Abstract Through our academic research we developed a control mechanism for translation based on seven variables derived from the studies of the Belgian translatologist Dirk Delabastita. In this paper we implement the control mechanism for translation in the fields of solid waste management and liquid waste mechanics using the academic text-books Handbook of Solid Waste Management and Wastewater Engineering, Treatment and Reuse in order to investigate the quality of translations in Greek. We present an indicative psychometric questionnaire from the initial research conducted with telecommunications scientists, as well as an abstract outlining the processing of the relevant indices, followed by indicative processing in the academic field of environmental engineering. This could be the first step in research for the field of environmental engineering terminology.

Potential Pollution

Canteen is a producer of domestic liquid waste that has the potential to cause pollution. Likewise with the student canteen, it has the potential to produce waste that causes environmental pollution if it is not treated properly. The use of Montecarlo software in this study is to support quantitative analysis in predicting potential pollution from Ubhara canteen waste with Crystall ball prediction. The results of laboratory analysis in the form COD, BOD dan TSS, showed that the quality of the canteen waste water did not meet the requirements for wastewater quality standard based on Ministry of Environment Decree No. 112 of 2003. Supported by the results of CB Predictor simulations showing the potential of pollution of the Ubhara canteen waste water to the environment continues to increase significantly, also seen from the Double Exponential Smoothing Method, producing MAD (Mean Absolute Deviation) 170.82, Theil's U 0.9951, and Confidence Interval Lower 5% and Upper 99.5%.

One of the most promising ways of recycling waste oil and oil refining industries, in particular oil sludge, is their processing into valuable building and road materials. Solving this issue can help reduce the negative impact on the environment, rational use of natural resources and improve the state's economy. In this regard, it is important to conduct research on the physical and chemical properties and thermal characteristics of oil sludge samples taken under the conditions of Pavlodar Petrochemical Plant LLP, which was the purpose of this work.

This study aims to (1). Knowing the content and quality of Rahayu's tofu and tempe factory liquidwaste in Uner Village, Kawangkoan Sub-district, Minahasa Regency, and (2). To find out whether Rahayu's tofu and tempe factory liquid waste has exceeded the quality standard. This research was conducted for 3 months, namely in January 2020- March 2020. Sampling locations were carried out in the factory of Tahu and Tempe Rahayu Sub-district in Uner Village, Kawangkoan District, then continued with the analysis at the Manado Industrial Research and Standardization Laboratory (Baristand). This research was a descriptive research and laboratory analysis. Waste water sampling was carried out using a composite sampling method. Sampling was done in the first two places, raw water is used to make tofu and tempe in an inlet and the first was taken from the tofu factory wastewater and tempe in the sewer. Waste liquid sampling was carried out 3 times and for analysis carried out at the Baristand Laboratory to obtain data according to the parameters set in this study. The results showed that the quality of Rahayu tofu and tempe industrial liquid waste based on the analysis of BOD, COD, and TSS parameters that have been analyzed accordingly and have not passed the quality standards set by the Government. However, for the pH parameters are not appropriate and in accordance with the quality standards set by Government.*eprm*

Research on metal adsorption isotherms with activated carbon oil palm empty fruit bunches in liquid waste. Oil palm empty fruit bunches are used as adsorbent for metal absorption. Oil palm empty fruit bunches are prepared at 105O C for 24 hours to get a constant weight then are characterized by SEM. Oil palm empty fruit bunches are heated at temperatures (400O C – 700O C) to get activated carbon. Re-characterization using SEM at optimum conditions shows that the pore surface is expanding. Then with a batch method for metal absorption (Cu, Pb, Hg) and analyzed using AAS. The most common absorption of activated carbon of oil palm empty fruit bunches is Cu (II). Based on the Langmuir and Freundlich R2 models close to 1, which means that multi-layer adsorption occurs.

