Abstract

Erratic climate change and limited drying space in apartments lead to an inefficient clothes drying process. Commercial clothes dryers are often sub-optimal in terms of drying duration and energy efficiency. Clothes dryer technology without dependence on solar energy has been widely circulated, but has disadvantages, such as long drying time and high price. This research develops a temperature control system on a prototype rotary-type clothes dryer to optimize drying time. The dimensions of the prototype are 0.65 cm x 0.70 cm x 90 cm, the power consumption of the cloth dryer is 598.4 watts, using a DHT22 sensor to control the temperature. The motor speed rotates at 730-790 rpm, with the fan rotating constantly, and the heater has temperature set points of 43°C (upper) and 45°C (lower). The system applies an on-off control method to achieve the desired temperature set point. The test results show that the temperature control system in the clothes dryer with the on-off method is successful with an error rate of 0.74% for a mass of 1 kg of clothes. This error rate meets the set standard of no more than 5%, indicating that the on-off control system works as expected.

Abstract

In the industrial world, friction between machine elements such as bearings can affect the performance and service life of components, making lubrication systems based on tribology principles very important. This study analyzes the selection of lubricants for SKF BT2-8131 A roller bearings in a Vertical Roller Mill owned by PT. Solusi Bangun Indonesia, Tuban Factory, with the aim of determining a better lubricant than before and identifying the type of lubricant film formed. The research process involved collecting machine operational data and lubricant specifications, as well as calculating the kappa value and Streibeck curve to determine the type of lubricant layer, such as boundary, mixed, or full film lubrication. The results showed that Pertamina Masri RG 460 lubricant with a kappa value of 1.29 was selected because it had adequate technical performance and was more economical, although Mobil SHC 600 460 lubricant with a kappa value of 1.73 was also recommended if technical performance was the main priority. The results were validated by calculating the predicted bearing life to ensure optimal efficiency and performance.

Abstract

A chain grate boiler is a type of boiler with a moving grate system to transport solid fuel through the furnace. The coal gate regulates the distribution flow of coal from the hopper to the furnace. In the 20 tons/hour capacity chain grate boiler at PT Sopanusa, the existing coal gate experienced mechanical failure due to damage to components in the roller chain, shaft, and bearings, so that it could not operate as a coal distribution regulator. To overcome this problem, it is necessary to redesign the coal gate on the 20 tons/hour capacity boiler chain grate hopper at PT Sopanusa. The main components, such as the chain, sprocket, worm gear, shaft, bearing, and pin on the coal gate, need to be redesigned to avoid mechanical failure of the coal gate. After redesigning the main components of the coal gate, a coal gate design that is compatible with the boiler chain grate construction will be obtained. The results of the coal gate redesign are as follows: a lifting chain with Chain Grade 80 type, 4 mm diameter, and a sprocket diameter of 320.92 mm; a worm gear with a ratio of 30:1 using hardened steel for the worm and phosphor bronze for the gear; a shaft with S45C material, 60 mm diameter; bearings using single row deep groove ball bearings, unit number ASB Bearing UCP 212; and pins made of SAE 1045 material with dimensions of 60x20x12 mm to support the manual coal gate mechanism on the 20 tons/hour capacity boiler chain grate at PT Sopanusa.

Abstract

Lombok has high tourism potential that requires a reliable electricity supply, one of which comes from the Lombok FTP-2 2Å~50 MW Power Plant in Sambelia, East Lombok. This power plant uses coal supplied through a Coal Handling system, with Belt Conveyor BC-7 as one of its main components. This study aims to redesign the BC-7 Belt Conveyor with a capacity of 150 TPH through manual calculations of capacity and motor power and using Helix Delta T-6 Conveyor Design software. The study focuses on one conveyor unit, using coal material, and only discusses aspects of capacity and motor power under stable operating conditions. The methods used include literature studies, field observations, and data collection from the Lombok FTP-2 PLTU. The data was then processed for manual calculations and software simulations. The results showed a transport capacity of 165 tons/hour (a 10% increase from the previous capacity). The highest motor power without SF from the software was 8.49 kW (19.75% greater than the manual result). The use of software proved to be more efficient and helpful in planning belt conveyor systems.

Abstract

The impeller is a crucial component of a centrifugal pump, as it converts shaft power into fluid energy. There are three main types of impellers: closed, semi-open, and open, each with distinct characteristics when handling different working fluids. Fluid viscosity can significantly affect pump performance. Closed impellers are particularly effective for pumping water; however, their performance decreases when handling high-viscosity fluids. Modifications to closed impellers can be implemented to address this decline in performance. In contrast, semi-open impellers are better suited for managing highviscosity fluids than closed impellers. Both experimental and numerical methods were used in this study. Measurements of performance were acquired through the construction of a pump testing facility. Modifications and variations in the shape of the impeller were created using 3D printing techniques with polylactic acid (PLA) as the material. In addition, the experimental results are strengthened by pressure contour analysis in numerical simulations. When pumping molasses at 65 lpm, the highest performance was achieved with a closed impeller, which attained a head of 7,9 m, an efficiency of 17.8%. Conversely, a 6-blade semi-open impeller, achieving a head of 12,2 m, an efficiency of 29%. So, this modification can improve the Head by 54,4 % and the efficiency by 63%.

Abstract

The Rice planting process by “Kelompok Tani” in the Tulungagung, East Java is done manually, Manual planting requires a lot of manpower and very costly because the Landowner need to pay to the laborers to plant their Rice Paddy yet requires a lot of time to do the work until done completely and drains a lot of works and efforts. From that, the Rice planter is designed to reduce the planting process. The design concept adopted the “Jajar Legowo” Rice Planting method, with the distance arrangement applied from the Gears comparison so as to produce equal and uniform distances. This manpowered machine is expected to help The Farmers to shorten the planting process without incurring additional costs for Fuel. From the results of the planning and calculation produced a machine with capability of planting rice 26.4m2/ hour using number 40 of chain, sprocket size 242.80mm and Ratio of each sprockets are 1: 4 to produce a uniform planting. Using a 400mm long shaft for the planter and 10mm diameter with ST37 material. On wheels use Bearing with 30mm Bore.
