Union Catalog Dalam Sistem Jaringan Perpustakaan

A bstrak: Ada kalanya dalam satu kola terdapat beberapa perpustakaan. Begitu juga dalam satu lingkungcrn universitas yang terdiri dari beherapa falcuftas dengan masingmasing perpustakaan. Untuk mengefisiensikan penggunaan kalalog untuk pengguna, maka diperlukan adanya kebijakan pembuatan katalog inchrlaunion catalog balk secara manual ataupun katalog induk online. Untuk keperluan tersebut diperlukan standarisasi format data bibliografi, agar data dari masing-masing perpustakaan bisa dipertukarkcm awn digabungkan. Standar format data yang digunakan antara lain adalah INDOMARC (Indonesia Machine Readable Catalog) Key word: Katalog Induk - Jaringan Perpustakaan - Sistem Informasi Perpustakaa

Pengaruh Pengaturan Jarak Elektroda Busi Pada Unjuk Kerja Motor Bensin (Effect of te Sparkplug electrode Gap on Gas Engine Performance)

Unjuk Kerja motor bakar sangat terganlung pada kesempurnaan pembakaran campuran bahan bakar dengan udara dalam ruang bakar di tiap-tiapsilinder. Untuk motor bensin, kesempurnaan pembakaran tersebut tergantung pada berhasil atau tidaknya loncatan bunga api/ listrik (pada elektroda busi) membakar semua bahan bakar yang masuk ke ruang bakar tiap-tiap silinder. Keberhasilan pembakaran tersebut sangat diperngaruhi oleh keberhasilan timbulnya loncatan bunga api di elektroda busi oleh sistem dan pengaturan waktu loncatan bunga api tersebut. Pada penelitian ini, faktor pengaturan waktu loncatan bunga api disesuaikan dengan data mesin sehingga yang menjadi variabel hanya faktor pertama. Penelitian dilaksanakan dengan menggunakan peralatan standard yang ada pada motor bensin di laboratorium konversi energi. Pengamatan unjuk kerja mesin dilakukan pada beberapa macam pengaturan jarak elektroda busi. Variasi jarak yang digunakan adalah 0,5, 0,6, 0,7, 0,8, 0,9 dan 1 mm. Dari basil pengamatan terlihat bahwa untuk mesin FORD CORTINA (1300 cc), jarak elektroda busi yang optimal berada di sekitar 0,8 dan 0,9 mm. Konsumsi bahan bakar spesifik hampir sama dengan jarak 1 mm tetapi memberikan daya yang lebih besar (setelah pembukaan katub 20 â 30%). Untuk keperluan/kondisi khusus (misal, pembebanan tinggi, konsumsi bahan bakar rendah), maka bisa dipilih jarak elektroda busi yang paling menguntungkan sesuai dengan data hasil pengamatan. Kata Kunci : Elektroda busi, Unjuk Kerja Mesin

Library and Information Science Education in Arunachal Pradesh

This article presents an overview of LIS education in Arunachal Pradesh. Arunachal Pradesh (A.P.) has several private universities offering LIS schooling, but no Government authority organizations currently offer LIS. The author further recognizes a few issues concerning LIS schooling in A.P alongside specific ideas for development. The findings suggest that more effort is required to establish LIS education in AP by the authorities of Arunachal Pradesh, Rajiv Gandhi University, Library Association, and LIS Professionals of Arunachal Pradesh to provide stable and quality education in LIS

Simulasi Antrian Service Mobil Divisi Service (Studi Kasus PT Nusa Sarana Citra Bakti Palembang)

The consumer need is increase for vechicle service in the Service Division of PT Nusa Sarana Citra Bakti as a main dealer for Suzuki cars. There is unserved queue, the kind of service item, amount of mechanic and number of stalls will affect the time of consumers in the system for service vehicles. This final report presents the results of simulation modeling and analyzing systems using queuing system to reduce the time consumers in the system. Queuing model applied in registration was a single channel multi phase, and the stall applied multi channel single phase. The simulation model was built using the modeling software Promodel 7.0. This simulation model use consumer car as an entity, 12 mechanic, and 12 stall as the resources. In the real system, the average time consumer in registration are 3,48 minutes, the average service time for all stall are 75,47 minutes, the average time in system are 78,95 minutes,the average time waiting are 4,00 minutes, the average of car output are 36,33 cars per day, and the average profit are Rp 526.536.653,78 per month. In the model of simulation, the average time consumer in registration are 3,69 minutes, the average service time for all stall are 68,67 minutes, the average time in system are 72,36 minutes, the average time waiting are 3,51 minutes, the average of car output are 35,93 cars per day. The simulation model of proposed system, by adding one stall will produce average time in registrasion are 1,91 minutes, and the average service time for all stall are 70,77 minutes, the average time in system are 72,68 minutes, the average time waiting are 0,44 minutes, the average of car output are 38,84 cars per day, and the company will receive the average profit Rp 596.467.120,20 per month. In the first month, the profit is decrease Rp 39.000.000,00 as the cost of return on investment. In the clustering of proposed simulation will produce the average time consumer in registration are 1,86 minutes, the average time waiting are 0,41 minutes, the average service time for stall express are 51,89 minutes, the average time in system are 53,75 minutes, and average of car output are 37,27 cars per day. The average service time for stall heavy are 202,59 minutes, the average time in system are 204,45 minutes, the average car output are 3,63 cars per day, and the average profit of clustering are Rp 597.299.335,63 per month
