Abstract

Abstrak: Kualitas telur merupakan karakteristik dari telur yang menentukan kesegaran dan kesehatan telur. Salah satu unsur penentuan kualitas telur adalah berdasarkan kondisi kerabang telur. Warna kerabang yang berbeda dipengaruhi oleh jenis pigmen,konsentrasi pigmen dan struktur kerabang. Intensitas warna coklat dari kerabang telur dibedakan menjadi 3 kelompok yaitu telur dengan warna coklat tua, coklat dan coklat muda. Telur dengan warna kerabang coklat tua mempunyai kerabang lebih kuat dan tebal dibanding telur yang berwarna coklat muda. Oleh karena itu telur dengan warna kerabang coklat tua mengalami penurunan kualitas lebih rendah dibandingkan warna coklat dan coklat muda. Dalam penelitian ini dilakukan klasifikasi penurunan kualitas telur ayam ras berdasarkan warna kerabang menggunakan support vector machine. Semakin muda warna coklat kerabang telur semakin cepat penurunan kualitasnya. Dengan menggunakan SVM maka dapat diklasifikasikan kualitas telur berdasarkan warna.dengan akurasi 80%. Kata Kunci: Intensitas, Klasifikasi, Kualitas, Warna Kerabang Abstract: Egg quality is a characteristic of eggs that determines the freshness and health of eggs. One element of determining egg quality is based on the condition of the eggshell. Different shell colors are influenced by the type of pigment, pigment concentration and shell structure. The brown color intensity of eggshells is divided into 3 groups, namely eggs with dark brown, brown and light brown. Eggs with dark brown shells have stronger and thicker shells than light brown eggs. Therefore, eggs with dark brown color have a lower quality compared to brown and light brown. In this research, a classification of the quality of chicken eggs based on eggshell was classified using a support vector machine. The younger the eggshell brown color the faster the quality decreases. By using SVM, egg quality can be classified based on color with 80% accuracy Keywords: Classification, Eggshell, Intensity, Quality

Abstract

The persistent challenges in material forming processes arise from recurrent issues encountered during the deep drawing process, particularly involving cracks and deviations from standard thickness dimensions. This article investigates the deep drawing process using both experimental and numerical methodologies. The experimental approach employs a 40-ton capacity power press machine, while the numerical method utilizes the ABAQUS student version software. SPCC-SD (JIS G3141) is the selected material for producing a Dop-pipe 2-inch diameter pipe cap in both approaches. Noteworthy findings include the highest positive and negative correlations observed in elements E 46 and E 48, with values of 0.715 and -0.933, respectively. Minimal disparities, averaging around 4.6% for all components, were evident between the experimental and numerical methodologies. The numerical approach yielded predictive results identifying potential issues in elements E 47 and E 48. This observation did not reveal instances of tearing failure but instead showcased an increase in thickness due to a higher axial force between the dies and punched-in components. The study successfully and accurately predicted product thickness for all components, presenting a contrast with outcomes obtained through the experimental method. Furthermore, this research advances the deep drawing process, extending its applicability to broader material forming applications and ultimately enhancing overall production process efficiency.

Abstract

Pengelasan Austenite Stainless Steel atau baja tahan karat jenis Austenite sering mengalami korosi yang diakibatkan terbentuknya ferrite dengan persentase tinggi sehingga memicu terjadinya korosi. Pada pengelasan stainless steel digunakan backing gas untuk menghambat kontaminasi kotoran dari lingkungan sekitar masuk ke dalam logam las dan menyeimbangkan fase austenite-ferrite sehingga menghambat proses carbide chrome. Di pekerjaan lapangan penggunaan backing gas menggunakan gas Argon dan dilakukan hanya pada daerah akar las, sedangkan proses oksidasi tetap terjadi saat proses pengelasan daerah hot pass hingga capping. Penelitian ini bertujuan untuk menganalisis pengaruh variasi backing gas terhadap nilai kekerasan dan hasil struktur mikro pada baja tahan karat austenitic 316L. Pada penelitian ini dilakukan pengelasan metode GTAW dengan logam induk baja tahan karat austenitik type 316L ketebalan 4mm dengan tipe sambungan V, dengan memvariasikan flowrate pada backing gas Argon pada masing-masing proses pengelasan. Setelah proses pengelasan dilakukan pengujian Non Destructive Test Radiography untuk mengetahui hasil fisik dari pengelasan menggunakan variasi flow rate pada backing gas Argon tersebut, pengujian metalografi dengan mikroskop optik dan uji kekerasan. Hasil pengujian menunjukan bahwa dengan memvariasikan flow rate pada backing gas menggunakan Argon (AR) menghasilkan adanya proses pelapisan nitriding CR pada material hasil las GTAW. Penambahan flow rate pada backing gas menyediakan pereduksi yang dapat melindungi atau menetralkan pertumbuhan oksida yang lebih efekstif pada pengelasan material austenic stailnless steel. Serta dapat memperbaiki hasil uji Hardness Test dan Microstructure terhadap material tersebut. Sehingga dapat dinyatakan dengan memvariasikan flowrate pada backing gas Argon dapat diterapkan pada pengelasan GTAW
