COD dalam lindi merupakan salah satu parameter yang secara umum berada pada konsentrasi yang tiggi sebagai salah satu hasil biodegradasi material organik dan anorganik dalam sampah di TPA. Sistem evapotranspirasi yang menggunakan tumbuhan lokal merupakan salah satu sistem yang menjanjikan. Penelitian dilakukan untuk mengetahui efisiensi penyisihan COD dalam lindi dengan reaktor evapotranspirasi secara kontinyu yang menggunakan tumbuhan Tumbuhan Sente (Alocasia macrorrhiza) dan Rumput Belulang (Eleusine indica). Hasil uji menunjukkan efisiensi pada semua reaktor mulai sekitar hari ke 3 hingga hari ke 25 mengalami fluktuasi yang cenderung menurun (dari ± 75% menjadi ± 50%), tetapi hari selanjutnya cenderung meningkat. Pola tersebut dipengaruhi oleh peran media tanam, bakteri dalam media tanam, bakteri pada akar tumbuhan dan aktivitas metabolisme tumbuhan uji. Secara keseluruhan reaktor yang menggunakan Tumbuhan Sente (Alocasia macrorrhiza) lebih fluktuatif dibandingkan denga menggunakan Rumput Belulang (Eleusine indica) yang dipengaruhi pola pertumbuhan dan perkembangannya.

Growing of Eichhornia crassipes (Mart), Solms) depend on environmental factors e.g. material organics, sun lighting, water depth, salinity, and pH . However this plant have ability to absorb organic element, organic compound, and other chemical element that can be able to use as biological absorber in waste water treatment.The research is to know the effect of contact time and age of Eichhornia crassipes (Mart), Solms) toward of ammonia concentration in hospital waste water.The method of this research is Experimental design with One Group Pre Test Post Test Design. The outcome of the research have shown that average ammonia concentration decrease with young plants is 62,17 % at 2 days contact time, 87,1 % at 4 days contact time, and 94,3 % at 6 days contact time. With old plant ammonia concentration decrease 79,35 % at 2 days contac time, 97,61 at 4 days contact ime, and 98,4 % at 6 days contact time. From the result can be conclude that plant of Eichhornia crassipes (Mart), Solms) had significant ablility to descrease of ammonia concentration in waste water.

This research using the domestic organic garbage which is mixed by rice bran and cane pulp, with the variation of mixing pursuant to ratio C/N and moisture is, cane pulp : domestic organic garbage equal to 1:4, 2:7, rice bran : domestic organic garbage, 1:4, 2:7, and also the mixture cane pulp : domestic organic garbage : rice bran, 2:10:2, 1:7:1. Conduct attempted by aerobic and Mac Donald method. So that pursuant to the research can be taken conclusion that mixing lock up the rice bran and cane pulp with the domestic organic garbage is slow down the compost maturity so that unnecessary of cane pulp mixing and rice bran of at domestic organic garbage composting, compost quality of result of mixing as according to value of compost quality at SNI 19-7030-2004. Composition which it faster the compost maturity is control and composition which it has good ratio C/N from 6 variation is variation AS 27 which it consists of two cane pulp and seven domestic organic garbage.

ANALISIS SEBARAN TEMPERATUR DAN SALINITAS AIR LIMBAH PLTU-PLTGU BERDASARKAN SISTEM PEMETAAAN SPASIAL (STUDI KASUS : PLTU-PLTGU TAMBAK LOROK SEMARANG) Haryono Setiyo Huboyo; Badrus Zaman

Heat wastewater emitted by power plant near seashore will be dispersed to bulk seawater by stream. The main effects generated by this elevated streams is deteriorating of benthic and aquatic life productivity. Further impact is subjected to depleting dissolved oxygen and seawater salinity content. By means of spatial mapping, the pattern of temperature distribution would be revealed and its impact could be predicted by then. Measurements of 14 purposive sampling spots were conducted in the early morning, noon and afternoon within Tambak Lorok Port pond. Control measurements also were taken in the East side and West side of the pond. Temperature distribution observed from the early morning through the afternoon exhibited the same pattern with dissolved oxygen distribution as well as stream pattern. Turbidity distribution accumulated in the East side, mixed with domestic waste stream carrying large amount suspended solids. Salinity distribution showed a little bit different pattern with temperature distribution considering that salinity pattern was affected by incoming streams from bulk seawater in the Northwest and Northeast of the pond.

Estuary of River Babon very influenced by condition around its drainage basin. estuary of River Babon also have function as a channel of waste disposal from Terboyo Industrial Park, Semarang ( KITS). Cadmium ( Cd) as one of heavy metal pollutant and conservative element will certainly spread at estuarine. Based on research at the time of measurement, known that by the content of Cd at estuary of river Babon equal to ( 0,009 - 0,017) mg / l, where the concentration have exceeded the Quality of Water Go out to sea for the Biota of Go out to sea that is equal to 0.001 mg / l (Kep Men LH No. 51 tahun 2004). Study about disseminating polutan at estuarine can be conducted by using model because by using model can be knowable how disseminating polutan accurately, quickly and cheap so that picture from the model can be made basis for furthermore management. Model developed with numerical 2-D model ( lateral & longitude). Model developed by using equation on the basis of hydrodynamics process and conservative transpor polutan. The equation finished by numerik by using differential method ( finite difference). The result from developed model for the time of t = 1 hour obtained value with 3.028% mistake from field data.

Population growth, the increase in the industrial sector and the presence of waste from activities that haven’t been treated properly can make a water river being contaimined high pollutants. The pollutant parameters identified is Total Suspended Solid (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO) and E.Coli. One of the polluted rivers is Wonokromo River which is located in Surabaya City, according from monitoring results Balai Besar Wilayah Sungai (BBWS) Brantas in 2021 the pollutant value in river with TSS is 484 mg/L, BOD is 15.96 mg/L, COD 23.91 mg/L, DO 3.67 mg/L, and E.coli 4.283 MPN/100 ml from the monitoring data included polluted category. Depectin model of water river conditions using the STELLA program. The results indicate that the water quality of the Wonokromo River is polluted with the parameters TSS, BOD and E. Coli, determination refers to Goverment Regulations number 22 in 2021 about “Implementation of Environmental Protection and Management” in clasification II for raw water. So Wonokromo River is not suitable as a source of raw water in that year and a policy scenario is needed to reduce water river pollution.

Most community settlements in Indonesia do not have a household scale of a wastewater treatment plant. Fatal impacts on the environment and human health can occur at any time, including (a) causing environmental damage (disaster), (b) damaging beauty/aesthetics for the scenery will be unpleasant and foul-smelling, (c) polluting water bodies, and (d ) endangering health. The purpose of this study is to optimize the Multi Soil Layering (MSL) System to treat domestic wastewater (greywater) using environmentally friendly materials that are available in Indonesia. The research method used the MSL system with the first variation using a batch system with Hydraulic retention time (HRT) for 24 hours and the second variation using an intermittent system with 3, 6, 9 hours HRT. The results showed that the MSL system was able to eliminate COD well. The highest COD removal efficiency was 93.44% at 9 hours HRT, but the effluent quality did not meet the required quality standards. The development of MSL systems that produces an effluent quality that meets the quality standards needs to be studied further.
