The rate of population growth which is relatively rapidly increasing in Indonesia, will require increased fuel. The depletion of the availability of fossil fuels causes the search for the other natural resources needed to become a renewable energy source. One of the significant changes today is microalgae. The application of the algal aquaculture system has been widely applied in the world. The media used in cultivation also varies, one of which is wastewater. The composition of biodiesel energy in Indonesia is increasing and is starting to become the people's choice. Indonesia, which is rich in natural resources, especially the high biodiversity of microalgae, causes microalgae's potential use to be very high. Many studies report the explosion of algal participation in many parts of Indonesia. Research concerning the cultivation of microalgae has been widely successful in Indonesia. The use of microalgae is already available in the field with domestic water treatment applications. The conversion of microalgae into biodiesel also successfully met the requirements of SNI 04-7182-2006.

The increasing number of waste-producing industries has led to the emergence of the application of the concept of industrial waste management, including in the heavy equipment rental industry which generates waste in every process of its activity. Not only does it reduce the potential for environmental pollution, this concept can also benefit from a fulfillment of obligations and cost savings. In order to support the achievement of this concept, field studies were carried out to determine the characteristics of the waste produced, as well as literature studies to determine the appropriate measures. After the analysis is carried out, the waste produced is solid waste in the form of used spare parts from the checking and replacement of spare parts, liquid waste in the form of sludge containing detergent, oil and water from the washing process, and CO2 emissions from energy use. Waste minimization is the main effort in industrial waste management and can be achieved by reducing CO2 emissions and applying technology in the form of a gravity separator for wastewater treatment. Processed liquid waste can be reused as clean water so that it can reduce usage and costs for clean water.

Processing of organic waste with biological processes is more economical and effective. Handling biologically organic waste by utilizing microorganisms is a method that is relatively safer compared to chemical and physical methods. Every microorganism in maintaining its survival always carries out metabolism, so it needs additional organic ingredients such as substrate. The study was conducted to determine the effectiveness of substrate addition in the biological treatment of tofu liquid waste using the CSTR system. The COD concentration used in the acclimatization and running process is 1000 mg / L. The process of acclimatization and running used a variation of the ratio of tofu waste: glucose by 25%: 75% and 75%: 25%. The acclimatization and running processes are stopped when the COD removal efficiency is stable. The aerobic process in biological processing was able to set aside COD levels of tofu waste up to 84.62% to produce an effluent with a COD value of 160 mg / L.Keyword: Biological Processing, Substrate, Tofu Liquid Waste

Produced water generated by the oil and gas industry, when treated properly, will produce water that is ready to be reused, such as for watering plants. This planning is done by treating the produced water with Corrugated Plate Interceptor (CPI) and Ultra Filtration units. This research aims to analyze the design details needed in the recycling of produced water with CPI and Ultra Filtration units. After determining the design criteria used, the dimensions for each unit are obtained. Data was collected using secondary data directly from the study site and quantitative method was used for data analysis. The land area for one CPI unit requires 55 m2 with a volume of 110 m3. The Reynolds number and Froude number for CPI units meet the design criteria with 419.8 and 0.24, respectively. The ultra-filtration unit was selected with a Flux specification of 0.15 m3/m2.hour with an operational duration of 24 hours. The results of processing with the CPI unit can at least produce oil and fat effluent of 0.038 mg/L, with the threshold for water quality is 1 mg/L. Produced water treatment planning with CPI configuration and UF membrane with storage tank requires a total land area of 63.97 m2..

The cement industry is one type of industry that has implications for the emergence of environmental pollution problems and a decrease in environmental quality due to dust pollution. The cement industry can also increase air temperature and noise in operational activities by using machines. In addition, the impact of the cement industry is the decline in the quality of soil fertility due to clay mining. Thus, an analytical study is needed that can be used as one of the policy bases in the operational process of the cement industry. This study aims to conduct an analysis of environmental loads at each stage in the product life cycle, make decisions to identify environmental loads, and evaluate the environmental impact of a product that plays an important role in sustainable development. This method is known as Life Cycle Assessment (LCA). In this study, the boundary system used is cradle to gate with a three-scenario approach. The first uses 100% coal fuel, the second uses 90% coal fuel, and the third uses 10% rice husk biomass. Then the analysis was carried out using the OpenLCA software. The results of the analysis showed that the most significant emission load was carbon dioxide of 1229.31 kg CO2eq. The third scenario produces the lowest carbon dioxide emission load compared to other methods of 849.1 kg.
