Abstract

Permasalahan limbah organik rumah tangga dan pasar tradisional yang tidak terkelola dengan baik dapat menimbulkan dampak negatif terhadap lingkungan. Salah satu solusi pemanfaatan limbah tersebut adalah melalui produksi pupuk organik cair (POC) yang ramah lingkungan. Penelitian ini bertujuan untuk mengevaluasi efektivitas pupuk organik cair yang dibuat dari kombinasi limbah sayuran, kulit nanas, dan air cucian beras dengan penambahan Effective Microorganisme 4 (EM4) terhadap pertumbuhan tanaman sawi manis (Brassica juncea L.). Penelitian dilaksanakan secara eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari empat perlakuan dosis POC: 0 ml (kontrol), 5 ml, 10 ml, dan 15 ml per 250 ml air, masing-masing dengan empat ulangan. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, lebar daun, dan berat basah tanaman. Hasil penelitian menunjukkan bahwa pemberian POC secara signifikan meningkatkan pertumbuhan sawi manis pada semua parameter dibandingkan kontrol, dengan dosis optimal sebesar 15 ml POC+250 ml air. Kandungan hara makro POC, khususnya kalium (0,96%), serta kontribusi bioaktif dari bahan organik dan EM4, berperan dalam merangsang pertumbuhan vegetatif tanaman. Temuan ini menunjukkan bahwa pemanfaatan limbah organik menjadi POC tidak hanya mendukung pertanian berkelanjutan, tetapi juga menawarkan alternatif efektif dalam pengelolaan sampah organik

Abstract

Street food remains a popular choice for students due to its affordability and convenience. Its rapid preparation and service contribute to its ongoing popularity. The university, including Universitas Negeri Medan, is often surrounded by numerous street vendors offering a diverse range of foods, predominantly made from meat and flour. However, the open exposure of these foods and insufficient sanitation practices pose a heightened risk of contamination by harmful microorganisms. This study examines bacterial contamination in processed meat-based street foods sold near Universitas Negeri Medan, with a focus on items such as meatballs, grilled meatballs, and batagor. Microbiological examination involved isolating bacteria using selective and differential culture media, particularly Eosin Methylene Blue Agar (EMBA). Subsequent identification was carried out using Gram staining to determine cell morphology and SIM (Sulfide Indole Motility) medium for motility assessment in the microbiology lab at Universitas Negeri Medan. Findings revealed contamination predominantly in grilled meatballs, with bacteria belonging to the Enterobacteriaceae family detected. These isolates were characterized as Gram-negative, rod-shaped, and motile microorganisms. The presence of such bacteria raises serious concerns about food safety. It emphasizes the need for improved hygienic practices and rigorous food safety control measures in street food vending areas around the university. Implementing these measures is essential to safeguard student health and maintain the standard of street food quality on campus.
