Abstract

AbstractThe earthquake and tsunami disaster that occurred in Aceh Province had a major impact on infrastructure such as infrastructure damage, building collapse, and structural damage to buildings. Lessons from the disaster have changed the public understanding of good and safe building structures, by considering the earthquake-resistant design of building. The scope of this research is related to the selection of the right and safe foundation. This study aims to find out the right steps in deciding to determine which foundation is suitable for use, by considering the safety of the surrounding community. This research is located in the construction of the Batoh Health Center Building in Banda Aceh by looking at the appropriate criteria in determining the alternative choices of the earthquake-resistent design of foundations using the AHP (Analytical Hierarchy Process) method. The criteria used in determining alternative foundation selection are economic aspects, implementation aspects, environmental aspects, soil conditions, and field conditions. The types of foundations that are used as an alternative choice are hydraulic jack-in system pile foundations, bored pile foundations, and the foundation of the cobwebs (KSLL). Based on the results of the study, the criteria weight values were from the highest to the lowest order, namely the soil condition aspect 0.51, the economic aspect 0.27, the implementation aspect 0.12, the environmental aspect 0.06, and the field condition aspect 0.04. The alternative choice of the right foundation for use in the construction of the Batoh Health Center UPTD Building in Aceh Province is the cobweb construction foundation (KSLL), with the priority order of the alternative choices namely the Cobweb Foundation (KSLL) 0.58, the drill system pile foundation (Bored Pile) with a weight of 0.22 and the last is the foundation of a hydraulic jack-in system of 0.19Keywords:foundation selection; AHP method; earthquake-resistant.__________________________ AbstrakPengalaman yang telah dialami oleh masyarakat khususnya pada Provinsi Aceh terhadap bencana gempa dan tsunami seperti kerusakan infrastruktur, keruntuhan bangunan dan kerusakan struktural bangunan. Belajar dari pengalaman tersebut, maka telah mengubah pandangan masyarakat dalam penanganan pembangunan struktur bangunan yang baik dan aman, dengan mempertimbangkan kondisi bangunan yang ramah gempa. Maka dari itu dilakukan penelitian mengenai pemilihan pondasi yang tepat dan aman. Penelitian ini bertujuan untuk mengetahui bagaimana langkah yang tepat dalam mengambil keputusan untuk menentukan pondasi mana yang layak dipakai, dan juga mempertimbangkan keamanan masyarakat disekitar. Lokasi penelitian pada pembangunan Gedung Puskesmas Batoh Banda Aceh dengan melihat kriteria-kriteria yang sesuai dalam menentukan alternatif pilihan pondasi ramah gempa dengan menggunakan metode AHP (Analytical Hierarchy Process). Adapun kriteria yang digunakan dalam menentukan alternatif pemilihan pondasi yaitu aspek ekonomis, aspek pelaksanaan, aspek lingkungan, kondisi tanah dan kondisi lapangan. Jenis pondasi yang menjadi alternatif pilihan adalah pondasi tiang pancang sistem hidrolik (hydraulick Jack In), pondasi tiang sistem bor (Bored Pile) dan pondasi Sarang laba-laba (KSLL). Berdasarkan hasil penelitian didapat nilai bobot kriteria dengan urutan paling tinggi hinga paling rendah yaitu kondisi tanah 0,51, aspek ekonomis 0,27, aspek pelaksanaan 0,12, aspek lingkungan 0,06 dan aspek kondisi lapangan 0,04. Untuk alternatif pilihan pondasi yang tepat untuk digunakan dalam pembangunan Gedung UPTD Puskesmas Batoh Provinsi Aceh adalah pondasi konstruksi sarang laba-laba (KSLL), dengan urutan prioritas alternatif pilihan yaitu pondasi Sarang laba-laba (KSLL) 0,58, pondasi tiang sistem bor (Bored Pile) dengan bobot 0,22 dan yang terakhir adalah pondasi tiang pancang sistem hidrolik (hydraulick Jack In)  0,19.Kata Kunci:Pemilihan pondasi; Metode AHP; Ramah Gempa;

