Judul: Menentukan persediaan BBM yang tepat melalui metode EOQ probabilistic (Studi kasus SPBU XYZ di Kabupaten Bogor)
Abstrak: Frequency of fuel ordering at XYZ gas station was irregular because it was decided based on estimated needs. It caused sometimes the tank could be empty or over stock. This condition results in difficulty to predict the provision of funds for fuel payment. According to this problem, it was necessary to analyse the influence of stock volume and total of fuel sale on fuel ordering at XYZ gas station. The objectives of this study were : a) to identify profile and controlling process of fuel inventory at XYZ gas station, b) to analyse cost parameter which influenced fuel ordering, c) to determine optimum of fuel ordering; and d) to determine the right time for fuel ordering. Primary datas were collected by using questionnaires and secondary data were consist of total receipts, sales and stocks of premium, pertamax and diesel (solar) fuel in 2008, and its prices in 2008. Analysis was done by EOQ probabilistic methods.

Saat ini cabang tersebut mengalami kendala dalam mengelola persediaan karena permintaan yang fluktuatif tiap bulannya. Fokus pada penelitian ini adalah mengelola persediaan dari Choco Lava Milo dan Mango Yakult karena permintaannya yang cukup tinggi. Tahap awal dilakukan peramalan sebagai dasar untuk mengendalikan persediaan. Perhitungan persediaan dilakukan dengan Economic Order Quantity (EOQ). Metode peramalan yang dipilih adalah trend analysis karena tingkat kesalahannya terkecil. Berdasarkan hasil EOQ, kuantitas pemesanan optimum untuk Choco Lava Milo sebanyak 241 cup dan Mango Yakult sebanyak 244 cup. Total biaya persediaan yang dikeluarkan dengan EOQ adalah Rp3.367.898 sehingga gerai dapat menghemat biaya sebesar Rp 399.664 per tahun., The growth of the tea and boba market in Indonesia is experiencing rapid growth. One of the tea and boba brands is PT XYZ which has a branch in Dramaga. Currently, the branch is experiencing problems in managing inventory due to fluctuating demand every month.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
