<p><em>Abstrak</em> - <strong>Keamanan rumah menjadi hal yang sangat penting ketika pemilik rumah meninggalkan rumah dalam keadaan kosong. Selain pencurian, kebakaran juga merupakan masalah yang sering kali terjadi ketika rumah ditinggal pemiliknya. Sebagai alternatif solusi untuk menjaga dan mengawasi rumah yang diajukan pada penelitian ini ialah menggunakan teknologi Jaringan Sensor Nirkabel yang terintegrasi dengan jaringan internet, sehingga pemilik rumah tetap dapat mengawasi keadaan rumah dari jarak jauh. Pada penelitian ini dirancang prototype sistem rumah pintar atau Smart Home yang memanfaatkan teknologi Jaringan Sensor Nirkabel menggunakan standard Zigbee. Beberapa node sensor ditempatkan pada peralatan rumah, dimana setiap node dapat saling berkomunikasi secara wireless dan terpusat di node kordinator. Selanjutnya node kordinatior akan terhubung ke jaringan internet sehingga pemilik rumah dapat membuka aplikasi smart home kapan saja dan dimana saja. Rancangan sistem <em>Smart Home</em> disimulasikan menggunakan rumah model untuk menguji kinerja perangkat <em>Smart Home</em>. Pengujian kinerja Smart Home dimulai dengan pengujian keakurasian masing masing data sensor hingga waktu respon komunikasi dari sensor ke pusat monitoring. Tingkat error pembacaan suhu disetiap ruangan ialah 1 - 4.27%. Sensor PIR berhasil mendeteksi keberadaan orang di suatu ruangan dengan waktu delay </strong><strong>adalah 2.8 detik dengan jarak maksimal 5 meter</strong><strong>. Fungsi kendali dan monitoring (<em>on/off</em>) perangkat elektronik bekerja dengan baik, dengan waktu respon kurang dari 1 detik. Dari hasil pengujian komunikasi nirkabel antar node, diperoleh bahwa jarak maksimal antar node ialah sekitar 20 m, dengan rata-rata waktu respon pengiriman data ialah 1-2 detik. Adapun waktu respon mengalami delay mencapai 2 detik apabila beberapa perintah kendali dilakukan pada waktu yang bersamaan.</strong></p><p> </p><p><strong><em>Kata Kunci - </em></strong><em>Smart Home</em>, Jaringan Sensor Nirkabel, Zigbee.</p><p> </p><p><em>Abstrak</em><strong> - Home security becomes very important when homeowners leave the house empty. In addition to theft, fire is also a problem that often occurs when the house left the owner. As an alternative solution to maintain and supervise the homes submitted in this study is to use Wireless Sensor Network technology integrated with the Internet network, so that homeowners can still monitor the state of the house remotely. In this study designed prototype smart home system or Smart Home which utilizes Wireless Sensor Network technology using Zigbee standard. Some sensor nodes are placed in the home equipment, where each node can communicate wirelessly and centrally at the coordinator node. Next node coordinate will be connected to the internet network so that homeowners can open smart home application anytime and anywhere. The Smart Home system design is simulated using a home model to test the performance of Smart Home devices. Smart Home performance testing begins with testing the accuracy of each sensor data until the communication response time from the sensor to the monitoring center. The error rate of temperature readings in each room is 1 - 4.27%. PIR sensor successfully detects the presence of people in a room with a delay time is 2.8 seconds with a maximum distance of 5 meters. The control and monitoring functions (on / off) of electronic devices work well, with a response time of less than 1 second. From the results of testing wireless communication between nodes, obtained that the maximum distance between nodes is about 20 m, with the average response time of data transmission is 1-2 seconds. The response time has a delay of 2 seconds if some control commands are done at the same time.</strong><strong></strong></p><p><strong> </strong></p><p><strong><em>Keywords - </em></strong> <em>Smart Home</em>, Jaringan Sensor Nirkabel, Zigbee.</p>

In the development of marine tourism, two kinds of impacts on the environment will emerge, positive and negative. The positive impacts include: (1) increasing accessibility and economic activities (2) increasing amenities, and (3) creating attractions. The negative impacts include: (1) pollution of the environment, change the quality of the environment. (2) change the original shape of the Marine tourism area, and (3) social impacts. When the development concepts have been realized and managed optimally, it will automatically have a major impact on improving the community’s economy in a sustainable manner in the future, which will open up large enough jobs. On the outside the region, the community can feel the positive impact of the development of tourism and economic improvement, because the community can also take the opportunity to try in the fields related to the development of marine tourism around the area. Conversely, it could only receive bad consequences from the development of marine tourism. It can be concluded, that there will be sustainable development if there is a balance between infrastructure development and human resource development. This research is part of a case study on the initial concept of structuring the Gampong Krueng Raya coastal area, Sabang City, NAD, from the socio-economic aspect. This research uses descriptive qualitative and interpretative methods. Data and information obtained by literature study and field observations.

The condition of limited infrastructure in Indonesia positions that current infrastructure is very important to be built immediately to support development in various fields so that economic, trade, industrial and other social activities run more smoothly and develop, so that the dynamics of society in all corners of the country will increase. The cost of producing electricity in Eastern Indonesia, such as Sulawesi, Papua, Maluku and Nusa Tenggara is currently 2 to 5 times the cost of producing electricity in Java, Bali and Sumatra. One of the ways that should be intensified is by building a small-scale Liquid Natural Gas (LNG) infrastructure concept that aims to meet the needs of gas consumers who do not receive gas pipelines or who require small volumes of gas, for example small capacity power plants, especially those in islands in Eastern Indonesia. In this archipelago, it is impossible for all regions to be connected by pipelines that cross the oceans, because of course it requires very large funds. The application of small-scale LNG technology is the right solution for LNG supply in Eastern Indonesia. If the energy infrastructure is available, the quality of human resources must also be improved so that they become human resources who are always active and always adapt to developments.
