Keyword : Gulma, hutan rakyat, mulsa, pertumbuhan, tanaman potensial energi

Beberapa jenis tanaman potensial energi dapat dikembangkan di hutan rakyat sekitar Gunung Geulis, namun selama ini masyarakat belum menyadari potensi beberapa tanaman energi sehingga belum banyak di manfaatkan. Selain itu produktivitas hutan rakyat masih cenderung rendah, salah satu penyebabnya adalah teknik pemeliharaan yang kurang baik pada awal pertumbuhan. Gulma merupakan salah satu faktor pemicu menurunnya produktivitas kayu di hutan rakyat. Memberantas gulma selama ini memerlukan waktu dan biaya yang mahal sehingga diperlukan teknik pemberantasan gulma yang efektif yaitu pemulsaan. Produktivitas kayu dapat dilihat dari diameter batang, tinggi batang, jumlah daun, biomassa serta kondisi lingkungan dan keberadaan gulma. Maka dari itu penelitian ini bertujuan untuk mengetahui pemberian jenis mulsa terhadap pertumbuhan tanaman, kondisi lingkungan (suhu dan kelembaban tanah) serta keberadaan gulma. Penelitian ini dilaksanakan di lahan hutan rakyat Desa Jatiroke dengan melakukan penanaman bibit tanaman potensial energi. Metode penanaman dilakukan dengan Rancangan Acak Kelompok Faktorial dengan faktor pemberian 4 jenis mulsa (infarboard, kertas minyak, pelepah pisang dan tanpa mulsa) terhadap 5 jenis spesies (G. arborea, P. falcataria, C. arabica, A. cadamba dan A. mangium) yang dilakukan pengulangan 3 kali sehingga terdapat 60 satuan percobaan. Hasil penelitian tersebut dapat diketahui bahwa jenis tanaman potensial energi memiliki peningkatan diameter terbesar adalah G. arborea dengan pemberian mulsa kertas minyak (0,53 cm), sedangkan pertambahan tinggi batang paling besar terdapat pada P. falcataria dengan pemberian mulsa pelepah pisang (17,6 cm) dan petambahan jumlah daun paling banyak terdapat pada G. arborea dengan pemberian mulsa kertas minyak (34 helai) serta biomassa bibit paling besar terdapat pada A. cadamba dengan pemberian mulsa infraboard (32,04 gram). Berbagai jenis mulsa memiliki pengaruh terhadap kondisi lingkungan dimana suhu tanah paling rendah terdapat pada mulsa pelepah pisang (23,28OC) dan suhu tanah paling tinggi terdapat pada tanaman dengan pemberian mulsa infraboard (25,03OC). Kelembaban tanah paling besar terdapat pada tanaman dengan pemberian mulsa infraboard (85,43%) dan terendah terdapat pada tanaman tanpa mulsa (72,55%). Kerapatan gulma paling banyak terdapat pada tanaman tanpa mulsa (32,85%) dan kerapatan gulma paling sedikit terdapat pada tanaman dengan pemberian mulsa infraboard (23%).

Deskripsi Alternatif :

Several types of potential energy crops can be developed in the private forest around mount Geulis, but so far the community has not realized the potential of several energy crops so that they have not been widely utilized. In addition, the productivity of private forests still tends to be low, one of the causes is less maintenance techniques at the beginning of growth. Weed is one of the factors driving the decline in wood productivity in private forests. Eradicating weeds so far requires expensive time and cost so we need effective weed eradication techniques, namely mulch. Wood productivity can be seen from the stem diameter, stem height, number of leaves, biomass and environmental conditions and the presence of weeds. Therefore this study aims to determine the type of mulch to plant growth, environmental conditions (temperature and soil moisture) and the presence of weeds. This research was carried out on the private forest land of Jatiroke village by planting potential energy plant seeds. Planting method was carried out using Factorial Randomized Block Design with factors giving 4 types of mulch (infarboard, oil paper, banana midrib and without mulch) on 5 species (G. arborea, P. falcataria, C. arabica, A. cadamba and A. mangium ) which is repeated 3 times so there are 60 test units. The results of this study can be seen that the potential energy plant species have the largest increase in diameter is G. arborea by giving oil paper mulch (0.53 cm), while the highest increase in stem height was found in P. falcataria by banana midrib mulch (17.6 cm) and the highest number of leaves was found in G. arborea by applying oil paper mulch (34 strands) and the largest seed biomass was found in A. cadamba by infraboard mulch (32.04 grams). Various types of mulch have an influence on environmental conditions where the lowest soil temperature is found in banana midrib mulch (23.28oC) and the highest soil temperature is found in plants with infraboard mulch (25.03oC). The highest soil moisture was found in plants with mulch infraboard (85.43%) and the lowest was in plants without mulch (72.55%). The most weed density was found in plants without mulch (32.85%) and the least weed density was found in plants with infraboard mulch (23%).
