Water pollution can not only be measured only by chemical and physical parameters, Plankton have properties that are always moving so that they can be used as indicators of water pollution. Plankton play an important role in influencing the primary productivity of river waters. The purpose of this study was to determine the relationship between the diversity and presence of plankton to the quality of the Batanghari River. The study was conducted in February 2018 in Jambi City. Primary data taken in the form of concentrations of physical and chemical parameters include turbidity, pH, TDS, BOD, COD, DO, Phosphate, Nitrate, Nitrite, Ammonia, Lead, Chloride, Sulfate and the amount of plankton abundance (ind / L) on the Batanghari River. The time of sampling was in the morning and evening on the same day. The results showed that the relationship between the existence of plankton and the quality of the Batanghari River showed the condition of the Batanghari River in Jambi City was in phase a - Mesosaprobic (heavy pollutant level). Parameters of pH, COD, Phosphate, Nitrite, Lead and Chloride are moderately correlated to phytoplankton, while TDS, BOD, DO, Nitrate and Ammonia are weakly correlated with phytoplankton. And for temperature parameters it is strongly correlated with phytoplankton. For correlation to zooplankton, parameters of pH, TDS, BOD, COD, COD, DO, Phosphate, Nitrate, Nitrite, Lead, chloride are very weakly correlated while ammonia and turbidity correlate moderately to zooplankton.

The Asam River is one of the rivers that crosses the sub-districts, including Kota Baru, Jelutung and Pasar Jambi. Asam River is located in Jambi City with a length of 10.68 km, and a watershed area of 2,930 Ha. The Asam River is generally polluted by waste originating from activities, office areas, hotels, trade centers, prominent figures and residential areas. To determine the quality of acid river water, it is necessary to analyze the load carrying capacity of water pollution. Methods that can be used to analyze the load carrying capacity of water pollution include the Mass Balance method and the Streeter-Phelps method. Based on the results of the calculation of the carrying capacity of the river pollution load using the mass balance method on the parameters, pH, TSS, BOD and COD. The Asam River which cannot accommodate the pollution load is found in the TSS parameter of -110.129 mg/l with a quality standard of 30 mg/l according to the Ministry of Environment and Forestry Number P.68 of 2016 concerning domestic waste quality standards, while for the parameters pH, BOD, and COD still below the domestic waste quality standard. The results of the calculation of the carrying capacity of the pollution load using the streeter-phelps method show that at 4 sampling points the BOD concentration can still accommodate the pollution load in the river which does not exceed the quality standard. the effect of DO concentration on AP1 Upstream to AP4 Downstream is still available in sufficient amount of DO.

One of the uses of organic waste is processing it into biomass briquettes which can later be used as energy. Organic waste received is dry organic waste such as dry leaves, dry twigs, inorganic waste such as plastic waste which can be used as an adhesive in making waste biobriquettes. The purpose of processing organic and inorganic waste into energy is to benefit from the waste in the city of Jambi. The benefit obtained is to reduce waste which can be used as energy. The kerosene to LPG conversion program has resulted in a rapid increase in LPG consumption which domestic production cannot meet. This causes LPG imports to increase rapidly, so that if in 2007 the volume of LPG imports was still at 137 thousand tons, in 2011 it increased to 1,992 thousand tons or an increase of almost 15 times (Outlook Energi Indonesia 2013). The highest calorific value with the optimum composition is found in biobriquette sample 3 with a variation of the composition of 75% organic waste: 5% inorganic waste: 10% water: 10% glue, which is 19361 J / gr. The lowest ash content with the optimum composition was found in sample 3 with a variation of the composition of 75% organic waste: 5% inorganic waste: 10% water: 10% glue, namely 5.06%. The lowest water content with the optimum composition is found in sample 1 and sample 2 with a water content of 0.92%, this is already in accordance with SNI for biobriquettes. The lowest CO content with the optimum composition is found in the biobriquette sample 1 with a variation of the organic composition of 85%: 5% inorganic: 5% water: 5% glue, which is 60.33 μg/Nm3.

Wastewater treatment is the main element in the success of a business in environmental management and monitoring, for this reason it is necessary to carry out maintenance and evaluation so that the sustainability of environmental protection continues. The crude rubber industry (crumb rubber) generally processes rubber in several stages, starting from sorting raw materials, cleaning bokars, macro mixing, pre-drying, crushing, drying and pressing, of course, this produces waste. The research method is evaluating the quality of wastewater from each treatment unit at the WWTP production of crumb rubber, as well as evaluating the WWTP units based on design criteria that are planned and described analytic descriptively. upon admission, namely COD of 12.876 mg/L, TSS of 1.112 mg/L, BOD5 of 980 mg/L, Ammonia 2.3 mg/L, Nitrogen 96 mg/L, pH 6.3. The results at the outlet are COD 19.35 mg/L, TSS 58.67 mg/L, BOD5 35.1 mg/L, Ammonia 0.2 mg/L, Nitrogen 10 mg/L, pH 7. While the WWTP unit design inefficient in terms of design criteria, this is because the residence time is calculated too quickly, therefore it is necessary to analyze the suitability of dimensions in order to meet the required design criteria.

Hotels produce wastewater as much as 80% of the total use of clean water, the wastewater is categorized as domestic wastewater. Hotel X is a 4-star hotel with a need for clean water of 64,396 m3/day and the waste water produced is 49.33 m3/day. Based on observations and evaluations, it was concluded that Hotel X's wastewater was treated at the WWTP with performance that was still not optimal. So that the method used in this research is descriptively analyzing primary and secondary data, then proceed with evaluation and redesign of certain WWTP units based on existing conditions in the field. Laboratory test results show that the parameters that do not meet the quality standards are TSS 136 mg/L, BOD5 56 mg/L, and COD 174 mg/L, so the units that need to be evaluated based on existing conditions consists of grit chamber units, equalizing tanks, anaerobic tank, aerobic tanks, sludge tanks and sedimentation tanks. Based on the results of the evaluation on the existing WWTP unit at Hotel X, there are WWTP units that need to be optimized, namely equalizing tanks and aerobic tanks, where the detention time exceeds the design criteria. Redesign of dimensional changes to the equalizing tank and aerobic tank units. Based on the calculation results, the detention time in the equalizing tank was 8.5 hours and in the aerobic tank 14.38 hours. The equalizing tank unit has been modified to a depth of 2 m to reduce detention time in the initial processing to 6.8 hours, while for the aerobic tank 2 unit, it is modified to a width of 2.5 m and a length of 2.5 m, the length and width of the aerobic tank unit 2 is equated with the size of tube 1 to reduce detention time in processing to 7.6 hours.
