Abstract

One of the causes of congestion on the highway is the increasing number of motorized vehicle users, whose percentage is now increasing from the use of other vehicles or transportation. Every vehicle in circulation also comes from companies and with various brands. This study aims to determine the comparison of emissions or pressure produced at three constant speeds by five motorized vehicles with different brands using the same type of fuel, to determine the amount of emissions released by each vehicle brand and every hour, and the impact of the resulting emissions on environmental health. . The research was conducted using a quantitative descriptive method with a sampling technique and the data were then analyzed with a literature review and information obtained from the STNK. From this research, it is found that different motorcycle brands with the same year of production have different emission results. Of the five types of brands tested, motorized vehicles with the Beat 110 CC brand and the year of engine production being longer than the other four types produced fewer gas emissions, namely 3237 at a speed of 60 KM/hour. In addition, the pressure (ppm) on the Beat brand will also be lower, although the speed that is different from the other four brands will actually increase the pressure. For the value of emissions issued per hour will also be in line with pressure (ppm). Gas emissions released by motorized vehicles themselves have a harmful impact on health and the environment. One of the dangers posed by vehicle exhaust gases for health and the environment is the increase in hemoglobin levels in the blood which will form COHb in the body. Keywords: CO Gas, Emissions, Motorcycles.

Abstract

River water quality is influenced by the natural conditions of the river, human activities and land use in the vicinity. Water pollution is the inclusion or entry of various kinds of objects, living things, energy, substances and other components into the air by human activities, which then causes air quality to decrease to a certain level so that it cannot be utilized according to its use. Pepe River is one of the rivers that pass through the Surakarta area. Pepe River is divided into two, namely Pepe Hulu and Pepe Hilir. The Pepe Hilir River is 5.76 km long. Pollution that occurs in the Pepe River is dominated by household waste. The water quality of the Pepe Hilir River is classified as class IV. This study aims to determine the pollution of the Pepe Hilir River so that it can provide recommendations for water management strategies for the Pepe Hilir River. This study uses descriptive quantitative methods obtained through observation and journal literature related to physico-chemical parameters in river water. The results showed that the level of water pollution of the Pepe Hilir River was said to be good at the three research locations, not showing any water pollution based on the results of measurements using HORIBA U-50 (Multiparameter Water Quality Checker). Based on secondary data in the form of previous research, it shows that the Surakarta City government has promoted the Pepe River pollution control strategy, but community participation is still considered minimal. Therefore, the recommendation for the government is that the government prioritizes the community so that they are able to contribute to waste management on the banks of the Pepe River with outreach campaigns to villages traversed by the Pepe Hilir River. The government can also understand with community leaders or community institutions to help encourage the community to want to participate in river management programs. In addition, the Surakarta city government is also advised to provide great opportunities for the community to be involved in programs promoted by the government.

Abstract

Contamination of leachate due to excessive rainwater infiltration into landfill sites presents a significant environmental and public health concern. This study aims to address the adverse impacts of cadmium (Cd) pollution in leachate, specifically its risks to human health and the environment. To address this issue, the research investigates the use of natural adsorbents to mitigate agricultural waste. Straw and cassava peel, abundantly available in Indonesia due to the country's substantial rice and cassava production, were selected as potential adsorbents. The findings of this study are important for guiding pollution control measures and evaluating community activities near pollution sources, particularly focusing on Cd pollution originating from Putri Cempo in Jatirejo Village, Mojosongo, Jebres, Surakarta. The research shows that cassava peel waste is highly effective in adsorbing cadmium metal levels in leachate, with a significant total effectiveness (EF%) rating of 0.3144. Additionally, the study identifies the optimal burning temperature for activated charcoal derived from cassava peel as 600°C, resulting in the highest EF% value of 0.515152.

Abstract

Noise can cause nuisance and significantly threaten people's health and well-being. This study aims to find the relationship between noise exposure with blood pressure and stress of traffic helper volunteers in Makassar City.  This study employed an analytic observational design with a cross-sectional approach. A total of 80 respondents were selected using purposive sampling technique. Traffic noise was measured using a sound level meter, blood pressure was measured using a tension meter and work stress was measured using a work stress questionnaire adapted from Permenaker No. 5/2018. Questions relating to sociodemographic information were also distributed for individual characteristic data. The results showed there was a significant influence between noise intensity and systolic blood pressure (p value = 0.001; r = 0.329), also with diastolic blood pressure (p value = 0.02; r = 0.230), noise also affects fatigue (p value = 0.016; r = 0.238), the value of r on the strength of the correlation shows a fairly strong correlation. Thus, exposure to traffic noise is associated with a high risk of blood pressure and fatigue.
