Asam humat merupakan senyawa akhir hasil dekomposisi dan humifikasi sehingga lebih bersifat resisten. Peranan asam humat antara lain : bahan penguat untuk meningkatkan efisiensi remediasi elektrokinetik dari kontaminasi arsenik , membatasi toksisitas Cd dan Pb pada cacing tanah di dalam tanah, agen penyemen dalam matriks tanah untuk menekan degradasi lingkungan tambang mineral. Penelitian dilakukan guna mendapatkan ektrak asam humat dari kompos limbah pertanian dan peternakan. Asam humat diekstrak dari kompos dengan menggunakan asam kuat dan basa kuat. Kompos dari Kotoran ayam diharapkan menjadi solusi  limbah peternakan yang berpotensi mencemari lingkungan. Pembuatan kompos kotoran ayam dipadukan dengan limbah dan gulma pertanian seperti jerami, bonggol jagung, bonggol pisang, kulit durian dan eceng gondok. Dekomposisi dilakukan dengan bantuan biodekomposer EM4, Ragi Kompos dan Cacing tanah. Gugus fungsional yang menjadi penciri asam humat dari kompos kotoran ayam dengan beragam bahan tambahan dan biodekomposer yakni Puncak serapan 3450 - 3300 cm-1 , 2980-2920 cm-1,  1660-1630 cm-1 dan 1170-950 cm-1 . derajat humifikasi yang rendah di semua perlakuan merupakan penciri kompos dengan dengan tong berjalan efektif. EM4 paling efektif untuk meningkatakan laju dekomposisi bahan organikpada perlakuan

The IRμs™ is the first fully integrated system for Fourier transform infrared (FT-IR) microscopy. FT-IR microscopy combines light microscopy for morphological examination with infrared spectroscopy for chemical identification of microscopic samples or domains. Because the IRμs system is a new tool for molecular microanalysis, its optical, mechanical and system design are described to illustrate the state of development of molecular microanalysis. Applications of infrared microspectroscopy are reviewed by Messerschmidt and Harthcock.Infrared spectral analysis of microscopic samples is not a new idea, it dates back to 1949, with the first commercial instrument being offered by Perkin-Elmer Co. Inc. in 1953. These early efforts showed promise but failed the test of practically. It was not until the advances in computer science were applied did infrared microspectroscopy emerge as a useful technique. Microscopes designed as accessories for Fourier transform infrared spectrometers have been commercially available since 1983. These accessory microscopes provide the best means for analytical spectroscopists to analyze microscopic samples, while not interfering with the FT-IR spectrometer’s normal functions.

Automatic Transmission (AT) system is efficient in the aspects of vehicle safety, comfort, reliability and driving performance. The objectives of this paper are to collect the oil samples from AT systems of engine bus according to manufacturer's recommendations and analyse collected oil samples using oil analysis technique. The sample transmission fluid which was taken from the AT gearbox has been experimentally analyzed. The oil samples were taken with an interval of 5,000km, 30,000km, 50,000km, 80,000km, 180,000km and 300,000km for AT bus operation. These samples then have been analyzed by comparing between new and used transmission fluid using Fourier Transform Infrared (FTIR) spectroscopy. Oil analysis by FTIR is a form of Predictive Maintenance (PdM) to avoid major failure in machine elements. Most machine elements are not easily accessible in the transmission system. Having a reliable technique would avoid the needs to open the components unnecessarily, hence, help to prevent catastrophic failure which are very costly, and ease of regular monitoring. In order to identify the major failures of automatic gearbox, forecasts can be made regarding the lube transmission fluid analysis test. By using this test, the minor problems can be determined before they become major failures. At the end of this research, the wear particles profile for interval mileage of AT system was obtained.
