Wastewater generated from the tofu industry usually still contains high organic pollutants that can contaminate the surface water. Therefore, it should be treated properly before it can be disposed to the environment. This study aims to evaluate the combination of coagulationflocculation and ultrafiltration methods in treating the wastewater from tofu industry. Based on the preliminary tests, the wastewater from tofu industry have pH, total dissolved solid (TDS), total suspended solid (TSS), turbidity and chemical oxygen demand (COD) of 3.4, 870 - 1080 mg/L, 370 mg/L, 446 FAU and 7954 mg/L, respectively. The coagulant and membrane used in this study were Poly aluminum chloride (PAC) and the ceramic membrane, respectively. Experimental results showed that the best pH for coagulation-flocculation process is at pH of 7.0, and this pH was then used for ultrafiltration process. The flux of the ultrafiltration membrane increased with increasing the trans membrane pressure due to increasing driving force. The observed parameters such as TSS and turbidity of wastewater decreased drastically after experiencing ultrafiltration process and met the National Environmental Quality Standard. However, the COD of water produced in the ultrafiltration process was still high and did not meet the National Environmental Quality Standard.

<p><strong>Abstract</strong></p><p>Segara Anakan, Cilacap Regency is an important marine fisheries producer in Central Java <br />Province, especially for shrimps. The objective of this study were to analyze the production and <br />fishing ground of shrimps, to analyze dynamic patterns of shrimps cat ch affected by sedimentation <br />and  industrial waste in Segara  Anakan, and to develop intervention option to the degradation  of <br />shrimp  catch  as  well.   Some  methods  were  used  in  this  study  such  as  descriptive  method, <br />geographic information system, and dynamic model approach included the test of model structural <br />stability and performance. In  2002–2013, the highest production of shrimps in the Segara Anakan <br />was in 2006 (2263.0 ton) and the lowest was in 2010 (884.7 ton). Fishing ground of shrimp in the <br />Segara  Anakan  already  had high total suspended solid, and also  low contaminated oil and  lead <br />(Pb). Results of dynamic model analysis showed that shrimp catch degraded exponentially along <br />with the increasing of sediment accumulation and industrial waste. Shrimps production in 2013 was <br />1147.8  tons,  and  might  decrease   43.04  %  to  be  653.8  tons  over  75  years  later  without <br />intervention. If the model was intervenced by fishing open -close system and limited acces fishing <br />ground,  hence  shrimps  catch  showing  stable  around  902.2–929.1  ton  every  year.  While  if  the <br />intervention was conducted by the stopping of industrial waste to Segara Anakan, hence shrimps <br />catch only decrease 13.00 % to be 998.6 tons over 75 years later.<br /><br />Keywords: dynamic model, fishing ground, industrial waste, shrimp catch</p><p><strong><br /></strong></p><p><strong>Abstrak</strong></p><p><strong></strong>ABSTRAK<br />Segara Anakan, Kabupaten Cilacap merupakan basis produksi perikanan laut yang penting <br />di  Provinsi  Jawa  Tengah  terutama  jenis  udang.   Penelitian  ini  bertujuan  menganalisis  kondisi <br />produksi dan daerah penangkapan udang, menganalisis pola dinamis penurunan hasil tangkapan <br />udang  akibat  pengaruh  pengendapan  dan  pembuangan  limbah  industri  di  kawasan  Segara <br />Anakan,  serta  mengembangkan  alternatif  intervensi  secara  modelling  terhadap  penurunan <br />tersebut.  Metode  yang  digunakan  terdiri  dari  metode  deskriptif,  sistem  informasi  geografi, <br />pendekatan  model  dinamis,  serta  uji  kestabilan  struktur  dan  kinerja  model.  Pada  periode  tahun <br />2002  –  2013, produksi tertinggi udang terjadi pada tahun 2006 (2263,0 ton) dan terendah terjadi <br />pada tahun 2010 (884,7 ton). Daerah penangkapan udang di kawasan Segara Anakan mempunyai <br />total padatan tersuspensi dan kekeruhan yang tinggi, serta tercemar ring an oleh minyak dan logam timbal. Analisis model dinamis menunjukkan bahwa hasil tangkapan udang cenderung menurun <br />secara eksponensial seiring meningkatnya akumulasi endapan  dan cemaran limbah industri dari <br />waktu  ke  waktu.  Hasil  tangkapan  udang  yang  saat  ini  (tahun  2013)  mencapai  1147,8  ton,  bisa <br />menurun 43,04 % menjadi 653,8 ton setelah 75 tahun kemudian. Bila model tersebut diintervensi <br />dalam  bentuk  penerapan  sistem  open-close  dan  pembatasan  daerah  penangkapan  yang  bisa <br />diakses,  maka  hasil  tangkapan  udang  cenderung  stabil  pada  kisaran  angka  902,2  –  929,1  ton <br />setiap  tahunnya.   Akan  tetapi  bila  intervensi  dilakukan  dalam  bentuk  penghentian  pembuangan <br />limbah industri ke kawasan Segara  Anakan  dan sekitarnya, maka hasil  tangkapan udang hanya <br />turun 13,00 % (menjadi 998,6 ton) setelah 75 tahun kemudian.<br /><br />Kata kunci: model dinamis, daerah penangkapan, limbah industri, hasil tangkapan udang</p>

