Penelitian dilaksanakan pada hutan tanaman mahoni (Swietenia macrophylla King.) umur 2, 5 dan 9 tahun yang berlokasi di Resort Polisi Hutan (RPH) Getas, Bagian Kesatuan Pemangkuan Hutan (BKPH) Monggot, Kesatuan Pemangkuan Hutan (KPH) Gundih, Jawa Tengah. Penelitian ini dilakukan untuk mengetahui kondisi komunitas vegetasi tegakan mahoni pada beberapa fase umur dan potensinya dalam pengendalian limpasan dan erosi. Masing-masing umur tanaman dibangun 2 petak ukur pengamatan limpasan dan erosi dengan ukuran 22,1 m x 4 m per petak ukur. Sebagai kontrol dibangun 2 petak ukur dengan ukuran yang sama pada lahan terbuka (tanpa tanaman). Pengamatan vegetasi juga dilakukan di dalam petak ukur pengamatan erosi. Hasil penelitian menunjukkan bahwa pengendalian erosi dan limpasan permukaan tegakan mahoni lebih banyak dikendalikan oleh keberadaan seresah dan tumbuhan bawah. Tingkat erosi yang terjadi pada tegakan mahoni umur 2, 5 dan 9 tahun menurun, yaitu masing-masing menjadi 49,4, 15,3 dan 8,7 % dibandingkan dengan control (lahan tanpa tanaman). Besar limpasan air permukaan pada tegakan mahoni umur 2, 5 dan 9 tahun yang dicerminkan oleh nilai koefisien erosi masing-masing sebesar 0,24 (4 % terhadap kontrol), 0,19 (24 % terhadap kontrol) dan 0,14 (44 % terhadap kontrol). Kegiatan seleksi pada kegiatan pemuliaan akan menghasilkan benih unggul yang akan meningkatkan produksi kayu (biomasa) dan menurunkan laju limpasan dan erosi.

A study on the effect of organic fertilizer dosage on growth of mahoni (Swietenia macrophylla King) was conducted in the rehabilitation area of Samboja Lestari, East Kalimatan. The purpose of this research is to determine the optimal dosage of organic fertilizer applied for mahoni planted in degraded land areas invaded by alang-alang (Imperata cylindrica Beauv.). Four organic fertilizer dosagse (1 kg, 2 kg, 3 kg, 4 kg per) p tree were testeted. Randomized Complete Block Design with five replications was used for this study. Every dosage treatment was applied on 5 plants with the spacing of 5 m x 5 m. The total plants observed were125 mohoni plants. The results showed that dosage treatment of organic fertilizer did not give significant effect on the survival percentage and height growth of mahoni. But dosages higher than one kg organic fertilizer resulted in died plant as much as 35 % compare with that of control. The treatment of 2 kg organic fertilizer gave optimal to height growth.
Mahogany is a type of Multiple Purpose Tree Species (MPTS), which has the highest abundance at the seedling stage with INP value 42.6% from 11 species that have found in the PT Cibaliung Sumberdaya forest. Natural regeneration of mahogany very potential to be developed. Problems in the develovment of natural seedlings of mahogany is growth inhibition caused by use improper planting medium and organic fertilizers that incompatable. The purpose of the study is to assess the response of natural seedling mahogany (Swietenia macrophylla King) growth in soil and compost media. The study used three intervals plant height (10-20 cm, 21-30 cm, 31-40 cm), three planting medium (1:1 (v/v), 1:3 (v/v), 1:0 (v/v)), and three long soaking time (0 hour, 6 hours, 12 hours). The results showed that treatment of T3M1 and T3M2 produced leaflets growth highest with average value 8 leaves/plant. Treatment T1M2, T1M3 and T2M3 produced leaflets growth lowest with average value 3 leaves/plant. Key words: natural regeneration, mahogany, MPTS

Mahogany is a potential species commonly cultivated in West Java. The community usually plants this species in a cropping system with combinations of agricultural crops. Topography, climate, and intensive soil preparation affect on vulnerability of land productivity due to severe runoff and erosion impact on growth and crop production. This condition can be controlled by applying soil conservation techniques such as vertical mulch to reduce runoff and erosion as well as to maintain soil fertility. Eficiency of vertical mulch channel distance is needed to reduce the application cost. This research aims to determine the effect of different distances of vertical mulch channels on mahogany growth and maize production as wel as its effectiveness in controlling runoff , erosion, and nutrient loss. The research was conducted at Carita Forest Research in year 2005-2008 using a randomized block design. Treatment applied was vertical mulch with six and 12 m intervals on the plots of mahogany (Swietenia macrophylla King) and maize (Zea mays L.) cropping system. Observations include height and diameter growth of mahogany, runoff and erosion, and cost required for one hectare area. The result showed that six meter intervals of vertical mulch increased the height and diameter growth of mahogany by 25% and 66% respectively compared to the control. That treatment also reduced runoff and erosion by half, and nutrient loss due to runoff and erosion were reduced up to three and five times respectively. Application of the six meter interval on the mahogany cropping system produced 581 kg/ha/year maize or 47% higher instead of control, and in a hectare the cropping system will require Rp 3,250,000 or more expensive Rp 250,000 compared to control.
