The effects of climate change on agriculture and food security
Get PDFBackground: Climate change is an environmental issue that affects a lot of human activities and causes damages to the Earth which of course will have linkages to the living creatures’ life. Agriculture is a part of human activities that becomes a source of human life and influences food security. It also contributes to generating oxygen (O2) and absorbing carbon dioxide (CO2) in the air. As climate change is getting uncertain each time and influenced by some factors that make climate change getting worse, this gives some impacts on agriculture and food security. Besides, there will be other issues that come from agriculture and food security matters due to climate change, such as hunger due to food crisis, etc. Thereupon, we need to know the effects of climate change on agriculture and food security to mitigate and adapt to climate change. The objective of this literature study is to elucidate the impacts of climate change on agriculture and food security to understand the things that should be done to tackle the possibilities of bad impacts on human life. Methods: The method that was implemented was a qualitative method that utilized literature review to do the identification, evaluation and collecting information that was needed. Some papers and journals related to climate change, agriculture, and food security were used in literature review. Findings: Food production from crops and livestock is crucial for global food security. However, significant challenges to food production arise due to climate change and related factors. Heat exposure significantly affects livestock performance and welfare. Climate change also leads to soil erosion, resulting in decreased soil productivity, loss of carbon and organic nutrients, and reduced soil fertility. Conclusion: It is suggested to comprehend the effects of climate change on agriculture that will influence food security along with the well-being of people in running life
Analisis model pembangunan pertanian di Desa Jaten Kecamatan Jaten Kabupaten Karanganyar
Get PDFBackground: The ongoing development of agriculture has not succeeded in elevating farmers and agriculture to their proper position. The gap in the welfare of farmers compared to workers in other sectors is indeed widening. Findings: Progress in the agricultural sector will be realized if development planners, in this case the government, are serious about managing the existing natural potential and can improve the welfare of agricultural managers. Agricultural modernization is absolutely necessary for progress in agricultural development because modernization is one of the requirements to be able to compete and improve the quality of agricultural products. Methods: A qualitative approach is a research procedure that produces descriptive data in the form of written or spoken words from people and observed behavior. The descriptive-qualitative research method focuses on problems based on facts carried out by means of observation, interviews, and studying documents. Conclusion: The potential of Jaten Village that can be developed is PAD. The main livelihood of the majority of the Jaten village population is in the non-agricultural sector. The technology in Jaten Village is already very good. The internet network in Jaten Village is very easily accessible
Ekstraksi dan uji aktivitas antioksidan ekstrak etanol batang bintangur (calophyllum soulattri)
Get PDFBackground: Cigarette smoke, fried and grilled foods, excessive exposure to sunlight, motor vehicle fumes, certain drugs, toxins and air pollution are some sources of free radical compounds. As a result of homolytic breakdown, a molecule will break down into free radicals that have unpaired electrons. Electrons need a partner to balance their spin value, so that radical molecules become unstable and easily react with other molecules, forming new radicals. Findings: To prevent or reduce chronic diseases due to free radicals, antioxidants are needed. Antioxidants can slow down or inhibit the oxidation of substances that are easily oxidized even in low concentrations. Antioxidants can neutralize free radicals by donating one proton atom, making free radicals stable and non-reactive. Methods: Extraction is carried out by the maceration method, which is to soak the simplicia with ethanol solvent. This maceration process is carried out for 24 hours, then the solution containing the extract is filtered using filter paper. This maceration process is carried out three times. Conclusion: Ethanol extract of bintangur stem has quite high antioxidant activity, this can be proven by the IC50 value obtained of 3.05 ppm, this value is almost close to the IC50 value of vitamin C, which is 2.9 ppm, and by the appearance of spots in the Thin Layer Chromatography test