Abstract

Abstract: In the city of Meulaboh, Aceh Barat Regency, there are a total of 12 tsunami disaster evacuation routes, with 7 evacuation routes in Johan Pahlawan District and 5 in Meureubo District. Several road segments serving as evacuation routes are located in the city center, often experiencing traffic congestion due to the high volume of public movement. To address this issue, research is needed to measure the community's satisfaction with the evacuation services to determine their effectiveness. Data collection will involve distributing questionnaires. The satisfaction variables assessed include tangible evidence (tangibility), reliability, responsiveness, assurance, and empathy. In Johan Pahlawan District, the tangibility variable indicates that the majority of the community agrees with the physical condition of the evacuation routes. However, concerns arise regarding side obstacles, intersections, and traffic lights, with approximately 51.6% of respondents expressing disagreement. The reliability variable shows a high level of agreement regarding the stability of the evacuation routes, while the responsiveness variable indicates that most residents disagree with their understanding of evacuation maps, the scarcity of evacuation signs, and the lack of information about temporary evacuation buildings. Although the assurance variable receives high approval, the empathy variable reflects a lack of trust in the government's role in publicizing evacuation routes. In Meureubo District, the tangibility variable demonstrates a positive assessment of 67.95%, indicating that the physical condition of the evacuation routes is considered adequate. Regarding reliability, 64.6% of the community has high confidence in the stability of the evacuation routes. However, the responsiveness variable, with an average of 46.73%, reveals that most residents have not seen evacuation maps, there is a shortage of evacuation signs, and there is insufficient information from the government about temporary evacuation buildings.Keywords : Evacuation Routes; Community Perception; Service EffectivenessAbstrak: Terdapat 12 jalur evakuasi bencana tsunami pada Kota Meulaboh Kabupaten Aceh Barat, di mana 7 jalur evakuasi Kecamatan Johan Pahlawan dan 5 Jalur Evakuasi Kecamatan Meureubo. Beberapa ruas jalan yang menjadi jalur evakuasi berada di pusat kota, sering terjadi kemacetan lalu lintas yang disebabkan oleh besarnya volume pergerakan masyarakat. Berdasarkan permasalahan tersebut perlu dilakukannya penelitian untuk mengukur tingkat kepuasan masyarakat terhadap pelayanan jalur apakah sudah efektif atau tidak. Pengumpulan data dengan pembagian kuesioner. Adapun variabel penilaian kepuasan masyarakat terhadap jalur evakuasi adalah bukti fisik (tangibility), Kehandalan (reliability), ketanggapan (responsiveness), jaminan (assurance) dan empati (empathy). Pada kecamatan Johan Pahlawan variabel bukti fisik (tangibility) menunjukkan sebagian besar masyarakat setuju terhadap kondisi fisik jalur evakuasi. Namun, terdapat kekhawatiran terkait hambatan samping, simpangan, dan lampu merah yang dapat menghambat proses evakuasi sekitar 51,6% responden menyatakan ketidaksetujuan. Variabel kehandalan (reliability) tingkat persetujuan tinggi terhadap mantapan jalur evakuasi, variabel daya tanggap (responsibility) menunjukkan sebagian besar masyarakat kurang setuju terkait pemahaman terhadap peta evakuasi, minimnya rambu-rambu evakuasi, dan kurangnya informasi mengenai gedung evakuasi sementara. Meskipun variabel jaminan (assurance) mendapat tingkat persetujuan yang tinggi, variabel empati (empathy) mencerminkan kurangnya kepercayaan pada peran pemerintah dalam sosialisasi jalur evakuasi. Sedangkan kecamatan meureubo variabel bukti fisik (tangibility) menunjukkan penilaian positif 67,95%, menandakan bahwa kondisi fisik jalur evakuasi dianggap memadai. Pada variabel kehandalan (reliability) 64,6%, masyarakat memiliki keyakinan tinggi terhadap kemantapan jalur evakuasi. Namun, pada variabel daya tanggap (responsibility) dengan rata-rata 46,73%, ditemukan bahwa sebagian besar masyarakat belum melihat peta evakuasi, rambu-rambu evakuasi masih kurang, dan kurangnya informasi dari pemerintah mengenai gedung evakuasi sementara.Kata kunci : Jalur Evakuasi; Persepsi Masyarakat; Efektivitas Pelayanan

Abstract

Kuta Alam Subdistrict is one of the Districts which are prone to tsunami disaster, 5 Gampongs from 11 Gampongs in Kuta Alam Sub-district are Gampong in the red zone, namely Gampong Lampulo, Gampong Lamdingin, gampong Lambaro Skep, Gampong Mulia, and gampong Peunayong. Based on the level of vulnerability, the five Gampongs are included in the Village which has a very high risk of tsunami. The main strategy to reduce disaster risk is to reduce casualties, namely by evacuating residents in vulnerable areas before the tsunami wave arrives in the area. Vertical evacuation is an evacuation carried out by moving residents from exposed areas by utilizing tall buildings or hills around vulnerable areas as evacuation sites. The feasibility of evacuation can be seen from the feasibility of the route, the feasibility of alternative evacuation buildings, travel time, and the mode used. From the analysis, it was found there is 11 alternative evacuation buildings can be used as evacuation buildings, where all buildings are declared feasible, and 11 evacuation routes, where only 1 route is declared feasible to be taken by vertical evacuation, while the other 10 routes are not feasible to walk
