Abstract

Lightning rods in the Laboratory of Energy and Protection Distribution System of Ujung Pandang State Polytechnic are not functioning properly so the resistance resistance tends to be large, this is not good for earthing. This problem can be overcome by remaking lightning rods on wet and dry soils. This activity was carried out to reduce the value of resistance resistance in connection with this, this activity was carried out by designing, assembling and collecting data carried out by testing, while data analysis was carried out by counting. Based on the results of the discussion concluded that the resistance resistance value obtained is smaller than the previous device. Evidenced by the results of the test where the resistance value on the rod electrode in dry conditions ranged from 1.56 to 2.40 Ohm while the previous tool ranged from 1.6 to 9.0 Ohm. Then for wet soil conditions that range from 0.45 to 1.29 Ohm, while the previous tool is around 1.8 - 5.25 Ohm

Abstract

Biogas is an alternative energy in the form of gas formed from the process of fermentation of organic materials. One of the most abundant organic materials is water hyacinth. This research aims to design the tool that will be used to process water hyacinth so that it can produce biogas energy. The main components of the equipment made consist of digester, water trap, gas container, and gas stove, each made 3 appliances. The experiment was conducted using 3 pieces of digester where each digester was filled with 10kg of water hyacinth and different starter. Digester A uses a 0.5 liter EM4 starter mixed with 4.5 liters of water. Digester B using starter 5 kg of cow dung mixed with water 3 liters. And digester C using starter 5 kg of cow dung mixed with 0.5 liters EM4 and 4, 5 liters of water. Then see the development of biogas during the fermentation process (35 days). From the results of this study can be obtained biogas pressure, temperature, acidity (pH) and the duration of the flame generated by the means of producing biogas using this digester and can be applied to the stove. The pressure change produced by digester C is greater than the pressure generated from digesters A and B. The temperature changes produced in digester C are greater than the temperature produced by digesters A and B. The initial pH value of mixing for digester A is pH 6.3, digester B with pH 7.5 and digester C with pH 5.5. The pH value after biogas was produced for digester A with pH 7.5, digester B with pH 7.5 and digester C with pH 7.6. This corresponds to a good pH for the growth of biogas-forming microbes, ranging from 6.4 to 7.8. The fire generated on the blue flame test, with the total length of the flame for each digester is 54 minutes 46 seconds.

Abstract

Power flow study is the determination or calculation of the voltage, current and power factor or reactive power that is present at various points in a power grid in the normal state, whether current or expected to occur in the future. From the result of normal condition analysis, it is obtained the critical voltage profile on bus 31 tonasa and used as the candidate for mounting capacitor. From the calculation results obtained capacities installed 16.0413 Mvar. From the simulation results before the installation and after installation of the capacitor visible improvement of voltage profile and channel losses. The channel losses prior to installation are 32,649 MW and after installation of 31,834 MW. For voltage profiles, some buses also look better, than before in critical conditions to be marginal. On the previous bus tonasa 0.933 pu to 0.953043 pu

Abstract

Photovoltaic (PV) is a device which is capable to converts solar irradiance into Direct Current (DC) electricity energy. To increase the power result of PV, it needs a method to track the Maximum Power Point(MPP) which is usually called Maximum power Point Tracking(MPPT). So that, the power result increased with low cost. The purpose of this research is to conduct MPPT modeling by Particle Swarm Optimization (PSO). The proposed method is implemented in DC to DC converter. This research used SEPIC converter. The purpose of using SEPIC converter is in order the output of current and voltage have smallest ripple. The modelling system is conducted by using MATLAB 2016b software to find out performance of PSO and SEPIC converter. The evaluation of PSO and SEPIC converter performance has been done. The simulation result shows that the proposed system has been working very well. The PSO has good accurateness in tracking and capable to to track the power produced by PV with velocity around ±4,2 seconds when in conditions STC, ±9,2 seconds when in conditions partial shading, despite a fluctuating irradiance change. While in SEPIC converter is able to reach efficiency of ≥ 80%.

Abstract

The role of boiler machines at PT. SPINDO in the galvanize pipe production process is very important, where the steam produced by the fire tube boiler machine is directly distributed into the blow system for the cleaning of the remaining galvanic in the pipe and heating the water for pipe washing. To determine the efficiency of the boiler, a direct method is used to analyze the efficiency of boiler machines and indirect methods as a way of calculating the amount of efficiency if an economizer is installed. The efficiency of diesel-fueled boilers using the direct method yields an average yield of 40.7% (forty point seven percent) and 45.84% (forty five point eighty four percent) for gas-fired boilers. However, by using an indirect method, efficiency if installed economizer is obtained at 85.55% (eighty five point fifty five percent) for diesel-fueled boilers with a capacity of 5 tons and 81.76% (eighty one point seventy six percent) of the efficiency of a gas-fired boiler with a capacity of 2 (two) tons. Efficiency improvements can also be done in many ways, including maintenance of a good and scheduled boiler machine for good boiler feed water treatment.