During the production of batik cual, thick-colored wastewater is produced. Unfortunately, the wastewater could damage the environment if it is disposed of without specific processing. The Fenton method is an advanced oxidation process (AOPs) that can degrade organic dyes found in liquid waste. In this research, the researchers studied the Fenton mechanism's application to the batik cual wastewater treatment. The Fenton's reagent used was H2O2 with FeSO4.7H2O. Some of the experimental wastewater treatment parameters were the values of biological oxygen demand (BOD), chemical oxygen demand (COD), the degradation efficiency of difficult to decompose organic materials, and the color degradation efficiency in batik cual wastewater. The results show that the Fenton mechanism’s efficiency of removing color from batik cual wastewater is up to 97.8%, COD and BOD removal efficiencies are 76.3% and 75.2%, and the degradation efficiency of difficult to decompose organic matter is 76.8%. Also, the researchers found that the higher amounts of FeSO4.7H2O increase the removal parameters effectiveness. Therefore, the Fenton mechanism can effectively improve the quality of wastewater in batik cual production.

In general, water conditions surrounding Bunaken Island are not separated from the liquid waste disposal, for example: bathing, washing, latrines, and landfills. Based on this, the research was conducted to determine the content of microorganisms Escherichia coli and coliform derived from liquid waste around Bunaken Island. The result showed the concentrations of E. coli were point (TS) I (<1 MPN / 100 ml), II (<1 MPN / 100 ml), and III (<1 MPN / 100 ml), and at the sampling point (TS) IV (1.0 MPN / 100 ml), V (1.0 MPN / 100 ml), and VI (1.0 MPN / 100 ml). Furthermore, coliform concentration has the similar valueat each sampling points (TS) I, II, III, IV, V, and VI with the amount of 2.0 MPN / 100 ml. The status around the Bunaken island on the comparison table between the this results and the standards of the Sea Quality Standard for Marine Tourism still qualifies or does not exceed the limits which stated in the creed of Minister ofEnviromental Affair Republic of Indonesia number 179 of 2004. Followed by Creed of Minister ofEnviromental Affair number 51 of 2004 on the Quality of Raw Water for Marine Biota, is categorized as the "proper" one of sea water quality for marine biota on the based ofEscherichia coli and coliform ratio.Keywords: Escherichia coli, coliform, air quality, Bunaken Island, North SulawesiPada umumnya, kondisi perairan yang berada di sekitar Pulau Bunaken tidak terlepas dari pembuangan limbah cair, misalnya : mandi, cuci dan kakus, serta tempat pembuangan sampah. Bertolak dari hal tersebut, penelitian ini dilakukan untuk mengkaji keberadaan kualitas limbah cair dalam aspek mikroorganisme di perairan sekitar pulau Bunaken dengan mengukur konsentrasi Escherichia coli dan coliform.Konsentrasi Escherichia coli berturut-turut pada titik sampling (TS) I (<1 MPN/100 ml), II (<1 MPN/100 ml) , dan III (<1 MPN/100 ml), dan pada titik sampling (TS) IV (1,0 MPN/100 ml), V (1,0 MPN/100 ml) , dan VI (1,0 MPN/100 ml). Coliformmemiliki jumlah konsentrasi yang sama, yaitu berturut-turut pada titik sampling (TS) I, II, III, IV, V, dan VI dengan jumlah 2.0 MPN/100 ml.Status perairan sekitar pulau Bunaken pada tabel perbandingan antara hasil pengukuran dan standart Baku Mutu Air Laut Untuk Wisata Bahari, masih memenuhi syarat atau tidak melewati batas yang ditetapkan dalam KEPMEN L.H. No.179 tahun 2004.Sedangkan berdasarkan KEPMEN L.H. No.51 Tahun 2004 tentang Baku Mutu Air Laut Untuk Biota Laut, berada dalam kategori “layak” sebagai peruntukan air laut untuk biota laut, berdasarkan parameter Escherichia coli dan coliform.Kata Kunci :Escherichia coli, coliform, kualitas air, Pulau Bunaken, Sulawesi Utara
