This machine is used to chop leaves, twigs and branches into very small pieces, to avoid the bad smell due to the decay of organic waste and can be used as compost. The amount of cutting speed on the organic waste chopping machine with a chopping time of 2.5 kg of ketapang leaves is the average time obtained without fly wheels 2.0 minutes and with fly wheels 1.7 minutes, a time difference of 0.3 minutes. The chopping time of 2.5 kg of ketapang branches with an average time obtained without a fly wheel of 2.2 minutes and with a fly wheel of 2.0 minutes, a time difference of 0.2 minutes. The chopping time of teak branches is 2.5 kg with an average time obtained without a fly wheel of 2.6 minutes and with a fly wheel of 2.0 minutes, so the time difference is 0.6 minutes. So the cutting speed using a fly wheel is better. The results of the productivity obtained on the organic waste chopping machine, for the results of leaf chopping productivity without a fly wheel of 48% and those using a fly wheel of 58%, and the results of leaf chopping with a fly wheel are 10% more productive, for the productivity of chopping twigs without a fly wheel of 44% and those using a fly wheel of 49%, so the results of chopping twigs with a fly wheel are 5% more productive, and the results of chopping branches without a fly wheel of 37% and those using a fly wheel of 49%, so the results of chopping branches with a fly wheel are 12% more productive.

The Pelawan leaf chopper machine is an annual product of LPPM Universitas Brawijaya Malang and in collaboration with several universities, one of which is Bangka Belitung University which is focused on the Pelawan forest, Namang village, Central Bangka Regency. The chopping machine used has dimensions of 30 x 30 x 3 mm, and uses a 200-watt electric motor drive with a voltage of 220 V/150 Hz, with Rpm 2800 and 2 blades in the hopper. During the machine testing process, there were still deficiencies in the tool components which caused the results of the chopping to not be chopped properly. Therefore, it is necessary to identify existing problems and make design improvements to the pelawan leaf chopper machine to increase the capability of the chopping process. Identification was carried out on a pelawan leaf chopper machine in the Mechanical Engineering Laboratory at Bangka Belitung University. From the identification it is obtained; Firstly, the number of blades is 2, which causes the chopping process to not be optimal. Second, the distance between the hopper wall gaps is too wide, which affects the level of fineness of the chopped results. For this reason, design improvements were carried out to provide several alternative concepts (sketches) for the number of blades from various constructions on the machine. The alternatives given are 3 concept variants, the first is a 90° tilt propeller concept variant, the second is a 45° tilt screw layout concept variant and the third is a straight concept variant and a 90° tilt layout. In this research, variations of the concept following the assessment criteria and a distance between the blades of 45° enabled maximum results to be obtained.

Full textAbstract:
Conventional straw-returning machines were incompatible with ridge cultivation terrain and unevenly distributed materials, resulting in substandard operations such as insufficient leaf fragmentation, damage to ratoon stumps, and high cutting energy consumption. In this regard, this paper proposes a novel profiling configuration of chopping and returning machine to adapt to the coverage characteristics of cane leaves in furrow-ridge terrain. The leaves piled at furrow sole are intensively collected and fed into the whirling space by the flexible hook teeth assembly, and are cooperatively broken by the unequal-length swing blades densely arranged along the double helix. Based on the measured topographic trends and dynamic analysis of the leaf-shredding process, experimental factors affecting profiling cutting and picking capabilities of the main components were determined. Further, using chopping qualification rate (CQR) and fragmentation degree (CFD) as indicators, field trails were conducted through a response surface method to test the comprehensive crushing performance of the machine. After multi-objective optimization, the optimal structural and operating parameters were determined as: blade length gradient of 1.57 cm, teeth spacing of 6.84 cm and feed speed of 3.2 km/h. With such adaptive configurations, CQR and CFD reached 81.14% and 0.101, respectively, which were significantly improved by 60.50% and 47.99% compared to those of conventional machines. Crushed leaves appeared to be more thoroughly mixed with the soil and more evenly spread in the field. Meanwhile, the traction resistance tended to be stable, with an effective RSM 45.85% lower than the value of higher-level blade gradient, indicating a better overall fit with the irregular terrain. This study can provide a reference for the development of leaf-chopping and returning machines suitable for ridge-type crops.

