Publisher : Universitas Sumatera Utara

Teknik kriopreservasi merupakan teknik yang potensial untuk penyimpanan plasma nutfah jangka panjang, yaitu menyimpan tanaman ke dalam nitrogen cair yang bersuhu -196ºC. Benih yang telah matang fisiologis memiliki kadar air yang tinggi, apabila langsung di simpan di dalam nitrogen cair akan mengalami kerusakan karena suhu yang sangat dingin, agar tidak terjadi kerusakan perlu dicapai kadar air yang tepat dan diberi krioprotektan. Salah satu cara penurunan kadar air dapat dilakukan dengan pengeringan. Penelitian ini bertujuan untuk mengetahui pengaruh lama pengeringan dan lama perendaman dalam krioprotektan terhadap viabilitas benih rosella secara kriopreservasi. Penelitian ini dilaksanakan di Laboratorium Teknologi Benih Fakultas Pertanian Universitas Sumatera Utara Medan, menggunakan rancangan acak kelompok dengan 2 faktor perlakuan. Faktor pertama adalah lama pengeringan (0 jam; 24 jam; 48 jam; 72 jam; 96 jam) dan faktor kedua lama perendaman dalam krioprotektan (0 menit; 30 menit; 60 menit; 90 menit; 120 menit). Hasil penelitian menunjukkan bahwa lama pengeringan berpengaruh nyata terhadap kadar air benih, kecambah normal dan indeks vigor. Namun lama perendaman dalam krioprotektan tidak berpengaruh nyata terhadap kadar air benih, kecambah normal dan indeks vigor. Interaksi perlakuan tanpa pengeringan dengan perendaman dalam krioprotektan selama 30 menit dapat menurunkan kadar air 11, 81 %.

ABSTRAKDusun Soporaru merupakan salah satu dusun di Sumatera Utara yang memiliki beras spesifik lokal yaitu beras Natabo, yang merupakan beras super lokal milik petani sekitar dan sudah resmi dipasarkan. Namun, hingga saat ini infrastruktur bidang pertanian yang mendukung masih kurang memadai, seperti kebiasaan masyarakat dalam menggunakan bahan kimia untuk mengendalikan hama penyakit tanaman serta jumlah alat mesin pertanian untuk pengolahan padi yang masih belum tercukupi. Kegiatan ini bertujuan untuk membuat petani di desa mitra mengetahui potensi sumber daya alam bidang pertanian yang ada, khususnya padi beras merah, menerapkan konsep pengendalian hama terpadu dan bimbingan teknis pascapanen padi menggunakan mesin huller agar petani dapat mengolah hasil panen secara mandiri dan tepat guna sehingga kualitas dan kuantitas beras merah dari desa mitra meningkat. Pada kegiatan ini, dilakukan sosialisasi dan focus group discussion (FGD) dengan petani desa mitra untuk membahas masalah yang ada di lapangan selama ini, selanjutnya petani dibimbing untuk melakukan pengendalian hama padi tanpa bahan kimia yaitu dengan menggunakan alat perangkap jaring (sweep net) dan bimbingan teknis penggunaan mesin huller untuk tahap pascapanen padi. Kegiatan pengabdian masyarakat baik pada saat sosialisasi, diskusi maupun bimbingan teknis di lapangan telah terlaksana dengan baik dan mendapat respon positif dari petani di desa mitra Kata Kunci : Padi beras merah; pengendalian hama terpadu; pascapanen padi. ABSTRACT Soporaru Hamlet is a hamlet in North Sumatra that has local specific rice, namely Natabo rice, which is super local rice owned by local farmers and has been officially marketed. However, until now the supporting of agricultural infrastructure is still inadequate, the habit of using chemicals to control plant pests and the insufficient number of agricultural machinery for rice processing. This activity aimed to make the farmers in partner village know the potential of natural resources in agriculture in their village, especially the brown rice, to apply the concept of integrated pest control and post-harvest rice technical guidance using a huller machine so that farmers can process their crops independently and efficiently, so that the quality and quantity of brown rice from partner villages has increased. In this activity, socialization and focus group discussions (FGD) were carried out with partner village farmers to discuss problems in the field so far, then the farmers were guided to control rice pests without chemicals, namely by using sweep net tools and technical guidance using a huller machine for the post-harvest stage of rice. This community service activity that was consisted of socialization, discussion and technical guidance was conducted well and received a positive response from the farmers in the partner village. Keywords: Brown rice; integrated pest control; post-harvest of rice.
