Abstract

Black Soldier Flies (BSF) maggot business got increasing attention nowadays, especially dried BSF maggot. The dried BSF maggot is very suitable for fish feed, thus dried maggot business has good prospectus not only in terms of financial sector but also in terms of waste management sector. Unfortunately, making dried maggot requires high cost during drying process, since additional cost for LPG is needed. It is important to replace LPG fuel by less expensive one, such as biomass fuel. Indonesia has huge potential of biomass energy sources which mainly come from agricultural, forestry, and industrial waste. The present work aims to investigate techno-feasibility of rice husk and waste scrap waste as feedstock of rotary drum drier. The experimental work is conducted by drying 10 kg fresh BSF maggot for 2 hours in the drier using blend feedstock of 6 kg rice husk- 6 kg wood scrap (RH-WS) and feedstock of 12 kg wood scrap (WS). The results depict that the waste of rice husk and wood scrap are technological feasible as energy sources for rotary drum dryer while drying BSF maggot. The performance of the drier in terms of drying rate, drying heat, specific fuel consumption, and drier's effectiveness is better when a blend of rice husk and wood scrap is used as a feedstock. The values of drying rate, drying heat, specific fuel consumption, and drier's effectiveness when using blend feedstock are 0.92 g/s, 20996.37 kJ, 27940.15 kJ/kg, and 0.67, respectively. It is recommended to use waste of rice husk and wood scarp in blending form to obtain optimum performance of the rotary drier while drying BSF maggot.

Abstract

A one-axis shaking table soil liquefaction simulator is utilized to study soil behaviour and characteristics, enabling efforts to mitigate liquefaction-indicated soil behaviour. Traditionally, the process of measuring and documenting building settlement, which is a soil variable that indicates liquefaction, involves the use of a pen, paper, and measuring instrument. Therefore, build a measurement system consisting of LVDT displacement sensors and NI cRIO-9025 as the main components, along with LabVIEW software as a novel medium to acquire, process, display, and record measurement data to provide increased measurement accuracy equivalent to traditional instruments. The soil used as material in the test was represented by silica sand with a density percentage of 40-70%. By utilizing the measurement system uses a linear regression scaling method with a sampling time implemented during testing with 100 ms or 10 data/second and descriptive statistical analysis, the soil liquefaction simulator achieves precision with an average measurement error of ±0.89 mm and a reporting operational time efficiency rate of 95.80%. Thus, the accuracy rate of the simulator with the method used in the system is 96.31%.

Abstract

A PWM rectifier is a power converter that functions to convert alternating current into direct current using pulse width modulation (PWM). The baseplate is an important part of the PWM rectifier box, which acts as a stack module holder and has an important role in maintaining the stack module and increasing the power conversion efficiency and reliability of the train traction system. This study aims to determine the effect of variations in material and plate thickness used on Von Mises stress, deformation, and safety factors as well as the mechanical properties of the designed baseplate. The research method used is finite element analysis (FEA) by doing 3D modelling using CAD software and a simulation process using computer-aided engineering (CAE) software with material and plate thickness variations. The results obtained the best baseplate based on the value of Von Mises stress and minimum deformation, as well as the maximum safety factor, namely the baseplate with SS400 material with a plate thickness of 5 mm, with a minimum Von Mises stress value of 76.374 MPa, a minimum deformation value of 0.13611 mm, and a maximum safety factor value of 3.1424. It indicates the effect of material and plate thickness on the value of Von Mises stress, deformation and the resulting safety factor, thus affecting the mechanical properties of a good and safe baseplate in maintaining the performance of the stack module.

Abstract

This research focused on the development of an animal feed mixer machine to improve mixing capacity. The research used an experimental model and involved need analysis, design, development, implementation, and evaluation. The goal was to determine the optimal rotational speed of a stirrer screw for different types of animal feeds as well as understand the stages of making the machine and its working principle. The process involved manufacturing the frame, shaft, transmission, screw fins, sheet metal process, and assembly. The results shows that the animal feed mixer machine with a stirring speed of 312.3 rotations/minute was able to produce 958.3 kg of feed in one hour. This stirring speed provides the best fuel consumption, which is 676.5 ml/hour. The mixer has a safe element on the reduction shaft, with 115.8 kg.mm of torque and 5.82 kW of power. Thus, this mixer is an efficient and productive solution for the animal feed industry.

Abstract

Longline is widely used by fishermen in Indonesia. The use of longlines, which require fishermen to go back and forth periodically to check the catch, creates problems of time and fuel.  This research aims to develop a fishing tool for fishermen that will be more efficient in terms of time and fuel. The method used is a literature study related to the components to be used, the design of electrical, mechanical, interfaces and microcontroller programs, as well as the assembly of components and testing tools. The research was conducted from March to July 2022 at the Batam State Polytechnic with the test site at Nongsa Beach, Batam City. The result of this research is a smart longline prototype that can detect fish pulls using accelerometers as vibration detectors on each hook, and locate them using GPS features processed by the Mappi 32 microcontroller using LoRa communication. The information is displayed on the fishermen's smartphones. This allows the fishermen to monitor their catch without having to regularly check the longline. This tool is also equipped with a solar panel as a power source allowing it to operate for 25 hours above sea level. A future proposal for this research includes making a smart longline capable of detecting the species of fish caught. This would help fishermen analyze the species of fish in the water.

Abstract

3D printing technology is rapidly growing in the industrial world, especially with the Fused Deposition Modeling (FDM) method that uses thermoplastic filament filaments. The manufacture of these filaments requires extrusion machines and plastic seeds, with filament diameter as the main indicator of 3D Print quality. This study aims to analyze the effect of variations in heating temperature on the consistency of the diameter of the results of extrusion machines for High Density Polyethylene (HDPE) plastics at temperatures of 160°C, 180°C, 200°C, 220°C, and 240°C and Low Density Polyethylene (LDPE) at temperatures of 160°C, 170°C, 180°C, 190°C, and 200°C. Each temperature variation has six filament samples, with the diameter measured every 1 cm for five measurements using a screw micrometer, resulting in 30 data per temperature variation. The data is processed using Statistical Process Control (SPC) and Capability Process methods. Based on data analysis with control chat, it can be concluded that each temperature variation produces diameters that are within the control limits, allowing capability process testing. Process Capability has been conditioned, resulting in large process variations compared to the established specification range, indicating imbalances and inconsistencies in filament production so that filament diameters are often out of specification limits. The conclusion of this analysis is that temperature variation has a significant effect on the consistency of filament diameter resulting from extrusion machines with HDPE and LDPE plastic seed materials. In addition, based on variations in temperature data that produce the best filaments, the temperature is 220°C for HDPE plastic and 190°C for LDPE plastic.
