Sidomulyo Village, a flower tourist village, in Batu city is one tourist destination in East Java Province based on local wisdom as an icon of Agro-industrial and Agro-tourism in the development of regional tourism. The local products from Sidomulyo Tourism Village include ornamental plants, cut flowers and batik. Sidomulyo Batik UKM is a batik producer with a capacity of 20 sheets per month @ 2.25 m2 and uses manual coloring technology. So far, UKM Batik Sidomulyo has been doing the coloring process in partnership with UKM Batik in Banyuwangi and Trenggalek Regencies due to technological limitations in the processing of batik liquid waste which still contains hazardous and toxic materials so if no action is taken it can damage the ecosystem. One of the strategic solutions is the technology transfer of the mini Wastewater Treatment Plant (WWTP) which utilizes biological waste treatment technology by utilizing bacteria and facilities that are Proven Technology. The mini WWTP installation uses 3 processing rooms including (1) separation of wax content from liquid waste, stirring with coagulant treatment to separate liquid waste from B3 waste and (3) purification of liquid waste by treating biofilter media and anaerobic bacteria. The levels of BOD and COD of the waste will be measured before and after the use of the mini WWTP so that it will be environmentally friendly without reducing the quality of batik as a support for souvenir products typical of Sidomulyo Tourism Village.

Industri minyak sawit mempunyai impak yang besar ke atas alam sekitar. Efluen kilang minyak sawit (dikenali juga sebagai palm oil mill effluent, POME) merupakan buangan cecair yang terdiri daripada sebatian organik yang berasal daripada bahan bolehurai dan sedia direput oleh miroorganisma aerobik dan juga anarobik. Teknologi rawatan POME masa kini banyak bertumpu kepada kaedah biologis. Proses–proses ini memerlukan keluasan tanah yang besar dan tidak menjamin pencapaian had discas yang dibenarkan[1]. Kertas ini menghuraikan satu kajian mengenai potensi kegunaan teknologi membran untuk merawat POME dari kolam discas terakhir. Bahagian pertama kajian ini meneliti ciri–ciri beberapa kolam yang terdapat di loji rawatan air sisa POME yang sedia ada. Kajian membran pula melibatkan penggunaan membran gentian kosong dengan MWCO berjulat 30K hingga 100K. Data yang diperolehi menunjukkan bahawa membran yang mempunyai MWCO 100K menghasilkan fluks yang lebih tinggi daripada membran MWCO 30K, tetapi membran MWCO 30K memberi permeat yang kualitinya lebih baik. Kualiti permeat hasil daripada membran di atas berjaya menurunkan COD, SS, TKN dan nitrogen–amonia masing–masing sebanyak 97.66%, 98%, 53.85% dan 61.91%. Tetapi pemindahan warna memerlukan rawatan tambahan. Kata kunci: Membran, penurasan-ultra, POME, rawatan sisa The palm oil industry has a significant impact on the environment. Palm oil mill effluent (POME), which is the liquid discharge, comprises of mainly organic compounds originating from biodegradable materials and is readily decomposed by anaerobic, and aerobic microorganisms. The current treatment technology of POME is largely biological in nature. These processes require large acreage of land and do not always achieve the discharge limits [1]. This paper describes a study on the potential use of membrane technology to treat POME from the final discharge pond. The first part of the study investigated the establishment of characteristics of the various ponds within the current POME wastewater treatment plant. The membrane study essentially used hollow fiber membrane of MWCO ranging from 30 to 100K. The results showed that the hollow fiber membrane with MWCO 100K gave higher fluxes compared to the MWCO 30K, however, the latter membrane gave better quality permeate. The quality of permeate achieved from the membrane with MWCO 30K gave reductions in COD, SS, TKN and ammoniacal–N of 97.66 %, 98 %, 53.85 % and 61.91 % respectively. However, color removal may require further treatment. Key words: Membrane, ultrfiltration, POME, waste treatment

