Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.
