Abstract

ABSTRACT Dipterocarp species are the mainstay of forest products in the form of carpentry wood. Preserving the Dipterocarpaceae species of Dipterocarp Forest Plantation is important. This study aims to determine the percentage of optimal canopy cover for the growth of D. lanceolata. Furthermore, primary data were obtained by measuring and observing the growth of D. lanceolata in the form of diameter at breast height, tree height, the percentage of canopy, and environmental conditions (temperature and humidity). Meanwhile, secondary data, which was in the form of initial growth data when D. lanceolata, was newly planted and the general condition of the study site. The relationship between the percentage of canopy cover and growth in diameter and height of D. lanceolata aged 5 years growing in KHDTK Haurbentes has a significant effect but it has a low correlation. In addition, D. lanceolata can grow in the canopy cover percentage range of 40% - 65%.Keywords: Dryobalanops lanceolata, growth, canopy cover, diameter, heightABSTRAKJenis-jenis Dipterocarpaceae menjadi andalan dalam produk hasil hutan berupa kayu pertukangan.

Abstract

The climate is defined as the condition of mean of air temperature, precipitation, the air pressure, the direction of the wind, air moisture and other parameters in long time. The fluctuations of high rainfall significantly affect plant productivity, such as farming, forestry and agriculture. The amount of rainfall is very important in determine the result of the cultivation of plants. Especially if it is associated with the influence of the increase of temperature. The result of this research showed that the type of land at research location were incepticol (land suitability 1) and ultisol (land suitability II, III, IV and V). The mean of annual rainfall in research location (since 2012 until 2014), were 1500 until 2000 mm/years. The mean air temperature was 26-27 oC and air moisture between 82-85.9 %. Keywords: Melapi Timber, rainfall, temperature, type of land, variability

Abstract

Shorea leprosula is one of the tree species within Dipterocarpaceae family which is a major source for timber production. The species has been planted massively in Gunung Dahu Research Forest (GDRF) in Leuwiliang- Bogor. Gunung Dahu Research Forest is a man-made dipterocarp forest which has varying slope class, topoghraphy and canopy cover. Furthermore, Natural regeneration is an important ecological factor in assessing the ability of forest regeneration, including in a plantation forest. Therefore, it is necessary to know the effect of slope and canopy cover on the regeneration of S. leprosula in order to characterize what factors support and constraint the naturally regenerating forest of Gunung Dahu Research Forest. Regeneration capacity of the species was observed in purposive plots which have been recorded for their flowering events. Seedlings were grouped into seedlings, and saplings. It was measured by census method in every slopes. Meanwhile, Variable observed included, number of available seedling at each slope category slope with its canopy cover, height and diameter of seedlings, and litter thickness. Regeneration capacity of the species was observed in purposive plots which had been recorded for their flowering events. Seedlings and saplings were taken using the census method. The results show that flat slope with shady canopy cover has the highest capacity of seedlings and the best growth. The uneven distribution of height and diameter indicates the need for silviculture action; such as, maintenance.

Abstract

Mindi (Melia azedarach L.) is mostly found in community forests of West Java. One of the important factors affecting productivity of community forests is the use of quality seed. Due to scarcity of seed sources, however, seed quality is not easily available. Currently, community forests serve also as ad hoc seed sources that are usually without appropriate quality assessment. This research was aimed to determine baseline information on spatial variability of mindi fruits collected from five seed sources, and seedling growths treated in seven different growing media consisting mixtures of soil, rice husk, sand and cattle manure. Five mindi populations were selected in the following villages: Nagrak (Bogor), Babakan Rema (Kuningan), Padasari (Sumedang), Sukakarya (Bogor) and Gambung (Bandung). The results showed that variability of seed dimension (CV=4.82-14.37%) and seedling growth (11.79-21.77%) were moderate. The mindi fruits from Nagrak were found to be the biggest in terms of size (1.22 ± 0.17 cm), weight (0.40 ± 0.04 g), and seed set (85.47 ± 15.09%). In addition, the seedling growth from Nagrak was also better than those of other villages showing its potential for future seed sources. Growing media containing cattle manure were observed consistently to be the best for seedling growth. The findings are useful in supporting scientifically the selection of seed sources from community forests.

