This paper contemplates the Library Management System (MIS) as utility for processing, accessing and retrieving information to support scholarship and decision-making process. It contents that without an organised approach to the Management of Information, in the context of information exploitation scenario, organisations would suffer from information accessibility and retrieval while the clientele may actually findit equally hard to access and make decisions based on the right packaged information. The library MIS is thus considered a utility in the management of knowledge for access and exploitation. It is therefore argued that the library MIS would provide the means and method to manage multimedia-computer based Information Systems to help gain useful, complete and timely information through its objective of satisfying scholarly, academic and administrative information needs of the University. Given that Moi University is multicampus based, boosting of scholarly, academic and administrative clientele that is objective, analytical and information oriented, with the need for the library operational efficiency and organisational effectiveness, it thus calls for the library MIS integrated Multimedia approach to revolutionise its information provision sector. Since the perception of the library MIS objective is measured through its utility for the creation, process, storage, and retrieval of information and given that such MIS supports the library information management process by efficiently processing knowledge and effectively supplying useful information, it directs this paper to postulate the library MIS strategy as well placed and advantageous for accessing, retrieving and sharing information in technologically oriented University environment.

— One important part of the RUM (Roket Uji Muatan / Rocket Payload Test) is the payload. In this paper, payload designed to detect changes in temperature, pressure, and humidity at any altitude changes. To be able communicate with ground segment, used in communications equipment. On occasion it is also designed telecommand function to detect if there is damage to the payload. For payload to function properly, they invented algorithms. From the experiments, the payload can work well for sending data to a ground segment or telecommand to a height of 1 km.

The objective of this research is to develop seismic hazard area zones in the building infrastructure of the Banda Aceh City Indonesia using peak ground acceleration (PGA) measured using global and local attenuation function. PGA is calculated using attenuation function that describes the correlation between the local ground movement intensity the earthquake magnitude and the distance from the earthquake's epicentre. The data used comes from the earthquake damage catalogue available from the Indonesia meteorology, climatology and geophysics agency (BMKG) with range from year 1973 -2011. The research methodology consists of six steps, which is developing the grid, calculation of the distance from the epicentre to the centroid of the grid, calculation of PGA values, developing the computer application, plotting the PGA values to the centroid grid, and developing the earthquake hazard zones using kriging algorithm. The conclusion of this research is that the global attenuation function that was developed by can be applied to calculate the PGA values in the city of Banda Aceh. Banda Aceh city in micro scale can be divided into three hazard zones which is low hazard zone with PGA value of 0.8767 gals up to 0.8780 gals, medium hazard zone with PGA values of 0.8781 up to 0.8793 gals and high hazard zone with PGA values of 0.8794 up to 0.8806 gals.

ABSTRAK: Penelitian yang dilakukan bertujuan mengembangkan sistem informasi geografis (SIG) yang dapat digunakan untuk mengelola data dan menyajikan informasi kegempaan. Metodologi penelitian terdiri dari pengumpulan data spasial dan data non spasial dan perancangan sistem. Perancangan sistem terdiri dari perancangan aliran data, perancangan basisdata, perancangan menu dan perancangan layar. Kesimpulan yang dapat diambil dari penelitian ini adalah bahwa SIG yang dikembangkan dapat menampilkan informasi mengenai bagaimana gempa yang pernah dan sedang terjadi dengan parameter magnitudenya dalam bentuk visual sesuai kondisi yang ada. SIG ini dirancang menggunakan basisdata sendiri dan memiliki kapasitas untuk melakukan pengolahan data spasial dan non-spasial untuk menghasilkan sebuah sistem peringatan dini tsunami. Sistem ini juga dapat mempermudah dan mempercepat penyampaian informasi kegempaan kepada masyarakat.

Research conducted with the aim to develop spatial data cluster and analyse the characteristics of each cluster of data in order to develop spatial zonation of building damage hazard caused by the earthquake in the city of Banda Aceh. The data used consists of the data peak ground acceleration (PGA), lithology and topographic zone data with the four phases of the study consisted of data normalization with min-max method, determination of optimum data group with the connectivity index, Dunn index and the Silhouette index, clustering of data with the k-Means algorithm and the data interpolation using kriging algorithm to construct the zonation of hazard area. The optimum numbers of clusters used in these researches are two, with the first 170 data largely concentrated at a distance of less than 0.1 to 0.5 from the cluster centre and the second 55 others data concentrated at a distance of 0.3 -0.5 from the cluster centre. Banda Aceh and surrounding areas can be spatially divided into two classes of potential building damage caused by the earthquake with high hazard class building damage are generally located near the coastline.

The research that has been done aims to develop local hazard zoning due to earthquake damage to buildings using Kohonen NN and kriging algorithm. The data used in this research consists of data of earthquake, lithology, and topography zone. Data of earthquake is obtained from the catalog of damaging earthquake period 39 years of national meteorology, climatology, and geophysical (BMKG) office which the source of the earthquake was 5 Km radius from the center of Banda Aceh City, Indonesia. The research method consists of a set of estimation staging of PGA from the data of earthquake, converted data of lithology and topography zone, clustering data with Kohonen NN and zoning hazard area using kriging algorithm. Kohonen NN and kriging can each be implemented adequately to categorize the data with the success percentage up to 99.2 percent and for zoning of the building damage hazard area which constitute hazard zone of low, medium, and high. Zonation of earthquake building damage hazard...

The objective of this study is to create building damage hazard zonation area using fuzzy kohonen clustering network (FKCN) for physical parameter data clustering and inverse distance weighting (IDW) for data interpolation in Banda Aceh city, Indonesia. IDW algorithm is used alongside FKCN because of its simplicity. The physical parameter in this study consists of lithology, topographic zone and peak ground acceleration value (PGA). The result is Banda Aceh city divided into 3 zones which are low, medium, and high building damage area, based on the combination of physical parameter on each area

Spatial autocorellation is very rarely implemented for analyzing erathquakes and disasters. The purpose of this research is to compare individual spatial patterns for building damage hazard data due to earthquake in the form of lithology data, topography zone and peak ground acceleration data (PGA). The research methodology consists of a series of data converstion from ordinal to interval data, creation of spatial weighting matrix of rook and queen, the determination of spatial autocorrelation using local indicator of spatial association (LISA) and hostspot analysis usingGetis-OrdGi* statistics and the mapping of spatial patterns.The research concluded that the individual spatial pattern as a result of categorizing data with high significance from the analyzed variable using LISA test and hotspot analysis is determined by variable types and weighted spatial matrix.The test using spatial weighting matrix rook shows that the three variables which is being analyzed, is much better spat...
