Abstract

Food sanitation is one of the methods used to protect food from contamination, maintain quality, and prevent potential bacterial transmission. This research was conducted to observe potential diseases caused by the microbiological quality of clean water for household use. MPN method was used to compare the quality of clean water based on the Peraturan Menteri Kesehatan Nomor 416 Tahun 1990. Swab method was implemented to observe the hygiene level of the cutlery to compare with the Peraturan Menteri Kesehatan Nomor 1098 Tahun 2003. 79/100 ml of total coliform found in tenant 1 and tenant 2 which means it did not meet the standards. Escherichia coli were found absent in both clean water sources. The same result comes from 2 samples of plates and spoons before and after the first usage and second usage. In tenant 2, Escherichia coli were found in plate sample no.1 before usage and the clerk’s hands before serving the food. Hence, it did not meet the standards. Based on the interviews and observations, the sanitation hygiene of the clerks and the physical hygiene of tenant 1 and tenant 2 had only fulfilled 61.9% and 57.1% of proper hygiene, so it needed to be improved.

Abstract

Air pollution is one of the environmental problems that can have serious impacts on humans and the environment. To prevent these negative impacts from spreading, environmental monitoring efforts can be carried out periodically. The existing monitoring methods basically use chemical methods that are destructive. Therefore, the development and use of fast and non-destructive methods is a much-needed innovation. One of the alternative methods that are expected to be such an innovation is the rock magnetization method. Magnetic rocks have been used to assess climate and environmental changes. The application of this method has been used in the field of biomagnetism or the study of magnetism in living things through the presence of magnetic minerals based on the type, grain size, grain shape, and morphology. This article is an overview of the use of rock magnetization methods to characterize leaves as receptors for atmospheric pollutants.

Abstract

Surfactants are compounds that make up deterjents, which if deterjent is dumped into the river it will cause pollution. In the province of West Java, river water and receiving water bodies, based on the results of the study, showed moderate to severe pollution by wastewater containing deterjents. The results showed that the PAC coagulant and alum has a small effect on the decrease in surfactant and floc velocity settling, where the decrease in surfactant in the rainy season for PAC coagulant is 49.51% and alum coagulant 40.73%. While in the dry season the decrease in surfactant with PAC coagulant 41.06% and alum coagulant 31.10%. Then the floc velocity settling was measured to explain the correlation of surfactant decline, and the results obtained for the rainy season floc velocity settling with PAC coagulant was 0.80 cm / minute and alum was 0.27 cm / minute. Whereas in the dry season with the PAC coagulant the floc velocity settling was 0.91 cm / minute and the alum coagulant was 0.31 cm / minute. The results of quantitative regression analysis with the SPSS statistical test showed that the H0 hypothesis was accepted, that the coagulant had no effect on surfactant reduction and floc velocity settling.

Abstract

Technological developments that increase the increase in electronic waste (e-waste) significantly. In Indonesia, the method of treating electronic waste by fire is not appropriate to apply, because electronic waste contains metals and will cause dangerous air pollution (for example: lead pollution). Electronic waste processing is different from organic waste that can be processed into fertilizer. Therefore, this condition can be categorized as an important problem, so it requires smart solutions that are fast and precise in processing. Handling this waste can be solved through several methods, namely e-waste banks and art integration. This method prioritizes artistic value, creativity, function, and in-depth knowledge of the waste, so that it can also take advantage of organizations or businesses that will bring profit and be environmentally friendly. This has also received support from the government through a program commonly known as Small and Medium Enterprises (UKM). The components that are usually buried, melted down, and destroyed will be sorted again based on their physicality so that it will facilitate the process of making art.

Abstract

This study aims to identify and evaluate the management of toxic and hazardous materials (THM) at Universitas Padjadjaran (Unpad) Dental Hospital. This hospital is a special teaching hospital to support the teaching and learning process at the Faculty of Medicine Unpad. Based on the results of observations, THM were produced as much as 322.96 kg/month. The waste generation includes infectious, sharp objects and pharmaceutical waste. The research was conducted by using a comparison method between the conditions at the research location and the applicable regulations. Based on the results of research, the Dental and Oral Hospital Unpad has carried out the management of THM in accordance with applicable regulations. There are several aspects that must be improved, namely the process of sorting and packaging of THM, and attaching symbols and labels to containers. Temporary shelters for THM are operating properly according to the criteria, but there are several things that need to be improved, namely routinely replacing damaged labels because they can cause misinformation about these THM. Shelters need to be equipped with cooling devices, improve ventilation, and establish good trench drainage while THM increasing.

Abstract

Anchovies are a group of pelagic fish that inhabit coastal waters and have a very wide distribution. In Indonesia, this species of fish are also preserved through the drying process. The humidity of the drying room must meet the humidity requirements required for drying of 55 - 60%. The natural drying process takes 8 hours of drying time per day for 3 days in areas with high sunshine intensity. Drying work must be accompanied by turning 2-3 times every day. The fish drying technology that has been completed is capable of drying fish for one hour with a capacity of 15 kilograms, and requires a supply of electricity of 3065.5 watts from the state electricity company. The high consumption of electric power required will affect the value of the production costs required so that it is necessary for this analysis to obtain an initial model of the location, type, number of turbines - solar panels, and batteries used to operate the fish dryer. The estimation result of the average daily electric power generated from wind speed is 389,53 watts hour (Wh) and solar energy is 5,79 watt hour. The total potential of electric power generated on period August - September 2020 is 2,31 kilo-watt hour (kWh).
