KATALOGISASI KOLEKSI PERPUSTAKAAN KECIL DAERAH SINDANGLAYA

Library services are an illustration of the fulfillment of library functions. One of the services that must be provided in the library is a catalog service. A service that makes it easier for users to find the collection they need in addition to asking a reference service. The catalog has three objects as mentioned by Cutter, namely the find function, the collect function, and the select function. In addition, the existence of a catalog can facilitate librarians in the collection development process. Therefore, a catalog should be in every library. The purpose of writing is to find out whether the use of catalogs in the intended library has been effective? Has the library implemented a catalog service? Is the SLiMS application in the Library effective to use? The author uses qualitative research methods so that the results obtained can be in accordance with the facts that appear and are seen when researchers observe the state of the object, namely the Sindanglaya Small Library. With the results of the study that the Sindanglaya Regional Small Library has not applied catalog services properly, only relying on the arrangement on the bookshelves so that researchers work with managers to use online catalogs by inputting data collections from the library using the SLiMS application. , ,

Multicast Routing Algorithm with QoS Constraints in Mobile Ad Hoc Networks

Through the study of MANET's QoS multicast routing problem, we propose a heuristic-demand multicast routing algorithm. Algorithm combines the MANET network bandwidth estimation algorithm, redefined the select function, restrictions request packets of flooding algorithm, to ensure fair treatment delay and bandwidth. Simulation results show that the algorithm has the advantage of fewer routing overhead, high success rate.

The Development Research of Solar Energy Power Supply Devices

According to the current energy trends, the paper designs a power supply device to keep the Power Supply Platform that the solar power as the main energy, meanwhile the Storage Battery and alternating current as the minor energy working normally. The device has the function of switching the power supply to achieve the uninterrupted power supply to loading in any environment so that will output DC stably and carry three charging to the Storage battery. Through the Ps-pice software simulation results show that the modules can meet the design requirements. It can achieve the results of switching power and select function of the Storage battery power charging module through controlling circuit by Proteus simulation software. The power supply device has the advantages of high reliability.
