Abstract

Jembatan Precast Prestress merupakan jembatan yang terbuat dari perpaduan antara Beton dan Baja Prategang yang sudah mengalami tegangan internal dengan besar (akibat stressing) dan distribusi sedemikian rupa sehingga dapat mengimbangi sampai batas tertentu tegangan yang terjadi akibat beban eksternal.Desa Betapus Bayur termasuk kedalam salah satu kelurahan di kecamatan Samarinda Utara, Kota Samarinda, Provinsi Kalimantan Timur, Indonesia. Kelurahan Sempaja Selatan berbatasan dengan wilayah Utara yaitu SempajaTimur, wilayah Selatan berbatasan dengan kelurahan Gunung Kelua Samarinda Ulu, wilayah Barat berbatasan dengan kelurahan Gunung Kelua Samarinda Ulu dan wilayah Timur berbatasan dengan Sungai Karang Mumus.Analisa perhitungan jembatan precast prestress menggunakan peraturan RSNI T-02-2005 tentang pembebanan pada jembatan. Tinjauan perhitungan meliputi perhitungan tiang sandaran, trotoar, pelat injak, lantai kendaraan, PCI girder, abutment, wing wall, dan pondasi tiang pancang.                                                                                                                                                         Dari proses analisa diperoleh kesimpulan bahwa kebutuhan penulangan masing-masing elemen struktur berbeda-beda, kebutuhan tulangan mulai dari diameter 10mm, 12mm, 13mm, 16mm, 19mm, dan 22mm. Baja prategang yang digunakan pada PCI  girder adalah 7 wire super standar ASTM A-4 16 grade 270. Untuk pondasi tiang pancang digunakan diameter 50cm, kedalaman 24 meter dan 22 meter dalam keadaan End Bearing, serta dibutuhkan masing-masing 24 buah titik pancang.

Abstract

This study aims to analyze the relationship between brainwave activity and the learning readiness of students with disabilities by utilizing EEG (Electroencephalography) signals. EEG signals are used to detect the brain's electrical activity that reflects mental states, including focus, concentration, and readiness to receive learning. This study was conducted at SLB 'Aisyiyah Krian with a quantitative approach through EEG signal measurement before and during the learning process. The results showed a significant correlation between the dominance of alpha and beta waves with learning readiness, while the dominance of theta and delta waves indicated unpreparedness. These findings provide a foundation for the development of a more inclusive, objective, and adaptive neurotechnology-based learning approach for students with disabilities.

Abstract

Kuala Trang in Nagan Raya Regency has significant coastal natural tourism potential, but it has not been optimally utilized for community welfare. This study aims to analyze local resource-based community empowerment strategies to develop a sustainable tourism village. The research method uses qualitative and quantitative approaches to examine supply (through observation and interviews) and demand (through questionnaires of potential tourists). The results show that although the community is very supportive (86%) and the natural scenery is very potential (score 3.86), this destination has critical weaknesses in the institutional aspects (score 1.07), amenities, active attractions, and promotion. Therefore, an integrative empowerment model is formulated that synergizes institutional strengthening (Pokdarwis), community capacity development, the creation of experience-based tourism packages, and digital marketing. The strategic implications emphasize multi-stakeholder collaboration, where the village and district governments act as facilitators and regulators, while the community acts as the main organized actor to create sustainable and equitable tourism.
