Abstract

ABSTRACT      This study aims to test technically the corn seeds planter (Zea mays L.) type TP CSM (Corn seeding machine) 15 using the hand tractor as a pulling device on the plot of the land 30 m x 10 m. The test results of TP CSM 15 corn seeds planter in 30 m x 10 m plot of the land on 3 field tests with soil treatment got the average effective field capacity of 0,30 ha/hour, the average theoretical field efficiency of 0,47 ha/hour, and the average field efficiency of 64,20 %. The average distance between planting rows is 73,2 cm and the average distance in row planting is 28,4 cm. The number of seeds per planting hole 1 – 3 with an average of 1 seed per planting hole and an average planting depth of 5.5 cm. The percentage of seeds which grew successfully by an average of 75,74% and the percentage of seeds which unsuccessfully to grow by an average of 24,26%. Keywords : TP CSM 15, Hand Tractor, Field Efficiency.

Abstract

ABSTRACT Chili plants are an agricultural commodity with great potential in Indonesia. The price of agricultural products is greatly influenced by the availability of materials in the market if the available goods are much less than the demand, the price will soar and vice versa. Therefore, to maintain chili peppers so that they can last for a long period of time it is necessary to carry out preservation in the form of drying. The temperature distribution during the drying process of cayenne pepper starts from the highest air temperature of each shelf, namely 13:00 with a temperature of 55,100C material temperature at 13:00 with a temperature of 55,400C, a collector temperature at 13:00 with a temperature of 63,800C and an ambient temperature of 360C. Air humidity greatly affects the drying process. The process of observing 46-hour air humidity, relatively low humidity occurs at 35 o'clock with the lower shelf hovering around 21.30%, the middle rack hovering around 14.30% hour to 46, the upper rack hovering around 13.40% while the environmental Rh hovering around 57.90% at 20 o'clock. The length of time for drying cayenne pepper using a rack-type hybrid dryer takes a span of 36 hours with the moisture content of cayenne pepper material on shelf 1 of 7.14%, shelf 2 of 7.14% while shelf 3 of 14.04%. The drying rate of cayenne pepper lower shelf, middle rack and upper rack is 11.61%/hour, 11.61%/hour and 2.91%/hour, respectively.
