In Indonesia, there are various environmental pollutants, one of which comes from household activities. Therefore, various ideas emerged in dealing with the polluted environment. One of them is using the phytoremediation method. In this study using wood apu (pistia stratiotest l) and water spinach (ipomea aquatica) grown using a hydroponic system. In hydroponics, there are two systems, namely DFT (deep flow technique) and NFT (nutrient film technique). In this study, using two kinds of systems, with the addition of aeration and without aeration, with variations in the distance between plants of 5cm, 10cm and 15cm and using two types of plants, namely water spinach and apu wood. The length of the study was 15 days, the first 7 days of acclimatization and the last 8 days of the main study. The results showed that the most optimal treatment was found in apu wood plants with a distance between plants of 5cm, with the addition of aeration and using the DFT system to achieve BOD 58.41%, COD 32.36% and TSS 62%.

Currently, the number of restaurant businesses is increasing. Wastewater caused by these restaurant activities will be a problem for the environment. Processing of restaurant wastewater can be done by biological treatment because it can reduce the organic content in wastewater. The biological processing process that can be used is the Moving Bed Biofilm Reactor (MBBR) system. The MBBR process in principle is biological growth using suspended and embedded cultures which are mixed in a reactor with aeration and moving media. This study aims to determine the performance of MBBR in reducing BOD, TOC and TSS in restaurant wastewater. The media used were Kaldness K3 and Bioball with various media compositions, namely 100% K3 Kaldness, 100% Bioball, 50% K3 Kaldness and 50% Bioball, 60% K3 Kaldness and 40% Bioball, 40% K3 Kaldness and 60% Bioball. The second variation is the sampling time, namely 3 hours, 6 hours, 9 hours, 12 hours, and 15 hours. Based on the results of this study indicate that the optimum MBBR reactor capability is with a composition of 100% K3 Kaldness at a sampling time of 15 hours. The reactor can reduce TOC by 97.84% and for the decrease in TSS by 76.84%.

Liquid waste generated from hotels has the same characteristics as household liquid waste. The characteristics are containing BOD and Ammonia. If the BOD and Ammonia content is disposed of without going through the processing unit, it will cause water pollution. To minimize BOD and Ammonia levels, efforts are needed through the Multi Soil Layering (MSL) process with adsorbent corn cob media, adsorbent clam shell media, or a combination of corn cob and clam shell media. This research is used to find out the effect of the comparison of variations soil and HLR using adsorbent corn cob media, clam shell, or combination to reduce BOD and Ammonia levels. This study uses a continuous system which is carried out with 2 treatment factors, there are soil variations (0:100, 25:75, 50:50, 75:25, 100:0) and HLR variations (100, 250, 500, 750, 1000 L/m2.hari). The best results obtained from this study were BOD removal with a combination of adsorbent corn cob media and adsorbent clam shell media with soil variation of 25:75 at HLR 100 L/m2.day of 86% with a concentration of 4.2 mg/L.

The total upstream surface water pollutant load has a lower value than the total downstream surface water pollutant load. Water flows from upstream to downstream which causes changes in water quality, therefore a study was conducted with the aim of knowing the effect of the amount of upstream surface water pollutant load on the amount of downstream surface water pollutant load in Kali Baru, South Jakarta. The analysis was conducted using a simple linear regression method with the predictor variable being the upstream surface water pollutant load (X) and the response variable being the downstream surface water pollutant load (Y). The results show a constant value (a) of 0.374 while the slope value (b) is 1.022 so that the regression model Y = 0.374 + 1.022 X is obtained. From the data it can be concluded that the amount of upstream surface water pollutant load has an influence on the amount of downstream surface water pollutant load of 0.374%, while 1.022% and the rest are influenced by external variables. Both variables have a strong relationship. The influence of the two variables is that if the amount of pollutant load entering the upstream surface water body increases, the amount of downstream surface water pollutant load will also increase.

Keeping the community comfortable while developing is very important and needs to be considered. Besides climate and air quality, another thing that must be considered is noise level. One of them is in Pasar Minggu, South Jakarta in the construction of Nusantara Student Dormitory Building. This journal aims to model the noise level as a reference material for the health of workers in the activity environment and calculate compensation to the local government or community due to the noise caused. To achieve this goal, the classification of points and sampling time is carried out. Each parameter affects the noise measured in dB. The parameter that most affects the presence of many activities in that period is the one with the highest weight. Then, in the form of noise contour modeling, the values of several parameters were analyzed. The results of the modeling show that at the location of the construction activities of the dormitory building there are several periods of time in which the weight of the noise exceeds the quality standard. The result of the highest Leq average measurement is 59.7 dB obtained at 17.00-22.00 WIB, while the highest Ls value is obtained from the 3rd sampling point of 60.4 dB. From the data, it is known that the noise level exceeds the quality standard set for residential areas. The standard set is 55 dB based on the Decree of the Minister of Environment No. 48/MENLH/11/1996.

Market is a place to conduct transactions in the form of buying and selling and provide the needs of both goods and services. In addition, the market also has many roles from the role for producers to development. In planning the placement of the market, the thing that needs to be considered is air quality. Therefore, in this study, air quality measurements were taken directly at three points around the market. The results of air quality measurements will be carried out a correlation test using minitab software to determine the relationship between pollutant parameters. Air quality parameters measured are Sulfur Dioxide (SO2), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Oxidant (O3) accordingly, Non-methane Hydrocarbons, Total Solid Particulates, Lead (Pb), PM 10, and PM 2.5. The measurement results of these air quality parameters still meet the quality standards according to PP No. 22 of 2021. There are four parameters with the same results at each measurement point, so the correlation test was carried out on parameters with different levels, namely Sulfur Dioxide (SO2), Total Solid Particulate (TSP), PM10, PM2.5, and Lead (Pb). Based on the results of the correlation test, it is found that the parameters that correlate with each other are PM10, PM2.5, and Total Solid Particulate Matter (TSP) parameters. In addition, the parameters of Lead (Pb) and Sulfur Dioxide (SO2) are also correlated with each other but not with other parameters.

Natural fiber reinforced composites are widely applied to equipment with materials that have a combination of two basic properties, namely strength and lightness. This study aims to determine the optimum ability of kenaf stem fiber and tobacco stem fiber which contain relatively high cellulose to be used as soundproofing materials and also to utilize tobacco stems which were originally considered as agricultural waste to become a more useful raw material. Comparison of stem fiber ratio kenaf and tobacco stem fiber 100:0, 60:40, 50:50, 40:60, and 0:100. From the research results obtained, the composite exhaust produces the smallest sound, namely 81.6 dBA at a fiber ratio variation of 60:40 at 1500 RPM and produces the biggest sound, namely 99.1 dBA at a fiber ratio variation of 0:100 at RPM 3500. Results it can be said that the damping of the composite exhaust is quite good because it is not too far from the quality standard threshold of 83 dBA. The ability of kenaf stem fiber to reduce noise is better than that of tobacco stem fiber because the cellulose content in kenaf stem fiber (by 50%) is higher than that of tobacco stem fiber (by 37%).