Abstract

Seedling quality contributes significantly to the development of industrial forest plantations. This study assessed Dicranopteris linearis (Resam) and rice husk charcoal mixtures as an alternative nursery media for Acacia mangium Willd. seedlings. The study was carried out using a Completely Randomized Design, and the data were analyzed using ANOVA. Five mixtures of resam and rice husk charcoal were tested: A (100% control), B (80%:20%), C (70%:30%), D (60%:40%), and E (50%:50%). The ratio of 70%:30% yielded the best performance, with a mean height of 12.84 cm, fresh weight of 4.63 grams, dry shoot weight of 1.53 grams, and a Seedling Quality Index (SQI) of 0.0018. These findings highlight mixed media C as the most effective composition and confirm the potential of resam and rice husk charcoal mixture as an effective and sustainable nursery media for industrial forest plantation.

Abstract

Luasan hutan di Indonesia yang semakin berkurang akibat deforestasi memerlukan pengelolaan hutan lestari. Shorea stenoptera Burck merupakan salah satu jenis endemik tanaman kehutanan di Borneo. IUCN menyatakan bahwa jenis tersebut termasuk ke dalam status hampir terancam (Near Threatened). Tujuan penelitian ini adalah menganalisis komposisi jenis, struktur tegakan, dan regenerasi alami tegakan S. stenoptera, serta mengidentifikasi pengaruh aspek biofisik terhadap keragaan regenerasi alami S. stenoptera di KHDTK Haurbentes, Kabupaten Bogor, Jawa Barat. Metode yang digunakan adalah analisis vegetasi dengan membangun petak pengamatan sebanyak 5 petak. Hasil penelitian menunjukkan bahwa jenis S. stenoptera mendominasi pada setiap tingkat pertumbuhan pada petak pengamatan S. stenoptera. Struktur tegakan menunjukkan kurva J terbalik. Hal tersebut mengindikasikan tegakan S. stenoptera mengalami perubahan formasi ke hutan alam. Regenerasi S. stenoptera menunjukkan regenerasi normal dengan kerapatan individu semakin berkurang seiring bertambahnya kelas diameter. Aspek biofisik seperti kelerengan dan elevasi sangat memengaruhi pertumbuhan S. stenoptera.

Abstract

Zona tradisional Taman Nasional Gunung Halimun Salak (TNGHS) merupakan zona yang sangat dimanfaatkan oleh masyarakat setempat untuk memenuhi kebutuhan sehari-hari dengan memanfaatkan sumber daya hutan bukan kayu dan menerapkan sistem agroforestri dengan komoditas utama poh-pohan (Pilea melastomoides). Pemantauan hutan di zona tradisional TNGHS sangat penting dilakukan sebagai bagian dari pengelolaan hutan lestari dan realisasi dukungan program Forestry And Other Land Use (FOLU) Net Sink Indonesia 2030. Penelitian ini bertujuan menganalisis kerapatan vegetasi berdasarkan nilai NDVI; menganalisis tingkat keanekaragaman jenis tumbuhan dan struktur tegakan di zona tradisional TNGHS. Selanjutnya dilakukan pendataan keanekaragaman jenis tumbuhan di kawasan tersebut berdasarkan nilai NDVI kerapatan vegetasi. Nilai NDVI diperoleh menjadi tiga kelas yang memiliki kondisi lahan yang berbeda. Nilai kelas 1 berkisar antara 0,147 sampai 0,273 memiliki kerapatan vegetasi yang rendah. Kelas 2 dari 0,273 sampai 0,319 memiliki kerapatan vegetasi sedang. Sedangkan kelas 3 memiliki kerapatan vegetasi tinggi dengan nilai 0,319 hingga 0,433. Keanekaragaman jenis tumbuhan memiliki 60 jenis yang berbeda dari total tiga kelas. Kerapatan semai lebih rendah dari pancang, namun pada tingkat tiang dan pohon semakin menurun yang menandakan struktur tegakan seimbang. Tingkat semai yang rendah disebabkan oleh terhalangnya pertumbuhan semai akibat pembersihan yang dilakukan oleh masyarakat setempat untuk persiapan penanaman tumbuhan bawah karena masyarakat lebih memilih menanam tumbuhan bawah yang lebih cepat panen dibandingkan semai tumbuhan berkayu.
