Abstract

A magnesium oxide and titanium (II) oxide nanocomposite, MgO/TiO2 was synthesized to improve its surface area thus its adsorption capability may be risen. The synthesis was applying sol-gel method, combining MgO and TiO2 nanoparticles with NaOH becomes a nanocomposite with higher surface area. The pH effect on adsorption were analyzed. The expectation of using MgO/TiO2 compared with TiO2 and MgO alone is it may react faster on an adsorption trial with remazol turquoise blue dye, and the TiO2 may give its photocatalysis ability to the synthesized material. Less acid the condition of the solution, the capability of the MgO/TiO2 catalyst on adsorbing the remazol turquoise blue dye will increasing. After 90 minutes, the photocatalysis rate surpass the adsorption rate and reach equilibrium.

Abstract

The rise of clinical activities is one of the health care facilities that have the potential to pollute wastewater on organic compounds and especially pathogenic microorganisms. Technology in reducing organic and pathogenic content using combined ultraviolet filtration in wastewater treatment systems is one the effective method. Filtration uses activated carbon and silica with a variation of the ratio 2:3 and 3:2, while ultraviolet use a power variation of 9 watts and 15 watts. The results obtained are the best composition from the filtration process, which is a ratio of 2: 3 with the ultraviolet process using 15 watts using an exposure time of 5 hours with the remaining total coliform as much as 200 MPN/100mL. The results of this research have complied with the quality standards.

Abstract

A magnesium oxide and titanium (II) oxide nanocomposite, MgO/TiO2 was synthesized to improve its surface area thus its adsorption capability may be risen. The synthesis was applying sol-gel method, combining MgO and TiO2 nanoparticles with NaOH becomes a nanocomposite with higher surface area. Characterization using FTIR were carried out. The expectation of using MgO/TiO2 compared with TiO2 and MgO alone is it may react faster on an adsorption trial with remazol turquoise blue dye, and the TiO2 may give its photocatalysis ability to the synthesized material. The FTIR analysis results show that the MgO and TiO2 are successfully combined become MgO/TiO2 nanocomposite. On adsorbing remazol blue, MgO/TiO2’s surface is chemically influenced by the dye’s C=O and amides group.

Abstract

The local government of Pulang Pisau, Central Kalimantan plans to build a municipal solid waste landfill located in Gohong Village, Kahayan Hilir District. The Gohong landfill is planned to be built with a sanitary landfill system located in Gohong Village, Kahayan Hilir District, Pulang Pisau Regency with an area of 64,260 m2. Based on this, it is necessary to conduct an initial environmental study of the initial environmental components before planning and development begin, to then be managed and monitored during the activity. This study uses two types of data, which are secondary data and primary data. Secondary data includes topographic data and rainfall at the construction site, while the primary data used is groundwater and river quality, and water biota analysis. The results of the study on the development plan for the Gohong landfill show that this area has a medium category of rainfall. The soil types at the site of the development plan are podsol and alluvial soil types. The quality of river water around the planned development site is class 4 water type with good groundwater quality and has diverse biological components with healthy ecosystems.

Abstract

A community service program was held in Surakarta city, in a boarding school named Kanzus Sholawat to solve the cooking oil waste problem. The used oil which locally is alluded to jelantah oil, blackish brown colored, contains exceptionally high levels of cholesterol, carcinogen, and it may cause harm for human wellbeing. Jelantah oil ordinarily will be directly thrown to the environment, hence may cause water and soil contamination. Agreeing to this, it is essential to teach individuals to do minimization and reuse to the utilized oil (jelantah). Besides, the individuals will be prepared to commercialize the items as a souvenir gift item. The jelantah oil will be processed into handwash cleanser products with a feasible, simple, and cheap procedure and utilizing effortlessly obtained material. To start, a 500 ml of used cooking oil is filtered and mixed with 160 grams of NaOH flakes soluted in 200 ml of water. Some drops of fragrance is added to make the soap perfumed. The purpose of this community service is to provide assistance to the Kanzus Sholawat Surakarta Foundation to take the economic value from the oil waste by commercializing the recycle product. The program will be carried out by training and education to handle the jelantah oil into handwash cleanser, and persistent assessment to make sure the Kanzus Sholawat Surakarta students and adjacent community get the optimal benefits. Pre-order sale system using e-commerce is also expected to be implemented by the students, to make this program sustainable.

Abstract

Klotok landfill is a final waste processing site in the City of Kediri that has been operating since 1992 to manage waste in the Kediri City and its surroundings. Waste management activities at the Klotok TPA generate emissions from the waste pile and heavy equipment activities. This study aims to determine the air quality at the Klotok Landfill through direct measurements to obtain results with a more accurate approach. The measurement results will then be modeled with AERMOD software to determine the distribution of these pollutants to the area around the TPA. In this study, air quality measurements were carried out at three points in the Klotok TPA to determine the level of pollution that occurred. Air quality is measured directly using a High Volume Air Sampler (HVAS), Impinger, and Sound Level Meter. Air pollutant parameters measured included Nitrogen Dioxide (NO2), Total Suspended Particulate (TSP), Sulfur Dioxide (SO2), Oxidants (O3), Carbon Monoxide (CO), Lead (Pb), Non-Methane Hydrocarbons (NMHC), Particulate Matter 2.5 (PM2.5), PM10, Ammonia (NH3), and noise. The measurement results show that the CO parameter exceeds theambient air quality standards of PP No. 22 Year 2021 at the weighbridge and the landfill 3 with values of 13,750 and 18,750 µg/Nm3 respectively,while other parameters still meet the quality standard. The model with AERMOD software shows the dispersion of CO nearby the landfill area occurs quickly so that since the first 100 meters the CO concentration has been dispersed to below 10 µg/Nm3. CO concentrations at a distance of more than 1 km from the Klotok TPA are generally below 1 µg/Nm3.
