The VULNERABILITY OF SALT FARMER HOUSES IN DONGGOBOLO VILLAGE DUE TO CLIMATE CHANGES
Get PDFThis study aims to determine the vulnerability of salt farmer households due to climate change in Donggobolo Village. Weather anomalies resulting from climate change causes floods and droughts which negatively affect household livelihoods. The method for assessing the vulnerability of salt farmer households in this study is the LVI (Livelihood Vulnerability Index) analysis, LVI-IPCC, and descriptive analysis. LVI analysis uses seven components of vulnerability which include climate variability, food, water, health, socio-demographic profile, livelihood strategies, and social networks. The calculation of the overall value of the LVI components shows that the salt farmer household in Donggobolo Village is closer to the scale value for the most vulnerable conditions, with an index value of 0.333. The value of the climate variability component is the dominant value in the LVI, which is equal to 0.759. Based on the grouping of the seven LVI indicators into the IPCC vulnerability components (exposure, adaptive capacity, and sensitivity), the final score is 0.172. The large value of exposure compared to adaptive capacity causes household conditions to be closer to vulnerable conditions.
 
Spectral Pattern of Paddy as Response to Drought Condition: An Experimental Study
Get PDFEvery single physical object has a different response to the electromagnetic wave emitted to it. The response is in the form of how it absorbs and reflects the energy in every range of wavelength. The absorption and reflection curve is known as a spectral pattern. The spectral pattern of each object can be used to determine the object. In agriculture, the spectral pattern of plants can be used to determine the health condition of the plant. Drought is one factor that can affect the health of the plant. By identifying the spectral pattern of the plants, the effect of drought on paddy can be identified. This experimental study tried to identify the spectral pattern of some varieties of paddy and different growth stages. A spectrophotometer with a wavelength range of 350-1052 nm was used. Four varieties of paddy were planted in a greenhouse and being treated in drought conditions from the stage of vegetative, generative, and reproductive. Based on the result, the spectral response from the generative phase of all varieties gave the most different pattern compared to the control. This result compromising the rapid detection of paddy fields affected by drought using optical remote sensing data. Especially for plants in the stage of generative

Get PDFKebakaran hutan dan lahan (Karhutla) merupakan sebuah bencana lokal dan nasional tahunan yang ada di Indonesia. Kebakaran hutan dan lahan secara garis besar dipengaruhi oleh dua faktor, yaitu terjadi karena alami (Natural forcing) dan/atau aktivitas manusia (Anthropogenic forcing). Aktivitas manusia tersebut melepaskan sejumlah besar karbon dioksida (CO2), karbon monoksida (CO), metana (CH4), oksidanitrat, nitrogen dioksida (NOx) dan partikulat yang bertindak sebagai sumber pemanasan rumah kaca yang telah dipantau oleh satelit beberapa tahun terakhir. Penelitian ini mengkaji luas karhutla dalam beberapa dekade terakhir akibat pengaruh faktor antropogenik di Kalimantan menggunakan dua jenis kelompok data yang akan dianalisa yaitu data tanpa dan dengan komponen antropogenik. Analisa dilakukan dengan memanfaatkan data luaran CMIP5. Studi ini menggunakan pendekatan statistik teknik Random Forests (RF) untuk mengevaluasi kontribusi faktor iklim dan antropogenik terhadap luas karhutla di daerah Kalimantan. Kondisi umum luas karhutla berdasarkan data observasi yang diperoleh dari data GFED. Dua luas tertinggi yang terjadi di Kalimantan selama periode 1997 hingga 2005 terjadi pada tahun 1997 dan 2002 Menurut ketiga model pada tahun 1997 dan 2002 terlihat bahwa faktor antropogenik memberikan pengaruh lebih dominan terhadap luas karhutla di Kalimantan. Pada tahun 1997 dan 2002 luas karhutla akibat pengaruh antropogenik bernilai positif (menyebabkan luas karhutla meningkat).Forest and land fires are an annual local and national disaster that occurs in Indonesia. Forest and land fires are influenced by two factors, are natural forcing and /or anthropogenic forcing (human activity). Human activity releases large amounts of carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), oxidantrates, nitrogen dioxide (NOx) and particulates which act as sources of greenhouse warming that have been monitored by satellites in recent years. This study will examine the burn area of forest and land fires in recent decades due to the influence of anthropogenic factors in Kalimantan using two types of data groups to be analyzed, namely data without and with anthropogenic components. Analysis by utilizing output data from the CMIP5. This study uses a statistical approach to the technique of Random Forests (RF) to evaluate the contribution of climate and anthropogenic factors to the extent of forest and land fires in the Kalimantan region. General conditions of forest and land fires are based on observational data obtained from GFED data. The two highest areas that occurred in Kalimantan during the period 1997 to 2005 occurred in 1997 and 2002. According to the three models in 1997 and 2002 it was seen that anthropogenic factors had a more dominant influence on the extent of forest and land fires in Kalimantan. In 1997 and 2002 the extent of forest and land fires due to anthropogenic influences was positive (causing extensive forest and land fires to increase)
