Abstract

The study of noise level distributions have been done in Baiturahman Mosque area. The measurement take place in different places (near the mosque), times and days. The point of the measurement is choosing based on the high appereance level of noise such as market, park and main road at surrounding of the mosque. The result shows that the average highest level is 82,3 dB and the lower is 58,6 dB.

Abstract

a b s t r a c tThe fire disaster was one of the disasters that frequently occurred in Indonesia. Fires often occur in particular in the area of dense population average is affected by the presence of shorting electric and gas leakage from household kitchens. many cases fires are known at the time of the fire, and little has happened can be detected early. Based on community-based information system that has been done today, then needed a fire disaster information systems that can provide information and notification in real-time in the form of initial conditions information from source fire and its location to the firefighter or the community effectively and efficiently. The purpose of the research was the design of a prototype fire information system building based Google Map using lines of communication the GSM module. The prototype was built using the DHT11 temperature sensor, Sensor Smoke MQ2, Arduino Uno, GPS module and GSM modem SIM9000. The research produces information systems monitoring fires in two systems namely fire detection system and information systems fire location based Google Maps. Both systems have been run in accordance with experiments that have been conducted resulting in fire occurrence data location information with data on the condition of the presence of smoke and temperature/temperature. And expected with this prototype development research community or parties associated with catastrophic fires can be helped to anticipate disasters and takes a lot of sacrifice.Keywords: Early Warning Systems, Fire, GSM, Google Maps, Arduino a b s t r a kBencana kebakaran merupakan salah satu bencana yang kerap terjadi di Indonesia. Kebakaran sering kali terjadi khususnya di kawasan padat penduduk yang rata-rata dipengaruhi oleh adanya korslet listrik dan kebocoran gas dari dapur rumah tangga. banyak kasus kebakaran diketahui pada saat sudah terjadi kebakaran dan sedikit dapat dideteksi lebih awal. Berdasarkan sistem informasi berbasis masyarakat yang telah dilakukan saat ini, maka diperlukan sebuah sistem informasi bencana kebakaran yang dapat memberikan notifikasi dan informasi secara real-time dalam bentuk informasi dari awal kondisi sumber kebakaran dan lokasinya kepada pihak petugas pemadam kebakaran maupun masyarakat secara efektif dan efesien. Tujuan penelitian adalah perancangan prototipe sistem informasi kebakaran gedung berbasis Google Map dengan menggunakan jalur komunikasi modul GSM. Prototipe dibangun menggunakan sensor suhu DHT11, Sensor Asap MQ2, Arduino Uno, modul GPS dan modem GSM SIM9000. Penelitian menghasilkan sistem informasi monitoring kebakaran dalam dua sistem yaitu sistem deteksi kebakaran dan sistem informasi lokasi kebakaran yang berbasis Google Maps. Kedua sistem telah berjalan sesuai dengan percobaan yang telah dilakukan sehingga menghasilkan informasi data lokasi terjadinya kebakaran beserta data kondisi adanya asap dan suhu/temperatur. Dan diharapkan dengan penelitian pengembangan prototipe ini maka masyarakat atau pihak terkait dengan bencana kebakaran dapat terbantu untuk mengantisipasi bencana yang lebih besar dan memakan banyak korban.Kata Kunci:Sistem Peringatan Dini, Kebakaran, GSM, Google Maps, Arduino

Abstract

Remote sensing makes it possible to map potential geothermal site for a large area effectively using thermal infrared. The purpose of the present research is to overlay ground temperature, resistivity and satellite retrieved temperature in identifying geothermal potential site in Jaboi, Sabang-Indonesia. The data of acquisition of the DEM imagery was January 3rd, 2009 and the Landsat 8 imagery is July 18th, 2017. The satellite data were applied to extract the land surface temperature and land classification across. Two supporting data in situ were used to validate the results from remote sensing. First dataset was ground temperature measurements with total 114 points and second dataset was vertical electrical sounding (VES) with total of 51 points. Satellite, VES and ground temperature data were processed and analysed using the Envi 5.3, PCI Geomatica 2016 and ArcMap 10.4. The results from each data were integrated to produce a map shows geothermal potential. Its integration produced four areas which were considered to have high geothermal potential. However, these areas vary in term of the clustering of the features of interest, for example lineament and drainage density of the area, high temperature in the surface area, fault existence and low resistivity subsurface. All the features must take into consideration to rank potential area which has higher potential. Finally, a map of geothermal potential across were successfully created as an insight for future reference.

Abstract

AbstractThis paper presents simulation on temperature distribution in two-dimensional laminar flow for single pelet thermal reactor with variation on temperature inlet and mass-flowrate. The OpenFoam platform (Simflow 3.1) has been used for the computational and numerical analysis. The simulation is carried out on a single pellet with an aspect ratio of 1.2. The variations in the mass velocity of the coolant flow are 10, 100 and 14.300 kg×s-1 with a constant coolant temperature of 552 K, and the variations of the input coolant temperature are 300, 552 and 1000 K with a constant mass-flowrate of 10 kg×s-1. The results obtained from the simulation show that for variations in the input coolant temperature of 300, 552 and 1000 K, the fuel temperature can be reduced respectively by 34, 26 and 14 K. At the fastest variation in the coolant mass-flowrate of 14.300 kg×s-1, the coolant temperature around the pellet rises by 396 K. The decrease in fuel temperature is significant if the mass-flowrate of the input coolant flow is relatively low.
