Judul: Validation of analytical method for tetracyclines antibiotic residues in broiler chicken meat by high performance liquid chromatography.
Abstrak: Tetracyline (TC), oxytetracycline (OTC), and chlortetracycline (CTC) are antibiotics that have been widely used by poultryman to prevent diseases in dairy broiler chicken. Overuse of these antibiotics may lead to the presence of its residues in animal products including meat. Clinic implication which are caused by the consumption of animal products contains antibiotic residues are allergy, intoxication, and spesific of antibiotic resistance. Tetracyclines residue in broiler chicken meat can be analyzed with high performance liquid chromatography (HPLC) simultaneously with photodiode array detector on wavelength of 355 and 368 nm. The meat was extracted with McIlvaine-EDTA buffer solution and trichloroacetic acid to separate its proteins then purified in SPE C18. Tetracyclines residues was further analyzed with HPLC by using C18 Bondapak column and oxalic acid 0,0025 M-acetonitrile (4:1) with flow rate 1 ml/min. The linearity test presented a correlation coefficient of 0.99969 for OTC, 0.99947 for TC, and 0.99934 for CTC. Recovery was 48-116% according to standard addition method with acceptable limit 80-120%. The limit of detection for OTC, TC, and CTC were 5.28, 5.09, and 10.52 ppb and limit of quantitation for OTC, TC, and CTC were 5.93, 5.3, and 13.52 ppb, respectively. The analysis of broiler chicken meat from Jakarta, Bekasi, and Depok showed the amount of tetracyclines residue were from 5 to 68 ppb. According to the maximum residue limit stipulated by SNI 01-6066-2000 (100 ppb), therefore, these broiler chicken meat samples were relatively safe to be consumed.

Judul: Analisis Residu Antibiotika Tetrasiklin dalam Susu Bubuk yang Diimpor melalui Pelabuhan Laut Tanjung Priok
Abstrak: Using antibiotics in dairy farm are popular for therapy or applied as a stimulant growth. However, the presence of antibiotic residue in milk causes harmful effects on consumer's health. Tetracycline is one of the antibiotic used in an effort to improve the health of livestock, especially in disease treatment. The aim of this research was to analyze tetracycline residue in imported milk powder. Sixty imported milk powder samples were collected at Tanjung Priok Sea Port. All samples were tested using enzym linked immunosorbent assay (ELISA) as a screening test and the result showed 8 out of 60 samples (13.33%) were positive of tetracycline residue. Eight samples which were positive determined by ELISA then were confirmed by high performance liquid chromatography (HPLC) method. Five of the 8 samples contained tetracycline residue in the confirmation method. Five samples contained tetracycline residue in a high concentration, which was above the maximum residue limit according to the National Standardization Agency of Indonesia.

Judul: Konsep Taman Rumah Adat Bagas Godang Berbasis Budaya Mandailing, Kabupaten Mandailing Natal, Sumatera Utara.
Abstrak: Kekayaan suatu bangsa tidak terbatas pada kekayaan sumber daya alamnya akan tetapi juga kekayaan budayanya. Taman rumah tradisional merupakan salah satu kekayaan budaya di Indonesia yang dapat menjadi identitas dari suatu budaya tersebut. Budaya Mandailing sudah dikenal sejak abad ke-14 M. Hal tersebut dibuktikan dengan penyebutan nama Mandailing di kitab Negara Kertagama, karangan Mpu Prapanca. Budaya Mandailing awalnya banyak dipengaruhi oleh kepercayaan animisme dan dinamisme yang disebut sipelebegu. Kemudian perkembangan selanjutnya budaya Mandailing bersinggungan dengan Hindu- Budha. Akan tetapi Islam membawa pengaruh yang sangat besar terhadap budaya Mandailing. Hal tersebut dibuktikan dengan adanya filosofi hombar do adat dohot ibadat yaitu adat tidak boleh bertentangan dengan agama. Dalihan Natolu merupakan konsep kekerabatan yang banyak mempengaruhi nilai-nilai kehidupan masyarakat Mandailing. Konsep Dalihan Natolu menjadi konsep dasar yang mempengaruhi pola permukiman adat Mandailing. Dalihan Natolu terdiri dari mora, anak boru, dan kahanggi. Hubungan antara ketiga komponen ini menentukan jarak antar rumah di permukiman adat. Suatu permukiman terdapat Rumah tinggal yang merupakan landmark dari berdirinya suatu permukiman. Rumah tinggal ini disebut Bagas Godang. Bagas Godang bagi masyarakat Mandailing bukan hanya sebagai rumah tinggal seorang raja atau tunggani huta. Godang bermakna sebagai rumah bagi seluruh marga di huta adat tersebut. Bagi masyarakat Mandailing raja tidak hanya berperan sebagai penguasa huta adat, akan tetapi mereka adalah orang yang dituakan yang dapat menyelesaikan berbagai masalah di permukiman adat tersebut. Komplek Bagas Godang terdiri dari Bagas Godang atau kediaman raja, Sopo Godang yaitu tempat peyimpanan instrument alat music dan musyawarah, serta biasanya memiliki Sopo Eme atau lumbung padi, serta Alaman Bolak Selangseutang merupakan halaman.
