The sugarcane condition in Indonesia until now tend to decline where it is shown from the lack of sugarcane supply for fulfilling consumsion. During Dutch colony especially in 1930’s Indonesia became second big exporting of sugarcane in the world. Whereas now Indonesia become the second importing countries of sugarcane in the world. The upset condition is caused by several reasons such as: (a). Prime Bud are not available at the period time of planting, (b). Quantity of Prime Bud are not enough in order to supply the farmers need, (c). Quality of Prime Bud are not good enough according to local condition, (d). Price of Prime Bud is quite high in such away that farmers are not able to buy according to foarmers economic condition, and (e). Farmers have difficulties to access Prime Bud. Through development of sugarcane Prime Bud it will support significant incrase of sugarcane production and furthermore it will lead to sugarcane self sufficiency in Indonesia.

The objective of the research was to investigate the effect of root fertilizers NPK (Nitrogen, Phospor, and Potassium) combined with leaf fertilizer (Multimikro) and Growth Regulating Substance (Ethrel) to the vegetative growth of pepper plants. Theresults of the research showed that the use of root fertilizers NPK (dosage: 2.5; 5.0; and 10.0 g/plant) increased the plants height of 12,0 cm, 19,8 cm, and 23,1 cm respectively. The use of root fertilizers NPK (dosage: 2.5; 5.0; and 10.0 g/plant) combined with leaf fertilizer Multimikro (dosage 1.5 ml/l) increased plant height significantly 15.4 cm, 23.3 cm, and 26.9 cm respectively. Moreover, the use of root fertilizer NPK (dosage: 2.5; 5.0; and 10.0 g/plant) combined with Growth Regulating Substance Ethrel (dosage 1.5 ml/l) increased the vegetative growth of pepper plants significantly to a high of 18.4 cm, 28.4 cm, and 32.5 cm respectively. Conclution of the research indicated that the combination between NPK fertilizer and Ethrel was better than the combination between NPK fertilizer and Multimikro to the vegetative growth of pepper plants.

The objective of the research is to know the effect of using biomass and combinationÃ‚Â between biomass and dolomit to the land fertility with regard to corn production. TheÃ‚Â research used Complete Randomized Design with One Way Analysis of Variance,Regression, and Correlation in order to know the effect of treatment to the land fertility.The research was carried out in Wonoharjo Village, Unit VIII Kuro Tidur TransmigrationÃ‚Â area, Bengkulu, during three planting seasons from 2003 to 2004. The results of theÃ‚Â research showed that biomass from prunning of the hedgerows Flemengia congestaÃ‚Â was significant to land fertility through improvement of nutrients availability, increasingÃ‚Â pH, decreasing availability of aluminium (Al). The effect of biomass treatment into theÃ‚Â soil to a high of 5.0 ton/ha will increase average corn production from 22.256 kw/haÃ‚Â (dry grain) to 37.433 kw/ha or increase 68.19 %, whereas the effect of organic matterÃ‚Â 5.0 ton/ha combined with dolomit 2.5 ton/ha will increase average corn production fromÃ‚Â 22.256 kw/ha to 47.611 kw/ha or increase 113.92 %. The effect of biomass 10.0 ton/haÃ‚Â combined with dolomit 2.5 ton/ha will increase average corn production from 22.256kw/ha to 50.789 kw/ha or increase 128.20 %.

The effort to discover alternative source of energy in the world is still continued because the dependency from the fossil fuel should be aleviated. Since the energy crisis in 1973, the problem of energy become world hudge intention. In every energy crisis, the price of oil increase sharply and cause lack of stock. Therefore, several countries are trying to diversificate their source of energy. One of the alternative energy is biogas. The biogas can be produced from livestock waste. Through the fermentation processing of livestock waste, it can be produced biogas and the other side product and effect from this processing are: organic fertilizer, animals feeding, and prevent pollution. With the several benefits can be taken from the fermentation of livestock waste, the usage of livestock waste become biogas is necessary to be disseminated in Indonesia, where most of people are living in rural area and depending their livelihood on agriculture.

The role and function of Cimanuk Watershed tend to declining, where total of critical areaÃ‚Â reach to a high of 131,384 ha from the total of 358,400 ha or about 36.6 %. In wet seasonÃ‚Â debit of Cimanuk River reach 1,004 m3/second and in dry season reavh 4m3/second.Therefore the Debit Ratio of Cimanuk River reach to a high of 251, it is indicate thatÃ‚Â Cimanuk Watershed become very critical condition and need appropriate managementÃ‚Â especially in the upper watershed. One altervative of the watershed managementÃ‚Â is application of Alley Cropping system. The biomass from prunning of hedgerowsÃ‚Â Flemengia congesta have significant effect to land fertility through improvement ofÃ‚Â nutrients availability. Furthermore, the successful application of Alley Cropping system willlead to conserve land and water where it will support flood control, agricultural irrigation,fisheries development, electric generation, industrial development, etc.Keywords: agricultural, alley cropping, land conservation, watershed

The population density of natural agarwood (Aquilaria beccariana) in Indonesia decreased to less than one tree per hectare. Efforts have been carried out on ex situ conservation of agarwood despite facing many obstacles. In vitro propagation is one alternative to speed up the recovery of natural agarwood populations. The purpose of this study was to obtain optimal elongationÃ‚Â media for in vitro culture with addition of auxinÃ‚Â and cytokinin, namely IBA, BAP and kinetin. The results showed that the best auxin-cytokinin combination was IBA 0.1 mg/L and BAP 0.05 mg/L. This combination increased the height and number of segments of A. beccariana with an average height of 1.64 cm and average number of sections of 6.40. It is suggested that this combination of IBA and BAP was the most effective compared to the other treatments. In addition, the combination of IBA 0 mg/L and BAP 0.03 mg/L gave rise to the best response to increase the number of shoots with an average of 1.91 shoots.Keywords: Aquilaria beccariana, shoot, elongation, auxin, cytokininÃ‚Â ABSTRAKKepadatan populasi gaharu (Aquilaria beccariana) alam di Indonesia kurang dari satu pohon per hektar. Upaya pelestarian gaharu ex situ telah banyak dilakukan tetapi masih banyak kendala. Perbanyakan gaharu in vitro merupakan salah satu cara alternatif untuk mempercepat pemulihan populasi gaharu alam. Tujuan penelitian ini adalah untuk memperoleh media elongasiÃ‚Â yang optimal pada kultur in vitroÃ‚Â gaharu dengan penambahan kombinasi zat pengatur tumbuh auksinÃ‚Â dan sitokinin. Pada penelitian ini digunakan auksin IBA, serta sitokinin BAP dan Kinetin. Hasil penelitian elongasi diperoleh kombinasi auksin dan sitokinin terbaik yaitu, IBA 0,1 mg/L dan BAP 0,05 mg/L. Kombinasi ini meningkatkan tinggi dan jumlah ruas Aquilaria beccariana dengan tinggi rata-rata sebesar 1,64 cm dan jumlah ruas rata-rata sebesar 6,40 ruas. Pada kombinasi dan taraf ini diduga mekanisme kerja IBA dan BAP paling efektif dibanding perlakuan yang lain. Sedangkan kombinasi IBA 0 mg/L dan BAP 0,03 mg/L memberikan respon terbaik terhadap peningkatan jumlah tunasÃ‚Â dengan rata-rata sebanyak 1,91 tunas.Kata Kunci: Aquilaria beccariana, tunas, elongasi, auksin, sitokinin
