Abstract

Semen Z is one of the largest cement supplier companies in Indonesia and will continue to increase every year. The development of the cement industry is in line with the continued development of infrastructure projects, both private and Indonesian government. PT. Semen Z has good integration from raw material providers to cement that is ready to be used by every project that requires it. Development of PT. Cement Z will occur in the quantity of raw materials, human resources, and production processes, up to distribution to consumers. The activities carried out are land clearing/stripping, blasting, excavation and loading, as well as transportation and destruction. Raw materials sourced from this mining process include limestone, silica stone and clay. In this study mining was only carried out on limestone and clay was obtained from suppliers. The units used in the inventory data are limestone and clay raw materials (tons), ammonium nitrate chemicals (tons), diesel fuel (liters), electricity (kWh), emissions (tons), B3 waste (tons), non-B3 waste (tons) and products (tons). Every activity process carried out will have an impact on the environment, so the Company's commitment to a green industry or clean industry is required. To determine the environmental impact analysis on cement production activities, the Company conducted an environmental impact analysis using the Life Cycle Assessment (LCA) method. The aim of this research is to identify improvements in environmental performance, especially those that are hotspots in the Company's production process. The research results show that the highest identification of environmental impacts is obtained from activities at the Limestone mine, in accordance with the Pareto rules approach where if the contributors are more than 80% of the food it will affect the results of the impact analysis obtained.

Abstract

The problem of domestic wastewater originating from restaurants is the largest contributor to organic wastewater in urban waters. Among them are waste water parameters, namely oil, and grease. Oils and grease are compounds that do not dissolve easily in water. However, it can be dissolved with non-polar organic solvents. The carbon chains of oils and grease are also long. So, it is difficult to decompose and takes a long time if processing uses the help of microorganisms. So, the alternative is to use physical-chemical processing. In this research, we tried using a static mixer and an impeller mixer. We conducted a systematic review of DAF techniques in wastewater treatment. We reviewed six indexed databases namely dissolved air flotation, microbubbles, wastewater treatment, and key operational and design parameters involved in the effectiveness of the flotation process. In this pre-treatment, the focus is on the withdrawal/discharge speed in collecting wastewater as a test and the effectiveness of mixing wastewater with coagulants and air pressure. These three aspects are used in equilibrium to achieve the optimum dose for the static mixer use scheme. Meanwhile, the impeller mixer scheme uses rotational speed in mixing with the coagulant, contact time, and Reynolds number to achieve the required turbulence. Apart from that, the use of electrical energy in the pump is also calculated in these two schemes. The results obtained were the amount of weight of oil and grease collected in the static mixer pretreatment of 9.12% w/v and the impeller mixer of 7.63% w/v and the results of the organic content of the Chemical Oxygen Demand (COD) parameter for the static mixer were 86.92 % and mixer impeller 78.86 %. From these results, static mixers have advantages over using impeller mixers in terms of the effectiveness of the oil and grease reduction process.

Abstract

Universitas Pembangunan Nasional (UPN) "Veteran" Jawa Timur is one of the state universities located in the Rungkut Madya-Gunung Anyar area, Surabaya, where various activities take place daily. Based on the types of activities, the sources of waste at UPN "Veteran" Jawa Timur are divided into two areas: waste from academic buildings, offices, and cafeterias, and waste from gardens and streets. About 70% of the waste generated by campus activities has the potential for recovery. Organic waste from garden sweeping, cafeterias, and other activities can be processed through composting. In addition to composting, there is currently another alternative method with better economic potential, one of which is turning it into eco-enzymes. Commercialization is understood as a process of developing new products from creative industries, making a product more valuable and commercially viable. In this article, commercialization is also understood as a comprehensive technology transfer process, starting from selecting raw materials for a product and continuing through the production process until the product is produced and reaches the end consumer. With the available and applicable processing technologies, it is hoped that this commercialization activity can assist in promoting the transformation of waste into furniture, home décor, and eco-enzymes by business groups. It includes designing commercial packaging for products and creating management and promotion schemes for processed campus waste products at UPN "Veteran" Jawa Timur.
