Characteristic I-V of photovoltaic is depended on solar irradiation and operating temperature. Solar irradiation particularly affects the output current where the increasing solar irradiation will tend to increase the output current. Meanwhile, the operating temperature of photovoltaic module affects the output voltage where increasing temperature will reduce the output voltage. There is a point on the I-V curve where photovoltaic modules produce maximum possible output power that is called Maximum Power Point (MPP). A technique to track MPP on the I-V curve is known as Maximum Power Point Tracking (MPPT). In this study, the MPPT has been successfully designed based on Adaptive Neuro-Fuzzy Inference System (ANFIS) and integrated with solar tracking system to improve the conversion efficiency of photovoltaic modules. The designed ANFIS MPPT system consists of current and voltage sensors, buck-boost converter, and Arduino MEGA 2560 microcontroller as a controller. Varying amounts of lamp with 12V 10W rating arranged in series is used as load. Solar tracking system that is equipped with MPPT ANFIS able to increase the output power of photovoltaic modules by 46.198% relative to the fixed system when 3 lamps is used as load.

Safety is an essential requirement in the course of production in the industry. Security in the factory needs to be considered, especially against malicious nodes such as burner. In this research analysis to determine opportunities hazard that could happen to superheat burner. The magnitude of the risk of harm must be balanced with the security system (SIS). So the system superheat burner analyzed by the method HAZOP and SIL safety level calculated through the method of FTA. Based on research conducted in this thesis, superheat burner has a high danger risk (high risk) component TT-1005 and PT-1018. The level of security superheat burner classified SIL 1 with PFD 4.38x10-2, so do redesign the SIS to achieve SIL 2. PFD system of 0.0099 is achieved by adding 2 ESDV on line check fuel gas and purges gas and increase the pressure switch on each function pressure switch. (PSHH, PSL, PSLL).
