Abstract Wastewaters from chemical industries usually contain pollutants which are toxic and non-biodegradable. Treatment of chemical wastewaters is always a challenging topic in view of the stringent environmental regulations that have to be adhered to. Since 2014, the Chinese government has been continuously tightening the industrial wastewater (IWW) discharge standards, which requires improved quality of IWW effluent. This poses great challenges to the chemical industries in China, especially to many of the chemical industry clusters where the wastewaters usually contain more toxic and non-biodegradable contaminants. Membrane bioreactor (MBR) technology has been proved to be a reliable and cost-effective solution for the treatment of IWW. However, MBR alone could not effectively remove non-biodegradable organics, it needs to be integrated with advanced oxidization process and/or other physical-chemical treatment processes to improve the overall treatment efficiency. In this paper, studies on the performance of different integrated MBR processes in Industrial Wastewater Treatment Plant-A (IWTP-A) will be discussed, including Fenton + MBR, MBR + ozonation + biological aerated filter, and MBR + porous resin sorption.

The location of tempe processing adjacent to the settlement causes problems. The resulting liquid waste makes people uncomfortable. This is presumably because the liquid waste has not been managed properly, because it is only dumped into the drainage channel. The majority of tempe industrial entrepreneurs are home industries who are not aware of creating a healthy environment by paying attention to liquid waste processing. There are many studies on technology for the tempe industrial wastewater problem, but each technology has advantages and disadvantages. It is necessary to have a system to choose the technology that suits the waste conditions. This research takes a case study in Karanganyar Regency. The Analytical Hierarchy Process (AHP) method is a method of determining priority scale that can accommodate all aspects. Furthermore, a sequence of criteria can be arranged as needed. The results of the analysis with AHP are: technology criteria 31.09%; environment 28.65%; economic 21.74% and social 18.53%. Environmental sub-criteria showed the results of the removal of ammonia 40.56%; treated water quality 30.74%; the amount of mud is 18.91% and the emission level is 9.80%. Technology sub-criteria are ease of operation 28.67%; land area requirement 28.56%; service life of 28.05% and the potential of technology in the midification of 14.72%. Economic sub-criteria with the results of operating costs 34.21%; installation cost 33.28%; maintenance costs 23.78% and HR costs 8.73%. Social sub-criteria with the results of the need for employment of 49.10%; readiness of human resources 19.33%; implementation of construction 16.74% and aesthetics 14.82%. The results of the AHP can be used as input for tempe entrepreneurs, the government and the community to improve the environmental quality of the tempe industrial wastewater. It is hoped that entrepreneurs will find it easier to determine the appropriate technology to treat the tempe industrial liquid waste.

Purpose Misophonia is a sound tolerance disorder condition in certain sounds that trigger intense emotional or physiological responses. While some persons may experience misophonia, a few patients suffer from misophonia. However, there is a dearth of literature on audiological assessment and management of persons with misophonia. The purpose of this report is to discuss the assessment of misophonia and highlight the management option that helped a patient with misophonia. Method A case study of a 26-year-old woman with the complaint of decreased tolerance to specific sounds affecting quality of life is reported. Audiological assessment differentiated misophonia from hyperacusis. Management included retraining counseling as well as desensitization and habituation therapy based on the principles described by P. J. Jastreboff and Jastreboff (2014). A misophonia questionnaire was administered at regular intervals to monitor the effectiveness of therapy. Results A detailed case history and audiological evaluations including pure-tone audiogram and Johnson Hyperacusis Index revealed the presence of misophonia. The patient benefitted from intervention, and the scores of the misophonia questionnaire indicated a decrease in the severity of the problem. Conclusions It is important to differentially diagnose misophonia and hyperacusis in persons with sound tolerance disorders. Retraining counseling as well as desensitization and habituation therapy can help patients who suffer from misophonia.

So far, in implementing school strategies, they tend not to utilize Information and Communication Technology (ICT), despite the availability of ICT resources available. Stages of strategic management are needed to generate the vision, mission, objectives, policy, program, budget, and procedures as well as control and evaluation process as an effort to utilize ICT to improve school quality. Based on the interpretation and the results of the study, it is concluded that schools have organized stages in strategic management that enable schools to have a quality profile. The impact of effective utilization of ICTs for schools is the achievement of effective school management, as per the National Education Standards, which is characterized by effective planning, implementation, control, and evaluation of school ICTs.The purpose of this study is to get a general description, describe, and reveal the Strategic Management of Information and Communication Technology Utilization to Improve the Quality of School Learning in Ciledug Al Musaddadiyah Vocational High School and Garut 1 Vocational High School, both on environmental analysis, strategic formulation, implementation and strategic evaluation. The research method used in this research is the case study method, because the problems studied occur in the place and situation of Ciledug Al Musaddadiyah Vocational School and Vocational High School 1 Garut. The use of case study models in this study is based on the consideration that to provide an overview of the strategic management activities of the use of ICTs carried out at vocational high schools with the ultimate goal of being able to improve the quality of school learning. Based on observations in the field of SMK 1 Garut and SMK Al Musaddadiyah Ciledug Garut is one of the public schools and private schools that have these advantages.

Animal feed knife is a tool that serves to cut and chop animal feed consisting of grass as the main ingredient with additives such as bran, herbs, centrate, cassava, tofu pulp and others. Therefore, as a cutting tool must have the properties of friction resistance, impact resistance, and have good sharpness, so that the material chosen is Ni-Hard 1. The use of centrifugal casting method was chosen because it has the advantage of being able to make castings with relatively thin thickness this is due to the influence of the centrifugal force on the distribution of metal liquids throughout the cavity in the mold. Case study in this study is the use of centrifugal casting methods as an alternative to gravity casting methods to overcome defects of misruns. This research was conducted to investigate the effect of speed on the formation of castings products. The method that was carried out began with a literature study on centrifugal casting, and continued by determining the material, the temperature of the cast is in the range 1250ºC - 1300ºC, and the type of mold. The next step is to do work drawings, pattern making, mold making, casting processes, fettling processes, and analysis. With variations in speed of 200 rpm, 300 rpm and 400 rpm, it can be seen the optimal speed for making this product. The results of this study obtained optimal speed at a speed of 300 rpm to make good quality of animal feed knife products.
