Abstract

The salt washing unit is part of the salt processing machine. This unit's function is to wash raw salt with brine. This unit has a motor, agitator blade, washing chamber, and frame. The frame structure strength of the salt washing unit needs to be evaluated to ensure safety. This research aims to design the salt washing unit and obtain simulation results of frame structure strength to ensure the safety of the salt washing unit. This research was carried out by simulation to look for stress, strain, and changes in the shape of objects (displacement). The frame strength simulation was carried out using Solidwork software. The salt washing unit with a 50 kg/hour capacity has been designed. It has a cylindrical shape with 990 mm in height and 680 mm in diameter. From the simulation results of strain, it can be concluded that the minimum point is 1.80 × 108 Mpa, and the maximum point is 1.63 × 105 Mpa. From the simulation results of displacement, it can be concluded that the minimum point is 0 mm and the maximum point is 2,296 mm. The maximum stress is 5.254×106 N/m2, and the minimum stress point is 1.803×106 N/m2.

Abstract

Agriculture tools necessary for increasing food security in Indonesia. An automatic spraying for plant became one of the tool that help in pot plant maintenance. This study was developing a prototype of automatic line follower robot for spraying plant. Designing a new construction and adding a line follower sensor, this robot could move between plant pots with guidance of black line. Main chassis of this robot made from 3 mm aluminum plate with 50 cm length and 20 cm width. Control of this robot using Arduino Uno as microcontroller that could control the movement of the robot and also could control movement of nozzle and flow rate. Performance testing of this robot held inside the room with concrete floor and placed on the white fabric with black line as a guidance and sign to stop and spray. As the result, average linier speed for this robot was 0,7 m/s and flow rate for spraying was 8,9 ml/s with 89,5% accuracy.

Abstract

The raw salt should be reduced the size to convert it into consumption salt. Salt crushing machine generally was designed to reduce salt grain size using rollers for crushing. The small-capacity salt-crushing machine should be designed to meet the needs of small businesses. This study aims to design a salt-crushing machine in a small capacity with a proper power transmission system that will be applied to a roller-type salt crusher. The transmission system is designed to upgrade the performance of roller-type salt crushers through V-belt and pulley transmission mechanisms and obtain the appropriate size or type of V-belt and pulley based on the capacity of the drive motor. The results show power required to crush salt by this system is 299.46 W. The motor used is a single-phase AC motor that has a power size of 1/2 HP, and the corresponding v belt is type A with a size of 51 inches, the rpm needed is 360 rpm, and the distance between rollers is 0,7 mm. Then the pulley needed is with a ratio of 1: 4. The pulleys used are type A1 which has a diameter of 3 inches and 12 inches. The average salt weight loss after the crushing process was 14.27%.
