Abstract

Water cleanliness plays an important role as a parameter in observing the quality of water that is suitable for consumption for every human life. This is certainly reflected in the health of a healthier life, but so far it is still low in the water quality that is suitable for community use. This study presents a simple technology to design water filtration using an up-flow system (bottom to up) and finds the effectiveness of the filtration media in reducing the content of iron (Fe) and manganese (Mn) metals in groundwater. Water samples were taken from Bukit Fadiah Asri Housing, Kendari City, and tested using three variations of media composition consisting of fiber, gravel, activated charcoal, black sand, and silica which flowed from bottom to top by gravity. Based on these results indicate that type B media material consisting of gravel, palm fiber, black sand, activated charcoal, silica, and palm fiber with a media thickness of 10 cm has a very good level of effectiveness which can reduce the metal content of Fe by 75% and Mn by 66%. This simple and inexpensive filtration media can be applied to the community to neutralize groundwater turbidity and reduce Fe and Mn metal content because it is used as an adsorption medium for heavy metals in water.

Abstract

Listed as one of the largest waste contributor provinces in Indonesia. The population of East Java in 2020 reached 39 million people, it is the second highest in Indonesia. The increasing number of people accompanied by an increase in income will increase people's consumption in an area and this will cause the increasing amount of waste. If this waste problem is not handled properly, it will have a domino effect as well as degrading the environment. This study wanted to determine the effect of population, real expenditure per capita per year and the number of waste banks on the amount of waste in 2020 in East Java Province. This study uses a comparison of OLS Regression and Robust Regression models. The criteria for selecting the best model use the smallest MAPE, RMSE, and RSE values and the largest R-square value. The results of the partial test and the simultaneous test show that the variables of population, real expenditure per capita per year and the number of waste banks significantly affect the variable amount of waste in East Java with the selected model is the Robust Regression model. The R-square value of the Robust Regression model in this study is 0.8909, meaning that the model's ability to explain the variability of the East Java waste amount data is 89.09 percent, and the rest is explained by other variables not included in the model.

Abstract

Development of cities increasing rapidly and low of green open space cause availability of soil surface for water infiltration decreasing. In Contrast, the water runoff in hight affects the puddles like in UIN Sunan Ampel Surabaya Campus in rainy season, especially after heavy rain. The aim of study is to know how many hight of puddles in drainage channel with low of gradient hydraulic value and to know soil ability in site to infiltrate water. Many tests of laboratory were conducted such as: properties soil test, permeability, and infiltration test to analysis the biodrain need in 5 (five) of drainage channel. The result show that channel C-D needs 16 biodrain, channel K-M needs 5 biodrain, channel M1-M dan P1-Q1 needs 12 biodrain, Moreover, channel Q-T needs 30 biodrain to infiltrate water to soil effectively. Keywords: Bioporedrainage, water infiltration, Runoff.

Abstract

Sanitation is the most important health-related aspect of public health and the environment. Aspects of environmental health in sanitation include community clean water facilities, waste management, waste management, and management of sanitation facilities. Islamic boarding schools are one of the institutions that have problems in sanitation, cases are often found related to students who are infected with several diseases. This study aims to map the sanitation conditions and the risk of disease in Islamic boarding schools in the city of Surabaya. This study uses the observation method for data collection, then analyzed by quantitative description. The sanitation conditions of Islamic boarding schools in Surabaya City from the aspect of clean water are in a good category 55.2%, 41.4% very good, and 3.4% less. Based on the waste aspect, the category result sufficient, less, good, and very good is 52%,  24%, 17%, and 7%, respectively. Furthermore, based on aspects of toilet and bathroom hygiene, the majority was very good, 82.8%, sufficient category was 13.8%, and the good category was 3.4%; and based on wastewater aspects, 100% Islamic boarding school was a very good category. In conclusion, the sanitation conditions of Islamic boarding schools in Surabaya City based on the waste aspect are sufficient; however, based on clean water, the hygiene aspects of toilets and bathrooms, and the aspect of wastewater are very good.

Abstract

Leachate is a secondary product from piles of waste that decomposition of microorganism. Ngipik landfill is a landfill with an open dumping waste management system. This causes the soil and ground water to be suspected of being polluted due to landfill leachate. For this reason, it is necessary to identify the pattern of distribution and pollution of landfill leachate in order to determine how far the landfill leachate moves. This research uses the analytical solution method of Ogata-Banks and Domenico-Robbins to build a model for the distribution of contaminants in groundwater. The model was formed using MATLAB with COD and BOD parameters. The model data is validated with field data obtained from wells around the landfill. The results of measuring the quality of 3 wells are 29.8-31.8 0C, pH 5.7-6.4, DO 4.6-8 mg/L, COD 36.5-140.5 mg/L , and BOD 12.1-40.35 mg/L. The model simulation shows that COD and BOD are not detected at a distance of ± 278 m and ± 401 m. The validation results of the two models show that the Domenico-Robbins model has an error of 0.0016 for COD and 00.000467 for BOD, while Ogata-Banks has an error of 0.00287 for COD and 0.00417 for BOD.

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.
