Abstract

Water is the main need for humans, so the quality and quantity must be maintained. The purpose of this research is to analyze the problems in Joho Village in the form of cloudy water so that the community feels disturbed. In this study, the water quality test was carried out using the Indonesian National Standard and with a random sampling technique. Samples were taken from 3 points in residents' houses and 2 points in public facilities, namely in parks and places of worship. Data analysis was carried out by descriptive quantitative. There is one sample that does not meet the quality standard for odor parameters, namely at the observation point in the park. However, for the turbidity parameter, all samples showed that none met the quality standards, namely 116, 48, 100, 136, 130 NTU. The solution that can be done by residents of Joho Village is to do pavement and closure in the area around the shallow well and perform simple filtration consisting of Zeolite (10 - 30 mm), Zeolite (5 - 10 mm), Silica sand (4 - 30 mesh), Activated Carbon, and Sponge.

Abstract

In the era of the COVID-19 Pandemic, medical waste is increasing in various hospitals, including UNS Hospital. The variables studied in the hazardous and toxic solid medical waste flow treatment. Primary data was obtained from an analysis of waste amount in 2021 and interviews with incinerator managers. Secondary data in the form of waste types, impacts, and incinerator residue were obtained from the literature study. This research aims to identify solid medical waste management with hazardous and toxic materials compared with Regulation of Environment and Forestry Minister of Republic Indonesia 56/2015. After analysis, it was found that there is dangerous and harmful solid medical waste flow management, distinguished by type. Particular colored medical waste is managed by reducing, sorting, storing, transporting, and destroying. Destruction is conducted with an incinerator. Arah Environmental Indonesia Company operates infectious medical waste. The potential impact of that waste can attack health, damage the environment quality, increase the degradation that has occurred, and pose a threat to microplastic. Completing waste management is done by tightening hospital regulations to produce output according to quality standards, limiting hazardous and toxic waste use, and selecting the waste.

Abstract

This study uses the pollutant index method to determine the form of river utilization by the surrounding community and the level of river water pollution. The research method used in this study is qualitative and quantitative analysis. Qualitative descriptive analysis method is used to analyze the form of river utilization by the community. Analysis of river water quality used quantitative method which refers to the Decree of the Minister of Environment 115/2003 concerning Determination of Water Quality Status using the Pollution Index (PI) method. The results of the analysis show that the community uses the Pepe River as a source of water and rainwater storage, waste disposal sites, fishing grounds, drainage channels, and agricultural irrigation. So that it has the potential to experience water pollution due to the entry of domestic-industrial waste. Based on PI, the flow of the Pepe River is proven to be lightly polluted, with the results of several parameter measurements showing results above the quality standard. Therefore, one of the recommendations that can be applied to overcome these problems is to develop the concept of Community-Based Development by involving the active role of all society levels in planning and implementing river management and development activities.

Abstract

Vegetation is an important component in an ecosystem. Padalarang Sub-District is a sub-district in West Bandung Regency with the smallest area but the most densely populated among other sub-districts in West Bandung, with a density of 3,478 people km2. The purpose of this research is to analyze the level of vegetation density using the Normalized Difference Vegetation Index (NDVI) technique as a consideration, especially for the government regarding development program arrangements. The method used was Landsat 8 image interpretation with NDVI, and the results will be classified according to the classification of vegetation density used. As a result, the density of vegetation has decreased from 2013 to 2021, area of non-vegetation and sparse vegetation land indicates, increasing by 5.3% and 4.51%, respectively. In the classification of fairly dense, dense, and very dense vegetation, density decreased by 4.39%, 4.86%, and 0.55%, respectively, which has resulted in reduced green areas becoming built-up areas along with the development of the number and mobility of the population. It is necessary to increase the amount of vegetation and stipulate development regulations that take into account the existence of vegetation as a support for ecological functions.

Abstract

The Sekar Lepen Keprabon River is one of the tributaries polluted by domestic waste. This study aims to determine the water quality of the Sekar Lepen Keprabon River before and after filtering using SPZ (coconut fiber, banana fronds, zeolite stone) and SPA (coconut fiber, banana fronds, coconut shell charcoal) filter media. This experiment uses SPZ and SPA filter media to purify water that is applied directly to the river. The methods used were primary and secondary data collection. The data obtained were analyzed using a descriptive quantitative approach and the effectiveness of each parameter was calculated. The results of this study indicate that the water quality before and after filtering with SPZ filter media obtained a fixed temperature value, pH increased, COD and TSS increased, and TDS decreased. Water quality before and after going through the SPA filter media obtained a fixed value in temperature, pH increased, COD and TSS decreased, and TDS increased. SPZ filter media in the water filtration process is more effective in increasing pH parameters and reducing TDS parameters in river water. In contrast, SPA filter media in the water filtration process is more effective in reducing COD and TSS parameters in river water.

Abstract

Plastic waste is a substance that is no longer used and contains certain elastic materials that require heat energy to decompose. Plastic waste has a longer time to decompose, which is about 20 to 100 years. The purpose of this study is to identify public perception and participation in plastic waste management, analyze the relationship between internal and external factors and perceptions of plastic waste management, and analyze the relationship between public perception and participation in plastic waste management. The research was conducted through explanatory research with a cross-sectional design. The population in this study is the people of Kelapa Island, Seribu Islands, DKI Jakarta with a sample of 300 respondents. The results showed that there was a relationship between knowledge (p-value = 0.001) and the role of government/community leaders (p-value = 0.002) with perceptions of plastic waste management. There is a relationship between public perception and participation in plastic waste management (p-value = 0.000). The conclusion shows that the perception of the community as a whole is positive and community participation in the management of plastic waste is already high. It is hoped that the programs that have been successfully implemented need to be maintained, improved, and monitored regularly.

Abstract

In recent years, the Central Java Province municipal river's water quality in the area is classified as heavily polluted. Therefore, research on water quality and its pollution level needs to be carried out in the Surakarta municipal river, especially in the Central Java Province. This study aimed to determine water quality and the pollution conditions in the Surakarta municipal river and analyze the conditions of the pollution load in the river at a predetermined observation point. This research was conducted using a survey method field with secondary data. The analysis was carried out using the method water quality index (WQI). The results showed The WQI change from heavily polluted to lightly polluted was measured at several observation locations from 2016 to 2018. The changes in the measured pollution index from 2016 to 2018 by coliform.
