Abstract

Natural fibers have advantages compared to synthetic fibers because they are biodegradable and sustainable. The problem with natural fibers is the extraction or separation process of the skin and fiber. This research aims to design a decorticator that separates leather and natural fibers to be used as composite reinforcing materials. The procedure for creating a decorticator machine is carried out by collecting initial data and requirements about the decorticator machine, determining effective decorticator machine technology and mechanisms, designing concepts and mechanisms, and planning detailed drawings. From this research, a decorticator design was created with a frame component that functions as the primary support for the machine components; the beater shaft functions to scrape the stem by moving quickly and breaks the outer layer of the stem so that the fibers can be separated, the rolling cylinder functions to hold the fiber during the process of separating the fiber and stem, the machine cover functions to provide safety during operation, the petrol motor as the driving force, and the pulley-belt transmission system. Apart from separating fiber from non-fiber parts, decorticator machines can also increase the use of environmentally friendly natural fibers as composite materials and reduce dependence on synthetic materials.

Abstract

The aim of this final assignment is to design an animal feed grass chopper machine using an electric motor drive system and to determine the production capabilities (on machine activity) of the grass chopper. This machine is a multi-purpose machine as a forage designer, especially used to design animal feed grass. In making this final assignment, the author chose the title of designing an animal feed chopping machine using an electric motor system to save time. Seeing that there are still many people who currently chop animal feed using manual tools and this will require a fairly long process, of course, having an animal feed chopper machine that uses an electric motor can shorten the time in the process of chopping animal feed. Therefore, the creation of this final assignment can make work easier and can save time so that workers can complete it more quickly. The initial process for operating an animal feed chopper is to connect the dynamo cable to an electric current, then take the elephant grass and then insert it into the inlet of the grass chopper. This tool is capable of producing grass chopping of 0.94 grams/1 minute 42 seconds. The driving source of this tool uses a 1/2 HP DC electric motor with a rotation of 2800 rpm. The conclusion of this final project is how to design an animal feed grass chopper consisting of a frame, a dynamo with 220 Volt power and a battery current of 3.54 A. The application used to design this tool is sketchup, the tools and materials used include grinding, meter, welding transformer, welding glasses, electric drill, angle rule, hammer, L profile iron, plate iron and bolts. Test results of the tool and working voltage of 220 Volts, maximum speed of 2800 rpm, chopping results of 0.94 grams/1 minute 42 seconds of operation using a cable from a dynamo to electric current and a 220 Volt power source. Our suggestion is to develop this tool in terms of the transmission system, the engine output rotation is still very large, making the grass chopped results very small. So we need a machine speed control device (variable speed) so that the chopping can be adjusted according to the required speed.

Abstract

The power plant (PLTU Nii Tanasa) is located in Nii Tanasa Village, Soropia District, Konawe Regency, Kendari - Southeast Sulawesi. This 17.64 ha PLTU consists of 2 units, each producing 10 MW of electricity. The steam power plant system requires a water treatment system to change the water content from sea water to demin water or fresh water (WTP). Water treatment systems in the steam power plants are important to ensure efficient and sustainable operation. The water used in the steam cycle must be of high quality to prevent damage to boilers, turbines, and other components. The stages of water treatment include: Pretreatment, Demineralization, Degasification, Chemical Dosing, blowdown, condensate polishing, cooling water treatment. In the Water Treatment Plant process, the water conductivity is reduced to < 1 μs, this is done so that the electrical conductivity contained in the water is very small so as to minimize the potential for corrosion, and other oxidation processes. In addition to pH, the other parameters of boiler fill water are TDS, and water pH. The types of maintenance observed in this activity are preventive maintenance, and corrective maintenance. Preventive maintenance includes Sea water pump components, multimedia filters, active carbon filters, micron filters, HP pumps, SWRO. The corrective maintainaice in this observation includes micron filter equipment, SWRO, BWRO. The component maintenance process of the WTP has a direct effect on water quality so that it is related to the performance of the Pwer plant for both in terms of thermal performance and economical aspects.

Abstract

A pump converts the rotational energy of the shaft and subsequently the movement of the blades into kinetic energy and pressure in the fluid. Pumps can be configured as single, double series, or double parallel, depending on the requirements. This research aims to determine the best performance of a centrifugal pump installation with variations in head and configuration. The method used in this research is experimental, utilizing a centrifugal pump arranged with water as the fluid. The results show that single and double series configurations are more suitable for applications requiring stable flow despite changes in head. Parallel configurations produce higher speeds compared to single and double series configurations, but speed decreases with increasing head. The single pump's efficiency increases to 40.5% with an increase in head. Efficiency in the series configuration increases to 50.1%, higher than the single pump at the same head. Efficiency in the double parallel configuration increases to 80.1%, indicating that the parallel pump is the most efficient at higher heads. For applications requiring high efficiency, the double parallel pump configuration is the best choice. Based on the analysis results, it can be concluded that the double parallel pump configuration provides the best performance with the highest efficiency at 80.1%, and the highest discharge rate of 43.2 l/min. The double parallel pump configuration is the most efficient and effective for applications requiring optimal pump performance at higher heads.

Abstract

The bioflock catfish farming method presents advantages in terms of enhancing feed efficiency and reducing chemical usage. However, it faces challenges in higher energy consumption compared to conventional methods. Additionally, not all farming locations are situated near residential areas and connected to the PLN grid; some are located in remote areas without PLN grid access. This study aims to assess the potential and effectiveness of renewable energy utilization using HOMER Pro for bioflock catfish farming in Pandeglang, West Java. Pandeglang has an average solar radiation intensity of 5.27 kWh/m²/day and an average wind speed of 4.99 m/s, making it suitable for the utilization of solar panels and wind turbines as renewable energy sources. A bioflock catfish farming operation with a capacity of 2 tons per cycle requires 13.14 kWh/day of energy, with a peak load of 1.74 kW. Using HOMER Pro, this study explores 11 scenarios with various generator configurations. The most optimal scenario involves the use of solar panels with a capacity of 1.58 kW combined with energy from PLN, resulting in a renewable energy utilization rate of 39.2%. The cost of energy produced in the optimal scenario is Rp 1,019.00/kWh, with an Internal Rate of Return (IRR) of 20%, a Return on Investment (ROI) of 16%, and a Break-Even Point (BEP) of 5 years. The best scenario yields a Net Present Cost (NPC) of Rp 81,100,000, which is 19% lower than the baseline scenario's NPC of Rp 100,000,000 over the 20-year project period.
