Utilization of bintaro shells as activated carbon to reduce phosphate in laundry wastewater Martogi - Pasaribu
Journal of Environmental Engineering and Waste Management Vol 5, No 1 (2020)
Publisher : President University

Laundry wastewater is dangerous if it is immediately disposed into a river without treating it first. One of the chemicals contained in laundry wastewater is a phosphate compound. If laundry wastewater is discharged directly into the river it will increase the phosphate content as a nutrient in river water which can be dangerous for living creatures. The high nutrient in the river will cause eutrophication in the river which will adversely affect aquatic biota. One treatment that can be done is the process of adsorption with activated carbon made from bintaro fruit shells.

Key performance indicators (KPIs) comparison of food chain reactor and conventional oxidation ditch technology in industrial waste treatment Temmy Wikaningrum; Rijal Hakiki

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.

Pengembangan Strategi Bisnis Ekowisata Yang Berkelanjutan Devi Roza K. Kausar; Reny Andriyanty; Haswan Yunaz

This research was conducted to combine the potential ecological conditions with the business model of Taman Nasional Gunung Gede Pangrango (TNGGP). Objectives: The goal of this research is to recomend the ecotourism bussiness strategy that combines with principles of sustainable development in the TNGGP. The research design was descriptive and analyzed by SWOT analysis. The recomended business strategies are strictly guardhouse supervision, for climbers are not allowed to cut, burn, move ar damage the natural beauty of TNGGP enviroment, vandalism and littering prohibited, camp in predetermined place and oriented the visitor how do ecotourism properly and correctly. The strategy can be applied with maximize the efforts to prevent the natural ecology and aesthetics damage, reduce water pollution around TNGGP, improve visitor behavior and their awareness not to damage the TNGGP area, enhance the role of communities around TNGGP in order to improve community welfare.

Housewives Environmental Awareness in Household Solid Waste Management Gilbert Givano; Yunita Ismail
Journal of Environmental Engineering and Waste Management Vol 5, No 1 (2020)
Publisher : President University

Waste generation in recent years has been increasing. The main problem is in the lack of environmental awareness. Awareness can be influenced by behavior, knowledge and income. This research wants to find out whether these 3 factors have an influence to the awareness of housewives who manage their household waste that live in residential area partially and fully. Questionnaires using likert scale that have undergone validity and reliability test were distributed online using Google Form to 100 housewives. Data were analyzed using descriptive analysis and Multiple Linear Regression. Results showed that behavior and knowledge have positive significant influence toward awareness while income has no significance towards awareness on the respondents.

The Analysis of pH Performance for Equalization Detention Time Design Case Study : WWTP2 PT. Jababeka Infrastruktur Rizka Dwi Apriliani
Journal of Environmental Engineering and Waste Management Vol 5, No 1 (2020)
Publisher : President University

Abstract. PT. Jababeka Infrastruktur is a subsidiary company of PT. Jababeka Tbk., as estate manager. One of the PT. Jababeka Infrastruktur duty is manage Wastewater Treatment Plant 2 (WWTP2). The most of incoming wastewater in WWTP2 PT. Jababeka Infrastruktur is came from food industries, whereas has potential degradable to fatty acid and caused the pH tend to be low and fluctuates. pH is one of the important parameters, especially in biological wastewater treatment system as applied in WWTP2. pH value can affect the microorganism performance in decompose the pollutant compound in wastewater. pH control action is needed to make the treatment run better. Objectives: To know the primary settling tank (PST) with ̴3 hours detention time performance in equalizing wastewater pH. To develop the new equalization tank, it was provide an analysis the pH inlet performance by measuring pH of wastewater. Method and results: Statistical analysis of secondary data by comparing standard deviation value of wastewater before and after accommodated in PST also paired sample t-Test to see the performance of PST in equalizing of pH. Besides that, taken and measuring inlet wastewater pH in every one hour also adding to the previous wastewater inlet sample to determine the optimum wastewater detention time in terms of pH. Conclusion: PST was significant unit process that can be equalize the pH value. The observation of pH characteristic pattern by time showed that the optimum equalization time was 1-2 hours. This result can be as reference to more utilize of the existing PST.
