Abstract

ABSTRACTThe growth of oil palm plantation area for Crude Palm Oil (CPO) has been increasing. In Indonesia, oil palm plantation is more than 5 million ha with 14 million of CPO production. However, there are still unutilized wastes like Empty Fruit Bunch (EFB) which can be processed for some other products. EFB can be processed for pulp, craft, plastics and particle board. With Clorin Bleaching Free Technology, EFB can be  processed for paper with 75 - 80% brightness. Wastes of EFB is related to plantation age. Average of EFB biomass is 10.27 ton ha-1 and can give income for about USD 28 per ha. The enhancement of economic value can control forested area conversion to palm oil plantation.ABSTRAKPertumbuhan perkebunan kelapa sawit untuk produksi minyak semakin meningkat. Lebih dari 5 juta hektar kebun kelapa sawit yang ada di Indonesia dengan produksi minyak sawit mencapai 14 juta ton. Potensi kebun tersebut menyimpan limbah tandan buah kosong (EFB) yang sangat tinggi yang dapat dimanfaatkan sebagai bahan alternatif menghasilkan pulp, kerajinan, plastik dan dengan teknologi Chlorin Bleaching Free pada EFB dapat dihasilkan kertas dengan tingkat keputihan mencapai 75 - 80%. Limbah EFB memiliki kaitan yang erat dengan umur. Biomassa EFB mencapai 10,27 ton/ha dan bila dimanfaatkan untuk produksi pulp dapat menghasilkan 28 USD/Ha. Pening- katan nilai ekonomi dapat mengendalikan konversi lahan berhutan untuk pembangunan perkebunan kelapa sawit.

Abstract

Activities of  forest management  require a well planned, systematic and well directed handling, so that  achieving  maximal  and  beneficial  results in terms  of  economic,  ecological  and  social prospects.   In relevant  to data on trunk  volume of  available tree stands  are required  to set up a plan  intended  to produce  sustainable   timber. The  research was conducted  in the Darmaga  and Haurbentes  research forests of  the Forest  and Nature  Conservation  Research and Development Center located in West Java. The  trunk  volume model as conceived  was based  on the Smalians formula employed to particular tree species (i.e.  Shorea balanggeran;  S. guisso;S.leprosula; S.  mecistopteryx; S.ovalis; S. palembanica;S. pinanga;S.  selanica;S.seminisand S.  stenoptera).This  model could estimate the trunk  volume with non-destructive    sampling.  In this way, therefore,  the trunk  volume  can be estimated  from the tree diameter  on a single variable.

Abstract

Pembangunan hutan tanaman jabon merah (Anthocephalus macrophyllus (Roxb.) Havil) memerlukan bibit yang bermutu. Bibit berkualitas dapat dihasilkan dengan mengoptimalkan proses fisiologis tanaman seperti fotosintesa dan metabolisme yang dipengaruhi oleh faktor luar seperti sinar matahari, air, hara mineral dan kondisi tempat tumbuh. Penambahan inokulan mikoriza dan pupuk sebagai penyedia hara dapat memacu pertumbuhan dan meningkatkan daya hidup bibit. Tujuan penelitian ini adalah mempelajari pengaruh penggunaan mikoriza dan pupuk NPK terhadap pertumbuhan bibit jabon merah. Penambahan mikoriza 5 gram dan NPK 0,5 - 1,0 gram/polybag media tanah solum B dapat menghasilkan bibit jabon merah dengan tinggi 28,33 – 30,33 cm dan diameter 5,42 – 6,70 mm pada umur 5 bulan.

Abstract

The desirability to explore other tree species that can be used to substitute Acacia crassicarpa in forest plantation has increased. One of the early insights that must be known is the growth performances of tree species candidates, especially in planting conditions (site and silviculture) similar to A. crassicarpa plantation. This study evaluated the growth performance of jabon (A. cadamba Miq.) and its relationship with soil properties in a drained peatland. The research was conducted by establishing experimental plots of jabon in a drained peatland (DP) using a randomised complete block design with three spacing (2m x 3m, 2.5m x 3m, 3m x 3m) as treatment and three blocks as replications. The study observed survival, growth and soil chemical properties. At 24 months after planting (MaP), since the toxicity of soil micronutrients was excessive as one of the main factors; the mortality rate of jabon was high (62%), while its growth was poor (height = 259 cm and DBH = 3.74 cm) in drained peatland. However, the study observed that 7% of jabon had good growth, with a range of height growth at 24 MaP of 401–660 cm. These results indicated that though overall jabon did not show good growth in DP, however, it was found that 7% of jabon had promising growth; therefore, it was suggested that through tree improvement program and certain treatments to overcome micronutrient toxicity and weed suppression, the possibility of jabon was able to be developed in a DP for forest plantation is still.
