Perencanaan Instalasi Pengolahan Limbah Cair Rumah Sakit Aliyah 3 Kota Kendari

The purpose of this study was to determine the amount of liquid waste discharge at the hospital. Data from the number of hospital patient beds is 54 beds, so the activities taking place in Aliyah Hospital 3 in Kendari city produces a maximum discharge of liquid waste of 3.78/day. The form and design of processing liquid waste which is a rectangle with anaerobic- aerobic bio filter treatment system. Liquid waste processing with anaerobic-aerobic bio filter process consists of several parts namely the oil separator tank, equalization tank, early settling tank, anaerobic bio filter tank, aerobic bio filter tank, final settling tank and equipped with a chlorinated contractor tub. As for the size of each tank, which is like an oil separator tank (0,9 m × 0,5 m × 0,7 m), equalization tank (2,6 m × 1,3 m × 1,1 m), early settling tank (1,6 m × 0,8 m × 0,9 m), anaerobic bio filter tank (2,5 m × 1,3 m × 1,4 m), aerobic bio filter tank (1,8 m × 1 m × 1 m), final settling tank (1,8 m × 0,7 m × 0,7 m) and chlorinated tank (0,6 m × 0,3 m × 0,4 m). This process system was chosen because it is in accordance with the amount of liquid waste treatment system is safe, inexpensive and easy to operate.

Evaluasi Teknik Operasional dari Kinerja Instalasi Pengolahan Lumpur Tinja di Kota Kendari

Fecal waste requires treatment (IPLT) that contains pollutant compounds which result in creating damage to the environment or potentially creating pollution. Therefore, we need a performance evaluation to optimize the performance of the Kendari City IPLT. The Kendari City IPLT serves processing of sewage sludge throughout the sub-district with sources from domestic waste processing units and facilities. Sludge desludging is only carried out by 3% of the total septic tank units that must be vacuumed. The purpose of this study is to determine the effectiveness of the performance of the IPLT in treating waste and determine whether the effluent generated from the IPLT has met the specified quality standards. This research method is to compare the effectiveness of Kendari City IPLT conditions with LH Regulation No. 05 of 2014. The BOD content after analysis was 125.1 mg/L and the oil content was 1 mg / l. The Kendari City IPLT treatment unit consisting of an imhoff tank, anaerobic pool, facultative pool and maturation pool in good condition some ponds did not meet the criteria according to the Ministry of Public Works in 1998. The imhoff tank was only 3.7 m (criteria 6-9 m), the anaerobic pool caused odor that can interfere, facultative pool water height of 2.0 m (criteria 1.2 - 2.4 m).

Pemanfaatan Kulit Buah Kakao sebagai Media Adsorpsi Logam Besi (Fe) dan Mangan (Mn) pada Air Sumur

This study aims to determine the percentage reduction in iron (Fe2+) and manganese (Mn2+) content in well water using carbon from cocoa peel as an adsorption media with media height variation. The results of this study indicate that well water sample contains iron (Fe2+) levels of 1.39 mg/L and manganese (Mn2+) of 0.76 mg/L. After filtration with 60 minutes contact using carbon of cocoa peel as an adsorption media without activation, iron content and manganese content in well water decreased. The percentage reduction of iron (Fe2+) content in media height 70 cm, 80 cm and 90 cm were 76.98%, 84.17% and 98.21%. Meanwhile, the percentage in manganese (Mn2+) content at 70 cm media height was 98,93% and archived an optimum reduction at 80 cm and 90 cm media height which is 99.79% with 60 minute contact time.

Analisis Pencemaran Logam Berat Timbal (Pb) dan Zinc (Zn) di Perairan PPS Kendari

The maintenance of fishing vessels at Perikanan Samudera Kendari Harbor (PPS) is often carried out by fishing vessels maintenance ventures such as painting, cutting, annihilating, welding, spraying by using sand, changing oils, repairing machines, and other maintenance duties. This industry could potentially lead to degradation of environmental quality, one of which is heavy metal contamination. Therefore, the purpose of this study is to know the degree of heavy metal contamination at PPS Kendari, based on physics parameters (water brightness) and chemical parameters (Pb and Zn). Lead content (Pb) at the first station (1), the second station (2) and the third station (3) was undetected. Meanwhile, zinc content (Zn) at the first station (1) and the second station (2) was also undetected. At the third station (3), the zinc content was detected of 0.006 mg/L. This value is still under standard quality, namely of 0.1 mg/L. Zn contamination index was 0.053. This value is still within 0 ≤ Pij ≤ 1,0 range which meant the content of Zn at PPS Kendari still meets the standard quality (good condition).

Perencanaan Desain Instalasi Pengolahan Air Limbah dengan Metode Biofilter Anaerob – Aerob

Planning design of wastewater treatment plant in a market is needed to improve the quality of water that will be discharged so it doesn’t pollute the environment and the near. The goal of this study is to determine the discharge of wastewater will be treated and the design of treatment basin in the wet lods area of Mandonga Traditional Market. Result of wastewater is 7.88 m3/day with a waste concentration of pH 7, BOD 64.2 mg/day, and TSS 2.130 mg/day. Wet Lods Wastewater Treatment Plant in Mandonga Traditional Market has 6 compartments such as a control tub with the fine filter addition which has a volume of 0.072 m3/day, the initial settling tank has a volume of 1 m3/day, anaerobic biofilter has a volume of 1.83 m3/day, aerobic tubs have a volume of 0.42 m3/day, the final settling tank I has a volume of 1.1 m3/day and the final settling tub II has a volume of 1.1 m3/day.
