Serapan Phospat dan Pertumbuhan Bibit Kelapa Sawit pada Tanah Ultisol Akibat Cendawan Mikoriza Abuskula Made Same
Jurnal Penelitian Pertanian Terapan Vol 11 No 2 (2011)
Publisher : Politeknik Negeri Lampung.

One of the disadvantages of oil palm development is the limitedness of fertile soil. A constraint faced by both big plantation and small holders is the high cost of crop maintenance. Around 60% of the total crop maintenance is used for fertilizing the crop. This study aims at finding out phosphate absorbtion and the growth of oil palm seedling with the addition of Arbuscullar Mycorrhizal Fungi (AMF) and different dosages of phosphate fertilizer. A factorial Complete Randomized Design with three replications has been used. The first factor was the addition of AMF consisting of three levels: M0=0 g AMF polybag-1, M1=5 g AMF polybag -1, and M2 = 10 g AMF polybag -1. The second factor was the addition of four levels of phosphate using TCP-36: P0= 0 g TCP-36 polybag-1, P =15 g TCP-36 polybag-1, P2=30 g TCP-36 polybag-1, and P3=45 g TCP-36 polybag-1. Results showed that the Application of 10 g AMF polybag-1was able to increase P-absorbtion and the growth of oil palm seeding such as fresh crown weight, dry crown weight, fresh root weight, dry and root weight. Application of 45 g TCP-36 polybag -1was able to increase the growth such as plant height, dry crown weight, fresh root weight, and dry root weight. Keywords: Arbuscullar Mycorrhizal Fungi, phosphate, and oil palm

The aim of this research is find out the lactic acid bacteria (LAB) from peda, bekasam, terasi and rusip which had antagonis by Morganella morganii (histamin producer bacteria). The result was that the number isolate from peda was 3 (1P1 104, 3P1 104, 2P2 104), bekasam was 7 (1B1 104, 2B1104, 1B2104, 2B2104, 3B2 104, 1B1 105, 2B1105), terasi was 4 (1T1 104, 2T1 104, 3T1 104) and rusip was 5 isolates (1R1103, 2R1103, 3R1103, 1R1104,Â 1R2104). All the isolates was bacill, gram positive, and negative catalase. The isolate which had biggest of clear zone was 3B1104 and 1T11104, with the diameter of clear zone was 1.725 cm and 1.300 cm.

Role of cassava in the national economy continued to decline because it is not a priority commodity. As a result, crop acreage is declining and productivity did not increase significantly. This situation also occurred in West Sumatra Province. The cause is not yet precise technology to increase the income of cassava farmers and the diversity of the community's ability to adjust the pattern that has been owned by the available land resources. Meanwhile, demand for cassava will continue to increase along with the continued rise and soaring fuel prices (fuel) in the world market for cassava is one source of bio-ethanol to substitute a premium. This article contains about the problems of cassava and technological support for the development of cassava in West Sumatra. The methodology of writing a book study (literature) on cassava commodity that comes from books, proceedings, journals, papers and others. As a result, the development of cassava in West Sumatra to be directed mainly on dry land agroecosystem. Based on the type of climate and land type, almost all areas in West Sumatra has the potential to be developed as a regional center for cassava production.To improve cassava production strategies are needed, among other things: (1) The addition of harvest area, and (2) Intensification of quality improvement. Addition of harvest area include: (a) opening of a new land, (b) multiple cropping, and (c) increase harvest index. While improving the quality of intensification can be done with the application of several alternative technologies in cultivation, among others: (1) high yielding varieties, (2) preparation of seedlings, (3) land preparation, (4) planting, (5) fertilization, (6) plant maintenance; and (7) harvest. Results of analysis of farming cassava variety Darul Hidayah show farmers the benefits of Rp. 34,110,000, - for 12 months and R/C ratio value = 3.46. Keywords: cassava, technology, dry land, culture, West Sumatra.

The research on The Effect of Providing Curcuminoid Dosage To Digestible protein, Protein Efficiency and The Rate of Passage of Feed in Grower Period Pigâ€™s Digest System has been conducted since January 10th, to 27thFebruary 2008, at Pig Livestock Laboratory and Teaching Farm of KPBI Obor Swastika in Cisarua, Bandung, Indonesia. The aim of this research was to state the effect of providing and the best dosage of curcuminoid in meal to digestible protein, protein efficiency and the rate of passage of feed in grower period pigâ€™s digest system. This research used 20 grower period pigs with 35 kg average body weight and 2,13 percent variation coefficient. The experiment used the completely randomized design, the treatment given was the addition level of curcuminoid dosage (0, 4, 8 and 12 mg curcuminoid/kg body weight). Each treatment was done five times. The result of this research gives 4 mg curcuminoid/kg body weight give in ration finisher pig increase protein digestability and no significant for protein efficiency and passing rate feed Keywords : Curcuminoid, Digestible Protein, Protein Efficiency, Rate of Passage of Meal in Digest System, Grower Period Pig

Change in rice market from controlled market to free market cause domestic rice price is exposed more to market fluctuation. This circumstance directly affects competitiveness of domestic rice farm business. This paper is aimed at assessing competitiveness of rice farm business. The results showed that rice farm business competitiveness was very sensitive to yield decrease, world price of rice, and change in rupiah exchange rate. Strategic attempt to do is to improve efficiency of rice farm business through (a) application of specific technology for specific locations, (b) balance of inputs use, (c) improvement of inputs and output market institution, and (d) farm business management improvement.

Leafminers, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) known as main pest at vegetable and ornamental crop. Hemiptarsinus varicornis (Girault) (Hymenoptera: Eulophidae) is one of ectoparasitoid larvae of L. huidobrensis that usually find in the field, however the levels of parasitism at field relative lower. Therefore we need the conservation technology of parasitoid in order to its population overflow so that its performance increases. Rorippa indica (L) have potential as reservoir of parasitoid H. varicornis, so that can be used as conservation medium of H. varicornis. Planting weeds R. indica among of chickpea crop, can decraese the population of adult and larvae L. huidobrensis significantly, increase adult population H. varicornis and larvae population L. huidobrensis parasitism by H. varicornis. Growth rate of population adult H. varicornis at block without weeds R. indica follow the pattern of regretion equation Y=0,1312Xâ€“0,2246 and Y=0,7172X+1,1 while at the block planted weeds R. indica. Growth rate of larvae population L. huidobrensis at block without weeds R. indica follow the pattern of regretion equation Y=0,9315Xâ€“0,9835 and Y=0,8647X+1,0875 while at the block planted weeds R. indica. Weeds R. indica can be used as reservoar parasitoid H. varicornis in the effort the conservation parasitoid. Keywords: Biological control, Leafminer, Liriomyza huidobrensis, conservation technology reservoir parasitoids, Hemiptarsinus varicornis
