Abstract

The need for water in an area is certainly different. Water needs in rural and urban areas are clearly different. This difference in water demand is influenced by water usage, and this difference in water usage will give rise to the value of water fluctuations. This study aims to determine the value of water usage fluctuations in rural residential areas so that water suppliers can know the exact amount of water discharge that will be distributed to customers in the area, in this way it is expected to make the water distribution system more effective, then it is also expected that the water supplier is able to know the number of water losses distributed to make improvements to the network system in the residential area. This research study is located in a residential area of the village, with a research time of 24 hours. From the results of observations in the field which were then calculated, the total debit of water usage per day from a total of 632 customers in the area was 320 m3 / day or 3.70 liters / second. As for the secondary data obtained, the total water distribution to customers in the village settlement area is 5169 m3 / month or 1.99 liters / second for the period April 2023.

Abstract

Transportation plays a role in human life. One of the transportation activities is moving goods from one place to another. Transportation can support human activities to be faster and easier. Examples of transportation activities are motor vehicles, cars, conveyors, and the like. The results of these activities produce waste, one of which is liquid waste in the form of liquid and usually this type of liquid waste is very risky to pollute the environment. For one industry, liquid waste generally consists of solid waste materials, organic waste materials and inorganic waste materials left over from production, while household/domestic waste can be in the form of dirty water from bathing, washing and toilet use. The research objective is to determine environmental compliance by conducting Indirect Supervision of the Transportation Industry in the City of Madiun, East Java, namely the Waste Quality Standards, the parameters used and the Standard Quality Standard Regulations used. This study used a quantitative-descriptive research methodology, namely research that only describes the contents of a variable in the study, not intended to test a particular hypothesis. Then from the results of the Evaluation of the East Java Province Environmental Service for the Transportation Industry it has compliance status by conducting a Wastewater Sample Test to a Laboratory that has a National Accreditation Committee (KAN) and is checked regularly once a month by fulfilling the Quality Standards in accordance with: Regulations Minister of Environment and Forestry of the Republic of Indonesia Number P.68/Menlhk/Setjen/Kum.1/8/2016 Concerning Domestic Waste Quality Standards

Abstract

The operation of the fertilizer industry can cause environmental pollution, so that preventive or preventive measures are needed aimed at controlling the remaining air emissions produced and creating alternative ways of production that are environmentally friendly. In this study, the environmental impact is determined using the life cycle assessment (LCA) method, on the products and emissions produced as well as the materials used, such as raw materials, chemicals and fuels. Environmental impact assessments were carried out using an endpoint approach using the 2016 recipe method and divided into three main categories including human health, ecosystem quality and resources. In this study, SimaPro 9.4.0.2 and Open LCA 1.11.0 software are used to determine the extent of the environmental impact of the LCA process. In the LCA results, the most important moisture category in the entire ZA II fertilizer production process is resource impact with the “lost fossil” impact category, while the process unit that produces the highest impact value is drying and cooling. The effects seen in this unit are due to the presence of ammonia chemicals from dirt-repellent materials, the resulting ammonia and carbon dioxide emissions, and excessive electricity consumption. Therefore, it is necessary to provide alternative recommended repair programs. Alternative programs that can be used to minimize the impact include: reducing anti-caking doses, using transformers, and combining reducing anti-caking doses & using transformers.

Abstract

This study was conducted to determine the effect of height in the calculation of box model dispersion modeling. The experimental method was conducted using sample data of sulfur dioxide exhaust emissions produced by the oil and gas industry. The samples were obtained from an oil and gas company that produces sulfur dioxide emissions. There are two types of data obtained, namely hourly emission data and daily emission data generated by the industry with the amount of data obtained for 360 days. The results showed that the mixing height used in the box model formulation affects the results of the calculation. The optimal mixing height obtained from the study was 75 meters where all sample data used in the calculation showed that there were only 3.5% or 11 samples that did not meet the ambient air quality standards. The results also showed that the higher the mixing height used, the lower the emission of sulfur dioxide emission dispersion modeling calculation results. While calculations with lower mixing height will produce results that are inversely proportional to the concentration of sulfur dioxide emissions, the concentration of sulfur dioxide emissions produced will be higher. Therefore, sulfur dioxide dispersion modeling using a box model can be an alternative in determining the concentration of sulfur dioxide emissions produced.

Abstract

Violces (Viola odorata) is an herbal plant from the Violaceae family and is used in traditional medicine. This is believed to be due to the presence of phytochemical compounds in the Violces plant that provide the pharmacological activity. This study aims to determine the extract yield value and chemical compound groups contained in Violces leaves. The research method consists of four stages, namely extraction, evaporation, yield value calculation, and phytochemical screening. Violces leaf extract was obtained by maceration for 3 days using methanol as the solvent, then filtered and concentrated using a rotary evaporator. The concentrated extract of Violces leaves was then used to calculate the yield value and subjected to phytochemical screening for alkaloids, flavonoids, tannins, saponins, steroids and terpenoids. The method used for the identification of secondary metabolite compounds involve the use of chemical reagents, indicated by color changes, precipitate formation, foam/bubbles, and rings. The results of the study showed a methanol extract yield of Violces leaves of 26,70%. The phytochemical screening test of the methanol extract of Violces leaves revealed the presence of tannins, saponins and steroids.
