Teknologi pengolahan air limbah khususnya untuk mengurangi konsentrasi amonia telah banyak dikembangkan, baik teknologi pengolahan secara biologi maupun kimia. Masalah teknologi tersebut pada umumnya membutuhkan biaya yang tinggi yang tidak sejalan dengan konsep keberlanjutan, apalagi menghasilkan limbah limbah B3 sebagai produk sampingannya. Untuk itu diperlukan alternatif rekayasa teknologi yang lebih berkelanjutan. Penelitian ini bertujuan untuk mengetahui potensi penggunaan eco-enzyme untuk mengurangi konsentrasi amonia dalam air limbah, sebagai alternatif teknologi rekayasa berkelanjutan. Hal ini dimungkinkan mengingat eco-enzyme terbuat dari air, bahan organik, dan gula merah atau molase , yang berarti semua bahan tidak mengandung bahan kimia dan residu berbahaya. Apalagi bahan organik yang digunakan bisa berasal dari sampah organik. Metode penelitian adalah eksperimen skala laboratorium pada sampel air buatan, menggunakan eco-enzyme yang terbuat dari kulit dan buah nanas yang telah difermentasi selama 6 bulan dengan hasil pH = 3,36 dan tidak terdeteksinya adanya amonia. Pada sampel air dengan konsentrasi amonia awal sebesar 34,5 mg/L, hasil penurunan konsentrasi amonia masing-masing sebesar 6,7%, 12,8%, 15,3% dan 25,2% pada pemberian eco-enzyme secara berturut-turut dengan konsentrasi 2%, 6%, 8% dan 10%. Pada data konsentrasi amonia yang mengalami penurunan dibandingkan dengan nilai awal, dilakukan analisis uji-t statistik menunjukkan nilai P (T<=t, two tail) sebesar 0,047 < 0,05, sehingga nilai penurunan tersebut signifikan karena kedua data tersebut berbeda nyata. Dapat disimpulkan bahwa penurunan konsentrasi amonia meningkat dengan meningkatnya konsentrasi eco-enzyme yang diberikan pada sampel air dengan linieritas 97.3 %.

Environmental management in industrial estate is the strategic policy model which is needed to be developed referring to the Indonesian Government Decree number 24 year 2009, that state almost all of the new industrial developments should be located in industrial estate. The complexity in this environmental management was approached by “green rating” of PROPER’s criteria regulated by Ministry of Environment & Forestry (KLHK). PROPER is the assessment program of company performance rating in environmental management. Green rating is classified by PROPER in terms of beyond compliance performance. The result of the case study in Jababeka Industrial Estate (KIJA) Bekasi, based on its environmental situational analysis year 2014 by multidimensional scaling (MDS) method, showed that only the management dimension had a sustainability performance. The results of prospective analysis on leverage factors of MDS showed that the key factors of the environmental management model were (1) DRKPL (summary document of environmental management performance), (2) implementation of water conservation and reducing water pollution program, (3)funding for water conservation, (4) monitoring and evaluation of community development program, (5) implementation of 3R (reduce, reuse, recycle) programs of hazardous waste, (6) technology of 3R, and (7) benchmarking. Based on the key parameters and referred to the possibilities conditions, three scenarios have been developed to approach the implementative policy. The moderate scenario was recommended to be the right policy in term of consideration of technology, funding availability, time of implementation and organization skills.Keywords: environmental management, industrial estate, jababeka, proper KLHK

Service on garbage pick-up is an obligatory service which, should be provided by the goverment. Due to human’s active mobility, which doing activities that may result in waste, that may cause bad impact on the environment and also human themselves. However, the service cost for garbage pick up is not that affaordable, in which government is required to do efficiency, especially to efficient in terms of time. In this study, the place that was used as sample is Padang City. In Padang City, the time that needed to pick-up the garbage from the time the trucks start the trip from the shelter, up to each pick-up point and drop it to the landfill site takes around 6.97 hours. This data is a secondary data that obtained by previous researchers. In this study, the time simulationhas been elaborated by replacing the conventional garbage bin to smart dust bin. Smart dustbin is equipped with sensor to count how much garbage inside it and other types of sensor are also equiped to accommodate its work. In addition, Smart Dustbin also equiped with GSM module to send information for indicating that the garbage bin has full. A simulation result showed that using smart dustbin can reducing the pick up time according to the pick-up points that informed by the GSM module.

