Abstract

The Kappaphycus alvareziiseaweed in Pulau Panggang, Kepulauan Seribu, DKI Jakarta, has experienced a significant decline in production. From 1984 to 2000, production ranged from 8,106 to 36,625 tons, contributing 25.61% to the total production in the Thousand Islands. However, in 2021, production drastically decreased, reaching only 254 tons in 2019. This study focuses on identifying the factors causing the decline in production. Analysis of water samples indicates that oil and fat pollution in the aquatic environment exceeds the established standards, surpassing 1 mg/L, potentially harming marine life, including seaweed. Field observations reveal the fact that the seaweed's ability to survive is within a specific timeframe (seaweed lifespan) that never reaches the harvesting age due to consistent occurrences of death. SEM-PLS analysis shows that both physical and chemical parameters influence the seaweed lifespan by 43.9%. Statistical analysis supports the hypothesis that physical parameters are not significant(p>0.05), while chemical parameters, indicating oil and fat pollution, significantly affect seaweed lifespan(p<0.05). This research provides profound insights into the causes of the decline in Kappaphycus alvarezii seaweed production in Pulau Panggang.

Abstract

Whitening cream is a mixture of chemicals or other ingredients with the property of being able to whiten the skin or lighten black spots on the skin. Facial whitening creams contain harmful compounds such as mercury and hydroquinone. Mercury is a dangerousheavy metal that is toxic and carcinogenic to the body, while hydroquinone is a chemical compound that is included in hard drugs and used by doctors as a drug to treat hyperpigmentation. The purpose of this study was to determine the presence or absence of mercury and hydroquinone in the samples and to determine the levels of mercury and hydroquinone in face whitening creams circulating in Aceh Market. The stages of this research consisted of testing the mercury content using KI 0.5 N, determining the levels using an Atomic Absorption Spectrophotometer, testing the hydroquinone content using 1% FeCl reagent and determining the hydroquinone content using a UV-Vis spectrophotometer. The results of the research showed that of the 8 samples studied there were 4samples containing mercury, namely with levels in sample code B (5.729,20 mg/kg), C (5.692mg/kg),D (2.905mg/kg), E (104,83 mg/kg) and the 8 samples studied there were 6 samples containing hydroquinone, namely the levels in sample B (6,239ppm),C (6,890ppm),D (6,478ppm); E (10,637ppm),G (7,722ppm),H (3,638ppm).

Abstract

Rancasari Subdistrict is locatedin Bandung City,comprisesfour urban villages, encompassing 0,19 km2with six blocks of light slum areas. Slum areas are areas that tend to have more vulnerable environmental conditions due to the minimal availability of environmental infrastructure, one of which is sanitation facilities. Based on this, Rancasari subdistrict needs to determine the type of domestic wastewater management system service and priority service areas. Determination of the service type of domestic wastewater management system is determined based on Attachment 1 ofRegulation of the Minister of Public Works and Public Housing Number 4of 2017, while priority areas are determined based on Bandung City Regional Regulation Number 5 of 2022, Regional Regulations Bandung City Number 10 of 2015, and the area of slum settlements in each village. Rancasari Subdistrict is suitable foron-site system, while the main priority area is Manjahlega Village, then Mekarjaya, Derwati, and Cipamokolan.Itisnecessary to develop domestic wastewater management system facilities in the mainpriority area in the form of development of existing communal septic tanks and communal wastewater treatment facility, as well as the closure of piped domestic wastewater disposal facilityleading to the Cidurian River to stop open defecation

Abstract

The Riau Islands Province in Indonesia was among the regions impacted by the pandemic, which also influenced electricity usage patterns and subsequently, the environmental impact. To assess these environmental impacts, life cycle assessment (LCA) is an effective tool. This research aimed to evaluate the environmental implications both before and during the COVID-19 pandemic, using SimaPro v.9.1.1.7 software and the Environmental Product Declaration (EPD) database for impact analysis. The inventory data showed that in urban areas like Batam City and Tanjung Pinang City, as well as in Bintan Regency, there was a notable decrease in electricity consumption between 2019 and 2020. Electricity is a crucial energy resource for communities, and this was particularly evident during the COVID-19 pandemic. The Riau Islands Province in Indonesia was among the regions impacted by the pandemic, which also influenced electricity usage patterns and subsequently, the environmental impact. The inventory data showed that in urban areas like Batam City and Tanjung Pinang City, as well as in Bintan Regency, there was a notable decrease in electricity consumption between 2019 and 2020. This reduction led to a significant overall decrease in environmental impact. However, it's important to note that this reduction, brought on by the unpredictable nature of the pandemic, may not be sustainable in the long term.

Abstract

The issue of the spread of marine debris or &quot; marine litter&quot; is in the global spotlight due to its detrimental impact on ecosystems, humans and marine life. The focus of this research is on the coastal area of Kuta Bali, Indonesia, with the main objective of identifying the factors driving damage to marine ecosystems due to plastic waste. Using the DPSIR (Driving Force, Pressure, State, Impact and Response) method approach, this research analyzes the causes and effects related to this environmental problem, highlighting the pressure generated by marine plastic debris, describing the conditions in coastal areas and evaluating the impacts that arise. The results show that the coastal area of Kuta Beach, Bali, is facing serious challenges related to marine plastic waste that is destroying the environment around Badung Regency. As a prevention and control effort, it is recommended that education and training exist in each coastal area, aimed at increasing public awareness of waste management and the potential dangers of marine plastic waste to the environment, in the hope of creating a safer environment and sustainable coastal environment.

Abstract

Domestic liquid waste typically originates from home trash and requires treatment to decrease quantities of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), and mixed particles. Additionally, treatment is necessary to eliminate nutrients and harmful components. The objective of this study is to determine the optimal dosage of biocoagulant needed for the process of coagulation and flocculation in a laboratory setting using the jar test method, specifically for treating domestic wastewater. Tamarind seed shell waste contains tannin, which can act as a natural coagulant. It functions as a positively charged natural polyelectrolyte that efficiently binds to negatively charged colloidal particles. The study included independent variables consisting of different doses of a mixture between tamarind seed shell and sweet orange peel bio coagulants, with ratios of 1:0, 1:0.5, and 1:1. An optimal dosage of 1.5 grams of tamarind seed shell effectively reduced turbidity by 51%, BOD levels by 80%, and COD levels by 77%.

Abstract

Work posture plays a crucial role in productivity, and improper postures can lead to ergonomic issues, particularly muscle injuries in workers. The downstream polymer automotive industry, particularly in the production of automotive components using plastic injection processes, often involves workers in various work postures, increasing the risk of muscle injuries. Non-ergonomic work postures can result in muscle tension and health problems, emphasizing the need for a focus on safety and ergonomics in the work environment. This study employed the Ovako Working Posture Assessment System (OWAS) and Rapid Entire Body Assessment (REBA) methods to analyze work postures in the automotive industry. Research recommendations include the necessity for ergonomic control efforts to reduce the impact of muscle injuries due to suboptimal work postures. These ergonomic measures are expected to decrease injury risks, enhance productivity, and contribute to the safety and well-being of workers in the automotive industry. The study provides a foundation for companies to improve efficiency, work quality, and safety conditions in the future.