Full textAbstract:
Processing leaves to make compost is generally still done by chopping using a machete, or many are not chopped, making it difficult for the leaves to decompose or rot. This research aims to determine the results of chopping using a single blade and by varying the size of the blade and varying the rotation speed of the machine. The benefit of this research is to determine the influence of leaf chopper machine components, especially the number of leaf chopper blades, using descriptive qualitative research methods with data collection methods, literature studies and observations. The research location is in the HKBP Nommensen University Laboratory workshop, Pematang Siantar, North Sumatra. The research process took the form of testing carried out in several stages, namely using a single blade by varying the length of the blade and varying the rotation speed of the machine to compare the speed and chopping results. Three trials were carried out each with varying blade lengths of 30cm, 35cm and 40cm and rotation variations of 2500rpm, 3000rpm and 5000rpm. The results are in the form of a comparison of speed and counting results between variations of 30cm, 35cm and 40cm. The test results more effectively lead to variations in blade size of 40cm. And the results of testing the engine rotation speed which is more effective leads to a rotation speed variation of 5000rpm.

<em>The P</em><em>e</em><em>lawan tree has many benefits in the community, one of which is its leaves for making herbal teas. The process of making this tea uses a chopper machine. This machine has existed before, but the dimensions of the previous were too large, which is where the initial purpose of making the machine was to help the community MSMEs whose users were women/mothers. Besides, the results of the chopping were still rough. Therefore, the design of the machine was carried out by changing the dimensions to 370 mm x 350 mm x 530 mm with an electric motor of 0.34 Hp with a motor rotation of 1325 rpm. There are four variations of blades angle, namely 10˚, 15˚, 20˚, and a combination of the angle. The goal is to increase the fineness of the chop. The results showed that with 10˚ produces 45.3% smooth and 54.7% rough, for 15˚ produces 37.31% fine and 62.69% rough, for 20˚ produces 36.24% fine and 63.76% rough, for the combined corners produces 38.58% smooth and 61.42% rough. The maximum production capacity of this machine is at an angle of 10˚ of 0.78 kg/hour</em><em>.</em>

Tobacco leaf chopping still uses the traditional method which is assisted by a motor that drives the blade to rotate, but the speed that cannot be adjusted. Therefore, an automatic tobacco chopper based on PLC and SCADA was created. This machine uses a blade that is driven by a 3 phase 0.5 PK AC motor which can be controlled manually using VSD and automatically using PLC and is also capable of monitoring and controlling using SCADA. In this chopping process using tobacco leaves that are still wet. This machine is equipped with an inverter whose acceleration can be adjusted so that the starting of the motor can be done in a soft start and braking can work optimally and efficiently. The results within one hour using a frequency setting between 15 to 35 Hz, a maximum of 116 kg of chopped tobacco leaves is produced with a thickness of 1 to 2 mm. The higher the frequency setting, the higher the RPM value where this RPM will determine the total capacity of the chopped tobacco

The design of the wilted tea stalk and leaf separation system aims to improve the quality of the tea produced especially by separating the tea leaves and stalks at the beginning of the process. Stages that are needed to be done include designing a chopper machine that is capable of chopping tea stems and leaves to a certain size and designing stem and leaf separation system with the pneumatic principle with suction. In this study, physical, mechanical and aerodynamic characteristics of tea leaves were measured. The result showed that force to release a leaf is in the range of values between 12.24-16.17 N smaller than the need for the cutting force of the stem and leaves and the greatest difference in force is achieved at a water content between 55 and 58% bb (leaves) and 66-68% bb (stalk). The leaf terminal velocity is <3 m s-1 while the tea terminal velocity is > 9 m s-1. Tea leaf yield value is very important as a reference in testing the performance of tea and tea leaf separator machines where the average leaf yield is 77.33% and the average stem yield is 22.67%. Keywords: characteristic of tea leaves, engineering, separation of tea leaves, withering of tea leaves

