Judul: Evaluasi Penerapan Sistem Pemotongan Ditinjau dari Keamanan dan Kehalalan Daging pada Tempat Pemotongan Kambing di kota Jambi
Abstrak: Food of animal origin such as a meat, milk, egg and processed product are perishable and potentially for biological hazard, chemical, and physical known as Potentially Hazardous Food (PHF). Hence, handling of this product must be good and true. There are several steps that determine the quality and safety of meat in their supply chain, one of which is the stage of salughtering in slaughterplaces. The objective of this study to evaluate the application of slaughtering (Good Salughtering Practice), Halal Assurance System (HAS), and meat safety at goat slaughterplaces in Jambi city that term of microbiological contamination, heavy metals contamination and organofosfat pesticide residues. The study used a descriptive, randomized sampling of livestock numbers slaughtered at slaughterplaces in Jambi city. Evaluation of physical quality of the meat (pH, color, and water holding capacity), microbial contamination (TPC, E.coli, coliform, Salmonella sp, and Staphylococcus) contamination of heavy metals (Pb, Cd, and Hg) and pesticide residues organofosphat. The sample used for the analysis of physical and microbial contamination is the leg, whereas the sample used for the analysis of heavy metals and pesticide residues are leg, liver and kidney. The GSP implementations at all of slaugtherplaces in Jambi city has not been done to maximum. This is proved from ten assessment characters of East Jambi, Telanaipura, and Jambi Market Slaugtherplaces can be able to meet 58.00%, 57.50%, 58.00% respectively. SJH parameters were evaluated largely unmet. East Jambi, Telanaipura, and Jambi Market Slaugtherplaces was carry of SJH by 47.50%, 49%, 45.50% respectively. The value of meat goats pH is still within the range of normal meat pH (5.75 and 5.92) at all of goat slaughterplaces. The Water Holding Capacity (WHC) on ranges (37.58% - 42.56%) and color of meat goats on ranges (6.5 - 7.5) are included in the Quality II with dark red color. Microbiological contamination, especially E. coli and coliform in meat goats was exceed the maximum limit according to Indonesian National Standard 3925: 2008. E. coli exceeded the maximum found at East Jambi and Telanaipura Goat Slaughterplaces. Coliform exceeded the maximum limit found at all of goat slaughterplaces. The meat, liver and kidney goats in Jambi city showed undetectable residues of heavy metals, but the meat and kidney goats contaminated by organophosphate pesticide residues of dikhlorfos and profenofos groups. All of samples that positive were contaminated demonstrate the value of which does not exceed the maximum limit determined by Indonesian National Standard 7317:2008 about contamination limits organophosphate pesticide residue groups are 0.05 ppm.

Judul: Evaluasi Penerapan Sanitasi, Sistem Pemotongan, Sistem Jaminan Halal dan Keamanan Daging Sapi di RPH Kota Pekanbaru
Abstrak: Penyediaan bahan pangan dengan nilai gizi tinggi merupakan masalah penting sebagai upaya meningkatkan kesehatan dan kecerdasan masyarakat. Salah satu bahan pangan yang mengandung nilai gizi tinggi adalah daging sapi. Pemenuhan kebutuhan masyarakat akan daging perlu dilakukan dengan cara meningkatkan produksi dan kualitas hasil ternak secara optimal serta menjamin mutu daging yang aman sampai ke konsumen. Peningkatan permintaan daging tidak selalu diikuti dengan perbaikan sarana rumah potong hewan (RPH) yang memadai, sehingga keamanan dan kehalalan daging menjadi suatu permasalahan yang belum terselesaikan. Kualitas dan keamanan daging yang dihasilkan salah satunya ditentukan oleh pelaksanaan penyediaan daging di rumah potong hewan (RPH). Proses penanganan ternak dan daging di RPH yang kurang baik dan tidak memperhatikan faktor-faktor sanitasi dan higienis, akan berdampak pada mutu, kehalalan dan keamanan daging yang dihasilkan. Selain itu, diperlukan penetapan aturan atau standar operasional maupun teknis sebagai dasar untuk menyelenggarakan fungsi RPH sebagai tempat pelaksanaan pemotongan ternak guna menghasilkan daging yang ASUH (aman, sehat, utuh dan halal). Penelitian ini bertujuan untuk mengevaluasi penerapan standard sanitation operational procedure (SSOP), good slaughtering practices (GSP) dan sistem jaminan halal (SJH) serta nilai kontrol veteriner (NKV) terhadap rumah potong hewan (RPH) Kota Pekanbaru. Selain itu, penelitian ini bertujuan mengevaluasi keamanan daging asal RPH Kota Pekanbaru ditinjau dari kualitas daging yang meliputi mutu fisik, tingkat cemaran mikroba, cemaran residu logam berat (Pb, Cd, Hg) serta cemaran residu pestisida golongan organofosfat. Pengambilan sampel dilakukan secara acak sederhana (simple random sample) terhadap sejumlah pemilik ternak yang melakukan pemotongan di RPH Kota Pekanbaru. Sejumlah pemilik ternak, diambil lima pemilik ternak yang melaksanakan pemotongan di RPH sebagai sampel pengamatan SSOP, GSP, SJH dan NKV. Tiga ekor ternak diambil dari masing-masing pemilik ternak untuk dianalisis mutu fisik daging (pH, warna, persentase air bebas), cemaran mikroba (Salmonella, Eschericia coli, Coliform dan total plate count/TPC), cemaran residu logam (Pb, Cd dan Hg) serta cemaran residu pestisida organofosfat. Sampel yang dianalisis berupa sampel daging sapi bagian otot Bicep femoris (BF) dan Longissimus dorsi et lumbarum (LD), organ hati dan ginjal...dst

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
