Abstract

ABSTRAK Penanaman pengayaan intensif pada kawasan hutan bekas tebangan (Logged Over Area, LOA), telah dilakukan oleh PT Sari Bumi Kusuma sejak tahun 1999. Luas kawasan yang telah ditanami dengan jenis-jenis indigenous grup meranti sekitar 21.000 ha sampai dengan tahun 2007. Jenis meranti yang digunakan untuk penanaman adalah Shorea leprosula Miq, S. parvifolia Dyer, S. platyclados Sloot. ex Foxw, S. johorensis Foxw dan S. dasiphylla Foxw. Tujuan dari penelitian ini adalah untuk mendapatkan informasi hasil evalusi pertumbuhan jenis-jenis Dipterocarpa terpilih dan pengaruh naungan terhadap pertumbuhan yang ditanam dengan sistem Tebang Pilih Tanam Jalur dengan penerapan teknik silvikultur intensif (TPTJ-SILIN). Penelitian mengunakan tanaman meranti pada sistem TPTJ yang telah berumur 1-5 tahun. Pada setiap kelas umur tanaman dibuat 10 buah plot PUP monitoring dengan ukuran 50 m x 100 m (0,5 ha). Dari penanaman lima tahun terakhir riap DBH tanaman tertinggi adalah S.leprosula Miq, yaitu 1,94 cm/thn dan diikuti oleh S.platyclados Sloot. ex Foxw, S.johorensi Foxw, S.parvifolia Dyer dan S.dasiphylla Foxw yang masing-masing mempunyai riap DBH sebesar 1,81, 1,59, 1,58 dan 1,49 cm/thn. Pertumbuhan yang masih sangat bervariasi di lapangan disebabkan karena perbedaan tingkat naungan. Perbaikan tipe naungan 1-2 dan 1-3 akan meningkatkan perkembangan DBH antara 17-69% dan 20-96%.  Sedangkan pada variabel tinggi perbaikan tipe naungan 1-2 dan  tipe naungan 1-3, masing-masing akan meningkatkan pertumbuhan tinggi antara 18-22% dan 18-33%.

Abstract

Kerusakan hutan tropika basah dapat menimbulkan dampak lingkungan berupa penurunan keanekaragaman hayati dan terganggunya fungsi serta stabilitas ekosistem. Tujuan dari penelitian ini adalah untuk mendapatkan bukti apakah perubahan hutan tropika basah menjadi bentuk penggunaan lahan lain berakibat pada penurunan keragaman dan kelimpahan semut, dan untuk menunjukkan apakah semut dapat dijadikan sebagai bio-indikator perubahan sistem penggunaan lahan (SPL). Penelitian ini dilakukan di Jambi Sumatra pada akhir musim penghujan (Mei−Juni) 2004 pada berbagai taraf intensifikasi SPL. Inventarisasi dan koleksi semut dilakukan dengan menggunakan metode “Winkler” pada enam SPL, yaitu: hutan primer, hutan sekunder, perkebunan karet, perkebunan kelapa sawit, ladang ketela pohon, dan padang alang-alang. Hasil penelitian menunjukkan bahwa ditemukan 50 genus semut pada 6 SPL tersebut. SPL tidak berpengaruh secara nyata terhadap keragaman dan kelimpahan seluruh semut tetapi berpengaruh secara nyata terhadap kelompok semut pesaba dan semut predator. Keragaman jenis dan kelimpahan yang tinggi dari semut predator ditemukan pada SPL hutan primer dan hutan sekunder. Keragaman jenis dan kelimpahan menjadi rendah apabila SPL hutan diubah menjadi SPL ladang ketela pohon. Kelimpahan semut pesaba tertinggi diketemukan pada SPL perkebunan kelapa sawit. Data yang diperoleh menunjukkan bahwa semut dapat digunakan sebagai bio-indikator dalam perubahan SPL di kawasan Jambi, Sumatra.

Abstract

Perum Perhutani has an important role in providing food and wood for people. Diversity and diversification of food will reduce the need for one type of food, namely rice as a staple food. Some tuber and rhizome are source of alternative foodstuffs, such as taro and arrowroot. This study aimed to determine the suitability and productivity of arrowroot and taro planted under old superior teak clones with several levels of stand density. Arrowroot and taro were planted under 14-year-old teak stands with 4 levels of density. Both plants were planted in the form of an array, measuring of 3m x 15m, with a spacing of 75cm x 75cm between plants. They were arranged in Randomized Completely with Block Design (RCBD) placed in 4 blocks of observation as replications.  The results showed that under superior teak clone had the potential to be planted with arrowroot and taro. Teak stand density influenced significantly some characteristics of arrowroot (leaves number, leaves area, stem height, stem diameter, root length) and taro (stem diameter, tuber diameter). Arrowroot productivity per hectare increased with low density of teak stands, accounted for 55, 59, 80, and 88 kg respectively. Meanwhile, taro productivity from very high to low teak density were 365, 301, 523, and 426 kg/ha. The novelty of this study is that there is no record of intercropping studies on old superior teak clones, so this is among the first studies. The benefit of from this research result, it could be employed by Perhutani to support the Indonesian government in the national food security program

