Judul: Mempelajari Kegiatan Produksi dan Uji Konsistensi Mutu Baby Cereal
Abstrak: Industri mempunyai hubungan yang erat sekali dengan pengawasan mutu, karena hanya produk hasil industri yang bennutu yang dapat memenuhi kebutuban pasar. Tiap industri pengolahan pangan mempunyai citra mutu pangan yang dilekatkan pada produk pangan yang dihasikan. Citra mutu produk pangan itu ditegakkan dengan usaha mengendalikan mutu, yaitu semua usaha dan kegiatan untuk mencapai tingkat dan konsistensi mutu sesuai dengan citra mutu yang telah ditetapkan oleh perusahaan. Untuk industri pangan, penanganan jaminan mutu dilakukan melalui sistem pengendalian mutu.

Judul: Mempelajari Sistem Pengendalian Mutu pada Proses Produksi Saus Emulsi dan Saus Non-Emulsi di PT. Suba Indah
Abstrak: Perkembangan teknologi dan munculnya era industrialisasi telah memberikan dampak positif bagi perkembangan mutu pangan di Indonesia, diantaranya peningkatan persyaratan mutu konsumen. Untuk mempertahankan mutu, PT. Suba Indah sebagai salah satu produsen pangan telah menerapkan cara berproduksi yang baik (Good Manufacturing Practices atau GMP) dan sistem keamanan pangan yang dikenal dengan HACCP (Hazard Analyfical and Critical Control Point). Sistem ini mengupayakan tindakan pencegahan terhadap tejadinya bahaya yang mungkin tejadi pada mata rantai produksi melalui kegiatan pemantauan, bempa pengamatan langsung kegiatan produksi di lapangan dan pengendalian mutu. Tujuan magang adalah untuk menciptakan keterkaitan (link and match) antara dunia usaha dan perguruan tinggi, untuk meningkatkan keterampilan, penguasaan ilmu pengetahuan dan teknologi dan profesionalisme. Tujuan laimya untuk mempelajari sistem pengendalian mutu untuk produk saus emulsi dan saus non-emulsi, serta membandingkan efek oksidasi yang terjadi pada saus non-emulsi (saus tomat dan saus cabe) produk Hunt's dengan produk pesaingnya.

Judul: Identifikasi Molekuler Kompleks Spesies Himantura uarnak (Batoidea: Dasyatidae) di Indonesia.
Abstrak: Stingrays are one of the cartilaginous fish, apart of sharks and skates, and one of Indonesia's fishery resources. Almost of elasmobranch fishes are economically important fish. The refined products and live specimens of this fish are a lot of traded. Himantura uarnak, H. undulata and H. leoparda are stingray species in Himantura and Dasyatidae family, which are the most popular stingrays in Indonesia waters. The stingrays are major target species were used as a consumable product and trading products. Levels of species diversity of cartilaginous fish in Indonesia are very high, and also Indonesia is listed as one of the countries that use elasmobranch resources the highest in the world. Generally, this study aims to identify each species of H. uarnak species complex through molecular approaches. While specifically, this study aims to estimate the evolutionary process of species divergence and to determine the relationship between species. The methods were used in this study included field sampling, sample collection, and specimen identification, collection of genetic samples, analysis of genetic samples and data analysis . Size polymorphism nuclear DNA markers (intron EPIC) were used. Polymorphism alleles translated into genotypes and alleles frequency of five introns loci. The results of Bayesian analysis and Correspondence Analysis (CA) produced informative diagram of the population structure showed 4 different clusters. Cluster 1 and 4 were H. leoparda, Cluster 2 indicated as H. undulata and the Cluster 3 was H. uarnak. Cluster 1 was a variant of Cluster 4, in this time called as H. leoparda var.1. Separation of four clusters according to nuclear DNA need to be proved by mitochondria DNA maker by cytochrome c oxidase subunit I (COI) and cytochrome b (cyt b). Molecular approaches were using mitochondrial DNA gene cytochrome c oxidase subunit I (COI) and cytochrome b produced 4 main groups (Group I, II, III and IV). Both of these molecular approaches showed each individual of groups were in consistent clade and the main group. Hence the H. uarnak species complex in Indonesian waters were divided into 4 main groups, and each was a particular species. The Group I and IV were the two group species that have been released as H. leoparda and Group I was H. leoparda var. 1 identified as cryptic species. Group II was one individual who grouped as H. undulata. Group III was one of other group that identified as H. uarnak and in accordance with the morphological characteristic through spotting pettern. Morphological approach to identified the stingrays of Himantura uarnak species complex clearly less accurate than the molecular approaches. Morphological approach should not be used to identify a species complex in stingrays without helped by other approaches.
