Abstract

Aren plantations in Sungai Raya Sub-District are among the largest in Hulu Sungai Selatan Regency, which is 40.57 ha. The growth of Aren is a problem that is considered necessary to be done. This study aims to identify the damage in Aren saplings and calculate the percentage of Aren saplings' health. The research location was carried out in Sungai Raya sub-district, Batang Kulur Kanan village. Collecting data by purposive sampling, making seedling-level plots with a distance of 10 meters between plots, documenting the health condition of plants in each research plot, identifying pests found in Aren and taking field condition data including: pH, air temperature and humidity. The data is then processed based on the Environmental monitoring and assessment program (EMAP) classification book. Based on the results of the study, it was obtained from 118 saplings 33.89% (disease), 37.28% (broken leaf part of the sapling), 35.59% (damaged leaf), 16.10% (severity level 20-29%). Percentage of health 56 seeds (47%) sick and 62 seeds (52.54%) healthy.

Pertumbuhan tingkat anakan aren merupakan permasalahan yang dianggap perlu untuk dilakukan. Tujuan penelitian ini untuk mengidentifikasi kerusakan yang terdapat pada anakan aren dan menghitung persentase kesehatan anakan aren.

Pengambilan data secara purposive sampling, jarak petak tingkat semai 10 meter, mendokumentasikan kondisi kesehatan tanaman tiap petak penelitian, mengidentifikasi hama yang terdapat pada anakan aren dan pengambilan data kondisi lapangan meliputi pH, suhu udara dan kelembaban udara. Data kemudian diolah berdasarkan buku klasifikasi Enviromental monitoring and assessment program (EMAP). Berdasarkan hasil penelitian diperoleh dari 118 anakan 33,89% (penyakit), 37,28% (bagian bibit yang rusak daun), 35,59% (daun rusak), 16,10% (tingkat keparahan 20 – 29%). Persentase kesehatan  56 anakan (47%) sakit dan 62 anakan (52,54%) sehat
