The Effect of Method and Germination Paper Substrate on Viability of Eucalyptus Pellita F. Mull Seed

Improper seed handling of Eucalyptus pellita will reduce seed quality, so as to improve the viability of the seed proper handling techniques are needed. To investigate the seed germination potency as a result of seed handling germination seed tests are needed. The purpose of this study was to examine the effect of germination method and paper substrate on the viability of E. pellita seeds. Seeds used in this study were from seedling seed orchard in South Sumatra, South Kalimantan, and Riau. Seed germination methods used in the laboratory tests were method of top paper and between paper tests, besides that, different papers were used such as: paper substrate namely straw paper, towel paper, filter paper, and newspaper. Factorial experimental design completely randomized was used. The results showed that: (1) the method of germination and paper substrate was significant (2) the best paper substrate and germination method was the method of top paper test with used media of newspaper (germination percentage 204 seedling /0.01 grams).

Growth of Nyamplung (Calophyllum Inophyllum L.) on Three Planting Patterns and Dose of Fertilizer on Sandy Beach Pangandaran, West Java

Nyamplung (Calophyllum inophyllum L.) is one of the new alternatives of biofuels materials in the world. Hitherto, the information on the cultivation and processing techniques is very limited. This study aims to find out the growth of nyamplung on some cropping patterns on sandy beach Pangandaran in 4 (four) years. The experimental design used in this study was split plot design. The main plots were cropping pattern: agroforestry nyamplung, nyamplung monoculture and nyamplung + pandanus, and the subplot were fertilizer doses: (1) no fertilizer (control), (2) 5 kg of organic fertilizer + 100 gr/plant NPK and (3) 10 kg of organic fertilizer + 200 gr/plant of NPK fertilizer. Each combination treatment consists of 25 plants that were repeated 3 times , so that the total number of plants observed were 675 plants. The growth parameters observed: survival rate, height, diameters and number of branches of plant until 4 years. The results of this study showed that the interaction of treatments were statistically not significant. The growth of the plants was significantly affected by cropping pattern and fertilization. The Agroforestry pattern produces the highest survival rate and growth that is 97.33% with an average height of 220 cm and an average diameter of 5.08 cm. Recommended fertilizer doses are 5 kg of organic fertilizer for base and 100 grams of advanced fertilizer NPK twice a year.

Analisis of Stream Discharge of Micro Watershed and Its Utilization Potential

Trough understanding of hydrology characteristic of watershed, water resource can be managed for wider goals such as economic, social, and sustainainable utilization. In fact, current watershed managements have more been focused on erosion, sedimentation, drought, and flood control and less attention paid on fulfilling the need of upper watershed inhabitat on water yield. The research of Micro Watershed was conducted in three Micro Watersheds as representation of priority watersheds in South Sulawesi namely Mamasa, Saddang, and Jeneberang. The aim was to find out stream discharge pattern of those three Micro Watershed related to precipitation, landuse and its utilization potential for local community. The results showed that the more extensive forest cover, the better water yield and the higher its utilization potential . Concerning to precipitation and water yield, the three micro watersheds have the potentially to be source of water for irigation and household consumption.
