Abstract

Geology is an important aspect in the development of tourism in an area. One of the attractions in a natural tourism location is certainly highly controlled by the geological setting in the area. The purpose of this research is to assess tourism values of geological features in the Bongo and surrounding areas as a basis for developing geotourism on the southern coast of Gorontalo. The research location is at coordinates N 00029’42” - N 00029’51” and E 12301’26” - E 12303’32”. The method used in this study is a surface geological survey, which includes field data collection in the form of lithology, geological structure and geomorphology. The standard used for assessing tourism values is the technical guide for assessing geological heritage resources by the Geological Survey Center. The results showed that the lithology unit of the study area consists of granite, volcanic breccia and reef limestone. The geological structure in the research area is shear fracture with main stress that relatively directed to northwest-southeast. The geomorphic unit of the study area consisted of two units, namely volcanic hills, and marine units. The results of the assessment of tourism values on geological features explain that the Bongo and surrounding areas are included in the medium category. Improvements are needed on low value criteria, namely vulnerability, relationships with other values, and economic level.

Abstract

Regionally, the research area is composed of volcanic and plutonic rocks. Stratigraphic data of the study area are still regional scale. This study aims to analyze detailed stratigraphic data and formulate the geological history of the Limbato area and its surroundings. The area located at coordinates 0º56’6” - 1º0’10.8” N dan 122º5’56.4” - 122º9’10.8” E, the area of the study is around 45 km². The method used in the research is scientific exploration by conducting a surface geological mapping survey. The geological surface in the form of field data collection and laboratory analysis. Field data in the form of lithology data and laboratory analysis in the form of petrology and petrographic analysis. The stratigraphy of the research area is divided into 4 (four) unofficial units, which are sorted from old to young, namely granodiorite units of Middle Miocene age, volcanic breccia units of Late Miocene to Early Pliocene, andesite units of Middle Pliocene and alluvial units of Holocene age.Stratigraphic analysis of the Limbato area is related to geological history. In the Middle Miocene period subduction formed plutonic rocks that produced granodiorite units, then during the Late Miocene volcanic eruptions resulted in volcanic breccia units. The activity was stopped at the time of the Early Pliocene. After the volcanic activity was stopped, then new magma activity occurred at the time of the Middle Pliocene resulting in an andesite unit. After all rock units have been deposited, an erosion process occurs in older units which results in an alluvial unit.

Abstract

Batulayar is one of the small watersheds contained in the Limboto / Large watersheds. Where the Limboto watershed as a whole is in the category of drought prone (Ayuba dkk, 2018). The aim of this study; know the availability of the Batu Layar Watershed through SWAT modeling. The method used in this study is the Soil and Water Assessment Tool (wateryield parameter / WYLD) to obtain water availability data. Based on the results of the SWAT analysis, Sub Basin 45 has the largest WYLD value of 626.5 mm, which is administratively located in Molanihu Village. While Sub Basin 32 is a sub basin with the smallest WYLD value of 421.5 mm and administratively this sub basin is located in Pangadaa Village. The value of water which is the result of the accumulation of surface, lateral, and base flow where these three flow patterns determine further planning related to handling the problem of water availability. This indicates that Pangadaa Village has a deficit in water availability when compared to other villages. This needs to be controlled for the conversion of land functions considering that this area is used as dry land agriculture by the community which can result in the threat of water management in this sub basin.

Abstract

Ilmu geografi adalah salah satu ilmu yang mempelajari mengenai fungsi suatu wilayah. Seiring perjalanan waktu geografi mengalami perkembangan pesat, salah satunya adalah geografi ekonomi. Geografi ekonomi adalah salah satu disiplin ilmu geografi yang mempelajari mengenai proses kegiatan ekonomi suatu wilayah dan pengaruhnya terhadap wilayah lainnya. Geografi ekonomi dimulai pada awal abad ke-20 oleh Alfred yang meneliti mengenai aglomerasi keterlibatan manusia dalam proses industrialisasi. Pada masa Alfred juga seorang pakar ekonomi, Walter membuat disertasi mengenai Location and Space-Economy menjelaskan bahwa faktor ruang mempengaruhi ekonomi. Dari disertasinya ini terbentuklah ekonomi regional. Jika dibaca secara harfiah, geografi ekonomi dan ekonomi regional memiliki arti yang sama, yaitu membahas ekonomi dalam bentuk suatu ruang. Faktanya, terdapat perbedaan antara keduanya. Tujuan dari penelitian ini dengan menggunakan metode kualitatif membahas mengenai perbedaan ekonomi regional dengan geografi ekonomi. Hasil dari penelitian ini menyatakan bahwa terdapat perbedaan sudut pandang antara ekonomi regional dan geografi ekonomi. Ekonomi regional yang dikemukakan oleh Walter lebih membahas ekonomi secara sektor analisis tanpa menarik kesimpulan mengenai pola spasial suatu wilayah. Sedangkan geografi ekonomi menganalisis ekonomi berdasarkan titik-titik garis kesamaan nilai ekonominya.

