Abstract

This study aims to analyze the factors that influence rubber production and to  analyze the efficiency of the price of rubber production. The variables examined in this study include the efficiency of the use of rubber production factors, the Cobb-Dounglas production function is unsed, Classic Assumption Test, Statistical Test and Allocative Efficiency. The test results on the production factors show that the variable area of land.Labor, fungicide had a significant effect on production. NPK fertilizer and length of farming had no significant effect on rubber production. The results of the allocative efficiency analysis showed that the use of land area, labor and fungicides was inefficient in rubber cultivation in Ambawang district, Kubu Raya Regency.

Abstract

This study aims to study the differences in the physical properties of peat soils in rubber and oil palm plantations in Rasau Jaya III Village Rasau District Kubu Raya District. The parameters of this study are, peat depth, peat maturity, measurement of ground water level depth, content weight, water content capacity field, total porosity, permeability, and some chemical properties, peat soil in people's rubber and oil palm plantations in Rasau Jaya District, Kubu Raya Regency.  Measurement of peat depth is taken up to the mineral soil boundary, has a 74 cm rubber peat depth and 66 cm oil palm. The level of maturity of both fields at the sapric level. The water resistant surface on rubber land is 70 cm and oil palm land is 58.8 cm. Average bulk density of depth 0 – 30 cm rubber land 0.34 g/cm3, palm 0.31 g/cm3. Depth 30-60 cm rubber 0.28 g/cm3, palm 0.38 g/cm3. Average field water capacity depth of 0-30 rubber fields 74, 63% palm 85.19%. While at a depth of 30-60 cm rubber land has 71.58% oil palm area of 84.58% vol. The average porosity of total soil depth of 0-30 cm palm oil is 86.96% higher than rubber area 82.37%. The average total porosity of soil at a depth of 30-60 cm is lower oil palm 81.82% rubber land 86.82% and both lands are classified as very porous criteria. The mean permeability values based on the t-test results were not significantly different.

Abstract

Paddy production at Sedau Village are improving caused by land characteristics. Then the carrying capacity would be counted by it correlation between the amount population and paddy productivity each year. The object of the research are to identify soil characteristics, determine cluster type and the carrying capacity of rice fileds in Sedau Village. The research method is soil survey, soil sample analysis, multivariate regression analysis, cluster analysis and the analysis of the carrying capacity. The results showed, variables affecting rice production were Bulk Density, Permeability, P-available and K-exchangeable. If Soil Bulk Density and Permeability are increased, so the paddy production will decrease. If P-available and K-exchangeable are increasing, so the paddy production will increas too. Following the formula: Y=1.605 – 0.783X1 – 0.367X3 + 0.005X11 + 9.206X12 + error. The research site consisting of 6 Land Mapping Units (LMU) is divided into 3 clusters. Cluster 1 consisting of LMU 3 and LMU 6, Cluster 2 consisting of LMU 2, 4 and 5, Cluster 3 only contains LMU 1. All clusters are classified as carrying capacity Class III, that means rice fields in each clusters has not been able to food self-sufficiency.

Abstract

This research was conducted to determine the carrying capacity of agricultural land in Kubu Raya Regency. The research method used in this research is the survey method, the determination of the research location is done intentionally (purposive). The data collected in this research is secondary data. The method of data analysis using the analysis of Odum, Christaller, Ebenezer Howard and Issad in Moniaga, 2011. The results showed that, Kubu Raya District is capable of self-supporting food but has not been able to provide a decent life for its residents Kubu Raya Regency can still be self-sufficient but unable to meet the needs physical population. Therefore, these problems must be overcome. This is done by applying sustainable agriculture and appropriate land use by treating it as needed, so that the soil is not damaged and can guarantee high productivity.

Abstract

The Effect Of Various Concentrations Of Liquid Organic Fertilizer From Goat's Urine On The Growth Of Growth Of Areca Plants (Areca Catechu, L.).  Betel palm (Areca Catechu, L.) is one of the plants that has various benefits ranging from health, care, to coloring. The purpose of the study was to determine the effect of giving goat urine liquid organic fertilizer on the growth of areca nut plants. This study used a non-factorial randomized block design (RAK), with 5 treatment concentrations and replicating 4 times, namely: Po: 0% (0 ml poc + 1000 ml water), P1: 5.0% (50 ml poc + 950 ml water), P2 : 10% (100 ml poc + 900 ml water), P3 : 15% (150 ml poc + 850 ml water), P4 : 20% (200 ml poc + 800 ml water), with fertilizer spray method liquid organic as much as 50 ml/plant every 1 week. Parameters observed were plant height (cm), number of leaves (strands), stem diameter (mm). The results of this study showed that giving urine liquid organic fertilizer for P1 treatment had a significant effect on the number of leaves at 5 Mst, namely 2.10 leaves.

Abstract

Utilization of Ultisols for sweet maize cultivation has several barriers, especially low of soil acidity, CEC, nutrient availability, organic matter and high of Al, Fe, and Mn consentration. This research was aimed to know the interaction of palm oil empty fruit compost and cockle shell ash on phosphorus uptake and yield of sweet maize in Ultisols. The experiment was carried out in screen house of Agriculture Faculty, Tanjungpura University. The research used factorial design arranged in a completely randomized design (CRD) consisting of two factors treatment (CRD). The first factor is palm oil empty fruit compost consisting control (T0), 670 g/polybag (T1), 1,030 g/polybag (T2) and 1,410 g/polybag (T3). The second factor is cockle shell ash consisting (A0), 3,3 g/polybag (A1), 4,4 g/polybag (A2), and 5,5 g/ polybag (A3). Each tretments was done in 3 replication. The parameters are soil pH, C-Oraganik, P-Available, phosphorus uptake, cob length, and cob weight. The results showed T0A3 can increase soil pH highest with the value 6.08. T3A2 can increase C-Organic with the value 2.31. T2A1 can increase P-Available with the value 26.96. T2 (1,030 g/polybag) significantly affected phosphorus uptake and cob weight.

Abstract

Maize (Zea may ssaccharata) is the horticulture in demand current society this. Limited avalability of land productive agriculture causes agricultural development, especially maize plant using peat soil media. Peat soil are low acidity, and nutrient content macro N, P, K available to plant also low. Attempts made for increasing the productivity of peat soils is by giving biochar and proper fertilization. Provision of biochar and inorganic fertilizer in addition to being a source of nutrients for plants, can also improve the physical, chemical and biological properties of the soil. This study aims to determine the influence of the application of coconut shell biochar and inorganic fertilizers on N P K nutrient uptake and maize crop yields. Research using Complete Random Design (CRD) factorial consists of two factors treatment and three replications. The first factor, namely coconut shell biochar which consist of 3 levels. The second factor, namely inorganic fertilizer consisting of 3 levels so there are 27 experimental units consisting of 2 sets of plants. Based on the results of variance, interaction of coconut shell biochar administration and inorganic fertilizer no significantly influence on all treatments. Whereas the administration of coconut shell biochar has no significant influence on soil pH, K uptake and cob weight, but significantly affected the wet weight, dray weight, N uptake and K uptake. Inorganik fertilizer has no significant influence on soil pH, wet weight, dry weight, N uptake and cob weight, but has a significant influence on P uptake and K uptake. The best cob weight is at A1B3 treatment (biochar coconut shell 55 gram/polybag + inorganic fertilizer 5,1 gram/polybag).
