Judul: Mempelajari Pengaruh Cara Penggorengan dan Penambahan Zat Pengemulsi Pada Pembuatan Peanut Butter
Abstrak: Tujuan dari percobaan ini untuk mempelajari pengaruh cara penggorengan dan penambahan zat pengemulsi (CMC) da- lam pembuatan peanut butter selama waktu penyimpanan ku- rang lebih dua minggu, dalam rangka memperoleh stabilitas emulsi yang baik. Dalam percobaan ini perlakuan yang digunakan terdiri dari tiga faktor yaitu cara penggorengan, penambahan CMC dan lama penyimpanan. Cara penggorengan terdiri dari dua taraf yaitu cara penggorengan tanpa minyak dan dengan mi- nyak, penambahan CHIC terdiri dari tiga taraf yaitu 0.0 per- sen, 1.0 persen dan 2.0 persen, lema penyimpanan terdiri dari tiga taraf yaitu O minggu, 1 minggu dan 2 minggu. Rancangan Percobaan yang digunakan edelah Rancangan Kelom- pok dengan Percobaan Faktorial, dan dua kali ulangan.

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.
