Abstract

This study aimed to determine the relationship between nutritional intake and breast milk production in mothers who breastfeed babies aged 0-6 months at Langa Health Center, Ngada Regency. This study was an analytic survey with a cross sectional design. The sample of this study amounted to 75 respondents consisting of mothers who breastfed babies aged 0-6 months at Langa Health Center, Ngada Regency. The sampling technique used probability sampling technique with simple random sampling technique. The results of the multiple regression equation showed that the variables X3 (fat), X4 (carbohydrate), X5 (vitamin A), X11 (zinc), X12 (vitamin D), X13 (vitamin B12), and X14 (sulfur) had positive values, which means that there is a unidirectional influence between the independent variable (nutritional intake) and the dependent variable (breast milk production). The results of statistical calculations obtained the correlation coefficient is r = 0.429, meaning that it has a moderate relationship with the coefficient of determination / square is 0.184 or equal to 18.4%. And from the calculation results it is known that the variable X3 (fat) obtained a t-count of (2.226) ˃ t-table (1.670) and obtained a significant value of 0.030 <0.05, it can be concluded that fat affects milk production, so the hypothesis is accepted. From the results of the study, it is expected that breastfeeding mothers and the Langa Health Center share information about sources of nutritional intake, so that the increase in breast milk production for breastfeeding mothers can be guaranteed.

Abstract

Laundry waste that comes from home laundry still often discharges its waste directly into water bodies. This can cause pollution because laundry waste contains quite a lot of pollutants such as phosphate and BOD derived from detergent raw materials used also come from dirt loss when washing clothes. Apu wood roots that are fibrous and have fine hair allow the growth of microorganisms in the rhizosphere that can degrade organic substances contained in waste, to then be absorbed by plants as nutrients. Aeration is also done to help meet the oxygen supply needed by microorganisms to be able to degrade pollutants contained in waste. The purpose of this study is to see the ability of apu wood plants to remove levels of pollutants, namely BOD and Phosphate, also to see which variations of aeration are best to help remove BOD and Phosphate levels contained in waste. From this study, the best results were obtained that the largest BOD removal was 85.71% on day 9 with full 24-hour aeration, and phosphate by 74% on day 9 with full 24-hour aeration.

Abstract

The water of Kali Jagir, Surabaya, used as a raw water source, has been contaminated with high levels of BOD, COD, and permanganate. Therefore, this research seeks to address these issues by combining slow sand filtration with various media, including geotekstil and activated carbon. The study aims to optimize this combination in reducing parameters such as permanganate and total coliform in the raw water. The research methodology includes literature review, testing of raw water characteristics, preparation of slow sand filter reactors, preparation of filter media, and testing of media variations with an observation of organic and bacteriological pollutant removal efficiency. The results show that the combination of filter media involving sand, activated carbon, and geotekstil is effective in reducing organic pollutants. Geotekstil aids in the growth of the schmutzdecke layer and facilitates cleaning, while sand and activated carbon tend not to support such growth. Moreover, the optimum schmutzdecke growth time varies depending on the type of media used. These findings have significant implications for raw water treatment in industrial areas vulnerable to pollution, resulting in quality drinking water and addressing the frequent clogging issues in slow sand filters.

Abstract

A Water Treatment Unit (WTU) is a station that works on the processing and conditioning of raw water to meet the desired water quality. Water purification at PT. XYZ Kuala Tanjung uses raw water sourced from surface water or rivers. The river water used still contains solid substances and organic matter that render the water unsuitable for industrial use. Both suspended and colloidal solid substances can cause turbidity. Turbidity caused by solid substances can be addressed using coagulation techniques. The purpose of this research is to determine the optimal concentration and dosage of coagulant to clarify water in the WTU. The coagulant used is polyaluminum chloride (PAC). The research method is based on experiments using jar tests and stoichiometric calculations. The determination of the optimal coagulant is measured based on turbidity parameters. Experiments are conducted with varying concentrations of PAC ranging from 25-65 ppm, and the smallest turbidity value obtained is 1.21 NTU at a PAC concentration of 65 ppm, with a PAC requirement of 202.6679 kg/day. The higher the PAC concentration, the clearer the resulting water, but the daily requirement for PAC also increases.

Abstract

Weeds are botanical organisms deemed undesirable within a designated planting area due to their potential to diminish the value of cultivated plants and engender competition with the primary crop. The coexistence of weeds with primary crops can exert a significant influence. The present study used an exploration method was conducted inside the Gymnosperms collection at the Bogor Botanic Gardens, specifically focusing on sections II.E, V.F, and XV.A. A total of 38 distinct weed species exist, belonging to 25 different plant families. Among these groups, the two most prominent ones are Asteraceae and Commelinaceae. One of the numerous contemporary approaches to weed management involves the utilization of herbicides, as this strategy is widely seen as more effective in terms of cost, time, and labor efficiency.

