Abstract

Background: Accountability structures governing personnel attendance in Indonesian higher education demand audit-compliant records. Paper-based registers in mid-tier private universities suffer from proxy signing, retroactive logs, physical record loss, and manual entry overhead. Objective: This study presents the design, longitudinal evaluation, and operational stress-testing of UNES Hebat, a zero-hardware cloud-native GPS attendance platform deployed at Universitas Ekasakti in Padang, West Sumatra, Indonesia. Methods: The system features Progressive Web Application clients, edge content delivery, managed cloud databases, and a three-layer verification engine (Haversine GPS geofencing, real-time photographic auditing, and server-authoritative temporal validation via database stored procedures). Performance was tracked across 181 operational days with 288 registered staff, followed by a five-day stress event with 849 student participants. Results: The platform processed 29,251 attendance records with a 99.92% present-status rate and zero downtime across 4,344 server-hours. During the five-day orientation event, the platform absorbed a nineteen-fold concurrent-user surge without infrastructure modifications or performance loss. Conclusion: Server-authoritative validation paired with managed cloud architecture provides a resilient, cost-effective model for university digital governance.

Abstract

Penelitian dalam bentuk percobaan dengan judul formulasi pupuk kandang sapi dan guano pada media pembibitan kelapa sawit (Elaeis guineensis Jacq) di main nursery telah dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Ekasakti Padang. Pelaksanaan dari bulan Februari 2022 sampai Mei 2022. Tujuan penelitian untuk mendapatkan Formulasi Pupuk Kandang Sapi dan Guano yang terbaik pada Media Pembibitan Kelapa Sawit (Elaeis guineensis Jacq.) di main-nursery. Percobaan menggunakan Rancangan Acak Kelompok dengan 5 perlakuan 5 kelompok. Masing-masing satuan percobaan terdiri dari 3 bibit, semua bibit diamati. Formulasi sebagai berikut A = (4,8 kg pupuk kandang sapi + 100g guano)/polibag; B= (4,2 kg pupuk kandang sapi + 200 g guano)/polybag; C = (3,6 kg pupuk kandang sapi + 300 g guano)/polibag; D = (3,0 kg pupuk kandang sapi+400 g guano)/polibag dan E = (2,4 kg pupuk kandang sapi + 500 g guano)/polibag. Data hasil pengamatan dianalisis secara statistik dengan uji F dan pengujian lanjutan dengan Duncan’s New Multiple Range Test (DNMRT) pada taraf 5%. Hasil percobaan memperlihatkan pengaruh formulasi yang berbeda nyata terhadap variabel pengamatan yaitu: pertambahan tinggi bibit, pertambahan diameter bonggol, bobot segar bagian atas, bobot kering bagian atas, bobot segar bagian akar, bobot kering bagian akar, pertambahan jumlah daun. Formulasi 2,4 kg pupuk kandang sapi + 500 g guano (perlakuan E) merupakan kombinasi yang terbaik terhadap pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq.) di Main-Nursery. Disarankan untuk menggunakan formulasi 2,4 kg pupuk kandang sapi + 500 g guano untuk pembibitan kelapa sawit (Elaeis guineensis Jacq.) di Main-Nursery.
