Abstract

Among the industries in Lampung, PT. Perkebunan Nusantara VII (Persero) Bekri Business Unit is one of the Palm Oil Processing Plant (POPP) industry who spend a lot of waste water in the form of residual organic liquid materials. The rest of the liquid material can cause problems such as pollution so it needed special treatment before the waste water is discharged into the environment. This study was conducted to determine the quality of liquid waste in an anaerobic pool IV on Wastewater Treatment Plant (WWTP) PT. Plantation Nusantara VII (Persero) Business Unit Bekri so it can be determined whether the waste water treatment process can improve the quality of waste water for the better. Waste water quality measurement is done using the parameters of physics,chemistry, and heavy metals, namely pH, COD, BOD5, TSS, Cd, Cu, Pb, and Zn. The results showed that the quality of the wastewater in an anaerobic pool IV was good and meets the quality standards of palm oil mill effluent by the State Minister of Environment Resolution No. 03 / MENKLH /11/1991 and the Indonesian Government Regulation No. 20 of 1990 on Water Pollution Control. It also indicates that the effluent treatment system at the Wastewater Treatment Plant (WWTP) PT. Perkebunan Nusantara VII (Persero) Bekri Business Unit is very effective.Keywords: anaerobic pool, liquid waste, PTPN VII

Abstract

Wonosadi forest is managed forests by indigenous forest communities and is located in the hamlet of Duren and Sidorejo, Beji village, subdistrict Ngawen, Gunung Kidul regency, Yogyakarta. One of the biological richness contained in Wonosadi forest is very valuable natural orchids and need to be preserved. Management to the preservation of nature in the woods Wonosadi orchids can be done through natural orchid protection against infectious pathogens, including viruses. Odontoglossum ringspot virus (ORSV) is one type of orchid viruses infect most widely reported and has spread widely in the world, including in Indonesia. ORSV can cause severe damage to the orchid. Therefore, it is necessary to study to detect ORSV that infect wild orchids in the forest Wonosadi molecular basis for detecting the presence and pattern of infection ORSV as well as possible to reduce the severity of disease caused by infection with the virus. The purpose of this study is to assess the natural orchid ORSV infection in molecular Wonosadi forest that can be used as a database in an effort to protect against natural orchid Wonosadi forest. In the long term, the results of this study are very useful to support conservation efforts and determine appropriate conservation efforts for wild orchids in the forest Wonosadi. The initial phase of the study conducted a survey and collection of samples of wild orchids in the forest leaves that show symptoms of infection Wonosadi ORSV. Furthermore, molecular analysis performed with gene amplification Coat Protein ORSV using Reverse engineering Trancriptase Polymerase Chain Reaction (RT-PCR).Keywords: orchid soil, ORSV, RT-PCR, Wonosadi forest
