Pengelolaan dan pengontrolan produk sangat dibutuhkan oleh perusahaan yang bergerak di bidang distribusi farmasi, karena perusahaan distribusi farmasi membutuhkan perencanaan dan pengendalian persediaan dalam hal ini produk farmasi terkait dengan tanggal expired dan batch. Pada tahap analisis kebutuhan sistem terdapat beberapa prosedur yang terkait dengan inventory perusahaan distributor produk farmasi diantaranya adalah pengelolaan qoutation, sales order purchase order, penerimaan barang, retur barang, surat jalan, invoice, pembayaran, barang rusak dan pemusnahan barang. Sistem inventory untuk perusahaan distributor produk farmasi telah berhasil dibangun menggunakan metode Agile Unified Process dengan empat tahapan yaitu inception, elaboration, construction, dan transition. Pada tahapan transition dilakukan pengujian sistem inventory dengan menggunakan metode black box testing. Pengujian menggunakan black box testing ini bertujuan untuk mengetahui error yang terjadi ketika sistem digunakan oleh end user dengan pengujian data normal dan data tidak normal

Thermomechanical pulping (TMP) whitewater was treated in thermophilic (55°C) anaerobic laboratory-scale reactors using three different reactor configurations. In all reactors up to 70% COD removals were achieved. The anaerobic hybrid reactor, composed of an upflow anaerobic sludge blanket (UASB) and a filter, gave degradation rates up to 10 kg COD/m3d at loading rates of 15 kg COD/m3d and hydraulic retention time (HRT) of 3.1 hours. The anaerobic multi-stage reactor, consisting of three compartments, each packed with granular sludge and carrier elements, gave degradation rates up to 9 kg COD/m3d at loading rates of 15-16 kg COD/m3d, and HRT down to 2.6 hours. Clogging and short circuiting eventually became a problem in the multi-stage reactor, probably caused by too high packing of the carriers. The anaerobic moving bed biofilm reactor performed similar to the other reactors at loading rates below 1.4 kg COD/m3d, which was the highest loading rate applied. The use of carriers in the anaerobic reactors allowed short HRT with good treatment efficiencies for TMP whitewater.
