Abstract

Abstract Corn (Zea mays L) is one of the cereal plants that grows almost all over the world and is classified as a species with large genetic variability. In Indonesia corn is the second staple food after rice. Besides that, corn can be used as animal feed ingredients and industrial raw materials (Fadhullah Muhammad 2016). Sieving is the separation of the mixture of solid particles that have various sizes of material using a sieve. The sieving process is also used as a cleaning tool, the separator of waste which is different in size from the raw material. The purpose of this study was to modify and technically test the corn seed cleaning system using the electro motor sway and different air flow speeds using a fan. This research has been carried out in the Agricultural Engineering Workshop, Agriculture Technology Department of the Faculty of Agriculture Unsrat for 3 months from May to July 2018, including the making of sieving tools, implementation of sieving experiments and analysis of research data. This study includes the modification and technical testing of corn seed cleaning equipment with a combination of swaying and wind blowing sieve systems, using 3 different air flow rates from different fans with 3 (three) replications, namely: 1.

Abstract

ABSTRACT Walnut trees are forest plants and have not been widely cultivated. Walnuts are native to Indonesia which are widely grown in eastern Indonesia, such as North Sulawesi, Maluku and Seram Island. This plant has the potential of economics, chemicals that are rich in bioactive content and antioxidant content with one of its components, namely polyphenols, walnuts grow in North Sulawesi where the seeds are widely used as supplement for cakes such as halua walnuts, dodol kenari, klaper koek, and others.  The results of the observation showed the temperature distribution in the plenum room, drying chamber, temperature of the material and the outside air temperature of the drying air temperature was around 60 OC there was a temperature fluctuation in the drying chamber. Moisture levels are inversely proportional to changes in time. The longer the drying, the smaller the water content of walnut seeds shows the pattern of decreasing water content in this experiment with 5 replications showing an exponential pattern. The drying time of walnut seeds using this dryer takes 10 hours to obtain the average water content of walnut seeds at the end of drying of 7.17% wet base. Drying rate of walnut seeds on drying time occurs the drying rate decreases with the estimation model of drying rate of time is y = 3.8532e-0.151x with correlation coefficient R² = 0.899 The drying constant obtained in each replication varies depending on water content and drying rate. Drying rate of walnut seeds on the water content of walnut seeds has a model of y = 0.3738e11.315x R² = 0.9722.