The dug well water quality in community settlements needs assessment to ensure its quality. The water has to meet the required physical, chemical, and bacteriological standards. This initial research aimed to determine the dug well water quality in Kampung Ujung, Komodo District, Labuan Bajo City, WestManggarai Regency in September 2019. The research method was used survey and laboratory. The two dug well was taken used a purposive sampling technique. The test parameters include temperature, turbidity, pH, smell, Total Suspended Solid (TSS), sulfate, Total Dissolved Solid (TDS), nitrate, nitrite, Total Hardness, Dissolved Oxygen (DO), nitrogen ammonia, total coliforms, and Escherichia coli. The analysis physically, chemically, and biologically of two dug well water samples were had done examined. The result showed that the parameters of TDS, nitrate, nitrite, E. coli, and DO exceed the Class I Water Quality Standard. The research concluded that the quality of both dug well water in the Kampung Ujung Labuan Bajo area was not suitable for use as material raw drinking water. Furthermore, the government should provide other water sources such as the addition of storage tanks for raw water, so that people do not entirely depend on dug well water.

The problem that occurs in Lake Sentani is that it has been contaminated by parameters of TSS, BOD, Pb, Cu, and DO respectively with valuesof 76 mg / L, 4.63 mg / L, 0.035 mg / L, 0.03 mg / L, and 5.72 mg / L because these parameters have exceeded the quality standard according to environmental regulations. This study aims to determine the assimilation capacity of TSS and PO4 parameters and analyze pollution control models in the Tlaga Ria sub-watershed. The research method used to determine the assimilation capacity is a linear regression equation and in analyzing the pollution control model the interpretative structural modeling method is used. The results showed that the TSS assimilation capacity value in Lake Sentani was -12,700 tons/month. The value of water quality in Lake Sentani is above the value of the assimilation capacity, this shows that Lake Sentani has been polluted by TSS parameters. Meanwhile, the value of PO4 parameter assimilation capacity is 44.36 tons/month and since 2016 Lake Sentani has been unable to conduct self purification. The key elements of the Sentani Lake pollution control constraints in the Tlaga Ria watershed are weak implementation of environmental regulations, differences in objectives among stakeholders, differences in objectives between administrative areas, weak support of business owners, conflict of interests, and weak enforcement of regulations.

As a developing country and one of the tropical tourism industry leaders, Malaysia is faced with environmental problems, such as the conversion of municipal solid waste landfill leachate into hazardous wastewater in mega cities. High concentrations of pollutants, toxic refractory component, and complex composition of landfill leachate have serious environmental impact. This study investigated a novel rapid treatment method to remove turbidity, suspended solid, color, and ammonia nitrogen. Bentonite augmented sequencing batch reactor with miscellaneous aeration (0.5–7.5 L/min) and contact time (1–3 h) is applied via response surface methodology in 13 runs. Results of this study show that in optimum circumstances, 93.63% of turbidity, 90.42% of total suspended solid, 76.33% of ammonia nitrogen (AN), and 45.96% color were removed in only three hours. Furthermore, natural bentonite is a cost effective adsorbent for landfill leachate treatment.

Tofu wastewater from the tofu industry includes the process of washing soybeans, the use of tools, washing the floor, and cooking as well as the solution of the remaining soaking soybean. Concentration of tofu wastewater pollutant in particular total suspended solid (TSS) exceeds the quality standard of wastewater that has been stipulated in the Minister of Environment Regulation no. 5 of 2014. In this study, tofu wastewater treatment is carried out by the adsorption process in the batch system. Adsorbent used is coconut fiber. Analysis of the influence of independent variables, namely adsorbent weight, stirring speed and contact time on TSS adsorption was carried out using the response surface method approach. Adsorption process can reduce TSS from tofu wastewater to the range of 52-370 mg/L. The independent variable that most influences the dependent variable based on statistical analysis is contact time. The optimum TSS adsorption conditions based on analysis using the Design Expert 11 Application were reached at 40 minutes contact time.

In this study, integrated pretreatments and aerobic digestion processes were investigated in order to provide a feasible alternative that can achieve effective sludge reduction. An ozone treatment in the presence of ionic manganese, a catalyst, increased the sludge reduction ratio three times higher than that of a single ozonation, presumably due to an increase in OH radical production. The ozone treatment yielded the effective sludge reduction ratio with an increasing ozone dosage, and an effective dosage of the catalyst was found to be 4 mg-Mn/g-TS. When a mechanical pretreatment and an ozone/catalyst were applied in a series, the integrated process, even at a half mechanical intensity and a half level of ozone dosage, showed higher and faster sludge reduction than each single process did. In addition, the integrated pretreatment process showed the highest dewaterability of the treated sludges. A ratio of sludge cake generation, which was newly introduced to quantify overall performance of sludge treatment processes, showed that the integrated pretreatment followed by the aerobic digestion yielded approximately a half of the sludge cake volume compared to the single aerobic digestion. Therefore, the integrated pretreatment can be a feasible method for the effective reduction of total suspended solid and the final volume.
