Abstract: This rice planter model is designed to make it easier for farmers to plant rice quickly, easily, and very effectively. This tool is designed not to use a motor or engine drive, this can save costs because it does not incur fuel consumption costs. This rice planter is made with a size that is not too large, so it is easy to use on narrow land, saves maintenance costs and is simple to use. This tool can be lifted by only 2 people or do not need to use heavy equipment. The design model and working principle of this rice planter uses a paddy hook and pusher to anchor rice seeds to the ground, equipped with a push lever that can be pushed easily, as well as a rice seed holder that moves to the left fully and then to the right (once the rotation) , each paddy planting lever is operated so that the rice seeds can be evenly attached to the hook, and the way this tool is operated is by pulling the frame lever with the left hand.....

Abstract: A hand tractor is a machine-powered agricultural implement that may be used for land/land processing. Tillage operations may be sped up and made easier with tractors. The hand tractors that are now on the market are usually too big to operate on terraced or narrow terrain, where there isn't enough flat land for rice fields. To combat this, farmers must be provided with instruments that are straightforward, inexpensive, and effective methods of working in accordance with their demands and the state of the rice fields, where there are still several processes. The axle will be directly coupled to the model of the teeth to shred the soil to be plowed instead of using wheels in this revolutionary hand tractor's design idea. The 2 HP gasoline engine that will power this hand tractor is envisioned.........

Abstract: The steel plate shear walls has various advantages like high stiffness, high ductility and energy dissipation. The objective of current research is to investigate the strength of SPSW using techniques of Finite Element Analysis (FEA). The design of SPSW is developed in creo design software and structural analysis of SPSW under lateral load conditions is conducted using ANSYS simulation package. The effect of circular opening on strength of SPSW is evaluated on the basis of stresses and deformation. The presence of opening in SPSW causes reduction in strength of SPSW. The incorporation of circular opening has led to an increase in equivalent stress and deformation of plate significantly. Therefore, while creating any opening on SPSW the reduction in strength of plate needs to be considered.

Abstract: It is necessary to evaluate the irrigation system to ensure that services are increasing, sustaining or even decreasing. Evaluation of irrigation services is very dependent on the condition of the buildings and irrigation canals that have been built. This study aims to obtain the index value of the irrigation area performance assessment so that the output is in the form of recommendations on buildings and irrigation canals in detail then the calculation of repair costs and maintenance and operational costs on the Jegong Irrigation Network in Suren Village, Ledokombo District, Jember Regency. With the help of the E-Paksi application and conducting field searches, it was......

Abstract: In the new world, nations developing rapidly for economic stability due to which higher growth is seen in urbanization, because of which noise pollution is increasing day by day causing one of a kind of stress to humans who are exposed to those areas. If these stresses are unattended or minimized the human mental health will get deteriorated due to which the productivity of humans in a given environment will affect. Noise control and its principle play a keen role in creating an acoustically pleasing environment. This is achieved by bringing down the sound pressure level which is not harmful to humans. In the experimental study the reduction of SPLs is seen in the presence......

Abstract: This research will be used as raw material for the manufacture of polymer membrane of Polyethersulfone (PES). Properties of a membrane are known about the characteristics of the membrane which can figure out the effectiveness and efficiency of a membrane that is created by the presence of parameter testing. Study of the parameters used, namely tensile strength, microstructure, and permeability of the membrane. This membrane is created using three different aqueous concentrations of Polyethersulfone (PES) (20%, 22.5%, 25% by weight) with the addition of concentrations......
