Abstract

The development of coconut processing technology to produce coconut milk for small and medium industry until now still uses a separate processing machine between coconut grating and coconut squeezing, so it is considered ineffective and less efficient. Therefore, previous studies aimed at improving the performance of coconut processing machines into coconut milk, have been carried out with the design of coconut milk producing machines that are integrated between the coconut grating process and the coconut milk squeezing process utilizing centrifugal force. Research aims to manufacture, a functional test of the machine components, and a calculation of the production cost per unit of the machine. The results showed that the coconut milk production machine has a power of 0.75 Kw, a maximum shaft rotation of 2850 rpm and an engine dimension of 600 x 600 x 1200 mm. The capacity of coconut milk production machines is 10 liters per hour, visual test results show that coconut milk production machines can function well at 1000 rpm, 1500 rpm, 2000 rpm and 2500 rpm. The total production cost for a unit of centrifugal coconut milk production machine with a production capacity of 10 liters per hour is Rp. 4,760,000.

Abstract

This research aims to identify the causes of the failure of the fastening bolts for the trunnion plate on cement mill unit 1 at PT. X. The research method used is an empirical study consisting of two main phases. The first phase involves identifying the causes of bolt fractures through macroscopic observations to examine the patterns of bolt fractures. The second phase involves analyzing the forces acting on the bolts by calculating the inertial forces generated due to torque tightening, followed by determining the centrifugal forces produced by the ground material and calculating the bending moments affecting the bolts. The results of this research revealed that the main cause of bolt failure is the presence of crack patterns characterized by significant plastic deformation in the bolt body; this type of fracture is categorized as ductile fracture. Analysis of the forces acting on the bolt also revealed that the stress applied to the bolt exceeds its strength capacity. The stress reached 436 MPa, whereas the bolt's strength was only around 330 MPa (yield strength). The findings of this research are expected to serve as initial data for further research that will investigate the metallurgical aspects as a deeper cause of bolt failure.

Abstract

The finned drive wheel technology is widely used for wet rice fields. Currently, finned drive wheels for peat fields have not been developed and still use traditional agricultural tools such as hoes and sickles, while the finned drive wheels for wet rice fields are not yet able to work optimally on peat rice fields. The driving wheel model and testing in peat rice fields were carried out in this research. Design and manufacturing were carried out by referring to previous research literature. This initial research was carried out in wet rice fields on open-close finned drive wheels and standard finned wheels, with the aim of measuring the comparative level of performance of the two wheel models. The wheel performance measured is sinkage and wheel rotational speed. The research produced two models of driving wheels, namely the standard fin type with a driving wheel diameter of 35 cm and a number of 8 fins and the open-close fin type producing a driving wheel diameter of 40 cm with 4 arcuate fins on the top surface of the driving wheel. Standard fin type drive wheels have smaller sinkage (11% on average) compared to open-close fin type wheels. The finned drive wheel with the open-close type has an average speed level that is 27.7% higher when compared to the standard finned type.Keywords – wheel drive, standard fins, open-close fins, sinkage, wheel speed

Abstract

Agricultural technology to support the agricultural sector, especially peaty paddy fields, should be developed, because peat land with a thickness of less than one meter has been recommended for rice crops. supported by a potential peatland area of ​​up to 21 million Ha or 10.8% of Indonesia's land area. Currently, peatland farming communities use sickles to harvest rice and hoes to cultivate the land. So far, hand tractor finned wheel drive technology has been widely used for cultivating wet paddy fields, whereas in conditions of peaty paddy fields it has not been able to be used because of the high level of sinkage and wheel slip, for this reason a new model of wheel is needed that is capable of working in peaty paddy fields. The aim of the research is firstly to find the right model of driving wheel for use in peaty paddy fields, secondly a prototype driving wheel for peaty paddy fields, and thirdly to experimentally test the driving wheel. Research results (1) prototype with a driving wheel diameter of 35 cm and the number of fins is 8 for the standard fin type and for the double fin type the driving wheel diameter is 40 cm with 4 vertical arc fins, which are placed on the surface of the driving wheel. (2) Comparison with the same type of loading shows that the double fin type drive wheel has a relatively smaller level of wheel loading (around 20%) when compared to the standard type drive wheel. (3) The sinkage level of the standard type drive wheel has a smaller sinkage (around 10%) compared to the double finned wheel type, in tests with the same type of loading. test loads for wheels are 20 kg, 40 kg and 60 kg. The double fin type drive wheel is good for use in peaty paddy fields.
