Puskesmas information system based on WebGIS: Case study city of Bandung

Puskesmas (health centers) is one of the spearheads of health services to the community in Indonesia. Through Puskesmas, government could provide health care and run the program for public health at the same time. But people have problems in accessing information about the existence and health services in Puskesmas. Besides that, the government also have difficulties to monitor the level of service to the community in Puskesmas. In the current condition Puskesmas remains untouched by information technology and communication whereas it could be facilitate community and government in Puskesmas optimization function. This research is about developing first stage of prototype application of information systems based on Web-GIS (Web Geographical Information System) for puskesmas called SIGAPNAS. This application could help communities and governments in search for the location of Puskesmas, availability of health personnel and equipment, as well as the condition of Puskesmas. The prototype is also expected to optimize the role of Puskesmas in improving public health quality. At this stage the Puskesmas area that included are Bandung city, West Java.

Performance analysis of social-aware content-based opportunistic routing protocol on MANET based on DTN

Nowadays, almost all telecommunication devices use TCP/IP to communicate with each other. However, it is difficult for MANET to support the type of end-to-end connectivity required by TCP/IP-based communications due to disruptions, frequent topology changes and network partitions caused by the movement of the nodes. DTN is an emerging paradigm in the telecommunication network which is able to provides data communication in areas with intermittent connectivity, long delay communication, and high error rate. SCORP (Social-aware Content-based Opportunistic Routing Protocol) is a routing protocol on DTN which works by taking account of social proximity and content interests on each node before replicating the message to the other node in order to improve the ability of network in sending messages. In this paper, we show the performance analysis and the advantages of SCORP compared with Epidemic and Spray and Wait under different number of buffer size and nodes on the network. We also show the impact of different number and types of interests per group of nodes on the performance of SCORP. We use Braga and Asia-Afrika area in Bandung as the simulation area in The ONE Simulator.

Analysis secure socket layer protocol with heartbleed bug and distributed denial-of-service

Nowadays one-way communications such as video streaming are easier to be used. One of service which eases those communications is Internet Protocol Television. By easiness of service packet-based that has entered in the whole of world made simplifies access of IPTV services. This research simultaneously uses 2 types of attacks. Those are Distributed Denial-of-Service and Heartbleed bug, with hacker or penetration tester does not belong to examiner. In the final task, the experiments of analysis are taken from 3 scenarios: using VLC program, web page-interface, and web page-interface after being attacked by penetration tester or hacker, with Open-Shortest Path First as routing protocol, and Protocol Independent Multicast as grouping of videos IP. The result has showed that Heartbleed bug did not detect on this experiment related to the result of QoS parameters, while DDoS could disturbed the stabilities of network performance.

Performance analysis of dLife routing in a delay tolerant networks

Delay Tolerant Network (DTN) is a wireless network that connected in an intermittently manner and have dynamic topology. In DTN to design protocol routing is a big challenge due to there is no end-to-end path. To overcome this challenge there is protocol routing dLife. dLife is a protocol routing in DTN that use two utility function to determine forwarding decision, namely TECD (Time-Evolving Contact Duration) and TECD importance. In this paper we study the impact of buffer size and message size on the performance of dLife routing. For the simulation we used Opportunistic Network Environment (ONE) Simulator. The performance that is analyzed are Overhead Ratio, Delivery Probability and Average Latency. Based on simulation result, buffer size and message size affect to the performance of dLife routing.

Polygon WebGIS of distric level for development and monitoring of PUSKESMAS in health care services

In the future, Community Health Center (PUSKESMAS) spread throughout Indonesia is expected to play an important role in improving public health. Currently, the government still has obstacles in monitoring the readiness level of PUSKESMAS service and conditions. This research is aimed at creating a prototype, web-based geographic information system (WEBGIS) with the polygon method. This application is used as PUSKESMAS monitoring apps at the district level. Monitoring conditions include the availability of health workers, medical equipment standards, the PUSKESMAS kind and type, PUSKESMAS building conditions, as well as the spread of disease. This application is named SIGAPNAS (Sistem Informasi Geografis PUSKESMAS Nasional); a prototype of this application is an earlier prototype development that is expected to assist the public in seeking PUSKESMAS information. This application can also help the government in monitoring the development and levels of PUSKESMAS and the spread of a disease in an area. SIGAPNAS is expected to help the government succeed in national health programs through information technology.

Performance analysis of Cubic and Yeah TCP implementation using BATMAND over MANET

In recent years, several TCP congestion control algorithms have been proposed to increase the ability of TCP in high-speed and long distance networks. One of TCP implementations, which in MANET, opened new challenges for those algorithms to demonstrate the stability, scalability, and efficiency of the mechanism. This paper compared two TCP congestion control algorithms, namely Cubic TCP and Yeah TCP by using BATMAND in several static and mobile node scenarios. In addition, we also investigated the impact of slow start optional modifications to the performance of both TCP. Based on the gained insight, we assume that Yeah TCP has better performance due to its capability to anticipate loss events on MANET, and slow start optional modification at some values has significant effect to TCP performance.
