Open Access (OA) literature is digital, online, free of charge, and free of copyright and licensing restrictions. Open Access Journal is one of the Open Access (OA Gold) used in the process of publication of journals through the Internet. Open Access Journal allows users to maximize the process of publishing that are peer-reviewed. Peer-review process conducted by the Authors, Editors, and Reviewers journals become a registered user on the Open Access Journal. Open Access models are used to simplify the process of publication of journals that are closed and takes a long time and reduce storage space for publications. With Open Access, users such as author, editor, or reviewer can make the process of writing and editing the journal on the media that can be accessed anywhere and anytime. To model of Open Access use web applications development approach is UML - based Web Engineering (UWE). UWE UML provides a graphical notation that depicts the elements of the model, which supports the generation method of semi - automatic, and the process of web development life cycle.

Renewable energy resources are currently being developed in Indonesia. The government is also targeting renewable energy mix of 23% to be achieved in 2025. Solar Photovoltaic Generation System is one of a form of renewable energy that is currently being developed in Indonesia. Several industrial estates in Indonesia are filled with factories with fairly large buildings and have great potential for the development of Rooftop Solar Photovoltaic with the advantage of reducing land investment costs and of course without reducing the functionality of factory operational. The purpose of this research is to simulate the technical and economic performance of Solar Photovoltaic on grid 200kWP installed on the roof of a factory building using Helioscope software in an industrial estate area in West Java. The simulation results show that the average value for Global Horizontal Irradiance (GHI) is 138.2 kWh/m2, Electrical Energy Production is 21,977 kWh, and the Performance Ratio (PR) in one year is 78.06. Meanwhile, the total annual Electrical Energy Production is 263,723.6 kWh. The total investment value of the Rooftop Solar Photovoltaic on Grid system in this factory building is Rp. 2,457,850,800. Based on the economic feasibility study made, it can be concluded that the Rooftop Solar Photovoltaic on Grid system with a power of 200 kWP in the factory building is economically feasible as long as the interest rate is less than 12.71% (Internal Rate of Return/ IRR).

Environmental damage can be caused by an imbalance of the earthâ€™ constituent elements, which one of the elements is scarcity of clean water in the earth. Dearth of clean water is predicted that will be experienced more than a half of word population of nine million of human being in 2050. The phenomenon of the scarcity of the clean water has been occurred especially in Indonesia that it is a country which has six percent of the potential of the clean water, but in fact it shows the need of the clean water of Indonesia population are still not enough. The dearth of the clean water needs to get serious attention from all stake holder, included people in the boarding school. An effort to decrease the scarcity of the clean water rate is by behaving frugally in using the clean water. To do that need to do socialization massively to the people and it require a long time. Therefore, beside the socialization massively, engineering to decrease the flow rate in using the clean water through the valves that is by applicating flow control method. This simple technology of flow control application, the community service team and Nurul Haramain boarding school located in Kampung Saitem, Ciburayut, Cigombong, Bogor, West Java are collaborated. A measurement result of flow rate before the flow restrictor is applicated in the valve is 7.76 liter/minute and after applicated decrease to 1.13 litter/minute. Percentage of decreasing is to reach 83 percent.

Renewable energy is growing, one of which is by controlling solar energy. A solar power plant (PLTS) is a power generation system that utilizes solar energy to become electrical energy through photovoltaic modules, which are included in environmentally friendly energy so that it becomes a renewable, effective, more efficient, and reliable plant. The research designing the modeling of PLTS on a grid was carried out on the roof of a gas power plant (PLTG) which generated 164.47 MWh / year. Analyzing modeling in the addition of the Rooftop Solar System that enters the network can reduce exhaust emissions from the use of other equipment for four years with an average of PLN by 99.29%, PLTG #1 by 99.06 and PLTG #2 by 99.11%. The impact of the addition of the PLTS Rooftop on the quality of power entering the 3.3 kV network system is seen that the feeder 2-panel bus has improved to 97.82% of the voltage drop of 72.67% in line with the PLN 3 panel, the improvement is made by providing capacitors of 3x4Mvar. Feeder 3 improved to 97.61% of the voltage drop of 78.87%, in line with the PLN 4 panel. The improvement was carried out by providing a capacitor of 2x4Mvar. Panel feeder four was seen to have improved to 99.21% from an excess voltage of 109.23% in line with the generating equipment, and the improvement was made by reducing capacitors by 0.1 Mvar from the used 5x0.1 Mvar.

Water level control and pressure control are implemented in many at several industrial processing such as water dam, petrochemical processing plant, pharmacy and food processing plant, overhead tank, waste processing plant, electricity plant, etc. This study analyses a simulation and a needed components for automatically water level control system implementation using programmable logic controller (PLC). The water level control using PLC is designed to control the water level and prevent waste the water from a water tank. PLC is one of devices of automated controller which mostly used. Use of PLCs in industries are indispensable to control parameters which required high precision. In this research studies water level control system using PLC as primary controller and human machine interface (HMI) as remote controller that could visualize state of a system work (plant) in real time on computer screen and could gather field data as well. Main device for this research is Omron PLC CP2E type and touchscreen HMI Omron. At the prototype is used a water tank and a water container (to be one with the water resource), and in the HMI is showed the pages of home, control panel, and plant. From the result of the diagram ladder and the HMI design are got the system run well. The application from this research could be learning media in the system control laboratory for the subject of industrial control system and the others, related to it.
