Penentuan Nilai Tukar: Pengujian Purchasing Power Parity di Indonesia

This paper provides a test of purchasing power parity (PPP) as an explanation for longtermforeign exchange rate movement. We impose symmetry and proportionality restrictions ofPPP to data drawn from the period 1969.1 through 2001.4. The tests are also run for sub-periods. Symmetry and proportionality restrictions find little support for the unit root tests though the Johansen test suggests that foreign exchange rate and inflation rate are linked in a long run sense. Error correction models are then estimated on the basis of the assumption that the United States inflation rate is exogenous. The error correction models result also rejects the PPP

Describing the Height Growth of Corn Using Logistic and Gompertz Model

This paper is about a critical study on corn (Zea mays) plant with a non linear approach, as it is slowly growth rate at the initial stage of the cycle, followed by a rapid growth stage to a critical point then the height growth rate began to decline, reaching to a stability phase. The purpose of this research is to develope such a model to fit the height growth of corn (Zea mays) plant given microbe combination of Ochrobactrum sp.and Bacillus megatirium treatment; besides, to compare the plant absolute growth rate model between plant with microbe and non microbe treatment . A simple sigmoid model is preffered as it is easier to interpret the parameters biologically. The result shows that Logistic model is better fit in describing the height growth compare to Gompertz model, as it yields coefficient of determination is more than 99%. This model shows that the maximum height growth rate happens in about 40 day after planting. Based on the model, it showed that the absolute growth rate tend to be bell-shaped and right-skewed for Logistic and Gompertz respectively

Integrated Farming Model of Small Ruminants in Deli Serdang, North Sumatra - Indonesia

This research was done to measure the added value of goat and sheep with cut and carry systemand influencing factors of goat/sheep productivity and to measure the added value of manure to palmproductivity. The research was done in Deli Serdang Regency by determining two districts as researcharea: Tanjung Morawa District and Bangun Purba District. Location was determined by purposivesampling technique based on population of small ruminants and area of oil palm plantation in bothdistricts.
