Abstract

This study focuses on the design and development of a smoking device aimed at enhancing the quality and production efficiency of smoked fish. The primary objective was to create a device that optimizes the smoking process, ensuring consistent product quality while increasing production capacity. The development process involved a systematic design approach, including the selection of materials and construction techniques. The smoking process utilized a combination of drying and the application of natural smoke compounds derived from the combustion of organic materials. Performance testing was conducted using catfish as the primary substrate, with measurements taken for smoking duration, moisture content, and production rate. The effectiveness of the device was evaluated based on sensory characteristics, including texture, color, and aroma. The smoking apparatus was constructed with dimensions of 126 cm x 100 cm x 180 cm and is capable of accommodating up to 32 kg of fresh fish per smoking cycle. Results indicated that the smoking device achieves a production rate of 4 kg of smoked fish per hour, yielding products with a desirable golden-brown color and distinct smoky aroma. The findings demonstrate that the device significantly improves production capacity and allows for enhanced control over smoking conditions, contributing to greater consistency in product quality.

Abstract

The main problem faced by local farmers and fruit vendors is the lack of efficient and energy-saving storage facilities, causing fruits to often experience quality degradation and spoilage. This study aims to design and test a prototype of solar-powered cold storage with a thermoelectric cooling system (TEC) as an energy-efficient and environmentally friendly storage solution. The prototype uses a 100-watt solar panel as the primary energy source, combined with a Peltier TEC1 module to generate cooling. The test results show that the system can lower the internal temperature to 12°C within 3 hours. The system also achieves an energy efficiency of 18.07%, which is considered sufficient for small-scale thermoelectric applications. The use of solar energy enables the system to operate independently without relying on conventional electricity, offering an energy-saving and environmentally friendly solution. This prototype is deemed suitable for application in tropical regions, such as Indonesia, which has abundant solar energy potential throughout the year. This technology is expected to be a practical solution for farmers and small-scale vendors to reduce post-harvest losses while supporting carbon emission reduction efforts in the agricultural sector.

Abstract

Sustainable water-based food production systems are essential to meet the growing demand for food while preserving water resources and ecosystems. These systems should integrate practices that manage water efficiently, such as green water management. Such practices conserve water and ensure the production of nutritious food, contributing to food and water security. The correlation between these systems and the production of wave breakers moulds to produce plastic waste bricks lies in the shared goal of environmental sustainability. Plastic waste bricks, created by repurposing plastic waste into durable building materials, offer a solution to plastic pollution. These bricks can be used to construct wave breakers, which protect shorelines and prevent erosion. This project aimed to fabricate a 3D-printed wave breaker mould for sustainable plastic bricks. Experimental testing was carried out to investigate this mould’s feasibility. It has been deduced that using 3D-printed moulds for wave breakers can lead to innovations in coastal engineering, potentially improving the efficiency and effectiveness of wave energy dissipation and offering economic and environmental benefits. It is recommended that surface modification could be an alternative to improve the mould’s wear and friction impact.

Abstract

This study is focussed on the performance of a solar hybrid recirculating mixed-flow dryer (SHRMFD) for drying paddy with different drying air temperatures. The drying experiments were carried out at average air temperatures of 50 °C, 60 °C and 70 °C. The SHRMFD reduced the mass of paddy from 420 kg (16.90% wb) to 406.07 kg (14.17% wb) in 360 min; from 420 kg (16.80 % wb) to 407.63 kg (14.17%) in 165.4 min; from 420 kg (16.75 % wb) to 407.35 kg (14.17% wb) in 143.3 min for average air temperatures of 50°C, 60°C and 70°C, respectively. The highest drying rate (3,324 kg/hour) was achieved at an average air temperature of 70°C. The specific moisture evaporation rate (0.171kg/kWh) and thermal efficiency of SHRMFD (25.04%) were achieved highest at an average air temperature of 50°C. The lowest specific energy consumption (11.804 kWh/kg) was achieved at an average air temperature of 50°C. The energy contributed by the biomass furnace and the solar collector for SHRMFD were 13.28 and 14.74%; 8.08 and 17.50%; and 6.10 and 20.35 for average air temperatures of 50°C, 60°C and 70°C, respectively. The SHRMFD performance is better at an average air temperature of 50°C because it has higher thermal efficiency and lower energy consumption.

Abstract

Cafes have become a favorite place for various groups by providing a variety of food and drinks. However, challenges such as worker fatigue and human error often interfere with service. To overcome these problems, this research developed an intelligent waiter robot named Deqorel. Deqorel is designed to improve restaurant service efficiency through trajectory sensor-based automatic navigation and optimization algorithms. Deqorel is equipped with a 15-inch interactive screen, an energy-efficient DC motor, and a lithium-ion battery that supports operations for long periods of time. The robot frame uses 304 stainless steel with stress calculations to ensure strength and safety. The results show that Deqorel is able to provide accurate, fast, and responsive service in a dynamic restaurant environment, thereby increasing customer satisfaction as well as restaurant productivity.

Abstract

Liquid smoke is the result of pyrolysis of various types of biomass used in various industrial applications, including food preservation and waste treatment. This study aims to design and test a liquid smoke production device with a capacity of 120 ml per hour using six types of raw materials: coconut husk, coconut shell, straw, rice husk, corn cob, and corn stalk. The graph of the test results shows that the second experiment (test 2) produced a higher volume of liquid smoke than the first experiment (test 1), with the maximum volume reaching 310 ml. Nonetheless, the processing time varies depending on the type of raw material used. The results of this study show that optimizing the pyrolysis process can improve the efficiency of liquid smoke production, both in terms of volume and processing time. Thus, the device design used in this study has the potential to be further developed to increase production capacity and efficiency. Keywords: liquid smoke, pyrolysis, equipment design, production capacity, coconut shell.

Abstract

This study aims to analyze the strength of the 20-ton capacity welding test equipment frame using SolidWorks software-based simulation. The simulation evaluates the stress distribution, strain, and safety factor of the frame structure when receiving the maximum load. Analysis using the finite element method (FEA) is performed by modeling the frame along with boundary conditions and loads that match the actual test conditions. The simulation results show that the maximum stresses in the structure are still below the yield limit of the material, so the frame is considered safe to use. The highest stresses are distributed at the top of the frame especially around the load application area, while the bottom and legs of the frame experience lower stresses. The minimum factor of safety obtained in the simulation is 6.6 which indicates that the structure has high reliability against the applied load. Based on these results, the welding test equipment frame design can be said to be strong enough and safe to use for testing with a capacity of 20 tons. However, design optimization can still be done to improve the strength of the structure.