Abstract

Coral reef mapping aims to see the distribution of coral reefs from 2000, 2010 and 2020. In addition, coral reef mapping also aims to see changes in the extent and damage of coral reefs from 2000, 2010 and 2020. The method used to detect the distribution of coral reefs is lyzenga logarithmic method, while to detect damage to coral reefs the method used is the unsupervised classification method. The lyzenga logarithm method uses attenuation coefficients based on the sharpening of the pixel spectral value to a certain depth to increase the value of the reflection of coral reef objects and the unsupervised classification method uses the sensitivity of the spectral values ​​of each pixel to coral reef objects. The results of the interpretation there was a significant change in the area of ​​coral reefs from 2000 to 2010 and 2010 to 2020. The interpretation of images from 2000 to 2010 detected a decrease in the area of ​​1.19 hectares. In 2010 to 2020 it detected a decrease in area of ​​28.87 hectares. The classification results detected an increase in the area of ​​damaged coral reefs from 2010 to 2020 as much as 8.74 hectares. The two methods used have differences in the level of accuracy, the lyzenga logarithmic method has an accuracy rate of 88.89% while the unsupervised classification method shows an accuracy of 86.12% so the lyzenga logarithmic method is the most suitable method for detecting coral reefs in Suwarnadwipa, Bungus Teluk District. Kabung City of Padang.

Abstract

An analytical study is conducted on the potential of wind energy in Gorontalo Province for wind plant development considering that many developing countries had done so. Wind speed in each region in Gorontalo Province was statistically analyzed, identified potential areas, and calibrated wind speed to wind power density. Based on KTA value it results 3 category, namely good (20 watt/meter2 - 23 watt/meter2), enough (12 watt/meter2 - 20 watt/meter2) and poor (7watt/meter2 - 12 watt/meter2). Then only the KTA value in the good and enough category are used as the land suitability standard. Multi criteria used here is buffering technique by giving a distance between land that can be built by wind plant and land that cannot be built by wind plant. There are 6 layers used in multi criteria, 4 layers use buffering techniques (land use and land cover, land sanctuary, road and public transport terminal), while the other 2 are reclass (lereng and KTA). GIS is used for mapping the distribution of land suitability with the overlay and separation method. The results, total area of land suitability start from 1 hectar until 3.413 hectars. There are ten sub-disctricts which have land suitability more than 1.200 hectars, namely Kwandang, Dulupi, Anggrek, Bongomeme, Tibawa, Pulubala, Wonosari, Sumalata, Boliyohuto and Paguyaman (largest to smallest).

Abstract

Kota Padang memiliki tingkat kepadatan penduduk tinggi, dengan jumlah penduduk 973.152 jiwa pada tahun 2020 dan tingkat Kepadatan 1.400 Jiwa/Km2. Tidak semua kawasan dapat diperuntukan untuk permukiman. Beberapa wilayah yang memiliki kepekaan lingkungan tinggi terhadap perubahan atau peralihan fungsi lahan. Penelitian ini difokuskan terhadap daya dukung lahan perkotaan yang berbasis kepekaan terhadap lingkungan. Faktor yang menjadi penentu adalah, ketinggian, kelerangan, jarak dari area permukiman, jarak dari jalan utama, kepadatan penduduk, kawasan lindung, cagar budaya serta kawasan resiko bencana. Metode digunakan adalah GWR yang dapat mencari hubungan antar variabel serta pembobotan untuk sumbangan variabel dalam mempengaruhi tutupan lahan. Perbandingan Fhitung dan Ftabel dari pengujian regresi membuktikan bahwasanya untuk daya dukung lahan model GWR lebih baik dari model regresi biasa. Dari hasil overlay setiap variabel didapatkan hasil area tidak sensitif seluas 6%, Sensitif Ringan 19%, Cukup Sensitif 22%, dan Sangat Sensitif 54% dari total keseluruhan luas Kota Padang 692 Km2.
