The size of the data that is owned by an application today is very influential on the amount of space in the memory needed one of which is a mobile-based application. One mobile application that is widely used by students and the public at this time is the Complete Natural Knowledge Summary (Rangkuman Pengetahuan Alam Lengkap or RPAL) application. The RPAL application requires a large amount of material storage space in the mobile memory after it has been installed, so it can cause this application to be ineffective (slow). Compression of data can be used as a solution to reduce the size of the data so as to minimize the need for space in memory. The levestein algorithm is a compression technique algorithm that can be used to compress material stored in the RPAL application database, so that the database size is small. This study describes how to compress the RPAL application database records, so as to minimize the space needed on memory. Based on tests conducted on 128 characters of data (200 bits), the compression results obtained of 136 bits (17 characters) with a compression ratio is 68% and redundancy is 32%.Keywords: compression, levestein, aplication, RPAL, text, database, mobile

AbstractAmmonia and sodium hydroxide are two important inorganic bases which served as the basis or precursors of other compounds with multiple uses. Some of their derived salts, i. e. ammonium nitrate, are of the paramount importance for daily life. Others salts, such as lithium carbonate, are gaining a primary role in the development of smart technologies, i. e. E-cars. This chapter described developments in the production of these useful compounds: ammonia, sodium and potassium hydroxides, related salts, i. e. ammonium nitrate, sodium and potassium carbonates, and finally, lithium carbonate.

In Khmer, the word prek designates a connection between things. In Kandal province in Cambodia, preks crisscross the landscape, connecting rivers with floodplains, supporting rich ecologies and a variety of livelihoods. Drawing on science and technology studies (STS) and critical water research, this paper explores prek(s) as a multiplicity. Rather than taking the prek as a passive object around which various practices occur, we examine how prek(s) are enacted as ontologically different: as irrigation infrastructure, as pathway to rice intensification, as device for Cambodian state-making, and as climate-friendly agricultural development. After analyzing interference patterns between enactments and their scale-making effects in- and outside the Mekong floodplains, we make explicit our own ontological politics. Focused on sustaining multiple uses and ecosystems, “our” prek is a socionatural mosaic landscape where many human and more-than-human actors and practices can coexist. This ontological politics, we suggest, has implications for planetary environmental knowledges and delta management far beyond Kandal’s landscape.
