ABSTRACT
This study aims to obtain empirical data, and reliable information about the effectiveness of rehabilitation and development patterns of the drug addict at the Center for Rehabilitation of the National Narcotics Agency Indonesia-Lido, Bogor. The method used is descriptive qualitative. The pattern of development in the institution more emphasis on behavior change, by conducting medical rehabilitation and social rehabilitation. Rehabilitation is divided into two major phases, namely the phase of medical rehabilitation and social rehabilitation phase. Medical rehabilitation includes detoxification and entry. While social rehabilitation phase includes primary phase and re-entry phase. Rehabilitation and development patterns are effective against drug addicts. This can be seen with the recovery rate of the resident and the resident's rate of return using drugs. But it is also influenced by many factors, both internal and external.
Keywords: Rehabilitation, patteration, drug addicts.
In this research Xanthosoma nigrum Stellfeld (the Purple yam) was selected as experimental material. This plant was collected from Rejang Lebong region, Bengkulu Province. Methanol extract 96% from stem of purple yam was studied its anti-oxidant activity in various concentrations with α-tocopherol (200 ppm) as standard of antioxidant. Antioxidant activity was determined using Thiobarbituric Acid (TBA) method. Linoleic acid was oxidized at 40 ºC for seven days with or without extract and the final product malondialdehyde (MDA) was reacted with thiostembituric acid to be of red colored complex (MDA-TBA) and was then measured by UV-VIS spectrophotometer at λ 532 nm. Stem extract of purple yam with concentration of 100 ppm, 150 ppm, 200 ppm and 300 ppm respectively had the inhibition of 19.32%, 21.85%, 29.47%, and 31.05%. α-Tocopherol as positive control which showed inhibition ability of 85.14% at 200 ppm. Based on the result obtained in this study, the stem's extract of Purpel yam plant showed that antioxidant activity was lower than α-tocopherol.
Sungai Kelingi diperkirakan telah mengalami tekanan dari lingkungan dan penurunan kualitas air, sehingga perlu dilakukan perhitungan dan mengidentifikasi kualitas Air Sungai. Pengambilan sampel dari hulu sampai kehilir Sungai Kelingi. Waktu penelitian dilaksanakan selama kurang lebih 4 bulan, dimulai dari bulan Januari sampai dengan April 2018. Hasil penelitian dan perhitungan status mutu air Sungai Kelingi yang telah dilakukan di 5 (lima) titik pengambilan sampel untuk 8 (delapan) parameter yaitu Suhu, TDS, TSS, pH, COD, BOD, Timbal dan Fecal Coliform yang dilaksanakan pada 08 Maret 2018 dapat disimpulkan bahwa; Status mutu air Sungai Kelingi jika di analisa dengan menggunakan metode STORET menunjukan bahwa Sungai Kelingi tergolong dalam kelas A (baik sekali) atau memenuhi baku mutu di semua titik pengambilan sampel. Pada perhitungan mengunakan metode Indeks Pencemaran (IP) menunjukan tercemar ringan pada titik 1,2 dan 5. Evaluasi status mutu air Sungai Kelingi dengan menggunakan metode Indeks Pencemaran (IP) tahun 2015 status mutu air Sungai Kelingi pada bagian hulu PIj sebesar 0,53 tergolong memenuhi baku mutu dan pada bagian hilir PIj sebesar 0,86 tergolong memenuhi baku mutu, tahun 2016 status mutu air Sungai Kelingi pada bagian hulu PIj sebesar 0,67 tergolong memenuhi baku mutu dan pada bagian hilir PIj sebesar 1,26 tergolong dalam cemar ringan, tahun 2017 status mutu air Sungai Kelingi pada bagian hulu PIj sebesar 1,31 tergolong dalam cemar ringan, pada bagian tengah PIj sebesar 1,59 tergolong dalam cemar ringan dan pada bagian hilir PIj sebesar 1,86 tergolong dalam cemar ringan.Kata Kunci: Sungai, Kelingi, Kualitas Air, STORET dan Indeks Pencemaran
