The study was conducted in the HCV areas of three oil palm plantation companies and secondary forest in Riau Province. Data was collected by analyzing vegetation measuring 1.28-2.56 ha/plot in the HCV area and 3.84 ha/plot in secondary forest. Data analysis was carried out using relative density, and analysis of regeneration conditions were included in five categories (good, poor, fair, none, new). Data analysis related to the assessment of the prospect of HCV areas is carried out from the results of the analysis of the effectiveness of the HCV area and plant sustainability. The HCV area prospect assessment is grouped into three categories, namely prospective, moderately prospective, and not yet prospective. The results showed that the HCV area was not yet effective and the condition of important plant species was not sustainable. The HCV area has not been effectively assessed from the comparison of the value of the vegetation community between the HCV area and secondary forest, including low (<25%). PT A's HCV area in the form of forest has a higher effectiveness value than other HCV areas and secondary forest. The results showed that the most important plant species regeneration conditions were included in the none category (57.14%). This category shows that plant species are not yet sustainable because they are only found at one growth level, namely trees. The purpose of the existence of HCV areas is to maintaining and conserving plant diversity in oil palm plantations has not been implemented properly.

Penelitian dilakukan di areal NKT tiga perusahaan perkebunan kelapa sawit dan hutan sekunder di Provinsi Riau. Pengumpulan data dilakukan dengan analisis vegetasi berukuran 1,8-2,6 ha/plot di areal NKT dan 3,84 ha/plot di hutan sekunder. Analisis data dilakukan dengan menggunakan kerapatan relatif, dan analisis kondisi regenerasi yang dimasukkan dalam lima kategori (good, poor, fair, none, new). Analisis data terkait penilaian prospek areal NKT dilakukan dari hasil analisis efektivitas areal NKT dan kelestarian tumbuhan. Penilaian prospek areal NKT dikelompokkan menjadi tiga kategori yaitu prospektif, cukup prospektif, dan belum prospektif. Hasil penelitian menunjukkan bahwa areal NKT belum efektif dan kondisi spesies tumbuhan penting yang belum lestari. Areal NKT belum efektif dinilai dari perbandingan nilai komunitas vegetasi antara areal NKT dengan hutan sekunder termasuk rendah (<25%). Areal NKT PT A yang berbentuk hutan memiliki nilai efektivitas lebih tinggi dibandingkan dengan areal NKT lainnya dan hutan sekunder. Hasil penelitian menunjukkan bahwa kondisi regenerasi spesies tumbuhan penting paling banyak termasuk kedalam kategori none (57,14%). Kategori ini menunjukkan spesies tumbuhan belum lestari dikarenakan hanya ditemukan pada satu tingkat pertumbuhan yaitu pohon. Tujuan keberadaan areal NKT adalah menjaga dan melestarikan keanekaragaman tumbuhan yang ada di perkebunan kelapa sawit belum terlaksana dengan baik. Kata kunci: Nilai konservasi tinggi, kelestarian, konservasi, tumbuhan, perkebunan sawit PENDAHULUAN Perkembangan perkebunan kelapa sawit memberikan dampak positif dan dampak negatif. Salah satu dampak negatif yang ditimbulkan ialah menurunnya keanekaragaman hayati (Azhar dkk., 2014). Adanya konversi dari hutan alam menjadi perkebunan kelapa sawit menyebabkan hilangnya keanekaragaman hayati khususnya spesies tumbuhan (Obidzinski dkk., 2012; Colchester dkk., 2011). Petrenko dkk (2016) menyatakan bahwa pada tahun 2000 hingga 2012, Indonesia
