Abstract

Batik and textile production produces liquid waste with a COD content above the environmental quality standard between 2,000-12,000 ppm. Efforts to reduce the value of COD are helped by the addition of NaOCl. This study aims to determine the pH and dose of NaOCl against COD reduction. Textile liquid waste used came from factory X while batik liquid waste came from factory Y; both factories are located in South Tangerang. In this study, the pH range, 5, 7, and 9 and NaOCl concentrations were added in 3000, 4000, and 5000 ppm. The study begins with the measurement of the actual COD value in the two wastewater. The best results for batik waste were obtained at pH 5 with the addition of 4000 ppm NaOCl which resulted in a decrease of 93%. Textile liquid waste shows the best results at pH 5 with an additional 5000 ppm NaOCl concentration which can reduce COD by 95%. The final result of the COD value has met the quality standard set by the government which is less than 250 ppm.

Abstract

The increased industrial development can cause pollution and environmental damage. Iron metal (Fe) is an essential metal whose existence is a certain amount needed by living organisms, but in excessive amounts will cause toxic effects. To overcome this problem, an environmentally friendly technology is needed, namely phytoremediation technology using kiambang plants (Salvinia molesta M) and Kayu apu plants (Pistia stratiotes L). The purpose of this study was to determine the efficiency of reducing the concentration of iron (Fe) in ground water using a combination of kiambang (Salvinia molesta M) and a combination of Kayu apu plants (Pistia stratiotes L). This research method is experimental and the research approach used is qualitative analysis. The process of phytoremediation with a batch system using a Kiambang plant (Salvinia molesta M) and wooden apu (Pistia stratiotes L) as much as 300 grams (uses a variation of the amount different from the same weight (25:75) (150:150) (75:25)) in each reactor. The results showed a decline on the 12th day. In the reactor treatment group of 1 is 0.30 mg/l and efficiency at 47%, reactor 2 is 0.06 mg/l and efficiency of 93%, and reactor 3 is 0.49 mg/l and efficiency of 9%. The highest efficiency value in decreasing the concentration of iron (Fe) in groundwater using variations in the combination of Kiambang plant (Salvinia molesta M) and the wooded plant (Pistia stratiotes L) in the reactor treatment group 2 is 93% on the 12th day.

Abstract

Zn merupakan logam berat yang banyak digunakan untuk memenuhi kebutuhan industri. Meningkatnya penggunaan Zn menyebabkan pencemaran air. Untuk mereduksi hasil buangan dari industri yang menghasilkan Zn dapat dilakukan dengan cara teknik fitoremediasi. Pada penelitian ini, fitoremdiasi yamg dilakukan yaitu dengan memanfaatkan tanaman Apu-Apu (Pistia stratiotes) sebagai tanaman fitoremediator. Penelitian ini dilakukan dengan tujuan untuk mengetahui efisiensi penyerapan logam berat Zn oleh tanaman Apu-Apu dengan variasi jumlah tanaman yang berbeda. Variasi jumlah tanaman yang digunakan yaitu 10 dan 15 tanaman dengan waktu tinggal selama 10 hari dan dengan konsentrasi awal 11,02 ppm. Hasil penelitian ini menunjukkan bahwa pada reaktor B memiliki efisiensi removal logam berat Zn sebesar 83,85% dan pada reaktor C memiliki efisiensi removal sebesar 79,50%.Kata Kunci: Logam Zn, Fitoremediasi, Pistia stratiotes, Sistem Batch

Abstract

Central Processing Plant (CPP) Gundih is one of the production facilities of natural gas processing Blok Gundih PT. Pertamina EP Asset 4 Cepu Field from Kedungtuban, Randublatung, and Kedunglusi structure. Main activities of CPP Gundih consist production and operational activities. Production activities produces produced water. The water treatment of produced water processed by a production system and process. Operational activities of CPP Gundih produces wastewater from domestic activities (office) by 161 workers/day. The quantity of domestic wastewater are 21,896 m3/day, and the quality of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solid (TSS) are 9,8 mg/L, 100 mg/L, and 33 mg/L. Grey water and black water currently accommodated in septic tanks. Runoff from the septic tank flowed through drainage without treatment. Therefore, sewerage treatment plant planned with anaerobic-aerobic biofilter. The cost needed for the construction are Rp. 13.590.441,80-.

Abstract

The waste problem is a big problem all over the world. Every year the use of plastic has increased quite high. This increase is based on changes in living conditions and development of activities. With the accumulation of plastic waste, it will have a bad impact on the environment. To overcome this problem, this research will recycle plastic waste as a mixture of construction materials. This study aims to determine the use of PET plastic bottle waste materials to substitute fine aggregate on the compressive strength and water absorption test. The experimental method is used in research by observing and testing carried out in the laboratory using 12 test objects, using SNI to plan the concrete mixture. The results showed that the compressive strength test value was 0% 24.85 MPa, 3% 8.42 MPa, 6% 4.79 MPa, and 9% 2.56 MPa. And the results of the water absorption test resulted in an average of 0% of 0.39%, 3% produced 2.46%, 6% produced 3.38% and 9% produced 4.10%.

Abstract

The application of a simple geometric concept to design a domestic wastewater treatment plant (WTP) is important because it refers to a three-dimensional spatial structure to construct a storage tank. Thus in this study, we apply a simple geometric system for the design of the reservoir design which can be applied in several simple housing areas (Perumahan Mutiara Sartika-Kendari City). The results show that with the need for clean water consumption of 150 L/day/person with 68 housing types 36 and 5 people/house, the amount of waste generated is 40.8 m3/day. So that the dimensions of the wastewater reservoir built are rectangular with a total volume of 79.1 m3 with an estimated residence time of 29 hours taking into account several functions of the treatment unit. Based on the results of this study, it is hoped that it can help to apply a simple WTP design for housing development.

Abstract

Geographical location owned by Situbondo Regency has a coastal area, which could have the potential for sea water intrusion. Therefore, this study aims to explore water resources, namely groundwater in a coastal area of ​​Situbondo Regency - Banyuwangi Regency, which can be used to see the feasibility of life, especially for humans and animals. This research was conducted by sampling groundwater or well water using 3 parameters, namely TDS, pH, and salinity. After measuring the air content using TDS and pH parameters, ground or well water content, it is still suitable for use with a value range of 746 to 1170 mg/L for TDS, and 6.27 to 7.91 for pH content. Meanwhile, the salinity parameter can deny that the area measured in the study experienced sea water intrusion, but the value is not too high, namely 2 to 4 ‰. Then, for future improvements, it is necessary to carry out further research along the road from Situbondo District - Banyuwangi Regency to obtain a broader picture.
