Abstract

Gempa bumi tanggal 11 April 2012 di Kota Banda Aceh dan sekitarnya masih menunjukkan minimnya persiapan masyarakat mengenai kesiapsiagaan menghadapi bencana. Penyebaran informasi dan pendidikan masyarakat terkait ilmu kebencanaan yang belum maksimal menjadi salah satu faktor penyebab. Minimnya persiapan dalam menghadapi bencana dapat dilihat dari kemacetan yang terjadi pada saat itu. Kemacetan terjadi di beberapa ruas jalan saat warga Kota Banda Aceh melakukan evakuasi akibat gempa bumi 11 April 2012. Jalur evakuasi dan titik evakuasi yang ada tidak memadai. Untuk menganalisa kejadian tersebut, survey dan observasi lapangan menjadi metode yang mungkin dilakukan dalam mengevaluasi kejadian darurat yang sudah terjadi. Masyarakat dan instansi terkait menjadi objek survey. Kajian yang berlokasi di Kecamatan Baiturrahman ini dilakukan dengan tujuan menentukan jalur evakuasi dan titik evakuasi alternatif. Kecamatan Kutaraja dan Meuraksa menjadi bagian dari kajian ini disebabkan sebagian warganya melewati Kecamatan Baiturrahman untuk melakukan evakuasi. Dari hasil survey tersebut didapatkan data pergerakan masyarakat pada gempa bumi 11 April 2012 yang lalu. Data tersebut kemudian menjadi acuan untuk observasi lapangan dan analisa tingkat pelayanan jalan (Level of Service, LoS). Berdasarkan data observasi dan analisa tersebut diketahui kelayakan suatu ruas jalan sebagai jalur evakuasi. Pada jalur evakuasi dengan LoS yang tidak stabil ditambahkan jalur alternatif untuk mereduksi kemacetan. Titik evakuasi vertikal menjadi variabel berikutnya untuk mereduksi kemacetan. Ruas-ruas jalan dan titik evakuasi vertikal tersebut kemudian menjadi peta jalur evakuasi alternatif Kecamatan Baiturrahman. Kata Kunci: Gempa Aceh 11 April 2012, Tingkat Pelayanan Jalan, Jalur Evakuasi, dan Titik Evakuasi Vertikal The earthquake on 11 April 2012 in the city of Banda Aceh and the surrounding communities still showed lack of preparation on disaster preparedness. Dissemination of information and education related to the science of disaster have not been up to be one of the causes. The lack of preparation for disasters can be seen from the congestion that occurs at that time. Congestion occurs on some streets as residents evacuate the city of Banda Aceh earthquake 11 April 2012. Evacuation routes and evacuation points are inadequate.To analyze these events, surveys and field observations become feasible method to evaluate emergency situation that has occured. Earthquake victims and stakeholders is the object of the survey. This study aims to create an alternative evacuation routes and evacuation points in sub-district Baiturrahman, Banda Aceh city. Kutaradja and meuraxa sub-district a part of the sudy, because of its population through the district baiturrahman when an earthquake to evacuate. The population movement data on the earthquake of 11 April 2012 were obtained from the survey. The data is used for a reference in the field of observation and to analyze the Level of Service. Based on the observational data and level of service can be determined the capacity of a road as evacuation road. Routes with unstable LoS, added alternate pathway to reduce congestion. Vertical evacuation points become next variable to reduce congestion. Roads and vertical evacuation point is then to be an Baiturrahman Sub-District alternatifve evacuation route map.

Abstract

Wacana pakan bouyancy pada pemeliharaan larva udang galah muncul karena dugaan untuk meratakan keberadaan pakan di kolom air dan memudahkan larva dalam menangkap pakan sehingga meningkatkan keseragaman ukuran larva pada D10 keatas, menekan laju kanibalisme, mempercepat grow rate dan meningkatkan survival rate. Percobaan ini dilakukan di bak di dalam hapa mini berukuran 100x100x50 cm selama 30 hari; menggunakan larva udang galah D7. Kepadatan tebar 200-300 ekor/L. Pakan bouyancy diberikan 3 kali/hari dengan takaran antara 10-30% bobot biomassa. Percobaan diulang 2 kali. Kajian pemberian pakan bouyancy dilakukan menggunakan bahan pakan berupa susu 150 gr, terigu 150 gr, telur 8 butir, minyak cumi 10 gr, cumi-cumi 150 gr, yeast 5 gr vit C 0,5 gr dan pewarna makanan. Untuk mengoptimalkan daya apung ekstrusi pakan dilakukan secara sederhana dengan menggunakan mixer dan reaksi dari yeast dan gula menghasilkan gas ke pori-pori pakan. Beberapa parameter yang diamati sebagai bahan konsiderasi dari aspek biologis antara lain daya apung pakan, keseragaman ukuran larva, laju pertumbuhan, umur larva, survival rate dan laju konsumsi. Dari hasil percobaan diperoleh daya apung pakan dikolom air bertahan paling lama satu jam. Keseragaman ukuran larva pada D10 keatas sebesar 70%, laju pertumbuhan tercepat diperoleh pada D14 dengan ukuran 10 mm (7%), umur larva yang tercepat masuk stadia Post Larva terjadi pada stadia D20 (5%) dan survival rate sebesar 40% yang dihasilkan selama masa pemeliharaan. Kata Kunci: Larva Udang Galah, Pakan Bouyancy dan Ekstrusi The discourse of bouyancy feed in the breeding of giant freshwater prawn larva appears to distribute evenly the feed in the water column and to ease the larva in catching the feed to improve uniformity of larva size from D10 to up, pressing its cannibalism, improving its grow rate and survival rate. This research was conducted in fairish micronet 100x100x50 cm for 30 days; using Larva Giant freshwater prawn larva (D7). The density of disperse was 200-300 larva/L. Bouyancy feed was given 3 times/day by measuring around 10-30% weight of biomass. It was repeated 2 times. Bouyancy feed was made of several materials, they are: 150 gr of milk, 150 gr of wheat, 8 pieces of egg, 10 ml of Squid oil, 150 gr Squid, 5 gr yeast, 0,5 gr of Vitamin C and food coloured. To optimize the exstrution of feed, it is conducted simply by using mixer and reaction of sugar and yeast yielded gas to pore the feed. Some parameters observed as biological aspects such as buoyancy feed, uniformity of larva size growth rate, age of larva, survival rate and consumption rate. The result showed that the buoyancy feed could survive for one hour. The uniformity of larva size at D10 to up was gained about 70%, the fastest growth rate was obtained at D14 at the size of 10 mm ( 7%), the fastest larvea age entering Post Larva stage occurred at stage D20 ( 5%). Survival rate gained during the treatment was 40%. Keywords: Giant freshwater prawn larva, bouyancy feed and ekstrution
