Abstract

The objectives of the research are to evaluate the suitability of land for sugarcane growth and give recommendation through land fertilization for optimal sugarcane cultivation. Furthermore, the impacts of this action are to increase the planting area of sugarcane and productivity. The research use GeographicalInformation System (GIS) in Tulungagung Regency, starting from June until October 2004. The results of the research showed that the suitable, conditionally suitable, and not suitable land for sugarcane cultivation in Tulungagung Regency reach to a high of 45,651 ha, 61,547 ha, and 6,038 ha respectively. Based on the soil condition with low contents of N, P and K, the dosage calculation of N, P, and K fertilizers for optimal sugarcane cultivation reach to a high of: N (ZA) = 500 kg/ha, P (SP-36) = 215 kg/ha, and K (KCl) = 260 kg/ha.

Abstract

The objectives of the research are to know the description of sugarcane enterprise especially concerning with coat and income, to know the sugarcane practice as a guide to farmers within their enterprise, and to increase input guarantee of raw material to sugarcane factory. The research was carriedout through gathering primary data by using questionaire with farmers as respondents. The respondents were selected by method of Stratified Purposive Random Sampling. The field survey was done in Bondowoso Regency, from 24th August untill 7th September 2004. The data was analyzed by using: hypothesis testing, break even point analysis, and sensitivity analysis. The results of the research show that the average of net farmers income from new planted sugarcane reach to a high of Rp. 4,507,584,-/year whereas from ratoon sugarcane reach to a high of Rp 3,272,307,-/year. The recommendation for sugarcane self sufficiency is by using productive arid land especially in Java with optimally agricultural inputs and cultivate according to standard operational procedure.

Abstract

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.

Abstract

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.

Abstract

The objectives of the research were to make land suitability map for sugarcane plant (Saccharum officinarum), to give recommendation of location including area for sugarcane plant cultivation and to increase sugarcane plant productivity. The research used maps overlay and Geographical Information System (GIS) which used Arch-View Spatial Analysis version 2,0 A in Remote Sensing Laboratory, Agency for the Assessment and Application of Technology (BPPT), Jakarta. The research was carried out in Tegal Regency starting from June to October 2004.The results of the research showed that the suitable, conditionally suitable, and not suitable land for sugarcane cultivation in Tegal Regency reached to a high of 20,227 ha, 144 ha, and 81,599 ha respectively. There were six most dominant kind of soil: alluvial (32,735 ha), grumosol 5,760 ha), mediteran (17,067 ha), latosol (18,595 ha), glei humus (596 ha), and regosol (22,721 ha).

Abstract

The objective of the research is to know the optimal formula of auksine and sitokinine in the Murashige dan Skoog (MS) basic media and to conserve gaharu tree (Aquilaria beccariana) in order to produce young gaharu plants which have similar properties with their mother plants. The research used Factorial Design with basic analysis of Complete Randomized Design in order to know the effect of treatment to the elongation. The results of the research showed that after 8 weeks of the treatment with IBA and the combination with BAP and Kinetin have significant effect to the increase of height and number of segment but have no significant effect to the number of buds. The combination of 0.1 mg/l IBA and BAP 0.05 mg/l was the optimal formula for the elongation of young gaharu plants with the increse of height 1.7 cm and number of segmnent 6.4.
