Abstract

Indonesia is located in The Pasific Ring of Fire or in the circle of active fire mountains in the earth. As a result, the volcanic activity and its underground eruption cause a lot of earthquakes which is followed by tsunami. Earthquake and tsunami caused thousand people die and a lot of people lost their wealth. Unfortunately, Indonesian people are still weak in case of preparation from disaster. In other words, disaster preparation in this discussion refers to the ability and awareness of Indonesian people to save their lives when disaster comes. However, preparation itself can be devided into simulation, survival training and guidance in order to avoid building’s crash. As a result, it increasing the ability of residents to survive from disaster. Furthermore, the characteristics of disaster contains of rescue preparation, the competence to struggle, plaining and recovering. Meanwhile, dimension of survival can also be differ into: (1) rescue information, (2) synchronize coordinate management, (3) formal and informal organinization, (4) Rescue team whose prepared to run their duty during emergency time, (5) survival recovering, (6) wealth recovering, (7) main function during emergency and recovering times and (8) recovering activity. Finally, the preparation gives awareness and belief among communities to rescue from disaster. Moreover, it help to minimize sufferer and its psychological impact.Keywords ; preparation from disaster

Abstract

Infeksi saluran pernapasan akut (ISPA) merupakan kasus yang sering ditemukan padaanak. Diperkirakan 0,5%-10% ISPA mengakibatkan komplikasi sinusitis. Sinusitis adalahinfeksi sinus paranasal dengan gejala ISPA yang menetap atau makin berat dalam kurunwaktu tertentu. Tiga faktor yang berperan dalam terjadinya sinusitis adalah ostium yangtertutup, penurunan jumlah atau fungsi silia serta berubahnya viskositas sekret. Dengananamnesis dan pemeriksaan fisik yang teliti dapat ditegakkan diagnosis sinusitis akutpada anak. Pada sinusitis kronis, CT scan merupakan alat bantu diagnosis yang dapatdipercaya. Diagnosis banding antara lain cystic fibrosis dan inverted papilloma. Padaumumnya sinusitis dapat sembuh dengan terapi medikamentosa. Amoksisilin merupakanantibiotik utama disertai dengan pemberian antihistamin, nasal dekongestan dan steroid.Anak yang tidak memberikan respon dengan terapi medikamentosa yang maksimal ataudengan komplikasi dapat dilakukan tindakan pembedahan.

Abstract

Tsunamis are ocean waves that can be caused by earthquakes, landslides or volcanic eruptions that occur at sea either vertically or horizontally. Population of Padang city, which is more than half the population living in areas relatively close to the beach. A large of population living and indulge in the coastal of Padang city caused an increasing vulnerability of the population to the dangers of tsunami. Effective evacuation planning is an effort to minimize the possible impact of the tsunami will occur. The research methodology consists of three phases: data collection, data analysis stage of the process network analisys in ArcGIS software and the third is the analysis phase. Service area is generated using a network analyst tool. Service area in this research means that the minimum area that can be reach by evacuee before tsunami come. The results show that the shelters are not able to cover all of the areas in tsunamiprone zones. The results show that the shelters allocated by KOGAMI and DKP can not cover about 9.5% and 10.9% evacuee in tsunami prone area respectively. To overcome this, the addition of potential new shelter building must be allocated in non covered service area.  Keywords: tsunami, evacuation, shelter, network analyst, service area

Abstract

The availability irrigation and drainage systems had to experience a reduction in capability and performance. This is due to lack of maintenance and monitoring for the beginning so it works out of its capacity limit, the low performance of Operations and Maintenances (O & M), deficiency and deteriorating services. Since 2015, the irrigation area Sei Silam has no O & M because of the transfer ofauthority which is from Kampar district government to Riau provincial government. Therefore, it is necessary for evaluating the performance index of facilities and infrastructure in the main irrigation area based on Minister of Public Work Regulation Number 12/PRT/M/2015 which has been interpreted into IrrigationSystem Performance Index (Indeks Kinerja Sistem Irigasi – IKSI). Result of research showed that the performance index is 71.30%or condition of performance is good; where physical infrastructure is in the amount of 31.98%; plantation productivity is equal to 13.02%; supporting facility is 7.7%; personnel organizationis equal to 9.6%; 5% of documentation; also there is 4% in Water User Farmer Association.Keywords: performance index, irrigation, IKSI

Abstract

Physical model research of water wheel for agricultural irrigation is executed at Hidrotechnic’s Laboratory University of Riau. Model that is utilized doesnt utilize model scale, but phenomenon of prototype will be represented by model that made. Water wheel bases executed field study previous, having alone uniqueness. Paddle wheel lap speed one every minute (RPM) and debit who can be lifted by waters jacking tube visuals are relative stable. Even so was known it must be water wheel condition be still get improved debit that can be lifted by waters jacking tube. Water wheel model is undershoot water wheel made bases prototype aught at the site or at agricultural location. This waterwheel is made at Technicals Engineering Material Laboratory. This Waterwheel model specification with diameter 55 cm, broad 6 cm, long fan 6 cm, total fan 18 numbers and heavy 1,764 kg. The research did by variated foots up and tube dimension so gotten by water wheel model with tubed optimal one. Variation of tube is 3, 6, 9 and 18 numbers with each volume saves 3,4 ml, 8,0 ml, and 16,8 ml whereas debit flows are not variated.Result of this experiment showing that Waterwheel speed regarde by flow speed that punches waterwheel fans, but relationship both is not linear. Total tube and tube volume regard paddle wheel lap. Diameter 0,8 cm tube can’t lift waters because the diameter of tube are too small but diameter 1,3 cm and 1,7 cm tube both can lift flows.Maximum debits which diameter 1,3 tube can be lifted by jacking tube is 6,39 ml/dt, it happens upon tube amount 18 numbers whereas on diameter tube 1,7 cm maximum debits is 5,38 ml / dt happens upon tubed amount 6 numbers.Keywords: Model, Waterwheel, Undershot