Abstract

However, the people who work as fishermen feel disadvantaged because they cannot find fish and other marine animals as a livelihood due to the damage to the marine ecosystem caused by PLTU waste. However, people who work as fishermen feel lost because they cannot find fish and other marine animals as a livelihood due to damage to the marine ecosystem caused by PLTU waste. This literature review aims to provide information to the company, government, and community regarding the impacts caused by the existence of the Teluk Sepang PLTU and recommendations for solutions that can be applied to minimise the impact of pollution. The results of the review show that the discharge of wastewater from the Teluk Sepang PLTU has the potential to cause the parameters of temperature, salinity, pH, and turbidity of seawater to be incompatible with quality standards. Damage to marine ecosystems can also be caused by coal spills from barges. This causes all marine ecosystems to be disrupted, ultimately causing the community to experience economic losses. Three strategies can be recommended in an effort to control marine pollution due to the presence of the Teluk Sepang PLTU, namely increasing the efficiency of coal fuel use, managing liquid waste effectively, and increasing water use efficiency.

Abstract

One of the rivers in Bojonegoro Regency is the Gandong River where the surrounding community uses the Gandong River for irrigation of agricultural land, transportation facilities, and household activities. The decline in water quality along the river is caused by factors such as population density, waste from activities, and the use of rivers that are not in accordance with their uses. This study aims to determine the quality of surface water and determine how to control water pollution in Gandong River, Bojonegoro Regency. The purposive sampling method was used to determine the sampling location at two points, namely the upstream and downstream parts of the river. Data analysis uses a quantitative approach and describes the results of research observations which are then compared with water quality standards that have been determined based on PP No. 22 of 2021 concerning the Implementation of Environmental Protection and Management. The condition of the Gandong River water quality seen from the measurement results on the BOD parameter at point 1 and point 2, namely 6 mg/L and 7 mg/L, does not meet the quality standards. While the parameters TDS, TSS, pH, COD, DO, and Total Coliform still meet the quality standards. To control pollution in the Gondang River, a strategy of periodic inspection of river water quality is needed even though most river water quality parameters are still within the quality standards.

Abstract

Markets are places that facilitate buying and selling activities and are visited by many people, it making them vulnerable to the spread of a disease that can come from virus-carrying animals or inadequate sanitation. A healthy market should have good sanitation, such as adequate availability of water as sanitary higiene with adequate quality. Water used for sanitary hygiene purposes must be protected from pollutant sources and safe from contamination, and meet quality standards according to Regulation of the Minister of Health No. 32 of 2017. Therefore, to determine the quality of water that will be used to meet the sanitation needs of the market, this study measured the quality of clean water directly at three points around the location of the “Pasar Agro” development plan. Water quality measurements are carried out using methods according to the Indonesian National Standard according to each parameter to be measured. Based on the results of the measurements carried out, there are two chemical parameters that have not met, namely manganese and detergent parameters, as well as biological parameters in the form of total coliform. Correlation testing was carried out using Minitab 17 software on water chemistry parameters to determine the relationship between parameters, and it was found that there were only a few parameters that were related to each other.

Abstract

The amount of surface water pollutant load in the upstream tends to be lower when compared to the amount of surface water pollutant load in the downstream, this is due to the flow of water flowing from upstream to downstream and resulting in changes in surface water quality. Therefore, the purpose of this study is to understand the relationship between the level of surface water pollutant load in the upstream and downstream areas of Greges River, Surabaya by utilizing SPSS 23 software. The analysis method utilized refers to the simple linear regression method. The results of the analysis showed that with a significance level of less than (<) 5%, it can be concluded that there is an indication of an acceptable relationship between upstream surface water quality and downstream surface water quality. Simultaneously, the upstream surface water quality has a significant effect on the downstream surface water quality of Greges River, with the level of relationship reaching 85.7%, meaning that there is a very strong linear relationship between the upstream surface water quality and the downstream surface water quality it produces.

Abstract

The surface water of the Mertasari River (upstream) in Jembrana Regency, Bali is polluted with waste water due to the activities of the Negara Public Market (PUN). So that the quality of surface water decreases which is characterized by increasing levels of pollutant parameters. This study aims to determine the effectiveness of simple filtration tests with variations in the arrangement of filter media to reduce BOD5 and COD that exceed quality standards. The research method uses purposive sampling to determine the sampling location. From the results of water quality, the values of 8 mg/L and 29 mg/L respectively were obtained, which did not meet the quality standards based on Government Regulation of the Republic of Indonesia No. 22 of 2021. The arrangement used for filter media consists of palm fiber, sand, gravel, activated carbon, and zeolite. The filtration test treatment was carried out with three sampling times for each parameter with the amount of removal obtained BOD5 by 93.75% and COD by 96.14%. From these results, the final value of the BOD5 parameter is 0.9 mg/L and COD is 1.12 mg/L. So from the test results, simple filtration with the specified media arrangement is considered effective in reducing BOD5 and COD pollutant levels in surface water bodies around the State Public Market.
