Randomize Complete Design (RCD), Randomize Complete Block Design (RCBD) and Randomize Complete Factorial Design (RCFD) are instruments of statistical analysis.  It is  effective and efficient to run those analysis designs using computer statistical program as MSUSTAT, SPSS, and SAS.  The designs are usually used to analysis  the data of experiment on Livestock, Fishery, Food Crops, Medical Health, Psychology  and industrial manufacturing. Application of experiment design in RCD, RCBD and Factorial Analyzed was two treatments and four replicates to chieck’s body weight, crop, gizzard, prov, duod, jejun, ileum and sec as parameters. The first treatment was ration aided 25 percent concentrate and  ration aided 50 percent concentrate , and second treatment was male and female of chiecks.

  • Aplikasi Sistem Informasi Geografi dan �Analytic Hierarchy Process� dalam Studi Alokasi dan Optimasi Penggunaan Lahan Pertanian
Sumbangan Baja

One of the crucial stages in agricultural land use allocation is the formulation of land use alternatives which meet multiple competing objectives. In essence, such alternatives are choice possibilities that are selected a priori as candidates. These candidates may consist of a number of choice locations for siting a given land use, or land use types on specified geographical units. One of the solutions to such candidate selection is the prioritization of alternatives through the method called multiple criteria decision making (MCDM). This paper presents systematic procedures for the utilization of MCDM based on the Analytic Hierarchy Process (AHP), coupled with geographical information systems (GIS). Two main program packages were employed: IDRISI 32 (a raster-based GIS) and Expert Choice (which uses AHP principles). In the GIS-AHP interactions, the model employs a loose coupling strategy, so that some forms of data exchange mechanisms occur. In this paper, basic principles and theory of AHP were first discussed, followed by presenting two case studies. The first example is concerned with the determination of optimal proportion of farm land for different crops; and the second is focused on the prioritization of land units for a given land use. Both case studies depict a flexible way of prioritizing land use alternatives using criteria from different aspects (biophysics and socio-economic). The model presented highlights the weakness of the methods of land resource assessment, which consider only a single objective, and take no account of a strategy for prioritization of different land use alternatives from a number of feasible choices. The study also contributes to the augmentation of strategic analytical capabilities and decision support tools in agricultural land use planning and allocation.

Measurement of data distribution for selection of maize family.  In Statistical procedure there are two important of analysis for selected superior maize family i.e. central measurement (mean, median, modus) and variance.  Mean and standard deviation (s) of the sample is commonly to used and important to find for known of some characters variable of maize.  The observed of data could be also arrange in sequences system or in tabulated.  Distribution of T-student could be test for mean, Normal for selected of superior family by simultaneous of variable and c2 (chi-square) for test lay of fit like as gen segregation (Mendel law).  The central measurement of mean = åxi/n, media is focus of data and modus is value of same data.  Standard deviation (s) of the mean isÖ[1/n{åxi2 – (åxi)2/n]. The application of measurement data on central distribution and variance has been applied for selected family on nitrogen deficiency from maize population “Maros Sinthetyic-1(SI)C1”.  The experiment to conducted in Bajeng South Sulawesi in rainy season 2000/2001.  The yield data distribution of 100 families be founded means is 3146 kg/ha, median : 3021.5kg/ha and modus 3952.,2781, and 2137 kg/ha.  s = 961,1 kg/ha.  There are four family superior has been selected (yield >5.0 t/ha) are number 29, 77, 35, 9 and 20.  Gen segregation of diploid crossed could be receive of hypothesis H0 by use c2 for evaluated that number of ears is ratio 9 : 3 : 3: 1.

This paper aimed to evaluate the AARD’s  personnel data processing  through the implementation of the management information systems-personnel sub systems (MIS Personnel sub systems) developed by the AARD since 1986. The accuracy of personnel data and updating data plays an important role in producing information needed for personnel administration process and other managerial policy formulations, which required a consistent personnel database maintenance within the AARD institution units.
