 Abstrak Meningkatnya permintaan pembaharuan aplikasi berbasis open source karena seiring meningkatnya jumlah pengguna sistem operasi Linux, oleh karenanya ketika banyak pengguna linux yang melakukan permintaan pembaharuan aplikasi menyebabkan lambatnya kecepatan unduh dan membutuhkan waktu lama. Salah satu solusinya yaitu dengan membuat mirror repository linux agar memudahkan dan menawarkan koneksi pengguna yang lebih baik. Namun demikian, suatu saat ketika semakin bertambah jumlah pengguna mirror tersebut akan mengalami penurunan kualitas download hingga dapat mengalami down, sehingga tidak dapat melayani permintaan pembaharuan pengguna dengan baik. Penelitian ini bertujuan untuk merancang dan membangun Mirror Repository Linux dengan menggunakan Load-balanced Mirror Service System (LMSS) dengan mengintegrasikan beberapa MIrror Server yang dibangun secara generate melalui Manage Large Network (MLN), dengan pembagian beban menggunakan Linux Virtual Server (LVS) pada metode Network Address Translation (NAT). Sehingga beban permintaan dari client dapat ditangani Mirror Server secara bersama – sama. Dengan demikian, rata – rata waktu download dapat berkurang sebanyak 17,2 % daripada menggunakan Single Server.AbstractThe increasing demand for open source-based application updates is due to the increasing number of users of Linux operating systems, therefore when many Linux users who request an application update cause slow download speed and takes a long time. One solution is to create Mirror Repository Linux in order to facilitate and offer better user connections. However, a time when the number of mirror users will decrease the quality of download until it can down, so it can not serve user renewal request well. This research aims to design and build linux mirror repositories by using Load-balanced Mirror Service System (LMSS) by integrating multiple Mirror Server generated via Manage Large Network (MLN), with load sharing using Linux Virtual Server (LVS) Network Address Translation (NAT). LMSS there is a Director Server as a counter / load manager that passes on the server, which will be forwarded to the destination server. So that the request load from the client can be handled Mirror Server together. Thus, the average download time can be reduced by 17.2% rather than using a single server.

IPv4 and IPv6 will coexist for a long time, due to ISPes’ inertia in the transition from IPv4 to IPv6. Domain Name System (DNS) is a very important functional unit in the Internet. This paper describres the hierarchy and operating process of IPv6 DNS, IPv6 DNS resolver, and presents the DNS transition from IPv4 to IPv6 in particular. We suggest two methods to implement DNS service during the transition period: DNS-Application Level Gateway (DNS-ALG) with Network Address Translation-Protocol Translation (NAT-PT), and dual stacks. And we also propose their respective operational principles. This paper is of valuable reference for network engineers to construct DNS in the transition phase.

Abstract. The Deba area is intensely affected by frequent shallow landslides triggered by rainfall. Relationships between rainfall and landslides in northern Spain, particularly for rainfall events driving multiple movements simultaneously, have not been explored in depth so far. This contribution explores the role of rainfall in landslide activity during a quite long time span, (60 years), from a large network of rainfall gauges and a complete inventory of landslides, and utilizing three different strategies of analysis. 1,180 landslides have been inventoried, and 3,241 rainfall episodes automatically recognized and characterized in terms of rainfall amount, duration and intensity. Antecedent rainfall has also been considered. Six episodes of intense rainfall, which have produced multiple landslides (> 50 % of the recent past occurrences) have been identified. The analysis provides different results: the extraordinary character of the triggering rainfall has been assessed, the meteorological conditions associated to those extreme episodes have been recognized and empirical rainfall threshold producing multiple landslides has been found (I = 7.7D-0.428) and compared with others described in literature. Results show that multiple landslide occurrences are triggered by extreme convective rainfall, intense, short and with limited horizontal extent, as well as a marked summer-autumn seasonality, characteristic of Mediterranean climate.

Sejalan dengan perkembangan teknologi informasi, peralatan-peralatan pendukung jaringan komputer masih sangat diperlukan. Peralatan tersebut pun kini menjadi komponen penting dalam pembangunan jaringan komputer. Router adalah salah satu komponen pada jaringan komputer yang mampu melewatkan data melalui sebuah jaringan atau Internet menuju sasarannya, melalui sebuah proses yang dikenal sebagal routing. Router berfungsi sebagal penghubung antar dua atau lebih jaringan untuk meneruskan data dan satu jaringan kejaringan lainnya. Router sendiri berharga tinggi dan masih sulit dijangkau oleh kalangan masyarakat kita. Router Mikrotik adalah solusi murah bagi mereka yang membutuhkan sebuah router handal dengan hanya bermodalkan standalone computer dengan sistem operasi Mikrotik. OIeh sebab itu, penulis merasa perlu membahas tentang " Kajian Network Address Translation Penghubung Ip Public Dan Ip Private". Dalam pembahasan penulis menitik beratkan pada membuat sebuah Topologi Local Network dengan IP Private untuk terhubung dengan IP Public”.Kata kunci: Jaringan Komputer, Topologi, Router, NAT

The Village

A problem that existed in the government of Pecalongan village, Bondowoso regency, namely service to Pecalongan village people who still adhered to conventional system. This makes the service in the village office less than the maximum, and also requires a relatively long time in terms of doing the service. In addition, in terms of data storage is still using paper that prone to damaged and lost. And also in terms of data search that can take a relatively long time. It is considered less effective and efficient if run in the modern era as it is today. The objective of the research is to design and build a Service Information System at village level to improve service quality for village officials and use of services for villagers. The benefit derived from this research is that this system can facilitate village officials in collecting data of villagers and facilitate the service of residents or citizens in the application of letters. This village service information system is based on website that can be used online, so the Village community can enjoy the Village service more quickly and easily because the service system can access from anywhere. It is expected that with this village information service system, it can improve the quality of service process to the community in Pecalongan village, Sukosari sub-district, Bondowoso regency.

Everyone involved in geospatial information systems has heard of Environmental Systems Research Institute (Esri)company. Most people have tried ArcGIS software at least for one time. Esri has been the pioneer in this industry for a long time; it also defines the future of geospatial trends. In this chapter, the author adopts a neutral position to discuss the relation of Esri and open-source community. They cover almost every aspect where Esri and open source co-occur. Even the latest achievement of Esri, which is R-bridge, is discussed here. Going into the details of everything is not the goal of the chapter; however, a minimum description is provided for each section. Proper references are given to the reader for further study.
