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: Aktivitas Antifungi Ekstrak Daun Miana (Coleus scutellariodes [L] benth) pada Pertumbuhan Candida albicans Secara In Vitro
Abstrak: Miana (Coleus scuttellariodes [L] Benth) is one of the traditional medicine from family Lamiceae having flavonoids, tannins, saponins, steroids, and triterpenoids compound those can be used as antifungal. The objectives of this research were to examine the antifungal activity of Coleus scuttellariodes [L] Benth leaves extract against C. albicans and to analyze the active compounds in Coleus scuttellariodes [L] Benth leaves extract that has potential as an antifungal against C. albicans. The methods of this research were extraction with aquades, etanol 70%, and acetone, antifungal activity test by agar well diffusion and identification of active compound extract with the best inhibition in antifungal activity with Gas Chromatography-Mass Spectrometry (GC-MS). The result showed that acetone extract 400 mg/mL had the highest inhibition activity with the zone of 4.66 mm included in the low category, meanwhile aquades and etanol 70% extract did not show antifungal activity. Positive control nystatin concentration of 1.028 mg/mL is more effective in inhibiting of C. albicans. Minimum inhibition concentration value of acetone extract was 1.56 mg/mL. Identification of acetone extract with GC-MS result phytol in amount of 41.29%.

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%.
