Pengaruh Pemeliharaan Terhadap Pertumbuhan Tanaman Dan Permudaan Alam Dalam Uji Efektivitas Silvikultur Tebang Rumpang

Abstract

ABSTRAKTebang rumpang merupakan salah satu sistem silvikultur alternatif yang berlandaskan pemudaan alam dengan unit perlakuan tegakan terkecil berupa rumpang-rumpang yang tersusun dalam unit jalan sarad. Sistem tersebut belum teruji secara menyeluruh, termasuk dalam hal pemeliharaan tegakan muda di dalam rumpang. Penelitian dilakukan di KHDTK Kintap, Kalimantan Selatan, dengan tujuan mengetahui pengaruh interaksi pemeliharaan antara lebar pembebasan pohon dengan lama waktu pembebasan terhadap pertumbuhan tanaman Shorea leprosula, anakan alam S. parvistipulata, dan Croton graffithii di dalam rumpang. Hasil penelitian menunjukkan bahwa pengaruh interaksi pemeliharaan antara lebar pembebasan dengan waktu pembebasan terhadap pertumbuhan tanaman dan permudaan alam di dalam rumpang secara statistik tidak nyata. Demikian juga pengaruh tunggal dari lebar pembebasan dan frekuensi pembebasan terhadap pertumbuhan tinggi, diameter batang dan tutupan tajuk, secara statistik tidak nyata. Dapat disimpulkan bahwa pemeliharaan khususnya pembebasan tanaman dari gulma tidak mempengaruhi pertumbuhan permudaan. Pertumbuhan tersebut mungkin lebih dipengaruhi oleh kesuburan tanah, intensitas cahaya, temperatur, dan kelembaban di dalam lingkungan rumpang. Kegiatan pemeliharaan 24 bulan setelah rumpang dibuat tidak disarankan.Kata kunci : sistem silvikultur, rumpang, pemeliharaan, tanaman, anakan alam ABSTRACT Gap cutting is one of alternative silvicultural systems that applied based on natural regeneration, which uses gaps formatted in skid trails as smallest treatment unit in tree stands. This system has not been comprehensively studied, including the effects of silvicultural treatments in young stands. This study was conducted in KHDTK Kintap South Kalimantan, aiming at knowing the effects of interaction between the width of gap and duration of treatment on the growth of planted S. leprosula and natural seedlings of S. parvistipulata, as well as Croton graffithii that grow within the gaps. The results showed that the interaction between the width of gap and duration of treatment on plant growth and natural regeneration is not statistically significant. Likewise, the effect of gap width and gap frequency on height and diameter growth, and the width of canopy cover is not statistically significant. In conclusion, silvicultural treatments, especially weeds exemption does not affect the growth of seedlings. The growth may be more influenced by soil fertility, light intensity, temperature, and humidity in the gaps. Silvicultural treatments 24 months after creating gaps are not recommended.

Diameter growth performance and estimated carbon stock of Shorea spp. at KHDTK Haurbentes, Bogor

“…The results of the research which had conducted by Hardjana and Suastati (2014) stated that silvicultural treatment in a stand could optimize plant growth in the stand. Furthermore, research which had conducted by Panjaitan (2016) stated that apart from maintenance, there are other factors which have a greater influence on the diameter growth of Shorea spp. compared to maintenance; such as light intensity, humidity, soil fertility, and suitability of plant species with environmental conditions.…”

Growth Evaluation of Red Meranti Species in Restoration Area of Gunung Dahu Research Forest, Bogor

“…The competitions between plants were very high those making the number of small-diameter plants were available in numerous sizes (Nambiar & Sands, 2011;Caine & Dybzinski, 2013;Looney, D'Amato, Fraver, Palik, & Reinikainen, 2016). Considering the condition, support on tree growth can be achieved by practicing silvicultural treatment is a need to perform (e.i horizontal/vertical roguing) to ensure more growing spaces and maximize the light intensity (Pamoengkas & Prasetia, 2014;Siswadi, Umroni, Pamungkas, & Manurung, 2015;Panjaitan, 2016).…”

The effect of air quality due to household waste sewers on the growth of cayenne pepper (Capsicum frustescens L.)

“…Plant maintenance is carried out mainly by land maintenance. Land maintenance can be done either by maintaining soil quality by fertilizing or by structuring the vegetation that grows on it [4][5]. Plant maintenance that is no less important is plant protection.…”