Organic Waste Treatment

The municipal solid wet waste is an organic fraction that contributes to around 40% of total waste and it is biodegradable. In the present scenario, wet waste is generally mixed with other kinds of waste that is not bio-degradable. The foul smell is generated from the wet waste if not disposed within 24 hrs. This smell creates problem for people exposed to handling and management system. All biological treatment technologies applied to the wet (organic) waste treatment would require segregation of biodegradable and non-bio-degradable components. Once the waste of different categories is mixed it becomes very difficult to segregate them effectively. Many large size plants in the country are constructed to treat biodegradable waste with the objective to recover energy and produce organic manure but its smooth operation faces great challenge of accurate segregation resulting into plant break down and failures irrespective of robust technology. This research paper focuses on unique approach of public participation for segregation at source by deploying micro level biological treatment plants of capacity ranging from 1.0 MT/d to 5 MT/d. With the implementation of above approach and treatment technology, huge efforts that are presently put to segregate the waste will be eliminated. In addition to this, the energy and organic manure as end product obtained from the treatment plant makes it as self-sustainable.

Abstract Background:The study conducted a comprehensive assessment of the quality of selected groundwater sources around the liquid waste treatment plant of Ahmadu University Teaching Hospital Shika, Nigeria. Water samples were collected from four (4) hand-dug wells following standard procedures, ten (10) physicochemical parameters and seven (7) heavy metals were analyzed.Results: All the physicochemical parameters studied were within the WHO specified limits except for DO which was less and turbidity which was higher. Heavy metals were found in the all the groundwater sources that were studied. However, the concentration of some heavy metals exceeded the specified limits recommended by the World Health Organization (WHO). The heavy metal presence in the groundwater sources may be connected to human activities such as waste disposal containing these metals around the groundwater sources and liquid waste from the hospital which can may have seeped into the wells.Conclusion: By implication, this study shows that the hand-dug wells were not safe for drinking. It is recommended that wells be sited away from dumpsites and waste treatment plants and effluents from waste treatment plants should also be properly treated before their subsequent discharge into the environment. This study has generated a baseline data that will be useful in monitoring heavy metal pollution.

Home Industry Tofu X Established in 2002 and this business has existed from generation to generation until now. Tofu is a food made from fermented soybeans and extracted the juice. In general, the process of making tofu includes soaking soybeans for several hours, milling soybeans, boiling the results of milled soybeans, filtering, clumping soybean slurry using vinegar, molding and cutting. In the tofu industrial wastewater, there are organic materials in the form of 40-60% protein, 25-50% carbohydrates and 10% fat. If it is increasing, the volume will increase. The purpose of this study is to determine the Environmental and Health Impact Analysis of the Affected Areas of Tofu Liquid Waste in the Home Industry Tofu X Pangkalan Kerinci Barat Urban Village in 2020. This type of research is qualitative analytic by conducting in-depth interviews and direct observation. as well as laboratory tests for parameters BOD, COD and DO. The result of this research is that the waste treatment process has not been implemented in accordance with KepMenLH No. 51 of 1995 concerning the quality standard of liquid waste for tofu home industry. So that the resulting tofu wastewater is discharged directly into the pipelines leading to the river with BOD, COD and DO content which have not met the water quality standards set by the government PP No. 82 of 2001 and causing the river to be polluted, emitting a pungent odor and disturbing the comfort of the surrounding community. So a wastewater treatment plant (IPAL) is needed to treat water before it is discharged into the waters.

Biosorption is a new waste treatment technology that can eliminate toxic heavy metals. Biosorption can be considered as an environmentally friendly alternative technology to treat industrial liquid waste that is economically proper to use. One of them is biosorption that utilizes the microorganisms’ absorption ability, especially bacteria that can absorb heavy metals in waters, such as Enterobacter agglomerans. This research aimed to determine the ability of E. agglomerans in reducing heavy metals pollution in local river. The research employed the measurement of the effect of lead (Pb) to E. agglomerans growth using Optical Density (OD) at wavelength 600 nm. The colony numbers were calculated using a standard curve. While the ability of E. agglomerans to reduce heavy metals concentration in liquid media was measured using AAS with a wavelength of 240 nm. The results showed that lead affected the growth of E. agglomerans. The OD value has a negative relationship with the concentration level of Pb. The ODs were decreased from 2.867 to 1.242, using Pb level from 0 ppm to 20 ppm. Therefore, it proved that E. agglomerans could reduce heavy metals concentration in local river in Central Java Province. This research was the first report on E. agglomerans activity on heavy metal in contaminated water. This result can be used as a reference for industrial sites near the river to treat their wastewater before discharging it to the river body to preserve its water purity.
