    Design And Implementation Of A Remote Controlled Water Waste Collector With Fish Feeder
    (Department of Electrical and Electronic Engineering, 2021-12) AKTER, AYESHA; JARIN, SHALAHA AKTER
    The operation was done in response to the existing state of our national rivers, which are clogged with sewage and polluted with poisonous materials, garbage, and other contaminants. The Bangladeshi government has assumed care of river cleaning and has invested a significant amount of money in projects such as "Karnafuli," "Halda," and several big and minor projects in places such as Chittagong. This equipment was created with this in mind to clean the surface of the river water. Almost every industrial process has been atomized these days in order to provide products more quickly. In large production, automation is extremely important. We built a remote-operated, solar powered river garbage gathering equipment for this project. The project's major goal is to minimize the amount of men and time spent cleaning the river. With the aid of three motors with chain/belt conveyor drive arrangements, we were able to automate the operation of river cleaning in this project. The following are some automation requirements. The cleaning or trash collecting equipment is controlled via an RF transmitter and receiver. Computers, hydraulics, pneumatics, robots, and other forms of automation may all be used, but pneumatics is a particularly appealing medium for low cost automation

    INTENSITY OF INFESTATION AND MANAGEMENT OF BRINJAL SHOOT AND FRUIT BORER (Leucinodes orbonalis Guenee) IN KHARIF SEASON
    (DEPT. OF ENTOMOLOGY, 2006-06) AKTER, AYESHA
    An experiment was conducted at the Sher-e-Bangla Agricultural University (SAU), Dhaka, during January to July, 2005 to observe the infestation level and to evaluate the effectiveness of different management practices against brinjal shoot &fruit borer, Luc inodes orbonalis Guenee Seven treatments comprising mechanical & cultural control with different combinations of three promising insecticides eg, Sumialpha 5EC, Suntap 50WP and Furdan 5G were tested on a local brinjal variety “Khat khatia” laid out in RCBD with 3 replications Highest infestation of shoot (17%) & fruit (63% by wt & 75% by no ) was observed in the control plot, which was significantly highest from all other treatments. Treatment 6 consisting of mechanical & cultural control + Suntap 50WP @ 1 g/1 & Sumialpha 5EC @ I ml/1 of water at 5% infestation level gave the best performance resulting significantly lowest shoot (6%) & fruit (25%) infestation confirming highest yield (20 96 ton/ha). Treatment 3 -Furadan 5G @ 1.5 kg ai/ha single application + Sumialpha 5EC @ lml/1 of water at 7 days intervals also gave statistically similar results. The intensity of fruit infestation by BSFB was higher at later stages of crop growth for all the treatments
