Production Efficiency of Corn Shellers in Sidomulyo Village, Kutai Kartanegara, East Kalimantan

Corn farming communities in the Anggana sub-district usually harvest dry corn every 2-3 months, where the harvested dry corn is 45 mm in diameter with a corn weevil diameter of around 3.3 mm. The production of dry corn produced reaches 200-700 kg per harvest. According to the head of the joint farmer group (GAPOKTAN) Kutai Lama Village, Anggana District, in addition to corn ore, the weevil can also be used as a medium for making mushrooms named by the jenggel mushroom farmer group (weevil mushroom), after the jenggel mushroom is harvested, the corn weevil still functions for worm media. Worms are used to feed the livestock of birds, fish, giant prawns, chickens, goats and cows. Livestock waste is used as organic fertilizer in corn plants. Corn is harvested and so on. The problem is that the corn sheller machine that the farmer group uses so far produces corn weevils that are cut or crushed, so they cannot be used as a medium for making jenggel mushrooms and worm media. Finally, to meet the needs of jenggel mushroom making media and worm media, the farmer group chose to use a manual, namely picking by hand. Shelling corn by hand in addition to not being produced also makes the palms thicken because they rub against the surface of the corn kernels. Previously, the Corn Sheller Machine in the Independent Farmer Youth Group of Kutai Lama Village, Anggana District, Samarinda, East Kalimantan was very well received, because according to the chairman of the combined farmer group (GAPOKTAN) together with the deputy chairman of the Independent Farmer Youth of Kutai Lama Village, Anggana District, Samarinda, East Kalimantan said that the results of the shelling process were in accordance with what the farmer group wanted where the corn cheeks were clean and the corn weevils were intact so that can be used as a medium for making jenggel mushrooms and worm media. To see the level of efficiency, it is necessary to calculate the level of efficiency when compared with similar machines sold on the market. With the calculation of the efficiency level, it can be concluded that with the 1 HP machine made, the corn threshing machine has an efficiency level of 1400 and includes a very high level of efficiency
