Praktik Kerja Lapangan (PKL) ini bertujuan untuk mempelajari secara komprehensif teknik dan manajemen penanganan pasca panen produksi benih jagung hibrida (Zea mays L.) di PT. Syngenta Seed Indonesia Pasuruan Site. Penanganan pasca panen merupakan salah satu tahapan krusial dalam menentukan kualitas akhir benih unggul serta meminimalisir potensi kehilangan hasil baik secara kuantitatif maupun kualitatif. Kegiatan operasi pasca panen yang dipelajari mencakup departemen Post Harvest Operation (PHO) yang mengelola alur pemrosesan primer material jagung yang baru dipanen dari lahan produksi. Rangkaian proses utama PHO terdiri atas penimbangan (weighing bridge), penerimaan hasil panen (receiving), pemilihan (sortasi), dan pengeringan (drying). Proses penerimaan memastikan logistik jagung dari lapangan dikelompokkan berdasarkan varietas hibridanya untuk menjaga kemurnian genetik. Tahapan sortasi dilakukan secara manual di atas konveyor untuk memisahkan tongkol jagung berkualitas dari kriteria reject seperti off-type, bad fill, disease, cobs premature, fungus, dan tipe male. Selanjutnya, tongkol jagung terpilih dikeringkan di dalam fasilitas Bin Dryer menggunakan metode konveksi udara panas dari bahan bakar gas. Proses pengeringan diaplikasikan melalui sistem pengaturan aliran udara (Up Air dan Down Air) selama kurang lebih 110 hingga 129 jam untuk menurunkan kadar air secara bertahap dari kisaran awal 25-35% menuju target kadar air aman simpan sebesar 10,3-10,7%. Pengelolaan operasional yang efisien dan terstandar pada fase PHO terbukti mampu mencegah kerusakan biologis akibat infeksi cendawan kontaminan serta menjaga integritas fisik serta viabilitas benih jagung hibrida demi mendukung produktivitas pertanian nasional.


Deskripsi Lain

This Field Work Practice (PKL) aimed to comprehensively study the techniques and management of post-harvest handling in hybrid corn (Zea mays L.) seed production at PT. Syngenta Seed Indonesia Pasuruan Site. Post-harvest handling is a crucial stage in determining the final quality of superior seeds and minimizing potential quantitative and qualitative crop losses. The post-harvest operations observed included the Post Harvest Operation (PHO) department, which manages the primary processing flow of freshly harvested corn from production fields. The main components of the PHO process consist of weighing (weighing bridge), reception (receiving), selection (sorting), and drying. The receiving process ensures that corn logistics from the field are grouped by hybrid variety to maintain genetic purity. The sorting stage is carried out manually on conveyors to separate high-quality corn cobs from rejected criteria such off-type, bad fill, disease, premature cobs, fungus, and male types. Subsequently, the selected corn cobs are dried in Bin Dryer facilities using the hot air convection method fueled by gas. The drying process is applied through regulated airflow configurations (Up Air and Down Air) for approximately 110 to 129 hours to gradually reduce the moisture content from an initial range of 25-35% to a safe storage target of 10.3-10.7%. Standardized and efficient operational management during the PHO phase is proven to prevent biological damage caused by contaminant fungal infections and to preserve the physical integrity and viability of hybrid corn seeds to support national agricultural productivity.
