Abstract

Indonesia including the earthquake-prone areas because Indonesia is situated between three tectonic plates and in the Maluku island it self has a fault line 10 zones, the impact of frequent tectonic earthquake on the island of Maluku resulted in a domino effect, such as the frequent occurrence of soil landslides at several points in the city of Ambon, and due to faults that occur lead ease rising sea levels to population centers so Ambon was becoming flooded. This research aims to design and analyzing measurements of earthquake monitoring system indication and landslides integrated via Wireless Sensor Network (WSN) by implementing a star topology, technology, ZigBee, WiFi technology Shield and GPRS (General Packet Radio Service). Researchers technology utilizes Wireless Sensor Network (WSN) to acquire and distribute widely the data to be monitored and controlled centrally.By detecting suspicious indicators such as tremor or landslides through nodes or end devices, the system provides information to the number of monitors and warnings. The system can also be accessed in real-time via the website by accessing the IP address of the Wireless-LAN devices Wi-Fi Arduino Shield.

Abstract

Groundwater availability in small islands with limestone is generally low. In order determine the availability and quality of groundwater, geoelectrical measurements were carried out with the Schlumberger electrode configuration on two tracks of Dulah Laut 1 and Dulah Laut 2. The results showed that the rock resistivity in Dulah Laut Village ranged from 27.4 – 1561 Ωm. Groundwater at the Dulah Laut 1 and Dulah Laut 2 were found at a depth of 5.21 m and 7.93 m below ground surface, respectively. The groundwater potential zone with resistivity of less than 150 Ωm was found at a depth of 4 m below the  surface. Groundwater quality was classified as moderately polluted with high salinity.

Abstract

Research on Land Evaluation for Residential Development in the Telaga Kodok Hamlet area has been conducted with the aim of determining the suitability classes of residential land and identifying limiting factors. The land characteristics studied include slope, effective depth, flooding and ponding, drainage, rock, and soil texture. The weight of each characteristic was analyzed using the Analytic Hierarchy Process (AHP). The analysis results indicate that there are 112.07 hectares (29.94%) of highly suitable residential zones, 166.67 hectares (44.53%) of moderately suitable zones with limiting factors such as moderate depth, poor drainage, and fine texture; 92.03 hectares (24.59%) of marginally suitable residential zones with limiting factors like steep slopes and fine texture; and 3.55 hectares (0.94%) of zones unsuitable for residential development.

Abstract

Research on rock resistivity and slip surface in the Ambon Volcanic Rock formation has been carried out through geoelectric mapping with the Wenner-Schlumberger configuration in the Kayu Putih area, Ambon City as one of the areas prone to landslides. Measurement of rock resistivity by Mapping was carried out on two tracks each 120 m long and 70 m long intersecting each other. The results showed that the resistivity values ​​of the rocks ranged from 185 Ωm to 4,128 Ωm consisting of Top Soil, Unsaturated Landfill, and Loose Sand as the cover layer followed by Dry Sandy Soil and Gravel, and Breccia Dacite and Tuff at the bottom layer. Breccia Dacite rocks with a resistivity of greater than 2,000 Ωm are found at a depth of 11 – 13 m below the soil surface functioning as slip surface for the sand layer above them. The movement of the soil mass over the slip surface causes cracks in the surface of the road and houses.

Abstract

This study was conducted to determine the lateral and vertical distribution of material resistivity values on Poka alluvial plain using electrodes with Wenner-Schlumberger configuration. Mapping is carried out on 2 lines each 120 m long with the smallest space of 10 m. The results showed that the resistivity of the material ranged from 48.8 Ωm to 2.247 Ωm spread laterally with a depth of up to 26.2 m. Loose Sand material occupies the upper layer, followed by the Alluvium and Sand layers in the middle, and Sand and Water which are unconfined aquifers in the lower layer.

Abstract

Penelitian ini bertujuan mengevaluasi faktor pembatas kesesuaian lahan untuk pengembangan agroekowisata, menilai kesesuaian lahan bagi komoditas tanaman pilihan, serta merumuskan arahan pengembangan agroekowisata yang berkelanjutan di hulu DAS Batu Gajah, Kota Ambon. Kelas kesesuaian lahan ditentukan menggunakan metode Analytical Hierarchy Process (AHP), sedangkan evaluasi kesesuaian komoditas (nenas, salak, durian, dan duku) didasarkan pada persyaratan tumbuh masing-masing tanaman. Hasil penelitian menunjukkan lahan terbagi dalam dua kelas, yaitu Cukup Sesuai (S2) seluas 113,43 ha (33,9%) dengan pembatas ketersediaan objek wisata, dan Hampir Sesuai (S3) seluas 220,90 ha (66,07%) dengan pembatas tambahan pada aspek pengelolaan. Dari empat komoditas yang dianalisis, nenas terpilih sebagai unggulan dengan kelas S3 seluas 172,84 ha (51,7%) dan faktor pembatas curah hujan dan kemiringan lereng, sementara 161,49 ha (48,3%) tergolong Tidak Sesuai (N) akibat kemiringan lahan curam. Arahan pengelolaan menekankan pengembangan agroekowisata berbasis komoditas nenas. Strategi yang direkomendasikan meliputi pembangunan peningkatn sarana-prasarana wisata, optimasi lahan sesuai kondisi fisik, dan pelibatan masyarakat.
