Abstract

The Batik industry is one of the industrial sectors that has an important role in improving the economy. As time goes by, the demand for batik is increasing. Not only favored by adults and the upper class, but batik is also increasingly favored by the youngsters. Therefore, batik industry craftsmen continue to follow technological developments in order to be able to meet the demand for batik, as in the batik industrial area of Kampung Batik Laweyan. Some of the equipment used is still relatively simple, but the use of chemicals has been carried out for quite a long time because the price of batik materials continues to increase. In fact, if the industrial waste is not handled properly, it can pollute the river. This shows that some batik industry perpetrators do not yet have a full level of awareness and responsibility for the output of batik making. Therefore, comprehensive research is needed on toxic and hazardous waste management in order to determine the perception of craftsmen towards toxic and hazardous waste and increase the awareness of craftsmen towards toxic and hazardous waste. Based on research conducted at Afina Batik using a combination of quantitative and qualitative approaches, information was obtained that some craftsmen did not know the types and dangers of chemical waste produced. In fact, there are chemicals used in the coloring process, such as napthol and chrome soga, which pose a risk of danger.

Abstract

Energy problems in Indonesia are issues that are not easy to solve. If the energy needs dominated by BBM continue to increase without any changes in the pattern of energy use, then Indonesia's sustainability and energy security will be disrupted. Therefore, Indonesia really needs alternative energy. Biogas is an alternative energy produced from the anaerobic degradation of organic compounds and can be a substitute for natural gas and fossil fuels. Solid tea waste can be used as a substrate from anaerobic co-digestion biogas production with cow dung. In general, the purpose of this study is to produce biogas from tea pulp and cow manure by anaerobic co-digestion and have a specific purpose, namely (i) Assessing the effect of pretreatment on the yield of biogas produced, (ii) Assessing the effect of pH on yield of biogas, (ii) Assessing the effect of the value of the C / N ratio on the yield of the biogas produced. This research was conducted by making variations in treatment including physical pretreatment with and without grinding (± 1 mm), biological pretreatment with and without addition of 5% v / v microbial consortium, pH controlled (addition of buffer) and uncontrolled, and ratio of C: N waste solid tea (25 and 30). The biogas formation process is carried out for 2 months at room temperature with the quantitative response test results in the form of biogas volume every 2 days. Biogas production in pretreatment tea grounds gives better results than without pretreatment. Optimum biogas production is obtained at a C: N 30 ratio. Comparison of C: N substrate will affect the growth of microorganisms, the microbes that play an anaerobic process need nutrients to grow and develop, in the form of carbon and nitrogen. The highest biogas accumulation produced was 73,167 ml / gr TS on variable C / N 30 ratio, NaOH pretreatment, microbial consortium and smooth size of tea waste that used.

Energy problems in Indonesia are issues that are not easy to solve. If the energy needs dominated by BBM continue to increase without any changes in the pattern of energy use, then Indonesia's sustainability and energy security will be disrupted. Therefore, Indonesia really needs alternative energy. Biogas is an alternative energy produced from the anaerobic degradation of organic compounds and can be a substitute for natural gas and fossil fuels. Cow's blood which is a waste from slaughterhouses can be used as a substrate for anaerobic biogas production by rumen and molasses. The objectives of this study are (i) To examine the comparison of the concentration of blood and molasses added to the volume of biogas produced, (ii) To examine the effect of pasteurization on blood on the volume of biogas produced, (iii) To examine the effect of initial system pH regulation on the volume of biogas produced, (iv) Assessing the pH setting and without adjusting the pH after measuring the volume of biogas produced. This research was conducted by making variations in the composition of feeds, pH stabilization, and blood pasteurization. The process of biogas formation is carried out for 40 days at room temperature with the response of quantitative results in the form of biogas volume every 2 days. Biogas production in cow's blood gets the best results at C/N 30, using pH 8. Pretreatment of blood pasteurization and pH stabilization also shows the best biogas results.

Abstract

The Covid-19 virus was recorded to have been found in Indonesia since March 2, 2020. This virus is a virus that is easily contagious, so it is one of the efforts to prevent transmission by using a mask. so that everyone is required to wear a medical or non-medical mask when doing activities outside the home. Of the two types of masks that are more often used, namely the type of medical masks that are used because they are considered safer and more comfortable than non-medical masks. However, after use, the mask turns into the garbage which is classified as B3 waste. Hazardous waste has different characteristics and properties from waste in general because it is unstable, reactive, explosive, flammable, and toxic. In this case, once the mask waste is immediately disposed of without processing, the environment can be explained. Therefore, this study was conducted with the aim of knowing the effect of disposable medical waste on environmental pollution during the pandemic era in Surakarta City. The method used in this study is a questionnaire method which was conducted through online media surveys targeting people aged 17-25 years and supported by data from indexed literature studies. The results of this study indicate that out of a total of 45 respondents, the community is very aware of B3 waste (80%), knows that B3 waste is harmful to health (100%), likes disposable medical masks (58%), understands disposable medical waste including B3 waste. (82%). Meanwhile, for the management of disposable mask waste, it shows that people still store medical mask waste at home (93%), understand the proper disposal of disposable mask waste (78%), have not differentiated it from other waste (60%), have not implemented 3R (76%) ) ), cutting medical waste before disposal (78%), understanding that medical mask waste is harmful to the environment (100%).
