Prospek Dan Kendala Pengembangan Jarak Pagar (Jatropha Curcas L.) Sebagai Bahan Bakar Nabati Di Indonesia

Prospects and Problems of Jatropha curcas Development as Biodiesel Energy in IndonesiaOne of potential commodities to be used as bio fuel in Indonesia is Jatropha curcas. This plant is chosen because it does not compete with food crops, while animal do not like it because it is poisonous. Moreover, this plant is adaptable in different climate conditions and may become a new business opportunity for farmers, since fuel production activities can be decentralized. There are 14.2 million hectares of land suitable for growing the plant, whereas currently only 5 million hectares are available. Indonesian Centre for Estate Crops Research and Development nowadays has superior varieties that can be used to support expansion of 2.4 million hectares of jatropha plantations in 2025. However, agriculture technologies still have to be improved in term of, for instance, pest and disease control strategies, planting patterns, as well as fertilizing, and cultivation technologies. Moreover, current seed production of jatropha is still low i.e. only 7.582 tonnes in 2007 of 68.200 hectares which becoming 7.925 tonnes in 2008 of 69.221 ha, and 8.013 tonnes in 2009 of 69.315 hectares. The main strategy to accelerate jatropha plantation areas is to find new strategy especially related to how to improve plant production. This approach may be achieved through biotechnology and plant genetic engineering as well as finding new genetic varieties from its country of origin, including countries in Latin America

VALUES OF ISLAMIC EDUCATION IN ABU UMAR BASYIER’S SANDIWARA LANGIT

The first fact that appeared on earth when Gabriel came to The Prophet for the first time was that the new religion (Islam) was based on science and rejected false beliefs and delusions as a whole. In the same manner as science, education is very important in Islam Method of teaching has very important role in education and narrating story was one of the Prophet’s methods. This narrating method was then followed by Muslim scholars and educators from earlier age till now, and one of them is Abu Umar Basyier who wrote Sandiwara Langit that assumed to have some values of Islamic education. The problem statement of this research is: “what values of Islamic education are contained in Abu Umar Basyier’s Sandiwara Langit?” and the objective of this study is to determine the values of Islamic education contained in Abu Umar Basyier’s Sandiwara Langit. This study is expected to give contributions of thought to the development of science, particularly the development of Islamic education, in the form of strengthening the theory that narrating story is a teaching method, and expected to be able to teach the general public, especially educators among the Muslims, that there are many lessons can be studied from a story and encourage Muslims educators that narrating story as one of the main educational methods. This research is a qualitative one because it produces descriptive data and it is a library and documentation research for the data observed are library texts and documents. The primary data source of this research is Abu Umar Basyier’s Sandiwara Langit.

Peran Dan Pengelolaan Hara Nitrogen Pada Tanaman Tebu Untuk Peningkatan Produktivitas Tebu

Role and Management of Sugarcane Nitrogen Nutrient to Increase ProductivityEfforts to increase sugarcane productivity requires sugarcane with high sucrose yielding potency completed by proper cultivation method. Effective and efficient N management require on understanding physiological role and its responses. This review is aimed to discuss research findings and its implication on nutrient absorption and uptake, reduction, and amino acid biosynthesis, responses and N effects and its interaction, and supply aspect such as dossage, application method in relation to productivity and sucrose content to increase sugarcane productivity and its sucrose content. Through this review will be gotten proper N management to increase sugar productivity. Nitrate uptake needs energy and nitrate reductase. It is not for ammonium, but it need excess availability promoted toxicity., Nitrate will be reduced in roots or leaves to be ammonium, and then utilize for amino acid synthesis. Nitrogen enters to plants through fertilizer as nitrate or ammonium with other ion in fertilizer such as sulphate ammonium, chlorida ammonium, nitrate ammonium, nitrate calsium, and also urea. Proper N application wiil raise vegetative growth (LAI and tillering), photoshynthetic rate, flowering delay, lodging, and productivity rise. Response on N depend on N form and its pairs. N fertilizer dosage lower than 150 kg N/ha recomended once, at early growth phase, but dossage the higher one, supplemental application at 3 months. Right N dossage is significantly increasing sugarcane productivity, but its effect on sucrose content generally is not significantly

The constrain of lemongrass cultivation is crop nutrient requirement does not estimate yet as a reference for determining the dosage of fertilizer needed to produce good yield and quality. The study aims to determine the NPK uptake of seven lemongrass promising numbers grown in latosol soil in Cibinong research garden, Bogor, namely: Cyci 0003, 0004, 0006, 0009, 0012, 0018 and local. Seven lemongrass promising numbers were from Boyolali, Yogyakarta, Cipatat, Cisaroni, East Nusa Tenggara, Bogor, and Cibinong which had been characterized. The design used was randomized block design with four replications and 25 plants per plots. The parameters observed were number of tillers, plant height, leaf length and width, stem diameter weight per clump, oil yield and quality, and chlorophyll content. The results showed that there were differences of nutrient uptake pattern, as well as the amount of fertilizer requirement N, P and K on all seven promising numbers of lemongrass. Local and Cyci 0003 had highest oil and sitral production compared to other lemongrass promising numbers. To generate the essential oil yield 81,39 kg ha-1 and production of citral 14,25 tonnes ha-1, Cyci 0003 absorbed 284,65 kg Urea, 49,15 kg SP-36, and 308,95 kg KCl ha-1, while local Cyci absorbed 230,29 kg Urea, 49,97 kg SP-36, and 161,8 kg KCl ha-1 to produce 97,94 kg essential oils yield ha-1 and 16,01 tonnes citral ha-1. Essential oil content of Lemongrass increased with increasing uptake of N and P, and citral oil content increased with increasing nutrient P uptake. Local Cyci promising number was relatively efficient in N, P, and K nutrient absorption