Industrial Estate development has an important role for national economic growth. The government regulation number 24 year 2009 (replaced by number 142 year 2015) states that most of all industrial / manufacturing activities in Indonesia should be located in industrial estate. By this reason, an integrated environmental management in industrial estate will become the significant strategic to support national sustainable development. Industrial estate developer should have a proper environmental management system to minimize the negative impacts of its activities to environment. The sustainability performance analysis was conducted in Jababeka Industrial Estate, year 2008-2014, which refer to PROPER KLHK green rating criterias (the assessment program for company performance rating in environmental management issued by Ministry of Environment and Forestry). The analysis was approached by multi-dimensional scaling (MDS) with rapfish software modification. The sustainability analysis result showed that the ‘sustainable’ status was only achieved on institutional management dimension (Stress: 23.15%, R2: 94.4), while other dimensions (ecology, technology, social and economy) had the status of ‘less sustainable’ or ‘not sustainable’. The dominant leverage factors in environmental management were 3R hazardous waste implementation (RMS 8.69 > median 4.35), the financing of water conservation and wastewater reduction (RMS 4.08 > median 2.275), community development implementation (RMS 6.38 > median 5.69), air emission reduction technology (RMS 10.65 > median 2.79), and benchmarking policies (RMS 15.45 > median 12.15). By considering this dominant leverage factors, Industrial Estate Company was recommended to apply the strategic plans to achieve the sustainable performance in the near future.

Ambient Air Quality Monitoring (AAQM) must be conducted by Industrial Estate Management, according to legislation and regulation in EIA (Environmental Impact Assessment) Report. AAQ test parameter are Sulfur Dioxide (SO2), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Ozon (O3), Hidrocarbon (HC), PM10, PM2,5, Total Suspended Solid (TSP), and Lead (Pb). Industrial Estate Management has an extensive role in AAQM, analysing and organizing better environmental policies. The data of Jababeka Industrial Estate (JIE) AAQM was seized from EIA Report each semester from year 2015 to 2018 and analyzed using openair model. A review of AAQM and Management in other industrial estate was done as a lesson-learned and insight to improve the AAQM System in JIE. Openair model can analyze the AAQ data with meteorological data around the sampling point area, and visualize it through the pollution rose function. The limited data of AAQM and weather, will limitate the result and analysis. The future research must aims to make a real-time/continuous AAQM and meteorological data to get more accurate and comprehensive data modeling and analysis.

The oxidation process as the activated sludge (AS) system has been implemented widely in urban and industrial wastewater treatment. Oxidation ditch can be categorized as an advanced aeration activated sludge. Integrated Fix-Film Activated Sludge (IFAS) process has been already developed for decades that was a reasonable approach for technology to upgrade the activated sludge wastewater treatment plant (WWTP). IFAS processes are a combination of biofilm reactors and activated sludge processes, biofilm is introducing and retaining as the carrier media for microorganism growth. Both IFAS and AS processes can achieve similar percent removal of COD and ammonia. Current WWTP’s development was food chain reactor (FCR) which mainly IFAS process of engineered media that combining with natural plants with the plant roots submerging into the reactors. The references review and secondary data of the application in Jababeka’s WWTP-2 for both AS and FCR system showed that FCR is needless parameters to be controlled. In both AS and FCR have KPIs of flow rate (m3/day), F/M ratio, energy consumption (kWh/m3 wastewater), Oxygen supply (kgO2 / m3 wastewater in each reactor, % removal of COD, BOD, TSS, NH3, TKN, NO2, and heavy metals, and pH, Dissolved Oxygen, microorganism performance in the reactor. Different from AS, the FCR system is not required to control the parameters of sludge retention time (SRT), recirculated activated sludge (RAS), sludge volume index (SVI), and mixed liquor suspended solids (MLSS)of activated sludge.

Production of organic waste that is dominating waste generation becomes a problem for the environment. Eco enzyme is a solution made from brown sugar, water, and fermented fruit waste. Eco enzyme can become one of solution to reduce waste generation. Eco enzyme utilize organic waste recycling and brown sugar as the fermentor. This solution can be utilized into multipurpose cleaning liquids, eco enzyme also can reduce the wastewater contaminant, it can reduce effect of wastewater after dispose to the environment. This research has purpose on determines the characteristic of the guava eco enzyme and the correlation on the reduction of NH3, pH, and PO4 in water. The research results show that the guava eco enzyme is acidic with pH 3.36, it also containing 1.4 ppm of NH3, 11.2 ppm of PO4, and 116800 mg/l of COD. From the observation in the variation of time eco enzyme can reduce NH3 and PO4 also pH value. With 2% of guava eco enzyme concentration, it can reduce 27.5 % of NH3 with eight hours observation and 20% of PO4 contaminant in the water in 6 hours observation. From the analysis of guava eco enzyme, resulted that a higher concentration of an guava eco enzyme can reduce higher contaminant. With higher concentration of eco enzyme which 5%, 7%, and 10% it can reduce 28.3%, 30.1%, and 31% of NH3. From correlation analysis there is strong correlations between NH3 and pH reduction percentages with a concentration of eco enzyme added to the water. A small amount of guava eco enzyme also effective in reducing the pH of the water. It can reduce until 50% of pH by 2.4% eco enzyme concentration. This finding may contribute as the baseline for further improvement of household wastewater pre-treatment.