The physical and mechanical properties of sugarcane leaves were necessary for the design consideration of the relating storage, handling and processing equipment. The sugarcane trash at moisture contents of 23.40 and 73.91 % w.b. were used for this study. The mean length and unit weight of sugarcane trashes were 168.63 cm and 65.87 grams respectively. The average number of leaf of each sample was 4. The mean diameter of the thrash top, width and thickness increased with the increase of moisture from 23.40 and 73.91 % w.b.. The average leaf angles (β) relative to the horizontal plane of the first left leaf, second left leaf, first right leaf and second right leaf were 65.10, 73.36, 71.07 and 78.26 degrees for 73.91 % w.b., and 66.33, 73.50, 67.50 and 75.83 degrees for 23.40 % w.b. respectively. When the moisture content increased from 23.40 to 73.91% w.b., the static coefficient of friction increased from 0.30 to 0.43, 0.38 to 0.41, 0.30 to 0.37 and 0.54 to 0.66 for plywood, mild steel, galvanized iron and rubber plate respectively. The least static coefficient of friction occurred on the galvanized iron plate. The results from experimenting on mechanical properties showed that the maximum shearing force increased with the increase in moisture content from 23.40 to 73.91% w.b. respectively. The maximum shearing force was 360.15 and 457.32 N for moisture contents of 23.40 and 73.91% w.b.. The maximum tensile force decreased toward upper region of the leaf for both 23.40 and 73.91% w.b.. The results of this study would be useful for the design and optimization of the equipment associated with harvesting, threshing, chopping and processing.

A grass chopper is a machine used to chop grass and soft stems. In the grass chopping process, a sharp blade is required. The current problem is the blade get wear due to repeated sharpening of the blade, resulting in a non-uniform texture of chopped grass and often found some large grass sizes. Therefore, this research focuses on blade material engineering. This research was conducted by carburizing at 700°C for 60 minutes and adding carbon from coconut shell charcoal followed by quenching using water cooling media. The blade was made from a leaf spring made of JIS-SUP 9 steel. The results showed 106% of enhancement in carbon composition after the blade was treated by carburizing. This carbon composition enhancement affects the performance of the blade, namely higher hardness as shown by a 175% increase in hardness value and a 96.4% lower wear rate than the untreated blade.

With the use of current technologies of preparation of pressed forage, the losses of valued leaf part of grass plants come up to 14%, which is equivalent to significant losses of total weight of harvested hay. From this perspective, the purpose of the research is to develop a resource-saving technology of preparation of high-quality chopped hay, and to design a pick-up chopper for its implementation. To substantiate the offered technology, the method of system analysis is applied; to develop the structural and technological scheme of universal pick-up chopper, the method of design of agricultural machinery is used. As a result of theoretical researches, the analytical expression is obtained for determination of total yield losses, that are equivalent to the losses of leaf part of forage. The expression is proposed as a new optimization criterion for substantiation of different technologies of forage preparation. To improve the quality of forage and to exclude operations leading to the losses of leaf part of grass plants, a technology of preparation of chopped hay is proposed. Hammer and knife working bodies of a pick-up chopper provide high-quality chopping of dry and wet forage. The machine is equipped with new pick-up mechanism without treadmill, rollers, cranks or bearings for reliable hay picking up. The results of experimental researches allow to determine the following optimal parameters of the machine: the air flow speed in deflector 15 m/s; the rotation speed of pick-up reel 60 rpm; the optimal productivity 8-9 t/h; the losses of chopped forage 1.83%. The performance tests of a pick-up chopper equipped with hammer mill and new pick-up mechanism showed that it provides the preparation of high-quality chopped hay with reduction of operating costs by 2 times as compared to the roll technology of forage preparation.
