A Study on Determination of Optimum Partial Gear Ratios of Bevel Helical Gearboxes

Paper ID- AMA-06-11-2021-10829

This paper introduces a study on the optimal design of a two-stage bevel helical gearboxe. The objective of the study is to determine the optimal partial gear ratios of the gearbox to achieve the minimum gearbox bottom area. To do that, a simulation experiment was conducted. From the results of the experiment, the influence of main design parameters including the total gearbox ratio, the face width coefficient of bevel gear, the face width coefficient of helical gear, the allowable contact stress of the first and the second stages, and the soutput torque on the optimal gear ratios was investigated. In addition, a regression formula for calculating the optimal gear ratio for the second stage has been proposed.

Ecofriendly Approach to Improve Drapability and Process Optimization of Aminosilicone Treatment on Jute Fabric

Paper ID- AMA-02-11-2021-10825

The current research work sets the radar towards the finishing of jute fabric by application of aminosilicone softener by pad-dry-cure method, which was set after optimization of concentration, pH, material to liquor ratio, treatment temperature and time, drying temperature and time & curing temperature and time. The impregnation of the finish into the jute fabric resulted decrease in bending length, flexural rigidity and drape coefficient, thus causing improvement in softness and drapability of jute fabric. The finish also had a positive impact in controlling the colony forming units of Gram +ve bacteria (Staphylococcus aureus) and Gram -ve bacteria (Escherichia coli). There was no comparable difference in ultra-violet protection property of the treated jute fabric. The surface morphology was studied by scanning electron microscopy. This finish is of extreme importance because it not only improves the drawbacks of jute fabric but also it is environmentally benign and non-toxic.

Development of a Planning and Mission Supervision System for a Ground Agricultural Mobile Robot

Paper ID- AMA-02-11-2021-10824

A series of algorithms was implemented to plan optimal routes and generate smooth trajectories, for optimal and safe navigation of an agricultural robot. For the generation of optimal routes, the algorithm called A* was implemented, while for the smoothing of the trajectory the algorithm called Bezier curves was utilized. The system is capable of generating smooth trajectories with a resolution of up to one centimeter, in less than a second, performing by teleoperation the monitoring and remote control of the robot with frequencies of 2 Hz, which makes it suitable for robots in agricultural tasks. The developed software permits demarcating, from an aerial image, the crop rows or other obstacles present, and once the optimal route is generated to visualize its smoothing and geo-referencing, to provide a sequence of geographic coordinates, through which the robot must navigate.

Development of Battery Operated Row Crop Weeder for Small Farm Mechanization

Paper ID- AMA-01-11-2021-10822

The manual method of weed control is effective, but the scarcity of labour during the peak season and delay in weeding operations ultimately reduces crop yield. The use of chemical herbicides over a period of time leads to environmental pollution. Mechanical weeding is preferred over chemical use because herbicides are expensive and hazardous to the environment. Therefore, the development of mechanical weeder is imperative to meet the demand of small-farm mechanization. The available engine-operated mechanical weeder increase drudgery to the operator due to exposure to high levels of vibration. Hence, the complexity of these situations has resulted in switching over to an electric- drive mechanical weeding system to increase the productivity of the man-machine system. Therefore, a battery-operated inter-row weeder has been developed. It has an electro-mechanical approach such as the application of a DC motor as a power source and a combination of weeding mechanisms to complete the operation with less drudgery and higher efficiency. The field experiments were conducted in soybean crops under sandy-loam soil conditions. The field performance of weeder for V- type blade and straight blade tool were evaluated at the forward speed of 2-3 km/h. The results showed that the average weeding efficiency, field capacity, field efficiency, percentage plant damage, and performance index of the machine for V-type blade were found to be 91.42%, %, 0.051 ha/h, 90.73%, 2.37% and 2496.30, whereas for straight blade 86.78%, 0.048 ha/h, 88.50%, 3.55%, and 1497.04 respectively. The average power consumption of the weeder for V-type blade and the straight blade was found 185.6 and 262.5 W. The average draft force 269 and 391 N was observed for V-type and straight blades. The performance of the V-blade was found better over the straight blade. The developed weeder was found suitable for small-farm mechanization.

The Use of Organic Fertilizers and Arbuscular Mycorrhizal Fungi to Increase the Growth of Banana Raja Bulu Seedlings (Musa paradisiaca L. cv. Sapientum)

Paper ID- AMA-31-10-2021-10820

Bananas are commodities that are easily cultivated and developed in Indonesia. Optimizing plant growth is carried out through organic fertilizer and Arbuscular Mycorrhizal Fungi (AMF). This research aims to get the right type of organic fertilizer and AMF and understand whether there is an interaction between organic fertilizer and AMF dose to increase the growth of the banana plant Raja Bulu of tissue culture. The research was located in the experimental field of the Faculty of Agriculture, University of Sebelas Maret, Karanganyar. The research design used was a factorial, completely randomized design with a combination of 2 factors. The first factor is the type of organic fertilizers goat manure, cow manure, vermicompost, and compost. The second factor is the dose of AMF 0 g, 5 g, 10 g, and 15 g. The data obtained were tested statistically by statistical analysis with ANCOVA based on the F test level of 5%. If it had a real effect, further tests were carried out using DMRT with a 5% level. The variables observed were plant height, number of leaves, leaf width, leaf length, mycorrhizal infection, and stem diameter. Results showed an interaction between the types of organic fertilizer and the doses of AMF against the diameter of the stem of the plant of banana Raja Bulu. Goat manure can increase the growth of banana Raja Bulu better than the treatment of compost fertilizer. AMF dosage treatment of 5 g to 15 g per plant has not increased the growth of the banana Raja Bulu.
