Judul: Analysis of Blood Draining Level on Layer Chicken Wings Colorimetry Based by Digital Image Processing
Abstrak: Ayam layer afkir biasanya banyak dijual terutama menjelang hari raya. Banyaknya penjualan ayam layer afkir dilakukan dalam rangka memenuhi tingginya permintaan masyarakat terhadap daging ayam. Konsumsi daging ayam terus meningkat setiap waktunya namun tidak sebanding dengan peningkatan kualitasnya. Tujuan penelitian ini yaitu mengukur konsentrasi darah pada daging sayap ayam layer afkir serta membandingkan kemampuan pemindai dan kamera ponsel dengan spektrofotometer berdasarkan prinsip kolorimetri. Daging sayap ayam sebanyak 40 sampel sayap kiri dan kanan dipotong kecil-kecil untuk dibuat ekstrak. Ekstrak daging yang telah direaksikan dengan malachite green kemudian ditambahkan KMnO4 kemudian diuji menggunakan spektrofotometer dan pemindaian menggunakan pemindai dan kamera ponsel. Hasil pemindaian kemudian diolah dengan menggunakan aplikasi ImageJ. Nilai konsentrasi darah diolah menggunakan SPSS. Hasil menunjukkan bahwa konsentrasi darah yang diukur menggunakan spektrofotometer, pemindai dan kamera ponsel pada daging sayap ayam layer afkir yang disembelih dengan proses penggantungan memiliki perbedaan yang nyata (P<0,05) dengan daging ayam yang disembelih tanpa proses penggantungan. Nilai koefisien korelasi antara spektrofotometer dengan pemindai dan kamera ponsel masing-masing adalah 0,95 dan 0,98. Berdasarkan hasil tersebut, dapat disimpulkan bahwa pemindai dan kamera ponsel memiliki potensi sebagai alat alternatif untuk mengukur konsentrasi darah pada daging ayam layer., Culled layer chicken is usually sold, especially before the feast days. The number of sales of culled layer chickens is carried out in order to supply the high public demand for chicken meat. Consumption of chicken meat continues to increase every time but is not comparable with the increase in quality. The purpose of this study was to measure blood concentrations in layer chicken wing meat and to compare the capabilities of scanner and mobile camera to spectrophotometer based on colorimetric principles. 40 samples of left and right wings were cut into small pieces for extract. The meat extract that had been reacted with malachite green was then added with KMnO4 and then tested using spectrophotometer and scanning using scanner and mobile camera. The scan results are then processed using the ImageJ application. Blood concentration values were processed using SPSS. The results showed that the blood concentration measured using spectrophotometer, scanner and mobile camera on chicken wing meat slaughtered by the hanging process had a significant difference (P <0.05) with chicken meat slaughtered without hanging. The correlation coefficient values between spectrophotometer with scanner and mobile camera were 0,95 and 0,98 respectively. According to the results, it can be concluded that scanner and mobile camera have the potential as an alternative tools for measuring blood concentrations in layer chicken meat.

Judul: Digital Image Processing for the Analysis of Completeness Bleeding Process of Femoral Layer Based on Colorimetry
Abstrak: Kasus penjualan daging ayam bangkai atau dengan proses pemotongan yang tidak sempurna sangat merugikan masyarakat karena keberadaan darah dalam daging menyebabkan kualitas karkas menurun dan daging cepat membusuk. Hal ini mengakibatkan aspek keamanan dan kehalalan daging menjadi tidak terjamin. Penelitian ini bertujuan menganalisis penggunaan pengolahan citra digital yang dibandingkan dengan alat spektrofotometer dalam mengukur konsentrasi darah pada daging ayam layer dengan perlakuan yang berbeda. Ekstrak sampel daging direaksikan dengan malachite green dan H2O2 diuji menggunakan spektrofotometer, scanner dan kamera telepon genggam. Hasil gambar diolah menggunakan ImageJ dan dianalisis menggunakan uji T pada aplikasi SPSS. Konsentrasi darah dalam daging ayam dengan perlakuan sembelih tanpa digantung lebih tinggi dibandingkan dengan perlakuan sembelih digantung. Ini juga menunjukkan hasil yang signifikan (P<0,05) baik diukur dengan menggunakan spektrofotometer maupun scanner dan kamera telepon genggam. Uji korelasi spektrofotometer A–spektrofotometer B, spektrofotometer A-scanner dan spektrofotometer A-kamera telepon genggam terhadap larutan standar yaitu 0,9972; 0,9757 dan 0,9702 yang menunjukkan adanya hubungan erat. Berdasarkan hasil tersebut scanner dan kamera telepon genggam dapat digunakan sebagai alat pengolahan citra digital dalam menganalisis kesempurnaan pengeluaran darah., The case of the sale of chicken carcasses or with imperfect slaughtering process is very detrimental for the community because the blood existence in the meat causing the decrease quality of carcasses and the meat quickly to rot. These aspects affect to safety and halal meat become unsecured. The study aimed to analyze the use of digital image processing compared with spectrophotometer in measuring the blood concentration on chicken meat layer with different treatments. Meat sample extracts reacted with malachite green and H2O2 were analyzed using spectrophotometer, scanner and mobile phone camera. The images were processed using ImageJ and analyzed using T test in SPSS application. The concentration of blood in chicken meat with non hanging slaughter treatment is higher than a hanged one. It is also indicated the significant result (P<0,05) both measured using spectrophotometer as well as scanner and mobile phone camera. The correlation test of spectrophotometer A–spectrophotometer B, spectrophotometer A-scanner and spectrophotometer A-mobile phone camera against the standard solution was 0,9972; 0,9757 and 0,9702 which show a close relationship. Based on these results, scanner and mobile phone camera can be used as an digital image processing tools in analyzing the completeness bleeding process of blood.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