Abstract

Arrowroot (Maranta arundinacea L.) is a multipurpose plant that can grow under the stands so that the species has the potential to develop in the pattern of agroforestry. Initial information of arrowroot plant population as a source of germplasm for plant material/superior varieties and their agroecological characteristics in the field is indispensable. The study aims to determine the distribution, agroecological characteristics and potency of arrowroot in Garut regency. The methods include: (1) the study of literature and direct communication with stakeholders and the public, (2) field survey to collect data on distribution, cultivation status, abundance and productivity of arrowroot plant using a single plot, and (3) data collection of arrowroot agroecological characteristics include: vegetation analysis and geoklimat factors. The research results indicate that the arrowroot populations distribute in groups with a fairly broad ecological range i.e. altitude 6-1351 masl, temperature 20-36o C, relative humidity RH 40-72%, light intensity 12-56% dan pH 4.16-7,40 (acid to neutral) and in the low to high soil fertility condition. Falcataria moluccana as the major private forest species dominates in all zones of altitude, especially on the stage of the tree. Arrowroot abundance by elevation zones is 63,750 plants/ha (lowlands), 43,864 plants/ha (plains) and 73.333 plants/ha (plateau). The potential production for all elevations ranged from 15.40 to 163.2 g/plants. Cikajang and Cilawu populations have good potential to produce the high yield of tuber for arrowroot cultivation in Garut District.

Abstract

Agroforestry, the practice of growing trees and crops in interacting combinations, has a pivotal role to reduce the CO2 concentration in the atmosphere, and it subsequently sequesters the carbon in part of stems, branches, roots, and crowns of the trees composing their vegetation communities. The objective of the research is to know the carbon sequestration in the three agroforestry practices; those are multilayer tree garden, taungya, and home garden. The research was carried out from April 2017 to March 2018 at Sragen and Karanganyar regency central Java Province. Plot method, with the plot size of 20m x20m for trees, 10m x10 m for pole, and 5m x5m for sapling, was used in the sampling. The carbon sequestration was measured by Chave's allometric equation. The carbon sequestration of above ground the trees planted at taungya was 265.18 kg C ha-1 y-1, in home garden was 236.29 kg C ha-1 y-1, and in multi layer tree garden was 290.14 kg C ha-1 y-1. Seasonal fluctuation of the higest carbon sequestration in home garden occurs on October-December; in multilayer tree garden occurs on January-March; and in taungya occurs on July-September. Key words: Agroforestry practices, G.versteegii, seasonal fluctuation, Carbon sequestration

Abstract

The decomposition and its nutrient release were the key ecological process that had a broad role in the forest ecosystem. This study aimed to investigate the leaf litter decomposition rate and its nutrient release of three native tree species of tropical peat swamp forest, namely Macaranga pruinosa, Macaranga gigantea, and Cratoxylum arborescens and one exotic species i.e Acacia crassicarpa. The decomposition and nutrient release were monitored in an experimental plot using litter bag technique. The initial litter quality of each litter and micro-environment properties were also observed. The result showed that the decomposition and its nutrient release were insignificantly different among native tree species and also between native species and Acacia crasssicarpa. The litter decomposition of all tree species was slow; with the range of k was 0.98-1.19 year-1. However, the P and K release from the decomposition of native species litter after four months of incubation were quickly, ranging 70-74% and 88-93%. We were suggested that the high of lignin content in the leaf litter (36-39%) was the main factor that made slow decomposition. These findings could be used as one of the tools in tree species selection for peat swamp forest rehabilitation.

Abstract

Although Gyrinops versteegii has been domesticated by local community in Sragen Regency, the environmental factors and species which have high compatibility with G. versteegii still have not known yet. The objectives of this research were 1) to know which one of those vegetation communities that gives the best the diameter and height growth of the domesticated G. versteegii, and 2) to know the environmental factors that influenced the growth of the diameter and height of the domesticated G. versteegii. Sampling was done systematically with a plot of size 20 × 20m for trees, 10 × 10m for poles, and 5 × 5m for saplings with a total of 28 plots. SPSS Program version 22 was used for cluster, one-way anova, correlation, and multiple regression analysis. The results showed that for achieving the best G. versteegii growth, the G. versteegii should be planted under the community group which was dominated by Paraserianthes falcataria, Tectona grandis, Gliricidia sepium, and Eugenia aquea. Environmental factors affecting diameter growth of G. verteegii were organic carbon of the soil and the vegetation density. Meanwhile the environmental factors affecting the height growth of G. versteegii were temperature, light intensity, relative light intensity, organic carbon, C N ratio, P, Mg, air humidity, and clay content.
