Sesame is one of commodities highly potential to support a variety of industries and promising for export. To respond this, it is deemed essential to analyse and construct any forms of sesame processing technology. An appropriate technology that is highly needed by farmers or community of small-scale industry for the management of post-sesame harvest is sesame peeling machine. The objectives of this research are to (1) develop a model of mechanism for sesame peeling machine using wet system that can accomplish the post-harvest of sesame peeling at capacity above 120 kg/hour, and (2) to observe the performance of sesame peeling machineusing wet system. The research method was conducted through the ways of (1) exploratory study on the small-scale industry/sesame-based farming in relation to the sesame peeling system, (2) data analysis on the result of exploratory study, (3) design and construction of the sesame peeling machine, (4) test on the performance of sesame peeling machine to observe the product capacity of sesame peeling (kg/hour) in terms of more intact quality by combining some variables consisting of (a) electrical power required (watt), (b) optimal axis rotation (rpm), (c) water flow rate required in peeling (litre/minute) to make the production from the peeling undamaged and (d) clearance (mm). From the test result on the performance, it was observed that the most optimal combination of variable treatment that is able to enhance the capacity and the quality of the peeling results was obtained in the water flow rate (Q) at 2.5 litres/minute, the clearance regulation (C) at 2.5 mm, the axis rotation of sesame machine (n) at 560 rpm, and electrical power (P) at 1 PK (740 watts). From such treatment combination, the capacity 140 kg/hour with 95% of intact peeled production (the level of damage under 10%) was obtained. © Research India Publications.
