ABSTRACT
Objective of the research was to determine the dose of nitrogen (N), phosphorus (P) and Potassium (K) fertilizers for lowland and upland paddy at Production Center (KSP) of Food Crops in Tana Tidung Regency.
The research carried out for three months starting from October to December 2010.
in Tana Tidung Regency at 16 KSP spread over three sub districts, namely: Sesayap, Sesayap Hilir, and Tana Lia.
The study uses survey methods to obtain a composite soil samples, soil samples are then analyzed in a laboratory, next analyzed further using the assessment criteria of the soil chemical status Soil Research Center (PPT). Fertilizer demand in the study location is determined based on crop nutrient needs and the ability of soil to provide nutrients (indigenous supply) or the available nutrients in the soil.
Results of the research sindicated that: (1) the availability of N in the study sites are generally quite low, P availability is low to very low, while the availability of K are generally classified as moderate to very high, (2) most of the research sites require fertilizer N, P and K with the dose depends on the type of commodity and research sites, (3) for lowland rice, 9 of 16 research sites require N fertilization with a dose of 5-31 kg N ha-1 or 11-67 kg ha-1 urea, all study sites require P fertilization with doses of 25.0 to 57.8 kg ha-1 P2O5 or 69-161 kg ha-1 SP-36 and 11 of the 16 research sites require 8-52 kg ha-1 K2O or 13-87 kg ha-1 KCl;
and (4) for upland rice, 14 of 16 study sites require a dose of fertilizer N with 12-76 kg N ha-1 or 26-165 kg ha-1 urea, all study sites require P fertilization at a dose of 5.2 to 27, 8 kg ha-1 P2O5 or 14-77 kg ha-1 SP-36, while for K does not need added fertilizer due to the availability of N, P and K in the soil are sufficient to support optimal growth of paddy fields.

ABSTRACT
Objectives of the research were (1) to study the effect of TGHF on the growth and production of two soybean varieties; and (2) to find out the proper TGHF dosage and suitable variety for soybean.
The research was carried out in Muang sub-village of Lempake Urban Village, North Samarinda Sub Municipality of Samarinda Municipality. It lasted for four months (March to July 2010). This research employed Randomised Block Design with factorial 2 x 4 and 4 replications.
The first factor was soybean variety (V), consisted of 2 sub factors: Grobogan variety (v1), and Ijen variety (v2). And the second factor was application of Tiens Golden Harvest Fertilizer-TGHF (T) that consisted of 4 sub-factors: no TGHF application (t0), 2.5 ml TGHF per liter water (t1), 5.0 ml TGHF per liter water (t2), 7.5 ml TGHF per liter water (t3).
Results of the research revealed that: (1) Soybean variety affected significantly to very significantly on plant height at 30 and 45 days after sowing, age of plant flowered and harvested, number of pod per plant, seed number per pod, weight of 100 dry seeds, and dry seed production, but it did not affect significantly on the plant height at 15 days after sowing, percentage of pod seeded, and plant dry weight. The highest production of dry seed was attained on v2 treatment with 1.38 Mg ha-1, meanwhile the v1 treatment was only 1.14 Mg ha-1; (2) The application of TGHF was not different significantly on all parameters observered; and (3) The similar effect was also founded on the interaction between soybean variety and TGHF treatment.

ABSTRACT
This study aims to determine the land suitability class and improvements to the development of lowland paddy and upland paddy farming.
Field surveys carried out by making a mini profile (1.2 x 1.2 x 1 m) as a morphology property sample at a depth of 0-30 cm and 30-60 cm, while the drilling is done around the mini-profiles with the composite method (8 points) for analysis of soil physical/chemical properties. Data obtained were analyzed using standard criteria of the Soil Research Institute, Center for Research and Development of Land and Agro-climate, Ministry of Agriculture in 2003 that uses the criteria of land quality including temperature, water availability, oxygen availability, rooting media, nutrient retention, sodicity, erosion and land preparation. Each quality of land divided into several land characteristics that are used as a benchmark to assess the characteristics of the land so that land can be known to some limiting factors on rice paddy fields to be developed.
The survey results indicated that the actual land suitability classes are marginally suitable (S3) for both, lowland and upland paddy, however it can be improved through the efforts of improvement with the addition of organic matter, fertilizing, liming, making drainage, and terracing so it could be improved its land potential become quite suitable (S2).

9 ABSTRACT
Sand is a type of loose soil and susceptible to permeability, soil permeability embankment easy and very good experience for the type of work etc. Embankment road in this research, to find the permeability of each sample so that later can be used as a reference in the field of work that meets the specifications.
From the research one kind of sand samples obtained with long time experience of permeability t = 300 sec, with the remaining volume of collected Q2 = 260 ml, and the value of permeability coefficient k = 0.004035 cm/sec.
For research on soil samples to the second type soil embankment obtained with long time experience of permeability t = 1500 sec, with the remaining volume of collected Q2 = 130 ml, and the permeability coefficient value k = 0.00400 cm/sec.
To study the sample to the third type of sand and clay soil obtained with long time experience of permeability t = 4980 sec, with the remaining volume of collected Q2 = 170 ml, and the permeability coefficient value k = 0.00016 cm/sec.
To study the sample to the fourth type of clay obtained with long time experience of permeability t = 5040 sec, with the remaining volume of collected Q2 = 150 ml, and the permeability coefficient value k = 0.00014 cm/sec.
Seen from figure, the clay has value coefficient k = 0.00014 cm/cm is very small so that the land is not fit to be used for the job embankment roads, embenkment retaining wall, etc. Proper land use type is the type of soil embankment having high permeability coefficients and meet specifications.

ABSTRACT
The purpose of this study was to determine the effect of plant spacing and concentration of organic fertilizer on the growth and production of onion in the lowland Samarinda in East Kalimantan.
The experiment was conducted from May to September 2011 at the South Sempaja Urban Village of North Samarinda Sub-district, Samarinda.
The design used was Randomized Design Group (RGD) with 4x4 factorial experiment with three replications. The first factor was the plant spacing (A) consisting of:
J1 = 10 cm x 15 cm, J2 = 15 cm x 15 cm, J3 = 15 cm x 20 cm, J4 = 20 cm x 20 cm. The second factor was the concentration of Nasa fertilizer (P) consisting of: P0 = 0 ml/liter water, P1 = 1 ml/liter water, P2 = 2 ml/liter water, P3 = 3 ml/liter water. Data were analyzed using analysis of variance, if the analysis shows the significant effect, then continued with the Least Significant Differences Test (LSD) standard of 5%.
The results indicated that: (1) the effect of different spacing is very significant on plant height at 20 and 60 days after planting, leaf number at 40 and 60 days old, and tuber production. The best treatment attained by the spacing of 15 cm x 15 cm with a tubers production potential of 11.72 tons/ha; (2) the effect of Nasa liquid organic fertilizer was very significant on plant height, number of tillers, number of leaf age at 20, 40 and 60 days after planting and tuber weight per plot and production ton/ha. The best treatment was attained by a concentration of 2 ml/l water with the tuber potential weight per plot and production of tubers in a row at 1.78 kg/plot and 7.67 tonnes/ha; and (3) the effect of the interaction between plant spacing and concentration of Nasa liquid organic fertilizer were not significant on all parameters observed.
