Meanwhile, the industrial demand for plastics is also increasing. So we need a recycling business that can bridge this. Plastic waste in the environment can be decomposed, and the industry fulfills plastic needs at low prices. This study aims to analyze and optimize the business of recycling plastic waste into plastic ore to reduce the amount of plastic waste in the environment and obtain material benefits. The research method used is a case study in a plastic waste processing company with the collection of data needed to determine the formulation of the problem so that a mathematical model of linear equations can be formed, which then, through production simulations, will be obtained optimization. The results are then analyzed with a techno-economic study to determine the feasibility of the business.After optimization of production from simulations based on a mathematical model of linear equations, if the company wants to get maximum profit, then the company must produce PP Black A of 1022.73 kg, PP Black B of 852.27 kg, PP Gray of 625 kg. Meanwhile, PP Gray Jumbo should not be produced.

The most significant risk in this sector is fire. To support the oil and gas production activities, it is necessary to install permanent and non-permanent fire extinguishers to prevent and deal with fire accidents. The firewater network system has a role in supplying flow rates with a certain pressure to protect the production process in a fire. The flow rate and pressure must be able to preserve the process area. Therefore the performance of firewater network system must be monitored. Over time, the performance degradation of the firewater network system is unavoidable. This decrease is due to scaling or leak minor at pipe and the decreasing performance of the diesel fire pump.This research aims to create a model of simulation fire water network system using newton-raphson iteration. The simulation model that is formed will be used to vary the flow rate against pressure. Based on iteration show the flow rate at platform 4 is 198.9 m3/h. The discharge variation is carried out to see the pressure on platform 4, the variation of the discharge of 2,000 m3/h gives a pressure of 150.45 psig, the variation of the discharge of 1,500 m3/h gives a pressure of 130.85 psig, and the variation of the discharge of 500 m3/h gives a pressure of 24.26 psig. The results of the discharge variation are used to see the performance of the fire water network system.

Every day as much as 60% of greywater is wasted as a by-product of human consumption. Filtration using local media becomes the treatment option. The size of the greywater particles ranges from 10 μm to 100 μm. The filter media size is made into two levels i.e., 80 mesh (active zeolite and charcoal) and mesh 18 (active sand) to filter particles by ten μm and mesh 14 (zeolite and activated charcoal) and mesh 10 (activated sand) to filter the particle size of 53 μm. The combination of filter media thickness in three experiments took one of the filter media to be used in each experiment. Each experiment will be used one filter media with a thickness of 50 cm and 25 cm each for supporting filter media, with a total media thickness of 100 cm.All of the above become independent variables in research. While the dependent variable is water quality standard in accordance PP. 82 the year 2001 with the main parameters are BOD, COD, TSS, pH, and detergent. The flow rate is set at 24.55 ml / m2 min. Besides the quality standard, the research still refers to cost efficiency and processing time (filtration). All variables consist of 6 filters that give different results; in laboratory test control, only pH fulfills the quality standard of PP. 82 of 2001.

Therefore, in West Papua, it is necessary to fix this electricity problem where the most significant source is still from fossils. By looking at potential sources in West Papua that are more sustainable and renewable to meet public electricity demand in West Papua.In this study, LEAP software will simulate several scenarios, namely based on data from the RUPTL (Electricity Supply Business Plan) and further digging based on the potential literature in West Papua. There will be three scenarios; scenario 1 uses BAU (Business as Usual) as available in RUPTL. Scenario 2 uses BAU data and adds potential renewable energy. Scenario 3 is not using fossil energy but using renewable energy. The result is West Papua can be 100% electrified in 2025 if using scenario 2. The potential for renewable energy in West Papua is wind and sun. However, it does not rule out other sources, such as hydropower.

The potential for wind power plants can be developed in 3 districts in the southern part of Yogyakarta, bordering the Java Sea, to be converted into hydrogen through an electrolysis process. The three research locations were Bugel Beach in Kulon Progo, Pandansimo Baru Beach in Bantul, and Baron Techno Park at Baron Beach in Gunung Kidul. The selection of the most optimum location was made employing the Analytic Hierarchy Process (AHP) method by considering three factors, namely technical, location, and socio-economic factors. The first factor includes the potential for electricity generation from wind power and the available land area. The second one consists of sub-factors, namely access to the location and the distance to the PLN electricity distribution line. Then the last one includes conflicts with tourism and the economic activities of the surrounding community. After obtaining the most suitable location, planning is carried out for the wind farm that is built, the amount of electrical energy produced, the cost of generating electricity, and the cost of producing hydrogen from the electrolysis process.

Research methodology starts from the data observed laboratory test results for samples of hospital wastewater. From these data, it is known that the levels of phosphate and ammonia still do not meet quality standards following the Decree of the Minister of Environment No. 58 of 1995 regarding effluent standards for hospitals. Further research is limited only focused on decreased levels of phosphate and ammonia in hospital wastewater.Data research includes a phosphate concentration of outlets as a pilot study. The subsequent wastewater will be divided into seven-bath, three-bath containing wastewater and water hyacinth plants with a density different in each basin ie density of 60 mg/cm2, 90 mg/cm2, and 120 mg/cm2, three baths containing hospital wastewater and Azolla plant density of each tub 60 mg/cm2, 90 mg/cm2, 120 mg/cm2, and the control tanks containing wastewater without a given crop. Based on the results obtained, phosphate levels can meet the fastest quality standards for four days on a tub of hospital wastewater and water hyacinth with a density of 120 mg/cm2 and all of a tub of wastewater hospitals and Azolla.
