Abstract

Palm oil is an industrial/plantation plant that is useful as a producer of cooking oil, industrial oil and fuel. In the world, Indonesia is the largest country that produces palm oil. Most of the harvesters of fresh fruit bunches (FFB) and oil palm fronds still use manual methods with egrek and dodos harvesting tools. Using a manual egrek requires quite a lot of energy and a long time in the harvesting process, therefore a tool is needed that can reduce energy and time but the price is still affordable for oil palm farmers. The egrek pipe is a tool used to cut fronds and fresh fruit bunches. Iron pipe is a mixture of aluminum containing 4% copper. Pipes and pipes can be modified into cutters of fronds and fresh fruit bunches. Modification of the tool utilizes iron pipes, iron plates, iron sticks and pipes. The principle is done by moving the tool that is designed and made forward and backward.

Abstract

CNC machine is a machine tool whose entire operation is controlled using a computer by inputting N and G codes. There are 2 types of programming for CNC lathes, namely incremental (the starting point of the program can change or the program endpoint becomes the beginning point of the next program), absolute (the starting point becomes the fixed reference point of the program. The study aimed to determine the low surface roughness value of S45C carbon steel with feeding motion variations of 0.15 mm, 0.25 mm, and 0.35 mm with a cutting depth of 0.4 mm and a constant spindle rotation speed. The insert used is branded iscar with a radius of 0.8 mm.. The lowest roughness value at feeding motion of 0.15 mm belongs to the roughness class, namely N7. The intermediate roughness value at feeding motion of 0.25 mm belongs to the roughness class N7. While the highest roughness value in feeding motion (feeding) 0.35 mm is included in the roughness class, namely N8. The average value results are obtained from the testing process using a roughness test tool (stylus).. The effect of feeding motion on the results of the surface roughness of S45C carbon steel in the CNC process is that the smaller the feeding value, the lower the roughness value produced, while the greater the feeding value, the higher the roughness value produced.

Abstract

Threshing is the post-harvest handling stage after the harvesting process. Threshing is an integral part of the palm post-harvest handling process. The harvested oil palms are threshed to separate the fruit from the bunches. The threshing process is carried out so that small oil palm fruits or oil palm fruit bunches weighing below 5 kg can be accepted at the palm oil mill. Generally, the weight of fresh fruit bunches (FFB) under 5 kilograms is not sold, so before being taken to the palm oil mill, it must be threshed first so that the palm oil becomes brondolan or grains of palm oil that can be accepted by the palm oil mill. In this final project, the author designed a small oil palm fruit threshing machine from the bunches aimed at increasing the profits of farmers or oil palm entrepreneurs, because small oil palm fruits can be accepted at palm oil mills. In this design, the driving engine uses a fuel motor motor with a power of 7 HP.

Abstract

In the practical and sophisticated world of the manufacturing industry, the best product results are needed. To answer market needs that want products with maximum results and produce them in a short time, the non-conventional Computer Numerical Controlled Lathe (CNC) is available as a machine tool production tool that is controlled using a computer system to cut workpieces which are rotated to determine the roughness value on the workpiece surface. The aim of this research is to obtain the lowest surface roughness results. Using S45C carbon steel material with Sumitomo CNMG 120404-N-Gu-AC8025 brand insert with a Radius of 0.4 mm on the SKT 160A CNC Turning machine. The next process is the process of turning the workpiece with variations in cutting depth of 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm , 0.9mm, 1.0mm, 1.1mm. Using the G96 program code, the feed movement is 0.15 mm/rev with a constant spindle speed of 2700 rpm and using a Stylus as a measure of surface roughness value. By carrying out 1 test on 11 samples, each sample consisting of 3 test points. Based on the results of surface roughness data, the lowest average Ra roughness results for an insert radius of 0.4 mm were 1,115 µm at a cutting depth of 0.6 mm and was included in the roughness tolerance value N6.
