Judul: Aktivitas Ekstrak Daun Miana (Coleus scuttellarioides [L] Benth) Sebagai Antifungi Candida tropicalis
Abstrak: Candidiasis is an infection caused by yeast of Candida tropicalis. One of the leaves thought to contain anti microbial is (Coleus scutellarioides [L] Benth) leaves. The aim of this study is to test the activity of the leaf extract (Coleus scutellarioides [L] Benth) as an antifungal Candida tropicalis in vitro. This using diffusion wells and growth methods. Extracts tested are aquades extract, 70% ethanol extract and acetone extract of leaves miana. The extract can inhibit the growth of Candida tropicalis is miana leaf acetone extract. Minimum Inhibitory Concentration acetone extract solvent is DMSO and acetone, respectively at 25 mg/mL with inhibition zone diameter 1.55 mm and 1.50 mm.The results of statistical tests with SPSS 16.0 software showed that acetone extract of the (Coleus scutellarioides [L] Benth) leaves can significantly inhibit the growth of Candida tropicalis (ANOVA α 0.05) although its inhibition zone diameter is less than Nystatin. Acetone extract was analyzed by GC-MS and have the dominant content of the compound is 2-hexadecen-1-ol, 3, 7, 11, 15-tetramethyl-, [R-[R*, R*- (E)]] – (CAS) phytol and neophytadiene.

Judul: Isolasi dan Karakterisasi Senyawa Antibakteri Ekstra Daun Miana (Coleus scuatellariodes [L] Benth)
Abstrak: Miana is Lamianceae. It is commonly used as traditional medicine for infection and inflamation, cause by bacterial. The aim of this study to isolate and characterize ofantibacterial compound from miana leave extract. It is expected that the result will give information on characteristics and minimum inhibition concentration (MIC) of miana leave extract which have the highest antibacterial activity. The method of this research were extraction by Harborne method, antibacterial activity test by agar well diffution to staphylococcus aureus, staphylococcus epidermidis, Escherichia coli and Salmonella entereditidis and determination of MIC by dilution methode. The result showed that miana extract has the highest antibacterial activity on S. aureus and S. epidermidis. Miana extract was better than fresh and "infusan" miana leave on inhibition activity of S. aureus and S. epidermidis. MIC value of S. aureus and S. epidermidis were 3 mg/ml. The active fraction of maina leave extract contain phthalic acid derivates by GG-MS.

Judul: Penerapan Metode Pemodelan GSTARIMA untuk Peramalan Data Deret Waktu Penjualan Pulsa Provider X di Wilayah Jabodetabek.
Abstrak: Seiring dengan pesatnya pertumbuhan bisnis pertelekomunikasian menyebabkan persaingan yang ketat antar perusahaan. Perancangan strategi penjualan yang baik sangat dibutuhkan agar suatu perusahaan dapat bertahan. Salah satu bentuk persaingan yang terjadi adalah penjualan pulsa. Penjualan pulsa diduga memiliki keterkaitan antar waktu dan lokasi penjualan. Generalized space time autoregressive moving average (GSTARIMA) merupakan metode pemodelan data deret waktu yang memiliki keterkaitan antar waktu dan keterkaitan antar wilayah. Pemodelan GSTARIMA diterapkan pada data rata-rata penjualan pulsa harian provider X di wilayah Jabodetabek. Hasil dari penelitian ini model GSTARIMA yang terbentuk adalah generalized space time integrated moving average atau GSTIMA (1,1,1). Model terbaik yang diperoleh merupakan model GSTIMA (1,1,1) dengan penggunaan matriks pembobot kebalikan jarak yang memiliki nilai RMSE sebesar 24039.72 dan nilai MAPE sebesar 11.555%.
