Having a tsunami early warning system during the tsunami disaster is important. The tsunami early warning system that is widely applied in Indonesia using loudspeakers and information board as a medium to convey information directly to the community during the disaster. The information provided is only about the status of the disaster and what needs to be done. People who panic, tend to choose the evacuation route through the main roads without thinking that the path will become very crowded resulting in total congestion. This paper discusses a tsunami evacuation strategy by finding the shortest path of evacuation route using dijkstra algorithm. This system contains information about the shortest evacuation routes that can be taken by the community towards a safe location, either vertically or horizontally. So, people can evacuate vertically or horizontally based on the geographical location of their residence. This system will be implemented in Cilacap districts. Shortest evacuation route is determined using the djikstra algorithm. Disaster-prone locations is the starting vertex and safe locations is finish vertex.

-One of the important aspects in industrial field is a good material handling in logistics. Automated Guided Vehicle (AGV) can be an alternative to making an optimal logistics system. A widely used type of AGV based on its navigation system is line follower robot. This paper explains about applying the line follower robot integrated with LabVIEW to implement ultrasonic sensor as a radar to determine an empty space in logistic storage. The utilization of ultrasonic radar makes the searching process of empty space in the storage faster. Meanwhile, LabVIEW interface is used to help the operator to monitor material handling process. AGV menjadi salah satu pusat perhatian di dunia industri saat dikarenakan beberapa keunggulan yang dimilikinya yaitu konsisten, fleksibilitas, dan otomatisasi dari sistem tersebut. Selain itu, penggunaan AGV dalam dunia industri juga dapat membantu meningkatkan performa bisnis dari segi ekonomi [4] dan peningkatan kapasitas produksi [5]. Meskipun investasi awal cukup besar, tetapi perusahaan dapat melakukan penghematan dari segi tenaga kerja, sehingga untuk jangka panjang lebih menguntungkan. AGV dapat digunakan pada berbagai area kerja, seperti bagian perakitan, penanganan material pada sistem produksi, penanganan material di gudang/logistik, serta penanganan barang di tempat penyimpanan [6].AGV dapat dibedakan beberapa jenis disesuaikan dengan sistem navigasinya, yaitu berdasarkan jenis lintasannya, kapasitas beban, dan mekanisme pengalamatan pada AGV tersebut [3]. Salah satu jenis AGV yang banyak digunakan dalam industri adalah AGV dengan menggunakan sistem navigasi guide path [3] atau pengikut garis [2]. Pada artikel ini dipaparkan sebuah sistem penanganan material di tempat penyimpanan dengan menggunakan robot pengikut garis yang diintegrasikan dengan antarmuka LabVIEW dan sensor ultrasonik. Algoritma kontrol yang digunakan pada robot pengikut garis agar dapat berjalan sesuai dengan yang diinginkan adalah sistem kontrol PID. Beberapa tahun terakhir ini, pengikut garis dengan menggunakan algoritma lain seperti logika fuzzy juga sudah dikembangkan [7]. *) Penulis korespondensi (Artdhita Fajar Pratiwi)

Dissemination methods of tsunami Information in Cilacap uses voice and siren. There are some constraints on the methods, especially in social aspects for particular society. Utilization of electronic information board is one of alternative solutions that can be offered to the society in responding tsunami information or warning. In this paper, a wireless electronic information board is designed to display the tsunami disaster warning visually. In normal condition or when there is no disaster, the information board can be utilized to display the information about evacuation procedure. The proposed electronic information board is implemented in multicolor using three sets of LED dot matrix panel P10 which have 32 x 16 pixels resolution and is controlled using microcontroller. The result showed that this device was capable to show the tsunami information such as “Status Awas”, “Status Siaga”, “Status Waspada”, and “Evacuation Route”.
