Many institutions, including high schools, own a large number of analog or ordinary microscopes. These microscopes are used to observe small objects. Unfortunately, object observations on the ordinary microscope require precision and visual acuity of the user. This paper discusses the development of a high-resolution digital microscope from an analog microscope, including the image processing utility, which allows the digital microscope users to capture, store and process the digital images of the object being observed. The proposed microscope is constructed from hardware components that can be easily found in Indonesia. The image processing software is capable of performing brightness adjustment, contrast enhancement, histogram equalization, scaling and cropping. The proposed digital microscope has a maximum magnification of 1600x, and image resolution can be varied from 320x240 pixels up to 2592x1944 pixels. The microscope was tested with various objects with a variety of magnification, and image processing was carried out on the image of the object. The results showed that the digital microscope and its image processing system were capable of enhancing the observed object and other operations in accordance with the user need. The digital microscope has eliminated the need for direct observation by human eye as with the traditional microscope. [ABSTRACT FROM AUTHOR]

Banyak institusi, termasuk sekolah-sekolah, memiliki sejumlah mikroskop analog atau mikroskop biasa. Mikroskop ini digunakan untuk mengamati obyek-obyek kecil. Sayangnya, pengamatan obyek menggunakan mikroskop biasa memerlukan ketelitian dan ketajaman penglihatan yang tinggi dari penggunanya. Makalah ini membahas pengembangan mikroskop digital resolusi tinggi dari mikroskop analog, termasuk perangkat lunak pemroses citra digitalnya. Perangkat lunak yang dikembangkan memungkinkan pemakai mokroskop digital merekam, menyimpan dan memproses citra digital dari obyek yang sedang diamati. Mikroskop digital ini dibuat dengan material yang mudah didapat di Indonesia. Perangkat lunak pengolah citra digital yang dikembangkan mampu menangkap citra, menyimpan citra, mengubah kecerahan citra, memperbaiki kontras citra, mengekualisasi- histogramkan citra, merubah skala (scaling) citra dan memotong (cropping) citra. Mikroskop digital yang diusulkan mempunyai kemampuan memperbesar obyek sampai dengan 1600x dengan resolusi citra yang dapat divariasi dari 320x240 sampai 2592x1944 piksel. Mikroskop yang dibuat diuji dengan dengan berbagai preparat obyek dengan berbagai pembesaran, dan pemrosesan citra digital dilakukan pada citra obyek tersebut. Hasil pengujian menunjukkan bahwa mikroskop digital dengan sistem pengolah citranya mampu dipakai untuk mengamati preparat dan melakukan operasi citra preparat sesuai dengan keperluan pengguna. Mikroskop digital ini telah dapat menggantikan pengamatan langsung secara manual yang memerlukan ketajaman mata yang tinggi yang dilakukan pada mikroskop biasa. [ABSTRACT FROM AUTHOR]
