ABSTRACT
Wayfinding merupakan suatu kegiatan oleh manusia dalam memilih jalur untuk mencapai tempat tujuannya. Proses wayfinding akan bergantung kepada bagaimana sebuah lingkungan dapat terbaca dengan jelas bagi penggunanya. Skripsi ini membahas mengenai hubungan antara peran citra dan konfigurasi ruang yang terkait dengan fungsi dan strategi yang digunakan dalam wayfinding. Studi kasus dengan beberapa responden di sebuah pusat perbelanjaan dilakukan untuk memahami lebih lanjut mengenai hubungan peran citra dan konfigurasi dalam wayfinding. Dari hasil studi kasus dapat disimpulkan bahwa elemen citra memiliki peran yang berguna sebagai penanda ataupun petunjuk untuk mengidentifikasi lokasi keberadaannya. Konfigurasi berperan untuk memfasilitasi elemen citra tersebut untuk dapat diakses secara visual bagi penggunanya yang dapat dimanfaatkan untuk memerkirakan jarak dan arah.
ABSTRACT
Wayfinding is a process on how people choose a route to reach their destination. The success of wayfinding process depends on how the environment can be readable by its users. This thesis describes about the connection between the role of image and configuration of space related to the function of wayfinding and its strategies. A case study was conducted at a shopping mall to get a better understanding about the role of image and configuration in wayfinding. From the case study it can be concluded that image plays an important role at hinting the users to identify the location.

Perusahaan yang memiliki unit ? unit usaha di lokasi tertentu tentunya ingin agar unit - unit usaha tersebut tersambung satu sama lain dalam satu jaringan dan dapat berbagi informasi penting untuk menunjang kelangsungan bisnis perushaan tersebut. Namun aspek privasi dari tiap unit ? unit usaha tersebut tentunya tidak boleh dikesampingkan sehingga aktifiitas penggunaan jaringan oleh suau unit usaha tidak mengganggun unit usaha lain. Salah satu solusi yang bisa digunakan adalah penggunaan VPN. Dimana sumber daya jaringan dapat dipakai bersama namun aspek privasi antar unit usaha tidak dikesampingkan. Salah satu alternatif pengimplementasian VPN adalah dengan L3VPN. Sesuai dengan namanya, backbone untuk menunjang L3VPN ini adalah divais yang beroperasi pada layer-3 yaitu router. Sehingga untuk mempesiapkan jaringan yang dapat digunakan untuk mengimplementasikan L3VPN perlu disiapkan sebuah jaringan backbone yang tersusun dari router ? router yang walaupun tidak tersambung fisik tetapi harus tersambung secara logika. Ketersambungan secara logika ini dapat diakomodasi oleh routing protocol. Dengan studi kasus dimana PT. Indonesia Comnets Plus bermaksud untuk membuat jaringan antar unit usaha PLN di Kota Palembang. Maka akan dilakukan perancangan jaringan yang dapat mendukung pengimplementasian L3VPN dengan memakai routing protocol OSPF yang akan dikonfigurasi menggunakan IOS command pada router.
Enterprise that has several branch unit within area surely wants so that its branch units can connect to each other within one network and share important information in order to support its business operations. Under that constraint, privacy among each branch units may not be neglected so the activity of network using won?t bother other unit branch?s activity. One solutin can be used is to implement VPN, on which network resources can be shared among unit branch and privacy aspect is still considerated. One of the alternative for implementing VPN is to implement L3VPN. Backbone network used for supporting L3VPN is using layer-3 devices, which is router. So, in order to prepare a ntework to ready for L3VPN implementation it needs a backbone network which consist of routers, which are although not physically connected but logically connected. This logical connection between routers can be achieved using routing protocol. With a case study on which PT. Indonesia Comnets Plus want to build network among PLN unit branch at Palembang, a network planning will be carried, under constraint that the network to be designed has to be able to support L3VPN implementation using OSPF dan EIGRP routing protocol configures using IOS command.

Abstrak :

Pengering berbasis Electrohydrodynamic (EHD) adalah suatu sistem pengering yang tidak mengandalkan panas untuk mengurangi kandungan air pada suatu subjek. Pengering berbasis EHD mengandalkan ionic wind, yaitu fenomena bergeraknya gas yang terionisasi oleh suatu elektroda bertegangan tinggi menuju elektroda lain. Berdasarkan berbagai eksperimen, subjek yang diletakkan diantara kedua elektroda tersebut dan terkena ionic wind tersebut akan mengalami peningkatan laju pengeringan. Dikarenakan fenomena ini dapat terjadi pada suhu ruangan, pengeringan EHD dapat diaplikasikan untuk berbagai subjek yang sensitif terhadap suhu tinggi. EHD drying telah banyak di uji dan pengaruh berbagai macam konfigurasinya telah banyak diuji coba. Walau demikian, belum banyak penelitian-penelitian tersebut yang mengarah ke pembuatan rancang bangun dengan kapasitas lebih besar dari skala uji coba dalam laboratiorium. Penelitian ini berusaha memahami faktor-faktor apa saja yang mempengaruhi laju pengeringan dengan alat pengering berbasis electrohydrodynamic serta mengaplikasikannya pada rancang bangun alat pengering berbasis electrohydrodynamic dengan skala lebih besar.


An Electrohydrodynamic Dryer is a dryer system that works without utilizing heat. An Electrohydrodynamic Dryer works by utilizing ionic wind, a phenomenon that occurs when gas, ionized by an electrode of high voltage, moves to another (grounded) electrode. Based on experiments, subject placed between the two electrodes and exposed to ionic wind experiences an increase in drying rate. Since this phenomenon can happen in room temperature, an EHD dryer can be used as a solution to dry heat sensitive subjects. EHD drying has been quite extensively researched and the influence of the various configurations of an EHD dryer has also been recognized. But even then, not much of the research in EHD drying tries to use their findings to build an EHD Dryer with largerthan-lab capacity. This research will try to comprehend the influence of the various configurations of an EHD dryer and apply those findings to create a design of an electrohydrodynamic dryer with a larger scale in mind.
