Peningkatan Kualitas Bibit Nyamplung (Calophyllum Inophyllum L) Dan Malapari (Pongamia Pinnata L) Dengan Aplikasi Mikoriza Dan Trichoderma Spp.

Nyamplung and Malapari a potential bioenergy crops on marginal land to be developed on the coastal land. The constraints of the coastal land is the less of water and soil nutrient. Input technology is needed in order to suceed the crop planting such as using bio fertilizer. Mycorrhizae plays an essential role in helping plants to absorb phosphate and increase the resistance to drought. Trichoderma spp involves in producing beneficial hormones for metabolism and helps break down organic matter. Utilization of biofertilizer is still rarely used as treatment in bioenergy plant seedlings. This study aimed to determine the quality of nyamplung and malapari seedlings after mycorrhizal and Trichoderma spp application in the nursery. Experiments were arranged in a complete randomized block design (RCBD). The treatment of media: soil as control (T), soil+organic fertilizer with ratio of 3:1(TK), soil+organic fertilizer+mycorhizae 10 g (TKM), soil+organic fertilizer+Trichoderma spp 10 g (TKT), soil+organic fertilizer+mycorrhizal 10 g+Trichoderma 10 g (TC). Application was done when the seedlings reached 1 (one) month old. Biofertilizer was sown around seedling roots. Each treatment consisted of 50 samples and 3 replications so the total seedlings were 750 seedlings. The results showed that after 6 and 12 months treatment malapari with organic fertilizer + mikoriza + Tricoderma spp (TC) gained 67.5% taller and 427% larger on dry weight of leaf than the control, whereas in nyamplung seedlings, TC treatment resulted better growth with diameter 8% larger, root length 78.56% longer, and total dry weight 7.88% heavier compared to control (T)

Variation of Dimension and Moisture Content of Agathis Labillardieri Werb. Fruit Based on Its Colour

Agathis labillardieri fruits can be distinguished according to their colours into three different colours i.e. light green and green. This study examined variation of dimension and moisture content of Agathis labillardieri based on those colours. The fruitys are measured their avarege fruits diameter, fruits length, fruit weight, moisture content and and germination percentage. The expweriment were laid out as a Completely Randomized Design. The result indicated that mature fruits have dark green colour. The charateristics of these green fruits are germination percentage 91 %, moisture content 31.2 %, fruit diameter 8.6 cm, length 8.7 cm and fruit weight 526.97 gr

The Potential of Vegetation Species Diversity for Ecotorourism Development at Nature Reserve of Panjalu Lake

The Nature Reserve of Panjalu Lake is one of the oldest conservation area in Indonesia. As a conservation area, Panjalu Lake has different species of flora that are useful as germplasm conservation, science and education. This study aims to know the potential of vegetation species diversity for ecotourism development at Nature Reserve of Panjalu Lake. The inventory method used is line plot sampling with intensity 15 % in two paths of 500 m (adjusted according length of the area) and 20 m width. Spacing between lines is 200 m and spacing between observation plot is 100 m. Within each path, 50 m x 20 m observation plots were established. The results showed that there are three species of seedlings with highest IVI, namely: Dysoxylum densiflorum Miq. (47.64 %), Calamus zollingerii (47.64 %), and Sterculia macrophylla Vent. (44.37 %). The four species at sapling stage with highest IVI are: Litsea cassiaefolia (114.29 %); Dysoxylum densiflorum Miq (57.14 %); Litsea sp. and Endiandra rubescens Miq (14.29 %). Three species at pole stage with highest IVI, namely: Dysoxylum densiflorum Miq. (143.04%); Litsea cassiaefolia (99.78 %) and Artocarpus elasticus Reinw 9.53 %). Three species at tree stage with highest IVI, namely: Dysoxylum densiflorum Miq (147.924 %), Litsea cassiaefolia (68.753 %), and Eugenia Fastigiata Miq ( 31.410 %).

Mutu Bibit Manglid (Manglieta Glauca BI) pada Tujuh Jenis Media Sapih

Tujuan penelitian ini adalah untuk mengetahui jenis media sapih yang mampu menghasilkan pertumbuhan dan mutu bibit Manglieta glauca BI terbaik. Penelitian dilakukan di persemaian Balai Penelitian Kehutanan Ciamis dari bulan Februari 2008 s/d September 2008. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 7 jenis media sapih yaitu M1 (Tanah + Pupuk kandang (3:1)), M2 (Tanah), M3 (Tanah + Pupuk kandang + Sekam padi (1:1:1)), M4 (Tanah + Pupuk kandang + Pasir (1:1:1)), M5(Tanah + Pupuk kandang + Serbuk sabut kelapa (1:1:1)), M6 ((Tanah + Pupuk kandang + Serbuk gergaji (1:1:1)) dan M7 ( Tanah + Pupuk kandang + Abu sekam padi (1:1:1)). Masing-masing perlakuan 60 bibit sehingga total bibit yang diperlukan adalah 7 x 60 = 420 bibit. Hasil penelitian menunjukkan bahwa campuran media M4 (Tanah+ Pupuk kandang+Pasir (1:1:1)) memberikan pertumbuhan diameter (0,469 cm), tinggi (22,678 cm) dan jumlah daun (9,978) M. glauca BI yang lebih baik dibanding media lainnya. Campuran media M5 (tanah+pupuk kandang+serbuk sabut kelapa (1:1:1)) memberikan berat kering akar (2,096), berat kering batang dan daun (4,046) dan indeks mutu bibit (0,132) M. glauca BI yang terbaik dibanding media lainnya. Kesimpulan dari penelitian ini adalah penggunaan campuran media M4 dan M5 masing-masing memberikan pertumbuhan dan indeks mutu bibit yang terbaik dalam teknik pembibitan M. glauca BI.
