In the standard operating system, the input parameters such as changes in the mechanical torque of the turbine and changes in the field voltage of the amplifier from the exciter need to be considered. Some studies that can be done include the study of the dynamic stability of synchronous generators when dealing with small changes that occur using the eigenvalue approach which is the roots of the characteristic equations of the system state space equation. The eigenvalue can show information on system stability and is related to the response of time to changes in the system. The system used is in the Sulselrabar electrical system. From the simulation results show the characteristics of the system in terms of the frequency response and angle of the generator rotor. For the eigenvalue system value in the inter-area oscillation mode is -0.33293 + 4.0844i, for the oscillation mode it is -0.9043 + 7.9670i. While the generator frequency response, where oscillations occur before reaching steady state conditions. The biggest overshoot response occurs in Old Tello plants, with a maximum overshoot of 0.09124 pu and a minimum of -0.2227 pu. While the smallest overshoot response is found in the Bakaru hydroelectric power plant which is equal to 0.004681 maximum pu and -0.02563 minimum pu.

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.

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%.

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

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.

The transmission network is an important part of the power system to deliver electrical energy from the power plant to the load, therefore the power system must be maximized to achieve optimal power flow, Unified Power Flow Control (UPFC) is one of the Flexible AC Transmission System (FACTS ) capable of controlling the power of the transmission line separately on electrical transmission and can be mounted on both the sender and the receiving end of the power. The UPFC power injection model to the transmission line is made in a power flow equation. In the Java Bali (Jali) 500 kV system analyzed by the Genetic Algorithm method, to produce a power injection that minimizes the active and reactive power losses of the transmission line without exceeding the UPFC device limit. In the Java Bali (Jali) 500 kV system analyzed by Genetic Algorithm method, the optimum UPFC value of Reactive Power injected to the system for bus 39 is 9695.593207MVar, bus 15 is 10598.78754 MVar, and on bus 37 is10755.88608 MVar. The total loss of channel power on the system prior to installation of UPFC is1815.775809 MW, while the total loss of channel power in the system after installing UPFC with GA is1537.391648 MW.
