Human resources or labor was instrumental in the company. The purpose of this study was to analyze the relationship between age, working hours, job demand and job control with job stress on the staff of PT. Adhi Karya (Persero) Tbk. Hotel Grandhika SemarangDevelopment Project. This type of research is a kind of analytic survey research with cross sectional study. The population of the research is the staff of PT. Adhi Karya (Persero) Tbk. Hotel Grandhika Semarang Development Project totaling 40 people. The sample in this study were drawn from the total population. Work stress was measured using the Live Event Scale. Statistical analysis using Rank Spearman correlation test. The results showed there is no correlation between age (sig = 0.846), job demand (sig = 0.425), and job control (sig = 0.475) with work stress. There is a correlation between working hours (sig = 0.037) with work stress. Companies should consider the overtime rules set by the government to avoid fatigue due to working hours are too long, holding regular exercise to maintain fitness, and assign tasks according to expertise of workers in order to reduce the risk of work stress.

Abstract

Limbah cair peternakan sapi yang kaya urea, berpotensi menyebabkan pencemaran lingkungan seperti eutrofikasi dan peningkatan amonia yang berbahaya bagi lingkungan perairan. Penelitian yang dilakukan pada Desember 2024–Februari 2025 di Laboratorium Mikrobiologi FMIPA, Universitas Lampung bertujuan mengisolasi dan mengidentifikasi bakteri ureolitik dari kolam aerasi IPAL. Riset ini menggunakan metode deskriptif kualitatif yaitu pengambilan sampel, isolasi, uji aktivitas urease, serta karakterisasi morfologi, mikroskopis, dan fisiologi. Isolat yang dihasilkan yaitu 6 isolat bakteri ureolitik yang mampu menghidrolisis urea. Isolat-isolat ini menunjukkan morfologi koloni beragam seperti irregular, circular, elevasi flat dan umbonate; warna putih dan krem; tepi undulate, lobate, dan entire. Secara mikroskopis, sel berbentuk basil, coccus, dan coccobacil, semuanya Gram-positif. Tiga isolat CLR9.3, CLR9.4, CLR15.4 membentuk spora. Secara fisiologi, keenam isolat positif katalase dan mampu memfermentasikan sukrosa, maltosa, dan glukosa kecuali CLR9.3 dan CLR9.4 untuk laktosa dan CLR9.3 untuk manitol. Mayoritas isolat bersifat motil, kecuali CLR9.1 dan CLR9.3.
