Abstract

This paper examines the impact of the El Nino climate on changes in the phase of rainfed lowland rice in Gorontalo Regency. To see the impact of the El Nino climate (in 2015) well, the year for the absence of El Nino (in 2016) is used as a comparison. Landsat 7 and landsat 8 images were used to analyze the growth phase of rainfed lowland rice by combining NDVI and TCT methods. The results of this study indicate that there has been a shift in cropping patterns resulting in a shift in the growth phase of rainfed lowland rice. Seen in September 2015 until October 2015, most of the wetland conditions were in fallow conditions, which then continued until February 2016, but the extent of fallow land conditions has been decreasing since January 2016 to February 2016. Unlike in September 2016 Until October 2016, most of the land was in stagnant conditions which showed farmers were preparing to plant rice. Finally in December 2016 until January 2017, the rice phase has been in the reproductive phase and maturation phase, whereas in El Nino years only in January 2016 to February 2016 are in the reproductive phase and maturation phase.

Abstract

The purpose of this research was to analyze the land use change and identify the morphodynamics of the coastline at estuary in Batang Masang River from 2015 to 2021. These changes determined through remote sensing by utilyzing sentinel-2 satellite imagery in 2015 and 2021. Land use change known by using supervised classification with the maximum likelihood classification method. Meanwhile, to determine the morphodynamics of the coastline, doing by digitization on screen land use map based on the lowest tide from the bathymetry map. This study obtained results in form the largest change land use the addition of open land area of 27.64 ha, then followed by a reduction in forest land area of 12.26 ha, while the smallest change land use was the reduction of scrub was 7.73 ha (1.79 %). Furthermore, there was a reduction in the length of the coastline, namely 0.43 km, abrasion of 9.68 ha and accretion of 11.52 ha occurred. Thus the most dominant morphodynamics process in the Batang Masang River estuary is influenced by sea waves and river discharge.

Abstract

The reseach area administratively located in Budong-budong District, Mamuju Regency, West Sulawesi Province. The purpose of this study is to determine the provenance of sand sediments at Budong-budong River based on petrographic analysis of QFL (quartz, feldspar and rock fragments) components. There are seven representative samples namely HRN/BD-01, HRN/BD-02, HRN/BD-03, HRN/BD-04, HRN/BD-05, HRN/BD-06, HRN/BD-07 that will be observed by its optical properties. Based on genetic classification (Krynine, 1963, in Folk, 1980) and empirical classification (Folk, 1980) of quartz mineral grains, there are three types of quartz that can be identified; 1). Monocrystalline quartz with a sub-equant to elongated shape, dark straight to oblique waves (originally from granite and gneiss); 2). Composite polycrystalline quartz with sub-equant to elongated shape, straight dark to slanted wavy, straight and crenulated boundaries between crystals (derived from recrystallized metamorphic rocks); 3) Composite polycrystalline quartz with elongated shape, strongly wavy darkening, and straight/smooth, crenulated, and granulated inter-crystal boundaries (derived from depressed metamorphic rocks). The source rock of the reseach area based on point-counting result of quartz, feldspar and rock fragments on the Dickinson & Suczek (1979) QFL triangle diagram was interpreted as a recycled orogen type.

Abstract

The objectives of this study was to (1) analyze infrastructure damages (buildings and roads) due to liquefaction based on Open Street Map (OSM) data, (2) analyze spatial distribution patterns of infrastructure damage due to liquefaction, (3) analyze the characteristics of satellite imagery before and after liquefaction based on the time series (sentinel 2) satellite image index. The results showed that the Petobo was the most affected by liquefaction, with a percentage of damage in roads is 83.7% and buildings is 99.68%. Then the results was obtained from the spatial spread analysis of pattern have been analyzed and mapped with the heatmap method and the 100mmx100m grid method. The tendency of the distribution pattern of buildings (Petobo, Balaroa, and Jono Oge) follows the standard distance ellips method, while the distribution of buildings (Lolu) follows the standard distance pattern. Furthermore, the results of the spatial analysis of NDVI satellite images show the colors shading that indicate vegetation or the level of density (greening) on a land where the green color indicates the density on a land. While the results of the spatial analysis of NDWI images explain the distribution of colors that show humidity in a land.
