Abstract

Stripping the betel nut using a machine is considered to be more effective than manually, based on this I designed an automatic betel nut peeler control device using Arduino Mega as a mechanical and electrical system controller. In the design of this tool using a hollow iron frame material with 40X40 mm, with a length of 130 cm and a width of 30 cm. Furthermore, this tool is planned to be able to work with a capacity of 20 Kg/hour. After all components are completed, it will proceed to the tool development process to be able to perform performance tests. After testing, stripping using the manual method takes a relatively longer time, which is 11 minutes. While using the machine only takes 6 minutes. In this test, 1 kg or 74 young betel nut, yellow areca nut, dry areca nut, and wet old areca nut were used.

Abstract

This research is about comparing the efficiency of a laboratory-scale steam power plant with coconut shell charcoal as fuel. The test was carried out at the STITEKNAS Lab – JAMBI, with the data obtained in this test were steam power, shaft power and electrical power. The error in this study aims to determine the effect of pressure on the performance of a coconut shell charcoal power plant. steam used by wet steam researchers. The research methodology uses variations in combustion pressure (1,2 and 3 bar) to obtain research data.,From the test data of laboratory-scale research results with coconut shell charcoal as fuel, variations in combustion pressure in the furnace that the greater the combustion pressure will produce the higher combustion chamber temperature, the largest at a combustion pressure of 3 bar produces a combustion chamber temperature of 746 °C and the smallest at a pressure of 1 bar of 883.75 °C and from the calculation of research data obtained results of laboratory-scale steam turbine efficiency with coconut shell charcoal fuel the higher the combustion pressure the higher the power produced, the highest input power at a combustion pressure of 3 bar with a value of 27.26 watts and the smallest at a combustion pressure of 1 bar with a large input power of 22.94 bar, while in the calculation of efficiency, the efficiency of the combustion pressure is that the turbine efficiency is higher than the efficiency of the generator. 18% and at a combustion pressure of 3.Bar the lowest efficiency is obtained, namely the turbine efficiency of 51.36% while the generator efficiency is 17.5%, so that the increase in combustion pressure cannot increase the efficiency of the turbine and generator.

Abstract

This research aims to design a measuring device for the speed and strength of kicks and punches in martial arts so that the quality of kicks and punches can be measured objectively. The types of taekwondo kicks that were tested were ap chagi and yeop chagi as well as yeop jireugi and momtong jireugi punches. This research was conducted in several steps, namely: literature study, preparing tools and materials, designing and modeling, making tools and testing and analyzing data. The way this tool works, the respondent kicks or punches the foot boxing pad that has the FSR sensor installed. At the same time the time is started by pressing the start button. After making a kick or punch, the time will be stopped by pressing the stop button. The pressure and time will be read by the NodeMCU ESP32, the data will be sent via bluetooth to the Blynk application and displayed with the TM1637. The results of the research "designing a measuring device for measuring the strength and speed of kicks and punches in martial arts with a force sensing resistor (fsr) sensor and NodeMCU ESP32" are: The average kick speed of ap chagi and yeop chagi is 0.10625 m/s and 0.0786 m/s. Meanwhile, the average speed of yeop jireugi and momotong jireugi are 0.1667 m/s and 0.0917 m/s, respectively. The average athlete has a kick power of ap chagi, yeop chagi, yeop jireugi and momtong jireugi is medium.

Abstract

Electrical energy is one of the most needed energy. The sun (sunlight) is a renewable energy that can be used to generate electrical energy. Indonesia is a tropical country, so there is quite a lot of sunlight available. In order to obtain efficient and safe (consistent) electrical energy, backup solar energy can be used with PLN's electrical energy using a hybrid system. The planned hybrid system uses 100 WP Poly-crystalline solar panels (2 pieces), 100 Ah 12 V batteries (2 pieces). The hybrid controller system uses a 1000 watt hybrid inverter. Applications that are designed to be used as labor lighting lamps (10 pieces) that require 1000 watts of power.

Abstract

Palm oil is one of the choices of growth companies in Indonesia as biomass energy. Biomass is organic matter made from plants and animals that contain energy. The result of the palm oil processing process is liquid and solid waste.Liquid waste in the form of sludge can be reprocessed into pure palm oil with several treatments.Solid waste in the form of shells and fibers (fibre) derived from palm pulp is used as fuel in boilers and used as steam steam for the process of generating electricity through turbines. Research on the utilization of solid palm oil waste fibers and shells was carried out at PT. Nusantara Plantation VI PKS Bunut because of its large waste potential as an alternative fuel source (renewable energy. Processing capacity of the plant of 30 tons of FFB/hour produces 3.9 tons of fiber solid waste and 2.1 tons of shells, the total solid waste as fuel is 6 tons/hour. The fuel requirement of the plant is 4.55 tons/hour so that there is a difference of 1.45 tons/hour. The electrical energy generated from the utilization of 6 tons/hour of fuel is 776 kW/Hour, while the realization energy used by the factory is 750 kWh/Hour.There is an excess energy of 2.6 kW/hour. This indicates that the use of shells and fibers as fuel for new and renewable energy at the PLTU PKS Bunut PT. Nusantara VI plantations are very good.

Abstract

The continuity of electrical energy requires an electric energy management with high efficiency and easy-to-obtain fuel. One of them is the Ombilin Steam Power Plant (PLTU) with a capacity of 2 x 100 MW. At ombilin power plant there is a system of its own use that is obtained from the generator when the plant is operating. In this study, contingency analysis was conducted on its own system simulated using ETAP 12.6 software. Contingency analysis is the study of the safety of an electric power system by conducting a power flow analysis of the impact of a number of contingency cases such as the release of one or more generators and the release of one of the tramsmission elements. With contingency analysis, an electric power system will be able to calculate the disruption that occurs for example in the use of a power plant unit, so that it can predict changes in system capacity and the remaining bus voltage whether it can still be burdened or has experienced overload conditions. In this study, a contingency analysis was conducted on the Ombilin PLTU's own usage system with 5 scenarios to see the results of voltage and performance index (IP) when contingencies occurred with 5 scenarios then ranked. Based on the results of 5 scenarios, the highest voltage obtained in scenario-3 is 6.18 kV with a performance index (IP) of 2.4915 and the lowest voltage in scenario-4 is 6.13 kV with a performance index (IP) of 3.1526.
