslim, many mosques use loudspeakers to broadcast the adhan, or call to prayer. Recently, the use of mosque loudspeakers has sparked debate, as some people are concerned that the noise may disrupt their comfort and potentially affect their health. This study aims to assess whether the noise level of the adhan from these loudspeakers is within safe limits or exceeds the threshold that could harm human health. The research involved measuring the sound intensity of the adhan using a sound level meter app. Measurements were taken at two locations: within the mosque courtyard and at a distance of 100 meters from the mosque. The study examined six mosques in Bekasi City, with two mosques located in residential areas, two in office areas, and two in school areas. The results indicate that the highest noise levels were recorded in the mosque courtyards, with levels decreasing as the distance from the mosque increased. Among the six mosques, the highest noise level recorded was 84.5 dB in the mosque courtyard, which is below the threshold set by the Ministry of Manpower Regulation No. 5 of 2018, meaning it is still considered safe for human health

Abstract

SSVEP-based Brain-Computer Interfaces (BCIs) utilize steady-state visual evoked potentials, which are brain responses triggered by visual stimuli flickering at specific frequencies. Users can focus on these stimuli, allowing the system to interpret their intent based on the brain's electrical activity. This technology has applications in communication for individuals with disabilities, gaming, and neuro-feedback, offering an ultimate means of interaction through thought alone. In this study, systematic literature review was conducted to identify analytical methods for SSVEP spellers with PRISMA method from the eligibility criteria. CCA and its extension become gold-standar method that give excellent performances for SSVEP recognition and signal classification. Some uniques features also found such as MsetCCA, FB-CCA, MF-CCA, TW-CCA, CP-CCA, IIS-CCA, TT-CCA and RLS-CCA. Therefore, we have various options for choosing the best method for recognizing SSVEP from EEG signals based BCI.

Abstract

Kabupaten Subang memiliki potensi besar dalam sektor pertanian, namun petani lokal masih menghadapi kendala biaya produksi akibat mahalnya pupuk kimia. Kegiatan pengabdian ini bermitra dengan Kelompok Tani Rumah Petani Nelayan Nusantara (RPNN) di Kelurahan Cigadung, Subang, untuk memberikan solusi inovatif melalui pemanfaatan limbah kulit telur sebagai bahan dasar pupuk kalsium. Limbah ini banyak dihasilkan oleh rumah tangga dan UMKM kuliner, namun belum dimanfaatkan secara optimal, padahal mengandung lebih dari 90% CaCO₃ yang bermanfaat bagi tanah. Program dilaksanakan selama dua hari dalam lima tahapan: sosialisasi, pelatihan (seminar dan praktik), penerapan teknologi sederhana, pendampingan dan evaluasi, serta perencanaan keberlanjutan. Delapan peserta mengikuti pelatihan dan menunjukkan peningkatan pengetahuan tentang pupuk kalsium, perbedaan pupuk organik dan anorganik, serta potensi limbah lokal. 87,5% peserta menyatakan tertarik mengaplikasikan pupuk ini, dan seluruhnya percaya dapat menekan biaya produksi. Edukasi berbasis praktik terbukti efektif dalam meningkatkan kesadaran dan motivasi petani terhadap inovasi berbasis limbah.
