Judul: Verifikasi Flushing pada Sistem Transportasi Curd Yogurt dari Tangki Storage ke Mesin Filler
Abstrak: Flushing is an urging process to help water or material transportation in pipe. Flushing consisted of initial flushing and end flushing. Verification is a method of flushing efficiency. Industry never verified flushing before, so the aims of this internship were to verify flushing from storage tank to filler machine, to know initial flushing reduction in a month production and saving material at end flushing. Parameter used for verification is total solid. Industry used 90 liters from T500 and 95 liters from T501 for initial flushing, and 32 liter for end flushing without distinguished tank. After verification, for initial flushing from T500 needs 88 liters and from T501 needs 84 liters, otherwise for end filling can only save 28 liters. Therefore, material reductions for initial flushing are 2 liters from T500 and 11 liters from T501, but at end flushing can not save more material because of product quality. Assumed that stirred yogurt production 5 times in a month, then the amount of material reduction for flushing at least 10 liters/month.

Judul: Kajian Peluang Aplikasi Produksi Bersih Di Industri Yoghurt (Studi Kasus di PT. Mutiara Mandiri Jaya)
Abstrak: Yoghurt beku yang diproduksi oleh PT. Mutiara Mandiri Jaya masih menimbulkan permasalahan yang dapat berdampak pada lingkungan dan mutu produk yang dihasilkan. Penelitian ini bertujuan untuk memberikan rekomendasi produksi bersih terbaik untuk diterapkan. Metode yang digunakan adalah analisis quick scan, identifikasi permasalahan, analisis peluang produksi bersih, dan analisis kelayakan kuantitatif dari aspek teknologi, ekonomi, dan lingkungan. Berdasarkan hasil penelitian teridentifikasi permasalahan pada berbagai aspek, yaitu belum dilakukan pengujian mutu bahan baku, tata letak pabrik yang tidak sesuai dengan aliran proses produksi, parameter suhu dan waktu pada pasteurisasi dan fermentasi yang belum optimum, pemborosan energi pada proses pembekuan, tata laksana pekerja yang masih tidak efektif, adanya produk gagal, dan limbah yang masih terbentuk berupa 1% buih hasil fermentasi, 2,43% ceceran yoghurt, 0,4% sisa padatan yoghurt yang tidak ikut tersaring, dan 18 kg limbah plastik per hari. onsumsi energi pada bagian produksi sebesar 93% dan bagian non produksi sebesar 7%. Produksi bersih yang direkomendasikan dan telah disesuaikan dengan kondisi di industri adalah penerapan Uji Alkohol, penerapan Good Manufacturing Practice (GMP), perbaikan tata letak pabrik, menjalankan proses dalam kondisi optimum, penghematan energi pada proses pembekuan, dan pemberian standar takaran dalam penambalian essense. Berdasarkan hasil analisis kelayakan kuantitatif, keenam alternatif tersebut layak untuk diterapkan, baik dari aspek teknologi, ekonomi, dan lingkungan.

Judul: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
